Group Intervention Description Study treatment BL-B01D1 Participants received SI-B003 and BL-B01D1+SI-B003 in the first cycle (3 weeks). Participants who had a clinical benefit could receive additional cycles of additional treatment. Administration will be discontinued because of disease progression or intolerable toxicity or for other reasons. Study treatment SI-B003 Participants received SI-B003 and BL-B01D1+SI-B003 in the first cycle (3 weeks). Participants who had a clinical benefit could receive additional cycles of additional treatment. Administration will be discontinued because of disease progression or intolerable toxicity or for other reasons.
- Primary Outcome Measures
Name Time Method 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.
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 SI-B003.
- Secondary Outcome Measures
Name Time Method Treatment-Emergent Adverse Event (TEAE) Up to approximately 24 months TEAE is defined as any adverse and unexpected change in body structure, function, or chemistry or any exacerbation of an existing condition (i.e., any clinically significant adverse change in frequency and/or intensity) during treatment. The type, frequency, and severity of TEAE will be assessed during treatment.
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 \[PD: at least a 20% increase in the sum of diameters of target lesions and an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered PD\]).
Progression-free survival (PFS) Up to approximately 24 months The PFS is defined as the time from the first dose of medication to disease progression or death, whichever occurred first.
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.
