Clinical Trial

Research

Clinical Trial — A research study conducted in human subjects to evaluate the safety and efficacy of a compound, the final stage before regulatory approval of peptide therapeutics.

What Is a Clinical Trial?

A clinical trial evaluates safety, efficacy, and optimal dosing of a drug candidate in human volunteers. For peptide therapeutics, clinical trials follow Phase I-IV progression as the final drug discovery pipeline stage.

Phases

Phase I: 20-100 healthy volunteers. Safety, PK, maximum tolerated dose
Phase II: 100-300 patients. Efficacy, optimal dose in target disease
Phase III: 1,000-5,000 patients. Large-scale confirmation for regulatory approval
Phase IV: Post-market surveillance

Notable Peptide Programs

Elamipretide (Phase III, Barth syndrome), tesamorelin (FDA-approved, HIV lipodystrophy), oral semaglutide (FDA-approved, demonstrating commercial-scale oral peptide delivery).

Frequently Asked Questions

What is Clinical Trial?
