Objective Response Rate (ORR) | 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. | Up to approximately 24 months |
Disease Control Rate (DCR) | 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 \[PD: at least a 20% increase in the sum of diameters of target lesions and an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered PD\]). | Up to approximately 24 months |
Duration of Response (DOR) | 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. | Up to approximately 24 months |
Progression-free Survival (PFS) | The PFS is defined as the time from the participant's first dose of BL-B01D1 to the first date of either disease progression or death, whichever occurs first. | Up to approximately 24 months |
Overall Survival (OS) | The OS is defined as the time from randomization to death (from any cause). | Up to approximately 24 months |
