Sinovac Dalian receives approval to start human clinical trials of varicella vaccine candidate

 

Sinovac Biotech Ltd. (NASDAQ: SVA), a leading provider of biopharmaceutical products in China, today announced that one of its subsidiaries, Sinovac Dalian, has received approval to begin human clinical trials on its varicella vaccine candidate. The clinical trial application for the varicella vaccine was officially accepted by the China Food and Drug Administration (CFDA) in January 2013.

In preparation to begin human clinical trials, Sinovac Dalian is currently finalizing the trial protocol, confirming the site, training staff and preparing for volunteer screening. The Company expects to complete the trial in 2017. Simultaneously, Sinovac Dalian is renovating of an existing building on its Dalian campus, which will serve as the commercial production plant for the varicella vaccine. The plant will have a designed annual capacity of 5 million doses.

The Company's varicella vaccine candidate is a live attenuated vaccine derived from a human cell line. Development of the vaccine began in 2010 and the clinical trial application was officially accepted by the CFDA in January 2013, after the preclinical study was completed. The Company expects to be able to commercialize its varicella vaccine by the end of 2019. Ultimately, Sinovac plans to develop a measles-mumps-rubella-varicella (MMRV) combination vaccine. The Company has licensed a mumps vaccine for sale in China, has clinical trial approval for its internally-developed rubella vaccine and plans to begin development of a measles vaccine.

Currently, the varicella vaccine is sold exclusively in the private-pay market in China by four domestic producers. In some regions, the varicella vaccine is included in the emergency immunization programs of several provinces for free vaccination due to outbreaks. According to the China CDC, the varicella vaccine is recommended to children over 12 months with different immunization schedules implemented in different provinces and it's specified in the product specification. Generally, a one-dose scheme is recommended for children from 12 months to 12 years old and two doses for those 13 years and older. Recently, one booster shot has been recommended for children 4 to 12 years old by some local CDCs. This is expected to become standard protocol throughout the country in the coming years, which would increase market demand. In the past five years, approximately 15-16 million doses were released to China market annually.

Mr. Weidong Yin, Chairman, President and CEO of Sinovac, commented, "Obtaining the clinical trial approval marks a significant step in the R&D process for our varicella vaccine candidate. Once commercialized, this vaccine will be supplied to the existing market demand and support Sinovac Dalian for its asset utilization, cash flow and profitability in the near future, and position us to capture share with the potential market expansion in the coming years. Meanwhile, there is a meaningful opportunity for an MMRV vaccine in the private-pay market in the future. This represents another milestone as we further develop our vaccine product portfolio to fulfill China's unmet medical needs."
