Virpax Pharmaceuticals Reports 2023 First Quarter Results and Recent Developments

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 March 31, 2023, and other recent developments.

"Many of the initiatives that we have been actively working on were completed in the first quarter, and I believe that we are off to an excellent start in 2023," commented Anthony P. Mack, Chairman and Chief Executive Officer of Virpax. "We have built up our development teams with the addition of world-class experts to advise us, completed a number of studies that we believe will help us advance our Rx product candidates and engaged leading partnering and licensing advisors as we look to secure non-dilutive financing.

"Work on Probudur^™, our lead asset for postoperative pain management, has been steady and productive as we look to scale up production with our partner and still expect to initiate pre-clinical studies toward the end of this year," continued Mr. Mack. "Additionally, we have added two advisors to this program, Dr. Neil Singla and Dr. Pardeep Gupta. We expect that Dr. Singla, a leading pain expert, will assist in the design and support of the clinical development strategy. Dr. Pardeep, whose expertise is in liposomal drug delivery and nanotechnology, was brought on board to advise our team on chemistry, manufacturing and controls (CMC), technology transfer and commercial buildout.

With Envelta^™, the Company's non-opioid pain product candidate being developed under an in-kind grant from the National Center for Advancing Translational Sciences (NCATS), we successfully completed dose ranging studies in both rats and dogs. Intranasal administration, using our Molecular Envelope Technology (MET), demonstrated that it was well-tolerated and there were no adverse effects. We remain on track to file the Investigational New Drug (IND) application by the second quarter of 2024.

"For NobrXiol^™, we have engaged two leading experts in pediatric epilepsy, Dr. Kenneth Sommerville and Dr. Lawrence Fried, to help us advance this product candidate, as well as assist in our grant and cooperative research and development agreement (CRADA) submissions," added Mr. Mack.

"Lastly, I am pleased with the progress we are making in our efforts to secure non-dilutive financing. We currently have two CRADAs with the federal government and believe that we are well-positioned to receive additional ones as we continue to demonstrate success in our current drug development programs. As well, I am encouraged by the initial responses that both New England Investors and Destum Partners have received with respect to our out-licensing efforts," concluded Mr. Mack.

FINANCIAL RESULTS FOR THE THREE MONTHS ENDED MARCH 31, 2023

Operating Expenses

General and administrative expenses were approximately $0.4 million for the first quarter of 2023, a decrease of about 77% or $1.4 million from the first quarter of 2022. The decrease in general and administrative costs was primarily attributable to a decrease in legal costs due to reimbursement of legal costs pursuant to the Company's D&O insurance policy and a decrease in defense costs with regard to ongoing litigation, and to a lesser degree, a decrease in stock-based compensation and public relation costs. This was offset by an increase in fees related to market assessment efforts, as well as advisory and consulting fees, in addition to an increase in salaries, wages and employee benefits.

Research and development expenses were approximately $1.2 million, a decrease of about 63% or $2.1 million for the three months ended March 31, 2023, as compared to the prior year first quarter. The decrease was primarily attributable to a one-time milestone payment made to Nanomerics in the first quarter of 2022 related to the acquisition of global rights for AnQlar, a decrease in AnQlar preclinical activities, and to a lesser extent, a decrease in preclinical activity related to Epoladerm. This was slightly offset by an increase related to Probudur preclinical activities, as well as an increase in preclinical activity related to NobrXiol and to regulatory work related to Envelta.

Cash Flows

Operating Activities

Cash used in operations was approximately $2.0 million for the first quarter of 2023 compared to $6.0 million for the three months ended March 31, 2022. The decrease in cash used in operations was primarily the result of the decrease in net loss and a decrease in prepaid insurance and prepaid research and development costs. In addition, in March 2023, we collected $1,250,000 in reimbursement of legal costs pursuant to our directors' and officers' insurance policy which decreased our net loss during the period.

At March 31, 2023, Virpax had cash of approximately $17.0 million.
