Further expansion of IP portfolio enhancing protection of Poolbeg’s growing pipeline
26 May 2022 – Poolbeg Pharma (AIM: POLB, OTCQB: POLBF, ‘Poolbeg’ or the ‘Company’), a clinical stage infectious disease pharmaceutical company with a unique capital light clinical model, has been granted patents by the US Patent and Trademark Office (USPTO) for POLB 001, a small molecule immunomodulator for the treatment of severe influenza and POLB 002, a first-in-class, intranasally administered RNA-based immunotherapy for respiratory virus infections.
The USPTO granted a patent for the majority of Poolbeg’s claims around the use of certain p38 MAP kinase (mitogen-activated protein kinase) inhibitors for the treatment or prevention of severe influenza and the hypercytokinaemia (or “cytokine storm”) it causes through modulation of the immune response (reducing the body’s hyperinflammatory response to the virus). To further strengthen its position, Poolbeg will pursue a continuation patent application to augment the protection offered by this patent family.
Poolbeg holds the worldwide rights to POLB 001 for all uses in humans and as such, is exploring the opportunity to expand its IP around this asset to cover new disease areas which would maximise the value of the asset for partnering purposes.
The USPTO granted a patent for the identification of defective interfering (DI) RNA-based influenza viruses for use against infection by influenza, that provides a drug candidate with both antiviral prophylactic and therapeutic applications. By having a dual mechanism of action POLB 002 (which was identified using this method) directly interferes with influenza virus replication blocking disease progression and also triggers nasal cells into an antiviral state . In this way, POLB 002 could provide pan-viral protection from respiratory virus infections including influenza, respiratory syncytial virus (RSV), SARS-CoV-2 and others.
The Company is continuing working with its patent advisors to broaden and expand the POLB 001 and POLB 002 patent families.
Jeremy Skillington, PhD, CEO of Poolbeg Pharma, said:
“The additional US patent protection of POLB 001 and POLB 002 is an important step in the commercialisation of these novel infectious disease products. Enhancing the IP protection of these assets across key markets such as the US increases the overall value of these products to potential partners, particularly as we move closer to the commencement of our POLB 001 LPS human challenge trial next month with data expected by year end and monetisation to commence thereafter.”

About Poolbeg Pharma
Poolbeg Pharma is a clinical stage infectious disease pharmaceutical company, with a capital light clinical model which aims to develop multiple products faster and more cost effectively than the conventional biotech model. The Company, headquartered in London, is led by a team with a track record of creation and delivery of shareholder value and aspires to become a “one-stop shop” for Big Pharma seeking mid-stage products to license or acquire.
The Company is targeting the growing infectious disease market. In the wake of the COVID-19 pandemic, infectious disease has become one of the fastest growing pharma markets and is expected to exceed $250bn by 2025.
With its initial assets from Open Orphan plc , an industry leading infectious disease and human challenge trials business, Poolbeg has access to knowledge, experience, and clinical data from over 20 years of human challenge trials. The Company is using these insights to acquire new assets as well as reposition clinical stage products, reducing spend and risk. Amongst its portfolio of exciting assets, Poolbeg has a small molecule immunomodulator for severe influenza (POLB 001); a first-in-class, intranasally administered RNA-based immunotherapy for respiratory virus infections (POLB 002); and a vaccine for Melioidosis (POLB 003). The Company is also developing an oral vaccine delivery platform and is progressing two artificial intelligence (AI) drug discovery programmes to accelerate the power of its human challenge model data and biobank.
