Background: Trifluridine/tipiracil (FTD/TPI) is a standard of care therapy for patients with refractory metastatic colorectal cancer (mCRC). Recently, FTD/TPI in combination with bevacizumab (BEV) was also approved in this setting based on outcomes from the phase 3 SUNLIGHT trial, including statistically significant improvements in overall survival (OS) compared with FTD/TPI. This study examined demographic/clinical characteristics, treatment duration, OS, and healthcare resource use (HCRU), including outpatient/emergency room (ER) visits and hospitalizations, among patients with mCRC receiving FTD/TPI+BEV versus FTD/TPI in a real-world setting. Methods: This was a retrospective study of adults with CRC, who initiated FTD/TPI as monotherapy or in combination with BEV, identified from the Cerner Enviza electronic health records (EHR) database (12/2020–06/2023). A manual chart review of patients’ medical records was conducted where last follow-up was defined as death or last encounter in the EHR. Descriptive statistics were reported for all study variables; Kaplan Meier curves were used to estimate OS. Results: Of 197 patients abstracted, 122 (62%) received FTD/TPI+BEV combination therapy and 75 (38%) FTD/TPI monotherapy. Mean age was similar between the FTD/TPI+BEV and FTD/TPI groups (60.2 y vs 61.8 y) and 66% vs 63%, respectively, were male. Mean Charlson Comorbidity Index was 8.9 for the FTD/TPI+BEV group vs 8.5 for the FTD/TPI group and body mass index was 26.9 kg/m2 vs 27.3 kg/m2, respectively. Most patients received treatment in the third or fourth line (65% FTD/TPI+BEV; 75% FTD/TPI). Median follow-up was 5.3 and 4.6 mo, respectively. Mean duration of treatment was 3.7 vs 2.7 mo for FTD/TPI+BEV vs FTD/TPI monotherapy (Table). Median OS (from FTD/TPI initiation to death) was 11.5 and 9.6 mo for FTD/TPI+BEV and FTD/TPI groups (number of deaths: 38 and 22), respectively. Patients receiving FTD/TPI+BEV had numerically more outpatient visits (20.5 vs 13.9), but similar ER visits (0.5 each) and slightly fewer hospitalizations (1.1 vs 1.2) compared with FTD/TPI, during follow-up. Overall HCRU costs were similar between groups (27,175 vs 27,891). Conclusions: This real-world study supports the value of FTD/TPI+BEV combination therapy vs FTD/TPI monotherapy as seen in the SUNLIGHT trial. Patients with FTDTPI+BEV were treated for longer duration with improved OS and no difference in trends for HCRU and associated costs.
