First Oral Norovirus GII.4 Tablet Vaccine Used
in Clinical Trial
Vaxart, Inc., a clinical-stage biotechnology company developing
oral recombinant vaccines that are administered by tablet rather
than by injection, today announced the completion of dosing of the
lead-in cohort in the Phase 1b bivalent norovirus vaccine clinical
trial with its oral norovirus GII.4 vaccine.
The Vaxart bivalent norovirus vaccine consists of an oral
norovirus GI.1 vaccine and an oral norovirus GII.4 vaccine
administered concurrently by tablet. The bivalent norovirus Phase
1b trial consists of two parts, an open-label lead-in phase which
has now been completed, and a randomized, double-blind,
placebo-controlled phase which is expected to start in April,
subject to final review by the FDA. Both portions of the trial are
designed to evaluate safety and immunogenicity. The Company expects
to receive topline data from the trial in the second half of
2019.
About Norovirus
Norovirus is recognized as a leading cause of acute
gastroenteritis in the United States. It is a common intestinal
infection that typically lasts three to five days and is marked by
diarrhea, vomiting, abdominal cramps, nausea and sometimes fever.
Symptoms can be more severe in older adults and young children and
may lead to serious complications including death. Norovirus causes
frequent and widespread outbreaks in the military, food industry,
travel industry, child care facilities, elderly homes and
healthcare facilities.
The U.S. Centers for Disease Control and Prevention (CDC)
estimates that norovirus causes approximately 19 to 21 million
illnesses in the United States each year, resulting in 56,000 to
71,000 hospitalizations and 570 to 800 deaths, mostly among young
children and older adults. In a recent study by Johns Hopkins
University and the CDC, researchers estimated the global economic
impact of norovirus disease at $60 billion, $34 billion of which
occurred in high income countries, including the United States,
Europe and Japan.

Vaxart is a clinical-stage biotechnology company focused on
developing oral recombinant protein vaccines based on its

to generate broad and durable immune responses that protect against
a wide range of infectious diseases and may also be useful for the
treatment of chronic viral infections and cancer. Vaxart’s vaccines
