BEIJING, Jan. 31, 2011 /PRNewswire-Asia/ -- Sinovac Biotech Ltd. (Nasdaq:SVA - News), a leading provider of biopharmaceutical products in China, announced today the submission of the applications to commence human clinical trials for its 23-valent and 24-valent pneumococcal polysaccharides vaccines to the Chinese State Food Drug Administration (SFDA) on January 31, 2011. The preclinical studies were completed and showed good safety and efficacy profile in animal models.
Sinovac independently developed the pneumococcal polysaccharides vaccine (PPV) and will retain full commercialization rights to the vaccine upon approval. The supplied quantity of PPV was doubled in China over the past three years，demonstrating the consistent increasing market demand. And the gap between demand and supply in Chinese market still exists. PPV remains relatively expensive in China due to the limited available products. The target population of PPV is children over 2 years old and adults in all age groups, especially the elderly over 65 years old.
The current available 23-valent PPV have shown good protection effects after launching into the market. But due to the different epidemic characteristics of pneumococcal diseases in China, we also developed the 24-valent PPV to cover one more serotype of pneumococcus, which is one of the top three most prevalent pneumococcus bacteria in China, and therefore has the potential to provide more extensive vaccine protection to the Chinese population.
Dr. Weidong Yin, Chairman & CEO, commented, "PPV is the first bacterial vaccine for which the Company has submitted the clinical trial application to the SFDA, representing our expansion of our R&D capabilities to include both bacterial and virus vaccines. The establishment of our bacterial vaccine development platform will accelerate the R&D for the pneumococcal conjugate vaccine and other types of bacterial vaccines in our pipeline, such as the HIB and meningitis vaccines. We consistently advance our R&D strategy to provide a greater number of high quality vaccine products aimed at preventing diseases in children and adults around the world."
About Pneumococcal Diseases
Pneumococcal diseases are a major public health problem all over the world. The etiological agent, Streptococcus pneumoniae (the pneumococcus) is surrounded by a polysaccharide capsule. Differences in the composition of this capsule permit serological differentiation between about 90 capsular types, some of which are frequently associated with pneumococcal disease, others rarely. Invasive pneumococcal infections include pneumonia, meningitis and febrile bacteremia; among the common non-invasive manifestations are otitis media, sinusitis and bronchitis. At least 1 million children die of pneumococcal disease every year, most of these being young children in developing countries. In the developed world, elderly persons carry the major disease burden. Conditions associated with increased risk of serious pneumococcal disease include HIV infection, sickle-cell anemia and a variety of chronic organ failures. Vaccination is the only available tool to prevent pneumococcal disease. The recent development of widespread microbial resistance to essential antibiotics underlines the urgent need for more efficient pneumococcal vaccines.
About PPV:
Pneumococcal polysaccharide vaccine (PPV), is a vaccine used to prevent Streptococcus pneumoniae (pneumococcus) infections such as pneumonia and septicaemia. In the United States, PPV is recommended for adults 65 years of age or older, adults with serious long-term health problems, smokers, and children older than 2 years with serious long-term health problems. The World Health Organization recommendations are similar. The safety of the current polysaccharide vaccines in older children and non-pregnant adults is well documented.
Sinovac's 23-valent PPV contains 23 different purified capsular polysaccharides prepared from the most prevalent and invasive strains of Streptococcus Pneumoniae, including serotypes 1, 2, 3, 4, 5, 6B, 7F, 8, 9N, 9V, 10A, 11A, 12F, 14, 15B, 17F, 18C, 19A, 19F, 20, 22F, 23F and 33F.
24-valent PPV contains 24 different purified capsular polysaccharides prepared from the most prevalent and invasive strains of Streptococcus Pneumoniae, including serotypes 1, 2, 3, 4, 5, 6A , 6B, 7F, 8, 9N, 9V, 10A, 11A, 12F, 14, 15B, 17F, 18C, 19A, 19F, 20, 22F, 23F and 33F.
