GSK Receives CHMP Positive Opinion for Synflorix Pneumococcal Vaccine Four-Dose Vial

Jun 27, 2017 1:30 PM ET

June 27, 2017 /3BL Media/ - GSK announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has issued a positive opinion for a new four-dose vial presentation of its Synflorix pneumococcal vaccine. The approval is the first step in the process to deliver the new vaccine presentation through Gavi, the Vaccine Alliance, in developing countries.

Developed specifically to address the cold-chain and storage challenges faced in some areas of the world, the Synflorix four-dose vial has a cold-chain volume of 2.4cm3 per dose, 50 percent lower than the existing two-dose vial presentation, making it the lowest volume for any pneumococcal conjugate vaccine. This reduces the physical space required for storage in countries where cold-chain delivery can be challenging, and adequate storage facilities limited. Clinics and healthcare workers will be able to vaccinate more children per vial compared to the existing Synflorix two-dose vial presentation, and the new formulation of the Synflorix four-dose vial allows usage across a longer period of time after opening to 28 days, compared to six hours for the two-dose vial.

Thomas Breuer, Chief Medical Officer, GSK Vaccines said, “Synflorix has already had an enormous impact since it was launched, helping to protect against pneumonia – the world’s leading infectious killer of children under the age of five. Through this new presentation we hope to make it easier for more healthcare professionals in the most challenging areas of the world to turn our vaccines into life-saving vaccinations.”

More than 415 million doses of Synflorix have been distributed worldwide since 2009, helping to protect more than 100 million children. [1] GSK was one of the first companies to sign an agreement with Gavi, the Vaccine Alliance, and since 2010, has delivered more than 250 million doses of Synflorix to developing countries, including countries with large annual birth cohorts.1 As part of this ongoing commitment, GSK has agreed to make 720 million doses of Synflorix available by the mid-2020s to help protect children worldwide.

Following EMA approval, GSK will submit the new four-dose vial presentation to WHO for prequalification. Depending on WHO prequalification and local regulatory approvals, GSK expects to start supply of the new presentation to Gavi-supported countries in 2018.

About pneumococcal disease

Pneumococcal disease refers to infections caused by the bacterium Streptococcus pneumoniae, which can result in severe, and sometimes fatal, invasive disease, such as meningitis, sepsis and bacteraemic pneumonia. More common non-invasive manifestations of pneumococcal disease include sinusitis and AOM, an inflammatory infection of the middle ear, which affects millions of children worldwide.

An estimated 476,000 children under 5 years of age die from pneumococcal disease each year; this accounts for approximately 5% of all-cause mortality in children in this age group.[2]-[3][4]
