On Sept. 14, 2020, Vaxart announced that the U.S. Food and Drug Administration (FDA) has completed its review of the Company’s Investigational New Drug (IND) application for its Phase 1 clinical trial evaluating its oral COVID-19 vaccine candidate. The Company also provided an update on its COVID-19 program.

The Phase 1, open-label, dose-ranging study will be conducted in healthy adults ages 18 to 55 years old. The study’s primary objective is to examine the safety and reactogenicity of two-doses of the vaccine. Secondary objectives include immunogenicity, duration of immune response and occurrence of symptomatic COVID-19.

Vaxart is conducting a SARS-CoV-2 challenge study in hamsters to provide efficacy data and insights into the optimal dose regimen of our vaccine candidate.  Results from this study, which began in early August, are expected mid-October.

In addition, and as previously disclosed, Vaxart is awaiting results from a non-human primate (NHP) challenge study that is testing its vaccine in a harmonized protocol as part of Operation Warp Speed. This preclinical program is being conducted in collaboration with the Biomedical Advanced Research and Development Authority (BARDA) and other entities working with Operation Warp Speed.

Vaxart is a clinical-stage biotechnology company developing a range of oral recombinant vaccines based on its proprietary delivery platform. Vaxart vaccines are administered using convenient room temperature-stable tablets that can be stored and shipped without refrigeration and eliminate the risk of needle-stick injury. Vaxart has demonstrated that its proprietary tablet vaccine delivery platform is suitable to deliver recombinant vaccines, positioning the company to develop oral versions of currently marketed vaccines and to design recombinant vaccines for new indications. Its development programs currently include tablet vaccines designed to protect against coronavirus, norovirus, seasonal influenza and respiratory syncytial virus (RSV), as well as a therapeutic vaccine for human papillomavirus (HPV), Vaxart’s first immuno-oncology indication. Vaxart has filed broad domestic and international patents covering its proprietary technology and creations for oral vaccination using adenovirus and TLR3 agonists.
