Run by 3D Medicines · NCT06123754 · Data updated 2026-11-12

This study is testing if adding a new drug called envafolimab to standard chemotherapy can help people with resectable stage III lung cancer do better before and after surgery.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with a confirmed diagnosis of resectable stage IIIA-IIIB NSCLC and good overall health.

Probably not a fit

Patients with certain types of lung cancer, such as neuroendocrine carcinoma or those who have previously received similar immunotherapy treatments, may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This Phase 3 clinical study evaluates the effectiveness and safety of envafolimab combined with platinum-based chemotherapy compared to a placebo with the same chemotherapy in patients with resectable stage IIIA and IIIB non-small cell lung cancer (NSCLC). Approximately 390 participants will be randomly assigned to receive either the experimental treatment or placebo for 3-4 cycles before surgery. Following surgery, participants will continue to receive either envafolimab or placebo. The study aims to assess the major pathological response rate and event-free survival through rigorous follow-up and imaging evaluations.

Why it matters

Potential benefit: If successful, this treatment could improve outcomes for patients with resectable stage III NSCLC.

How similar studies have gone: Other studies have shown promising results with similar immunotherapy approaches in lung cancer, indicating potential for success in this trial.
