Conditions
Brief summary
This phase II study is designed to investigate the efficacy and safety of BL-B01D1 monotherapy, SI-B003 monotherapy, and BL-B01D1+SI-B003 combination therapy in patients with extensive-stage small cell lung cancer.

Inclusion criteria
1. All subjects voluntarily participated in the study and signed informed consent; 2. Male or female aged ≥18 years and ≤75 years; 3. Expected survival time ≥3 months; 4. ECOG 0-1; 5. Patients with extensive-stage small-cell Lung cancer confirmed by histopathology and/or cytology (according to Veterans Administration Lung Study Group (VALG) staging); 1. 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. 2. Cohort\_B Stage I subjects with previous failure or intolerance to standard therapy for extensive-stage small cell lung cancer; 3. Cohort\_B Stage II patients who have not received any previous systemic anti-tumor therapy for extensive-stage small cell lung cancer; 6. 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
Exclusion criteria
, after the evaluation of the investigator; 7. Must have at least one measurable lesion according to RECIST v1.1 definition; Lesions that had been previously treated with radiation could be included in a measurable lesion only if there was definite disease progression after radiation therapy. 8. Organ function level must meet the following criteria: 1. Blood routine: hemoglobin (HGB) ≥ 90g/L; Absolute neutrophil count (NEUT) ≥ 1.5×10 9 /L; Platelet count (PLT) ≥ 100×10 9 /L; 2. Renal function: creatinine (Cr) ≤1.5 ULN, or creatinine clearance (Ccr) ≥50 mL/min (according to Cockcroft and Gault formula). 3. Liver function: total bilirubin (TBIL≤1.5 ULN), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were all ≤2.5 ULN, and AST and ALT were both ≤5.0 ULN when liver metastasis was present; 4. coagulation function: international normalized ratio (INR) ≤1.5 and activated partial thromboplastin time (APTT) ≤1.5ULN; 5. no severe cardiac dysfunction with left ventricular ejection fraction ≥50%; 6. proteinuria ≤2+ or ≤1000mg/24h; 9. Toxicity of previous antineoplastic therapy has returned to ≤ grade 1 as defined by NCI-CTCAE v5.0 (except for asymptomatic laboratory abnormalities such as ALP elevation, hyperuricemia, and hyperglycemia, as judged by the investigator, and toxicity without safety risk, such as alopecia, grade 2 peripheral neurotoxicity, or decreased hemoglobin ≥90g/L, as judged by the investigator); 10. For premenopausal women with childbearing potential, a pregnancy test must be performed within 7 days before the start of treatment, the serum or urine pregnancy test must be negative, and the patient must not be lactating; All enrolled patients should take adequate barrier contraception during the whole treatment cycle and for 6 months after the end of treatment.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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. |
| 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 \[PD: at least a 20% increase in the sum of diameters of target lesions and an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered PD\]). |
| 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. |
| 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. |
