Can a drug be approved after Phase 2?
A confirmatory phase II trial, which need not be randomized if an active control is not available, can provide sufficient evidence to convince regulatory authorities to grant accelerated approval, and the process can be completed in three years or less.

What are the 3 phases of clinical trials?
- Phase I studies assess the safety of a drug or device. ...
- Phase II studies test the efficacy of a drug or device. ...
- Phase III studies involve randomized and blind testing in several hundred to several thousand patients.
What is a Phase 0 clinical trial?
Phase 0 studies use only a few small doses of a new drug in a few people . They might test whether the drug reaches the tumor, how the drug acts in the human body, and how cancer cells in the human body respond to the drug.
How long do drug trials usually take?
Clinical trials alone take six to seven years on average to complete. Before a potential treatment reaches the clinical trial stage, scientists research ideas in what is called the discovery phase. This step can take from three to six years.
