The Efficacy and Safety of Adjuvant Immunotherapy After Pathological Complete Response Following Neoadjuvant Chemoimmunotherapy in Patients with Resectable NSCLC

The Efficacy and Safety of Adjuvant Immunotherapy After Pathological Complete Response Following Neoadjuvant Chemoimmunotherapy in Patients with Resectable NSCLC: a Prospective Real-World Study

This is a prospective, observational, multicenter real-world study aiming to investigate the efficacy and safety of NSCLC patients with or without adjuvant immunotherapy who have achieved pathologic complete remission after neoadjuvant immunotherapy.

Inclusion Criteria:

1. 18 years ≤ age ≤ 80 years;
2. Histologically or cytologically confirmed NSCLC;
3. Resectable stage IB, II, IIIA, or IIIB (N2) NSCLC according to the staging criteria of the American Joint Committee on Cancer (8th edition);
4. Eastern Cooperative Oncology Group (ECOG) performance status score 0-1 at baseline;
5. With measurable or evaluable diseases according to the Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST 1.1) at baseline;
6. Achieving pathological complete response (pCR) after three cycles of neoadjuvant chemoimmunotherapy, which was assessed by independent pathological examination of surgical specimens;
7. With or without adjuvant immunotherapy postoperatively;
8. Signed and dated written informed consent provided by the patient prior to admission to the study.

Exclusion Criteria:

1. EGFR or ALK aberrations positive;
2. With primary/secondary immunodeficiency diseases or symptomatic interstitial lung diseases;
3. With a condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone or equivalents) or other immunosuppressive medications within 14 days of study drug administration;
4. With other active malignant tumors currently receiving cancer therapy (chemotherapy, radiation therapy, immunotherapy, or biologic therapy) or investigational anti-cancer drugs;
5. Receipt of other investigational drugs during the observation period;
6. Unable to follow the procedures required in the protocol due to any medical, mental or psychological conditions.
