Novel therapeutic with Fast Track and Orphan Designation

LONDON, UK / ACCESSWIRE / April 30, 2024 / Poolbeg Pharma (AIM:POLB)(OTCQB:POLBF), 'Poolbeg' or the 'Company'), a biopharmaceutical company focussed on the development and commercialisation of innovative medicines targeting diseases with a high unmet medical need, announces that it 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.

Key Highlights
12-month option agreement with Silk Road Therapeutics to acquire novel topical muco-adherent formulation of Pentoxifylline (tPTX), a treatment for oral ulcers in patient's suffering from Behçet's Disease which currently has no cure

Phase 2 trial successfully completed, demonstrating superiority over standard of care

Secured Orphan Drug Designation and Fast Track Designation from the FDA

Positioned for a potential 505(b)(2) approval pathway in the U.S.

Poolbeg will continue due diligence throughout the term of the exclusive option agreement which will include engagement with Silk Road Therapeutics to ascertain the clinical approval pathway

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.^[1] Patients also suffer from reduced psychosocial quality of life^[2]. 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."

Enquiries

About Behçet's Disease
Behçet's Disease is a rare condition that results in inflammation of the blood vessels and tissues. Inflammation across multiple parts of the body leads to diverse symptoms, the most prevalent being recurrent oral ulcers, in addition to genital ulcers and inflammation of the eye and skin lesions. It is not yet known what triggers the disease or causes it to persist. However, it is clear there is a significant immune component with some suggestions that exaggerated responses to pathogens and increased cytokine and chemokine production may play key roles in the disease.^[3]
