Brief Summary:
This study is a first-in-human, Phase 1/2, open label study that will evaluate safety and efficacy of ISB 1442 in relapsed/refractory multiple myeloma (R/R MM).

Condition or disease Intervention/treatment Phase
Relapsed/Refractory Multiple Myeloma Drug: ISB 1442 SC injection escalating doses Drug: ISB 1442 SC injection at RP2D Phase 1 Phase 2

Detailed Description:

The study will be conducted in two phases:

  • Phase 1: Dose escalation in R/R MM
  • Phase 2: Dose expansions in select R/R MM

    • Cohort A: R/R MM
    • Cohort B: R/R MM Post-T-Cell Directed Therapy Participants will be treated at escalating dose levels in Phase 1 (dose-escalation phase) of the study. Once the safety of ISB 1442 is confirmed and a Recommended Phase 2 Dose (RP2D) is established in Phase 1 for a given indication, Phase 2 will be initiated for that indication.

Participants will receive ISB 1442, until disease progression, unacceptable toxicity, or any criterion for stopping the study drug or withdrawal from the trial occurs.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 121 participants
Allocation: Randomized
Intervention Model: Sequential Assignment
Intervention Model Description: Participants will be treated at escalating dose levels in Phase 1 (dose-escalation phase) of the study. Once the safety of ISB 1442 is confirmed and a recommended phase 2 Dose (RP2D) is established in Phase 1, Phase 2 will be initiated for that indication. The Phase 2 design uses the Simon two-stage design with stopping rules for lack of activity, as well as stopping rules for toxicity. Participants will receive ISB 1442, until disease progression, unacceptable toxicity, or any criterion for stopping the study drug or withdrawal from the trial occurs.

Arm Intervention/treatment
Experimental: Phase 1: Dose escalation
Participants with R/R multiple myeloma (MM) will be administered ISB 1442 weekly by subcutaneous (SC) injection in each 28-day cycle. Dose escalation will begin with an accelerated titration dose escalation and should certain conversion criteria be met, escalation will convert to the standard (3 + 3) dose escalation
Drug: ISB 1442 SC injection escalating doses
Participants will receive escalating SC doses of ISB 1442

Experimental: Phase 2 (Dose Expansion): Cohort A: R/R Multiple Myeloma
This cohort includes the participants with pathologically confirmed R/R MM and must have received at least 3 prior lines of therapy, including proteasome inhibitors (PIs), immunomodulators (IMiDs), and anti CD38 therapies either in combination or as a single agent; and must not be candidates for regimens known to provide clinical benefit. Participants will receive the recommended Phase 2 Dose (RP2D) of ISB 1442 SC injection determined in Phase 1 of the study for treatment of R/R MM. Each treatment cycle duration is 28 days. The anticipated total duration for each participant will vary, depending on the number of cycles of treatment completed. The treatment phase will extend until participants experience disease progression or unacceptable toxicity, or until any other discontinuation criterion is met.
Drug: ISB 1442 SC injection at RP2D
ISB 1442 SC injection dose regimen at RP2D until participants experience disease progression or unacceptable toxicity, or until any other discontinuation criterion is met

Experimental: Phase 2 (Dose Expansion): Cohort B: R/R MM Post-T-cell-Directed Therapy
This cohort includes the participants with pathologically confirmed R/R MM post T cell-directed therapy and have received prior treatment with proteasome inhibitors (PIs), immunomodulators (IMiDs), and anti-CD38 therapies either in combination or as a single agent; and must have failed at least 3 prior lines of treatment. Participants will receive the RP2D of ISB 1442 SC injection determined in Phase 1 of the study. Each treatment cycle duration is 28 days. The anticipated total duration for each participant will vary, depending on the number of cycles of treatment completed. The treatment phase will extend until participants experience disease progression or unacceptable toxicity, or until any other discontinuation criterion is met.
