Brenipatide

updated

Brenipatide is Lilly’s investigational LY3537031, a 39-amino-acid dual GIP and GLP-1 receptor agonist. ClinicalTrials.gov listed 18 code-linked records; none had posted results.

Dual GIP and GLP-1 receptor agonist peptide

  • Modified 39-amino-acid peptide
  • Also indexed as LY3537031
  • Studied mainly by subcutaneous injection
  • No posted results in the cited trial records

What is brenipatide, and why do some records say LY3537031?

Brenipatide is the international nonproprietary name for Lilly's LY3537031. WHO describes it as a modified 39-amino-acid agonist at both the GIP and GLP-1 receptors. ClinicalTrials.gov records under either name belong to the same development program.

Five earlier ClinicalTrials.gov records use LY3537031 without the brenipatide name. Thirteen newer records are indexed under brenipatide and also include the code.

WHO INN · identity and receptor class

WHO nomenclature document

ClinicalTrials.gov records

ClinicalTrials.gov listed 18 unique NCT records under LY3537031 and a 13-record subset under brenipatide. Phase counts were 6 phase 1, 8 phase 2, and 4 phase 3. Three were completed, two active not recruiting, eleven recruiting, and two not yet recruiting. None had posted results.

  • Counts represent unique NCT identifiers across both aliases.
  • Five records use only the development code, so the brenipatide name covers 13 of 18 records.

Is brenipatide an approved medicine?

The cited FDA records list no approval or prescribing label for brenipatide or LY3537031. It remains an investigational drug used in registered studies.

A WHO name, a ClinicalTrials.gov entry, and a phase 3 designation describe development status. They do not authorize a drug for sale.

What does the current trial registry actually show?

The cited ClinicalTrials.gov records list 18 studies under the exact LY3537031 intervention name: 6 phase 1, 8 phase 2, and 4 phase 3. Three were completed, two were active but not recruiting, eleven were recruiting, and two were not yet recruiting. None of the 18 cited trial records included posted results.

Why does one drug appear in so many unrelated programs?

The registered program tests separate hypotheses in obesity, substance-use disorders, psychiatric disorders, asthma, chronic obstructive pulmonary disease, and irritable bowel syndrome. Results in one population cannot answer whether the drug works in another.

Program areaRegistered studies
Phase 1 and pharmacologyHealthy volunteers; overweight or obesity; hepatic impairment; renal impairment; absorption and bioavailability

Do the three completed phase 1 studies establish a safety profile?

The three completed records cover an early healthy-participant study, a renal-impairment pharmacokinetic study, and an absorption study. None posts adverse-event results, exposure tables, or a general contraindication list.

Completed is an administrative study status. Without posted results, it does not show how often adverse events occurred, whether any serious event was related to treatment, or which dose was tolerated.

Has brenipatide shown weight loss in people?

Two phase 1 records include participants with overweight or obesity, but neither provides a public brenipatide-specific weight-loss result. Registry status and enrollment alone cannot supply an efficacy estimate.

The current obesity study is active but not recruiting, has an estimated enrollment of 150, and has no posted results. It cannot support a percentage weight-loss claim or comparison with another drug.

Does dual GIP and GLP-1 receptor agonism predict the clinical result?

Dual GIP and GLP-1 receptor activity identifies the drug's intended targets. It does not predict the size or direction of its effects in obesity, addiction, psychiatric, respiratory, or gastrointestinal trials.

Results from another dual agonist cannot be copied to brenipatide. Sequence, exposure, receptor activity, dose schedule, population, and endpoint all matter.

Why is Brenipatide in C tier?

C tier recognizes a defined molecule and 18 registered human studies. None of those records had posted results, so efficacy, adverse-event rates, contraindications, interactions, and routine dosing remain unknown.
