A bispecific plus daratumumab cut the risk of progression by more than 80% versus standard doublets, bringing bispecifics to second line.

PFS median not reached vs 18.1 months; 36-month PFS 83.4% vs 29.7% (HR ~0.17). Approved 5 March 2026 for ≥1 prior line; EU approval followed. Infection prophylaxis mandatory.

Progression-free survival at 36 monthsprimarysurrogate endpoint
  • 83.4 vs 29.7 out of 100 alive without the cancer growing at 36 months with Teclistamab + daratumumab compared with Dara-Pd / Dara-Vd; 53.7 more per 100.
  • Roughly one extra person helped for every 2 treated. That is a rough figure taken from the two percentages, not a guarantee for any one person.
  • Put another way, the treated group had about 83 percent lower chance of the event at any given time (hazard ratio 0.17).
  • This is a surrogate endpoint: it measures the cancer being controlled or absent on scans and tests, which often, but not always, translates into living longer.
  • These results apply to the people the trial enrolled: Relapsed/refractory myeloma after 1-3 prior lines: teclistamab + daratumumab vs Dara-Pd or Dara-Vd. People in a different situation may not see the same effect.
