Positive Results for Tecvayli/Darzalex Faspro Combo
Johnson & Johnson says initial results from the Phase 3 MajesTEC-3 study of the combination of Tecvayli (teclistamab-cqyv) and Darzalex Faspro (daratumumab and hyaluronidase-fihj) showed the combination significantly improved progression-free survival and overall survival versus standard of care in relapsed/refractory multiple myeloma. A company statement says the independent data monitoring committee has recommended unblinding the study based on the statistically significant results.
Tecvayli is described as a first-in-class bispecific T-cell engager antibody therapy that uses innovative science to activate the immune system by binding to the CD3 receptor expressed on the surface of T-cells and to the B-cell maturation antigen expressed on the surface of multiple myeloma cells and some healthy B-lineage cells. It was approved by FDA in 10/2022 as an off-the-shelf antibody that is administered as a subcutaneous treatment for adults with relapsed or refractory multiple myeloma who have received at least four prior lines of therapy.
Darzalex Faspro was approved in 5/2020 and is now approved for 10 indications in multiple myeloma, four of which are for frontline treatment in newly diagnosed patients who are transplant eligible or ineligible. Darzalex itself was approved in 11/2015 as the first CD38-directed antibody approved to treat multiple myeloma.
