I will answer a bit tongue in cheek: Why not? Why not give experimental drugs to dying patients? Doctors give experimental drugs to ill patients who agree to such simply because they don't have health coverage. They agree because they have no other way of having some kind of follow-up in their illness. This is what happened to my mom. She had breathing problems, signed up for some sort of experimental drug, and two years later died. Was it worthwhile? Can I even ask the question "did she have the right to use experiemental drugs?" Oh yeah, SHE wasn't a terminally ill patient at the time.
The question itself is misleading. I mean, how can we say yes when such experimental drugs can be dangerous? Oh yeah, that's right. The patients are dying anyway; They're gonna die anyway. Might as well make it worth our while. But where is the humanity in such reasoning? We are not talking about the patients' right to use such drugs. We are actually asking if it is morally permissible for US (not just the doctors but also us, the future patient) to ask them to take them.
My mom (Cassondra Draper) made her decision because she thought she had no other choice. I don't know if all of her subsequent health problems were side effects or not, but I found the medical community of Albuquerque, New Mexico rather callous of her condition when I found her bed ridden in her own home, unable to walk, front door unlocked so that the mailman could come in and hand her her mail. She was 55 when she died. I sure hope it was all worthwhile.
