andrew von eschenbaugh and cnn's david crowell, and cnn's very own elizabeth cohen, author of "the empowerednt." good evening to all of you. david kroll, start you first. when we hear cases like jake collier's, it seems like to make a lot of sense, give his father at least the option to ask for a drug in the late stages of the testing. that could help save his son's life. is that worth it? >> i think we have to step back and realize that the reason that we have a drug approval process is so that we get drugs to people who need them as quickly as possible while also having a good measure of the relative safety of the drug in the particular setting where it's going to be used. so we do take into account that when we're developing these kinds of drugs that people are in sort of terminal life-threatening situations. and so a lot of times we really don't know until the drug gets almost all the way up to approval just how effective it's going to be. >> you don't think he should get that option until he gets almost up until approval? >> well, i mean, so phase one trials don't even tell you anything
