Purpose: Duligotuzumab is a dual-action antibody directed against EGFR and HER3. Experimental Design: Metastatic colorectal cancer (mCRC) patients with KRAS ex2 wild-type received duligotuzumab or cetuximab and FOLFIRI until progression or intolerable toxicity. Mandatory tumor samples underwent mutation and biomarker analysis. Efficacy analysis was conducted in patients with RAS exon 2/3 wild-type tumors. Results: Of 134 randomly assigned patients, 98 had RAS ex2/3 wild-type. Duligotuzumab provided no progression-free survival (PUS) or overall survival (OS) benefit compared with cetuximab, although there was a trend for a lower objective response rate (ORR) in the duligotuzumab arm. No relationship was seen between HS or ORR and ERBB3, NRC1, or AREC expression. it were fewer skin rash events for duligotuzumab but more diarrhea. Although the incidence of grade >= 3 AEs was similar, the frequency of serious ALs was higher for duligotuzumab. Conclusions: Duligotuzumab plus FOLFIRI did not appear to improve the outcomes in patients with RAS exon 2/3 wild-type mCRC compared with cetuximab + FOLHRI. (C) 2018 AACR.
