HR of 0.17! Tech-Dara: A Potent BCMA/CD38 Dual-Targeting Immunotherapy Combination Leads a New Paradigm in Second-Line MM Treatment—MAJEStec-3 Study Heavily Released
At the Late-Breaking Abstract (LBA) session of the 2025 American Society of Hematology (ASH) Annual Meeting, Dr. María-Victoria Mateos, representing the research team, unveiled the highly anticipated results of the MAJEStec-3 study. This marks the first reported Phase III clinical trial of a BCMA-targeted bispecific antibody. Comparing the combination of Teclistamab and Daratumumab ("Tech-Dara") against standard-of-care regimens (Dara-Pd or Dara-Vd) in patients with relapsed/refractory multiple myeloma (RRMM), the study delivered historic results. The Tech-Dara combination achieved a Hazard Ratio (HR) for progression-free survival of 0.17—the most profound efficacy signal reported to date for BCMA-targeted therapies—signaling a potential "functional cure" for patients with early relapse.
