--Company Advances Product Candidate Pipeline—

--Announces Preliminary Results from Virology Study--

Virpax^® Pharmaceuticals, Inc. (“Virpax” or the “Company”) (NASDAQ:VRPX), a company specializing in developing non-addictive product candidates for pain management, post-traumatic stress disorder, central nervous system (CNS) disorders and viral barrier indications, today announced its financial results for the quarter ended June 30, 2022, and other recent developments.

“We continue to advance our product candidate pipeline focused on pain, CNS and viral barrier indications,” stated Anthony P. Mack, Chairman and CEO of Virpax. “AnQlar’s preclinical studies continue to progress; we believe one of our preclinical virology studies shows an appropriate level of virus deactivation for a prophylactic viral barrier product candidate. We have a number of studies ongoing and expect to be reporting some results later this year.

“As we have previously stated, we are engaging in activities to potentially extend our cash runway as we move our product candidates forward. As part of this effort, we are evaluating grant opportunities and applying to those where we believe we have a reasonable chance of being selected. We recently announced and entered into a cooperative research and development agreement (CRADA) with the U.S. Army Institute of Surgical Research (USAISR) to evaluate Probudur^™, our wound site injectable product candidate that has demonstrated at least 96 hours of pain control in pre-clinical trials. The USAISR is the U.S. Department of Defense’s (DOD) primary laboratory for developing solutions for trauma and critical care challenges in combat injuries and casualties,” continued Mr. Mack.

“We engaged Prequient Inc., a consulting firm with extensive experience in the Consumer Self-Care or over-the-counter (OTC) marketplace. The Prequient team has been instrumental in analyzing the consumer proposition and assessing alternative regulator pathways such as our switch to an OTC pathway for Epoladerm^™, and the recently announced OTC medical device pathway for AnQlar. We believe being able to obtain potential approval for an OTC product or device should be less expensive and provide us with a faster drug development timeline and faster global approval track than the Rx prescription pathway that we originally were pursuing.

“Our expertise is in the prescription drug market, and we plan to develop our Rx product candidates and commercialize them in the U.S. However, we intend to license our OTC product candidates to a company that specializes in the Consumer Self-Care market. We believe combining the potential revenue from licensing these OTC product candidates to third parties with the potential licensing of our prescription product candidates outside the U.S., may allow us to offset a portion of our R&D expenses as we continue to grow,” concluded Mr. Mack.

RECENT DEVELOPMENTS

• On April 26, 2022, Virpax announced the successful completion of its initial preclinical studies for VRP324, the Company’s nasal product candidate to manage seizures associated with epilepsy in children and adults. Results from this PK study demonstrated high concentrations of CBD in the brain and confirmed higher levels of CBD in the brain versus the plasma.
• On May 5, 2022, Virpax announced that it has entered into a cooperative research and development agreement (CRADA) with the U.S. Army Institute of Surgical Research (USAISR) to evaluate Virpax’s Probudur™, an injectable long-acting liposomal bupivacaine in a hydrogel formulation that is injected at the wound site. Probudur is being developed to significantly reduce or eliminate the need for opioids after surgery. In pre-clinical trials, Probudur has shown pain control for at least 96 hours.
• On June 27^th, Virpax announced that it will pursue a direct to OTC regulatory pathway for Epoladerm™, the Company’s product candidate to treat pain associated with osteoarthritis. The direct to OTC, non-prescription regulatory pathway is expected to provide a faster drug development timeline and faster global approval track than the prescription pathway the Company had originally pursued for Epoladerm.
• Subsequent to the end of the quarter, on July 5, 2022, Virpax announced that it will pursue an OTC Intranasal Medical Device Consumer regulatory pathway for AnQlar™, the Company’s product candidate being developed as a prophylactic antiviral barrier against influenza and SARS-CoV-2. The Company believes that the OTC non-prescription Medical Device pathway is more efficient than the OTC non-prescription New Drug Application pathway that was originally pursued for AnQlar.
• The Company engaged Prequient Inc., a strategic consultancy firm experienced in developing products from concept through FDA approval and launch in the Consumer Self-Care marketplace. The principals in the firm have brought numerous products to the OTC marketplace including Flonase, Claritin, Tylenol and Panadol.

FINANCIAL RESULTS FOR THE THREE ENDED JUNE 30, 2022 AND 2021

Three Months Ended June 30, 2022 and 2021

Operating Expenses

General and administrative expenses were approximately $2.7 million for the second quarter of 2022, an increase of about $0.7 million from the prior year’s second quarter. The increase was due to legal defense costs with regard to litigation, compensation related to new hires and merit raises, insurance costs, non-executive board compensation and investor relations. These expenses were partially offset by a decrease in stock-based compensation.

Research and development expenses were approximately $3.3 million in the quarter compared to approximately $0.3 million from the prior year’s second quarter. The increase in research and development expenses was primarily attributable to an increase in preclinical activities for AnQlar, Probudur and Epoladerm, a milestone payment related to VRP324, and a slight increase in preclinical and regulatory activities for Envelta.

The operating loss for the second quarter of 2022 was approximately $5.9 million, as compared to $2.3 million for the same period a year ago.

Six Months Ended June 30, 2022 and 2021

Operating Expenses

General and administrative expenses were approximately $4.4 million for the six months ended June 30, 2022, an increase of about $1.2 million as compared to the six months ended June 30, 2021. The primary reason for the increase in general and administrative costs was the result of an increase in legal defense costs with regard to litigation, an increase in salaries and wages and employee benefits related to new hires and merit increases, an increase in insurance costs related to directors’ and officers’ insurance, an increase in non-executive board compensation, and an increase in grant writing and grant consulting fees. This was offset by a decrease in stock based compensation.

Research and development expenses increased by approximately $5.2 million to $6.6 million for the six months ended June 30, 2022, from $1.4 million for the six months ended June 30, 2021. The increase was primarily attributable to an increase in milestone payments related to AnQlar, an increase in preclinical activity related to AnQlar’s ongoing IND enabling studies, increases in preclinical and regulatory activity related to Epoladerm, an increase in preclinical work related to Probudur related to ongoing formula optimization, an increase in VRP324 mainly due to a milestone payment of $500,000 upon achieving the study aim contained within a pre-clinical animal study, and a slight increase in regulatory activities related to Envelta.

Cash Flows

Operating Activities

Cash used in operations was approximately $10.8 million for the six months ended June 30, 2022, compared to approximately $4.9 million for the six months ended June 30, 2021. The increase in cash used in operations was primarily the result of the increase in net loss and prepaid expenses and current assets, offset by an increase in accounts payable and accrued expenses.

Financing Activities

Cash provided by financing activities was approximately $15.3 million during the six months ended June 30, 2021, attributable primarily to net proceeds received from the Company’s initial public offering in February 2021 of approximately $15.8 million, after deducting underwriting discounts and offering expenses. This was slightly offset by repayment in full of the Company’s convertible promissory note of approximately $0.5 million in February 2021. No financing activities took place during the six months ended June 30, 2022.

At June 30, 2022, the Company had cash of approximately $26.1 million.
