Hi, my husband has advanced RCC and just started Torisel. He is on his fourth infusion. It's a chemotherapy targeted drug that inhibits the growth of metastatic kidney cancer. There's not much info out there beyond the clinical trials - when I went to the official site I couldn't understand all the jargon. Out of the three standard treatments for RCC (besides IL-2) Torisel is the most promising treatment, according to our oncologist. The chances for allergic reaction are high, but they can usually get around it with a cocktail of premeds. At the moment we use a combo of demerol, pepcid, hydrocortisone, and benedryl and infuse the Torisel over an hour instead of the standard half hour. We are waiting to see a response, but the doctor said it would take at least 6 infusions. As far as other side effects there is always the nausea, vomiting, and fatigue - Zofran is a pretty good antiemetic to combat these symptoms.
I hope I was helpful.
