## Brief Summary

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.

## Detailed Description

The specific treatment process is shown in the trial flow diagram. The patients underwent WIRA whole-body hyperthermia on days 1 and 8 of each HIT cycle. On day 2 (24 h after hyperthermia on day 1), 200 mg of tislelizumab prepared with 100 mL of normal saline was intravenously administered for less than 30 min. After six HIT cycles, tislelizumab was administered intravenously every 21 days until drop-out. For quality control of hyperthermia, the core temperature was set to 38·5-39·5 °C and measured using a rectal temperature-sensing probe. Hyperthermia was considered to have been achieved when this temperature range was recached and maintained for 60 min. Each hyperthermia session lasted for 2 h, including a 30-min heating stage, a 60-min insulation stage, and a 30-min cooling stage. Clinical data were collected every two HIT treatment cycles and evaluated using the RECIST version 1.1 standard.

## Arms

- **hyperthermia combined with immune checkpoint inhibitor group** (EXPERIMENTAL) — 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).

## Interventions

- **Water-filtered infrared A radiation whole-body hyperthermia (HECKEL 3000MT-4T, Germany)** (DEVICE) — The patients were treated with whole-body hyperthermia (HECKEL 3000MT-4T, Germany)) on days 1 and 8 of each hyperthermia combined with immune checkpoint inhibitor treatment cycle along with administration of tislelizumab (BeiGene, China) 200 mg on day 2 (24 hours after the hyperthermia at day 1).
- **tislelizumab (BeiGene, China) combined with PD-1 inhibitor** (DRUG) — The patients were treated with whole-body hyperthermia (HECKEL 3000MT-4T, Germany)) on days 1 and 8 of each hyperthermia combined with immune checkpoint inhibitor treatment cycle along with administration of tislelizumab (BeiGene, China) 200 mg on day 2 (24 hours after the hyperthermia at day 1).

## Primary Outcomes

- **disease control rate (DCR)** _(time frame: up to 6 months)_ — DCR=(PR+CR) / (PD+SD+PR+CR) \* 100%

## Secondary Outcomes
