About
This study aims to incorporate circulating tumor DNA (ctDNA)-minimal residual disease (MRD) to personalize the administration of consolidation toripalimab therapy in resected stage IB-IIIA non-small-cell lung cancer (NSCLC) after adjuvant therapy. Toripalimab is a humanized monoclonal antibody for human programmed cell death protein 1. Toripalimab was approved as a consolidation treatment after perioperative therapy in combination with chemotherapy for resectable stage III NSCLC.
Full description
Most patients with stage IB-IIIA non-small cell lung cancer (NSCLC) are managed with surgery, follow by standard-of-care adjuvant platinum-based chemotherapy. However, postoperative recurrence rates remain high. Recent years, the role of checkpoint inhibitors has been proven to be effective in patients with advanced NSCLC, and even in patients with resectable NSCLC. Emerging data supports the use of consolidation checkpoint inhibitors therapy in localized NSCLC. Based on the results from Neotorch trial, consolidation toripalimab therapy led to a significant improvement in event-free survival for patients with resectable NSCLC. However, not all patients may benefit from consolidation therapy. Circulating tumor DNA (ctDNA) has emerged as a promising biomarker for early detection of minimal residual disease (MRD) in cancer surveillance. There is a critical need to identify MRD after curative therapies to determine which patients may benefit from consolidation toripalimab therapy. The aim of this study is to explore whether observation follow-up for patients with negative ctDNA after adjuvant therapy has a non-inferior prognosis for patients with positive ctDNA and received consolidation toripalimab therapy. This study aims to incorporate ctDNA-MRD to personalize the administration of consolidation toripalimab therapy for completely resected stage IB-IIIA NSCLC (without EGFR or ALK alterations for nonsquamous NSCLC).

Exclusion criteria
- Not R0 resection, or metastatic disease.
- Subjects with known EGFR sensitive mutations or ALK translocation, EGFR and ALK mutation status needs to be identified for the subjects with non-squamous NSCLC;
- Previous treatment with systemic antitumor therapy for NSCLC;
- Severe allergic reaction to other monoclonal antibodies;
- Subjects with any known or suspected autoimmune disorder or immunodeficiency, with the following exceptions: hypothyroidism, hormone therapy is not needed, or well controlled at physiological dose; controlled type I diabetes;
- Uncontrolled active hepatitis B (defined as positive hepatitis B surface antigen in screening period with HBV-DNA detected higher than the upper limit of normal at the clinical laboratory of the study center); active hepatitis C (defined as positive hepatitis C surface antibody in screening period and positive HCV-RNA);
- Vaccination of live vaccine within 30 days prior to the first dose;
- Evidence of clinically active interstitial lung disease;
- Known history of testing positive for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS);
