On July 24, 2014, the Medicines Patent Pool announced welcome modifications and expansions of their licensing agreement with Gilead. Among the significant changes were the addition of a new drug, tenofovir alafenamide (TAF), formerly known as GS-7340. TAF is a nucleotide reverse transcriptase inhibitor, and a prodrug of tenofovir. TAF is considered to have similar antiretroviral efficacy to tenofovir disoproxil fumarate (TDF), the drug it may replace in use, but can be administered with smaller doses and with less adverse effect on kidneys and bones.

The first of these applications is dated October 21, 2011.
