BACKGROUND: Fluoropyrimidines + angiogenesis inhibitor or dose-reduced doublets are used for (frail) elderly patients with metastatic colorectal cancer (mCRC). This non-comparative trial evaluated two 1st line regimens for patients not eligible for full-dose combinations.
METHODS: This open-label, multicenter, phase II study randomized untreated mCRC patients ≥ 70 years ± frailty 1:1 to dose reduced mFOLFOX7 in Arm A or aflibercept (4 mg/kg) plus dose reduced mLV5FU2 in Arm B. Primary endpoint was the 6-months PFS rate (PFS@6), secondary endpoints included safety, overall survival (OS), overall response rate (ORR), patient reported outcomes and overall treatment utility (OTU).
FINDINGS: The full analysis population comprised 120 patients (62 Arm A, 58 Arm B; 63% male), with a median age of 78.5 years. 82% frail patients were included. PFS@6 was 68% [95%CI 56%;80%] in Arm A and 46% [32%;59%] in Arm B. Median PFS was 7.9 and 5.5 months, median OS was 20.4 and 19.0 months and ORR was 47% and 22% in Arm A and B, respectively. At 3 months, 52% in Arm A and 35% in Arm B had a good OTU. Most frequent grade ≥ 3 AEs in Arm B were hypertension (41%) and proteinuria (10%). More patients in arm B had treatment-related SAEs grade ≥ 3 (17% in arm B and 5% in arm A).
INTERPRETATION: Both regimens were feasible in this (frail) elderly population. Dose-reduced mFOLFOX7 and, to a lesser extent, 5-FU/aflibercept showed good PFS and 3-month OTU. Although most patients were regarded frail, survival rates were promising, most likely due to effective further-line treatments.
