An international survey provides new insights into how COVID-19 has affected, and may continue to affect, the field of oncology.

The survey showed that “COVID-19 has had a major impact on the organization of patient care, on the well-being of caregivers, on continued medical education, and on clinical trial activities in oncology,” stated Guy Jerusalem, MD, PhD, of Centre Hospitalier Universitaire de Liège (Belgium).

Dr. Jerusalem presented these findings at the European Society for Medical Oncology Virtual Congress 2020.

The survey was distributed by 20 oncologists from 10 of the countries most affected by COVID-19. Responses were obtained from 109 oncologists representing centers in 18 countries. The responses were recorded between June 17 and July 14, 2020.

The survey consisted of 95 items intended to evaluate the impact of COVID-19 on the organization of oncologic care. Questions encompassed the capacity and service offered at each center, the magnitude of COVID-19–based care interruptions and the reasons for them, the ensuing challenges faced, interventions implemented, and the estimated harms to patients during the pandemic.

The 109 oncologists surveyed had a median of 20 years of oncology experience. A majority of respondents were men (61.5%), and the median age was 48.5 years.

The respondents had worked predominantly (62.4%) at academic hospitals, with 29.6% at community hospitals. Most respondents worked at general hospitals with an oncology unit (66.1%) rather than a specialized separate cancer center (32.1%).

The most common specialty was breast cancer (60.6%), followed by gastrointestinal cancer (10.1%), urogenital cancer (9.2%), and lung cancer (8.3%).
 

Impact on treatment

The treatment modalities affected by the pandemic – through cancellations or delays in more than 10% of patients – included surgery (in 34% of centers), chemotherapy (22%), radiotherapy (13.7%), checkpoint inhibitor therapy (9.1%), monoclonal antibodies (9%), and oral targeted therapy (3.7%).

Among oncologists treating breast cancer, cancellations/delays in more than 10% of patients were reported for everolimus (18%), CDK4/6 inhibitors (8.9%), and endocrine therapy (2.2%).

Overall, 34.8% of respondents reported increased use of granulocyte colony–stimulating factor, and 6.4% reported increased use of erythropoietin.

On the other hand, 11.1% of respondents reported a decrease in the use of double immunotherapy, and 21.9% reported decreased use of corticosteroids.

Not only can the immunosuppressive effects of steroid use increase infection risks, Dr. Jerusalem noted, fever suppression can lead to a delayed diagnosis of COVID-19.

“To circumvent potential higher infection risks or greater disease severity, we use lower doses of steroids, but this is not based on studies,” he said.

“Previous exposure to steroids or being on steroids at the time of COVID-19 infection is a detrimental factor for complications and mortality,” commented ESMO President Solange Peters, MD, PhD, of Centre Hospitalier Universitaire Vaudois in Lausanne, Switzerland.

Dr. Peters noted that the observation was based on lung cancer registry findings. Furthermore, because data from smaller outbreaks of other coronavirus infections suggested worse prognosis and increased mortality, steroid use was already feared in the very early days of the COVID-19 pandemic.

Lastly, earlier cessation of palliative treatment was observed in 32.1% of centers, and 64.2% of respondents agreed that undertreatment because of COVID-19 is a major concern.

Dr. Jerusalem noted that the survey data do not explain the early cessation of palliative treatment. “I suspect that many patients died at home rather than alone in institutions because it was the only way they could die with their families around them.”
 

Telehealth, meetings, and trials

The survey also revealed rationales for the use of teleconsultation, including follow-up (94.5%), oral therapy (92.7%), immunotherapy (57.8%), and chemotherapy (55%).

Most respondents reported more frequent use of virtual meetings for continuing medical education (94%), oncologic team meetings (92%), and tumor boards (82%).

While about 82% of respondents said they were likely to continue the use of telemedicine, 45% said virtual conferences are not an acceptable alternative to live international conferences such as ESMO, Dr. Jerusalem said.

Finally, nearly three-quarters of respondents (72.5%) said all clinical trial activities are or will soon be activated, or never stopped, at their centers. On the other hand, 27.5% of respondents reported that their centers had major protocol violations or deviations, and 37% of respondents said they expect significant reductions in clinical trial activities this year.

Dr. Jerusalem concluded that COVID-19 is having a major, long-term impact on the organization of patient care, caregivers, continued medical education, and clinical trial activities in oncology.

He cautioned that “the risk of a delayed diagnosis of new cancers and economic consequences of COVID-19 on access to health care and cancer treatments have to be carefully evaluated.”

This research was funded by Fondation Léon Fredericq. Dr. Jerusalem disclosed relationships with Novartis, Roche, Lilly, Pfizer, Amgen, Bristol-Myers Squibb, AstraZeneca, Daiichi Sankyo, AbbVie, MedImmune, and Merck. Dr. Peters disclosed relationships with AbbVie, Amgen, AstraZeneca, and many other companies.

In its updated cancer prevention guidelines, the American Cancer Society now recommends that “it is best not to drink alcohol.”

Previously, ACS suggested that, for those who consume alcoholic beverages, intake should be no more than one drink per day for women or two per day for men. That recommendation is still in place, but is now accompanied by this new, stronger directive.

The revised guidelines also place more emphasis on reducing the consumption of processed and red meat and highly processed foods, and on increasing physical activity.

But importantly, there is also a call for action from public, private, and community organizations to work to together to increase access to affordable, nutritious foods and physical activity.

“Making healthy choices can be challenging for many, and there are strategies included in the guidelines that communities can undertake to help reduce barriers to eating well and physical activity,” said Laura Makaroff, DO, American Cancer Society senior vice president. “Individual choice is an important part of a healthy lifestyle, but having the right policies and environmental factors to break down these barriers is also important, and that is something that clinicians can support.”

The guidelines were published in CA: A Cancer Journal for Clinicians.

The link between cancer and lifestyle factors has long been established, and for the past 4 decades, both government and leading nonprofit health organizations, including the ACS and the World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR), have released cancer prevention guidelines and recommendations that focus on managing weight, diet, physical activity, and alcohol consumption.

In 2012, the ACS issued guidelines on diet and physical activity, and their current guideline is largely based on the WCRF/AICR systematic reviews and Continuous Update Project reports, which were last updated in 2018. The ACS guidelines also incorporated systematic reviews conducted by the International Agency on Cancer Research (IARC) and the U.S. Department of Agriculture and the Department of Health and Human Services (USDA/HHS) and other analyses that were published since the WCRF/AICR recommendations were released.
 

Emphasis on three areas

The differences between the old guidelines and the update do not differ dramatically, but Makaroff highlighted a few areas that have increased emphasis.

Time spent being physically active is critical. The recommendation has changed to encourage adults to engage in 150-300 minutes (2.5-5 hours) of moderate-intensity physical activity, or 75-150 minutes (1.25-2.5 hours) of vigorous-intensity physical activity, or an equivalent combination, per week. Achieving or exceeding the upper limit of 300 minutes is optimal.

“That is more than what we have recommended in the past, along with the continued message that children and adolescents engage in at least 1 hour of moderate- or vigorous-intensity activity each day,” she told Medscape Medical News.

The ACS has also increased emphasis on reducing the consumption of processed and red meat. “This is part of a healthy eating pattern and making sure that people are eating food that is high in nutrients that help achieve and maintain a healthy body weight,” said Makaroff.

A healthy diet should include a variety of dark green, red, and orange vegetables; fiber-rich legumes; and fruits with a variety of colors and whole grains, according to the guidelines. Sugar-sweetened beverages, highly processed foods, and refined grain products should be limited or avoided.

The revised dietary recommendations reflect a shift from a “reductionist or nutrient-centric” approach to one that is more “holistic” and that focuses on dietary patterns. In contrast to a focus on individual nutrients and bioactive compounds, the new approach is more consistent with what and how people actually eat, ACS points out.

The third area that Makaroff highlighted is alcohol, where the recommendation is to avoid or limit consumption. “The current update says not to drink alcohol, which is in line with the scientific evidence, but for those people who choose to drink alcohol, to limit it to one drink per day for women and two drinks per day for men.”

Thus, the change here is that the previous guideline only recommended limiting alcohol consumption, while the update suggests that, optimally, it should be avoided completely.

The ACS has also called for community involvement to help implement these goals: “Public, private, and community organizations should work collaboratively at national, state, and local levels to develop, advocate for, and implement policy and environmental changes that increase access to affordable, nutritious foods; provide safe, enjoyable, and accessible opportunities for physical activity; and limit alcohol for all individuals.”
 

No smoking guns

Commenting on the guidelines, Steven K. Clinton, MD, PhD, associate director of the Center for Advanced Functional Foods Research and Entrepreneurship at the Ohio State University, Columbus, explained that he didn’t view the change in alcohol as that much of an evolution. “It’s been 8 years since they revised their overall guidelines, and during that time frame, there has been an enormous growth in the evidence that has been used by many organizations,” he said.

Clinton noted that the guidelines are consistent with the whole body of current scientific literature. “It’s very easy to go to the document and look for the ‘smoking gun’ – but the smoking gun is really not one thing,” he said. “It’s a pattern, and what dietitians and nutritionists are telling people is that you need to orchestrate a healthy lifestyle and diet, with a diet that has a foundation of fruits, vegetables, whole grains, and modest intake of refined grains and meat. You are orchestrating an entire pattern to get the maximum benefit.”

Makaroff is an employee of the ACS. Clinton has disclosed no relevant financial relationships.

The American Society of Hematology has committed a portion of its website to providing continually updated information addressing specific hematologic disorders in relation to COVID-19.

“As the world grapples with the novel coronavirus, ASH believes that we can help each other be as knowledgeable and prepared as possible,” wrote the society’s president, Stephanie J. Lee, MD, MPH.

On its website, ASH provides relevant COVID-19 information in a series of FAQ divided into malignant and nonmalignant hematologic diseases and disorders. In the malignant category, the various lymphomas and leukemias are individually addressed, as well as other conditions such as myelodysplastic syndromes, myeloproliferative neoplasms, and multiple myeloma. In the nonmalignant category, ASH has provided FAQ on aplastic anemia, thalassemia, sickle cell disease, pulmonary embolism, venous thromboembolism/anticoagulation, coagulopathy, and immune as well as thrombotic thrombocytopenic purpura.

In addition to the continually updated series of relevant FAQ, as part of its response to the pandemic ASH is promoting two unique COVID-19 registries for physicians: the ASH Research Collaborative’s (ASH RC) Data Hub COVID-19 Registry and the Surveillance Epidemiology of Coronavirus (COVID-19) Under Research Exclusion Sickle Cell Disease (SECURE-SCD) Registry.

“The ASH Research Collaborative’s (ASH RC) Data Hub launched the COVID-19 Registry and is currently capturing data on people who test positive for COVID-19 and have been or are currently being treated for hematologic malignancy,” according to the website. The intention is to provide “near real-time observational data summaries,” which will hopefully provide useful information to clinicians treating hematologic malignancies in patients in the midst of the COVID-19 pandemic.

The registry allows clinicians to enter their own cases in a specified format to allow data analysis on clinical practice and patient outcomes that will be aggregated to provide rapid insights for clinicians to help them care for their patients, according to ASH.

The second registry specifically deals with COVID-19 cases in patients with sickle cell disease. It also allows clinicians to add cases with a similar intention of aggregating data to provide near real-time insights into patient care. “We are asking providers caring for these patients to report all of their cases of COVID-19 to this registry,” according to the registry website. The registry is for reporting COVID-19 cases in sickle cell disease patients “after sufficient time has passed to observe the disease course through resolution of acute illness and/or death.”

ASH also provides more generalized information for hematology practitioners dealing with COVID-19 on the topics of conducting their practice and using telemedicine, among others.

The American Society of Hematology has committed a portion of its website to providing continually updated information addressing specific hematologic disorders in relation to COVID-19.

“As the world grapples with the novel coronavirus, ASH believes that we can help each other be as knowledgeable and prepared as possible,” wrote the society’s president, Stephanie J. Lee, MD, MPH.

On its website, ASH provides relevant COVID-19 information in a series of FAQ divided into malignant and nonmalignant hematologic diseases and disorders. In the malignant category, the various lymphomas and leukemias are individually addressed, as well as other conditions such as myelodysplastic syndromes, myeloproliferative neoplasms, and multiple myeloma. In the nonmalignant category, ASH has provided FAQ on aplastic anemia, thalassemia, sickle cell disease, pulmonary embolism, venous thromboembolism/anticoagulation, coagulopathy, and immune as well as thrombotic thrombocytopenic purpura.

In addition to the continually updated series of relevant FAQ, as part of its response to the pandemic ASH is promoting two unique COVID-19 registries for physicians: the ASH Research Collaborative’s (ASH RC) Data Hub COVID-19 Registry and the Surveillance Epidemiology of Coronavirus (COVID-19) Under Research Exclusion Sickle Cell Disease (SECURE-SCD) Registry.

“The ASH Research Collaborative’s (ASH RC) Data Hub launched the COVID-19 Registry and is currently capturing data on people who test positive for COVID-19 and have been or are currently being treated for hematologic malignancy,” according to the website. The intention is to provide “near real-time observational data summaries,” which will hopefully provide useful information to clinicians treating hematologic malignancies in patients in the midst of the COVID-19 pandemic.

The registry allows clinicians to enter their own cases in a specified format to allow data analysis on clinical practice and patient outcomes that will be aggregated to provide rapid insights for clinicians to help them care for their patients, according to ASH.

The second registry specifically deals with COVID-19 cases in patients with sickle cell disease. It also allows clinicians to add cases with a similar intention of aggregating data to provide near real-time insights into patient care. “We are asking providers caring for these patients to report all of their cases of COVID-19 to this registry,” according to the registry website. The registry is for reporting COVID-19 cases in sickle cell disease patients “after sufficient time has passed to observe the disease course through resolution of acute illness and/or death.”

ASH also provides more generalized information for hematology practitioners dealing with COVID-19 on the topics of conducting their practice and using telemedicine, among others.

Absolute lymphocyte cell (ALC) and absolute monocyte cell (AMC) counts, as well as their ratio (LMR) proved to be prognostic factors for treatment results, as shown by a database analysis of follicular lymphoma (FL) patients.

Progressive disease and stable disease after first-line therapy, as well as the mortality rate, were significantly associated with lower ALC, higher AMC, and higher LMR, according to the report published online.

Researchers analyzed the data of 100 FL variant patients admitted and treated between January 2009 and June 2018 at a single center.

Area under the curve analysis for discriminating between survival times showed 0.57 x 10⁹ cells/L was the most discriminative ALC cutoff value, 1.24 x 10⁹/L was the most discriminative AMC cutoff value, and 1.63 x 10⁹/L was the most discriminative LMR cutoff value.

Shorter overall survival (OS) was significantly associated with lower ALC, compared with those having higher ALC. Shorter OS and progression-free survival (PFS) were significantly associated with higher AMC, compared with those having lower AMC. Shorter OS and PFS were also significantly associated with lower LMR, compared with those having higher LMR.

Overall, a high-risk score in the Follicular Lymphoma International Prognostic Index (FLIPI) and having a low LMR were considered risk factors for prediction of OS in all the studied FL patients in univariate analysis and multivariate analysis, according to the researchers.

“Our results prove the effect of lymphocyte and monocyte in the tumor immune response, which gives opportunity to several therapeutic strategies that target myeloid-derived suppressor cells (MDSCs), including monocytes and their progeny and improves the T-cell function in eradication strategies,” the researchers concluded.

LAHAINA, HAWAII – General dermatologists can have a high degree of confidence in treating patients with stage I mycosis fungoides without bringing in a medical oncologist, Trilokraj Tejasvi, MBBS, said at the Hawaii Dermatology Seminar provided by Global Academy for Medical Education/Skin Disease Education Foundation.

Bruce Jancin/MDedge News

This approach is in the best interest of patients with stage I mycosis fungoides, the skin-limited, patch/plaque form of the disease that generally responds well to skin-directed therapies without needing to resort to the medical oncologist’s arsenal of toxic treatments.

“For many medical oncologists, a lymphoma is a lymphoma. The first thing they give is CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone), and all the variants of CHOP,” cautioned Dr. Tejasvi, a dermatologist who is director of the cutaneous lymphoma program at the University of Michigan, Ann Arbor, and chief of the dermatology service at the Ann Arbor Veteran Affairs Hospital.

Stage IA mycosis fungoides is defined under the TNMB (tumor, node, metastasis, blood) classification as patches and/or plaques covering less than 10% of body surface area along with negative nodes, no metastases, and no or low burden of disease in the blood. Stage IB differs only in that it features 10% or greater body surface area involvement. The extent of body surface area involvement can be estimated by hands-on measurement in which the area of one of the patient’s hands – palm plus fingers – is considered equivalent to 1% of that individual’s total body surface area.

The first question patients newly diagnosed with a cutaneous T-cell lymphoma ask concerns their prognosis. For those with stage IA or IB mycosis fungoides, the news is very good, as highlighted in a retrospective study of nearly 1,400 patients with mycosis fungoides, 71% of whom presented with patch/plaque stage disease (J Clin Oncol. 2010 Nov 1;28[31]:4730-9).

The median overall survival was 35.5 years in patients with stage IA disease and 21.5 years in those with stage IB disease.

“I tell patients with stage IA disease that whether we treat it or not will not change the course of their life,” Dr. Tejasvri said.

His message to patients with stage IB disease is that, because of their 38% risk of disease progression, he wants to see them in follow-up annually for the rest of their life.

Stage IIA disease – that is, patches and/or plaques with lymph node involvement with no effacement – is a tipping point at which serious consideration should be given to possible referral to a specialized multidisciplinary lymphoma center, in his view. That’s because the 10-year overall survival rate is only 52%.

Topical therapies

Topical corticosteroids remain the time-honored first-line skin-directed treatment. The mechanism of benefit involves induction of apoptosis and inhibition of lymphocyte binding. In one prospective study, clobetasol propionate achieved a 94% overall response rate in patients with stage IA or B disease, with minimal toxicity.

Alternatives include topical 5% imiquimod (Aldara), with an overall response rate of 80% and complete response rate of 45% in a 20-patient study. A newer formulation of mechlorethamine gel (Valchlor), is reported to have a 59% overall response rate and a sustained response in 86% of initial responders. For refractory skin lesions, 1% bexarotene gel (Targretin) is an option, with overall response rates of 44%-63% reported in prospective trials.

“I like it if the patient’s insurance covers it. Otherwise, it’s like buying a Prius: it’s $30,000 for a 45-g tube, which is insane,” Dr. Tejasvi commented.

Narrow-band UVB phototherapy is an effective modality for thin plaques and patches, as is PUVA for thicker ones. Dr. Tejasvi typically treats with topical steroids and/or phototherapy for at least 3 months before tapering.

When to suspect mycosis fungoides

“Mycosis fungoides is a great masquerader,” the dermatologist observed. For that reason, it deserves to be included in the differential diagnosis of an atypical psoriasiform or eczematoid rash, any new-onset rash in an elderly patient, or a rash with fever, night sweats, and unintended weight loss in a patient of any age. Generalized erythema with severe itching is another red flag.

“This pruritus is so severe that the only other condition which in my clinical practice would match it is Norwegian scabies,” according to Dr. Tejasvi.

Polychromatic patches or plaques in skin of color warrant further investigation as possible mycosis fungoides, he added.

Dr. Tejasvi reported having no financial conflicts of interest regarding his presentation.

ORLANDO – Anti-CD5 chimeric antigen receptor (CAR) T cells can produce complete responses (CRs) in patients with relapsed or refractory T-cell malignancies, according to findings from a phase 1 trial.

Jennifer Smith/MDedge News

Three of 11 patients achieved a CR after CAR T-cell therapy, and one patient achieved a mixed response that deepened to a CR after transplant. Three responders, all of whom had T-cell lymphoma, were still alive and in CR at last follow-up.

There were no cases of severe cytokine release syndrome (CRS) or severe neurotoxicity, no serious infectious complications, and no nonhematologic grade 4 adverse events in this trial.

LaQuisa C. Hill, MD, of Baylor College of Medicine, Houston, presented these results at the annual meeting of the American Society of Hematology.

“While CD19 CAR T cells have revolutionized the treatment of relapsed/refractory B-cell malignancies, development of CAR T-cell platforms targeting T-cell-driven malignancies have been hindered by three main factors: CAR T-cell fratricide due to shared expression of target antigens leading to impaired expansion, ablation of normal T cells continuing to cause profound immunodeficiency, and the potential of transduced tumor cells providing a means of tumor escape,” Dr. Hill said.

Researchers have theorized that anti-CD5 CAR T cells can overcome these obstacles. In preclinical studies, anti-CD5 CAR T cells eliminated malignant blasts in vitro and in vivo and resulted in “limited and transient” fratricide (Blood. 2015 Aug 20;126[8]:983-92).

With this in mind, Dr. Hill and her colleagues tested CD5.28z CAR T cells in a phase 1 trial (NCT03081910). Eleven patients have been treated thus far – five with T-cell acute lymphoblastic leukemia (T-ALL), three with peripheral T-cell lymphoma (PTCL), two with angioimmunoblastic T-cell lymphoma (AITL), and one with Sézary syndrome.

The patients’ median age at baseline was 62 years (range, 21-71 years), and 63% were men. They had received a median of 5 prior therapies (range, 3-18). Two patients had relapsed after allogeneic hematopoietic stem cell transplant (HSCT), three had relapsed after autologous HSCT, and five were primary refractory.

Patients underwent lymphodepletion with fludarabine and cyclophosphamide, then received CAR T cells at doses of 1 x 10⁷ or 5 x 10⁷.
 

Response

Three lymphoma patients – two with AITL and one with PTCL – were still alive and in CR at last follow-up. The PTCL patient achieved a CR after CAR T-cell therapy and declined a subsequent HSCT. The patient has not received additional therapy and has retained the CR for 7 months.

One AITL patient achieved a CR and declined transplant as well. He relapsed after 7 months but received subsequent therapy and achieved another CR. The other AITL patient had a mixed response to CAR T-cell therapy but proceeded to allogeneic HSCT and achieved a CR that has lasted 9 months.

The remaining three lymphoma patients – two with PTCL and one with Sézary syndrome – progressed and died.

One T-ALL patient achieved a CR lasting 6 weeks, but the patient died while undergoing transplant workup. Two T-ALL patients did not respond to treatment and died. The remaining two patients progressed, and one of them died. The other patient who progressed is still alive and in CR after receiving subsequent therapy.

Factors associated with response

Dr. Hill said a shortened manufacturing process may be associated with enhanced response, as all responders received CAR T cells produced via a shorter manufacturing process. The shortened process involves freezing cells on day 4-5 post transduction, as opposed to day 7.

“While the numbers are too small to make any definitive conclusions, this seems to correlate with less terminal differentiation, which might improve potency,” Dr. Hill said. “However, additional analyses are ongoing.”

Dr. Hill also pointed out that CAR T-cell expansion was observed in all patients, with higher peak levels observed at the higher dose. In addition, CAR T-cell persistence was durable at both dose levels.

“We have been able to detect the CAR transgene at all follow-up time points, out to 9 months for some patients,” Dr. Hill said. “While limited persistence may play a role in nonresponders, it does not appear to be the only factor.”

Safety

“Surprisingly, no selective ablation of normal T cells has been observed,” Dr. Hill said. “As CAR T cells dwindled [after infusion], we were able to see recovery of normal T cells, all of which expressed normal levels of CD5. This was observed in all patients on study, except for one patient who had prolonged pancytopenia.”

Cytopenias were the most common grade 3/4 adverse events, including neutropenia (n = 8), anemia (n = 7), and thrombocytopenia (n = 5). Other grade 3/4 events included elevated aspartate aminotransferase (n = 2), hypoalbuminemia (n = 1), hyponatremia (n = 1), hypophosphatemia (n = 1), and elevated alanine aminotransferase (n = 1). There were no grade 5 adverse events.

Two patients developed grade 1 CRS, and two had grade 2 CRS. Both patients with grade 2 CRS were treated with tocilizumab, and their symptoms resolved.

One patient developed grade 2 immune effector cell-associated neurotoxicity syndrome, but this resolved with supportive care.

One patient had a central line–associated bloodstream infection (coagulase-negative staphylococci), and one had cytomegalovirus and BK virus reactivation. There were no fungal infections.

“We have demonstrated that CD5 CAR T cells can be manufactured from heavily pretreated patients with T-cell malignancies, and therapy is well tolerated,” Dr. Hill said. “We have seen strong and promising activity in T-cell lymphoma, which we hope to be able to translate to T-ALL as well.”

Dr. Hill said she and her colleagues hope to improve upon these results with a higher dose level of CD5 CAR T cells (1 x 10⁸), which the team plans to start testing soon. The researchers may also investigate other target antigens, such as CD7, as well as the use of donor-derived CAR T cells for patients who have relapsed after allogeneic HSCT.

Dr. Hill said she has no relevant disclosures. Baylor College of Medicine is sponsoring this trial.

The patients’ median age at baseline was 62 years (range, 21-71 years), and 63% were men. They had received a median of 5 prior therapies (range, 3-18). Two patients had relapsed after allogeneic hematopoietic stem cell transplant (HSCT), three had relapsed after autologous HSCT, and five were primary refractory.

Patients underwent lymphodepletion with fludarabine and cyclophosphamide, then received CAR T cells at doses of 1 x 10⁷ or 5 x 10⁷.
 

Response

Three lymphoma patients – two with AITL and one with PTCL – were still alive and in CR at last follow-up. The PTCL patient achieved a CR after CAR T-cell therapy and declined a subsequent HSCT. The patient has not received additional therapy and has retained the CR for 7 months.

One AITL patient achieved a CR and declined transplant as well. He relapsed after 7 months but received subsequent therapy and achieved another CR. The other AITL patient had a mixed response to CAR T-cell therapy but proceeded to allogeneic HSCT and achieved a CR that has lasted 9 months.

The remaining three lymphoma patients – two with PTCL and one with Sézary syndrome – progressed and died.

One T-ALL patient achieved a CR lasting 6 weeks, but the patient died while undergoing transplant workup. Two T-ALL patients did not respond to treatment and died. The remaining two patients progressed, and one of them died. The other patient who progressed is still alive and in CR after receiving subsequent therapy.

Factors associated with response

Dr. Hill said a shortened manufacturing process may be associated with enhanced response, as all responders received CAR T cells produced via a shorter manufacturing process. The shortened process involves freezing cells on day 4-5 post transduction, as opposed to day 7.

“While the numbers are too small to make any definitive conclusions, this seems to correlate with less terminal differentiation, which might improve potency,” Dr. Hill said. “However, additional analyses are ongoing.”

Dr. Hill also pointed out that CAR T-cell expansion was observed in all patients, with higher peak levels observed at the higher dose. In addition, CAR T-cell persistence was durable at both dose levels.

“We have been able to detect the CAR transgene at all follow-up time points, out to 9 months for some patients,” Dr. Hill said. “While limited persistence may play a role in nonresponders, it does not appear to be the only factor.”

Safety

“Surprisingly, no selective ablation of normal T cells has been observed,” Dr. Hill said. “As CAR T cells dwindled [after infusion], we were able to see recovery of normal T cells, all of which expressed normal levels of CD5. This was observed in all patients on study, except for one patient who had prolonged pancytopenia.”

Cytopenias were the most common grade 3/4 adverse events, including neutropenia (n = 8), anemia (n = 7), and thrombocytopenia (n = 5). Other grade 3/4 events included elevated aspartate aminotransferase (n = 2), hypoalbuminemia (n = 1), hyponatremia (n = 1), hypophosphatemia (n = 1), and elevated alanine aminotransferase (n = 1). There were no grade 5 adverse events.

Two patients developed grade 1 CRS, and two had grade 2 CRS. Both patients with grade 2 CRS were treated with tocilizumab, and their symptoms resolved.

One patient developed grade 2 immune effector cell-associated neurotoxicity syndrome, but this resolved with supportive care.

One patient had a central line–associated bloodstream infection (coagulase-negative staphylococci), and one had cytomegalovirus and BK virus reactivation. There were no fungal infections.

“We have demonstrated that CD5 CAR T cells can be manufactured from heavily pretreated patients with T-cell malignancies, and therapy is well tolerated,” Dr. Hill said. “We have seen strong and promising activity in T-cell lymphoma, which we hope to be able to translate to T-ALL as well.”

Dr. Hill said she and her colleagues hope to improve upon these results with a higher dose level of CD5 CAR T cells (1 x 10⁸), which the team plans to start testing soon. The researchers may also investigate other target antigens, such as CD7, as well as the use of donor-derived CAR T cells for patients who have relapsed after allogeneic HSCT.

Dr. Hill said she has no relevant disclosures. Baylor College of Medicine is sponsoring this trial.

ORLANDO – Anti-CD5 chimeric antigen receptor (CAR) T cells can produce complete responses (CRs) in patients with relapsed or refractory T-cell malignancies, according to findings from a phase 1 trial.

Jennifer Smith/MDedge News

Three of 11 patients achieved a CR after CAR T-cell therapy, and one patient achieved a mixed response that deepened to a CR after transplant. Three responders, all of whom had T-cell lymphoma, were still alive and in CR at last follow-up.

There were no cases of severe cytokine release syndrome (CRS) or severe neurotoxicity, no serious infectious complications, and no nonhematologic grade 4 adverse events in this trial.

LaQuisa C. Hill, MD, of Baylor College of Medicine, Houston, presented these results at the annual meeting of the American Society of Hematology.

“While CD19 CAR T cells have revolutionized the treatment of relapsed/refractory B-cell malignancies, development of CAR T-cell platforms targeting T-cell-driven malignancies have been hindered by three main factors: CAR T-cell fratricide due to shared expression of target antigens leading to impaired expansion, ablation of normal T cells continuing to cause profound immunodeficiency, and the potential of transduced tumor cells providing a means of tumor escape,” Dr. Hill said.

Researchers have theorized that anti-CD5 CAR T cells can overcome these obstacles. In preclinical studies, anti-CD5 CAR T cells eliminated malignant blasts in vitro and in vivo and resulted in “limited and transient” fratricide (Blood. 2015 Aug 20;126[8]:983-92).

With this in mind, Dr. Hill and her colleagues tested CD5.28z CAR T cells in a phase 1 trial (NCT03081910). Eleven patients have been treated thus far – five with T-cell acute lymphoblastic leukemia (T-ALL), three with peripheral T-cell lymphoma (PTCL), two with angioimmunoblastic T-cell lymphoma (AITL), and one with Sézary syndrome.

ORLANDO – There is an urgent need for new therapies to treat relapsed or refractory peripheral T-cell lymphoma, but results of a phase 2 study suggest that monotherapy with the immune checkpoint inhibitor nivolumab (Opdivo) is not the hoped-for salvage treatment.

Neil Osterweil/MDedge News

An interim analysis of data on 12 patients with peripheral T-cell lymphoma (PTCL) treated with nivolumab monotherapy showed an overall response rate of 33%, consisting of 2 complete responses and 2 partial responses. But the responses were short lived, and one patient had hyperprogressive disease – dramatic progression within one cycle of treatment – while two more had progression within two cycles, leading to a trial halt, reported N. Nora Bennani, MD, from the Mayo Clinic in Rochester, Minn.

“These findings likely reflect the distinct biology of PTCL and should be considered when designing future studies using checkpoint inhibitors in these diseases,” she said at the annual meeting of the American Society of Hematology.

The rationale for using an immune checkpoint inhibitor directed against the programmed death–1 protein and its ligands (PD and PD-L1/2) is that malignant cells in PTCL induce a profoundly immunosuppressive tumor microenvironment. Checkpoint inhibitors have shown strong activity against relapsed Hodgkin lymphoma, and the Mayo Clinic researchers speculated that an anti-PD-1 agent could have a similar effect in PTCL.

They had originally planned to enroll 29 patients into a phase 2 trial with nivolumab delivered 240 mg every 2 weeks for eight cycles, followed by a dose of 480 mg given every 4 weeks until disease progression or intolerable toxicities.

Patients were eligible if they had biopsy-confirmed relapsed or refractory PTCL, measurable disease on cross-sectional imaging of at least 1.5 cm, and prior systemic chemoimmunotherapy and/or autologous stem cell transplantation.

The interim analysis included 12 patients who received at least one dose of nivolumab. Of the 12 patients, 6 had angioimmunoblastic T-cell lymphoma (AITL), 3 had PTCL not otherwise specified, and 1 each had ALK-negative anaplastic large cell lymphoma (ALK-ALCL), enteropathy-associated T-cell lymphoma (EATL), or hepatosplenic gamma/delta T-cell lymphoma.

All patients had Ann Arbor stage III/IV disease, and 11 had extranodal involvement.

As noted, there were 4 responses among the 12 patients, consisting of 1 complete response in the patient with ALK-ALCL and 1 in a patient with AITL, and 2 partial responses – 1 in a patient with PTCL-NOS, and 1 in the patient with EATL.

The median progression-free survival for all 12 patients was short at 2.7 months, and the median overall survival was estimated at 6.7 months.

“It was staggering to see this: The duration of response was significantly short, less than 2 months,” Dr. Bennani said.

Nonhematologic toxicities were seen in 5 of the 12 patients (42%), and hematologic adverse events occurred in 3 (25%). All patients are now off treatment, 10 because of disease progression, 1 because of acute pancreatitis, and the aforementioned patient with hyperprogressive disease.

The patient with hyperprogressive disease had significant progression in tonsillar and cervical lymphadenopathy within 7-10 days of nivolumab infusion, with biopsy-proven AITL in the involved nodes.

“I believe that, in this patient population, combination therapies will be key. I think checkpoint blockers alone are not going to be sufficient to see meaningful outcomes in these patients,” Dr. Bennani said in an interview.

“An overall response rate of 33% is significant, because most other agents that were FDA approved in this patient population have response rates around 30%,” she said, adding that it’s possible that the patients with rapid progression had disease too advanced to be effectively treated with a checkpoint inhibitor.

“Ideally however, if we want to move forward, it will need to be with combinations of checkpoint inhibitors with HDAC [histone deacetylase] inhibitors, hypomethylating agents, or even PI3 kinase inhibitors,” she said.

­The study was supported by Bristol-Myers Squibb. Dr. Bennani reported research funding and advisory board activities for Bristol-Myers Squibb and others.

LUGANO, SWITZERLAND – A combination of 5-azacytidine and romidepsin showed promising activity in patients with peripheral T cell lymphomas, particularly angioimmunoblastic T-cell lymphoma (AITL) and primary cutaneous follicular helper T-cell lymphoma (PTCL-TFH), results of a phase 2 study showed.

Of 16 patients with AITL or PTCL-TFH, 11 (69%) had a clinical response to the 5-azacytidine (AZA)/romidepsin combination, including 8 (50%) with complete responses (CRs), and 3 with partial responses (PRs), reported Lorenzo Falchi, MD, of Columbia University Medical Center and New York Presbyterian Hospital, New York, and colleagues.

“We show that the combination of oral AZA/romidepsin is remarkably active in patients with T-cell lymphomas. Clearly more patients with other subtypes are needed to better evaluate this combination,” Dr. Falchi said at the International Conference on Malignant Lymphoma.

The combination is intended to target epigenetic changes in PTCLs, which often bear mutations in TET2, DNMT3A, and IDH2. These mutations create global hypermethylation and cause transcriptional silencing of tumor suppressor genes, Dr. Falchi said.

Both histone deacetylase inhibitors such as romidepsin, and hypomethylating agents such as AZA have been shown to have single-agent activity against PTCL, and as previously reported at the 2018 T-cell Lymphoma Forum, the combination produced a higher overall response rate (ORR) and prolonged progression-free survival (PFS) in patients with T-cell lymphomas.

Dr. Falchi presented the phase 2 results at 15-ICML. A total of 25 patients with newly diagnosed or relapsed/refractory PTCL were treated with AZA 300 mg daily on days 1-14 and romidepsin 14 mg/m² on days 8, 15, and 22, every 35 days.

A total of 24 patients were evaluable for response. The ORR – the primary endpoint – was achieved in 14 patients (58%), and included 10 CRs and 4 PRs. Three additional patients had stable disease, and six patients experienced disease progression (response data for one patient was not complete at the time of the presentation).

In total, 11 of 16 patients with AITL/PTCL-TFH had responses, compared with 3 of 8 patients with other histologies.

A secondary analysis of 16 patients with information on mutational status showed that 10 of 12 patients with TET2 mutations (83%) had responses, including 8 CRs and 2 PRs. Two additional patients with TET2 mutations had disease progression. In contrast, among four patients without TET2 mutations, one had a CR, one a PR, and two had disease progression.

Of the 10 patients overall with CRs, 5 patients were receiving the combination in the first line, and 5 patients were receiving it for relapsed/refractory disease.

Median PFS among all patients was 8.7 months. The median overall survival has not been reached. Among patients with the AITL or PTCL-TFH subtypes, median PFS was 8.7 months, compared with 2.3 months for patients with other histologies.

The most frequent hematologic grade 3 or 4 adverse events were thrombocytopenia and neutropenia. The most frequent nonhematologic grade 3 or 4 events included lung infection and febrile neutropenia. Common grade 1 or 2 toxicities included anemia, diarrhea, fatigue, nausea, and vomiting. No patients discontinued therapy because of adverse events.

Dr. Falchi noted that a phase 1 trial evaluating the immune checkpoint inhibitor durvalumab (Imfinzi) with AZA or romidepsin alone or in combination, or pralatrexate and romidepsin, is currently recruiting.

Dr. Falchi reported having no financial disclosures. Other investigators reported funding from Celgene, which supported the study.

Two additional patients with TET2 mutations had disease progression. In contrast, among four patients without TET2 mutations, one had a CR, one a PR, and two had disease progression.

Of the 10 patients overall with CRs, 5 patients were receiving the combination in the first line, and 5 patients were receiving it for relapsed/refractory disease.

Median PFS among all patients was 8.7 months. The median overall survival has not been reached. Among patients with the AITL or PTCL-TFH subtypes, median PFS was 8.7 months, compared with 2.3 months for patients with other histologies.

The most frequent hematologic grade 3 or 4 adverse events were thrombocytopenia and neutropenia. The most frequent nonhematologic grade 3 or 4 events included lung infection and febrile neutropenia. Common grade 1 or 2 toxicities included anemia, diarrhea, fatigue, nausea, and vomiting. No patients discontinued therapy because of adverse events.

Dr. Falchi noted that a phase 1 trial evaluating the immune checkpoint inhibitor durvalumab (Imfinzi) with AZA or romidepsin alone or in combination, or pralatrexate and romidepsin, is currently recruiting.

Dr. Falchi reported having no financial disclosures. Other investigators reported funding from Celgene, which supported the study.

The Food and Drug Administration requested on July 24 that Allergan pull six brands of textured breast implants and breast expanders from the U.S. market, an action the agency took because of new data that substantially increased the number of women who developed a rare cancer – anaplastic large-cell lymphoma – in association with receiving these textured breast devices.

This is the first product recall the FDA has made to address the issue of breast implant–associated anaplastic large-cell lymphoma (BIA-ALCL), a complication that first came to national attention with a 2011 FDA report that had tallied 60 identified BIA-ALCL cases worldwide. By the end of September 2018, the number of reported worldwide BIA-ALCL cases had jumped to 457 cases reported to the agency via medical device reporting. In July 2019, the FDA cited a total of 573 unique, global case reports for BIA-ALCL sent to the agency through July 6, including 33 episodes that led to death.

It was inclusion of these additional 116 cases since September 2018 and 24 additional deaths that led FDA researchers to conclude that “the risk of BIA-ALCL with Allergan BIOCELL textured implants is approximately six-times the risk of BIA-ALCL with textured implants from other manufacturers marketing in the U.S.,” according to a statement from the agency.

The FDA is not recommending that patients who received one of the six products covered by the recall have the material removed if symptoms have not appeared because of the potential risk from explantation.

The agency also stressed that its investigation of the risk posed by placement of other brands of textured breast implants is ongoing and that overall less than 5% of all breast implants performed in current U.S. practice involve the macrotextured implants of the type specified in the Allergan recall.

This U.S. recall follows similar actions taken in France (and the rest of the European Union), Canada, and Australia, and it contrasts with the agency’s prior decision in May 2019 not to start a recall or ban of textured implants following a advisory committee meeting that discussed BIA-ALCL.

The six products that Allergan agreed to recall from marketing at the FDA’s request are four textured breast implants (Natrelle Saline-Filled Breast Implants, Natrelle Silicone-Filled Breast Implants, Natrelle Inspira Silicone-Filled breast Implants, and Natrelle 410 Highly Cohesive Anatomically Shaped Silicone-Filled Breast Implants) and two tissue expanders used prior to a breast implant (Natrelle 133 Plus Tissue Expander and the Natrelle 133 Tissue Expander with Suture Tabs).

FDA officials said they are considering recommendations for changes to the labeling of breast implant products, including a possible boxed warning and beefed up patient information.

“The recall of these textured implants is a big deal in protecting women from the potential risks of developing, and dying from, this rare type of aggressive lymphoma,” Joshua Brody, MD, a medical oncologist and director of the lymphoma immunotherapy program at Mount Sinai Medical Center in New York said in a statement. “While case reports have suggested a potential link between some types of breast implants and this disease – anaplastic lymphoma – for over 20 years, it has taken time to gain sufficient evidence to suggest, and understand, the causality. Some types of implants induce inflammation, which can both increase the chance of developing cancer, and also help to ‘hide’ developing cancers from the immune system. By preventing further use of these implants, the FDA is helping women to protect themselves from the medically serious and emotionally exhausting effects of these risks.”

Dr. Brody reported having no relevant disclosures.

NEWPORT BEACH, CALIF. – Preclinical research has revealed workarounds that may make chimeric antigen receptor (CAR) T-cell therapy feasible for patients with T-cell malignancies.

Researchers have found that using allogeneic cells for CAR T-cell therapy can eliminate contamination by malignant T cells, and editing those allogeneic T cells to delete the target antigen and the T-cell receptor alpha chain (TRAC) can prevent fratricide and graft-versus-host disease (GVHD).

Additionally, an interleukin-7 molecule called NT-I7 has been shown to enhance CAR T-cell proliferation, differentiation, and tumor killing in a mouse model of a T-cell malignancy.

John F. DiPersio, MD, PhD, of Washington University in St. Louis, described this work in a presentation at the Acute Leukemia Forum of Hemedicus.
 

Obstacles to development

“The primary obstacle for targeting T-cell malignancies with a T cell is that all of the targets that are on the [malignant] T cells are also expressed on the normal T cells,” Dr. DiPersio said. “So when you put a CAR into a normal T cell, it just kills itself. It’s called fratricide.”

A second issue that has limited development is that the phenotype of the malignant T cell in the blood is similar to a normal T cell, so they can’t be separated, he explained.

“So if you were to do anything to a normal T cell, you would also be doing it, in theory, to the malignant T cell – in theory, making it resistant to therapy,” he said.

A third obstacle, which has been seen in patients with B-cell malignancies as well, is the inability to harvest enough T cells to generate effective CAR T-cell therapy.

And a fourth obstacle is that T cells from patients with malignancies may not function normally because they have been exposed to prior therapies.

Dr. DiPersio and his colleagues believe these obstacles can be overcome by creating CAR T-cell therapies using T cells derived from healthy donors or cord blood, using gene editing to remove the target antigen and TRAC, and using NT-I7 to enhance the efficacy of these universal, “off-the-shelf” CAR T cells.

The researchers have tested these theories, and achieved successes, in preclinical models. The team is now planning a clinical trial in patients at Washington University. Dr. DiPersio and his colleagues also created a company called WUGEN that will develop the universal CAR T-cell therapies if the initial proof-of-principle trial proves successful.
 

UCART7

One of the universal CAR T-cell therapies Dr. DiPersio and his colleagues have tested is UCART7, which targets CD7. Dr. DiPersio noted that CD7 is expressed on 98% of T-cell acute lymphoblastic leukemias (T-ALLs), 24% of acute myeloid leukemias, natural killer (NK) cells, and T cells.

The researchers created UCART7 by using CRISPR/Cas9 to delete CD7 and TRAC from allogeneic T cells and following this with lentiviral transduction with a third-generation CD7-CAR. The team found a way to delete both TRAC and CD7 in a single day with 95% efficiency, Dr. DiPersio noted.

“Knocking out CD7 doesn’t seem to have any impact on the expansion or trafficking of these T cells in vivo,” Dr. DiPersio said. “So we think that deleting that target in a normal T cell will not affect its overall ability to kill a target when we put a CAR into those T cells.”

In fact, the researchers’ experiments showed that UCART7 can kill T-ALL cells in vitro and target primary T-ALL in vivo without inducing GVHD (Leukemia. 2018 Sep;32[9]:1970-83.)
 

UCART2 and NT-I7

Dr. DiPersio and his colleagues have also tested UCART2, an allogeneic CAR T-cell therapy in which CD2 and TRAC are deleted. The therapy targets CD2 because this antigen is expressed on T-ALL and other T-cell and NK-cell malignancies. Experiments showed that UCART2 targets T-cell malignancies, including T-ALL and cutaneous T-cell lymphoma, in vitro.

The researchers also tested UCART2 in a mouse model of Sézary syndrome. In these experiments, UCART2 was combined with NT-I7.

NT-I7 enhanced the proliferation, persistence, and tumor killing ability of UCART2. Sézary mice that received UCART2 and NT-I7 had “virtually no tumor burden,” according to researchers, and survived longer than mice treated with UCART2 alone (Blood. 2018;132:340).

Dr. DiPersio noted that there was no cytokine release syndrome because these were immunodeficient mice. However, cytokine release syndrome may be a side effect of NT-I7 in patients as NT-I7 induces rapid expansion of CAR T cells.

Dr. DiPersio reported ownership and investment in WUGEN and Magenta Therapeutics. He also has relationships with Cellworks Group, Tioma Therapeutics, RiverVest Venture Partners, Bioline, Asterias Biotherapeutics, Amphivena Therapeutics, Bluebird Bio, Celgene, Incyte, NeoImuneTech, and MacroGenics.
