Study Endpoints

Primary Endpoints

Efficacy of a Fixed Dose of Bremelanotide as Measured by FSFI (Question Q1 and Q2), 28-day Recall.
8 weeks baseline plus 24 weeks (Main Study), 52 Weeks (OLE)

As measured by change from baseline to end-of-study in the desire domain from the FSFI (Question Q1 and Q2), 28-day recall, co-primary endpoint - FSFI desire domain This score is on a scale ranging from 1.2 to 6. A higher score on this scale represent an increase in sexual desire and is a better outcome.

Efficacy of a Fixed Dose of Bremelanotide as Measured by FSDS-DAO (Item 13)
8 weeks baseline plus 24 weeks (Main Study), 52 Weeks (OLE)

As measured by the change from baseline to End-of-Study of the Core Study in the bothered by low desire item from the FSDS-DAO (item 13). Responses range from 0 (never) to 4 (always). Lower scores on this scale represent an increase in sexual desire and indicate a better outcome. Higher scores indicate a worse outcome.

Percent change in body weight between treatment arms
Change from the baseline (Visit 2/Day 1) to Visit 10 (Day 57)

Percent change in patient weight from baseline (Visit 2/Day 1) to Visit 10 (Day 57) for the BMT/tirzepatide combination group compared to placebo

To demonstrate the efficacy of 0.5 mg subcutaneous BMT (given twice a day), used in combination with a subject's maximum tolerated dose of RAAS inhibition therapy, reduces urinary protein by 50% from baseline UP/Cr levels.
Baseline to after six months of combined therapy (RAAS inhibition therapy plus BMT).

Proportion of subjects with Type II diabetic nephropathy who achieve a 50% reduction in their urine protein Cr (UP/Cr) ratio after six months of combined therapy (RAAS inhibition therapy plus BMT). Inhibition therapy to reduce urinary protein and maintain podocyte density and functions in subjects with Type II diabetic nephropathy after six months.

To determine the incidence of overall adverse events, related adverse events, a composite of adverse events of special interest, serious adverse events, and the incidence of BMT discontinuation.
Baseline to after six months of combined therapy (RAAS inhibition therapy plus BMT).

Proportion of subjects with Type II diabetic nephropathy who achieve a 50% reduction in their urine protein Cr (UP/Cr) ratio after six months of combined therapy (RAAS inhibition therapy plus BMT) to determine the incidence of adverse events, related adverse events, adverse events of special interest, serious adverse events and BMT discontinuation.

The Primary Efficacy Endpoint is Change From Baseline to End of Study in the Number of Satisfying Sexual Events (SSE)
4 - 12 weeks from baseline to end of study (total study duration 20 weeks). Baseline was the 4-week single-blind placebo period.

The primary efficacy endpoint is change from baseline to end of study in the number of satisfying sexual events (SSEs), computed as the number of events during the last 4 weeks of treatment with FSEP-R Q10 = "Yes" minus the number of baseline events with FSEP-R Q10 = "Yes." Efficacy analyses were done with the MITT population which consisted of all randomized subjects who took at least 1 dose of double-blind treatment after the 2 in-clinic doses of double-blind medication and who had at least 1 follow-up visit (Visit 10 or later) to ensure that FSEP-R data were reviewed and confirmed by the investigative site.

Secondary Endpoints

Efficacy of a Fixed Dose of Bremelanotide, as Measured by the Change in Baseline to End of Study (EOS) in the Number of Satisfying Sexual Events (SSEs) Associated With Study Drug Administration
8 weeks baseline plus 24 weeks (Main Study), 52 Weeks (OLE)
Efficacy of a Fixed Dose of Bremelanotide, as Measured by the Change in Baseline to End of Study in Mean Desire Score (Q3) From the FSEP-R

Frequently asked questions about Bremelanotide

What is Bremelanotide used for?

Bremelanotide is an investigational small molecule peptide being developed for hypoactive sexual desire disorder, female sexual arousal disorder, obesity, and kidney disease. It is in clinical trials for these conditions, including Phase 3 studies in premenopausal women with hypoactive sexual desire disorder.

What does Bremelanotide target?

Bremelanotide is a peptide that targets melanocortin receptors, which are involved in sexual desire and arousal. By activating these receptors, it aims to address the underlying mechanisms of hypoactive sexual desire disorder and female sexual arousal disorder.

Who makes Bremelanotide?

Bremelanotide is being developed by Palatin Technologies, Inc., a biopharmaceutical company traded on the NYSE American under the ticker symbol PTN. The company is conducting clinical trials to evaluate the drug's safety and efficacy across multiple indications.

What phase is Bremelanotide in?

Bremelanotide is in Phase 3 clinical development for hypoactive sexual desire disorder, with two completed Phase 3 trials. It is also being studied in Phase 2 trials for obesity and kidney disease. It remains investigational and has not been approved by regulatory authorities.

What clinical trials is Bremelanotide in?

Bremelanotide has been studied in several clinical trials, including NCT02333071 and NCT02338960, both Phase 3 trials in premenopausal women with hypoactive sexual desire disorder. It is also being evaluated in NCT05709444 for diabetic kidney disease and NCT06565611 for obesity in combination with tirzepatide.

Is Bremelanotide the same as Vyleesi?

Bremelanotide is also known by the brand name Vyleesi, which is a trade name for the drug. The clinical trials and development programs for Bremelanotide refer to the same active pharmaceutical ingredient marketed under this brand name.
