First Patient Expected to be Enrolled by Q2 of 2022

Data To Support Regulatory Filings in the United States

Virpax^® Pharmaceuticals, Inc. (“Virpax” or the “Company”) (NASDAQ: VRPX), a company specializing in developing product candidates for pain management, CNS disorders and anti-viral indications, signed a clinical trial agreement with Altasciences Company, Inc., a leading clinical trial services company, for a First in Human study investigating Epoladerm™ for pain associated with osteoarthritis of the knee. The study will take place in Canada with a CTA filing and enrollment of the first patient anticipated by Q2 of 2022.

“Performing trials in Canada is an efficient and cost-effective way for Virpax to add robust data in support of the 505(b)(2) FDA approval pathway for Epoladerm™ . Through partners like Altasciences, we may strategically accelerate our optimized drug delivery therapeutic candidates through pre-clinical and clinical development,” commented Chairman & CEO Anthony P. Mack.

About Epoladerm™

Virpax Pharmaceuticals is developing Epoladerm™ (diclofenac epolamine), an investigational analgesic supplied in a pre-filled device for administration as a topical spray film to manage chronic pain associated with osteoarthritis of the knee. Our proprietary technology provides a convenient aerosol canister for application of the spray film to the knee. The resulting film is thinner than a standard liquid bandage, is visibly clear on the knee and is fast-drying. The spray formulation avoids the inconvenient and messy application of creams or gels to the knee.

About Virpax Pharmaceuticals

Virpax is developing branded product candidates for non-addictive pain management and neurological disorders using its proprietary technologies to optimize and target drug delivery. Virpax is initially seeking FDA approval of its three patented drug delivery platforms. Epoladerm™ is a topical diclofenac spray film formulation being developed to manage osteoarthritis pain. Probudur™ is a single injection long-acting liposomal bupivacaine formulation being developed to manage post-operative pain. Envelta™ is an intranasal Molecular-Envelope Technology (MET) enkephalin formulation being developed for the management of acute and chronic pain, including pain associated with cancer, as well as post-traumatic stress disorder (PTSD) under the name PES200. MET technology is also used in AnQlar™, a candidate to inhibit viral replication caused by influenza or SARS-CoV-2. Virpax recently acquired global rights to VRP324, a product candidate for the nasal delivery of a pharmaceutical-grade cannabidiol (CBD) for the management of epilepsy in children (a rare pediatric disease) and adults.
