SINOVAC Launches Major Clinical Trial for Innovative Vaccine

SINOVAC Launches Phase III Clinical Trial for HFMD Vaccine

SINOVAC Biotech Ltd. (NASDAQ: SVA), a leading biopharmaceutical company, has set its sights on significantly advancing healthcare for children by officially commencing a Phase III clinical trial for its bivalent vaccine candidate targeting hand, foot, and mouth disease (HFMD). This groundbreaking initiative aims to protect against HFMD caused by Enterovirus 71 (EV71) and Coxsackievirus 16 (CA16).

The Importance of HFMD Vaccines

HFMD is a viral disease that primarily affects young children, causing widespread concern among parents and healthcare providers. Despite its prevalence, there are currently no approved multivalent vaccines on the market worldwide. The initiation of this Phase III clinical trial represents a crucial step toward providing effective prevention against this common childhood illness.

The clinical trial has been meticulously designed as a multicenter, randomized, double-blind, controlled study. It aims to thoroughly evaluate the efficacy, safety, and immunogenicity of the bivalent vaccine candidate in infants and young children aged 6 to 71 months. Through this trial, SINOVAC hopes to establish solid data that demonstrates the vaccine's potential to offer robust protection.

Progress from Earlier Trials

Prior to this Phase III trial, SINOVAC successfully conducted a Phase I/II clinical trial in China, which showcased promising results regarding the vaccine's safety profile and immunogenic response. These results indicate that the vaccine is well-tolerated and can elicit a strong immune response, a crucial criterion for any vaccination.

Challenges remain in the pursuit of broad protection against HFMD, as multiple enteroviruses are implicated in the disease. SINOVAC recognizes the necessity for vaccines that provide comprehensive coverage due to the low cross-immunogenicity often exhibited by these viruses. Notably, the majority of clinical cases occur in children under five years old, compelling efforts to enhance the scope of protective measures available.

Future Pathways for HFMD Vaccination

In line with its commitment to innovative vaccine development, SINOVAC is also advancing the world's first tetravalent enterovirus inactivated vaccine. This vaccine has recently been approved for clinical trials, targeting EV71, CA16, CA10, and CA6, thus broadening the spectrum of viral protection for children.

To ensure the successful development and eventual market availability of both the bivalent and tetravalent vaccines, SINOVAC is collaborating closely with multiple partners, leveraging collective expertise in clinical research to expedite processes.

Commitment to Public Health

About SINOVAC, the company has built a reputation for prioritizing public health through effective vaccine development. With a comprehensive product portfolio that includes vaccines for COVID-19, hepatitis A, and various other infectious diseases, SINOVAC continues to explore innovative solutions to safeguard health.

Among its achievements, the COVID-19 vaccine, CoronaVac, has gained regulatory approvals across more than 60 countries, underscoring SINOVAC's role in addressing global health crises. Moreover, the company has demonstrated effectiveness in pediatric vaccines, such as the innovative EV71 vaccine and the Sabin-strain inactivated polio vaccine, which have also received WHO prequalification.

Moving forward, SINOVAC remains dedicated to developing cutting-edge biomedical products and exploring global opportunities for expansion. The company aims to leverage new technologies and research initiatives to continue its mission of saving lives and enhancing the quality of health across communities.
