Frequently Asked Questions — Phase 3 Trials

Why are Phase 3 trials the standard for drug approval?
Phase 3 trials compare a new treatment against the current standard of care in a large, randomized population of 300–3,000+ participants. This large-scale comparative evidence is what regulatory agencies—FDA, EMA—require to approve a new drug. A successful Phase 3 trial demonstrates that the new treatment is more effective, safer, or both compared to existing options in a statistically significant, reproducible way.
What is a placebo control in a Phase 3 trial?
Many Phase 3 trials use a placebo control—a group that receives an inactive substance—to isolate the true effect of the treatment. When an established standard of care exists, control-arm participants typically receive that treatment rather than a placebo, for ethical reasons. Blinded designs prevent participants and investigators from knowing who received which treatment, reducing bias in outcome assessment.
How do I find and join a Phase 3 clinical trial?
ClinicalMetric lists all Phase 3 trials registered on ClinicalTrials.gov. Each trial card shows recruitment status, enrollment target, sponsor, conditions studied, and site locations. To join a Phase 3 trial, review the eligibility criteria and contact the trial site directly—usually an academic medical center or hospital. Your physician can facilitate a referral to the appropriate study site.
