--Company Highlights Development Timelines for Product Candidates--

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 September 30, 2022, and other recent developments.

“I believe that Virpax has made good progress this past year toward our stated goals,” commented Anthony P. Mack, Chairman and CEO of Virpax. “Our accomplishments include ongoing development of our existing product candidates, broadening our product pipeline, utilizing grants where appropriate, and assessing the potential of our product candidates for partnering with pharmaceutical companies in the animal health market. We recently separated our pipeline into Rx products that we intend to develop and commercialize in the U.S., and over-the-counter (OTC) products that we expect to license out or partner with a company that specializes in the OTC marketplace.

“From a financial perspective, we are judiciously managing our cash and expect to have sufficient funds to advance our programs for at least 12 months from the filing of our Form 10-Q for the period ended September 30, 2022, exclusive of any potential future grants, Cooperative Research and Development Agreements (CRADAs) or licensing fees we may pursue, if appropriate. We have global rights for all of our product candidates and therefore we believe there are opportunities to pursue ex-U.S. companies for potential licensing deals.

“While we recently filed an S-3 shelf registration statement with the SEC, this filing was done to ensure financial flexibility. Our focus remains on our strategy of raising non-dilutive financing to progress our clinical pipeline,” continued Mr. Mack.

“We have an enthusiastic and committed team, numerous ongoing preclinical trials, and are actively moving our product candidates forward with the possibility of starting human clinical trials sometime in 2023,” concluded Mr. Mack.

Rx Pipeline

Probudur™

Probudur is an injectable bupivacaine liposomal hydrogel for postoperative pain management which Virpax believes has improved onset and extended duration of action compared to existing treatment options. The Company engaged Charles River Laboratories to perform preclinical animal studies as part of required FDA investigational new drug (IND) enabling trials. Virpax strategically delayed the start of these trials in order to improve the formulation to potentially enhance manufacturing efficiencies, prolong duration and extend patent protection. The Company anticipates the relevant patent to be filed during the first half of 2023. Additionally, Lipocure, from whom the Company licenses the unique bupivacaine liposome hydrogel, is in the process of scaling up production of the enhanced formulation in anticipation of starting IND-enabling studies in the third quarter of 2023.

In addition, Virpax entered into a CRADA with the U.S. Army Institute of Surgery (USAISR) in April of 2022. The research project will evaluate the analgesic and physiological effects of Probudur for battlefield injury induced pain as a long-lasting local anesthetic for use in battlefield trauma and critical care.

Envelta™

Envelta is an endogenous enkephalin intranasal spray for acute and chronic pain, including pain associated with cancer. This product leverages Nanomerics’ Molecular Envelope Technology (MET) platform, which Virpax licensed, to deliver the endogenous enkephalin formulation through an intranasal delivery device enabling the enkephalin to cross the blood-brain barrier via the olfactory route while bypassing the liver. This product candidate is being funded through an in-kind CRADA with the National Institutes of Health's (NIH) National Center for Advancing Translational Sciences (NCATS) entered into by Virpax and the NIH in August of 2020.

To date, four in vitro studies have been completed along with an in vivo acute efficacy study. Two dose range finding studies in rats and dogs have also been successfully completed with no adverse toxicologic findings. In vivo chronic efficacy studies are being planned and it is expected that they will be completed in the first quarter of 2023.

In addition to the ongoing studies, NCATS in collaboration with Virpax is working on the necessary preclinical manufacturing work and NCATS is working with its manufacturer on scaling up production of Envelta with expected completion in the second half of 2023. An IND filing of Envelta is currently anticipated for the first quarter of 2024.

VRP324

Virpax has acquired the exclusive worldwide rights from Nanomerics to use Nanomerics’ MET platform for the nasal delivery of cannabidiol (CBD) for the management of epilepsy in children (a rare pediatric disease) and adults. As part of this agreement, Nanomerics is developing an investigational formulation delivered via the nasal route to enhance CBD transport to the brain which could potentially eliminate any drug interaction issues and bypass the digestive system, possibly eliminating many of the side effects associated with the product currently in use on the market. Nanomerics demonstrated the ability of its platform technology to deliver CBD directly to the brain in an animal model.

Virpax prepared and submitted the pre-IND briefing documents to the FDA in October 2022 and expects to receive a response in December 2022.

OTC Pipeline

Epoladerm™

Epoladerm is a diclofenac topical spray film that is being developed as an OTC product candidate for pain associated with osteoarthritis of the knee. In December of 2021, the Company executed a clinical trial agreement with Altasciences Company, Inc. to conduct a study in Canada. We have experienced delays in initiating enrollment for this clinical study that were initially due to a delay in procuring the active pharmaceutical ingredient necessary for the drug product candidate and delays related to supply chain disruptions. Additionally, we recently discovered a degradant issue after an extensive review of the formulation.

MedPharm, from whom the Company licenses the product, is working on a revised formulation. This work is expected to be completed in the first quarter of 2023. Assuming a successful reformulation, MedPharm will begin manufacturing batches of the product candidate that Virpax expects to use in their First-in-Human study now anticipated to begin towards the end of 2023.

AnQlar™

AnQlar (formerly MMS019) is a high-density intranasal molecular masking spray in development as an OTC Intranasal Medical Device product for protection against respiratory infections, such as SARS-CoV-2 and influenza. Virpax anticipates that AnQlar will be used as an adjuvant to barrier-based personal protective equipment. While Virpax has successfully completed a number of required pre-clinical studies for its OTC medical device application, the Company anticipates that it will have to complete stability testing, human factor testing for medical devices, safety studies and supplementary in-vitro studies.

We may seek to out-license or partner both Epoladerm and AnQlar as we continue to focus our efforts on our prescription drug pipeline.

FINANCIAL RESULTS

Three Months Ended September 30, 2022

Operating Expenses

General and administrative expenses were approximately $4.9 million for the third quarter of 2022, an increase of about $3.4 million from the prior year’s third quarter. The increase was due to legal expenses and an accrual of an estimated litigation liability, compensation expense, insurance costs and board of director fees.

Research and development expenses were approximately $2.8 million in the quarter compared to approximately $1.7 million from the prior year’s third quarter. The increase in research and development expenses was primarily attributable to an increase in preclinical activities for AnQlar, offset by a decrease in preclinical work related to Probudur, a decrease in preclinical and regulatory activities related to Epoladerm, a decrease in VRP324 mainly due to a milestone payment paid to Nanomerics in the prior period and a slight decrease in regulatory activities related to Envelta.

The operating loss for the third quarter of 2022 was approximately $7.7 million, as compared to $3.2 million for the same period a year ago.

Nine Months Ended September 30, 2022

Operating Expenses

General and administrative expenses were approximately $9.3 million for the nine months ended September 30, 2022, an increase of about $4.5 million as compared to the nine months ended September 30, 2021. The increase in general and administrative costs was the result of an increase in litigation defense efforts due to legal fees and the accrual of an estimated litigation liability, an increase in salaries and wages and employee benefits, an increase in insurance costs for directors’ and officers’ insurance, an increase in non-executive board compensation, and an increase in grant writing and grant consulting fees. This was slightly offset by a decrease in stock-based compensation.

Research and development expenses increased by approximately $6.3 million to $9.4 million for the nine months ended September 30, 2022, from $3.1 million for the nine months ended September 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 and regulatory consulting, increases in preclinical and regulatory activity related to Epoladerm, an increase in preclinical work for Probudur related to ongoing formula optimization, an increase in VRP324 due to a milestone payment, and a slight increase in regulatory activities related to Envelta.

Cash Flows

Operating Activities

Cash used in operations was approximately $16.3 million for the nine months ended September 30, 2022, compared to approximately $9.6 million for the nine months ended September 30, 2021. The increase in cash used in operations was primarily the result of the increase in net loss, prepaid expenses and current assets offset by an increase in accounts payable and accrued expenses.

Financing Activities

Cash provided by financing activities was approximately $51.3 million during the nine months ended September 30, 2021, attributable primarily due to net proceeds received from our initial public offering in February 2021 and an underwritten public offering in September 2021, after deducting all underwriting discounts and offering expenses. This was slightly offset by repayment in full of an outstanding promissory note of approximately $0.5 million in February 2021. No financing activities took place during the nine months ended September 30, 2022.

At September 30, 2022, the Company had cash of approximately $20.6 million.
