Anyone know what is expected by phase 2 trial of a drug?

What happens surrounded by a phase 2 trial?? I believe that it meand upgrading from ape to human trials but i'm not sure.
It means its more addictive and more dart.
may be death.
Once the initial safekeeping of the therapy have been confirmed within Phase I trials, Phase II trials are performed on larger groups (100-300) and are designed to assess clinical efficacy of the treatment; as well as to verbs Phase I assessments in a larger group of volunteers and patients. The nouns process for a new drug commonly fail during Phase II trials due to the discovery of poor efficacy or toxic effects.
Phase II studies are sometimes divided into Phase IIA and Phase IIB. Phase IIA is specifically designed to assess dosing requirements, whereas Phase IIB is specifically designed to study efficacy.
Some trials combine Phase I and Phase II into a single trial, monitoring both efficacy and toxicity.
I know pharmaceutical companies study different parameters within different phases. For instance, a phase 1 might be safety (side effects) and the cohort is relatively small and a phase 2 might be efficacy and long-term safekeeping with a larger group, while a phase 3 might be superiority over other drugs and an even larger group. There are probably more detailed guidelines for determining what might constitute a phase but what I purely wrote was a broad guideline.
Phase two is when you start testing your drugs on population with the specific weakness you intend to treat. Well, that is phase 2 clinical trials at most minuscule.
Phase 1 clinical is where you try-out it on college students to see what the side effects are. That;s where they achieve their lists of side-effects on commercials.
