Novavax (NVAX) stock skyrocketed 17.28% in early trading on Wednesday, following positive developments in the company's pursuit of FDA approval for its COVID-19 vaccine. The surge comes amid renewed optimism about the potential authorization of Novavax's Biologics License Application (BLA).

In a recent SEC filing, Novavax revealed that the U.S. Food and Drug Administration (FDA) has requested a post-marketing commitment (PMC) for additional clinical data on its COVID-19 vaccine. Despite this request, the company remains confident in the approvability of its BLA. Novavax stated, "We believe that our BLA is approvable based on conversations with FDA, as of our PDUFA date on April 1 and through today." This statement suggests positive ongoing discussions with the regulatory body.

Investors are interpreting the FDA's request for post-marketing data as a sign that approval may be imminent, with additional studies to be conducted after the vaccine reaches the market. Novavax's proactive stance in engaging with the FDA to address the PMC request has further boosted market confidence. As the company navigates the final stages of the regulatory process, the significant stock price increase reflects growing optimism about the potential commercial success of Novavax's COVID-19 vaccine.
