I was in one of the trials for getting lamogitrine approved for bipolar disorder. I'm female and that mattered only that I had a pregnancy test at the beginning of the trial. It was an interesting experience. I very obviously did not get the real drug so that part was a failure but I felt good about doing the study, I got to see extremely good doctors at a time I really needed them and ultimately I was on the real stuff and it helped a bit. So I'm glad I did it, even thought it ultimatley wasn't the drug for me.
