FIRST-IN-CLASS TREATMENT FOR CONSTIPATION AND OTHER COLONIC DISORDERS

CHRONIC CONSTIPATION: UNMET NEED

More than 42 million Americans suffer from chronic constipation, and today’s treatments are failing to clear up symptoms for many patients and causing debilitating side effects for others. People deserve better options. That is why we developed the Bilayer approach.

About Us

Bilayer Therapeutics is a development-stage company co-founded in 2020 by a team of world-renowned drug development and delivery experts and gastroenterologists to stimulate the body’s innate mechanisms for regulating constipation and diarrhea. With a naturally occurring bile acid (chenodeoxycholate or CDC) delivered via proprietary bilayer tablet technology, the company is developing innovative treatments for Chronic Constipation, Inflammatory Bowel Disease and other diseases of the colon.

CDC activates both established mechanisms of action for treating constipation: fluid flow and motility in the colon. By using CDC, Bilayer Therapeutics aims to offer more effective treatments for chronic constipation and other diseases of the colon, a challenging and under-exploited organ, that will cause fewer side effects for patients.

Technology

Bilayer’s lead program, BL-010, is a potential first-in-class therapeutic for chronic constipation co-developed by the Langer and Traverso Labs at the Massachusetts Institute of Technology and Dr. Joshua Korzenik, gastroenterologist and Director of the Crohn’s and Colitis Center at Brigham and Women’s Hospital.

BL-010 consists of chenodeoxycholate (CDC), a naturally occurring primary bile acid that has been approved by the FDA for the dissolution of gallstones in an instant release formulation since 1983. When delivered to the colon, BL-010 develops a biphasic, extended-release profile and mimics the way the body regulates the equilibrium between constipation, normal state and diarrhea. Initial research conducted by the Mayo Clinic demonstrated CDC’s potential to treat patients with Irritable Bowel Syndrome with Constipation.

Where current treatment options rely on single-layer, rapid-release drugs, BL-010 features a dual mode of action: A thinner immediate release layer and a thicker, extended-release therapeutic layer. This approach is the first to activate both fluid flow and motility in the colon, and is expected to allow BL-010 to be dissolved evenly without abdominal discomfort.

Bilayer’s proprietary bilayer tablet technology has other potential applications for the treatment of colonic and metabolic disorders including diabetes and obesity, and plans to pursue these other indications once proof of concept has been established.
