Sinovac Announces Positive Results From Phase III Trial Of a Sabin Strain-Based

Inactivated Polio Vaccine (sIPV) Published in the Journal of Infectious Disease

 

·The Sinovac-developed sIPV demonstrates both long-term affordability and accessibility and has the potential to contribute significantly to polio eradication in developing countries and the progress towards a polio-free world.

 

April 16, 2019 08:00 AM Eastern Daylight Time

 

BEIJING--(BUSINESS WIRE)--Sinovac Biotech Ltd. (SVA) ("Sinovac" or the "Company"), a leading provider of biopharmaceutical products in China, today announced that the positive results from the Company’s Phase III clinical study of a Sabin strain-based inactivated polio vaccine (sIPV) developed by Sinovac were published in the Journal of Infectious Disease. With Sinovac’s sIPV, efficacy is maintained while common risks associated with legacy vaccines can be mitigated. In comparison to oral polio vaccine (OPV), inactivated polio vaccine (IPV) contains no live virus and thus carries no risk of vaccine-derived poliovirus (VDPV) emergence or vaccine-associated paralytic polio (VAPP). The study found that the immune responses against the three types of poliovirus in the studied sIPV were not inferior to those achieved with the control IPV and demonstrated a good safety profile.

 

This research implies that the studied sIPV is as effective as IPV in preventing poliovirus infection in infants aged 60–90 days, can be a reliable alternative to conventional IPV and can be a good supplement to OPV in potentially preventing or minimizing VDPV emergence or VAPP. Participants in the sIPV arm of the trial developed neutralizing antibodies against poliovirus types 1, 2, and 3 with seroconversion rates of 98.0% against type 1 poliovirus, 94.8% against type 2, and 98.9% against type 3. Seroconversion rates were higher in the sIPV arm than in the IPV arm against all three types, significantly so against types 1 and 2. Participants in the IPV arm developed neutralizing antibodies against poliovirus types 1, 2, and 3 with seroconversion rates of 94.1% against type 1, 84.0% against type 2, and 97.7% against type 3.

 

“Sinovac’s sIPV carries higher immunogenicity with a lower biosafety risk, and demonstrates both long-term affordability and accessibility in comparison to conventional IPV, which is still inaccessible to many parts of the world, particularly in middle- and low-income countries. If approved, Sinovac’s sIPV can contribute to the fight for polio eradication in developing countries and the progress towards a polio-free world,” said Weidong Yin, Chairman, President and CEO. “We are very pleased with the sIPV clinical trial results and are grateful to the participants, their caregivers, and the staff of Guanyun and Pizhou centers for Disease Control and Prevention. Sinovac’s sIPV demonstrated superior results to those of IPV and we look forward to continuing the development of this critical vaccination and discussing these results with agencies worldwide.”

 

This study was a randomized controlled, double-blinded, noninferiority trial investigating the immunogenicity and safety of Sinovac’s sIPV. The study enrolled 1200 healthy infants ages 60-90 days that were randomly assigned at a ratio of 1:1 to receive 3 doses of either sIPV or IPV at days 0, 30, and 60. The safety of the vaccine was assessed for 30 days after each injection. The study was conducted in Pizhou City and Guanyun County in Jiangsu Province, China, from August 2017 to January 2018.
