Description of intervention(s) / exposure
Treatment: Drugs - ISB 1442 SC injection escalating doses
Treatment: Drugs - ISB 1442 SC injection at RP2D
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
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.
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.

residual disease parameters (i.e., minimal residual disease positive).
2. Participants with MM with disease where the only measurable parameter is plasmacytoma.
3. Received treatment with anti-CD38 antibodies or CD47 targeted therapies within 1 month
of C1D1; systemic anticancer treatments within 14 days before the first dose of study
drug (C1D1) or any investigational products within 5 half-lives of C1D1, whichever is
appropriate to last therapy received. (eg, non-IMP IMiD, proteasome inhibitor could be
considered to be eligible if there is at least 14 days after last dose before C1D1.
