Virpax^® Pharmaceuticals, Inc. (“Virpax” or the “Company”) (NASDAQ: VRPX), a company specializing in developing non-addictive products for pain management, post-traumatic stress disorder, central nervous system (CNS) disorders and viral barrier indications, today announced its financial results for the three months ended September 30, 2023, and other recent developments.

“We recently announced results from two preclinical studies for Probudur^™, our lead product candidate for post operative pain, that demonstrated significantly longer efficacy in animal models than the product currently on the market today. With these solid results, we believe we are on track to file our Investigational New Drug (IND) Application and begin our Phase 2 trials of Probudur in 2024 upon completion of a few ongoing and planned additional studies,” commented Anthony P. Mack, Chairman and Chief Executive Officer of Virpax.

“Additionally, following our pre-IND meeting with the FDA, we expect to submit an IND for Envelta^™, our non-addictive pain product candidate for acute and chronic pain, in mid-2024 and initiate first in human trials in 2024. We are grateful for the support and collaboration from the National Institutes of Health (NIH) in the development of Envelta as a safe and effective alternative for opioids and are excited to continue to advance this program with them.”

“Earlier this year, we announced that we had hired two firms to assist us in developing licensing opportunities for both our Rx and OTC product candidates. We have had strong interest from potential licensing partners and are encouraged by the current level of activity,” continued Mr. Mack. “Finally, we have grant programs for each of our Rx product candidates as part of our non-dilutive funding strategy. We believe this is an important validation of our assets and continue to pursue additional grant funding where we believe we have a strong chance of winning the grant. Virpax continues to make progress across the board, and we look forward to sharing our results with all of our shareholders.”

RECENT DEVELOPMENTS

• On October 31, 2023, Virpax announced that it expects to submit an IND for Envelta in mid-2024 following review of comments made by the US Food and Drug Administration on the Company’s Pre-IND submission. If successful, that would allow clinical trials to begin by the middle of 2024. Envelta is the Company’s non-addictive pain product candidate for acute and chronic pain that is being funded under an in-kind grant from the National Center for Advancing Translational Sciences (NCATS), part of the NIH.

• On October 12, 2023, Virpax announced that the 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 formulation that is injected at the wound site, has been extended to September of 2024. The USASIR is the U.S. Department of Defense’s primary laboratory for developing solutions for trauma and critical care challenges in combat casualties.

• On October 2, 2023, the Company announced Gerald W. Bruce has been appointed as President and CEO of Novvae^™ Pharmaceuticals, Virpax’s wholly-owned subsidiary focused solely on advancing the Company’s OTC pipeline. Mr. Bruce has over 30 years’ experience in the pharmaceutical and medical nutrition industries primarily in commercial strategy, sales, and marketing.

• On September 27, 2023, Virpax announced results for two pre-clinical Probudur^™ dose escalation studies. Results from the first study utilizing a planar incision model compared Probudur to Exparel^® and demonstrated three times longer efficacy for Probudur than Exparel. In the second study, two different formulations at the same dose of Probudur were compared to Exparel in rat incision models and exhibited a four to five times longer effect than the comparable product.

• On August 10,2023, Virpax announced that it filed a new provisional patent application with the United States Patent and Trademark Office (USPTO) entitled “NSAID Formulation and Method” related to its Epoladerm^™ product candidate. Epoladerm is an over-the-counter diclofenac topical spray film that the Company is developing for pain associated with Osteoarthritis.

• On July 24, 2023, Virpax rang the Nasdaq closing bell.

• On July 13, 2023, Virpax announced that it had filed a new provisional patent application with the USPTO entitled “Intranasal Delivery” related to its Envelta^™ product candidate. Envelta utilizes Molecular Envelope Technology (MET) for the delivery of Enkephalin intranasally with a delivery device which propels the formulation into nose such that the enkephalin is delivered directly to the brain.

THIRD QUARTER 2023 FINANCIAL RESULTS

General and administrative expenses were $4.6 million for the three months ended September 30, 2023, compared to $4.9 million for the same period in 2022. The decrease was primarily due to lower legal defense costs related to litigation, net of litigation accrual, and was partially offset by an increase in salaries and wages, board of directors’ fees, travel expenses, stock-based compensation, and professional fees.

Research and development expenses were $1.5 million for the three months ended September 30, 2023, compared to $2.8 million for the same period in 2022. The decrease was primarily attributable to decreases in preclinical activities for AnQlar, NobrXiol, and Epoladerm. This was partially offset by an increase in preclinical activity related to Probudur.

The operating loss for the three months ended September 30, 2023, was $6.1 million, compared to an operating loss of $7.7 million for the same period in 2022.

As of September 30, 2023, cash and cash equivalents were $12.2 million, compared to $19.0 million as of December 31, 2022.
