Baxter International Inc. (NYSE: BAX) today announced that it completed production of its first commercial batches of CELVAPAN A/H1N1 pandemic vaccine in late July and is discussing plans for distribution with national health authorities, subject to obtaining appropriate authorizations. CELVAPAN, the brand name for the company’s A/H1N1 pandemic influenza vaccine, is made using Baxter’s proprietary Vero cell culture technology.
Baxter plans to deliver initial quantities of CELVAPAN to national public health authorities that have pandemic agreements with the company. These health authorities placed orders for the vaccine following the World Health Organization’s (WHO) elevation of the pandemic alert level to phase 6 and declaration of a pandemic.
Baxter’s proprietary Vero cell production technology is meeting the company’s expectations to rapidly produce a vaccine in response to a pandemic. CELVAPAN was developed and commercially produced using this process within 12 weeks of receiving the A/H1N1 virus strain, which represents an innovation in vaccine production.
“We are pleased with our company’s ability to meet its expected timelines in developing and producing CELVAPAN,” said Joy Amundson, corporate vice president and president of Baxter BioScience. “This is an encouraging validation of our science, our Vero cell vaccine technology and the teamwork at Baxter in meeting this important milestone to help address an urgent public health issue.”
Baxter is collaborating with regulatory authorities to ensure the company is in accordance with all requirements needed to support approval and use of CELVAPAN. “To make CELVAPAN A/H1N1 vaccine, we applied the same development, qualification and manufacturing processes used in gaining European Medicines Agency (EMEA) licensure of a mock-up pandemic vaccine,” said Hartmut J. Ehrlich, M.D., vice president of global research and development for Baxter BioScience. “The mock-up vaccine made with a different pandemic strain was tested in five clinical trials worldwide in more than 1,300 people. In addition, more than 3,500 people have been vaccinated during an ongoing phase III study.”
