Vaxart initiates PhI trial of oral influenza B vaccine

South San Francisco-based Vaxart said it has enrolled the first patient in a Phase I trial of the company's oral influenza B vaccine candidate. According to a statement, the vaccine represents the last monovalent component the company needs before it can advance with the development of its quadrivalent influenza vaccine tablet. Recent findings published in The Lancet Infectious Diseases demonstrated that the company's influenza A tablet vaccine generated neutralizing antibodies and a mucosal immune response in 92% of people after one dose; the influenza B vaccine is based on the same platform. The company says its room temperature-stable tablet vaccines may be as protective as currently marketed flu vaccines but can offer distribution and administration advantages. In October, it was awarded $14 million from BARDA to develop its flu tablet vaccines, money that will support a Phase II trial, the statement said.
