Teclistamab Cuts Myeloma Risk of Progression by 71%: J&J
Johnson & Johnson is reporting positive results from a late-stage clinical trial showing that its bispecific antibody therapy Tecvayli (teclistamab-cqyv) significantly improved survival outcomes compared with standard treatments in patients with relapsed or refractory multiple myeloma, including those who had failed commonly used therapies.
The Phase 3 MajesTEC-9 study found that Tecvayli monotherapy reduced the risk of disease progression or death by 71% and lowered the risk of death by 40% versus standard-of-care regimens in patients who were predominantly refractory to anti-CD38 antibodies and lenalidomide (Bristol Myers Squibb's Revlimid), the company says. The results demonstrate superior progression-free survival and overall survival as early as second-line treatment, positioning the therapy as a potential new standard of care earlier in the disease course, it notes.
The study builds on earlier Phase 3 data from MajesTEC-3, which showed survival benefits for Tecvayli in combination with J&J's Darzalex Faspro (daratumumab and hyaluronidase-fihj) in patients who were naïve or sensitive to anti-CD38 therapy. Together, the two trials address different segments of relapsed disease and reinforce the drug’s role across a broad patient population, the company says.
Tecvayli, a first-in-class bispecific T-cell engager targeting BCMA on myeloma cells and CD3 on T cells, received accelerated approval from FDA in 2022 for heavily pretreated multiple myeloma. Multiple myeloma, a blood cancer marked by frequent relapse, remains difficult to treat once patients stop responding to frontline therapies. While treatment options have expanded in recent years, outcomes for patients who become refractory to anti-CD38 antibodies and lenalidomide remain poor, creating a high unmet medical need.
