About

Phase 2 Study to Evaluate Safety and Efficacy of Teclistamab- and Talquetamab-based Combination Regimens in Participants with Newly Diagnosed Transplant Eligible Multiple Myeloma

OBJECTIVES:

The primary objective is to evaluate the safety and tolerability of teclistamab- and talquetamab-based combination regimens over the entire treatment phase for each arm, in participants with ND-TEMM

The key secondary objective is to evaluate the efficacy of teclistamab- and talquetamab-based combination regimens as induction and post-transplant maintenance treatments, and teclistamab in combination with talquetamab as replacement for HDT+ASCT following induction

Full description

OVERALL DESIGN:

130 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 F1. 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 Tec-DVRd induction followed by 18 cycles Tec-Tal. No HDT ASCT will be performed in Arm D.

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) 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.

Post-ASCT consolidation is permitted for up to 2 cycles as long as the total number of induction plus consolidation cycles does not exceed 6.

   3 Must have received only one line of therapy and achieved at least a PR as per IMWG 2016 without evidence of progression at the time of enrollment.

   4. Must have received HDT and ASCT within 12 months of the start of induction therapy and be within 6 months of the last ASCT (7 months for participants who received consolidation) at the time of enrollment.

   Exclusion Criteria:

   • Seropositive for HIV, HEP B, Active Hep C infection (details see protocol).
   • COPD with a FEV1 <50% of predicted normal.
   • Moderate /severe persistent asthma within the past 2 years or any uncontrolled asthma. Exclude if FEV1 <50% of predicted normal.
   • Concurrent medical or psychiatric condition or disease that is likely to interfere with study procedures, or that in the investigators opinion would constitute a hazard for participants.
   • Contraindications or life-threatening allergies, hypersensitivity, or intolerance to any study drug/excipients.
   • Pregnant, breastfeeding, or planning to become pregnant while enrolled in this study or within 6 months after the last dose of any study treatment regimen.

   Arm A, A1, B, D, E, E1, F, F1

   • Prior or current systemic therapy or stem cell transplant for any plasma cell dyscrasia, with the exception of emergency use of a short course (equivalent of dexamethasone 40 mg/day for a maximum 4 days) of corticosteroids before treatment.

   • Arm B only: Peripheral neuropathy or neuropathic pain Grade 2 or higher as defined by the NCI-CTCAE Version 5.

   Due to a potential interaction with bortezomib, received a strong CYP3A4 inducer within 5 half-lives prior to enrollment

   Arm C and C2

   • Discontinued treatment due to any AE related to lenalidomide as determined by the investigator.

   • Progressed on multiple myeloma therapy at any time prior to screening.

   • Received a cumulative dose of corticosteroids equivalent to ≥40 mg of dexamethasone within the 14 day period before the start of study treatment administration.
   • Intolerant to the starting dose of lenalidomide (10 mg).
