First Oral COVID-19 Tablet Vaccine in Phase 1 Trial

October 13, 2020

South San Francisco-based Vaxart announced today it has given its first participant its investigational, oral COVID-19 tablet vaccine, VXA-CoV2-1.

“We are advancing VXA-CoV2-1 into clinical development based on the strength of pre-clinical data that showed that the vaccine is capable of inducing both a robust systemic immune response and a strong mucosal immune response, specifically in the lungs,” Sean Tucker, PhD, chief scientific officer and founder of Vaxart, said. “We are eager to explore the clinical profile of VXA-CoV2-1 for effective protection against SARS-CoV-2 infection and transmission in healthy adults.”

The company has entered a phase 1, open-label, dose-ranging trial and is expecting to finish in November of this year. The trial is going to examine the safety and immunogenicity of 2 doses of VXA-CoV2-1 in up to 48 healthy adult volunteers aged 18 to 54 years old.

All participants will be receiving the low or high dose of the VXA-CoV2-1 oral tablet at days 1 and 29. Safety, reactogenicity and immunogenicity assessments will be performed at set times during the active phase.
