First of all new drug is tested with a dose of Maximal tolerated dose (MTD) or a dose a bit lower than the MTD. Clinical trials that are subject to these requirements include trials conducted on both drugs and devices. CLINICAL. Clinical trials are conducted in a series of four steps or phases. POST. Trials in this phase can last for several years.

Clinical trials are conducted in a series of steps called “phases.” Each phase has a different purpose and helps researchers answer different questions. During the early phases (phases 1 and 2), researchers figure out whether a new treatment is safe, what its side effects are, and the best dose of the new treatment.
