I consider the question ill-posed because "age" isn't one thing - it's many different things, many of which are forms of accumulative damage that your body doesn't know how to repair, and there are already drugs that target or prevent things like oxidative damage, sun damage, or increase cell turnover, etc. I think there will be more types of damage that drugs can prevent or repair in future, but it'll be a while before taking them reliably increases healthy years by a noticeable degree.

@GrahamPoulter I suppose I'll call that a "no", since I don't believe the FDA would just use "age" as a condition (as opposed to say "age-related presbyopia")
