General question about statistical analysis

I'm wondering how accurate a statistical analysis is if the test isn't replicated? For example, in a drug study where a group of participants is split in two, half given a placebo and half given the actual drug, and the results tabulated, etc., and then reported in medical journals. If the study is never replicated, how reliable are the results? (leaving out, for the moment, that it was the drug company sponsoring the study, which doesn't make me feel better, but so it goes).

I hope you can answer what seems to be a ridiculously simple question. (sorry) Thank you for your time.
