Vaxart (VXRT) Stock Sees Solid Recovery In Extended Session: Here is Why

VXRT soared 23% in after-hours sessions as Vaxart Inc (NASDAQ:VXRT) reports data from oral COVID-19 vaccine Phase 1 study suggesting broad cross-reactivity against other coronaviruses.

Vaxart announced today at its key opinion leader event that new data obtained from its Phase I COVID-19 trial added to the evidence suggesting that VXA-CoV2-1, the company’s first COVID-19 oral vaccine construct that triggers mucosal immunity and includes both the S and the N SARS-Cov-2 proteins, has broad cross-coronavirus activity.

The Phase I open-label study is intended to evaluate the safety and immunogenicity of Vaxart’s vaccine candidate. Data obtained from Vaxart’s oral COVID-19 vaccine Phase I trial showed substantial CD8+ T-cell responses, as measured by IFN-g and TNF-a induction.

In a comparative experiment conducted by Vaxart, Phase I study data was compared to T-cell responses from volunteers subsequently vaccinated with the Moderna (MRNA) or Pfizer (PFE) mRNA vaccine, indicating the mRNA vaccines induced fewer T-cell responses.

After falling over 25.50% in regular trading on earnings miss, VXRT stock is up 23% in the extended session.
