Trial phases (Phase 1, 2, 3)
The stages a new treatment must pass through before it can be approved for routine use.
What it is
A clinical trial is divided into several phases to test a new treatment's safety and effectiveness. Phase 1 focuses on a small group of people to see if the treatment is safe and can be tolerated. If it is, the treatment moves on to Phase 2, where it's tested in a larger group to see if it works and if it has any side effects.
How it works
In a clinical trial, participants receive the new treatment and are closely monitored by doctors and researchers. The researchers track the participants' responses to the treatment, including any side effects they may experience. The data collected from these trials helps researchers understand how the treatment works and if it's safe for use in a larger population.
Why it matters
Understanding the different phases of a clinical trial is important for patients and carers because it helps them understand the progress of a new treatment. It also gives them a better idea of what to expect if they're considering participating in a trial. By following the phases, researchers can ensure that new treatments are safe and effective before they're made available to the public.
