|Official title||OPTIMOX-aflibercept as First-line Therapy in 49 Patients With Unresectable Metastatic Colorectal Cancer. A GERCOR Feasibility Single-arm Phase II Study.|
|Principal investigator||Benoist Chibaudel, MD|
|Description||The addition of aflibercept to the standard FOLFIRI regimen as second-line therapy was evaluated in a large phase III study (EFC10262-VELOUR). This new combination significantly improved both PFS (4.7 to 6.9 months, HR=0.76; P=.00007) and OS (12.1 to 13.5 months, HR=0.82; P=.0032). In the evaluable population (86.5%), the tumor response rate was also improved when adding aflibercept (ORR=19.8% [16.4-23.2]) to the FOLFIRI regimen (ORR=11.1% [8.5-13.8]). This trial will evaluate the feasibility of adding aflibercept to an oxaliplatin-based regimen as a first-line therapy , using the OPTIMOX strategy rather than a continuous administration of chemotherapy until progression, in order to decrease the risk of severe toxicities.|
