Official title
A Single-Arm, Single-Center Study of Exploring the β-hydroxybutyrate Supplementation and Short-Course Radiotherapy Followed by Immunotherapy Combined With CAPEOX Neoadjuvant Therapy in Locally Advanced Rectal Cancer
Overview
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.
Interventions
- Radiation Short-course radiotherapy
Eligible subjects will receive short-course radiotherapy (SCRT). One week after the end of treatment, subjects continued to receive neoadjuvant chemotherapy. - Drug Capecitabine
1000mg/m2, bid, po, d1-14,q3w - Drug Oxaliplatin
130mg/m2, ivgtt, d1,q3w - Procedure TME surgery
The surgery was performed 1 week after the end of neoadjuvant therapy. - Dietary supplement β-hydroxybutyrate
Oral β-hydroxybutyrate supplement (5g/day, starting from the day of first radiotherapy, lasting for 2 weeks).
Primary outcome measures
- complete response (CR) rate [Time frame: an expected average of 12 months]
Secondary outcome measures (3)
- 3-year disease-Free Survival [Time frame: an expected average of 3 years]
- Overall Survival [Time frame: an expected average of 5 years]
- Adverse events (AEs) were graded according to the NCI CTCAE version 5·0 [Time frame: an expected average of 1.5 years]

Exclusion criteria
- Patients with non-pMMR LARC;
- Subjects who have previously received any form of immunotherapy, including but not limited to immune checkpoint inhibitors, immune checkpoint agonists, immune cell therapy, or any other treatment targeting tumor immunomodulatory mechanisms;
- Presence of any concurrent disease, condition (including laboratory abnormality), history of substance abuse, or current evidence thereof, which, in the judgment of the Investigator, may compromise subject safety, interfere with the process of obtaining informed consent, affect subject compliance, or confound the safety assessment of the investigational product(s).
