NEW YORK, January 30, 2023 – Pfizer Inc. (NYSE: PFE) and the International Trachoma Initiative (ITI), a program of the independent nonprofit Task Force for Global Health, today announced donation of the one billionth Zithromax® (azithromycin) dose as part of the World Health Organization’s (WHO) recommended S.A.F.E. strategy to help prevent and treat trachoma. 

Donation of the one billionth dose builds on Pfizer’s June 2022 commitment to extend its antibiotic donation program through 2030, helping to enable 18 countries to continue trachoma elimination programs in 2023 and beyond. The WHO’s Neglected Tropical Diseases Roadmap has set a global elimination goal of 2030, which has already been achieved in 15 countries.

“Pfizer’s donation of one billion doses of Zithromax has been instrumental in the success of the global trachoma program and demonstrates to the world that elimination of this debilitating disease is possible,” said Jason Carter, Chairman, Board of Trustees, The Carter Center. “The Carter Center has been a proud partner in the trachoma elimination journey, which is core to our commitment to expanding simple health interventions that have a life-changing impact.”

This milestone marks a significant achievement and was made possible by decades-long partnerships to eliminate trachoma – the leading infectious cause of blindness globally. Together, trachoma elimination efforts around the world have successfully reduced the trachoma burden by more than 90 percent since 2002,¹ with an estimated 217.9 million people now believed to live free from the risk of trachoma according to ITI.²

“Through country leadership and the joint efforts of countless partners from around the world, millions of people are no longer at risk of this debilitating disease,” said Dr. Paul Emerson, Director, ITI. “Together, we have greatly reduced the risk of trachoma – including in the hardest-to-reach communities – and now we have a once-in-a-lifetime opportunity to build on this momentum and finally eliminate trachoma as a public health challenge.”

“Everyone, no matter where they live, should have access to life-saving medicines. That is why, for more than two decades, Pfizer has proudly joined researchers, global health partners and dozens of governments in efforts to eliminate trachoma,” said Caroline Roan, Senior Vice President, Global Health & Social Impact, Pfizer. “We celebrate donation of the one billionth Zithromax dose as a collective accomplishment with the global health community and an important step toward closing the health equity gap.”

Both a cause and a consequence of poverty, trachoma remains a public health threat for 125 million people living in hyperendemic areas of Africa, Latin America, Asia, Australia and the Middle East. An estimated 1.9 million people suffer visual impairment because of infection, and women are up to four times more likely to be blinded by trachoma than men.³ Zithromax is not approved in the United States or European Union to treat trachoma.Trachoma is a neglected tropical disease (NTD) caused by the bacterium Chlamydia trachomatis. After repeated infections, the disease scars the interior of the eyelid and causes it to turn inward (trichiasis), leading to great pain, corneal ulcers, and irreversible blindness if not treated by antibiotics or a simple surgical procedure.

Important Safety Information for Zithromax® (azithromycin)

Contraindications:

• Known hypersensitivity to azithromycin, erythromycin, any macrolide, or ketolide drug.
• History of cholestatic jaundice/hepatic dysfunction associated with prior use of azithromycin. 

Warnings and Precautions:

• Serious allergic reactions, including angioedema, anaphylaxis, and dermatologic reactions including Acute Generalized Exanthematous Pustulosis (AGEP), Stevens-Johnson Syndrome, and toxic epidermal necrolysis, have been reported rarely in patients on azithromycin therapy. Discontinue ZITHROMAX and initiate appropriate therapy if reaction occurs. 
• Abnormal liver function, hepatitis, cholestatic jaundice, hepatic necrosis, and hepatic failure have been reported, some of which have resulted in death. Discontinue azithromycin immediately if signs and symptoms of hepatitis occur. Discontinue azithromycin immediately if signs and symptoms of hepatitis occur.
• Following the use of azithromycin in neonates (treatment up to 42 days of life), Infantile Hypertrophic Pyloric Stenosis has been reported. Direct parents and caregivers to contact their physician if vomiting or irritability with feeding occurs. 
• Prolongation of QT interval and cases of torsades de pointes have been reported. This risk which can be fatal should be considered in patients with certain cardiovascular disorders including known QT prolongation or history of torsades de pointes, those with proarrhythmic conditions, and with other drugs that prolong the QT interval. Elderly patients may be more susceptible to development of torsades de pointes arrhythmias.
• Clostridium difficile-Associated Diarrhea: Evaluate patients if diarrhea occurs. If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued.
• Exacerbations of symptoms of myasthenia gravis and new onset of myasthenic syndrome have been reported in patients receiving azithromycin therapy.
• Close monitoring for known side effects of azithromycin, such as liver enzyme abnormalities and hearing impairment, is warranted when given with Nelfinavir.
• Warfarin use with azithromycin may increase coagulation times; monitor prothrombin time.

Most common adverse reactions are diarrhea (5 to 14%), nausea (3 to 18%), abdominal 
pain (3 to 7%), or vomiting (2 to 7%).

ZITHROMAX is a macrolide antibacterial drug indicated for mild to moderate infections

To reduce the development of drug-resistant bacteria and maintain the effectiveness of ZITHROMAX (azithromycin) and other antibacterial drugs, ZITHROMAX (azithromycin) should be used only to treat infections that are proven or strongly suspected to be caused by susceptible bacteria.

Safety and effectiveness in the treatment of patients under 6 months of age have not been established.
