What is a clinical trial?

A clinical trial is a carefully designed research study that tests how well new medical approaches work in people. Clinical trials test whether new treatments are safe and effective. They are subject to various regulatory controls to ensure the safety of participants.

Phases of clinical trials

Medication and treatment clinical trials are divided into four phases. All new medications must be tested in phase 1, 2 and 3 trials before they can be approved for use by the general public.

Phase 1

After lab testing, the medication is tested on a small group of healthy volunteers or people with the disease/condition for the first time. Phase 1 trials assess safety, identify side effects and determine the effective safe dosage range for the medication. These trials are generally short (up to one year), highly controlled and participants are closely monitored.

Phase 3

Phase 3 trials compare the intervention medication to current standard of care or a placebo. These larger trials involve several thousand participants and generally run for several years. The purpose of Phase 3 trials is to confirm effectiveness, monitor side effects, and ensure safe use of the medication. Randomized, placebo-controlled, blinded trials ensure accurate results.

Phase 2

​After successfully completing Phase 1, the medication moves to Phase 2. During this phase, the medication is tested on several hundred participants with the disease/condition to determine its efficacy and further evaluate its safety. Participants continue to be closely monitored during Phase 2 trials. These trials can run for several months and up to 2 years.

Phase 4

After regulatory approval for use as a medication, the medication is monitored in the general population for long-term safety, benefits and risks. Phase 4 trials continue to monitor the efficacy and adverse effects of the medication associated with widespread use of the medication over longer periods of time. Phase 4 trials involve several thousands of participants.
