“We are off to a strong start in 2024 and are pleased to have regained compliance with Nasdaq. Additionally, we have executed a settlement agreement with the Plaintiffs, and can now focus on developing our non-addictive product candidates for pain management,” commented Gerald W. Bruce, Chief Executive Officer of Virpax.

“Recently we reported the initial results from the pilot study of Probudur^™ performed by the U.S. Army Institute of Surgical Research (USAISR). The findings were in line with our expectations and support our earlier studies of Probudur. We are excited for the USAISR’s next study which as planned would be a head-to-head comparison with free bupivacaine and EXPAREL^® and expect it to start mid-year,” continued Mr. Bruce. “As of today, we are still on track to file the IND later in 2024.”

“We are continuing to develop Envelta^™, our non-addictive pain product candidate for acute and chronic pain, with the NIH under our NCATS in-kind grant and are making progress towards filing the IND,” added Mr. Bruce.

“Virpax has developed a core competency in identifying, applying for and winning government grants. We continue to apply for funding when we believe we have a strong chance of success. Currently, there are a number of applications that we continue to work on while we await decisions on those that have been previously submitted. This strategy has proven to be an excellent source of non-dilutive funding and we will continue to pursue it.

“We are also continuing to work with our partners identifying and evaluating sublicensing options. Together, we are making progress with our lead pain assets in both the global animal healthcare market as well as assessing potential geographical opportunities.

“We expect to achieve some significant milestones this year and look forward to sharing them. Our team is committed to the important and potentially game-changing product candidates that are under development, and their efforts are greatly appreciated,” concluded Mr. Bruce.

RECENT DEVELOPMENTS

FINANCIAL RESULTS FOR THE YEARS ENDED DECEMBER 31, 2023, AND 2022

Twelve Months Ended December 31, 2023

Operating Expenses

General and administrative expenses were $10.6 million for the year ended December 31, 2023, compared to $11.1 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, severance, and professional fees.

Research and development expenses were $5.1 million for the year ended December 31, 2023, compared to $10.8 million for the same period in 2022. The decrease was primarily attributable to a milestone payment in 2022 related to AnQlar and decreases in preclinical activities for AnQlar, NobrXiol, and Epoladerm. This was partially offset by an increase in preclinical activity for Probudur.

The operating loss for the year ended December 31, 2023, was $15.2 million, compared to an operating loss of $21.7 million for the same period in 2022.

As of December 31, 2023, Virpax had cash of approximately $9.1 million, compared to $19.0 million as of December 31, 2022.

About Virpax Pharmaceuticals

Virpax is developing branded, non-addictive pain management products candidates using its proprietary technologies to optimize and target drug delivery. Virpax is initially seeking FDA approval for two prescription drug candidates that employ two different patented drug delivery platforms. Probudur™ is a single injection liposomal bupivacaine formulation being developed to manage post-operative pain and Envelta™ is an intranasal molecular envelope enkephalin formulation being developed to manage acute and chronic pain, including pain associated with cancer. Virpax is also using its intranasal Molecular Envelope Technology (MET) to develop one other prescription product candidate, NobrXiol™, which is being developed for the nasal delivery of a pharmaceutical-grade cannabidiol (CBD) for the management of rare pediatric epilepsy. Virpax has competitive cooperative research and development agreements (CRADAs) for two of its prescription drug candidates, one with the National Institutes of Health (NIH) and one with the Department of Defense (DOD). Virpax is also seeking approval of two nonprescription product candidates: AnQlar, which is being developed to inhibit viral replication caused by influenza or SARS-CoV-2, and Epoladerm™, which is a topical diclofenac spray film formulation being developed to manage pain associated with osteoarthritis.
