Water-filtered Infrared A Radiation Whole-body Hyperthermia Combined With Immune Checkpoint Inhibitor Therapy for Advanced Gastrointestinal Tumours: A Prospective Open-label Single-arm Phase 2 Study

ZhejiangH

Gastrointestinal tumours (GITs) are the most common and fatal cancers worldwide; 96% of GITs show the microsatellite-stable (MSS)/proficient mismatch repair (pMMR) phenotype, and these tumours have a poor response to immune checkpoint inhibitor (ICI) therapy. Hyperthermia combined with ICI treatment (HIT) has been reported to show a synergistic sensitisation effect in numerous basic studies. This study aimed to validate the effectiveness, safety, and feasibility of water-filtered infrared A radiation (WIRA) whole-body hyperthermia combined with PD-1 inhibitor therapy and evaluate the real-world clinical application prospects of HIT. This open-label single-arm phase 2 clinical trial aimed to enrol advanced GIT patients with the MSS/pMMR phenotype in the East Asian population who had received third-line or higher treatment. The patients were treated with whole-body hyperthermia on days 1 and 8 of each HIT cycle along with administration of tislelizumab 200 mg on day 2 (24 h after the hyperthermia at day 1). The primary outcome was the disease control rate (DCR), while the secondary outcomes were progression-free survival (PFS), overall survival (OS), safety, and improvement in quality of life.
