About tenofovir alafenamide

Tenofovir alafenamide manufacturers include the originator Gilead Sciences and Indian generic producers that make TAF under licence for low- and middle-income countries. Tenofovir alafenamide (TAF) is a prodrug of tenofovir that delivers the drug into cells at a much lower dose than the older tenofovir disoproxil fumarate (TDF). It is used for chronic hepatitis B and, in combinations, for HIV treatment and prevention. Pharmaceutical companies can source TAF tablets, combination products and API through out-licensing, supply or technology transfer.

Tenofovir alafenamide key facts

Tenofovir alafenamide manufacturers and licensing history

Gilead developed TAF as a successor to tenofovir disoproxil fumarate (TDF). Because it delivers tenofovir more efficiently into cells, much lower doses are needed, with less effect on kidneys and bones. Genvoya was the first TAF-based product, approved in 2015, followed by Descovy, Odefsey, Vemlidy for hepatitis B in November 2016, and Biktarvy in 2018.

In September 2022, Gilead settled US patent litigation with Lupin, Apotex, Macleods, Hetero and Cipla. These companies received licences to sell generic Descovy and Vemlidy from 31 October 2031, and Odefsey from 31 January 2032, or earlier in certain circumstances. In January 2026, Cipla filed a 505(b)(2) application for emtricitabine/TAF referencing Descovy, and Gilead sued in February 2026.

For low- and middle-income countries, Gilead licensed TAF through the Medicines Patent Pool, and Indian companies produce generic TAF products for those markets. Buyers should confirm GMP status, a DMF and the territory covered by any licence.

Tenofovir alafenamide dosage forms and dossier types

TAF is approved as 25 mg tablets for hepatitis B and in several HIV combination tablets.

Tenofovir alafenamide regulatory and patent status

TAF was first approved in Genvoya in 2015 and as Vemlidy in November 2016. In the US, settlements allow generic Descovy and Vemlidy from 31 October 2031 and Odefsey from 31 January 2032. Gilead reports EU patent expiry in 2027. In low- and middle-income countries, generic TAF is available under the Medicines Patent Pool licence.

Tenofovir alafenamide mechanism of action and therapeutic use

TAF is converted inside cells to tenofovir diphosphate, which blocks the reverse transcriptase enzyme of HIV and the polymerase of hepatitis B virus. Compared with TDF, it reaches higher levels in cells with much lower levels in the blood. TAF is used alone for chronic hepatitis B and in combinations for HIV treatment and prevention.

Tenofovir alafenamide licensing and sourcing

TAF suppliers and licensing partners typically offer dossier out-licensing, finished-product supply or API supply. Buyers usually compare GMP status, WHO prequalification, licence territory and patent position. Current offers and supplier contacts are listed among the tenofovir alafenamide manufacturers on Pipelinepharma.
