Most recent registered trials

How to read this. These are counts of studies registered on ClinicalTrials.gov, the US clinical trial registry. Registration is not evidence of benefit, and a registered trial may never report results. Counts are the most complete public measure of research activity, not a verdict on whether a compound works.

Frequently asked questions

Are there clinical trials for Thymosin alpha-1?

Thymosin alpha-1 has 67 registered clinical trials, including 23 completed interventional studies and trials reaching Phase 4. Its use in humans is supported by established registered clinical evidence.

Does a registered trial mean the peptide works?

No. Registration means a study was formally listed before or during the research. It says nothing about the result. A completed trial can find no benefit, and many registered studies are never published.

What is the difference between a registered trial and published evidence?

Registration records that a study exists. Publication reports what it found. This page counts registrations, which is the more complete picture of research activity, but it is not a measure of proven effectiveness.

Why do phases matter?

Phase 1 tests safety in a small group. Phase 2 looks for early signs of effect. Phase 3 tests effectiveness against a comparator in a large group, and is what regulators normally require. Phase 4 studies happen after approval. A compound with only Phase 1 trials has not been shown to work.
