Group Intervention Description BL-M24D1 BL-M24D1 Participants receive BL-M24D1 as intravenous infusion for the first cycle (2 weeks). Participants with clinical benefit could receive additional treatment for more cycles. The administration will be terminated because of disease progression or intolerable toxicity occurring or other reasons.
- Primary Outcome Measures
Name Time Method Phase Ia: Dose limiting toxicity (DLT) Up to 28 days after the first dose DLTs are assessed according to NCI-CTCAE v5.0 during the first cycle and defined as occurrence of any of the toxicities in DLT definition if judged by the investigator to be possibly, probably or definitely related to study drug administration.
Phase Ia: Maximum tolerated dose (MTD) Up to 28 days after the first dose MTD is defined as the highest dose level at which no more than 1 in 6 participants experienced a DLT during the first cycle.
Phase Ib: Recommended Phase II Dose (RP2D) Up to approximately 24 months The RP2D is defined as the dose level chosen by the sponsor (in consultation with the investigators) for phase II study, based on safety, tolerability, efficacy, PK, and PD data collected during the dose escalation study of BL-M24D1.
- Secondary Outcome Measures
Name Time Method Treatment-Emergent Adverse Event (TEAE) Up to approximately 24 months TEAE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally emerging, or any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition during the treatment of BL-M24D1. The type, frequency and severity of TEAE will be evaluated during the treatment of BL-M24D1.
Cmax Up to approximately 24 months Maximum serum concentration (Cmax) of BL-M24D1 will be investigated.
Tmax Up to approximately 24 months Time to maximum serum concentration (Tmax) of BL-M24D1 will be investigated.
T1/2 Up to approximately 24 months Half-life (T1/2) of BL-M24D1 will be investigated.
AUC0-t Up to approximately 24 months AUC0-t is defined as area under the serum concentration-time curve from time 0 to the time of the last measurable concentration.
CL (Clearance) Up to approximately 24 months CL in the serum of BL-M24D1 per unit of time will be investigated.
Ctrough Up to approximately 24 months Ctrough is defined as the lowest serum concentration of BL-M24D1 prior to the next dose will be administered.
ADA (anti-drug antibody) Up to approximately 24 months Frequency of anti-BL-M24D1 antibody (ADA) will be investigated.
Phase Ib: Objective Response Rate (ORR) Up to approximately 24 months ORR is defined as the percentage of participants, who has a CR (disappearance of all target lesions) or PR (at least a 30% decrease in the sum of diameters of target lesions). The percentage of participants who experiences a confirmed CR or PR is according to RECIST 1.1.
Phase Ib: Disease Control Rate (DCR) Up to approximately 24 months The DCR is defined as the percentage of participants who has a CR, PR, or Stable Disease (SD: neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease \[PD: at least a 20% increase in the sum of diameters of target lesions and an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered PD\]).
Phase Ib: Duration of Response (DOR) Up to approximately 24 months The DOR for a responder is defined as the time from the participant's initial objective response to the first date of either disease progression or death, whichever occurs first.
