Regabatin: A New Solution Filling a Controlled Release Gap

Our once-a-day Regabatin™ (pregabalin) extended-release capsules are indicated for the management of neuropathic pain associated with diabetic peripheral neuropathy, postherpetic neuralgia, spinal cord injury and fibromyalgia. Regabatin™ is based on our controlled release drug delivery technology platform which utilizes the symptomatology and chronobiology of fibromyalgia in a formulation intended to provide a higher exposure of pregabalin during the first 12 hours of dosing. Based on positive feedback and guidance from the FDA, we submitted an IND application for Regabatin™ in August 2015. The FDA completed its review of the IND application and provided constructive input that we will use towards further development of the program.

The brand reference drug is Lyrica® (immediate release pregabalin). A controlled-release version of pregabalin should reduce the number of doses patients take, potentially improving patient compliance and clinical outcomes.

Phase I Clinical Trial

We successfully completed an initial Phase I clinical trial of a controlled-release pregabalin formulation. This was the first bioavailability study of our controlled-release pregabalin versus Lyrica® (immediate release pregabalin).

Phase I Clinical Trial Results

We conducted and analyzed the results of six Phase I clinical trials involving a twice-a-day formulation and a once-a-day formulation. For formulations directed to certain indications which include fibromyalgia, the results suggested that Regabatin™ 82.5 mg BID dosage was comparable in bioavailability to Lyrica® 50 mg (immediate-release pregabalin) TID dosage. For formulations directed to certain other indications which include neuropathic pain associated with diabetic peripheral neuropathy, the results suggested that Regabatin™ 165 mg once-a-day dosage was comparable in bioavailability to Lyrica® 75 mg BID dosage.
