Overview
Brief Summary
This multi-center, open label phase II clinical study is performed in patients with locally advanced or metastatic EGFR wild-type ALK wild-type non-small cell lung cancer progressed on prior anti-PD-1 mab ± platinum-based chemotherapy. This study is investigating the safety and efficacy of SI-B001 at optimal combination dose with chemotherapy in patients.

Eligibility Criteria
Inclusion Criteria
- •Voluntarily sign informed consent forms and follow program requirements；
- •Male or female;
- •Age: ≥ 18 years;
- •Expected survival time ≥ 3 months;
- •Patients with locally advanced or metastatic EGFR wild-type ALK wild-type lung cancer, disease progression or intolerance after first-line treatment with anti-PD-1/PD-L1 antibody, disease progression or intolerance after first-line treatment with anti-PD-1/PD-L1 antibody and platinum-based chemotherapy, or progression or intolerance after first-line treatment with anti-PD-1/PD-L1 monoclonal antibody;
- •The subject agrees to provide archival tumor tissue samples or fresh tissue samples of the primary tumor or metastases within 6 months; if the subject is unable to provide tumor tissue samples and the subject is unable to provide the gene sequencing report, the subject shall agree to complete the ctDNA EGFR detection during the screening period, and can be assessed by the investigator if other inclusion criteria are met;
- •Must have at least one measurable lesion as defined by RECISTv1.1;
- •Performance status score ECOG0 or 1;
- •Toxicities from prior anticancer therapy have recovered to grade ≤ 2 as defined by NCI-CTCAEv5.0 (except alopecia);
- •No severe cardiac dysfunction, left ventricular score ≥ 50%;
Exclusion Criteria
- •Patients with past use of docetaxel；
- •Prior to signing the informed consent, the gene sequencing or ctDNA testing report of the previous tissue samples indicated the presence of MET 14 exon jump positive, ROS1 rearrangement positive, BRAF V600E mutation positive, NTRK fusion positive, RET rearrangement positive, HER2 mutation positive, HER2 amplification positive, Patients with KRAS G12C mutation positive；
- •Chemotherapy, biotherapy, immunotherapy, radical radiotherapy, and major surgery were used within 4 weeks before the first administration; palliative radiotherapy, targeted therapy (including small-molecule tyrosine kinase inhibitors) and other antitumor therapy were used within 2 weeks;
- •Screening the history of severe heart disease within the first six months, such as: symptomatic congestive heart failure (CHF) ≥2 (CTCAE v5.0) history, New York Heart Society (NYHA) ≥2 heart failure, acute coronary syndrome, etc.;
- •Prolonged QT interval (QTc \> 450 msec in men or 470 msec in women), complete left bundle branch block, and Degree III atrioventricular block;
- •Active autoimmune diseases and inflammatory diseases, such as systemic lupus erythematosus, psoriasis requiring systemic treatment, rheumatoid arthritis, inflammatory bowel disease and Hashimoto's thyroiditis, except for type I diabetes, hypothyroidism controllable by replacement therapy only, skin diseases not requiring systemic treatment (such as vitiligo, psoriasis);
- •Other malignancies diagnosed within 5 years prior to first dose,Exceptions include: radical basal cell carcinoma of the skin, scaly cell carcinoma of the skin, and/or radical resection of carcinoma in situ;
- •Hypertension poorly controlled by two antihypertensive drugs (systolic blood pressure \> 150 mmHg or diastolic blood pressure \> 100 mmHg);
- •Pulmonary disease defined as ≥ grade 3 according to CTCAEv5.0, including resting dyspnea, or requiring continuous oxygen therapy, or patients with a history of interstitial lung disease (ILD);
- •Symptoms of active central nervous system metastases.However, patients with stable parenchymal metastases can be stable, and whether it is stable or not is judged by the investigator;
