Abstract

Purpose: Trifluridine/tipiracil (FTD/TPI; TAS-102, Lonsurf®), a novel form of chemotherapy for metastatic colorectal cancer (mCRC), has shown clinical benefit in the global, phase III RECOURSE trial, regardless of patient age. Here, we report the safety and tolerability profile of FTD/TPI from an expanded-access program (EAP) in the US patients with mCRC whose disease has progressed on the standard therapies. Methods: A total of 549 patients (≥ 18 years) with histologically confirmed mCRC following two or more regimens of standard therapy and an Eastern Cooperative Oncology Group performance status of 0 or 1 participated in this open-label EAP. During the 28-day treatment cycle, patients took FTD/TPI 35 mg/m2 twice daily for 5 days followed by 2 days of rest for 2 weeks, with a 14-day rest period. Data were collected for therapy duration, treatment discontinuation, and adverse events. Age-based post hoc analysis was performed to determine the safety of FTD/TPI in elderly (≥ 65 years) versus younger (< 65 years) patients. Results: FTD/TPI-treated patients in this EAP had a similar therapy duration and time to treatment discontinuation to those in the RECOURSE trial. The safety profile in elderly patients was consistent with that in younger patients, with no unexpected safety concerns. Conclusions: This USA-based, open-label EAP has confirmed a similar safety and tolerability profile for FTD/TPI to that observed in the RECOURSE trial. Furthermore, FTD/TPI is well tolerated and can be considered as a treatment option in elderly patients with mCRC. Trial registration: NCT02286492.
