Neoadjuvant atezolizumab with carboplatin and paclitaxel followed by atezolizumab maintenance for Stage III non-small cell lung cancer

Official title: Phase II Clinical Trial of Chemotherapy + Atezolizumab for Stage IIIa and IIIb Non-small Cell Lung Cancer Followed by Atezolizumab as Adjuvant Treatment After Surgery and Atezolizumab as Maintenance Treatment for Non-resected Patients After Chemoradiotherapy

Run by Fundación GECP · NCT07153445 · Data updated 2026-11-12

This trial tests whether giving atezolizumab with carboplatin and paclitaxel before possible surgery, then continuing atezolizumab afterward, helps people with stage III non-small cell lung cancer stay free of disease progression longer.

Is this trial a fit for you?

Likely a good fit

Adults over 18 with previously untreated stage IIIA–IIIB NSCLC, no distant metastases, ECOG performance status 0–1, and adequate organ and lung function are the intended candidates.

Probably not a fit

Patients with distant metastatic disease, poor performance status, inadequate organ or lung function, or inability to tolerate platinum-based chemotherapy are unlikely to benefit.

What this trial studies

ATHENEA is an open-label, multicenter phase II trial enrolling 97 adults with previously untreated stage IIIA or IIIB non-small cell lung cancer. Participants receive three cycles of atezolizumab combined with paclitaxel and carboplatin as neoadjuvant/induction therapy, after which a multidisciplinary team decides whether a patient proceeds to surgery. Following that decision, patients receive different post-induction treatments and enter long-term follow-up, with progression-free survival as the primary endpoint. The planned overall timeline is about 10 years including treatment, five years of follow-up, and study close-out.

Why it matters

Potential benefit: If successful, this approach could prolong the time patients live without their cancer worsening and increase the chance that some can have curative surgery.

How similar studies have gone: Other trials combining PD-1/PD-L1 inhibitors with chemotherapy in the perioperative setting have produced promising pathologic responses and disease-free survival signals, though long-term survival benefits are still being established.
