Recruiting nowPhase 2
What this trial is trying to do
The researchers are testing whether adding β-hydroxybutyrate, a ketone-body dietary supplement, to short-course radiotherapy followed by immunotherapy and CAPEOX chemotherapy can increase tumour eradication before surgery in locally advanced rectal cancer. The treatment sequence includes total mesorectal excision surgery.
The idea is that the added supplement might improve the chance of a complete response compared with the expected response to the treatment sequence without it. The trial measures complete response rate, rather than directly testing whether people live longer or avoid surgery.
Worth knowing: This is a small, non-randomised phase 2 study with no comparison group, so any difference cannot be separated reliably from other factors, and complete response is not the same as longer survival.
Written from the trial's own registry entry to explain what the researchers are testing and why. Nothing here is a result — this trial has not reported one — and it is not a view on whether the treatment works or on whether it would suit you.

What is being tested
- Radiotherapy Short-course radiotherapy
- Drug Capecitabine
- Drug Oxaliplatin
- Procedure TME surgery
- Supplement β-hydroxybutyrate
What it is measuring
complete response (CR) rate
This is the trial's main question — the one it is designed and sized to answer. Anything else it reports is a secondary finding, and secondary findings are far more likely to be chance.
Phase 2. Tests whether the treatment works well enough to be worth a larger trial. Usually too small to prove it changes survival.
How the researchers describe it
This study is a prospective phase II clinical trial aimed at exploring the potential benefits of supplementing β-hydroxybutyrate with existing short course radiotherapy sequential immunotherapy and CAPEOX therapy.

Where it is running
Running at 1 site. Listed in: China.
Individual hospitals, and whether each is currently open, are listed on the registry record. Sites open and close throughout a trial.
Worth asking your oncology team
Being listed here is not a recommendation, and no one page can tell you whether a trial is right for you. These are the questions it raises.
- Is this trial open at a hospital I could realistically travel to?
- Given my stage, my previous treatment and my tumour's molecular profile, would I be eligible?
- What would I be giving up by joining — is the comparison arm the treatment I would otherwise be having?
- What is already known about the safety of what is being tested?
