Immunomodulator I Patent Portfolio Strengthened

Notice of allowance for patent grant in Japan

20 September 2023 - Poolbeg Pharma (AIM: POLB, OTCQB: POLBF, 'Poolbeg' or the 'Company'), a clinical-stage biopharmaceutical company targeting diseases with a high unmet medical need, announces that it has received a notice of allowance from the Japanese Patent Office in relation to its Immunomodulator I patent application.

The claims deemed allowable cover a p38 MAPK (mitogen-activated protein kinase) inhibitor for use in the treatment of severe influenza in human patients and strengthens the Company's robust intellectual property in the territory. Grant of the application as a patent is expected upon completion of formalities.

Poolbeg has a worldwide licence for POLB 001 for all uses in humans and is developing a strong IP portfolio with patents in place, including Immunomodulator I and Immunomodulator II, covering the use of the class of p38 MAP kinase (mitogen-activated protein kinase) inhibitors for the treatment of severe influenza and hypercytokinaemia. The Company has also filed patent applications to expand its IP around POLB 001 and the use of p38 MAP kinase inhibitors in new disease areas, such as oncology. This enhances the value and attractiveness of POLB 001 to potential pharma partners.

Jeremy Skillington, PhD, Chief Executive Officer of Poolbeg Pharma, commented: "This milestone is a testament to the uniqueness of p38 MAPK inhibition as a potential blockbuster treatment for severe influenza. We are committed to continuing to strengthen the intellectual property protection of our portfolio of assets into new jurisdictions to increase their overall value to potential partners."
