Absolutely. Ask if there are any specifics about the trial you need to know. As in if the trial doesn't work, is there a wait time to try another treatment (assuming one is available) My friend unfortunately had this come up when she was battling peritoneal cancer. Her trial chemo was combined with taxol. There was another chemo available to her after the taxol and trial chemo (though her chances at this point were slim) but because they had to wait until the trial was out of her system, and that was a three week wait followed by an uneccesary 2 weeks because she changed hospitals, and they put her off because the dr. was away on vacation and the unit was on slow down. That made it 5 weeks, and by that time she was so sick and had lost so much weight that they refused to treat her and moved her into palliative.

hugs and best of luck.
