Study Endpoints

Primary Endpoints

Incidence of Dose Limiting Toxicities (DLTs)- Dose escalation (Part A)
Cycle 1 (28 days)

The incidence of DLTs will be evaluated using NCI CTCAE version 5.0 criteria.

Overall response rate (ORR) - Dose optimization (Part B)
24 months after the Last Participant In (LPI)

ORR is defined as the proportion of participants with sCR, CR, VGPR, and PR assessed as per Investigator according to the 2016 IMWG response criteria.

Secondary Endpoints

Number of participants with treatment emergent adverse events (TEAEs), injection related reactions (IRRs), injection site reactions (ISRs), serious adverse events (SAEs), adverse event of special interests (AESIs)
From the signing of informed consent to 30 days after the date of the last study treatment administration i.e., approximately 5 years
Change from baseline in laboratory abnormalities
