SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--Apr. 16, 2019--
Vaxart, Inc., a clinical-stage biotechnology company developing oral
recombinant vaccines that are administered by tablet rather than by
injection, today announced it has started dosing subjects in the
randomized cohort of the Phase 1b bivalent norovirus vaccine clinical
trial.
“We are delighted to start the randomized portion of the bivalent
norovirus phase 1b trial,” said David Taylor, M.D., chief medical
officer of Vaxart. “The monovalent GII.4 vaccine tablets performed as
expected in the lead-in cohort we just completed, and we look forward to
building on the excellent results we observed previously with our
monovalent GI.1 vaccine. Norovirus is the leading cause of foodborne
illness in the United States and causes significant morbidity and
mortality in older adults and the very young. Our oral norovirus vaccine
could provide a significant public health benefit for these vulnerable
populations in the United States and beyond.”
The Vaxart bivalent norovirus vaccine consists of an oral norovirus GI.1
vaccine tablet and an oral norovirus GII.4 vaccine tablet administered
concurrently. The bivalent norovirus Phase 1b trial includes two stages,
an open-label lead-in phase which was completed successfully earlier
this month, and a randomized, double-blind, placebo-controlled phase
which has now started. 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 the 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 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.
