Once a treatment idea is developed, it has to Ao through a few phases before reaching the general public. Each phase is asking a different question: Is it safe? Does it work? How does it compare to what's already out there? It's difficult to answer all of those at once, so trials build the picture in stages. S こがおれなん CLINICAL TRIALS 101'.

This phase tests whether a treatment is actually safe- like, does the body tolerate it- rather than whether the treatment works.

You need hundreds or thousands of people because you're trying to catch things that only show up rarely; a side effect that happens in 1 in 2,000 people won't show up in a trial of 60.

Twenty people in one trial, thousands in another, different phases, the same drug and the same disease... It's all pretty confusing!

You may have heard of "phase 1, phase 2, phase 3" when it comes to #clinicaltrials, and each phase is simply answering a completely different question about the treatment.

By the time a treatment's approved, it's been through years of these separate, narrower questions, each one needing its own scale of trial to answer properly. Understanding what each phase is actually checking for hopefully makes that whole process a little less confusing.

Swipe through for the breakdown.
