TAS-102 Plus Radiotherapy in Elderly ESCC

This study is a single-arm, multicenter clinical trial evaluating the efficacy and safety of radiotherapy combined with TAS-102 monotherapy in elderly patients with locally advanced esophageal cancer. Treatment Phase: The treatment phase is divided into a Phase I stage and a Phase II stage. The Phase I stage aims to explore the maximum tolerated dose (MTD) of TAS-102 in elderly esophageal cancer patients. A total of 9 subjects were enrolled, and the dose was escalated from 30 mg/m² in 5 mg/m² increments up to 40 mg/m². The MTD was defined as the highest drug dose at which no dose-limiting toxicity (DLT) was observed in more than 40% of treated patients during the first two weeks of combined radiotherapy and TAS-102 administration. The Phase II stage aims to investigate the efficacy of radiotherapy combined with TAS-102 at the MTD in elderly esophageal cancer patients, with 36 subjects enrolled. Consolidation Phase: Following the treatment phase, subjects had a 3-4 week rest period. This was followed by consolidation therapy with TAS-102 monotherapy at a dose of 35 mg/m², administered twice daily on days 1-5 of a 28-day cycle for two cycles. Subsequently, patients entered the efficacy and safety follow-up phase until the study endpoints were reached or after a full 2-year follow-up period.

Low-dose Trifluridine/Tipiracil With Bevacizumab in mCRC

This is a phase II, single-center, prospective trial aimed to investigate the efficacy and safety of a modified regimen of trifluridine/tipiracil plus bevacizumab in refractory metastatic colorectal cancer. Patients will be treated with trifluridine/tipiracil (17.5 mg/m2 dose orally twice daily, d1-10, every 14-days) plus bevacizumab (5mg/kg dose intravenously once at day 1, every 14-days). The study treatment will be administered until progression of disease, intolerable toxicity or withdraw of consent.
