TENOFOVIR DISOPROXIL FUMARATE (TDF)
In July 2011, the Medicines Patent Pool (MPP) signed its first licence with a pharmaceutical company, Gilead Sciences, for tenofovir disoproxil fumarate (TDF), part of the World Health Organization (WHO)-preferred first-line treatment for adults. Additionally, patents on the combination of TDF/FTC and TDF/FTC with efavirenz (EFV), the WHO-recommended first-line regimen for adults, were added to the licence in 2015. The licence covers both treatment and Pre-Exposure Prophylaxis (PrEP), benefiting at least 112 countries.
In September 2017, the two parties amended the agreement to allow for an extension of the Territory for TDF to Belarus, Malaysia, Ukraine and Philippines. Together, the extended territory is home to 90.5% of people living with HIV in low- and middle-income countries.
In September 2019, the agreement was amended to allow for the inclusion of Azerbaijan to the territory of now 117 countries for BIC, COBI, TAF and TDF.
