Clinical Trial Summary

The purpose of this study is to assess safety, efficacy, pharmacokinetic (PK)/pharmacodynamic (PD), and immunogenicity with ISB 1342 in subjects with relapsed/refractory multiple myeloma.

Description:

This study is an open-label, multi-center, Phase 1 study of ISB 1342 in subjects with relapsed/refractory multiple myeloma refractory to proteasome inhibitors (PIs), immunomodulators (IMiDs), and daratumumab. There will be a dose escalation phase (Part 1) and dose expansion phase (Part 2). In Part 1 of the study, subjects will be treated at escalating dose levels. Once the recommended part 2 dose (RP2D) of ISB 1342 is declared in Part 1, the expansion phase (Part 2) will be initiated at the RP2D.

Recruitment information / eligibility

• Status: Completed
• Enrollment: 81
• Est. completion date: December 15, 2023
• Est. primary completion date: December 15, 2023
• Accepts healthy volunteers: No
• Gender: All
• Age group: 18 Years and older

Eligibility

Inclusion Criteria:

• Documented diagnosis of multiple myeloma with measurable disease (serum, urine, or free light chain) per International Myeloma Working Group (IMWG) criteria, including non-secretory or oligo-secretory multiple myeloma which has relapsed after or is refractory to prior therapies, including proteasome inhibitors (PIs), immunomodulators (IMiDs) and anti-CD38 targeted therapies (daratumumab, isatuximab).

• Eastern Cooperative Oncology Group (ECOG) performance-status score of 2 or less and 1 or less (for France).

• Adequate hematologic, renal, and hepatic functions

• Seronegative for hepatitis B antigen; positive hepatitis B tests can be further evaluated by confirmatory tests, and if viral load is negative, the subject can be enrolled.

• Seronegative for hepatitis C antibody; if positive, then further test for the presence of antigen by hepatitis C virus polymerase chain reaction (HCV PCR). If HCV antigen tests are negative, then the subject can be enrolled.

• Oxygen saturation level =92% on room air.

• Left ventricular ejection fraction (LVEF) =50% and no pericardial or pleural effusion at Screening

Exclusion Criteria:

• Active central nervous system involvement

• Exposure to daratumumab or isatuximab within 2 months prior to the start of study treatment

• Active plasma cell leukemia

• Active infectious disease

• Clinically significant cardiovascular and respiratory conditions

• History of HIV infection

• Subjects requiring prohibited concomitant medications
