LONDON, UK: Poolbeg Pharma (AIM: POLB) has entered into an exclusive 12-month option agreement with Silk Road Therapeutics Inc,  for a nominal fee, to acquire a novel topical muco-adherent formulation of Pentoxifylline (tPTX) for the treatment of oral ulcers in patient’s suffering from Behçet’s Disease.

There is a clear unmet medical need for an effective treatment for this rare disease, which has no cure. Behçet’s Disease causes inflammation of blood vessels and tissues, resulting in debilitating symptoms, the most common being oral ulcers which impact essential functions like eating, drinking and speaking.

Patients also suffer from reduced psychosocial quality of life. Current standard of care is inadequate with safety concerns and there is a clear need for alternative treatment options.

The topical formulation of PTX, a small molecule with broad anti-inflammatory activity, has successfully demonstrated accelerated oral ulcer healing and decreased pain compared to standard of care in patients with Behçet’s Disease in a Phase 2 clinical trial.

The drug is positioned for a potential 505(b)(2) approval pathway in the U.S. which can result in a much less expensive and much faster route to approval and commercialisation. tPTX has successfully secured FDA Fast Track Designation, designed to expedite development and review of certain medicines. It has also received Orphan Drug Designation from the FDA, providing seven years of market exclusivity upon marketing authorisation.

Jeremy Skillington, PhD, Chief Executive Officer of Poolbeg Pharma, said: “The foundation of any pharma company is a strong pipeline of assets, and we believe that topical PTX could fit well into our pipeline alongside our other assets as we increase our focus on rare and orphan diseases.

“We are delighted to enter this exclusive option agreement with Silk Road Therapeutics and Dr Timothy Coté, whose extensive experience, including as Director of the FDA Office of Orphan Products Development, adds invaluable insights into the regulatory pathway and ultimate approval and commercialisation of the drug.

“tPTX has the potential to transform the lives of patients suffering from Behçet’s Disease, who currently lack effective and safe long term treatment options. Under this exclusive option agreement, we will advance our due diligence process and engage with Silk Road Therapeutics to further understand the clinical pathway to approval, and we look forward to updating the market in due course.”

Timothy R. Coté, M.D., M.P.H., Chief Executive Officer of Silk Road Therapeutics, said: “Poolbeg Pharma shares our commitment to advancing healthcare innovation to support rare disease patients. With Fast Track Designation and Orphan Drug Designation secured, topical PTX has the potential to swiftly reach patients and offer a potentially transformative solution for those suffering from Behçet’s Disease.”
