Consent to treatment; 5. ECOG score: 0-1; 6. Previous PD-1 therapy failure; 7. At least one measurable lesion (≥10 mm on CT scan for non-nodal lesions and ≥15 mm on CT scan for nodal lesions according to RECIST criteria).
• Have adequate organ function: 9. Blood routine: Absolute Neutrophil Count (ANC) 1.5×109/L, Platelet (PLT) ≥70×109/L, Hemoglobin (HGB) ≥80g/L; 10.

Estimated survival time ≥3 months; 14. Contraception during treatment 15. Ability to adhere to study access schedules and other protocol requirements.

You may not qualify if…
