Clywedog Therapeutics

What Clywedog Therapeutics does

Clywedog Therapeutics is a clinical-stage biopharmaceutical company headquartered at 8 The Green, Suite 8666, Dover, Delaware, developing first- and best-in-class small-molecule therapies for metabolic and autoimmune diseases. The company is advancing three differentiated, clinical-stage product candidates: Balomenib (CLY-101), an oral, reversible menin protein–protein interaction (PPI) inhibitor intended to restore pancreatic beta-cell function and promote insulin production in Type 1 and Type 2 diabetes; CLY-201, an oral small-molecule TYK2 inhibitor designed to block type I interferon and IL-12/23 signaling and protect beta-cells from autoimmune destruction in Type 1 diabetes; and VTP-1000, an antigen-specific tolerance immunotherapy for celiac disease built on the SNAP-Tolerance Immunotherapy platform, which would enter the portfolio through the pending Barinthus Biotherapeutics merger. Discovery is supported by a proprietary hybrid AI/ML drug discovery platform developed in conjunction with Expert Systems, integrating multi-target and multi-property optimization, predictive pharmacology, and biomarker strategies across chemical/biological modalities including oral protein degraders, molecular glues, protein-protein interaction inhibitors, covalent/reversible binders, and synthetic lethality dual inhibitors.

Clywedog is pre-revenue with no commercial products; its primary clinical asset Balomenib has entered a multicenter, international Phase 1b study in Type 2 diabetes with up to 60 participants dosed over a 28-day treatment period (centers activated December 2025). Pricing is undetermined and no commercial distribution channels exist today; the company's stated go-to-market posture is commercialization through specialty pharmaceutical channels upon regulatory approval, supplemented by clinical-trial-site operations for current development. The company has no disclosed product revenue and is funded by venture capital.

Clywedog was co-founded and seed-funded by OrbiMed Advisors and Torrey Pines Investment, with additional support from the Expert Systems hybrid AI/ML drug discovery accelerator. On September 30, 2025, the company entered a definitive all-stock merger agreement with Barinthus Biotherapeutics plc (NASDAQ: BRNS), expected to close in the first half of 2026, after which the combined company will be renamed Clywedog Therapeutics, Inc. and trade on NASDAQ under the ticker CLYD, with Barinthus shareholders owning approximately 34% and Clywedog stockholders approximately 66% on a fully diluted basis. Additional investment from TPAV, LLC is intended to extend the combined company's cash runway through 2027. Upon closing, OrbiMed venture partner Iain Dukes will transition from CEO of Clywedog to Executive Chairman of the combined company, and Barinthus Bio CEO Bill Enright will become CEO. The merger has attracted two law-firm investigations (Halper Sadeh LLC; Monteverde & Associates PC) regarding potential breaches of fiduciary duty and federal securities laws.

Functional benefit

Products and services

• Balomenib (CLY-101) A best-in-class, oral, reversible menin protein-protein interaction (PPI) inhibitor being developed for the treatment of Type 2 diabetes and Type 1 diabetes. By blocking menin interactions, it stimulates regeneration of pancreatic islets and improves de novo insulin production.
• CLY-201 (TYK2 Inhibitor) A first-in-class, oral, small-molecule TYK2 inhibitor with an outstanding safety and tolerability profile, in clinical development for T1D prevention and early treatment. It targets T-cell-mediated inflammation that destroys insulin-secreting pancreatic beta cells by mediating type I interferon and interleukin signaling.
• VTP-1000 A highly differentiated antigen-specific tolerance immunotherapy designed to prevent or reduce symptoms following gluten exposure in patients with celiac disease, utilizing the SNAP-Tolerance Immunotherapy (SNAP-TI) platform.

Quantifiable outcome

• Phase 1 completed with demonstrated safety and tolerability in healthy volunteers with PK/PD data supporting T1D and T2D potential
