Palatin Announces Publication of Vyleesi® (bremelanotide) fMRI Study in Women with Hypoactive Sexual Desire Disorder (HSDD)

Rhea-AI Summary

Palatin Technologies (NYSE: PTN) announced the publication of a study showcasing the effects of bremelanotide (Vyleesi) on sexual desire in women with hypoactive sexual desire disorder (HSDD). The double-blinded, placebo-controlled trial demonstrated that bremelanotide significantly increased sexual desire for up to 24 hours post-administration (P ≤ 0.01). This research correlates imaging data with increased sexual desire and enhances understanding of Vyleesi's mechanism of action. The study was funded by AMAG Pharmaceuticals and UK health institutions and is registered under NCT04179734.

Positive

• Bremelanotide significantly increased sexual desire for up to 24 hours post-administration.
• Study results were statistically significant, demonstrating potential for enhancing sexual brain processing in women with HSDD.
• First trial studying effects of melanocortin 4 receptor agonism on sexual brain processing in this demographic.

Negative

• None.

Peer-reviewed paper presents notable mechanism of action findings

Bremelanotide significantly increased sexual desire for up to 24 hours post administration

CRANBURY, NJ, Oct. 17, 2022 /PRNewswire/ -- Palatin Technologies, Inc. (NYSE American: PTN), a biopharmaceutical company developing first-in-class medicines based on molecules that modulate the activity of the melanocortin receptor system, today announced the publication of a third-party clinical study with bremelanotide (Vyleesi) in the Journal of Clinical Investigation entitled "Melanocortin 4 receptor agonism enhances sexual brain processing in women with hypoactive sexual desire disorder," by Thurston, et al. (Reference: J Clin Invest. 2022;132(19):e152341. https://doi.org/10.1172/JCI152341). Vyleesi is the first and only as-needed treatment approved by the U.S. Food and Drug Administration (FDA) for premenopausal women with HSDD.

The important findings in the double-blinded, placebo controlled, crossover study showed that bremelanotide enhanced sexual brain processing, including a significant increase in sexual desire for up to 24 hours after administration compared with placebo (statistically significant P ≤ 0.01). Increased satiety (appetite fullness feeling) and decreased food intake with bremelanotide treatment was also noted. Although other studies have been conducted showing the difference in sexual brain function between women with HSDD and non-HSDD women, this is the first trial to study the effects of melanocortin 4 receptor agonism with bremelanotide on sexual brain processing in women with HSDD.

"This extremely well-done clinical trial helps define Vyleesi's positive effects on sexual brain function and the relationship to increases in sexual desire in women with HSDD," stated Carl Spana, Ph.D., President and CEO of Palatin. "The study correlates imaging data with increased sexual desire for up to 24 hours post Vyleesi administration as reported by the participants. We are extremely excited and appreciative for this important data which demonstrates the beneficial impact of HSDD on the sexual brain and helps explain Vyleesi's mechanism of action in increasing sexual desire in women with HSDD."

The trial registration can be found at ClinicalTrials.gov under NCT04179734. This was an investigator-sponsored study funded by AMAG Pharmaceuticals Inc. (previous Vyleesi collaboration partner) and the Medical Research Council and National Institute for Health Research of the United Kingdom.
