kn046 plus lenvatinib in subject with advanced non-small cell lung cancer in the failure of anti-pd-(l)1 agent

Conditions: Advanced Non-small Cell Lung Cancer

Summary: this is a phase 2/3, multicenter, randomized, open, positive-controlled study of patients with advanced non-small cell lung cancer whose disease has progressed after prior anti-pd-(l)1 therapy. subjects should have documented progressive disease during prior treatment with first- or second-line pd-(l)1 and platinum-containing dual-agent chemotherapy.subjects will be randomized to two treatment groups in a 1:1 ratio. treatment group: kn046 5mg/kg q3w + lenvatinib recommended for phase iii dose (rp3d) every day. control group: docetaxel 75mg/m2 q3w .
