Tislelizumab Plus Chemotherapy and BACE for Unresectable NSCLC

Официальное название

Tislelizumab Combined With Intravenous Chemotherapy and Bronchial Artery Chemoembolization as Conversion Therapy for Unresectable Non-Small Cell Lung Cancer: A Multicenter, Single-Arm, Phase II Trial (BEACON-Lung)

Обзор

The goal of this phase 2 trial is to evaluate the efficacy and safety of tislelizumab combined with intravenous chemotherapy and bronchial artery chemoembolization (BACE) as conversion therapy for patients with initially unresectable stage IIIA-IIIB non-small cell lung cancer (NSCLC). The main questions it aims to answer are: * What is the 1-year event-free survival (EFS) rate with this treatment? * Can this treatment improve tumor response and the chance of curative-intent resection? * What adverse events occur during treatment? Participants will receive tislelizumab, intravenous chemotherapy, and BACE for up to 4 cycles. Tumor response and resectability will be evaluated by imaging and multidisciplinary team (MDT) assessment every 2 cycles. Participants who become resectable may undergo surgery followed by postoperative treatment per protocol. Participants who remain unresectable after 4 cycles will receive guideline-recommended chemoradiotherapy followed by tislelizumab consolidation. Regular follow-up will be performed for efficacy and safety assessment.

Вмешательства

• Препарат Tislelizumab
  Tislelizumab 200 mg is administered intravenously on Day 0 of each 21-day cycle for up to 4 cycles. Postoperative or consolidation tislelizumab may be given according to protocol-defined treatment pathways.
• Препарат Intravenous Chemotherapy
  Intravenous chemotherapy is administered on Day 1 of each 21-day cycle for up to 4 cycles. Patients with lung squamous cell carcinoma receive albumin-bound paclitaxel, and patients with lung adenocarcinoma receive pemetrexed. Carboplatin is administered intra-arterially during BACE in cycles with the procedure; if BACE is not performed in a given cycle, carboplatin is administered intravenously on the same day per protocol.
• Процедура Bronchial Artery Chemoembolization (BACE)
  BACE is performed on Day 1 of the first 21-day treatment cycle using intra-arterial carboplatin infusion followed by embolization with 300-500 μm blank microspheres. Subsequent BACE procedures are performed on demand, based on tumor response on contrast-enhanced chest CT and multidisciplinary team (MDT) evaluation. The total number of BACE procedures ranges from 1 to 4.
