Trial Phases

Though silicosis has no known cure at this time, clinical trials may be conducted to test new drugs and procedures to fight this disease. A clinical trial consists of three phases

Phase I trials usually work with a small number of people to test how new drugs or procedures can best be given.

Phase II trials give early information about how a new drug or procedure works, what benefits it might give, and how safe it is for patients.

Phase III trials test new drugs or procedures against current standard treatments. This phase usually involves many people from across the nation who receive either the new treatment or the standard treatment.
