MAZD

Mazdutide

A synthetic acylated peptide based on the sequence of oxyntomodulin, a naturally occurring product of the proglucagon gene that acts at two receptors. It is an agonist at the glucagon receptor and the GLP-1 receptor.

Mazdutide has 12 registered human studies on ClinicalTrials.gov, reaching phase 4, covering 3,143 planned or enrolled participants across the 12 studies that published a figure. No FDA-approved product contains Mazdutide. 45 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 Mazdutide; the registry search is fuzzy, so every match is re-checked. None of this says whether Mazdutide works or is safe.

36 loose registry matches were checked and 12 confirmed — 24 named something else and were discarded. We count a study only when Mazdutide 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.

What Mazdutide is, and what it has been studied for

Mazdutide is classified by ChEMBL as a protein, and appears in trial registrations under IBI-362 and IBI362. Its FDA substance identifier is MB76Z4IBZ5.

Across 12 registered trials, it has been studied in Obesity, Type 2 Diabetes, Overweight and Obesity and Type 2 Diabetes Mellitus (T2DM). 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 Eli Lilly and Company and Shanghai Zhongshan Hospital 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.

Mazdutide reached Phase 4 across 12 registered trials.

No FDA-approved product contains Mazdutide. A compound can stop at any rung for commercial reasons as easily as scientific ones, and the registry does not record which.

45 papers and 12 registered trials between 2017 and 2026. A paper counts when “Mazdutide” 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.
