Clinical Study Results | TECVAYLI® (teclistamab-cqyv) HCP


TECVAYLI®, the first bispecific BCMA × CD3 T-cell engager, was evaluated
in the MajesTEC-1 trial1,2

The efficacy of TECVAYLI® was evaluated in 110 patients with relapsed or refractory multiple myeloma in the single-arm, open-label, multi-center, phase 1/2 MajesTEC-1 trial. Patients had received at least 3 therapies, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody.1

Primary Endpoint: ORR3 Key Secondary Endpoints: DOR, TTR3


Patients with a range of characteristics, including those who were heavily pretreated, were studied in MajesTEC-11

  • Median prior lines of therapy: 5 (range: 2-14)
  • 78% of patients had received ≥4 prior lines of therapy
  • 100% of patients had received prior therapy with a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody
  • 76% were triple-class refractory (refractory to a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody)
  • 81% of patients received prior stem cell transplantation

In MajesTEC-1, TECVAYLI® delivered an ORR of 61.8%, with 57.3% of patients achieving a deep response of VGPR or better1,4*

61.8% ORR was demonstrated in the MajesTEC-1 trial
28.2% ≥CRwas demonstrated in the MajesTEC-1 trial

*Efficacy results were based on ORR as determined by the Independent Review Committee (IRC) assessment using International Myeloma Working Group (IMWG) 2016 criteria.




TECVAYLI® provided a median time to first response of 1.2 months1


(range: 0.2-5.5 months)

With a median follow-up of 7.4 months among responders, estimated DOR rates with TECVAYLI® were1:

90.6% of patients (95% CI: 80.3%-95.7%)
continued to respond at 6 months

6 months

66.5% of patients (95% CI: 38.8%-83.9%)
continued to respond at 9 months

9 months

Median DOR not yet reached (DOR: 9.0 months; not estimable; 95% CI)

BCMA, B-cell maturation antigen; CD3, cluster of differentiation 3; CD38, cluster of differentiation 38; CI, confidence interval; CNS, central nervous system; CR, complete response; del, deletion; DOR, duration of response; ECOG, Eastern Cooperative Oncology Group; ISS, International Staging System; ORR, overall response rate; PR, partial response; sCR, stringent complete response; t, translocation; TTR, time to response; VGPR, very good partial response.
