My husband has been on Nexavar for the past three months and has absolutely NO side effects. When he was on IL-2, a clinical trial, and Sutent the side effects were almost completely debilitating (fatigue, sores,etc). We are going to find out next week if the Nexavar has shrunk his tumors or at least stabilized them. I was wondering if anyone out there has any experience with a chemo that caused no side effects yet still worked? It's worrying me that the drug is not working because he is back to his old self and has a ton of energy! Or has anyone experienced no chemo side effects and the drug didn't work either?
