Cryoablation with or Without Serplulimab in Treating Patients with Stage I-IIA Non-small Cell Lung Cancer

Официальное название

Randomized Clinical Trials Comparing Immunotherapy Plus Cryoablation (I-CA) Versus Cryoablation Alone for Stage I, Selected Stage IIa, Non-Small Cell Lung Cancer

Обзор

Cryoablation is a minimally invasive technique that utilizes very low temperature to eliminate tumour cells for patients ineligible for surgery. It has been reported that cryoablation may enhance immune response and synergize with immunotherapy. This study is a multicenter, randomized, controlled, exploratory trial, and is expected to enroll a total of 134 patients. The enrolled patients were stage Ia, Ib, or IIa lung cancer with negative driver gene mutations, who are considered high-risk for surgery or refuse surgery based on multidisciplinary evaluation. Eligible patients will be randomly assigned in a 1:1 ratio to receive either cryoablation alone (CA group) or cryoablation combined with immunotherapy (I-CA group). The study aims to evaluate the safety and clinical benefits of combining immunotherapy with cryoablation in the treatment of early-stage NSCLC by comparing progression-free survival (PFS), objective response rate (ORR), overall survival (OS), and the incidence of adverse events between the two groups.

Вмешательства

• Процедура Cryoablation
  Patients undergo cryoablation.
• Препарат Serplulimab
  Patients undergo cryoablation. If there are no significant postoperative complications, Serplulimab should be administered immediately. Cycles with Serplulimab repeat every 3 weeks for up to 1 year in the absence of disease progression or unacceptable toxicity.
