Phase II APEC trial: The impact of primary tumor side on outcomes of first-line cetuximab plus FOLFOX or FOLFIRI in patients with RAS wild-type metastatic colorectal cancer.

ABSTRACT:

Aim

The open-label, nonrandomized, phase II APEC study enrolled 167 patients with RAS wild-type (wt) metastatic colorectal cancer (mCRC) to investigate the safety and efficacy of first-line, every-2-weeks cetuximab plus investigator's choice of FOLFIRI or FOLFOX in this patient population.

Methods

A subgroup analysis of the APEC study population by primary tumor location was performed.

Results

A total of 130 patients (81.8%) had left-sided and 29 (18.2%) had right-sided mCRC. Median progression-free survival (PFS), overall survival (OS) and overall response rate (ORR) were 14.0 months, 30.6 months and 68.5% for patients with left-sided tumors and 8.9 months, 24.6 months and 51.7% for patients with right-sided mCRC, concurring with pivotal phase III trial results.
