In September 2021, the Medicines Patent Pool (MPP) announced a licence agreement with Tandem Nano Ltd. for University of Liverpool’s Unitaid-funded project LONGEVITY long-acting technologies, which, if proven safe and effective could help achieve optimal dosing regimens for malaria chemoprophylaxis, tuberculosis prevention, and hepatitis C cure.

The agreement allows sublicensees worldwide to develop finished products anywhere in the world, and to sell or distribute the resulting medicines for administration to patients in all low- and middle-income countries, on a royalty-free basis.
