First-in-Class Therapies for Gastrointestinal Disease and Metabolic Disorders
The Bilayer Approach
Our novel therapeutic approach and innovative delivery system aim to bring long-lasting benefits to the tens of millions of people who suffer from gastrointestinal conditions and metabolic disorders. Bile acids function as unique modulators of metabolism and motility, and delivery with our proprietary bilayer technology can unlock their full therapeutic potential.
Patients deserve better options. That is why we developed the Bilayer approach.
Bilayer Therapeutics is a development-stage company 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 metabolism and motility. With a naturally occurring bile acid (chenodeoxycholate or CDC) delivered via proprietary bilayer tablet technology, the company is developing innovative first-in-class treatments for a range of metabolic and motility disorders.
Metabolic syndrome comprises several indications, including obesity, Type 2 diabetes, stroke and heart disease. Bilayer Therapeutics is using CDC to increase glucagon-like peptide 1 (GLP-1), the key hormone whose receptor is targeted by multiple approved drugs and other incretins such as peptide YY, to treat these conditions and to provide them in an easy-to-take oral format. CDC also activates both established mechanisms of action for treating motility disorders (fluid influx and peristalsis of the colon).
By using CDC, Bilayer Therapeutics aims to offer more effective treatments that will cause fewer side effects for patients.
Produced from cholesterol in the liver and stored in the gallbladder, chenodeoxycholic functions as a unique modulator of human metabolism and motility. And while this bile acid has been approved for use as a therapeutic agent in the upper gastrointestinal tract, its use in the lower GI tract—where many metabolic and motility disorders occur—has not been fully explored.
Since most bile acids are reabsorbed in the small intestine, immediate-release treatments are ineffective and cause unwanted side effects when used in the lower GI tract. That’s why we teamed up with experts at 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, to develop our proprietary bilayer tablet delivery system.
Rather than relying on single-layer, high-dose rapid-release drugs, Bilayer tablets feature a dual mode of action: A thinner immediate release layer and a thicker, extended-release therapeutic layer. This approach targets the TGR5 receptor on L-cells in the colon (especially in the distal parts) and is the first to activate the body’s natural functions of fluid flow and motility, which are critical in treating metabolic and gastrointestinal disorders.
With the ability to use bile acids in the lower GI tract for the first time, we have built a pipeline with investigational treatments for metabolic and motility disorders, hepatic encephalopathy, ulcerative colitis and Crohn’s disease.
Mechanism of action:
- First-in-class treatment for a range of disorders mediated by the colon
- Naturally occurring bile acid formulation with oral delivery and the potential for a benign side effect profile, proven in humans
- Biphasic slow-release delivery system with unique pharmacokinetic profile for treatment of the entire colon, including distal regions close to the rectum
- Dual mode of action for sustained delivery
- Polymethacrylate-based coating for targeting the cecum, the early part of the colon
Bilayer is led by a team of world-renowned academic, medical and industry professionals with deep drug development, drug delivery and gastrointestinal expertise.
