phase 1 trial

— A research study designed to find out how a new drug is dealt with by the body, how the people given it react to it, and the lowest dose that may be effective

Full explanation:

Phase 1 trials are studies that usually involve small numbers of healthy people. They are designed to find out how the treatment works in the body and how the people treated react to it.

This type of study also aims to find out the lowest dose at which the treatment is effective, known as the minimum therapeutic dose, and the highest dose at which it can be taken without causing harm.
