VRPX Stock Halted Repeatedly As Shares Rocket Out of Penny Stock Territory

Written by Staff

VRPX Stock: Key Takeaways

  • Virpax Pharmaceuticals completes the first step with the FDA toward approval of its product to prevent transmission of viruses like COVID-19 and influenza. 
  • Animal studies have shown success with no adverse effects reported. 
  • VRPX stock surges more than 280% as the company says it’s preparing for human clinical trials.

Virpax Pharmaceuticals, Inc. (NASDAQ: VRPX) more than tripled today on FDA-related news about its anti-viral barrier product.

Trading of VRPX stock was halted repeatedly in today’s session, and at writing, shares were up more than 286%. 


The rally comes after Virpax announced it received a written pre-investigational new drug (pre-IND) response from the FDA for MMS019. 

Blocking Transmission of Viruses Like COVID

MMS019 is Virpax’s “patented and proprietary high-density molecular masking spray under development for use as an anti-viral barrier product” to prevent transmission of viruses like COVID-19 and influenza. 

It’s a nasal spray type of treatment “based on a type of nanotechnology that enables the exclusive delivery of a metabolically labile peptide drug into the brain.”

Previous in-vitro, ex-vivo (human mucosal cells), and in-vivo trials for MMS019 “demonstrated inhibition of viral replication of SARS-CoV-2 and influenza in animals at much higher ranges than what is encountered by humans in the nasal passages.”

The company says no adverse effects were observed during those studies.

The animal studies also “demonstrated inhibition of viral replication of SARS-CoV-2 and influenza in animals at much higher ranges than what is encountered by humans in the nasal passages.”

Virpax said it “believes the results of the pre-IND response support further research on MMS019 as an intranasal protective that may limit transmission of the viruses to others.”

Now Virpax plans to pursue a New Drug Application (NDA) to approve MMS019 as a daily intranasal treatment. 

The FDA said that approval can come from the Office of Non-Prescription Drugs and Virpax is working with Syneos Health to assist with the optimal clinical trial design for humans.

The FDA’s pre-IND guidance helps ensure a drug’s clinical trials and studies meet the agency’s requirements for future approval.

Virpax’s chairman and CEO Anthony P. Mack said, “We are very pleased with the response from the FDA. We believe that the initial pathway to move forward with the development of MMS019 has been clarified.  The pre-IND meeting provides an opportunity for open communication between the Sponsor and the FDA to discuss the IND development plan and to obtain the FDA’s guidance for clinical studies for the new drug candidate.”

Mack said the company plans to seek approval for the drug as an over-the-counter treatment rather than a prescription drug.
