A Phase I/II Study of Regorafenib Plus Avelumab in Solid Tumors
A Phase I/II Study of Regorafenib Plus Avelumab in Solid Tumors
Assessment of the efficacy and safety of Regorafenib and Avelumab in patients with advanced or metastatic solid tumors (ten cohorts), once the Recommanded Phase II Dose (RP2D) has been determined (phase I trial).
Assessement of the efficacy and safety of a low-dose of regorafenib (80mg/day) with avelumab in patients with advanced or metastatic colorectal tumors.
This is a multicenter, prospective open-labeled phase Ib trial based on a dose escalation study design (3+3 traditional design) assessing three dose levels of Regorafenib given in combination with Avelumab (no dose escalation for Avelumab) in patients with advanced digestive solid tumors followed by independent phase II trials to evaluate the association of Regorafenib at the RP2D with Avelumab in 17cohorts of advanced or metastatic tumors :
In addition, to evaluate in a phase II trial, the association of a low-dose of regorafenib (80mg/day) with avelumab :
