752Background: Elderly patients (≥65 yrs) with metastatic colorectal cancer (mCRC) are more likely to have comorbid conditions than younger patients ( < 65 yrs), limiting their therapeutic options. As previously reported (Mayer et al. J Clin Oncol 2017;35:abs 3559), FTD/TPI confirmed its clinical profile in mCRC in a real-world setting. Here, we report the safety and tolerability profile of FTD/TPI from the expanded-access program (EAP) in patients aged ≥65 yrs. Methods: Patients (≥18 yrs) with mCRC following ≥2 regimens of anticancer therapy and an Eastern Cooperative Oncology Group performance status of 0 or 1 were enrolled to this open-label EAP. Patients received FTD/TPI 35 mg/m2 twice daily for 5 days followed by 2 days’ rest for 2 weeks, with a 14-day rest period (28-day treatment cycle). Data were collected for therapy duration, treatment discontinuation, and adverse events (AEs). Results: Of 549 patients, 377 (68.7%) were aged < 65 and 172 (31.3%) were ≥65. The treatment duration of FTD/TPI was si...
