Description of intervention(s) / exposure
ISB 1442 is a potential first-in-class CD38 x CD47 bispecific, biparatopic antibody generated using Ichnos’ BEAT® 2.0 technology. ISB 1442 is designed to kill CD38-expressing tumor cells
The Study consists of two parts
Phase 1 (Dose Escalation phase)
Investigational Product (IP): ISB 1442
Dosage Form: Lyophilized powder
Mode of Administration: Subcutaneous (SC) Injection
Dosage frequency: For all cohorts, dosing will occur once on Days 1, 8, 15, and 22 of each 28-day cycle, for a maximum of typically approximately 4 cycles. However, the maximum number of cycles could be endless, as participants may continue on the assigned dose within their cohort until disease progression, intolerability or withdrawal of consent.
Cohort 1: 6 mg of ISB 1442 administered once on Days 1, 8, 15 and 22 of each 28-day cycle
Cohort 2: 20 mg of ISB 1442 administered once on Days 1, 8, 15 and 22 of each 28-day cycle
Cohort 3: 60 mg of ISB 1442 administered once on Days 1, 8, 15 and 22 of each28-day cycle
Cohort 4: 150 mg of ISB 1442 administered once on Days 1, 8, 15 and 22 of each 28-day cycle
Cohort 5: 300 mg of ISB 1442 administered once on Days 1, 8, 15 and 22 of each 28-day cycle
Cohort 6: 600 mg of ISB 1442 administered once on Days 1, 8, 15 and 22 of each 28-day cycle
Cohort 7: 1200 mg of ISB 1442 administered once on Days 1, 8, 15, 22 of each 28-day cycle
Dose escalation will continue until either Maximum Tolerated Dose (MTD) is defined, the maximum planned dose is reached, or a recommended Phase 2 dose (RP2D) is selected.
Decisions with regards to step-up/priming dose levels and schedule will be made by the Safety Monitoring Committee (SMC)
To allow for assessment of safety, the dosing of all patients within each dose level cohort should be staggered with at least 24 hours between each patient. Agreement from the SMC must be obtained before treatment of the next dose escalation cohort can start.
The IP will be administered subcutaneously by authorized site staff once weekly on Days 1, 8, 15, 22 in a 28-day cycle for all cohorts.
Phase 2 (Dose Expansion Phase)
Investigational Product: ISB 1442
Dosage Form: Lyophilized powder
Mode of Administration: Subcutaneous (SC) Injection
About 4-8 weeks after the recommended Phase 2 dose (RP2D) of ISB 1442 is established in Phase 1, Phase 2 expansions will be initiated to further evaluate safety and efficacy of ISB 1422.
The phase 2 of study will enroll two distinct cohorts (Cohort A: Relapsed/Refractory (R/R) Multiple Myeloma (MM) and Cohort B: R/R MM Post-T-Cell-Directed Therapy) of participants.
The participants in each cohort will receive ISB 1442 on day 1, 8, 15 and 22 of each 28-day cycles, for a maximum of typically approximately 12 cycles, however, the maximum number of cycles could be endless, as participants may continue on the assigned Phase 2 dose until disease progression, intolerability or withdrawal of consent.
The IP will be administered subcutaneously by authorized site staff once weekly on Days 1, 8, 15, 22 in a 28-day cycle.
The phase 1 and phase 2 of the study will enroll distinct group of participants.

Phase 1/Phase 2: Characterize immunogenicity of ISB 1442 through percent incidence of anti-drug antibody (ADA), neutralizing antibody (nAb) and titer of ADA. This is composite secondary outcome.
Whole blood sample will be collected for immunogenicity assessment
Timepoint [2] 409207 0

For subsequent cycles: Up to 60 months from initiation of the study, or to last patient dosed, whichever comes first.
Secondary outcome [3] 410134 0
Phase 1: Assess preliminary efficacy of ISB 1442
1. Analysis of time to event endpoints: time to progression (TTP), time to next treatment (TTNT), time to response (TTR), progression free survival (PFS), overall survival (OS), duration of response (DOR) will be performed according to the Kaplan-Meier method and the 95% CIs of the median will be provided.

Time to Progression (TTP) is defined as the time from the date of the first dose to the date of the first documentation of progressive disease as defined by standard disease criteria.
Progression will be assessed by measurement of circulating M-protein (peripheral blood draw), a bone marrow biopsy/aspirate is not required but may be performed as part of standard of care
Time to New Treatment (TTNT) is defined as the time from the date of first dose randomisation to the date of the first dose initiation of the next line of antineoplastic therapy, for any reason. Patients who have not started the second-line therapy will be censored at date of last known to be alive subsequent anti-cancer therapy. New treatment start date will be captured from patient medical records and/or follow-up calls as part of Survival Follow-Up
Time to To Response (TTR) is the time from the date of the first dose to the date of the first documentation of objective response [response of Partial Response or better for MM] as defined by standard disease criteria. Response to treatment will be assessed by measurement of circulating M-protein (peripheral blood draw) and for patients with extramedullary disease at enrollment, the same imaging as performed for screening; a bone marrow biopsy/aspirate biopsy to confirm response for patients with a response of very good partial response (VGPR) or better.
Progression Free Survival (PFS) is defined as the time from the date of the first dose administration to the date of first documentation of progressive disease or death due to any cause, whichever occurs first. Progressive disease will be determined by standard disease criteria. Patients without documentation of progressive disease will be censored at the date of the last response assessment. Progression will be assessed by measurement of circulating M-protein (peripheral blood draw), a biopsy is not required but may be performed as part of standard of care.
Overall Survival (OS) is defined as the time from the date of randomisation to the date of death. Patients without documentation of death at the time of analysis will be censored at the date last known to be alive. Survival will be captured from patient medical records and/or follow-up calls as part of Survival Follow-Up
Duration of Response (DOR) is the time from the date of first documentation of a Partial Response (PR) or better to the date of first documentation of progressive disease for responders (PR or better). Responders without documentation of progressive disease will be censored at the date of last response assessment that is stable disease or better. Patients who present with response to treatment will continue to be assessed by circulating M-protein (peripheral blood draw), patients with a complete response (CR) or better and are minimal residual disease (MRD) negative will be assessed for MRD status every six months (bone marrow aspirate)

2. Investigator-assessed overall response rate (ORR) and complete response rate (CRR) based on International Myeloma Working Group (IMWG) for Multiple Myeloma with 95% confidence intervals (Cis) will be presented.
This is a composite secondary outcome.
