Neoadjuvant Radiotherapy for Rectal Adenocarcinoma With Capecitabine Versus TAS-102 (Neo-REACT): A Multi-center, Randomized, Phase III Trial
Neoadjuvant fluoropyrimidine-based chemoradiotherapy followed by total mesorectal excision (TME) is the standard of care for locally advanced rectal cancer (LARC); however, pathologic complete response (pCR) rates are low. Trifluridine/tipiracil (TAS-102) is a new oral anti-tumor oral formulation of nucleoside analogue, trifluridine (FTD), and a thymidine phosphorylase inhibitor, tipiracil (TPI). Previous studies have shown that TAS-102 has shown clinically relevant activity after fluoropyrimidine failure in colorectal cancer and may thus be of increased efficacy compared with current standard capecitabine chemoradiation. Also, a phase 2 trials conducted by our team have demonstrated that neoaduvant TAS-102 concurrent with long-course radiotherapy could lead to a high pCR rate of 32% with acceptable toxicity for LARC patients. Herein, we will conduct this multicenter, randomized controlled, phase III trial to explore the safety and efficacy benefit of TAS-102 concurrent with long-course radiotherapy for LARC.

Interventions
- TAS-102
- Capecitabine
Primary outcomes
- Complete response (CR) rate — 1 year
The primary outcomes is CR rate, which is the sum of the number of patients with a pCR who undergo surgery plus the number of patients with a cCR who undergo watch-and-wait divided by the total number of evaluable patients.
