The Food and Drug Administration has granted accelerated approval for glofitamab (Columvi) for use in certain types of lymphoma.

The indication is for use in adult patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL) not otherwise specified or with LBCL arising from follicular lymphoma who have received two or more lines of systemic therapy.

The product is a T cell–engaging bispecific antibody developed by Genentech, which has a similar product, mosunetuzumab-axgb (Lunsumio), for the treatment of follicular lymphoma. Lunsumio was approved in December 2022.

These drugs could be considered a first choice in the setting of third-line therapy, suggests an expert writing recently in The New England Journal of Medicine.

Nancy Bartlett, MD, from the Siteman Cancer Center, Washington University in St. Louis, is the author of an editorial that accompanied the publication of results with glofitamab in the pivotal trial that led to its approval.

“Bispecific agents will be an excellent option for the 60% of patients in whom second-line CAR [chimeric antigen receptor] T-cell therapy fails,” she wrote in her editorial.

Dr. Bartlett suggests that these agents may be preferred over CAR T cells. “If longer follow-up confirms that the majority of complete remissions with bispecific agents are durable, on the basis of the advantages of availability (including in the community setting) and more favorable immediate and late toxic-effect profiles, bispecific agents could be considered as the initial choice. ... CAR T-cell therapy could be held in reserve for patients who do not have a complete response or who have a relapse after a complete response.”
 

Most common form of non-Hodgkin’s lymphoma

DLBCL is the most common form of non-Hodgkin’s lymphoma in the United States, the company noted in a press release. While many people with DLBCL are responsive to treatment, the majority of those who experience relapse or whose condition is refractory to subsequent treatments have poor outcomes.

“Patients with relapsed or refractory diffuse large B-cell lymphoma may experience rapid progression of their cancer and often urgently need an effective treatment option that can be administered without delay,” commented Krish Patel, MD, director of the lymphoma program at the Swedish Cancer Institute in Seattle, who is an investigator on the clinical trial that led to the product’s approval. He said that the results from trials suggest that glofitamab gives patients “a chance for complete remission with a fixed-duration immunotherapy and that such remissions can potentially be sustained after the end of their treatment.”

The accelerated approval is based on response rate and durability of response results from the phase 1/2 NP30179 study.

Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

This trial involved 132 patients with DLBCL who experienced relapse or whose condition was refractory to prior therapies. About one-third of patients (30%) had received prior CAR T-cell therapy. Additionally, for 83% of patients, the condition was refractory to their most recent therapy.

Glofitamab was given to all patients as a fixed course for 8.5 months.

More than half (56%) achieved an overall response, and 43% achieved a complete response. Over two-thirds (68.5%) of those who responded continued to respond for at least 9 months The median duration of response was 1.5 years.

The most common adverse events were cytokine release syndrome (CRS; 70%), which may be serious or life-threatening; musculoskeletal pain (21%); fatigue (20%); and rash (20%). CRS was generally of low grade (52% of patients experienced grade 1 CRS, and 14% experienced grade 2).

Results from the NP30179 trial were published in December 2022.

The complete response rates seen with glofitamab rivals the durable complete response that has been observed with CAR T-cell therapy, Dr. Bartlett noted in the accompanying editorial. “Although these results are promising, it is still too early to estimate the curative potential of glofitamab.”

New data released by the U.S. Department of Defense show that the incidence of many types of cancer is higher among military pilots and aviation support personnel in comparison with the general population.

“Military aircrew and ground crew were overall more likely to be diagnosed with cancer, but less likely to die from cancer compared to the U.S. population,” the report concludes.

The study involved 156,050 aircrew and 737,891 ground crew. Participants were followed between 1992 and 2017. Both groups were predominantly male and non-Hispanic.

Data on cancer incidence and mortality for these two groups were compared with data from groups of similar age in the general population through use of the Surveillance, Epidemiology, and End Results (SEER) Database of the National Cancer Institute.

For aircrew, the study found an 87% higher rate of melanoma, a 39% higher rate of thyroid cancer, a 16% higher rate of prostate cancer, and a 24% higher rate of cancer for all sites combined.

A higher rate of melanoma and prostate cancer among aircrew has been reported previously, but the increased rate of thyroid cancer is a new finding, the authors note.

The uptick in melanoma has also been reported in studies of civilian pilots and cabin crew. It has been attributed to exposure to hazardous ultraviolet and cosmic radiation.

For ground crew members, the analysis found a 19% higher rate of cancers of the brain and nervous system, a 15% higher rate of thyroid cancer, a 9% higher rate of melanoma and of kidney and renal pelvis cancers, and a 3% higher rate of cancer for all sites combined.

There is little to compare these findings with: This is the first time that cancer risk has been evaluated in such a large population of military ground crew.
 

Lower rates of cancer mortality

In contrast to the increase in cancer incidence, the report found a decrease in cancer mortality.

When compared with a demographically similar U.S. population, the mortality rate among aircrew was 56% lower for all cancer sites; for ground crew, the mortality rate was 35% lower.

However, the report authors emphasize that “it is important to note that the military study population was relatively young.”

The median age at the end of follow-up for the cancer incidence analysis was 41 years for aircrew and 26 years for ground crew. The median age at the end of follow-up for the cancer mortality analysis was 48 years for aircrew and 41 years for ground crew.

“Results may have differed if additional older former Service members had been included in the study, since cancer risk and mortality rates increase with age,” the authors comment.

Other studies have found an increase in deaths from melanoma as well as an increase in the incidence of melanoma. A meta-analysis published in 2019 in the British Journal of Dermatology found that airline pilots and cabin crew have about twice the risk of melanoma and other skin cancers than the general population. Pilots are also more likely to die from melanoma.
 

Further study underway

The findings on military air and ground crew come from phase 1 of a study that was required by Congress in the 2021 defense bill. Because the investigators found an increase in the incidence of cancer, phase 2 of the study is now necessary.

The report authors explain that phase 2 will consist of identifying the carcinogenic toxicants or hazardous materials associated with military flight operations; identifying operating environments that could be associated with increased amounts of ionizing and nonionizing radiation; identifying specific duties, dates of service, and types of aircraft flown that could have increased the risk for cancer; identifying duty locations associated with a higher incidence of cancers; identifying potential exposures through military service that are not related to aviation; and determining the appropriate age to begin screening military aircrew and ground crew for cancers.

The European Commission has granted conditional marketing authorization for etranacogene dezaparvovec (Hemgenix), the first and only one-time gene therapy for the treatment of severe and moderately severe hemophilia B (congenital factor IX deficiency) in adults without a history of factor IX inhibitors.

The approval means that the product will now be available in all the countries of the European Union as well as the European Economic Area.

The gene therapy was approved in the United States in November 2022. It was launched with a price tag of $3.5 million, making it the most expensive treatment to date.

The treatment comprises a one-time infusion of a functional gene that acts as a blueprint for coagulation factor IX, a protein important for blood clotting, stated the manufacturer, CSL.

People living with hemophilia B currently require lifelong treatment of intravenous infusions of factor IX to maintain sufficient levels, which can have a significant impact on their quality of life and well-being, the company explained in its press release.

The approval was based on findings from the pivotal HOPE-B trial, a single-arm, open-label study of 54 men who relied on factor IX replacement therapy; first results from this trial were reported at the 2020 annual meeting of the American Society of Hematology.

The results showed that patients with hemophilia B treated with the gene therapy demonstrated stable and durable increases in mean factor IX activity (with a mean factor IX activity of 36.9%), which led to an adjusted annualized bleeding rate reduction of 64%.

After receiving the gene therapy, 96% of patients discontinued routine factor IX prophylaxis and mean factor IX consumption was reduced by 97% at 18 months post treatment compared with the lead-in period, the company noted.

“Data from the HOPE-B study demonstrate the potential of Hemgenix to remove the need for routine prophylaxis by providing durable factor IX activity, as well as improved bleeding outcomes and quality of life for people with hemophilia B,” said one of the trialists, Wolfgang Miesbach, MD, PHD, head of coagulation disorders at the Comprehensive Care Center, University Hospital of Frankfurt, Germany.

This European approval “marks an important step forward in the treatment of hemophilia B, which could be transformative for people who are debilitated by bleeds into their muscles, joints, and internal organs, alleviating the burden of lifelong intravenous infusions of factor IX products,” Dr. Miesbach said in the company press release.

The Food and Drug Administration has approved efanesoctocog alfa (Altuviiio), a first-in-class, high-sustained factor VIII replacement therapy for adults and children with hemophilia A.

The product is used once a week and is indicated for routine prophylaxis and on-demand treatment to control bleeding episodes, as well as to control bleeding during surgery (perioperative management).

The manufacturer, Sanofi, says that this is “the first and only hemophilia A treatment that delivers normal to near-normal factor activity levels (over 40%) for most of the week with once-weekly dosing, and significantly reduces bleeds compared to prior factor VIII prophylaxis.”

With this product, “we have the opportunity to provide near-normal factor activity levels for an extended period of time (the majority of a week) with a single dose, which is a first for hemophilia A,” said Angela Weyand, MD, of Michigan Medicine, who was involved in the pivotal phase 3 XTEND-1 trial that led to approval.

Results from the XTEND-1 trial were recently published online in The New England Journal of Medicine. The results show that one injection of efanesoctocog alfa, a factor VIII therapy, resolved almost all bleeding episodes (97%) in the overall patient population and weekly prophylaxis provided mean factor VIII activity in the normal or near-normal range (> 40 IU/dL) for most of the week, as previously reported by this news organization.

The researchers noted that the factor VIII therapies that have been available up to now need to be administered frequently.

In an accompanying editorial, Cindy Leissinger, MD, called efanesoctocog alfa a “victory” for patients with hemophilia A.

“In a crowded field of transformative therapies for hemophilia, efanesoctocog alfa stands out as a winner – a major therapeutic advance that achieves highly protective factor VIII levels with a once-weekly infusion,” wrote Dr. Leissinger, director of the Louisiana Center for Bleeding and Clotting Disorders at Tulane University in New Orleans.

Sanofi said that Altuviiio is expected to be commercially available in April 2023. The company said that it will price the product at parity to the annual cost of treating a prophylaxis patient with its Eloctate product (antihemophilic factor [recombinant], Fc fusion protein). Sanofi will provide comprehensive patient support services and resources online and at 1-855-MyALTUVIIIO (855-692-5888).

The Food and Drug Administration has approved efanesoctocog alfa (Altuviiio), a first-in-class, high-sustained factor VIII replacement therapy for adults and children with hemophilia A.

The product is used once a week and is indicated for routine prophylaxis and on-demand treatment to control bleeding episodes, as well as to control bleeding during surgery (perioperative management).

The manufacturer, Sanofi, says that this is “the first and only hemophilia A treatment that delivers normal to near-normal factor activity levels (over 40%) for most of the week with once-weekly dosing, and significantly reduces bleeds compared to prior factor VIII prophylaxis.”

With this product, “we have the opportunity to provide near-normal factor activity levels for an extended period of time (the majority of a week) with a single dose, which is a first for hemophilia A,” said Angela Weyand, MD, of Michigan Medicine, who was involved in the pivotal phase 3 XTEND-1 trial that led to approval.

Results from the XTEND-1 trial were recently published online in The New England Journal of Medicine. The results show that one injection of efanesoctocog alfa, a factor VIII therapy, resolved almost all bleeding episodes (97%) in the overall patient population and weekly prophylaxis provided mean factor VIII activity in the normal or near-normal range (> 40 IU/dL) for most of the week, as previously reported by this news organization.

The researchers noted that the factor VIII therapies that have been available up to now need to be administered frequently.

In an accompanying editorial, Cindy Leissinger, MD, called efanesoctocog alfa a “victory” for patients with hemophilia A.

“In a crowded field of transformative therapies for hemophilia, efanesoctocog alfa stands out as a winner – a major therapeutic advance that achieves highly protective factor VIII levels with a once-weekly infusion,” wrote Dr. Leissinger, director of the Louisiana Center for Bleeding and Clotting Disorders at Tulane University in New Orleans.

Sanofi said that Altuviiio is expected to be commercially available in April 2023. The company said that it will price the product at parity to the annual cost of treating a prophylaxis patient with its Eloctate product (antihemophilic factor [recombinant], Fc fusion protein). Sanofi will provide comprehensive patient support services and resources online and at 1-855-MyALTUVIIIO (855-692-5888).

The U.S. Food and Drug Administration has approved mosunetuzumab-axgb (Lunsumio) for use in patients with relapsed or refractory follicular lymphoma who have received at least two previous systemic therapies.

This product is a first-in-class bispecific antibody that is designed to target CD20 on the surface of B cells and CD3 on the surface of T cells. This dual targeting activates and redirects a patient’s existing T cells to engage and eliminate target B cells by releasing cytotoxic proteins into the B cells, according to the manufacturer, Genentech.

Mosunetuzumab-axgb is administered as an intravenous infusion for a fixed duration, which allows for time off therapy, and can be infused in an outpatient setting, the company noted.

The drug was granted an accelerated approval on the basis of response rate data from the phase 2 GO29781 trial. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial, the company noted.

The GO29781 study was carried out in individuals with pretreated follicular lymphoma, including those who were at high risk for disease progression or whose disease was refractory to prior therapies.

A complete response was achieved in 60% of patients (54 of 90).

An objective response rate (a combination of complete and partial responses) was seen in 80% of patients who received the drug, with a majority maintaining responses for at least 18 months.

The median duration of response among those who responded was 22.8 months.

Safety data come from 218 patients with hematologic cancers who received mosunetuzumab-axgb at the recommended dose. The most common adverse event was cytokine release syndrome (39%), which can be severe and life-threatening. The median duration of cytokine release syndrome events was 3 days (range, 1-29 days). Other common adverse events (≥ 20%) included fatigue, rash, pyrexia, and headache.

“This approval is a significant milestone for people with relapsed or refractory follicular lymphoma, who have had limited treatment options until now,” said Elizabeth Budde, MD, PhD, from the City of Hope, Los Angeles, division of lymphoma, and clinical trial investigator.

Dr. Budde presented data on mosunetuzumab-axgb at the 2021 annual meeting of the American Society of Hematology, as reported by this news organization.

She noted that the 60% complete response rate seen with this new drug contrasts with the 14% that has been seen for historical controls.

“We have seen deep and durable responses in heavily pretreated, high-risk relapsed/refractory follicular lymphoma patients with fixed-duration treatment. We also observed a very favorable tolerability profile, with most cytokine release syndrome confined to cycle 1 and low grade, and treatment administration is without mandatory hospitalization,” she commented at the time.

A lymphoma specialist who was not involved in the study told this news organization at the time that he was favorably impressed by the findings.

“To me, the single-agent data looks really outstanding, with a response rate of 80%, a complete response rate of 60%, and a median duration of response of 23 months, and really very acceptable rates of cytokine release syndrome,” commented Brad S. Kahl, MD, from the Siteman Cancer Center and Washington University in St. Louis.

“I think as a single agent – if it does get approval – it will be a really valuable addition to the armamentarium in follicular lymphoma,” he added.

The U.S. Food and Drug Administration has approved olutasidenib (Rezlidhia) for use in certain patients with relapsed or refractory (R/R) acute myeloid leukemia (AML).

Specifically, the drug is approved for use in patients who have R/R AML with a susceptible isocitrate dehydrogenase 1 (IDH1) mutation as detected by an FDA-approved test.

The FDA also approved the Abbott RealTime IDH1 Assay to select patients for treatment.

Olutasidenib is an oral inhibitor of mutated IDH1 that has been designed to bind and inhibit mutated IDH1 to reduce hydroxyglutarate levels and restore cellular differentiation of myeloid cells, says the manufacturer, Rigel.

About half of all patients with AML have relapse after treatment and remission, and about 10%-40% have refractory cases and do not achieve remission even after intensive treatment, the company noted.

“Given the limited treatment options for adult patients with mIDH1 R/R AML, who typically have a poor prognosis, olutasidenib may provide an effective new treatment option with a well-characterized safety profile,” Jorges Cortes, MD, director of the Georgia Cancer Center, Augusta, commented in the company press release. He was an investigator on the phase 2 trial that led to the drug’s approval.

This was Study 2102-HEM-101 (NCT02719574), an open-label, single-arm, multicenter clinical trial that included 147 adult patients with relapsed or refractory AML with an IDH1 mutation confirmed using the Abbott assay.

Olutasidenib was given orally at 150 mg twice daily until disease progression, unacceptable toxicity, or hematopoietic stem cell transplantation (performed in 16 patients [11%]). The median treatment duration was 4.7 months (range, 0.1-26 months).

The FDA noted that efficacy was established on the rate of complete remission (CR) plus complete remission with partial hematologic recovery (CRh), the duration of CR+CRh, and the rate of conversion from transfusion dependence to independence.

The CR+CRh rate was 35% (95% confidence interval, 27%-43%), including 32% CR and 2.7% CRh. The median time to CR+CRh was 1.9 months (range, 0.9-5.6 months), and the median duration of CR+CRh was 25.9 months (95% CI, 13.5 months to not reached).

Commenting on these results in the company statement, Dr. Cortes noted that among the patients who responded, more than 90% were experiencing incomplete remission. He added that the “25.9 months median duration of CR+CRh is a clinically meaningful improvement for AML patients and appears to be longer than currently available treatment options.”

The FDA also noted that among the 86 patients who were dependent on red blood cell (RBC) and/or platelet transfusions at baseline, 29 (34%) became independent of RBC and platelet transfusions during any 56-day postbaseline period.

Of the 61 patients who were independent of both RBC and platelet transfusions at baseline, 39 (64%) remained transfusion-independent during any 56-day post-baseline period.

The most common adverse reactions (≥ 20%) were nausea, fatigue/malaise, arthralgia, constipation, leukocytosis, dyspnea, fever, rash, mucositis, diarrhea, and transaminitis.

The prescribing information contains a boxed warning about the risk for differentiation syndrome, which can be fatal.

Differentiation syndrome is associated with rapid proliferation and differentiation of myeloid cells and may be life-threatening or fatal, the company explained. Symptoms may include leukocytosis, dyspnea, pulmonary infiltrates/pleuropericardial effusion, kidney injury, hypotension, fever, and weight gain.

In the trial, differentiation syndrome was observed in 16% of patients, with grade 3 or 4 occurring in 8% of patients treated and death in 1% of patients. It occurred as early as 1 day and up to 18 months after starting treatment.

In most cases, differentiation syndrome was manageable with dose interruption and corticosteroids, the company said. Of the 25 patients who experienced differentiation syndrome, 19 (76%) recovered after treatment or after dose interruption.

Further details are available in the full prescribing information.

The Food and Drug Administration has announced it will not approve the investigational drug poziotinib (Spectrum Pharmaceuticals) for the treatment of certain patients with non–small cell lung cancer (NSCLC).

The clinical data the company submitted were deemed insufficient for approval, and additional data including a randomized clinical trial would be needed, the agency said.

The move is not a surprise, as the FDA’s Oncologic Drugs Advisory Committee (ODAC) voted 9-4 against approval when it met to discuss the drug in September, as reported at the time by this news organization.

Poziotinib was developed for patients with previously treated locally advanced or metastatic NSCLC harboring HER2 exon 20 insertion mutations, which occur in about 2% of patients with NSCLC.

Poziotinib is a potent oral pan-HER tyrosine kinase inhibitor with activity in patients with these mutations. Clinical data from the ZENITH20 Trial reported last year showed an overall response rate of 43.8%, and the drug was described as showing “clinically meaningful efficacy for treatment-naive NSCLC HER2 exon 20 mutations with [daily] dosing.”

“We continue to believe that poziotinib could present a meaningful treatment option for patients with this rare form of lung cancer, for whom other therapies have failed,” commented Tom Riga, president and chief executive officer of Spectrum Pharmaceuticals. 

However, following multiple interactions with the FDA, “we have made the strategic decision to immediately deprioritize the poziotinib program,” he said. The change is effective immediately, and the company is now in the process of reducing its R&D workforce by approximately 75%.
 

Drug development criticized

At the ODAC meeting, several panelists were openly critical of the approach Spectrum took in developing the drug. The FDA’s top cancer official, Richard Pazdur, MD, characterized Spectrum’s work as “poor drug development” and likened it to “building a house on quicksand.”

The FDA panel detailed several ways they felt that the poziotinib application fell short of the benchmarks needed for accelerated approval.

To win such a speedy clearance, a company needs to show that a drug provides a meaningful therapeutic benefit over existing treatments. The panel argued that, so far, poziotinib appears to be inferior to a product already available for HER2-mutant NSCLC, trastuzumab deruxtecan (Enhertu), which received accelerated approval in August.

The FDA staff contrasted a reported overall response rate for poziotinib, which was estimated at 28% (from data discussed at the meeting), with the overall response rate for trastuzumab deruxtecan, which is 58%.

Harpreet Singh, MD, a director in the FDA’s oncology division, asked the panel to consider what they would do as a physician treating a patient with this mutation, given the choices that are now available.

“That’s something we’re asking the committee to consider … to think about the context of what’s available to you in the clinic,” Dr. Singh said.

Dr. Singh said she expected that patients and physicians would prefer a drug such as trastuzumab deruxtecan, which has a more established record, regardless of the fact that treatment with poziotinib is more convenient because it is given as a tablet.

Dr. Singh and other staff also raised concerns about side effects of poziotinib, including diarrhea, as well as difficulty determining the right dose.

Katherine Scilla, MD, one of the nine ODAC panelists to vote “no,” echoed these views. Although Dr. Scilla, an oncologist at the University of Maryland, Baltimore, sympathized with the need for options for people with this rare form of lung cancer, she was not persuaded by the data on poziotinib that were presented to support accelerated approval.

“I’m not sure that this represents a meaningful therapeutic benefit over other agents,” she said at the time.

However, following multiple interactions with the FDA, “we have made the strategic decision to immediately deprioritize the poziotinib program,” he said. The change is effective immediately, and the company is now in the process of reducing its R&D workforce by approximately 75%.
 

Drug development criticized

At the ODAC meeting, several panelists were openly critical of the approach Spectrum took in developing the drug. The FDA’s top cancer official, Richard Pazdur, MD, characterized Spectrum’s work as “poor drug development” and likened it to “building a house on quicksand.”

The FDA panel detailed several ways they felt that the poziotinib application fell short of the benchmarks needed for accelerated approval.

To win such a speedy clearance, a company needs to show that a drug provides a meaningful therapeutic benefit over existing treatments. The panel argued that, so far, poziotinib appears to be inferior to a product already available for HER2-mutant NSCLC, trastuzumab deruxtecan (Enhertu), which received accelerated approval in August.

The FDA staff contrasted a reported overall response rate for poziotinib, which was estimated at 28% (from data discussed at the meeting), with the overall response rate for trastuzumab deruxtecan, which is 58%.

Harpreet Singh, MD, a director in the FDA’s oncology division, asked the panel to consider what they would do as a physician treating a patient with this mutation, given the choices that are now available.

“That’s something we’re asking the committee to consider … to think about the context of what’s available to you in the clinic,” Dr. Singh said.

Dr. Singh said she expected that patients and physicians would prefer a drug such as trastuzumab deruxtecan, which has a more established record, regardless of the fact that treatment with poziotinib is more convenient because it is given as a tablet.

Dr. Singh and other staff also raised concerns about side effects of poziotinib, including diarrhea, as well as difficulty determining the right dose.

Katherine Scilla, MD, one of the nine ODAC panelists to vote “no,” echoed these views. Although Dr. Scilla, an oncologist at the University of Maryland, Baltimore, sympathized with the need for options for people with this rare form of lung cancer, she was not persuaded by the data on poziotinib that were presented to support accelerated approval.

“I’m not sure that this represents a meaningful therapeutic benefit over other agents,” she said at the time.

Atezolizumab (Tecentriq) is no longer approved in the United States for use in certain patients with bladder or urinary tract cancer.

The drug is an anti–PD-L1 inhibitor immunotherapy, and continues to be approved for use in lung and liver cancer and melanoma.

The manufacturer, Genentech, announced that it was voluntarily withdrawing the U.S. indication for atezolizumab that covered its use in adults with locally advanced or metastatic urothelial carcinoma (bladder cancer) who are not eligible for cisplatin-containing chemotherapy and whose tumors express PD-L1 or are not eligible for any platinum-containing chemotherapy regardless of PD-L1 status.

The company said that it made the decision after consultation with the Food and Drug Administration.

“While we are disappointed with this withdrawal, we understand the need to uphold the principles of the FDA’s Accelerated Approval Program, which brings innovative medicines to patients sooner,” said Levi Garraway, MD, PhD, Genentech chief medical officer and head of Global Product Development.

Atezolizumab had been granted an accelerated approval for this indication back in 2016, based on response rate data from the IMvigor210 trial.

The company was obliged to conduct a follow-up trial to show clinical benefit, and launched IMvigor130, which it described as “the designated postmarketing requirement to convert the accelerated approval to regular approval.”

The bladder cancer indication for atezolizumab was discussed (alongside several other indications for different immunotherapy drugs) at a historic 3-day meeting of the FDA’s oncologic Drugs Advisory Committee in April 2021. At the time, ODAC voted 10-1 in favor of maintaining the indication for atezolizumab for the first-line treatment of cisplatin-ineligible patients with advanced/metastatic urothelial carcinoma, pending final overall survival results from the IMvigor130 trial.

Genentech has now said that this trial “did not meet the coprimary endpoint of overall survival for atezolizumab plus chemotherapy compared with chemotherapy alone” when used for the first-line treatment of patients with previously untreated advanced bladder cancer.

These data will be presented at an upcoming medical meeting, the company added.

“There is a considerable unmet need for effective and tolerable treatments for people living with advanced bladder cancer and so we regret that the IMvigor130 trial did not cross the statistical threshold for overall survival,” Dr. Garraway commented.

A drug used in the treatment of relapsed/refractory multiple myeloma (RRMM) is in the process of being pulled off the U.S. market by its manufacturer.

The drug is belantamab mafodotin-blmf (Blenrep), an antibody drug conjugate that targets B-cell maturation antigen (BCMA).

The manufacturer, GSK, announced that it has started the process of withdrawing this drug from the market at the request of the U.S. Food and Drug Administration (FDA).

This request follows disappointing results from a large confirmatory trial, known as DREAMM-3, in which the drug failed to meet the primary endpoint of showing an improvement in progression-free survival (PFS).

The company was obliged to carry out this confirmatory trial after the FDA granted an accelerated approval for the drug in August 2020.

The accelerated approval was based on response data, and it was dependent on later trials’ confirming a clinical benefit. In this case, those trials did not confirm a clinical benefit.

“We respect the Agency’s approach to the accelerated approval regulations and associated process,” commented the GSK Chief Medical Officer Sabine Luik.

The company will continue to “work with the U.S. FDA on a path forward for this important treatment option for patients with multiple myeloma.”

Further clinical trials in the DREAMM program are still underway. Results from the DREAMM-7 and DREAMM-8 trials are expected in early 2023.

The company had high hopes for the drug when it was launched. At that time, belanatamab mafodotin-blmf was the only drug on the market that targeted BCMA, and so it was the first drug in its class.

However, it is no longer unique. In the 2 years that it has been available, several other products that target BCMA have been launched for use in the treatment of multiple myeloma. These include the two chimeric antigen receptor T-cell products, idecabtagene vicleucel (Abecma) and ciltacabtagene autoleucel (Carvykti), as well as the bispecific antibody teclistamab (Tecvayli).
 

For relapsed/refractory disease

Belantamab mafodotin-blmf was approved for use in patients with RRMM who had already undergone treatment with one of the three major classes of drugs, namely, an immunomodulatory agent, a proteasome inhibitor, and a CD-38 monoclonal antibody.

Patients who are currently taking the drug and would like to continue doing so will have the option to enroll in a compassionate use program to retain their access to treatment, the company said.

“GSK continues to believe, based on the totality of data available from the DREAMM (DRiving Excellence in Approaches to Multiple Myeloma) development program, that the benefit-risk profile of belantamab mafodotin remains favorable in this hard-to-treat RRMM patient population. Patients responding to belantamab mafodotin experienced durable clinical benefit, and safety remains consistent with the known safety profile,” the company said.
 

Details of DREAMM-3 results

DREAMM-3 was a phase 3 trial that compared single-agent belantamab mafodotin to pomalidomide (Pomalyst) in combination with low-dose dexamethasone (PomDex) for patients with RRMM.

The results for the primary endpoint of PFS did not reach statistical significance: median PFS was 11.2 vs. 7 months with PomDex (hazard ratio, 1.03; 95% confidence interval, 0.72-1.47).

At the time of the primary analysis, the overall survival (OS) data had only achieved 37.5% overall maturity. The median OS was 21.2 vs. 21.1 months with PomDex (HR, 1.14; 95% CI, 0.77-1.68).

The Food and Drug Administration has approved a new immunotherapy combination for use in the treatment of unresectable hepatocellular carcinoma (HCC), the most common type of liver cancer.

The new combination comprises a single dose of tremelimumab (Imjudo, AstraZeneca) followed by treatment with durvalumab (Imfinzi, AstraZeneca) in what is known as the STRIDE (single-tremelimumab regular-interval durvalumab) regimen.

This marks the first worldwide approval for tremelimumab, which is a CTLA-4 antibody.

[embed:render:related:node:247564]

The other drug in the combination, durvalumab, is an anti-PDL1 antibody and is already approved by the FDA for use in several tumor types, including lung cancer, bladder cancer, and biliary tract cancers.

The STRIDE regimen is composed of a single 300-mg dose of tremelimumab followed by durvalumab 1,500 mg given every 4 weeks.

This regimen was used in the HIMALAYA phase 3 trial, which was published in June 2022 in the New England Journal of Medicine.

Results from this trial showed that 30% of patients treated with that combination were still alive at 3 years, compared with 20% of patients who were treated with the standard regimen, sorafenib.

“In addition to this regimen demonstrating a favorable 3-year survival rate in the HIMALAYA trial, safety data showed no increase in severe liver toxicity or bleeding risk for the combination, important factors for patients with liver cancer who also have advanced liver disease,” commented the principal investigator of this trial, Ghassan Abou-Alfa, MD, MBA, attending physician at Memorial Sloan Kettering Cancer Center, New York.

“Patients with unresectable liver cancer are in need of well-tolerated treatments that can meaningfully extend overall survival,” he commented in a press release from the drug’s manufacturer, AstraZeneca.

When the results from this trial were presented earlier this year at the ASCO Gastrointestinal Cancers meeting, the discussant for that abstract, Anthony B. El-Khoueiry, MD, from the University of Southern California, Norris Comprehensive Cancer Center, Los Angeles, suggested that the STRIDE regimen offers a new first-line treatment option for patients with advanced HCC.

He also made several comments about the design of the HIMALAYA trial, which has a third treatment arm in which patients received durvalumab alone. Dr. El-Khoueiry noted that single-agent durvalumab was noninferior to sorafenib, but he added that no conclusions could be drawn about the STRIDE regimen in comparison with durvalumab as a single agent, because the trial was not powered for that.

The STRIDE regimen showed a lower risk of bleeding in comparison with combinations that include VEGF inhibitors (such as bevacizumab), he said, but he also pointed out that this trial excluded patients with main portal vein thrombosis, who are at high risk of bleeding.

Details of adverse events

In the NEJM article, the trialists report that grade 3/4 treatment-emergent adverse events occurred in 50.5% of patients with STRIDE, 37.1% with durvalumab alone, and 52.4% of patients with sorafenib.

The manufacturer noted that severe and fatal immune-mediated adverse reactions may occur, including immune-mediated pneumonitis, colitis, hepatitis, endocrinopathies, dermatologic reactions, and others.

The company also noted that among the patients with unresectable HCC in the HIMALAYA study who received the STRIDE regimen, the most common adverse reactions (occurring in ≥ 20% of patients) were rash, diarrhea, fatigue, pruritus, musculoskeletal pain, and abdominal pain.

Serious adverse reactions occurred in 41% of patients and included hemorrhage (6%), diarrhea (4%), sepsis (2.1%), pneumonia (2.1%), rash (1.5%), vomiting (1.3%), acute kidney injury (1.3%), and anemia (1.3%).

Fatal adverse reactions occurred in 8% of patients who received the combination, including death (1%), intracranial hemorrhage (0.5%), cardiac arrest (0.5%), pneumonitis (0.5%), hepatic failure (0.5%), and immune-mediated hepatitis (0.5%).

Permanent discontinuation of the treatment regimen because of an adverse reaction occurred in 14% of patients.
