SAN DIEGO — A small group of adult and pediatric patients with sickle cell disease (SCD) reached high 2-year survival after undergoing reduced-intensity haploidentical stem cell transplantation, a new phase 2 trial reports. It is much easier to find eligible haploidentical donors — half-matched or partially matched — than eligible hematopoietic donors.

Of 42 patients aged 15-45 who were fully treated, 95% survived to 2 years post transplant (overall survival, (95% CI, 81.5%-98.7%), and 88% reached the primary endpoint of event-free survival at 2 years (95% CI, 73.5%-94.8%), according to the findings, which were released at the annual meeting of the American Society of Hematology.

At an ASH news briefing, study lead author Adetola A. Kassim, MBBS, MS, of Vanderbilt University Medical Center, in Nashville, Tennessee, said the results support haploidentical stem cell transplants “as a suitable and tolerable curative therapy for adults with sickle cell disease and severe end-organ toxicity such as stroke or pulmonary hypertension, a population typically excluded from participating in gene therapy.”

Dr. Kassim added that the findings are especially promising since there are so many potential donors in stem-cell transplants: “Your siblings can be donors, your parents can be donors, your cousins can be donors. First-, second-, and third-degree relatives can be donors. So there’s really endless donors within the family.”

In an interview, Mayo Clinic SCD specialist Asmaa Ferdjallah, MD, MPH, of Mayo Clinic in Rochester, Minnesota, who was not involved with the study but is familiar with its findings, said stem cell transplant is the only option to cure SCD.

“This is advantageous because SCD is otherwise a chronic disease that is marked by chronic pain, risk of stroke, frequent interruptions of school/work due to sick days, and decreased life span,” she said. “Most patients, assuming they can tolerate the conditioning chemotherapy that is given before transplant, are eligible.”

Matched sibling donors are preferable, but they can be hard to find, she said. It hasn’t been clear whether half-matched donors are feasible options in SCD, she said. “This means that, if you are a patient with sickle cell disease, and you don’t have a suitable matched donor, haploidentical transplant is not a recommendation we can make outside of enrollment in a clinical trial.”

For the study, researchers enlisted 54 patients with SCD and prior stroke, recurrent acute chest syndrome or pain, chronic transfusion regimen, or tricuspid valve regurgitant jet velocity ≥2.7 m/sec. Participants had to have an HLA-haploidentical first-degree relative donor who would donate bone marrow.

“The median age was 22.8 years at enrollment; 47/54 (87%) of enrolled participants had hemoglobin SS disease, 40/54 (74.1%) had a Lansky/Karnofsky score of 90-100 at baseline, and 41/54 (75.9%) had an HLA match score of 4/8,” the researchers reported. “Recurrent vaso-occlusive pain episodes (38.9%), acute chest syndrome (16.8%), and overt stroke (16.7%) were the most common indications for transplant.”

“We knew going into this that we were going to get very high-risk patients,” Dr. Kassim said.

Forty-two patients went through with transplants. As for adverse events, 2 patients died, all within the first year, of organ failure and acute respiratory distress syndrome; 4.8% of participants had primary graft failure, and 2.4% had secondary graft failure before day 100. “The cumulative incidence of grades II-IV acute GVHD [graft-versus-host disease] at day 100 was 26.2% (95% CI, 14.0%-40.2%), and grades III-IV acute GVHD at day 100 was 4.8% (95% CI, 0.9%-14.4%).”

The outcomes are similar to those in transplants with matched sibling donors, Dr. Kassim said.

Dr. Ferdjallah said the new study is “robust” and impressive, although it’s small.

“As a clinician, these are the kind of outcomes I have been hoping for,” Dr. Ferdjallah said. “I have been very reluctant to suggest haploidentical transplant for my sickle cell disease patients. However, reviewing the results of this study with my motivated patients and families can help us both to use shared medical decision-making and come together with what is best for that specific patient.”

As for adverse events, she said they “confirm a fear of using haploidentical transplant, which is graft failure. Fortunately, out of 42 who proceeded to transplant, only 2 had primary graft failure and 1 had secondary graft failure. This is not overtly a large number. Of course, we would hope for more durable engraftment. The other side effects including GVHD and infection are all to be expected.”

As for cost, Dr. Kassim said the transplants run from $200,000 to $400,000 vs over $2 million for gene therapy, and Dr. Ferdjallah said insurance is likely to cover the treatment.

Moving ahead, Dr. Ferdjallah said she looks forward to getting study data about pediatric patients specifically. For now, “we should consider HLA-haploidentical seriously in patients with sickle cell disease and no available HLA-matched donors.”

Grants to the Blood and Marrow Transplant Clinical Trials Network from the National Heart, Lung, and Blood Institute and National Cancer Institute funded the study. Dr. Kassim had no disclosures. Some other authors disclosed various and multiple relationships with industry. Dr. Ferdjallah has no disclosures.

SAN DIEGO — A newly approved gene therapy product for sickle cell disease, lovotibeglogene autotemcel (lovo-cel, marketed as Lyfgenia), led to durable disease remissions for up to 5 years and almost complete elimination of dangerous and debilitating vaso-occlusive events, according to results of a long-term follow-up study.

More specifically, a single infusion of lovo-cel led to complete resolution of vaso-occlusive events in 88% of patients, with 94% achieving complete resolution of severe events. All 10 adolescents in the study achieved complete resolution of vaso-occlusive events. Most patients remained free of vaso-occlusive events at their last follow-up.

“This is a one-time, truly transformative treatment with lovo-cel,” lead author Julie Kanter, MD, director of the adult sickle cell clinic at the University of Alabama in Birmingham, said in a media briefing at the annual meeting of the American Society of Hematology. The gene therapy can essentially eliminate vaso-occlusive events in patients with sickle cell disease and lead to normal hemoglobin levels, Dr. Kanter added. 

For “anybody who has rounded on the inpatient floor and taken care of adolescents admitted with a pain crisis multiple times a year,” seeing these results “is so compelling,” commented Sarah O’Brien, MD, a pediatric hematologist at Nationwide Children’s Hospital in Columbus, Ohio, who moderated the briefing but was not involved in the study.
 

One and Done

Sickle cell disease, a debilitating and potentially life-threatening blood disorder, affects an estimated 100,000 people in the US. 

People with the condition have a mutation in hemoglobin, which causes red blood cells to develop an abnormal sickle shape. These sickled cells block the flow of blood, ultimately depriving tissues of oxygen and leading to organ damage and severe pain, known as vaso-occlusive events. 

On Dec. 8, the U.S. Food and Drug Administration (FDA) approved lovo-cel for patients aged 12 years or older with severe sickle cell disease alongside another gene-editing therapy called exagamglogene autotemcel or exa-cel (Casgevy, Vertex Pharmaceuticals and Crispr Therapeutics). The two therapies use different gene-editing approaches — exa-cel is the first to use the gene-editing tool CRISPR while lovo-cel uses a lentiviral vector.

Both are one-time, single-dose cell-based gene therapies.

With lovo-cel, patients first undergo a transfusion regimen and myeloablative conditioning with busulfan to collect cells that can then be genetically modified. A patient’s harvested cells are modified with an anti-sickling version of hemoglobin A, HbAT87Q. Patients then receive an infusion of these edited cells and remain in the hospital during engraftment and reconstitution.

Dr. Kanter presented long-term follow-up data on 47 patients enrolled in phase 1/2 and phase 3 studies of lovo-cel. 

All patients had stable HbAT87Q levels from 6 months to their last follow-up at a median of 35.5 months. 

Most patients achieved a durable globin response through their final follow-up visit.

Among the 34 evaluable patients, 88% had complete resolution of vaso-occlusive events 6 to 18 months after their infusion, including all 10 adolescent patients. Almost all patients (94%) achieved complete resolution of serious vaso-occlusive events. 

In the few patients who experienced posttreatment vaso-occlusive events, these individuals still achieved major reductions in hospital admissions and hospital days.

Among 20 patients followed for at least 3 years, more than half had clinically meaningful improvements in pain intensity, pain interference, and fatigue.

Most treatment-related adverse events occurred within 1 year of lovo-cel infusions and were primarily related to busulfan conditioning. No cases of veno-occlusive liver disease, graft failure, or graft vs host disease occurred, and patients did not have complications related to the viral vector. No patients who had a history of stroke prior to lovo-cel therapy experienced a post-therapy stroke. 

One patient died at baseline from significant cardiopulmonary disease related to sickle cell disease, but the death was considered unrelated to lovo-cel therapy.

To see a one-time treatment that essentially eradicates vaso-occlusive events is “really unparalleled,” said Steven Pipe, MD, from the University of Michigan School of Medicine in Ann Arbor, who presented data on a different study at the briefing.

However, Dr. Kanter noted, “it’s important to highlight that many of these individuals come into this therapy with significant disease and end-organ complications, and this will be something we will really need to follow long-term to understand how much this therapy can stabilize or reverse these complications.”

The studies were funded by bluebird bio. Dr. Kanter disclosed honoraria from the company and consulting/advising activities and receipt of research funding from multiple other entities. Dr. O’Brien disclosed consultancy for AstraZeneca, honoraria from Pharmacosmos, and research funding from Bristol Myers Squibb. Dr. Pipe disclosed consulting activities from multiple companies, not including bluebird bio.

The U.S. Food and Drug Administration on Dec. 8 approved two gene-editing treatments for patients aged 12 years or older with severe sickle cell disease.

These “milestone treatments” mark the first cell-based gene therapies for this debilitating and potentially life-threatening blood disorder that affects about 100,000 people in the United States.

The two therapies are exagamglogene autotemcel, or exa-cel (Casgevy; Vertex Pharmaceuticals and Crispr Therapeutics), and lovotibeglogene autotemcel, or lovo-cel (Lyfgenia; bluebird bio). 

“The approval of the first gene therapies for [sickle cell disease] represents a tremendous step forward for the [sickle cell] community, which has been historically overlooked and underfunded,” said Robert A. Brodsky, MD, of Johns Hopkins University School of Medicine, in a statement from the American Society of Hematology, following the approval.

“We are excited to advance the field, especially for individuals whose lives have been severely disrupted by the disease, by approving two cell-based gene therapies today,” Nicole Verdun, MD, of the FDA’s Center for Biologics Evaluation and Research, added in an agency press release.

Sickle cell disease involves a mutation in hemoglobin, a protein in red blood cells that provides oxygen to tissues. The mutation leads red blood cells to develop a crescent or sickle shape, which can restrict blood flow and cause severe pain and organ damage, known as vaso-occlusive events or crises. 

Treatment options prior to these approvals primarily included red blood transfusions and hydroxyurea alongside pain management. The only potential curative option has been allogeneic hematopoietic stem cell transplantation, but that comes with significant risks and most patients don’t have an appropriate donor.

Exa-cel

Exa-cel uses CRISPR gene-editing technology. Before the infusion, patients undergo myeloablative conditioning, which removes cells from the bone marrow. These cells are genetically modified to produce fetal hemoglobin. Patients then receive an infusion of the edited cells, which can help restore normal hemoglobin production. 

The FDA approval was based on data from the pivotal CLIMB SCD-121 trial. In an October advisory committee meeting, the FDA highlighted trial data demonstrating that 29 of 31 patients reached the trial’s primary endpoint: freedom from severe vaso-occlusive crises over a 12-month period. In addition, 28 of these patients remained free of vaso-occlusive crises for almost 2 years.

The committee noted that one of the 31 patients died about 9 months after receiving an exa-cel infusion. 

The cell-based gene therapy also increased both fetal and total hemoglobin, with total hemoglobin levels increasing to > 11 g/dL by month 3 and remaining at that level afterward. No patients experienced graft failure or rejection.

The most common side effects included low platelets and white blood cell counts, mouth sores, nausea, musculoskeletal pain, vomiting, and febrile neutropenia. 

Exa-cel could “provide a one-time functional cure” for patients with severe sickle cell disease, according to Franco Locatelli, MD, of Sapienza University of Rome, who presented initial findings last year.

While the current approval is for patients with infusion-dependent sickle cell disease, exa-cel is also being evaluated in patients with another blood disorder, beta-thalassemia.

Lovo-cel

Lovo-cel, a cell-based gene therapy, uses a different technology — a lentiviral vector, or gene delivery vehicle — that can also genetically modify a patient’s blood stem cells. 

Like exa-cel, lovo-cel is a one-time, single-dose infusion that contains the patient’s modified cells. Before the infusion, patients undergo myeloablative conditioning. The patient’s stem cells are then genetically modified to allow them to produce the most common form of hemoglobin, HbA 

This approval was based on data from a single-arm, 24-month study in patients aged 12-50 years who had sickle cell disease and a history of vaso-occlusive events. 

Overall, 88% of patients (28 of 32) achieved complete resolution of vaso-occlusive events 6-18 months after the infusion. 

The most common side effects included stomatitis; febrile neutropenia; and low platelet, white blood cell, and red blood cell counts.

The FDA noted that hematologic cancer has occurred in patients treated with lovo-cel, and the label includes a black-box warning about the risk. 

Dr. Brodsky noted, however, that “while these new gene therapies are potentially life-changing for individuals living with [sickle cell disease], they must be accessible to be effective.”

Access is a potential concern. Exa-cel and lovo-cel could cost about $2 million.

The U.S. Food and Drug Administration on Dec. 8 approved two gene-editing treatments for patients aged 12 years or older with severe sickle cell disease.

These “milestone treatments” mark the first cell-based gene therapies for this debilitating and potentially life-threatening blood disorder that affects about 100,000 people in the United States.

The two therapies are exagamglogene autotemcel, or exa-cel (Casgevy; Vertex Pharmaceuticals and Crispr Therapeutics), and lovotibeglogene autotemcel, or lovo-cel (Lyfgenia; bluebird bio). 

“The approval of the first gene therapies for [sickle cell disease] represents a tremendous step forward for the [sickle cell] community, which has been historically overlooked and underfunded,” said Robert A. Brodsky, MD, of Johns Hopkins University School of Medicine, in a statement from the American Society of Hematology, following the approval.

“We are excited to advance the field, especially for individuals whose lives have been severely disrupted by the disease, by approving two cell-based gene therapies today,” Nicole Verdun, MD, of the FDA’s Center for Biologics Evaluation and Research, added in an agency press release.

Sickle cell disease involves a mutation in hemoglobin, a protein in red blood cells that provides oxygen to tissues. The mutation leads red blood cells to develop a crescent or sickle shape, which can restrict blood flow and cause severe pain and organ damage, known as vaso-occlusive events or crises. 

Treatment options prior to these approvals primarily included red blood transfusions and hydroxyurea alongside pain management. The only potential curative option has been allogeneic hematopoietic stem cell transplantation, but that comes with significant risks and most patients don’t have an appropriate donor.

Exa-cel

Exa-cel uses CRISPR gene-editing technology. Before the infusion, patients undergo myeloablative conditioning, which removes cells from the bone marrow. These cells are genetically modified to produce fetal hemoglobin. Patients then receive an infusion of the edited cells, which can help restore normal hemoglobin production. 

The FDA approval was based on data from the pivotal CLIMB SCD-121 trial. In an October advisory committee meeting, the FDA highlighted trial data demonstrating that 29 of 31 patients reached the trial’s primary endpoint: freedom from severe vaso-occlusive crises over a 12-month period. In addition, 28 of these patients remained free of vaso-occlusive crises for almost 2 years.

The committee noted that one of the 31 patients died about 9 months after receiving an exa-cel infusion. 

The cell-based gene therapy also increased both fetal and total hemoglobin, with total hemoglobin levels increasing to > 11 g/dL by month 3 and remaining at that level afterward. No patients experienced graft failure or rejection.

The most common side effects included low platelets and white blood cell counts, mouth sores, nausea, musculoskeletal pain, vomiting, and febrile neutropenia.

The US Food and Drug Administration (FDA) has approved iptacopan (Fabhalta, Novartis), the first oral monotherapy for both treatment-naive and pretreated adults with paroxysmal nocturnal hemoglobinuria (PNH).

Iptacopan, a factor B inhibitor, offers “superior hemoglobin improvement in the absence of transfusions” in patients with this rare chronic blood disorder, according to a Novartis press release.

“An efficacious oral treatment with a demonstrated safety profile could be practice-changing for physicians and help relieve burdens experienced by people with PNH,” Vinod Pullarkat, MD, of City of Hope Cancer Center, Duarte, California, said in the company press release.

Previously, the only approved treatments for PNH were injectable C5 complement inhibitors.

The latest approval was based on the randomized, open-label, phase 3 APPLY-PNH trial in 97 adults with PNH and anemia and was supported by safety and efficacy findings from the phase 3, single-arm APPOINT-PNH study in 40 C5 complement inhibitor–naive patients.

APPLY-PNH participants included adults with residual anemia receiving a stable regimen of anti-C5 treatment in the prior 6 months. Patients were randomly assigned to switch to 200 mg of iptacopan (n = 62) given twice daily or to remain on the anti-C5 therapy (n = 35).

The investigators reported greater increases in hemoglobin levels in patients who switched to iptacopan, with sustained increases ≥ 2 g/dL in 82.3% compared with 0% of patients who did not switch. Investigators also observed increases ≥ 12 g/dL in 67.7% of patients who switched vs 0% of those who did not. Almost all patients (95.2%) in the iptacopan group avoided a red blood cell transfusion vs 45.7% among patients who did not switch.

In the APPLY-PNH trial, common adverse reactions with iptacopan vs anti-C5 therapy included headache(19% vs 3%), nasopharyngitis (16% vs 17%), diarrhea (15% vs 6%), abdominal pain (15% vs 3%), bacterial infection(11% vs 11%), nausea (10% vs 3%), and viral infection(10% vs. 31%). Two patients experienced serious adverse events, which included pyelonephritis, urinary tract infection, and COVID-19.

In the APPOINT-PNH trial, the most common adverse events were headache (28%), viral infection (18%), nasopharyngitis (15%), and rash (10%). Serious adverse events, reported in two patients (5%), included COVID-19 and bacterial pneumonia.

“Fabhalta may cause serious infections caused by encapsulated bacteria and is available only through a Risk Evaluation and Mitigation Strategy (REMS) that requires vaccinations for encapsulated bacteria,” Novartis cautioned.

Talk about bloodlines: In the Brodsky family, the field of hematology tied father to son. Now a grandson is heading into the “family business.” This extraordinary legacy ties the late Isadore Brodsky, a pioneering hematologist, to his son Robert A. Brodsky, current president of the American Society of Hematology (ASH), and grandson Max Brodsky, now a second-year hematology fellow.

In interviews, Robert and Max Brodsky spoke about the appeal of hematology and the threads that unite them with family members who came before. The elder Brodsky also talked about the work that’s made him the proudest during his year-long presidency at ASH.

166208_photo_web.JPG

Robert A. Brodsky is professor of medicine and director of hematology at Johns Hopkins University, Baltimore. He is stepping down as ASH president at its annual meeting in San Diego, December 9-12. Here are excerpts from our conversation:

Q: What drew your dad into medicine?

Dr. Robert A. Brodsky: He was going through his medical training at the University of Pennsylvania, then the Vietnam War came, and he served at the National Institutes of Health in what they referred to as the Yellow Berets. He got very interested in retroviruses and viruses that lead to cancer, which was a foreign idea at the time. This led him into hematology, stem cells, and myeloproliferative disorders.

He had a very successful career in hematology and just loved it. He performed the first bone marrow transplant in the tristate area of Pennsylvania, Delaware, and New Jersey.

Q: What did he like about hematology specifically?

Dr. Robert A. Brodsky: It’s a fascinating field, probably the most scientific area of medicine. It’s so easy to access blood and bone marrow. You can grow it, you can look at it, you can see it. It’s hard to do that with a lung, heart, kidney, or brain. Even back then, they could translate some of the science. What really drew him to hematology — and me, for that matter — was looking at a blood smear or bone marrow and being able to make a diagnosis. The other thing is the personal aspect. Hematologists tend to like the long-term relationships that they develop with their patients over the years.

Q: What were the biggest transformations in hematology during his career?

Dr. Robert A. Brodsky: Bone marrow transplant had the biggest impact, and it’s an area he really pioneered. He was very much involved in some of the early bone marrow transplants and was very close with Dr. George W. Santos, who was at Johns Hopkins and one of the big pioneers in that area as well. To be able to take marrow from related donors, get it to grow without the patient rejecting it, and cure a disease, was really huge. When he started doing this, patients had no other option. To see patients be cured was incredibly satisfying to him.

Q: How did you end up following your father into hematology?

Dr. Robert A. Brodsky: My brother Jeff, who’s a surgeon and older than me, knew he was going into medicine — probably about 3 hours after he was born. I came to it late. I was a political science major as an undergrad and really trying to figure out what I wanted to do. In my sophomore year, I decided I wanted to give this a shot. My dad worked very hard, long hours, but you could tell he loved what he did. And he was never absent, always involved in our lives and still made time for everyone. At some level, that must have had an influence on me.

Q: What has changed in hematology over your 30-plus years in medicine?

A: When I look back at when I was a fellow, it’s just mind-boggling how many lethal or life-threatening diseases are now pretty easy to treat. I studied disorders like aplastic anemia, which was very fatal. Without treatment, patients would die within a year. Now, over 95% are cured. Another classic examples is chronic myeloid leukemia disorder. Back when I was a fellow, the median survival for CML was maybe 4 to 6 years. Now, Kareem Abdul Jabbar has had this[for about 15 years]. Also a lot of hematologic malignancies are being cured with immunotherapy approaches. We’ve figured out the pathophysiology of a lot of diseases, and there are incredible genetic diagnostic assays.

Q: What was your father’s relationship with ASH?

Dr. Robert A. Brodsky: The first ASH meeting was 1958 in Atlantic City, New Jersey. There were 300 hematologists there, and my dad was one of them. We’re going to have over 30,000 people in San Diego, which is a record, and another 5,000 or 6,000 virtually.

Q: As ASH president, what are your biggest accomplishments when it comes to addressing the shortage of hematologists and other issues?

Dr. Robert A. Brodsky: ASH is investing $19 million to develop fellowships with a focus on hematology.* This is going to put lots of new hematologists into the workforce over the next 5 to 10 years. We’ve also been working on the Maintenance of Certification [MOC] process to make it less onerous on physicians. It’s really a bad process, and it’s not just ASH [that’s complaining], it’s all of medicine. We’re hearing this from GI, endocrine, renal and the general internists.

[In a September 2023 letter to the American Board of Internal Medicine’s president and chief officer, Dr. Brodsky wrote that “ASH continues to support the importance of lifelong learning for hematologists via a program that is evidence-based, relevant to one’s practice, and transparent; however, these three basic requirements are not met by the current ABIM MOC program.” ASH is calling for a new and reformed MOC program.]

Q: What convinced ASH to expand its journals by adding Blood Neoplasia and Blood Vessels, Thrombosis & Hemostasis?

Dr. Robert A. Brodsky: ASH has two flagship journals right now, Blood and Blood Advances, and they’re both very competitive, high-impact journals. It turns out there’s not enough room to publish all the new science, and they end up rejecting the majority of the submissions that come to them. We decided to keep these journals in the ASH family because there’s some fantastic clinical trials and science that would be going elsewhere.

Dr. Brodsky’s sons both have medical degrees: Brett Brodsky, DO, is a resident at Virginia Commonwealth University who plans to become a sports medicine specialist, and Max Brodsky, MD, is a second-year fellow in hematology at Johns Hopkins University.

In an interview, Max Brodsky, MD, talked about the roots of his family’s dedication to caring for others.

Q: What drew you to hematology?

Dr. Max Brodsky: I’ve watched both my dad and my grandfather be leaders in the field as both physicians and scientists, and that was very inspirational for me to see. And I went to a medical school [Drexel University College of Medicine] that my dad went to and where my grandfather was on faculty. That was like walking in their footsteps in a major way.

Q: What do you hope to focus on as a hematologist?

Dr. Max Brodsky: I’m still working through that, but I am really interested in thrombotic thrombocytopenic purpura. Patients used to not be able to survive their initial episodes, but now we have good treatments and are able to follow them as outpatients. With this whole cohort of patients that are surviving, we’re seeing that they have more health problems — more heart disease, more strokes and kidney disease. There’s a whole growing field exploring how to treat these patients for their lifespan.

Q: How do you deal with the reality that more of your patients will die than in some other medical fields?

Dr. Max Brodsky: It is challenging, but I also see those moments as opportunities to support patients and families. I’m good at connecting to patients and families who are in scary situations. I’ve always had that skill of putting people at ease, making people feel calm, knowing that they can trust me, and I have their best interests in mind.

Q: Why do you think your family is so committed to medicine?

Dr. Max Brodsky: We’re Jewish, and looking to help the world is one of the main core values of Judaism. The Torah expects us to make this world better.  Actually, my great-grandfather Max, whom I’m named after, used to dig tunnels to help people escape Ukraine and get to freedom. He was always looking to help others as well. My great-grandmother was shot crossing the border escaping from Ukraine, and he carried her the whole way to the boat. They lived in very poor West Philadelphia and poured everything into my grandfather. He became a great doctor, and his sons and his grandchildren are in medicine today.

*Correction, 12/11: A previous version of this story misstated the amount of ASH’s $19 million investment in developing fellowships with a focus on hematology.

Dr. Robert A. Brodsky: ASH has two flagship journals right now, Blood and Blood Advances, and they’re both very competitive, high-impact journals. It turns out there’s not enough room to publish all the new science, and they end up rejecting the majority of the submissions that come to them. We decided to keep these journals in the ASH family because there’s some fantastic clinical trials and science that would be going elsewhere.

Dr. Brodsky’s sons both have medical degrees: Brett Brodsky, DO, is a resident at Virginia Commonwealth University who plans to become a sports medicine specialist, and Max Brodsky, MD, is a second-year fellow in hematology at Johns Hopkins University.

In an interview, Max Brodsky, MD, talked about the roots of his family’s dedication to caring for others.

Q: What drew you to hematology?

Dr. Max Brodsky: I’ve watched both my dad and my grandfather be leaders in the field as both physicians and scientists, and that was very inspirational for me to see. And I went to a medical school [Drexel University College of Medicine] that my dad went to and where my grandfather was on faculty. That was like walking in their footsteps in a major way.

Q: What do you hope to focus on as a hematologist?

Dr. Max Brodsky: I’m still working through that, but I am really interested in thrombotic thrombocytopenic purpura. Patients used to not be able to survive their initial episodes, but now we have good treatments and are able to follow them as outpatients. With this whole cohort of patients that are surviving, we’re seeing that they have more health problems — more heart disease, more strokes and kidney disease. There’s a whole growing field exploring how to treat these patients for their lifespan.

Q: How do you deal with the reality that more of your patients will die than in some other medical fields?

Dr. Max Brodsky: It is challenging, but I also see those moments as opportunities to support patients and families. I’m good at connecting to patients and families who are in scary situations. I’ve always had that skill of putting people at ease, making people feel calm, knowing that they can trust me, and I have their best interests in mind.

Q: Why do you think your family is so committed to medicine?

Dr. Max Brodsky: We’re Jewish, and looking to help the world is one of the main core values of Judaism. The Torah expects us to make this world better.  Actually, my great-grandfather Max, whom I’m named after, used to dig tunnels to help people escape Ukraine and get to freedom. He was always looking to help others as well. My great-grandmother was shot crossing the border escaping from Ukraine, and he carried her the whole way to the boat. They lived in very poor West Philadelphia and poured everything into my grandfather. He became a great doctor, and his sons and his grandchildren are in medicine today.

Talk about bloodlines: In the Brodsky family, the field of hematology tied father to son. Now a grandson is heading into the “family business.” This extraordinary legacy ties the late Isadore Brodsky, a pioneering hematologist, to his son Robert A. Brodsky, current president of the American Society of Hematology (ASH), and grandson Max Brodsky, now a second-year hematology fellow.

In interviews, Robert and Max Brodsky spoke about the appeal of hematology and the threads that unite them with family members who came before. The elder Brodsky also talked about the work that’s made him the proudest during his year-long presidency at ASH.

Robert A. Brodsky is professor of medicine and director of hematology at Johns Hopkins University, Baltimore. He is stepping down as ASH president at its annual meeting in San Diego, December 9-12. Here are excerpts from our conversation:

Q: What drew your dad into medicine?

Dr. Robert A. Brodsky: He was going through his medical training at the University of Pennsylvania, then the Vietnam War came, and he served at the National Institutes of Health in what they referred to as the Yellow Berets. He got very interested in retroviruses and viruses that lead to cancer, which was a foreign idea at the time. This led him into hematology, stem cells, and myeloproliferative disorders.

He had a very successful career in hematology and just loved it. He performed the first bone marrow transplant in the tristate area of Pennsylvania, Delaware, and New Jersey.

Q: What did he like about hematology specifically?

Dr. Robert A. Brodsky: It’s a fascinating field, probably the most scientific area of medicine. It’s so easy to access blood and bone marrow. You can grow it, you can look at it, you can see it. It’s hard to do that with a lung, heart, kidney, or brain. Even back then, they could translate some of the science. What really drew him to hematology — and me, for that matter — was looking at a blood smear or bone marrow and being able to make a diagnosis. The other thing is the personal aspect. Hematologists tend to like the long-term relationships that they develop with their patients over the years.

Q: What were the biggest transformations in hematology during his career?

Dr. Robert A. Brodsky: Bone marrow transplant had the biggest impact, and it’s an area he really pioneered. He was very much involved in some of the early bone marrow transplants and was very close with Dr. George W. Santos, who was at Johns Hopkins and one of the big pioneers in that area as well. To be able to take marrow from related donors, get it to grow without the patient rejecting it, and cure a disease, was really huge. When he started doing this, patients had no other option. To see patients be cured was incredibly satisfying to him.

Q: How did you end up following your father into hematology?

Dr. Robert A. Brodsky: My brother Jeff, who’s a surgeon and older than me, knew he was going into medicine — probably about 3 hours after he was born. I came to it late. I was a political science major as an undergrad and really trying to figure out what I wanted to do. In my sophomore year, I decided I wanted to give this a shot. My dad worked very hard, long hours, but you could tell he loved what he did. And he was never absent, always involved in our lives and still made time for everyone. At some level, that must have had an influence on me.

Q: What has changed in hematology over your 30-plus years in medicine?

A: When I look back at when I was a fellow, it’s just mind-boggling how many lethal or life-threatening diseases are now pretty easy to treat. I studied disorders like aplastic anemia, which was very fatal. Without treatment, patients would die within a year. Now, over 95% are cured. Another classic examples is chronic myeloid leukemia disorder. Back when I was a fellow, the median survival for CML was maybe 4 to 6 years. Now, Kareem Abdul Jabbar has had this[for about 15 years]. Also a lot of hematologic malignancies are being cured with immunotherapy approaches. We’ve figured out the pathophysiology of a lot of diseases, and there are incredible genetic diagnostic assays.

Q: What was your father’s relationship with ASH?

Dr. Robert A. Brodsky: The first ASH meeting was 1958 in Atlantic City, New Jersey. There were 300 hematologists there, and my dad was one of them. We’re going to have over 30,000 people in San Diego, which is a record, and another 5,000 or 6,000 virtually.

Q: As ASH president, what are your biggest accomplishments when it comes to addressing the shortage of hematologists and other issues?

Dr. Robert A. Brodsky: ASH is investing $19 million to develop fellowships with a focus on hematology.* This is going to put lots of new hematologists into the workforce over the next 5 to 10 years. We’ve also been working on the Maintenance of Certification [MOC] process to make it less onerous on physicians. It’s really a bad process, and it’s not just ASH [that’s complaining], it’s all of medicine. We’re hearing this from GI, endocrine, renal and the general internists.

Health equity, sickle cell disease (SCD), and the thoughtful use of artificial intelligence (AI) and social media are among the key themes to be presented at the Dec. 9-12 annual meeting of the American Society of Hematology (ASH) in San Diego, association leaders told reporters in a media preview session.

Cynthia E. Dunbar, MD, chief of the Translational Stem Cell Biology Branch at the National Heart, Lung, and Blood Institute and secretary of ASH, added that insight into actual patient experiences also will be a major theme at ASH 2023.

“There is a huge growth in research on outcomes and focusing on using real-world data and how important that is,” Dr. Dunbar said. “Academic research and hematology is really focusing on patient-reported outcomes and how care is delivered in a real-world setting – actually looking at what matters to patients. Are they alive in a certain number of years? And how are they feeling?”

As an example, Dr. Dunbar pointed to an abstract that examined clinical databases in Canada and found that real-world outcomes in multiple myeloma treatments were much worse than those in the original clinical trials for the therapies. Patients reached relapse 44% faster and their overall survival was 75% worse.

In the media briefing, ASH chair of communications Mikkael A. Sekeres, MD, MS, of the Sylvester Comprehensive Cancer Center at the University of Miami, noted that patients in these types of clinical trials “are just these pristine specimens of human beings except for the cancer that’s being treated.”

Dr. Dunbar agreed, noting that “patients who are able to enroll in clinical trials are more likely to be able to show up at the treatment center at the right time and for every dose, have transportation, and afford drugs to prevent side effects. They might stay on the drug for longer, or they have nurses who are always encouraging them of how to make it through a toxicity.”

Hematologists and patients should consider randomized controlled trials to be “the best possible outcome, and perhaps adjust their thinking if an individual patient is older, sicker, or less able to follow a regimen exactly,” she said.

Another highlighted study linked worse outcomes in African-Americans with pediatric acute myeloid leukemia to genetic traits that are more common in that population. The traits “likely explain at least in part the worst outcomes in Black patients in prior studies and on some regimens,” Dr. Dunbar said.

She added that the findings emphasize how testing for genetic variants and biomarkers that impact outcomes should be performed “instead of assuming that a certain dose should be given simply based on perceived or reported race or ethnicity.”

ASH President Robert A. Brodsky, MD, of Johns Hopkins University School of Medicine, Baltimore, highlighted an abstract that reported on the use of AI as a clinical decision support tool to differentiate two easily confused conditions — prefibrotic primary myelofibrosis and essential thrombocythemia.

AI “is a tool that’s going to help pathologists make more accurate and faster diagnoses,” he said. He also spotlighted an abstract about the use of “social media listening” to understand the experiences of patients with SCD and their caregivers. “There can be a lot of misuse and waste of time with social media, but they used this in a way to try and gain insight as to what’s really important to the patients and the caregiver.”

Also, in regard to SCD, Dr. Dunbar pointed to a study that reports on outcomes in patients who received lovotibeglogene autotemcel (lovo-cel) gene therapy for up to 60 months. Both this treatment and a CRISPR-based therapy called exa-cel  “appear to result in comparable very impressive efficacy in terms of pain crises and organ dysfunction,” she said. “The hurdle is going to be figuring out how to deliver what will be very expensive and complicated therapies — but likely curative — therapies to patients.”

Another study to be presented at ASH — coauthored by Dr. Brodsky — shows promising results from reduced-intensity haploidentical bone marrow transplantation in adults with severe SCD. Results were similar to those seen with bone marrow from matched siblings, Dr. Sekeres said.

He added that more clarity is needed about new treatment options for SCD, perhaps through a “randomized trial where patients upfront get a haploidentical bone marrow transplant or fully matched bone marrow transplant. Then other patients are randomized to some of these other, newer technology therapies, and we follow them over time. We’re looking not only for overall survival but complications of the therapy itself and how many patients relapse from the treatment.”

The U.S. Food and Drug Administration has approved the biologic Adzynma (ADAMTS13, recombinant-krhn, Takeda Pharmaceuticals) to treat adults and children who have a rare and life-threatening blood clotting disorder called congenital thrombotic thrombocytopenic purpura (TTP). Adzynma is the first recombinant protein product for preventive or on-demand enzyme replacement therapy for people with the blood clotting condition.

Congenital TTP affects fewer than 1,000 people in the United States and is caused by a mutation in the ADAMTS13 gene, which makes an enzyme that regulates blood clotting. Patients with the congenital TTP typically receive prophylactic plasma-based therapy to replenish the ADAMTS13 enzyme and reduce the risk for clotting and bleeding. The condition, however, can be fatal if left untreated.

The new agent is a purified recombinant form of the ADAMTS13 enzyme that works by replacing low levels of the deficient enzyme in patients with congenital TTP. Adzynma is given prophylactically to reduce the risk for disease symptoms and on demand when a patient is experiencing an acute event, according to the FDA approval announcement.

The approval was based on a global randomized phase 3 study comparing the product with plasma-based therapies in 46 patients with congenital TTP. Patients in the trial were randomized to receive 6 months of treatment with either intravenous Adzynma — given once every other week as prophylactic enzyme replacement therapy or once daily as on-demand enzyme replacement therapy — or plasma-based therapies. The patients then crossed over to the other treatment for 6 months.

Interim findings from the study showed that Adzynma reduced the incidence of thrombocytopenia — the most common symptom of congenital TTP — by 60% compared with plasma-based therapy (rate ratio, 0.40). No patients experienced an acute TTP event during Adzynma prophylaxis, Takeda said.

Significantly more patients receiving plasma-based therapies experienced treatment-emergent adverse events compared with those receiving the biologic.

The most common side effects associated with the biologic were headache (31.3%), diarrhea (16.7%), migraine (14.6%), abdominal pain (12.5%), nausea (12.5%), upper respiratory tract infection (12.5%), dizziness (10.4%), and vomiting (10.4%). No treatment-related adverse events, including allergic reactions, were observed during administration.

“The FDA remains deeply committed in our efforts to help facilitate the development and approval of safe and effective therapies for patients with rare diseases,” Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, stated. The “approval reflects important progress in the development of much-needed treatment options for patients affected by this life-threatening disorder.”

Having grown up with sickle cell disease (SCD), Titilope Fasipe, MD, PhD, codirector of the sickle cell program at Texas Children’s Hospital in Houston, knows firsthand the physical pain, mental anguish, and dread that have long accompanied this condition. So few child patients lived to reach adulthood that until recently, SCD was considered a pediatric disease.

These days, thanks to transformative advances in treating SCD that have substantially improved survival, Dr. Fasipe’s mission for a new generation of patients and their families is to replace their pain and fear with relief and hope.

“If you grow up thinking that you’re going to die when you’re 18, it changes your world and your viewpoints, and it impacts your mental health,” she told this news organization.

“We are trying to make sure our children and their families know that there is a new story for sickle cell disease, and you don’t have to use any age as your prediction marker for your lifespan,” Dr. Fasipe said.

SCD, which affects about 100,000 people nationwide, is an inherited blood disorder, with the majority of patients – but not all – being of African descent. This condition is characterized by pain crises, or vaso-occlusive episodes, triggered when cells that are sickled get stuck and impede blood flow. These crises can come on suddenly and range from mild to severe.

Dr. Fasipe was born in Nigeria, where rates of SCD are among the world’s highest. She attended elementary school in the United States, where her father was studying theology, before returning to Nigeria with her family at age 11.

Back in those days, in both nations only about 50% of children with SCD lived beyond their 18th birthday. The survival rates in Nigeria and sub-Saharan Africa countries continue to be poor. In some more developed regions elsewhere, advances such as universal newborn screening, penicillin prophylaxis, pneumococcal vaccination, stroke screening, and hydroxyurea therapy have yielded substantial improvements, with 95% or more patients with SCD reaching their 18th birthday.

“With measures such as newborn screening, we can immediately start prevention measures in sickle cell disease, such as prevention of infection, which was the number one reason why children were dying,” Dr. Fasipe explained. “With global initiatives, we want that story to be the same in sub-Saharan Africa as well.”
 

Cousin’s early death inspires medical studies

In an essay published by Texas Medical Center that describes her childhood experiences, Dr. Fasipe recounts a pivotal event in her life: The heartbreaking death of her beloved cousin at the age of just 17, from a complication of SCD. This bereavement fueled Dr. Fasipe’s determination to pursue a medical career, to do all that she could to prevent such losses.

“Having sickle cell disease myself wasn’t the trigger that made me become a doctor. But when Femi [her cousin] died, I thought: ‘This shouldn’t happen,’ ” Dr. Fasipe wrote.

When she applied to medical school back in the United States, she declared in her application essay: “I want to cure sickle cell.”

By the time Dr. Fasipe was ready to undertake residency and fellowship applications, her essay had shifted to focus on pediatrics “specifically because I want to reach sickle cell patients before they’ve defined how their lives are going to be,” she said. “I want to give them hope.”
 

Hope for a cure

Fast-forwarding to this point in Dr. Fasipe’s career, she noted that her dream of a cure for SCD is no longer a distant aspiration, thanks to the advent of stem cell transplantation and more recently, gene therapy. These advancements have elevated her hope for a cure to an entirely new level.

Each new treatment comes with caveats. Stem cell transplantation requires a matching donor, leaving the majority of patients ineligible. And while gene therapy eliminates the need for a donor, treatment can reportedly cost nearly $3 million. Nevertheless, Dr. Fasipe emphasized the promise that these new advancements represent.

“The scientists that work in these spaces do appreciate these [accessibility barriers], and the expectation is these therapies will be more accessible with time and effort,” she said. “We’ve got to start somewhere, and it’s exciting that they’re making these early successes.”
 

Advice for clinicians

With firsthand knowledge of how it feels to be the patient, as well as on the clinician side of SCD treatment, Dr. Fasipe advises colleagues on some ways that they can improve care while boosting their patients’ hope:

Speak with empathy

Acknowledge the ‘elephant in the room’; the pain that patients with SCD can experience is real.

“When I’m managing any patient with pain, I first acknowledge the suffering because while we may not understand what that person is going through, acknowledgment is part of showing empathy,” she explains.

Seek out resources

Patients with SCD may typically seek treatment in primary care, where expertise in the disease may be lacking, and general practitioners may feel frustrated that there are limited treatment options.

“If you do find yourself treating a sickle cell disease patient, you may not have all of the answers, but there are good resources, whether it’s a nearby sickle cell disease centers or national guidelines,” Dr. Fasipe said.

Access to treatment

With research, including a recent study, showing that only about 25% of patients with SCD are prescribed hydroxyurea and even fewer – only about 5% – receive more recently approved SCD treatments, clinicians should be proactive by making sure that patients receive needed treatments.

“Clearly medicines like hydroxyurea are not as optimized in this community space as they should be, and then there are newer therapies that families, patients, and even providers may not be aware of, so it is important to be informed of the guidelines and provide all patients with comprehensive, high-quality care,” Dr. Fasipe said.

In the ED, patients with SCD are ‘care-seeking,’ not drug-seeking

Due to the sometimes rapid onset of severe pain symptoms, patients with SCD commonly wind up in the emergency department. In this time of an opioid epidemic, patients too often are suspected of merely seeking drugs.

“Sickle cell disease tends to get lumped into a category of a disease of pain, but pain is subjective and it is difficult to quantify, so unfortunately, patients can be labeled as potentially drug-seeking,” Dr. Fasipe explained, citing an article that detailed this problem.

Consequently, patients may have particularly negative experiences in the emergency department, but the use of resources such as a sickle cell disease point-of-care tool developed by the American College of Emergency Physicians and the American Society of Hematology can help improve care for those patients.

“One of the [point-of-care recommendations] before even managing the pain is that physicians show compassion by acknowledging the patient’s pain and that they understand why pain with sickle cell disease might look different than other types of pain,” Dr. Fasipe said.
 

Building trust

Encounters such as negative emergency department experiences can perpetuate a deeper issue of distrust between those with SCD and the medical community, which originated in long-held, well-documented racial disparities in health care.

“We know historically and even today that there are difficulties facing our families who are impacted by sickle cell disease, and they are related to structural racism and socioeconomic barriers,” Dr. Fasipe explained.

With these issues in mind, she said, “I refer to sickle cell disease as the medical representation of the Black experience in America.” However, she added, the good news is “we are now doing our best now to improve that.”

Among key efforts in building trust is the inclusion of patients with SCD and their families in as many aspects of research and clinical care as possible.

“In the global health care community, it is imperative to invite people with sickle cell disease and from the community to the decision-making table,” she noted.

“Now, when we’re talking about research for therapies, their expectation is that research trials and other initiatives for sickle cell disease must have input from the community; there are no initiatives for sickle cell disease that do not have input from the community.

“The patients and community members may not be experts on the science of sickle cell, but they’re experts on the lived experience and that’s very important when you’re thinking about new bringing in a new therapy.”
 

Forward momentum

Meanwhile, Dr. Fasipe observed, with the collective, advocacy-driven, forward momentum of the SCD community as a whole, things should only continue to improve.

“Because of the various barriers, some progress may not be immediately around the corner, but I do have confidence that this current generation of children with sickle cell will have improved health equity by the time they reach adulthood,” she said.

“I believe in this future, so I’m doing the work now, and it’s a promise I tell parents: I want your future adult child to live their best life, and we’re working hard to ensure that that becomes their future reality.”
 

Sickle cell disease awareness

September is National Sickle Cell Disease Awareness Month, and the National Heart, Lung, and Blood Institute offers a comprehensive website that clinicians can pass along to their patients, with information ranging from fact sheets on the disease and treatments to social media resources and inspiring stories of people with the disease.

In a comment, Lewis Hsu, MD, PhD, chief medical officer of the Sickle Cell Disease Association of America, underscored the uniquely important contributions of people like Dr. Fasipe, in providing inspiration to patients and clinicians alike.

“I have worked with several physicians, nurses, psychologists, and public health specialists who have sickle cell disease,” said Dr. Hsu, who is a pediatric hematologist who also serves as director of the Sickle Cell Center and professor of pediatrics for the University of Illinois at Chicago.

“They are ambassadors who have the trust of both patients and healthcare providers,” Dr. Hsu said.

In addition to providing inspiration of resilience, such care providers can serve as “communication bridges,” he explained.

“When they are conference speakers, everybody wants to hear them; when they sit on advisory committees or focus groups, they can help find the compromise or set the priorities.”

“Their impact on the whole sickle cell community is very large,” Dr. Hsu said.

Having grown up with sickle cell disease (SCD), Titilope Fasipe, MD, PhD, codirector of the sickle cell program at Texas Children’s Hospital in Houston, knows firsthand the physical pain, mental anguish, and dread that have long accompanied this condition. So few child patients lived to reach adulthood that until recently, SCD was considered a pediatric disease.

These days, thanks to transformative advances in treating SCD that have substantially improved survival, Dr. Fasipe’s mission for a new generation of patients and their families is to replace their pain and fear with relief and hope.

“If you grow up thinking that you’re going to die when you’re 18, it changes your world and your viewpoints, and it impacts your mental health,” she told this news organization.

“We are trying to make sure our children and their families know that there is a new story for sickle cell disease, and you don’t have to use any age as your prediction marker for your lifespan,” Dr. Fasipe said.

SCD, which affects about 100,000 people nationwide, is an inherited blood disorder, with the majority of patients – but not all – being of African descent. This condition is characterized by pain crises, or vaso-occlusive episodes, triggered when cells that are sickled get stuck and impede blood flow. These crises can come on suddenly and range from mild to severe.

Dr. Fasipe was born in Nigeria, where rates of SCD are among the world’s highest. She attended elementary school in the United States, where her father was studying theology, before returning to Nigeria with her family at age 11.

“Their impact on the whole sickle cell community is very large,” Dr. Hsu said.

A nationwide dearth of the specialists known as classical hematologists (CHs), who are trained to treat noncancerous bleeding disorders, has left many patients stranded and health care systems struggling to cope.

Over decades, the shrinking pool of CHs – who are compensated far less than hematologist-oncologists – has put patients at risk without access to adequate and timely care. To alleviate this crisis, individual doctors and national organizations are taking action and making more resources available to CHs and their patients.
 

`Vicious cycle’

The root cause of the CH shortage can be traced to a dramatic reduction in the number of physicians trained in this field, as Leonard Valentino, MD, President of the National Bleeding Disorders Foundation in New York, explained in an interview.

“There is a vicious cycle where there’s not enough classical hematologists to be program directors, and therefore trainees are often steered to fellowships in oncology,” said Dr. Valentino.

According to data published in JAMA, in 1995 there were 74 classical hematology programs in the United States; by 2018, there were only 2, During this same time period, the number of combined hematology/oncology training programs (HOPs) nearly doubled, from 75 to 146. However, it is estimated that less than 5% of graduates of adult HOPs pursued a career in classical hematology, as reported in Blood Advances. This low percentage can be attributed, at least in part, to the emphasis that most HOPs place on oncology.

Dr. Valentino noted that financial pressures are also diverting medical students from becoming CHs, adding that a hematologist-oncologist can make three times the annual salary of a CH.

Furthermore, when CHs treat bleeding and clotting disorders, they often need to meet with a patient for a 60- to 90-minute initial consultation, then they go on to provide a lifetime of labor-intensive care.

“This work is neither verticalized [that is, supported by radiologists, surgeons, and a cadre of nurses], nor is it billable per hour on a scale comparable to what oncologists can charge,” Dr. Valentino explained.

The survey published in Blood Advances illustrates the consequences of such a disparity in income potential: 34% of hematology/oncology fellows surveyed were likely to enter solid tumor oncology, while 20% and 4.6% would proceed to malignant hematology and CH, respectively.
 

Toll on patients

Primary care doctors treat some common blood disorders, but they almost always refer more difficult or complicated cases to a shrinking population of CHs.

Singal_Mukul_IN_web.jpg

“For many Americans, it is getting more difficult to find providers who subspecialize in hemostasis and thrombosis disorders. Patients can expect prolonged waiting times to get evaluated after a referral” said Mukul Singal, MD, of the Indiana Hemophilia and Thrombosis Center in Indianapolis.

Dr. Singal said the shortage is so acute that “at many institutions, malignant hematologists or oncologists are having to staff in-patient hematology consult services and see outpatient classical hematology patients. General hematologist/oncologists or medical oncologists are often not as comfortable or experienced with dealing with some of the complex CH conditions.”
 

A working care model, without enough doctors

In 1975, responding to patient advocacy groups, the federal government began funding hemophilia treatment centers (HTCs). Such centers offer a comprehensive care model that gives patients access to practitioners and administrative staff with the expertise to help them stay as healthy as possible. According to the Centers for Disease Control and Prevention, people with hemophilia who used an HTC were 40% less likely to die of a hemophilia-related complication and 40% less likely to be hospitalized for bleeding complications, compared to those who did not receive such specialized care.

“HTCs are effective at keeping patients out of the hospital and engaged in their lives. Between 80% and 95% of hemophilia patients get their care from an HTC and more patients want more services from them,” said Joe Pugliese, president of the Hemophilia Alliance in Lansdale, Pa.

Expanding care to meet patient demand is challenged by the restrictions on doctors’ salaries. All 140 U.S.-based HTCs share a $4.9 million federal grant but, by law, they can’t pay any provider more than $211,000 a year. “These restrictions push many people to industry, leaving too few doctors to meet patient demand,” Mr. Pugliese explained.

The fact that most HTCs are located in or near major cities also presents patients with the challenge of commuting, sometimes across state lines, to see a specialist. However, an uptick in telemedicine has provided one bright spot for many patients, allowing care to be brought to them.

The Hemophilia Alliance is also working on a multifaceted approach to change the rules, so that CHs are offered better compensation. “We have lobbyists in Washington, as well as an advocacy committee and a payer committee working to better support the HTC model,” Mr. Pugliese said.
 

Beyond the paycheck: Supporting CHs and patients

As market and regulatory restrictions make it difficult to boost the pay of CHs, doctors and nonprofit organizations are collaborating to support young CHs and bring more into the field. The American Society of Hematology has started and fully funded the Hematology Focused Fellowship Training Program (HFFTP). This program pairs comprehensive classical hematology training with education in transfusion medicine, sickle cell disease, hemostasis/thrombosis, systems-based hematology, health equity research, and global health. According to the program’s website, HFFTP’s goal is to add 50 new academic hematologists nationwide by 2030, in an effort to “improve the lives of patients with blood and bone marrow disorders.”

Additionally, classic hematologists are aiming to attract younger physicians and trainees to their field by introducing them to the various rewarding aspects of dealing with patients with inherited, chronic blood diseases. Programs like the Partners Physicians Academy (PPA), a 5-day training course that is specifically designed to encourage and retain young hematology students as classical hematologists, are essential to this effort.

“Along with preparing physicians to work in an HTC, programs like the Hematology Focused Fellowship Training Program and the Partners Physicians Academy are so important because they might convince young doctors to stick with non–oncology-based hematology careers, through the right mix of knowing about exciting research like gene therapy, financial and mentorship support, and a desire to meet unmet medical need,” explained Dr. Valentino.

The next PPA is taking place Sept. 18-22 in Indianapolis.

Dr. Singal, Dr. Valentino, and Mr. Pugliese had no financial disclosures to report.

A nationwide dearth of the specialists known as classical hematologists (CHs), who are trained to treat noncancerous bleeding disorders, has left many patients stranded and health care systems struggling to cope.

Over decades, the shrinking pool of CHs – who are compensated far less than hematologist-oncologists – has put patients at risk without access to adequate and timely care.

According to data published in JAMA, in 1995 there were 74 classical hematology programs in the United States; by 2018, there were only 2, During this same time period, the number of combined hematology/oncology training programs (HOPs) nearly doubled, from 75 to 146. However, it is estimated that less than 5% of graduates of adult HOPs pursued a career in classical hematology, as reported in Blood Advances. This low percentage can be attributed, at least in part, to the emphasis that most HOPs place on oncology.

Dr. Valentino noted that financial pressures are also diverting medical students from becoming CHs, adding that a hematologist-oncologist can make three times the annual salary of a CH.

Furthermore, when CHs treat bleeding and clotting disorders, they often need to meet with a patient for a 60- to 90-minute initial consultation, then they go on to provide a lifetime of labor-intensive care.

“This work is neither verticalized [that is, supported by radiologists, surgeons, and a cadre of nurses], nor is it billable per hour on a scale comparable to what oncologists can charge,” Dr. Valentino explained.

The survey published in Blood Advances illustrates the consequences of such a disparity in income potential: 34% of hematology/oncology fellows surveyed were likely to enter solid tumor oncology, while 20% and 4.6% would proceed to malignant hematology and CH, respectively.
 

Toll on patients

Primary care doctors treat some common blood disorders, but they almost always refer more difficult or complicated cases to a shrinking population of CHs.

“For many Americans, it is getting more difficult to find providers who subspecialize in hemostasis and thrombosis disorders. Patients can expect prolonged waiting times to get evaluated after a referral” said Mukul Singal, MD, of the Indiana Hemophilia and Thrombosis Center in Indianapolis.

Dr. Singal said the shortage is so acute that “at many institutions, malignant hematologists or oncologists are having to staff in-patient hematology consult services and see outpatient classical hematology patients. General hematologist/oncologists or medical oncologists are often not as comfortable or experienced with dealing with some of the complex CH conditions.”
 

A working care model, without enough doctors

In 1975, responding to patient advocacy groups, the federal government began funding hemophilia treatment centers (HTCs). Such centers offer a comprehensive care model that gives patients access to practitioners and administrative staff with the expertise to help them stay as healthy as possible. According to the Centers for Disease Control and Prevention, people with hemophilia who used an HTC were 40% less likely to die of a hemophilia-related complication and 40% less likely to be hospitalized for bleeding complications, compared to those who did not receive such specialized care.

“HTCs are effective at keeping patients out of the hospital and engaged in their lives. Between 80% and 95% of hemophilia patients get their care from an HTC and more patients want more services from them,” said Joe Pugliese, president of the Hemophilia Alliance in Lansdale, Pa.

Expanding care to meet patient demand is challenged by the restrictions on doctors’ salaries. All 140 U.S.-based HTCs share a $4.9 million federal grant but, by law, they can’t pay any provider more than $211,000 a year. “These restrictions push many people to industry, leaving too few doctors to meet patient demand,” Mr. Pugliese explained.

The fact that most HTCs are located in or near major cities also presents patients with the challenge of commuting, sometimes across state lines, to see a specialist. However, an uptick in telemedicine has provided one bright spot for many patients, allowing care to be brought to them.

The Hemophilia Alliance is also working on a multifaceted approach to change the rules, so that CHs are offered better compensation. “We have lobbyists in Washington, as well as an advocacy committee and a payer committee working to better support the HTC model,” Mr. Pugliese said.
 

Beyond the paycheck: Supporting CHs and patients

As market and regulatory restrictions make it difficult to boost the pay of CHs, doctors and nonprofit organizations are collaborating to support young CHs and bring more into the field. The American Society of Hematology has started and fully funded the Hematology Focused Fellowship Training Program (HFFTP). This program pairs comprehensive classical hematology training with education in transfusion medicine, sickle cell disease, hemostasis/thrombosis, systems-based hematology, health equity research, and global health. According to the program’s website, HFFTP’s goal is to add 50 new academic hematologists nationwide by 2030, in an effort to “improve the lives of patients with blood and bone marrow disorders.”

Additionally, classic hematologists are aiming to attract younger physicians and trainees to their field by introducing them to the various rewarding aspects of dealing with patients with inherited, chronic blood diseases. Programs like the Partners Physicians Academy (PPA), a 5-day training course that is specifically designed to encourage and retain young hematology students as classical hematologists, are essential to this effort.

“Along with preparing physicians to work in an HTC, programs like the Hematology Focused Fellowship Training Program and the Partners Physicians Academy are so important because they might convince young doctors to stick with non–oncology-based hematology careers, through the right mix of knowing about exciting research like gene therapy, financial and mentorship support, and a desire to meet unmet medical need,” explained Dr. Valentino.

The next PPA is taking place Sept. 18-22 in Indianapolis.

Dr. Singal, Dr. Valentino, and Mr. Pugliese had no financial disclosures to report.

A nationwide dearth of the specialists known as classical hematologists (CHs), who are trained to treat noncancerous bleeding disorders, has left many patients stranded and health care systems struggling to cope.

Over decades, the shrinking pool of CHs – who are compensated far less than hematologist-oncologists – has put patients at risk without access to adequate and timely care. To alleviate this crisis, individual doctors and national organizations are taking action and making more resources available to CHs and their patients.

Despite a growing list of Janus kinase (JAK) inhibitors, ruxolitinib remains the go-to for patients with symptomatic, higher risk myelofibrosis, according to Anthony M. Hunter, MD, a myeloid malignancies specialist at Emory University, Atlanta.

“We are thankfully starting to be blessed with more options than we’ve ever had,” he said, but “in the front-line proliferative setting, ruxolitinib has remained the standard of care.” It’s “well established in higher-risk patients and very much an option for very symptomatic lower-risk patients.”

Dr. Hunter helped his colleagues navigate the evolving field of JAK inhibition for myelofibrosis in a presentation titled “Choosing and Properly Using a JAK Inhibitor in Myelofibrosis,”at the Society of Hematologic Oncology annual meeting.

Ruxolitinib was the first JAK inhibitor for myelofibrosis on the U.S. market, approved in 2011. Two more have followed, fedratinib in 2019 and pacritinib in 2022.

A fourth JAK inhibitor for myelofibrosis, momelotinib, is under Food and Drug Administration review with a decision expected shortly.

JAK inhibitors disrupt a key pathogenic pathway in myelofibrosis and are a mainstay of treatment, but Dr. Hunter noted that they should not replace allogeneic transplants in patients who are candidates because transplants remain “the best way to achieve long term survival, especially in higher risk patients.”

He noted that not every patient needs a JAK inhibitor, especially “lower-risk, more asymptomatic patients who are predominantly manifesting with cytopenias. [They] are less likely to benefit.”

Dr. Hunter said that although ruxolitinib remains a treatment of choice, fedratinib “is certainly an option” with comparable rates of symptom control and splenomegaly reduction. Also, while ruxolitinib is dosed according to platelet levels, fedratinib allows for full dosing down to a platelet count of 50 x 10⁹/L.

“But there’s more GI toxicity than with ruxolitinib, especially in the first couple of months,” he said, as well as a black box warning of Wernicke’s encephalopathy. “I generally put all my [fedratinib] patients on thiamine repletion as a precaution.”

One of the most challenging aspects of using JAK inhibitors for myelofibrosis is their tendency to cause cytopenia, particularly anemia and thrombocytopenia, which, ironically, are also hallmarks of myelofibrosis itself.

Although there’s an alternative low-dose ruxolitinib regimen that can be effective in anemic settings, the approval of pacritinib and most likely momelotinib is particularly helpful for cytopenic patients, “a population which historically has been very hard to treat with our prior agents,” Dr. Hunter said.

Pacritinib is approved specifically for patients with platelet counts below 50 x 10⁹/L; momelotinib also included lower platelet counts in several studies. Both agents indirectly boost erythropoiesis with subsequent amelioration of anemia.

“Momelotinib is an important emerging agent for these more anemic patients,” with a spleen response comparable to ruxolitinib and significantly higher rates of transfusion independence, but with lower rates of symptom control, Dr. Hunter said.

Pacritinib “really helps extend the benefit of JAK inhibitors to a group of thrombocytopenic patients who have been hard to treat with ruxolitinib,” with the added potential of improving anemia, although, like fedratinib, it has more GI toxicity, he said.

There are multiple add-on options for JAK inhibitor patients with anemia, including luspatercept, an erythropoiesis-stimulating agent approved for anemia in patients with myelodysplastic syndromes; promising results were reported recently for myelofibrosis.

Fedratinib, pacritinib, and momelotinib all have activity in the second line after ruxolitinib failure, Dr. Hunter noted, but he cautioned that ruxolitinib must be tapered over a few weeks, not stopped abruptly, to avoid withdrawal symptoms. Some clinicians overlap JAK inhibitors a day or two to avoid issues.

“Clinical trials should still be considered in many of these settings,” he said, adding that emerging agents are under development, including multiple combination therapies, often with JAK inhibitors as the background.
