Phase 3 clinical trials are larger trials typically conducted with up to several thousand participants and are designed to establish if the intervention is safe and effective in preparation for product approval. The results show whether or not the intervention is beneficial to a particular group of participants.

Phase 2 clinical trials are conducted with up to several hundred participants. They are designed to collect additional information about whether the intervention is safe and effective. The results of these types of clinical trials may be used to design future trials or to develop additional research methods.

Phase 1 clinical trials are small-scale clinical trials with very few participants to examine the way the intervention (e.g., medication) interacts with the human body. The purpose of the study is to collect information about the safety of the interventions assessed. These trials are typically conducted in healthy participants without a specific medical condition.
