The Medicines Patent Pool (MPP) is a United Nations-backed public health organisation working to increase access to, and facilitate the development of, life-saving medicines for low- and middle-income countries. Through its innovative business model, MPP partners with civil society, governments, international organisations, industry, patient groups, and other stakeholders, to prioritise and license needed medicines and pool intellectual property to encourage generic manufacture and the development of new formulations. To date, MPP has signed agreements with 13 patent holders for 13 HIV antiretrovirals, one HIV technology platform, three hepatitis C direct-acting antivirals, a tuberculosis treatment, two long-acting technologies, two experimental oral antiviral treatments for COVID-19 and a COVID-19 serological antibody diagnostic test. MPP was founded by Unitaid, which continues to be MPP’s main funder. MPP’s work on access to essential medicines is also funded by the Swiss Agency for Development and Cooperation (SDC). MPP’s activities in COVID-19 are undertaken with the financial support of the Japanese Government, the French Ministry for Europe and Foreign Affairs, and SDC.
