The first stage of clinical testing in humans, typically involving 20-100 healthy volunteers. Tests safety, dosage, and side effects. Most peptides in the research pipeline are at or before this stage.
"Phase I Trial" is filed under Evidence & Research in the PeptideAtlas glossary, alongside 14 other terms in that group.
A study where participants are randomly assigned to receive either the treatment or a control (placebo or standard care). The gold standard for establishing causality in medical research.
Clinical trials involving 100-300 patients with the target condition. Tests efficacy and further evaluates safety. Provides initial evidence of whether a peptide works for its intended purpose.
Large-scale clinical trials involving 1,000-3,000+ patients. Confirms efficacy, monitors adverse effects, and compares to existing treatments. Required for FDA drug approval.
