Sofosbuvir has been studied extensively in clinical trials. In these studies, the side effects that occurred in a group of people taking sofosbuvir plus ribavirin (and sometimes peginterferon alfa) were documented and then compared to the side effects that occurred in a similar group of people given a placebo (a "sugar pill" with no active ingredients).

As reported at the 2011 AASLD Liver. Meeting, that regimen cured 100 of these patients. The ELECTRON researchers then looked at genotype 1 patients, both treatment-naive and null responders to previous interferon-based therapy.A multicenter retrospective study was performed to determine the efficacy and tolerability of a 12-week regimen of SIM/SOF with or without ribavirin (RBV) in 56 consecutive liver transplant recipients in 2014; 79 of patients had genotype 1a, 14 had cirrhosis, and 73 were treatment experienced.Two people ( experienced serious adverse events and one person (4) stopped treatment for this reason. The most common side-effects were anaemia (20 depression ( and headache (4). About 44 experienced grade 3 laboratory abnormalities including anaemia.SIM/SOF appears to have a niche as the only 12-week RBV-free treatment regimen currently recommended by guidelines for compensated transplant recipients. However, 12 weeks may not be the optimal duration of therapy for those with detectable virus at week 4 or possibly for those with cirrhosis.The investigators then asked whether adding a second direct-acting agent the NS5A replication complex inhibitor ledipasvir could increase cure rates for people with HCV genotype 1. Studies to date have shown that drugs in this class are highly potent and well tolerated.Direct-acting antiviral agents that target different steps of the hepatitis C virus lifecycle have ushered in a new era of treatment, but many patients and clinicians are awaiting all-oral therapy that avoids interferon and its difficult side-effects.Original Article.

Nezam Afdhal, M.D. Stefan Zeuzem, M.D. Paul Kwo, M.D. Mario Chojkier, M.D.Sustained virological response at 12 weeks (SVR12) was 88 by intention to treat analysis (95 confidence interval, 84-90). Four patients relapsed, but no on-treatment virological failures occurred. The Q80K polymorphism did not impact SVR12, but there was a trend toward decreased sustained virological response with advanced fibrosis (P 0.1.8Surgery, Division of Transplantation, University of Kentucky, Lexington, KY. 9Healthcare Transplant Center, University of Kentucky, Lexington, KY. 10Biochemistry and Molecular Genetics, University of Louisville, Louisville, KY.

Most combinations are mainly active against genotype 1. Sofosbuvir and GS-5816 from Gilead and daclatasvir by BMS have activity against the broadest range of genotypes. High SVR12 rates from combinations by other manufacturers may make treating G1 and 4 a more competitive market given the importance of drug pricing in access to treatment.
Replikóny HCV so zníženou citlivosťou voči sofosbuviru boli vybraté v bunkovej kultúre pre viacero genotypov vrátane 1b, 2a, 2b, 3a, 4a, 5a a 6a. Znížená citlivosť voči sofosbuviru bola spojená s primárnou substitúciou S282T v NS5B u všetkých skúmaných replikónových genotypov. Cielená mutagenéza substitúcie S282T v replikónoch 8 genotypov viedla k 2- až 18-násobnému zníženiu citlivosti voči sofosbuviru a znížila schopnosť vírusovej replikácie o 89 % až 99 % v porovnaní s príslušným divokým typom. V biochemických testoch vykazovala rekombinantná polymeráza NS5B genotypov 1b, 2a, 3a a 4a exprimujúca substitúciu S282T zníženú citlivosť voči GS-461203 v porovnaní s príslušnými divokými typmi.

Patients included in an international compassionate use programme for treatment with sofosbuvir and daclatasvir ± ribavirin for 24 weeks were prospectively studied. Serum hepatitis C virus RNA was measured at treatment weeks 4, 12, and 24 and during follow-up at weeks 4, 8, and 12.

So we wait, with Dec 9 being the very latest date and Sept 9 or Oct 9 being the same window of time that Sofosbuvir had. Hopefully the FDA will see the need to give Priority review based on the demand that an all oral treatment that has showed is needed. This of course assumes that Gilead requested priority review on the combo.�
Ledipasvir and sofosbuvir is not approved for use by anyone younger than 18 years old.
The bifurcated study broke out one group of 10 people with liver fibrosis. Fibrosis is part of the scarring process and represents the liver's response to injury.They received sofosbuvir and ribavirin. After 12 weeks of therapy, HCV was no longer present in all volunteers who completed therapy (nine out of 10).

But the drug's high price tag has stirred controversy. Senators Ron Wyden (D-Ore) and Charles Grassley (R-Iowa) have asked maker Gilead Sciences Inc. to justify the cost of Sovaldi. According to AP . 2011 filings with federal market regulators by Pharmasset, the company that originally developed Sovaldi, estimated the cost of a course of treatment at $36,000. Gilead later went on to acquire Pharmasset.
Sofosbuvir: A novel treatment option for chronic hepatitis C infection
June 28 2016 FDA Approved Gilead's Epclusa® (Sofosbuvir/Velpatasvir) to treat Genotype 1-6 Silver Spring, Maryland–(ENEWSPF)–June 28, 2016. The U.S. Food and Drug Administration approved Epclusa to treat adult patients with chronic hepatitis C virus (HCV) both with and without cirrhosis (advanced liver disease). For patients with moderate to severe cirrhosis (decompensated cirrhosis), Epclusa is approved for use in combination with the drug ribavirin. Epclusa is a fixed-dose combination tablet containing sofosbuvir, a drug approved in 2013, and velpatasvir, a new drug, and is the first to treat all six major forms of HCV.

My hubs has HCV and is a transplant patient, did 84 weeks of Interferon/Ribavirin and relapsed within weeks. He is an excellent candidate for the Sofosbuvir, with Interferon/Ribavirin…we already know what that will cost us—holy cow, another $50K for the sofosbuvir? Well, that’s life. Already out over $150K for the TP and tx post TP. Getting tired of this! But looking fwd to some hope with the sofosbuvir, if he can get it.

Cardiac disorders: Serious symptomatic bradycardia has been reported in patients taking amiodarone who initiate treatment with sofosbuvir in combination with another HCV direct-acting antiviral, including daclatasvir
La più alta dose documentata di sofosbuvir è stata una singola dose sovraterapeutica di 1.200 mg, somministrata a 59 soggetti sani. In questo studio non sono stati osservati effetti avversi a tale livello di dose e le reazioni avverse sono state simili per frequenza e severità a quelle segnalate nei gruppi di trattamento con placebo e con sofosbuvir 400 mg. Gli effetti di dosi superiori non sono noti.
The hepatitis C market has broken many records. With a list price of $84,000 — or $1,000 per pill — Sovaldi made Gilead billions, while also triggering debates about pharmaceutical pricing. A year later, Harvoni clocked in with a price tag of $94,500. As with most drugs, discounts were available for both, but the sticker-shock was still very real.
