Liraglutide

An analogue of human glucagon-like peptide-1 in which the lysine at position 34 is replaced by arginine and a C16 palmitic acid chain is attached through a glutamic acid spacer at lysine 26. It binds the GLP-1 receptor. The fatty-acid chain binds serum albumin, which is what slows its clearance relative to native GLP-1 — the same design principle as semaglutide, with a shorter chain.

Liraglutide has 442 registered human studies on ClinicalTrials.gov, reaching phase 4, covering 88,495 planned or enrolled participants across the 402 studies that published a figure. An FDA-approved product contains LiraglutideVICTOZA (NDA022341). 4,155 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 Liraglutide; the registry search is fuzzy, so every match is re-checked. None of this says whether Liraglutide works or is safe.

513 loose registry matches were checked and 442 confirmed — 71 named something else and were discarded. We count a study only when Liraglutide 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 Liraglutide is, and what it has been studied for

Liraglutide is classified by ChEMBL as a protein, and appears in trial registrations under NN-2211 and NN2211. Its FDA substance identifier is 839I73S42A.

Across 442 registered trials, it has been studied in Diabetes Mellitus, Type 2, Obesity, Type 2 Diabetes Mellitus and Healthy. 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 Novo Nordisk A/S and University at Buffalo 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 Liraglutide. Approval covers a specific product for a specific use — it is not a verdict on the molecule.

4,155 papers and 150 registered trials between 2017 and 2026. A paper counts when “Liraglutide” 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.
