Not really my area, but I think survival analysis comes into play here. Losing subjects may be (is?) a form of censoring. Art's point of getting enough subjects up front is valid. You also have to ask why you lost contact with the ones that did not complete the trial. If they're randomly wandering off, that's one thing. If the disease (or the treatment) is killing them, that's something entirely different.
