Vaxart Provides Update on its Oral COVID-19 Vaccine Program
- Five COVID-19 Vaccine Candidates in Preclinical Testing
- Development Services to Enable Manufacture of cGMP Vaccine at Emergent BioSolutions have Started
SOUTH SAN FRANCISCO, Calif., March 31, 2020 (GLOBE NEWSWIRE) -- Vaxart, Inc., a clinical-stage biotechnology company developing oral recombinant vaccines that are administered by tablet rather than by injection, today announced it had produced five COVID-19 vaccine candidates for testing in its preclinical models. Each of the COVID-19 vaccine constructs is based on a different coronavirus antigen combination, and Vaxart expects to advance the best performing vaccine to manufacturing for clinical trials.
“The effectiveness of Vaxart’s oral vaccine technology has been demonstrated in clinical trials. Developing a vaccine to meet this current public health threat is very important to all of us at Vaxart,” said Sean Tucker, Ph.D., chief scientific officer of Vaxart. “Our scientists have been working tirelessly to develop these 5 different vaccine constructs, and this evaluation in our preclinical models will allow us to select the most potent candidate for clinical testing.”
In January, Vaxart initiated a program to develop a COVID-19 vaccine based on its VAASTTM platform. On March 18, Vaxart announced that it had entered into an agreement with Emergent BioSolutions Inc. (“Emergent”) for development services in preparation for the cGMP production of the Vaxart vaccine. Development services have started and, if Vaxart elects to proceed with cGMP manufacturing, Emergent is expected to produce bulk cGMP vaccine for use in a Phase 1 clinical study that Vaxart currently expects to initiate early in the second half of 2020.
“We believe an oral vaccine administered using a room temperature-stable tablet would provide enormous logistical advantages in large vaccination campaigns,” said Wouter Latour, MD, chief executive officer of Vaxart Inc. “Perhaps more importantly, we recently demonstrated that our oral H1 influenza vaccine protects against respiratory infection based on mucosal immunity, the first line of defense for “mucosal” viruses like influenza and this new coronavirus. We believe this puts Vaxart in a unique position to develop an effective vaccine that protects the population from COVID-19.”
CDC is responding to a pandemic of respiratory disease spreading from person-to-person caused by a novel (new) coronavirus. The disease has been named “coronavirus disease 2019” (abbreviated “COVID-19”). This situation poses a serious public health risk. The federal government is working closely with state, local, tribal, and territorial partners, as well as public health partners, to respond to this situation. COVID-19 can cause mild to severe illness; most severe illness occurs in older adults.
Vaxart is a clinical-stage biotechnology company primarily 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 tablet 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 coronavirus, norovirus, seasonal influenza and respiratory syncytial virus (RSV), as well as a therapeutic vaccine for human papillomavirus (HPV).
