Summary

Phase Ib: To observe the safety and tolerability of the combination of SI-B001 and SI-B003, and to determine the recommended dose of phase II clinical study (RP2D) in the indication of locally advanced or metastatic non-small cell lung cancer. Phase II: To evaluate the efficacy of SI-B001+SI-B003 combination with or without chemotherapy in patients with locally advanced or metastatic non-small cell lung cancer.
