That is actually not much better than tenofovir vs tenofovir disoproxil fumarate, the actual substance in Viread. It is 50 times more potent than tenofovir.
It is all this improper simplification of callling viread tenofovir.
Tenovovir, if it would be given orally, would have no effect on HBV.
TEnofovir if given intravenously or sc would still have almost no effect on HBV in the liver. the substance has a high negative charge and cannot easlily penetrate cell membranes.
Bazinet and colleagues[17] conducted a randomized, controlled trial assessing the safety and efficacy of REP 2139 and a REP 2139 derivative with improved clearance (REP 2165) infused once a week in combination with tenofovir disoproxil fumarate and pegylated interferon alpha-2a in treatment-naive patients with chronic HBeAg-negative infection. This triple-combination therapy was well tolerated in all patients, and no infusion reactions were observed with either NAP.

GILD) files its New Drug Application (NDA) with the FDA seeking clearance of tenofovir alafenamide (TAF) 25 mg for the treatment of adults with chronic HBV infection. The company is transitioning its product line to TAF from TDF (tenofovir disoproxil fumarate) because it is just as effective at a dose less that one tenth that of TDF and is less stressful on the bones and kidneys.
The company intends to file its TAF Marketing Authorization Application (MAA) in Europe this quarter.

tenofovir disoproxil fumarate) is a prodrug of tenofovir. The 'disoproxil' is a side chain attached to the active component 'tenofovir'. Inside our body, this side chain gets cleaved off by an enzyme to release the active tenofovir. AGX-1009 has a different side chain attached to the active component 'tenofovir'. It may show higher potency and/or lower toxicity compared to Viread because of this different side chain (At least that's what Agenix is hoping for).

My doctor let me have Viread. I checked online at pharmacy checker. Tenofovir Disoproxil Fumarate Tablet and Viread Tablet, are they the same in treatment wise? I went to CVS store, it cost 1000 USD to 30/300mg for Viread Tablet. is it too expensive? The staff there told me generic tablet is not available. But why I see it online as I said earlier?
What happens if I take brand and then switch to generic like a year later? Will the generic medicine do the same?
Thank you.

Are there any online site where i can buy tenvir (tenofovir disoproxil fumarate) without prescription from the doctor? And 100% sure it will be delivered to your door?
The first portion of the ACHIEVE trial is a Phase 2a placebo-controlled, sequential-cohort, double-blind trial to evaluate increasing doses of SB 9200 as monotherapy for 12 weeks followed by tenofovir disoproxil fumarate (marketed by Gilead Sciences, Inc. as Viread®) 300 mg for an additional 12 weeks.
com, I see that branded Tenofovir Disoproxil Fumarate (Viread) costs $18.76 per pill for 300mg or about $570 per month if taking 30 pills. Entecavir (Baraclude), on the other hand, is even more expensive at $21.63 per pill (for 1mg) or $650 per month. Does Part D cover most of the cost for the two?
Or are you better off getting the generic for Tenofovir (is this Tenvir?), which seems to be significantly cheaper at $3.18 per pill (for 300mg) or $95 per month.

The REP 401 protocol (NCT02565719) is a randomized, controlled trial assessing the safety and efficacy of its first in class HBsAg release inhibitor, REP 2139 and a REP 2139 derivative with improved plasma and tissue clearance (REP 2165) in combination with tenofovir disoproxil fumarate (TDF) and pegylated interferon alpha-2a (peg-IFN) in treatment naïve patients with chronic HBeAg negative HBV infection.

Until April 2013, 137 patients (M/F: 102/35, mean age: 58±16 years) who started therapy with TDF 300mg daily between 2008 and 2011 have been included. TDF has been given for a mean of 32±15 months. Of the 137 patients, 69 were naive to NAs (Group A), while 68 had been exposed to other NAs (lamivudine resistance: 59, telbivudine resistance: 6, other: 3) (Group B). TDF was given as monotherapy in group A and in combination with lamivudine, at least during the initial period, in group B patients.
