Brief summary
This multi-center, open label Phase II/III clinical study is performed in patients with locally advanced/metastatic NSCLC progressed on prior EGFR-TKI treatment or with non TKI-sensitizing mutation or patients with EGFR exon20ins mutation. This study is investigating the safety and efficacy of SI-B001 at monotherapy RP2D or lower combined with Osimertinib in patients with locally advanced or metastatic NSCLC.
Interventions
SI-B001 is administered by intravenous drip once weekly (QW). 120 min ± 10 min after the first intravenous drip, if the infusion reaction is tolerable during the first dose, the subsequent infusion can be completed within 60-120 min (unless agreed or required by the investigator, the infusion time can be extended).
Osimertinib is administered at the recommended dose of 80mg daily.

Patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) confirmed by histopathology and/or cytology, T790M-negative, Exon20ins mutation resistant to the third generation EGFR TKI after the first or second line treatment, or resistance to the first or second generation TKI after the first line treatment; 6. Consent to provide an archived tumor tissue specimen or fresh tissue sample (an FFPE block or approximately 6-12 white slides with a size of 5μm) from the primary or metastatic tumor within 6 months of the date of consent.

Exclusion criteria
after evaluation by investigators. 7. Must have at least one measurable lesion as defined by RECISTv1.1; 8. Performance status score ECOG0 or 1; 9. Toxicity from previous antineochemical therapy has returned to grade 1 or less as defined by NCI-CTCAE v5.0 (asymptomatic laboratory abnormalities such as elevated ALP, hyperuricemia, elevated serum amylase/lipase, and elevated blood glucose were considered by the investigator, and toxicity with no safety risk was judged by the investigator; Except for alopecia, grade 2 peripheral neurotoxicity, and hypothyroidism stable with hormone replacement therapy). 10. No severe cardiac dysfunction, left ventricular score ≥ 50%; 11. The level of organ function must meet the following criteria: 1. Bone marrow function: Absolute neutrophil count (ANC) ≥ 1.5 × 10\^9/L, platelet count ≥ 80 × 10\^9/L, hemoglobin ≥ 90 g/L; 2.

Renal function: creatinine (Cr) ≤ 1.5ULN, or creatinine clearance (Ccr) ≥ 50 mL/min (according to CockcroftandGault formula). 12. Coagulation function: international normalized ratio (INR) ≤ 1.5 × ULN, and activated partial thromboplastin time (APTT) ≤ 1.5ULN; 13. Urine protein ≤ 2 + (measured by dipstick) or \< 1000 mg/24 h (urine); 14. Premenopausal women of childbearing potential must have a negative serum or urine pregnancy test 7 before starting treatment and must be non-lactating; all patients (male or female) should take adequate barrier contraception measures throughout the treatment cycle and 6 months after the end of treatment.
