- •Expected survival time ≥3 months;
- •Patients with extensive-stage small-cell Lung cancer confirmed by histopathology and/or cytology (according to Veterans Administration Lung Study Group (VALG) staging);
- •Cohort_A cohort of patients with extensive-stage small cell lung cancer who had failed or were intolerant to 3 or more lines of systemic antitumor therapy. The so-called intolerance refers to the patients who have received standard treatment and have grade 3-4 adverse reactions, and the patients refuse to continue the original regimen.
- •Cohort_B Stage I subjects with previous failure or intolerance to standard therapy for extensive-stage small cell lung cancer;
- •Cohort_B Stage II patients who have not received any previous systemic anti-tumor therapy for extensive-stage small cell lung cancer;
- •Consent to provide archival tumor tissue specimens (10 unstained sections (anti-slip) surgical specimens (thickness 4-5μm)) or fresh tissue samples from primary or metastatic lesions within 3 years. If participants cannot provide tumor tissue samples, they can be enrolled if they meet other inclusion and

- •Other malignant tumors that have progressed or require treatment within 5 years before the first dose, except for radical basal cell carcinoma of the skin, squamous cell carcinoma of the skin, superficial bladder cancer, radical resection of carcinoma in situ, such as carcinoma in situ of the breast, and prostate cancer; Notes: Patients with localized low-risk prostate cancer (defined as stage ≤T2a, Gleason score ≤6, and PSA < 10ng/mL at prostate cancer diagnosis (as measured) who had received radical treatment and no biochemical recurrence of prostate specific antigen (PSA) were eligible to participate in this study).

Study treatment
Experimental
Participants received BL-B01D1 monotherapy, SI-B003 monotherapy or BL-B01D1 plus SI-B003 dual therapy 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.

结局指标
主要结局
Objective response rate (ORR)
时间窗: 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)
时间窗: 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.
次要结局
- Treatment-Emergent Adverse Event (TEAE)(Up to approximately 24 months)
- Progression-free survival (PFS)(Up to approximately 24 months)
