Flamel Technologies has reached agreement with FDA for a special protocol assessment for the design and planned analysis of a Phase 3 clinical trial of FT218, a once nightly formulation of sodium oxybate that uses the company’s proprietary drug delivery platform, Micropump. The Phase 3 trial, entitled “A Double-blind, Randomized, Placebo Controlled, Two Arm Multi-center Study to Assess the Efficacy and Safety of a Once Nightly Formulation of Sodium Oxybate for Extended-Release Oral Suspension (FT218) for the Treatment of Excessive Daytime Sleepiness and Cataplexy in Subjects with Narcolepsy,” recently commenced patient enrollment in Canada, with sites in Europe and the U.S. to be initiated near-term.

“We believe our once nightly formulation of sodium oxybate has the potential to offer significant improvements over the current standard of care, in addition to meaningful improvement in overall quality of life for patients suffering from narcolepsy,” the company says. Sodium oxybate is the sodium salt of gamma hydroxybutyrate, an endogenous compound and metabolite of the neurotransmitter gamma-aminobutyric acid (GABA), which is approved in the U.S. as a twice nightly formulation indicated for treating of cataplexy and excessive daytime sleepiness in patients with narcolepsy at doses up to 9g/night.

Flamel says the Micropump is a microparticulate system that allows the development of modified and/or controlled release of solid, oral dosage form drugs. It achieves “extremely precise pharmacokinetic profiles of single or combination of drugs, in a variety of formats (such as tablets, capsules, sachet, or liquids (LiquiTime®), while preserving the targeted release rate over the shelf-life of the product,” it says.
