Multiple Myeloma Treatment from Regeneron Gets FDA Accelerated Approval
Linvoseltamab-gcpt, marketed as Lynozyfic, is a bispecific antibody designed to facilitate T cell activation and cancer cell killing.
Firsts for FDA multiple myeloma approvals
In a press release, Regeneron said the treatment is the first of its kind approved by FDA to treat multiple myeloma: a bispecific antibody engineered to bridge B-cell maturation antigen (BCMA) on multiple myeloma cells with CD3 protein-expressing T cells (1). This design, according to the company, facilitates T cell activation and cancer cell killing.
FDA’s approval, according to the press release, was based on the rate and durability of response observed in a Phase I/II trial (LINKER-MM1), with continued approval contingent upon the verification and description of the treatment’s clinical benefits in a confirmatory trial (1). After an initial step-up dosing regimen followed by a full dose administered weekly, linvoseltamab-gcpt can be dosed every two weeks starting at week 14 and every four weeks if there is a very good partial response, or better, after the completion of 24 weeks of therapy, marking another first in an FDA approval for a multiple myeloma treatment.
“The FDA approval of Lynozyfic reinforces the strength of our bispecific antibody program as well as our commitment to delivering critical medicines to the cancer community,”
Treatment moving forward in Europe
Regeneron has also advanced linvoseltamab under the Lynozyfic brand name in Europe.
In the US, Regeneron said, more than 36,000 diagnoses and 12,000 deaths from multiple myeloma are projected in 2025, among an average of more than 187,000 cases diagnosed annually worldwide (1). Approximately 8000 US patients are living with multiple myeloma that has progressed after three lines of therapy, 4000 of those whose disease has progressed following four or more therapies. Despite advancements in treatment that slow progression of the cancer, it remains incurable at the present time.
