Efficacy of Ginseng for Patients on Regorafenib

This is a randomized, multi-center phase II study of ginseng in colorectal cancer patients treated with regorafenib to determine if ginseng will reduce fatigue in this patient population and improve adherence to regorafenib. Ninety (90) subjects will be enrolled and randomized using a 2:1 allocation, with 60 subjects enrolled in the regorafenib + ginseng group and 30 enrolled in the regorafenib + no ginseng group.
