Vaxart to Present Clinical Data From its Norovirus Phase 1b Study at Three Global Healthcare Conferences in October 2019

October 1, 2019 at 8:00 AM EDT
ID Week (Washington, DC), 7th International Calicivirus Conference (Sydney, AU) and the 10th International Vaccines for Enteric Diseases (Lausanne, CH)
 

SOUTH SAN FRANCISCO, Calif., Oct. 01, 2019 (GLOBE NEWSWIRE) -- Vaxart, Inc. (NASDAQ: VXRT), a clinical-stage biotechnology company developing oral recombinant vaccines that are administered by tablet rather than by injection, today announced it will be presenting data from the recently completed phase 1b study with its bivalent norovirus GI.1/GII.4 vaccine at three prominent healthcare conferences.  As announced previously, all primary and secondary endpoints for safety and immunogenicity were met in the phase 1b study.  The new norovirus GII.4 component of the vaccine elicited IgA antibody secreting cells (ASC) in 90 – 93% of subjects.  The norovirus GI.1 component performed in line with previous phase 1 studies, eliciting IgA ASCs in 78 – 86% of subjects.  IgA ASCs are a marker for mucosal immunity and a potential correlate of protection against norovirus disease.

The company will be presenting at the following conferences:

About International Calicivirus Conference
The conference will bring together scientists, industry representatives and clinicians from all continents researching basic, applied, clinical and environmental aspects of viruses belonging to the family Caliciviridae.

About VED 2019
Vaccines for Enteric Diseases (VED 2019), will address the diverse aspects of vaccines to counter human enteric diseases. With regard to global public health issues, enteric diseases probably represent the first cause of infectious morbidity and second cause of infectious mortality worldwide. The added complications surrounding the increasing resistance to bacterial enteric pathogens to antibiotics are creating a worldwide trend that will require enhanced enteric vaccine strategies.  

About Vaxart
Vaxart is a clinical-stage biotechnology company focused on developing oral recombinant protein vaccines based on its proprietary oral vaccine platform. Vaxart’s vaccines are designed 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 are administered using a convenient room temperature-stable tablet, rather than by injection. Vaxart believes that tableted vaccines are easier to distribute and administer than injectable vaccines and have the potential to significantly increase vaccination rates. Vaxart’s development programs include oral tablet vaccines that are designed to protect against norovirus, seasonal influenza and respiratory syncytial virus (RSV), as well as a therapeutic vaccine for human papillomavirus (HPV).  For additional information please visit www.vaxart.com

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 high-risk patients (older adults and young children) and may lead to serious complications, including death. Norovirus causes frequent, debilitating and widespread outbreaks in the military, food industry, travel industry, childcare 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.
