Drug Names(s): tenofovir disoproxil fumarate, Tenofovir DF, TDF, GSK548470, GSK-4331, Tenozet
Description: Viread (tenofovir disoproxil fumarate) is a nucleoside analog of adenosine monophosphate. It requires initial diester hydrolysis for conversion to tenofovir diphosphate, an obligate chain terminator. Tenofovir diphosphate inhibits the activity of HIV-1 reverse transcriptase and HBV polymerase by competing with the natural substrate deoxyadenosine 5'-triphosphate and, after incorporation into DNA, by DNA chain termination. Viread is a weak inhibitor of mammalian DNA polymerase a, b, and mitochondrial DNA polymerase g.
The oral powder formulation of Viread uses Aptalis's Microcaps taste-masking technology. Gilead will be responsible for the product commercialization, while Aptalis will manufacture and supply the oral powder to Gilead.
Gilead and Japan Tobacco

Under the terms of the agreement, Gilead will receive an up-front fee and is entitled to receive additional cash payments upon achievement of certain milestones. JT also will make payments to Gilead based on product sales. JT will submit applications for Viread and Emtriva to Japanese regulatory authorities in the near future.
