Summary

A Phase 2 Study to Evaluate Safety and Efficacy of Teclistamab-, Talquetamab-, and JNJ-79635322-based Combination Regimens in Participants with Newly Diagnosed Transplant Eligible Multiple Myeloma OBJECTIVES: To evaluate the safety and tolerability of teclistamab-, talquetamab-, and JNJ-79635322-based combination regimens over the entire treatment phase for each arm, in participants with ND-TEMM To evaluate the efficacy of teclistamab- and talquetamab-based combination regimens as induction and post-transplant maintenance treatments; JNJ-79635322-based combinations as induction and as replacement for HDT+ASCT following induction; and teclistamab in combination with talquetamab

Detailed description

OVERALL DESIGN: 160 participants will be enrolled with 10 participants in Arm A, 20 participants in Arm A1, 20 participants in Arm B, 10 participants in Arms C and 10 in C2, 20 participants in Arm D, 10 participants in each Arm E, E1 and optionally F and F, and 20 participants in Arm G. Cohorts may be further expanded. Arms A, A1, B, D, E, E1, F, F1 will receive Induction therapy of 6 cycles (28-days each): Treatment: Tec-DRd (Arm A, A1), Tec-DVRd (Arm B), Tal-DRd (Arms E, E1), Tal-DVRd (Arms F, F1) followed by HDT and a single ASCT according to local SoC treatment. Thereafter a Maintenance Therapy of maximum 18 cycles with either Tec-D (Arms A, A1, B, E, F) or Tal-D (E1, F1) is performed. Arm D will receive 6 28-days cycles Tec-DVRd induction followed by 18 cycles Tec-Tal. Arm G will receive 6 28-day cycles of JNJ-79635322-DRd induction, followed by JNJ-79635322-D. No HDT ASCT will be performed in Arm D and Arm G. In Arm C and C2 participants will enter the study for maintenance treatment of 18 cycles with Tec-D (Arm C) or Tal-DR (Arm C2) , after induction, HDT and ASCT according to local SoC (outside of the study). Participants will receive maintenance treatment or following induction treatment (Arm D and G) for a maximum of 18 cycles or until confirmed progressive disease, death, intolerable toxicity, loss to follow-up, or consent withdrawal, whichever comes first. An optional end of treatment is possible for patients who have 12 months sustained MRD negativity. Periodic safety evaluations will be conducted to ensure that treatment is safe and tolerable. Upon treatment discontinuation, an EOT Visit will be conducted. Thereafter, the participant will continue in the Follow-up Phase until death, withdrawal of consent, loss to follow-up, or end of the study, whichever occurs first.
