-- Company Continues to Successfully Advance Product Candidates --

Virpax^® Pharmaceuticals, Inc. (“Virpax” or the “Company”) (NASDAQ: VRPX), today announced its financial results for the quarter ended March 31, 2022, and other recent developments.

“We continue to make excellent progress with all of our drug product candidates,” stated Anthony P. Mack, Chairman and Chief Executive Officer of Virpax. “In the first quarter of 2022, we secured global rights for AnQlar™, completed initial preclinical studies for VRP324, which is being developed to manage seizures associated with epilepsy in children, and announced the entry into a new CRADA with the U.S. Army for Probudor™.

“For substantially all of our product candidates, we have identified a distinct regulatory pathway (NCE, 505(b)(2), or OTC) based on FDA pre-IND guidance. Our robust pipeline provides U.S. commercial opportunities as well as ex-U.S. business opportunities. We intend to pursue global sublicensing and co-development opportunities with strategic biopharmaceutical partners as part of our non-dilutive funding strategy. Additionally, we will continue to pursue non-dilutive government and military grant agreements similar to our recently announced CRADA with the U.S. Army and our ongoing CRADA for the development of Envelta^™ with the National Institutes of Health’s National Center for Advancing Translational Sciences, which was awarded in 2020.

“We believe that our cash position, as well as our development and regulatory strategies, may allow Virpax to advance each product candidate efficiently and cost-effectively towards an anticipated clinical trial. As an example, we expect that data from our Molecular Envelope Technology (MET) preclinical studies may be able to be used to support the development of two drug candidates. Since Envelta and VRP324 both use our MET powder formulation, we may be able to reference the same MET preclinical data for both submissions, saving us time and money.

“As mentioned in a previous announcement, assuming the Envelta IND enabling studies and Phase 1 ‘first-in-human’ studies are accepted by the FDA for an acute/chronic pain indication, the parent IND and Phase 1 data is expected to be used to cross reference to the proposed PTSD indication, eliminating the need to repeat both the preclinical and Phase I work for a second indication,” continued Mr. Mack.

“While we have now secured global rights to all of our product candidates, our intention is to commercialize any products that we are able to get approved by the FDA in the U.S. and secure licensees for the rest of the world. Additionally, for our anti-viral product candidate, AnQlar, we intend to license or partner with another company that has OTC experience as we focus strictly on branded products. This licensing strategy along with our continued active pursuit of grants is non-dilutive and may extend our cash runway,” concluded Mr. Mack.

RECENT DEVELOPMENTS

• On May 5, 2022, Virpax announced a CRADA with the U.S. Army Institute of Surgical Research (USAISR), the U.S. Department of Defense’s (DOD) primary laboratory for developing solutions for trauma and critical care challenges in combat casualties, to evaluate Probudur. Probudur is being developed by Virpax to significantly reduce or eliminate the need for opioids after surgery in approved indications. In preclinical trials, Probudur has shown long duration pain control for at least 96 hours.
• On April 26, 2022, Virpax reported the successful completion of initial preclinical studies for VRP324, its nasal product candidate to manage seizures associated with epilepsy in children and adults. In this preclinical PK study using nasal administration in a rodent model, VRP324 was able to deliver high concentrations of cannabidiol (CBD) to the brain and confirmed that there were higher levels of CBD in the brain versus the plasma. Virpax believes that VRP324 may achieve higher efficiency via the nasal route compared to the oral CBD product currently on the market and may have negligible liver first-pass metabolism, thereby avoiding drug to drug interactions and potentially producing fewer side effects.
• On March 22, 2022, Virpax reported that all FDA required preclinical studies for Epoladerm^TM have been completed. Virpax is drafting FDA IND submission documents for Epoladerm that will include these preclinical studies.
• On March 15, 2022, Virpax announced that it expanded its exclusive agreement with Nanomerics Ltd. for AnQlar, its anti-viral product candidate, to include worldwide rights (an expansion from North American rights only).

FINANCIAL RESULTS FOR THE THREE MONTHS ENDED MARCH 31, 2022, AND 2021

Operating Expenses

General and administrative expenses were approximately $1.8 million for the first quarter of 2022, an increase of about $0.5 million from the first quarter of 2021. The increase was due to legal expenses, compensation related to new hires, insurance costs and non-executive board compensation. These expenses were partially offset by a decrease in stock-based compensation.

Research and development expenses were approximately $3.3 million for the first quarter of 2022 compared to approximately $1.1 million for the first quarter of 2021. The increase in research and development expenses was primarily attributable to milestone payments related to AnQlar, an increase in preclinical activities for AnQlar, Epoladerm and Probudur, and to a lesser degree, an increase in regulatory activities for Envelta and preclinical activities related to VRP324.

The operating loss for the first quarter of 2022 was approximately $5.1 million, as compared to $2.3 million for the first quarter of 2021.

Cash Flows

Operating Activities

Cash used in operations was approximately $6.0 million for the three months ended March 31, 2022, compared to $3.1 million for the three months ended March 31, 2021. The increase in cash used in operations was primarily the result of the increase in net loss and an increase in prepaid insurance and prepaid research and development costs.

Financing Activities

Cash provided by financing activities was approximately $15.3 million during the three months ended March 31, 2021, attributable primarily to net proceeds received from our initial public offering in February 2021 of $15.8 million, after deducting underwriting discounts and offering expenses. This was slightly offset by repayment in full of certain promissory notes in the amount of approximately $0.5 million in February 2021. No financing activities took place during the three months ended March 31, 2022.

At March 31, 2022, the Company had cash and cash equivalents of approximately $30.8 million.
