A Study Comparing BL-B01D1 Combined With Tislelizumab Versus Platinum-containing Chemotherapy Combined With Tislelizumab as First-line Treatment in Patients With Extensive-stage Small Cell Lung Cance Phase 3 562 Randomized Open-Label

Not yet recruiting
Clinical Trial NCT07502300 is designed to study Treatment for Extensive-stage Small-cell Lung Cancer. This Phase 3 interventional study is not yet recruiting. Enrollment is planned to begin on April 1, 2026 until the study accrues 562 participants. Led by Sichuan Baili Pharmaceutical Co., Ltd., this study is expected to complete by December 1, 2029. The latest data from ClinicalTrials.gov was last updated on March 30, 2026.
Brief Summary
This trial is a registrational Phase III, randomized, open-label, multicenter study to compare the efficacy and safety of BL-B01D1 in combination with tislelizumab versus platinum-based chemotherapy in combination with tislelizumab in first-line patients with extensive-stage small cell lung cancer.

Arms / Interventions
Participant Group/ArmIntervention/Treatment
ExperimentalBL-B01D1+Tislelizumab
Participants receive BL-B01D1+Tislelizumab in the first cycle (3 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.
BL-B01D1
Administration by intravenous infusion for a cycle of 3 weeks.
Tislelizumab
Administration by intravenous infusion for a cycle of 3 weeks.
Active ComparatorCarboplatin+Etoposide +Tislelizumab
Participants receive Carboplatin+Etoposide +Tislelizumab in the first cycle (3 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.
Tislelizumab
Administration by intravenous infusion for a cycle of 3 weeks.
Carboplatin
Administration by intravenous infusion for a cycle of 3 weeks.
Etoposide
Administration by intravenous infusion for a cycle of 3 weeks.
Primary Outcome Measures
Outcome MeasureMeasure DescriptionTime Frame
Overall survival (OS)
Overall survival (OS) is defined as the time between the subject's randomization date and subject's death.
Up to approximately 24 months
Secondary Outcome Measures
Outcome MeasureMeasure DescriptionTime Frame
Progression-free survival (PFS)
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.
Up to approximately 24 months
Objective Response Rate (ORR)
Objective response rate (ORR) is defined as the number of CR and PR in the treatment and control groups divided by the number of that group in the full analysis set (FAS).
Up to approximately 24 months
Disease Control Rate (DCR)
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.
Up to approximately 24 months
Duration of Response (DOR)
Duration of Response (DOR) : 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.
Up to approximately 24 months
Treatment Emergent Adverse Event (TEAE)
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-B01D1. The type, frequency and severity of TEAE will be evaluated during the treatment of BL-B01D1.
Up to approximately 24 months
Anti-drug antibody (ADA)
Frequency of anti-BL-B01D1 antibody (ADA) will be investigated.
Up to approximately 24 months
