Pfizer Receives European Approval for New Multi-Dose Vial Presentation of Prevenar 13®

Pfizer Inc. (NYSE:PFE) announced today that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) approved a new four-dose, multi-dose vial (MDV) presentation of Prevenar 13^®* (pneumococcal polysaccharide conjugate vaccine [13 – valent, adsorbed]). This new MDV presentation was developed to help maximize efficiency for health care workers by helping to significantly reduce storage requirements and shipping costs in communities with health systems that are still developing.

The MDV presentation of Prevenar 13^® offers significant benefits to developing countries, including a 75 percent reduction in:

• Temperature-controlled supply chain requirements,
• United Nations International Children’s Education Fund (UNICEF) shipping costs, and
• Storage requirements at the national, regional, district, and community levels.

“Prevenar 13^® is the first approved pneumococcal conjugate vaccine available in a preserved multi-dose vial presentation,” said Luis Jodar, Ph.D., global vice president, Vaccines, Pfizer Global Medicines Development Group and Medical/Scientific Affairs. “With this new presentation, a box that once carried enough vaccine to help protect 50 infants and children will potentially vaccinate 200, helping to ensure Prevenar 13^® is accessible in the most remote regions of the world where the greatest burden of invasive pneumococcal disease lies.”

Pfizer plans to submit its Prevenar 13^® MDV presentation to the World Health Organization (WHO) for prequalification, which, if and when approved, will allow for the global use of this new presentation of Prevenar 13^® by United Nations agencies and countries worldwide that require WHO prequalification. If and when prequalified, the MDV presentation is expected to be introduced under the Advance Market Commitment program in early 2017, for shipment to countries covered by Gavi, the Vaccine Alliance (Gavi). This presentation will be available at a lower price of $3.10 per dose.

“Prevenar 13^® formulated in multi-dose vials was studied in collaboration with the Medical Research Council Unit, The Gambia,” said William Gruber, M.D., Senior Vice President Vaccine Clinical Research and Development. “This multi-dose presentation of Prevenar 13^® demonstrated a favorable safety profile and immune responses to help protect children from invasive pneumococcal disease due to serotypes contained in the vaccine.¹”

Pfizer Vaccines in the Developing World

Accelerating the availability of potentially life-saving vaccines around the world is a key component of Pfizer’s commitment to making true inroads toward global health care access. Through its participation in international public-private programs, Pfizer provided its 13-valent pneumococcal conjugate vaccine, Prevenar 13^®, to infants and young children in the developing world to help protect against invasive pneumococcal disease. Since 2010, more than 40 low- and lower middle-income countries have launched pneumococcal immunization programs with Prevenar 13^®, via the Advance Market Commitment, an innovative program by Gavi, the Vaccine Alliance.² With continued investment in research and development, Pfizer has helped meet the challenges of the developing world by providing innovative manufacturing, storage, inventory management, and supply chain solutions. Pfizer also continues to develop and deliver educational materials to aid health care workers in the field and conducts surveillance studies to understand the impact of pneumococcal immunization programs on reducing the burden of disease.
