Tesamorelin

A synthetic analogue of human growth-hormone-releasing hormone, residues 1 to 44, carrying a trans-3-hexenoyl group on the N-terminal tyrosine. That modification is what slows enzymatic degradation of the N-terminus. It binds the GHRH receptor on the anterior pituitary.

Tesamorelin has 18 registered human studies on ClinicalTrials.gov, reaching phase 4, covering 951 planned or enrolled participants across the 16 studies that published a figure. An FDA-approved product contains TesamorelinEGRIFTA (BLA022505). 46 papers naming it were published in the last ten years.

Collected 2026-08-02 from ClinicalTrials.gov and Drugs@FDA. Counts include only trials whose registered intervention names Tesamorelin; the registry search is fuzzy, so every match is re-checked. None of this says whether Tesamorelin works or is safe.

24 loose registry matches were checked and 18 confirmed — 6 named something else and were discarded. We count a study only when Tesamorelin is named as an intervention in it.

Registered means registered — not that the study finished, and not that it found anything. The grade is mechanical: it is computed from the registry and the FDA record alone, and it grades how much is known, never whether a compound is good or safe. Collected 2026-08-02 from ClinicalTrials.gov and Drugs@FDA. Check the query.

What Tesamorelin is, and what it has been studied for

Tesamorelin is classified by ChEMBL as a protein, and appears in trial registrations under TH-9507 and TH9507. Its FDA substance identifier is MQG94M5EEO.

Across 18 registered trials, it has been studied in HIV, Abdominal Obesity, Mild Cognitive Impairment and Lipodystrophy. A condition here is what a sponsor registered the trial under — it records what was investigated, not what was shown.

The trials were run by Massachusetts General Hospital and Theratechnologies among others. A named commercial sponsor means a compound is in formal development; its absence does not mean the opposite, only that no company has registered a trial under its own name.

An FDA-approved product contains Tesamorelin. Approval covers a specific product for a specific use — it is not a verdict on the molecule.

46 papers and 7 registered trials between 2017 and 2026. A paper counts when “Tesamorelin” appears in its title or abstract — phrase-matched, so a paper mentioning the words separately is not counted. The total is a single query over the whole window, which is why it does not equal the bars added together: PubMed files a paper under both its electronic and its print publication date, so one paper can appear in two years. Publication volume measures scientific attention, not whether a compound works: a well-studied compound can be well-studied and ineffective. Sources: PubMed and ClinicalTrials.gov · collected 2026-08-02.
