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).
