To Evaluate the Efficacy and Safety of TQB3728 Tablets in Sequential Maintenance of TQB2450 Injection Therapy in Patients After Sequential or Concurrent Chemoradiation for Locally Advanced Non-small Cell Lung Cancer.

A Randomized, Open Label, Parallel Controlled, Multicenter Phase Ib/II Clinical Trial to Evaluate the Efficacy and Safety of TQB3728 Tablets in Sequential Maintenance of TQB2450 Injection Therapy in Patients After Sequential or Concurrent Chemoradiation for Locally Advanced Non-small Cell Lung Cancer.

It's a Phase Ib/II clinical trial to evaluate the efficacy and safety of TQB3728 tablets in sequential maintenance TQB2450 injection therapy in patients after sequential or concurrent chemoradiation for locally advanced non-small cell lung cancer.

Incidence and severity of adverse events (AEs), the type of dose-limiting toxicity(ies) (DLT[s]) and Recommended phaseII dose(RP2D) were the Phase Ib primary endpoint. Overall response rate (ORR) was the Phase II primary endpoint.
