A Phase 1/2, First-in-Human, Multicenter, Open-Label, Dose Escalation and Dose-Expansion Study of Single-Agent ISB 1442 in Patients with Relapsed/Refractory Multiple Myeloma (ENMCC - Hall D) - Nov 4, 2022 - Abstract #ASH2022ASH_6398; P1/2 Hence, an enhanced CD38 targeted therapy that unleashes the innate immune cell mediated tumor killing potential and overcomes daratumumab resistance mechanisms may present a unique opportunity to treat MM...Due to low-affinity binding to CD47, ISB 1442 engages CD47 efficiently only upon CD38 binding (avidity-induced binding), thereby reducing the potential for on-target, off-tumor effects, and it does not cause any detectable RBC depletion in vitro compared to magrolimab (Figure 2)...The study is currently open for enrollment. Clinicaltrials.gov identifier: NCT05427812.

Enrollment open: Phase 1/2 Study of ISB 1442 in Relapsed/Refractory Multiple Myeloma (clinicaltrials.gov) - Oct 14, 2022 P1/2, N=121, Recruiting, Based on its unique design and multiple mechanisms of action, ISB 1442 is anticipated to have antitumor activity in AML and T-ALL patients in a single antibody relative to anti-CD38 or anti-CD47 monoclonal antibodies as well as their combination.

A multispecific antibody platform for optimal engineering of multiple myelomaimmunotherapies. () - May 9, 2022 - Abstract #CIMT2022CIMT_156; P1 In summary, we report two novel approaches for the treatment of MM using the BEAT technology to co-target either CD38 and CD3, or CD38 and CD47. The designs of ISB 1342 and ISB 1442 are anticipated to enhance antitumor activity in MM patients by overcoming primary and acquired mechanisms of resistance.
