The Jamaica Plain Gazette interviews a man who has participated in 269 clinical trials to date.
Couldn't the effects of one drug or experimental treatment interfere with another one (even one that is done later rather than simultaneously)?
In theory, rooting out adverse drug interactions is desirable during clinical trials. In practice, they usually just leave that bit of data gathering up to the general population.
But, clinical trials usually don't like to use the elderly for other reasons. It's very hard to find healthy ones, which makes adverse effects harder to pin down, and if one happens to die during the clinical trial for an unrelated reason, you lose data and you have to explain that your drug wasn't responsible.
That said, given the rising ages of baby boomers, I imagine Phase IV trials involving the elderly are more common these days.
Yes it could, and astute researchers take that into consideration and manage their studies accordingly.
