Trofinetide, sold under the brand name Daybue, is a medication used for the treatment of Rett syndrome. [3] It is taken by mouth. [3]

Contents

The most common adverse reactions include diarrhea and vomiting. [4]

Trofinetide was approved for medical use in the United States in March 2023. [3] [4] [5] [6] The US Food and Drug Administration (FDA) considers it to be a first-in-class medication. [7]

Medical uses

Trofinetide is indicated for the treatment of Rett syndrome in people two years of age and older. [3] [8]

Rett syndrome is a rare, genetic neurological and developmental disorder that affects the way the brain develops. [4] People with Rett syndrome experience a progressive loss of motor skills and language. [4] Most babies with Rett syndrome seem to develop as expected for the first six months of life. [4] These babies then lose skills they previously had attained at approximately six to 18 months of age — such as the ability to crawl, walk, communicate, or use their hands. [4] The hallmark of Rett syndrome is near constant repetitive hand movements, such as rubbing or clapping. [4] Rett syndrome leads to severe impairments affecting nearly every aspect of life, including the ability to speak, walk, eat, and breathe. [4]

History

It was developed by Neuren Pharmaceuticals that acts as an analogue of the neuropeptide (1-3) IGF-1, which is a simple tripeptide with sequence Gly-Pro-Glu obtained by enzymatic cleavage of the growth factor IGF-1 within the brain. Trofinetide has anti-inflammatory properties and was originally developed as a potential treatment for stroke, [9] [10] but has subsequently been developed for other applications and is approved by the FDA as an oral solution. It has successfully completed phase III clinical trial against Rett syndrome. [11] Trofinetide has also had a successful phase II trial against Fragile X syndrome. [12] [13] [14] The drug is manufactured by Acadia Pharmaceuticals.[ citation needed ]

The US Food and Drug Administration (FDA) evaluated the efficacy and safety of trofinetide based on a randomized, double-blind, placebo-controlled, 12-week study (Study 1; NCT04181723) of participants with Rett syndrome five to 20 years of age. [4] Participants were randomized to receive trofinetide (N=93) or matching placebo (N=94) for 12 weeks. [4] The dose of trofinetide was based on participant weight to achieve similar exposure in all participants. [4]

The FDA granted the application for trofinetide priority review, orphan drug, and fast track designations. [4]
