Is it safe to participate in clinical trials?

Yes, all clinical trials have risks. But any medical test, treatment, or procedure has risks. The risk may be higher in a clinical trial because there are more unknowns. This is especially true of phase I and II clinical trials, where the treatment has been studied in fewer people.

Why clinical trials take so long?

The clinical trial process is long – and it’s set up that way so that by the time drugs reach the public, they have been thoroughly evaluated. But the length of the process is one reason why it’s so important for volunteers to take part. Without enough volunteers, up to 80% of clinical trials are delayed.

How many types of clinical trials are there?
