Emergent BioSolutions Announces FDA Approval of Change in Storage Conditions and Transfer of Manufacturing for Its Cholera Vaccine

GAITHERSBURG, Md., June 04, 2019 (GLOBE NEWSWIRE) — Emergent BioSolutions Inc. (NYSE:EBS) today announced approval by the U.S. Food and Drug Administration (FDA) of the Prior Approval Supplement (PAS) submitted by the company for its oral cholera vaccine, Vaxchora^® (Cholera Vaccine, Live, Oral). The PAS supports the change in storage conditions of the vaccine from frozen to refrigerated at 2-8°C and the transfer of bulk drug substance manufacturing from Emergent’s product development facility in San Diego to its manufacturing facility in Bern, Switzerland. The PAS also covers changes in labeling regarding these developments. The company’s oral cholera vaccine is the only FDA-licensed vaccine for the prevention of cholera caused by Vibrio cholerae serogroup O1, a potentially serious intestinal disease.

“Emergent is pleased with this FDA approval that enables a more robust supply chain process for our oral cholera vaccine and maximizes capacity utilization of our manufacturing facilities,” said Sean Kirk, executive vice president, manufacturing and technical operations at Emergent BioSolutions. “This development positions the company to expand into new markets as we prepare for European launch in 2020.”

In the U.S., the vaccine is marketed as Vaxchora^®. The vaccine is indicated for active immunization against disease caused by Vibrio cholerae serogroup O1. Vaxchora^® is approved for use in adults 18 through 64 years of age traveling to cholera-affected areas. Limitations of Use: The effectiveness of Vaxchora^® has not been established in persons living in cholera-affected areas. The effectiveness of Vaxchora^® has not been established in persons who have pre-existing immunity due to previous exposure to V. cholerae or receipt of a cholera vaccine. Vaxchora^® has not been shown to protect against disease caused by V. cholerae serogroup O139 or other non-O1 serogroups. It was approved by the FDA in June 2016 as the only vaccine available in the U.S. for active immunization against cholera.

About Cholera
Cholera, transmitted by ingestion of food and water contaminated with Vibrio cholerae, may present with a broad range of symptoms. Cholera commonly presents as watery diarrhea, but may also be asymptomatic or, in severe cases, characterized by profuse watery diarrhea.ⁱ If untreated, these severe cases may lead to dehydration, hypovolemic shock and death within hours.ⁱ  With limited surveillance capacities, as well as social, economic and political disincentives, cholera is an underreported disease. The World Health Organization (WHO) estimates that only 5-10% of cases occurring annually are officially reported.^ii,iii Non-vaccine interventions to prevent cholera infection include the avoidance of contaminated water and food and frequent handwashing.ⁱ In May 2017, the CDC published its recommendation for the use of Vaxchora in adults 18-64 years traveling from the U.S. to areas of active cholera transmission.^iv
