Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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-M08D1. |
| 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| T1/2 | Up to approximately 24 months | T1/2 is defined as the time required for the plasma concentration of a drug to decrease by 50% during the elimination phase. |
| 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 | Clearance (CL) is the volume of plasma from which a drug is completely removed per unit time. |
| Progression-free Survival (PFS) | Up to approximately 24 months | Progression-free survival (PFS) as assessed by BICR is defined as the time between the date subjects were randomized and the first observation of disease progression (based on BICR's image-based assessment) or death. |
| Disease Control Rate (DCR) | Up to approximately 24 months | Disease Control Rate (DCR) : Percentage of all randomized subjects who rated the best overall response (BOR) as complete response (CR), partial response (PR), and disease stabilization (SD) according to RECIST 1.1 criteria. |
| Duration of Response (DOR) | Up to approximately 24 months | Duration of Response (DOR) is defined as the period from the date when tumor response is first recorded to the date when objective tumor progression is first recorded or the date of death. |
| 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-M08D1 . The type, frequency and severity of TEAE will be evaluated during the treatment of BL-M08D1. |
| Cmax | Up to approximately 24 months | Cmax is defined as the maximum observed drug concentration in plasma after administration. |
| Ctrough | Up to approximately 24 months | Ctrough is defined as the lowest serum concentration prior to the next dose will be administered. |
| Tmax | Up to approximately 24 months | Tmax is defined as the time required to reach the maximum drug concentration in plasma following drug administration. |
| Anti-drug Antibody (ADA) | Up to approximately 24 months | Frequency of anti-BL-M08D1 antibody (ADA) will be investigated. |
