Clinical Trial 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.
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.
