envafolimab combined with chemotherapy and recombinant human endostatin in the first-line treatment of sq-nsclc

Conditions: Squamous Non-small Cell Lung Cancer

Summary: this is a prospective, single arm, multicenter phase ii study aimed at evaluating the efficacy and safety of envafolimab combined with standard platinum containing dual drug chemotherapy and recombinant human endostatin in patients with advanced (stage iiib-iv) squamous non-small cell lung cancer.
