 Simply put, Gilead would love to sell a 12 week course of DAA's followed by the course sent in to salvage the failure. That is a lot of cash.

Also it is designed to be the answer to the competitors failures.

 

Cha Ching!

Healio/Hepatitis C - FDA NEWS

Gilead submits NDA for investigational treatment of HCV - December 8, 2016

Gilead Sciences today filed a New Drug Application with the FDA for an investigational fixed-dose hepatitis C virus treatment.

The NDA is for a once-daily single tablet regimen containing 400 mg of sofosbuvir (Sovaldi, Gilead) and 100 mg each of velpatasvir and voxilaprevir (sof/vel/vox).

It would be the first once-daily single tablet regimen available as a salvage therapy for patients with HVC genotypes 1 through 6 infection who have failed prior treatment with direct-acting antiviral regimens including NS5A inhibitors, Gilead announced in a news release.

The data submitted in the NDA are from the phase 3 POLARIS-1 and POLARIS-4 studies and support the use of the regimen for 12 weeks in such patients without cirrhosis or with compensated cirrhosis, the company said.

"The remaining clinical need to treat HCV patients is a safe and effective cure for patients who have failed previous therapy with DAA regimens, including those with NS5A inhibitors," Norbert Bischofberger, PhD, executive vice president of research and development and chief scientific officer at Gilead, said in the release. "Sof/vel/vox has the potential to fill that need by offering single tablet dosing and high cure rates across all HCV genotypes for patients with and without cirrhosis, who have failed prior treatment with other highly effective regimens."

The sof/vel/vox fixed-dose combination was previously granted breakthrough therapy designation by the FDA for the treatment of patients with chronic HCV genotype 1 who previously failed an NS5A inhibitor-containing regimen.

 

Disclosures: Bischofberger works for Gilead.

Info from the recent Boston Meeting is starting to come out - this is "some" of the data about my 8 week trial. There will be more data forthcoming on this trial (and other trials), as well as many other topics covered in the Boston Meeting.

I could not find a way to copy and paste my trial results here, so here is the link, unfortunately I think you have to be registered and "log" into this site to read the thing - if so, I'll keep working on another way to get it showing.  smile C.

This link is about a new "typed" GT7, found in a Gilead trial. Not many GT7's ever seen thus far (I read somewhere).

Gilead was enrolling GT 1-6's into their trial. One gentleman they chose WAS typed GT2, so, he was entered into their trial designed for GT's 1-6. Turns out ... he is a GT7!! They had to plunk him mid-stream to be over in the "other" category, until it could be sussed that he was indeed not a GT2, but rather, a special 7! (fooled-ya!, I sure appear to be a 2, don't I, hee hee)  So, in the end, it's nice to know - (like a little surprize bonus) to find out (accidental-like) that sof/vel happens to work good on GT7's too!! Really pan!

Just another "graphic" portrayal of the stats on sof/vel/vox - easy to see at a glance how well cirrhotic GT3's did on only 8 weeks of sof/vel/vox. 

 

·         A Randomized Phase 3 Trial of Sofosbuvir/Velpatasvir/Voxilaprevir for 8 Weeks Compared to Sofosbuvir/Velpatasvir for 12 Weeks in DAA-Naïve Genotype 1-6 HCV-Infected Patients: The POLARIS-2 Study, by Ira M. Jacobson, et al. (LB-12)

 

Summary: This study compared treatment with sofosbuvir/velpatasvir/voxilaprevir for 8 weeks with treatment with sofosbuvir/velpatasvir (brandname Epclusa) for 12 weeks in patients with genotype 1-6 hepatitis C, who had or didn't have liver cirrhosis, and who hadn't previously been treated with a direct-acting antiviral agent (DAA). The most common side effect were headache, fatigue, diarrhea and nausea while taking SOF/VEL, and diarrhea and nausea while taking SOF/VEL/VOX.

Hey Tig!

You just finished posting the same thing, from dif source - great minds think alike eh! 

So, this one will be (mostly) just a duplication of which you already found. But it such a good topic tho, worthy knowing about the up and coming. And it IS the "latest" tidbit showing up on these drugs. biggrin

New Triple Combo Cures Most DAA-Experienced and Hard-to-Treat Hepatitis C Patients Without Ribavirin 

 Monday, 24 October 2016    Written by HIVandHepatitis.com

An investigational 3-drug coformulation from Gilead Sciences produced sustained virological response (SVR) in 95% to 98% of hard-to-treat hepatitis C patients in the Phase 3 POLARIS trials, including people who were previously treated with direct-acting antivirals and those with hepatitis C virus (HCV) genotype 3 and compensated cirrhosis, according to a recent company announcement. Gilead plans to request Food and Drug Administration approval of the new combination by the end of the year.

The advent of direct-acting antiviral agents (DAAs) that can be used in interferon-free regimens has revolutionized treatment for chronic hepatitis C. While the new drugs are far more effective and better tolerated than interferon-based therapy, there is still room for better options for some difficult-to-treat individuals including those who did not respond to prior DAA therapy and may have drug-resistant virus.

Some current standard-of-care DAA regimens require a longer duration or addition of ribavirin for hard-to-treat patients, which adds to the side effects, cost, and inconvenience of treatment.

The new single-tablet regimen combines drugs from 3 different classes -- the previously approved HCV polymerase inhibitor sofosbuvir and NS5A inhibitor velpatasvir, plus the investigational protease inhibitor voxilaprevir (formerly GS-9857). All agents are pangenotypic, meaning they are active against all HCV genotypes and can potentially be used on a global basis without the need for genotypic testing.

The Phase 3 POLARIS trials tested the triple combination taken for 8 or 12 weeks without ribavirin in more than 1000 patients.

In POLARIS-1, 96% of NS5A-experienced patients with HCV genotypes 1-6 were cured with 12 weeks of sofosbuvir/velpatasvir/voxilaprevir, compared with none of the placebo recipients. POLARIS-4 showed that the triple combination for 12 weeks worked better than a dual combination of sofosbuvir/velpatasvir for DAA-experienced patients who had not used NS5A inhibitors (SVR12 97% vs 90%).

POLARIS-3 demonstrated that 8 weeks of sofosbuvir/velpatasvir/voxilaprevir worked as well as 12 weeks of sofosbuvir/velpatasvir for patients with hard-to-treat genotype 3 and liver cirrhosis. However POLARIS-2, with a more diverse group of mostly non-cirrhotic DAA-naive patients with genotypes 1-6, did not reach the threshold for non-inferiority.

Below is an edited excerpt from a Gilead press release describing the studies and their findings in more detail.

 

Gilead Announces SVR12 Rates From Four Phase 3 Studies of a Once-Daily, Fixed-Dose Combination of Sofosbuvir, Velapatasvir and Voxilaprevir in Treatment-Naive and Treatment-Experienced Genotype 1-6 Chronic HCV-Infected Patients

- If Approved, SOF/VEL/VOX Would Be the First Once-Daily Single-Tablet Regimen Available for Salvage for Patients Who Have Failed Prior HCV Therapy with Oral Direct-Acting Antiviral Agent Regimens 

- U.S. NDA Planned for Q4 2016

Foster City, Calif. -- October 20, 2016 -- Gilead Sciences, Inc.(NASDAQ: GILD) today announced topline results from four international Phase 3 clinical studies (POLARIS-1, POLARIS-2, POLARIS-3, and POLARIS-4) evaluating an investigational, once-daily, fixed-dose combination of sofosbuvir (SOF), a nucleotide analog NS5B polymerase inhibitor; velpatasvir (VEL), a pangenotypic NS5A inhibitor; and voxilaprevir (VOX; GS-9857), an investigational pangenotypic NS3/4A protease inhibitor, for the treatment of genotype 1-6 chronic hepatitis C virus (HCV) infection.

In the POLARIS-1 and POLARIS-4 studies, 445 patients with genotype 1-6 HCV infection who were previously treated with direct-acting antiviral agents (DAAs) received 12 weeks of SOF/VEL/VOX. The POLARIS-1 study enrolled patients who failed prior treatment with an NS5A inhibitor. The POLARIS-4 study enrolled patients who failed prior treatment with a DAA that was not an NS5A inhibitor, most with either an NS5B inhibitor alone (73 percent) or an NS5B inhibitor and an NS3/4A protease inhibitor (25 percent).

In the POLARIS-2 and POLARIS-3 studies, 611 patients who were not previously treated with a DAA received 8 weeks of SOF/VEL/VOX. The POLARIS-2 study enrolled patients with genotype 1-6 HCV infection with or without compensated cirrhosis. The POLARIS-3 study enrolled patients with genotype 3 HCV infection, all of whom had compensated cirrhosis.

The primary endpoint for all studies was SVR12. The intent-to-treat SVR12 rates observed in the POLARIS studies are summarized in the following table. Complete results from all four studies will be presented at The Liver Meeting 2016 in Boston.

Patients treated with SOF/VEL/VOX for 12 or eight weeks had similar overall incidence of adverse events compared to placebo-treated or SOF/VEL-treated patients. The most common adverse events among patients who received SOF/VEL/VOX were headache, fatigue, diarrhea, and nausea. Among the 1,056 patients who received SOF/VEL/VOX in the four studies, one patient (less than one percent) receiving SOF/VEL/VOX for 12 weeks discontinued due to an adverse event.

"Despite recent advances that have provided high cure rates and simplified treatment for most HCV patients, those who have failed previous treatment with direct acting antivirals continue to represent an unmet medical need. The POLARIS study results demonstrate that combining three potent antivirals with different mechanisms of action and high barriers to resistance can provide high cure rates for patients who have failed other highly effective oral DAA regimens," said Norbert Bischofberger, PhD, Executive Vice President of Research and Development and Chief Scientific Officer at Gilead. "Based on these Phase 3 results, we plan to submit regulatory applications for SOF/VEL/VOX for the treatment of chronic HCV in the United States in the fourth quarter of 2016 and shortly thereafter in Europe."

About the POLARIS Studies

The POLARIS-1 study was a double-blind, placebo-controlled study in 415 genotype 1-6 NS5A inhibitor-experienced patients. The most common prior NS5A inhibitors were ledipasvir (55 percent) and daclatasvir (23 percent).

The open-label POLARIS-4 study evaluated the use of SOF/VEL/VOX or SOF/VEL for 12 weeks in 333 genotype 1-4 HCV-infected patients with prior DAA experience that did not include an NS5A inhibitor. Most patients (85 percent) had prior DAA experience with sofosbuvir.

The open-label POLARIS-2 study evaluated the use of SOF/VEL/VOX for eight weeks or SOF/VEL for 12 weeks in 941 genotype 1-6 DAA-naive HCV-infected patients, including 18 percent with cirrhosis and 23 percent who had previously failed treatment with an interferon-based regimen.

The open-label POLARIS-3 study randomized patients with genotype 3 HCV infection and cirrhosis to receive SOF/VEL/VOX daily for eight weeks or SOF/VEL for 12 weeks. Of the 219 patients treated, 31 percent had previously failed treatment with an interferon-based regimen.

The POLARIS-1, POLARIS-3, and POLARIS-4 studies met their respective pre-specified primary endpoints for the patients receiving SOF/VEL/VOX. The POLARIS-2 study did not meet its primary endpoint; with a pre-specified 5 percent margin, the SVR12 rate for patients receiving treatment with SOF/VEL/VOX for eight weeks was not statistically non-inferior to the SVR12 rate for patients receiving SOF/VEL for 12 weeks.

About SOF/VEL/VOX

The SOF/VEL/VOX fixed-dose combination is an investigational product and its safety and efficacy have not been established. It has been granted Breakthrough Therapy designation by the U.S. Food and Drug Administration for the treatment of chronic genotype 1 HCV patients who have previously failed an NS5A inhibitor-containing regimen.

Nice, that in North America, especially across the U.S.A. we see the blossoming - people finally getting Epclusa by prescription! Even in "slow poke" Canada, we have now seen a start, at least one lucky soul on site, who got her Epclusa by Canadian script! But, for others in other countries, the newer DAA treatments (never mind SOF/VEL) still remains far away, their best hope at receiving any "choice" or any "better" drug choice may come down to being lucky enough to find a trial! Here are the only SOF/VEL trials I've found around the world lately, for which Gilead may be "recruiting". (Just in case somebody, somewhere is looking for a SOF/VEL trial). Funny, there seem to be no further SOF/VEL/VOX trials tho. Just one trial which includes a Riba component. I will be looking forward to hearing more about VOX making it's debut, over Riba, as a triplet therapy with SOF/VEL.

More old stuff - on SOF/VEL/VOX:

Wish I knew how to change the title of this thread to just "SOF/VEL and SOF/VEL/VOX" info, as it has morphed from beyond where it started - we've gone from trials only (for difficult GT's like 3's), to now prescriptions of SOF/VEL starting to be made available for every GT! (Near regardless to cirrhosis, genotyping, or existing RAV identification!) And, SOF/VEL may soon be joined by VOX (NS3/4A) - for Gilead's triplet for just about any relapser as a rescue regime!

Geyawd! Another exhaustively complete one on sof/vel (I should say so! at 60 pages)! Near everything in one nutshell tho ...

http://www.gilead.ca/pdf/ca/Epclusa_pm_english.pdf

Hmmm - maybe this thread title should change, as it has morphed beyond just sof/vel trials for GT 3's, and is on to sof/vel and vox info applying to all GT's!

Hi Pablo,

thanks for the succinct summary. This woman is just too smart for me. I try to start reading, concentrating really hard, screwing my mouth into what I hope is an intelligently following along expression, nodding wisely periodically but then.... I realise for the last five minutes my eyes have been dutifully scanning the words but my brain has been thinking about feeding the dog or my itchy armpit.

Syd

ps. Love you Canuck and appreciate all the info you find for us. Xxxx

Great stuff Canuck.  I think it's safe to say that if one can get prescribed sof/vel/vox, especially so for 12 weeks (instead of 8), you have the best chance of SVR compared to another other regime regardless of your genotype, prior treatment status and cirrhosis level.

One of the earlier (phase 2) sof/vel/vox trials - comparing to sof/vel/vox to sof/vel/riba

When are they going to start using vox versus riba for a triple? We have relapaser's of other DAA's and folk with particularly well suited RAV's waiting!!

SOF/VEL/GS-9857: 400/100/100 mg FDC qd. Lawitz E, EASL 2016, Abs. PS021, J Hepatol 2016;64:S146. Design.TRILOGY-3 Study: SOF/VEL/GS-9857 RBV...
 
 
Even though this earlier trial result is now "old", as we wait for further data updates on phase 3 results's - note the "sides" - (Vox triple compared to the riba triple) - we see "less"/different adverse side effects, none of riba's blood dyscrasia's. Aside from adverse effects, just based on effectiveness of the sof/vel/vox triple alone (gleaned from other reports) I believe that vox as an added NS3/4A for a sof/vel triple is superior over riba in multiple/different and important ways.
 
Further (on Lawitz's data):
 

HIGH EFFICACY OF SOFOSBUVIR/VELPATASVIR PLUS GS-9857 IN PREVIOUSLY TREATED PATIENTS WITH HCV GENOTYPES 1 THROUGH 6

Dr Eric Lawitz presented results from 3 phase 2 trials that evaluated the combination of sofosbuvir, velpatasvir, and GS-9857 (VOX) in patients with previously treated HCV.1-8 Velpatasvir is an NS5A inhibitor, and GS-9857 is an NS3/4A inhibitor with a superior resistance profile compared with other NS3 protease inhibitors. All 3 DAAs have demonstrated efficacy against HCV genotypes 1 through 6. The single-center, open-label, phase 2 TRILOGY-3 trial enrolled patients with HCV genotype 1 infection previously treated for at least 6 weeks with a DAA.The study design designated enrollment of approximately 50% of patients with compensated cirrhosis. Patients were stratified based on cirrhosis status and prior treatment with NS5A inhibitors. Twenty-four patients received a single daily tablet of sofosbuvir (400 mg)/velpatasvir (100 mg), plus daily GS-9857 (100 mg) for 12 weeks. In 25 patients, this regimen was administered with the addition of weight-based ribavirin. The primary endpoint was SVR12.

Patients had a mean age of 54 years (range, 18-75 years), and approximately two-thirds were male. Approximately 86% of patients had the IL28B non-CC genotype. As planned, half of patients had cirrhosis. The mean level of HCV RNA was 6.3 log10 IU/mL (range, 5.2-7.1 log10 IU/mL). Eighty-eight percent of patients had HCV genotype 1a infection. Previous treatment included an NS5A inhibitor in 41%. Among these patients, 6% had received only the NS5A inhibitor, 14% had also received an NS3 inhibitor, and 20% had received prior treatment with an NS5A inhibitor, an NS5B inhibitor, and an NS3 inhibitor. Among patients who had not received an NS5A inhibitor, prior treatments included an NS3 inhibitor (31%), an NS5B inhibitor (16%), and both (12%).

The overall SVR12 rate was 98%. One patient in the ribavirin-containing arm experienced virologic failure at follow-up week 4. The patient who relapsed was a 61-year-old black man with cirrhosis, who had previously received treatment with ledipasvir/sofosbuvir for 24 weeks. He relapsed after discontinuation of therapy. Baseline analysis for the TRILOGY-3 study showed that this patient had NS5A resistance-associated variants (RAVs), but no NS3 or NS5B RAVs. After relapsing during the follow-up period, the patient was found to have 1 additional NS5A RAV and 4 new NS3 RAVs. In the entire study population, 36 patients (75%) had baseline RAVs. Fifteen percent had NS5A RAVs only, 29% had NS3 RAVs only, and 31% had multiple-class RAVs. Among the 36 patients with any baseline RAVs, 35 (97%) achieved SVR12 (Figure 4). All 12 of the patients who lacked baseline RAVs achieved SVR12.

AEs were common but generally mild-to-moderate in severity. AEs of any grade were reported in 11 patients (46%) in the ribavirin-free arm and in 15 patients (60%) in the ribavirin-containing arm. In the ribavirin-containing arm, there was a single grade 3 AE, consisting of rash that resolved upon discontinuation of ribavirin. There were no permanent treatment discontinuations or deaths during the study. One serious AE of pneumonia occurred in the ribavirin-free arm; however, this patient completed the 12 weeks of DAA treatment and achieved SVR12. Grade 3/4 laboratory abnormalities were more common in patients who received ribavirin (24% vs 4%). Hemoglobin levels of less than 10 g/dL were observed in 6 patients (24%) in the ribavirin arm vs none in the ribavirin-free arm. The most common AEs of any grade in the ribavirin arm were fatigue (36%), anemia (16%), and diarrhea (13%). These AEs did not occur in the ribavirin-free arm.

Dr Lawitz also presented results for treatment-experienced patients enrolled in 2 phase 2 trials that investigated treatment with sofosbuvir, velpatasvir, and GS-9857.10 Study GS-US-367-1168 included 197 patients with HCV genotype 1 infection; study GS-US-367-1169 included 128 patients with HCV genotype 2 to 6. Both trials included patients with or without cirrhosis, as well as patients who had received prior HCV treatment, including DAAs. Patients with HCV genotype 1 had received prior treatment with an NS5A inhibitor or at least 2 DAAs from different classes. Patients with genotypes 2 through 6 had received prior treatment with pegylated interferon plus ribavirin or any DAA. The 2 studies enrolled a total of 128 treatment-experienced patients, all of whom received 12 weeks of treatment with daily sofosbuvir (400 mg)/velpatasvir (100 mg) plus daily GS-9857 (100 mg).

The 128 patients had a mean age of 58 years (range, 37-77 years), 75% were male, and 82% were white. Approximately three-fourths of patients had the IL28B non-CC genotype, and 48% had cirrhosis. The mean HCV RNA level was 6.3 log10 IU/mL (range, 3.8-8.1 log10IU/mL). Patients had HCV genotypes 1 (49%), 2 (16%), 3 (27%), and 4 or 6 (7%). Prior DAA treatments included 1 DAA class in 28% and 2 or more DAA classes in 51%, and 27% of patients had received prior treatment with an NS5A inhibitor. Twenty-one percent of patients had received prior treatment with pegylated interferon plus ribavirin but no prior DAA treatment. Among the 66 patients (52%) with prior non-NS5A DAA treatment, 24% had received prior treatment with an NS5B inhibitor alone. Another 24% had received treatment with an NS5B inhibitor and an NS3 inhibitor. The remaining 4% of patients had received treatment with an NS3 inhibitor, an NS5B nucleotide polymerase inhibitor, and/or an NS5B nonnucleotide polymerase inhibitor. Among the 35 patients (27%) who had received prior treatment with an NS5A inhibitor, 11% had received prior treatment with an NS3 inhibitor and an NS5A inhibitor, with other combinations accounting for the remaining patients, including
1 patient who had failed all 4 classes
of DAAs.

At baseline, 77 patients (60%) had RAVs, and 76 of these patients (99%) achieved SVR12. The 1 patient who failed to achieve SVR12 was infected with HCV genotype 3 and relapsed at follow-up week 8. Among the 51 patients (40%) without baseline RAVs, 51 (100%) achieved SVR12. Among the 77 patients with baseline RAVs, 76 achieved SVR12 (99%; Figure 5). In the entire study group, SVR12 was reported in 100% of patients with HCV genotype 1, 2, 4, or 6 and in 97% of patients with HCV genotype 3. Subgroup analysis showed that the presence or absence of cirrhosis did not affect the likelihood of achieving SVR12. Similarly, prior treatment had no apparent impact on the likelihood of achieving SVR12. The single patient who experienced virologic failure had HCV genotype 3, was cirrhotic, had no prior NS5A exposure, and had been exposed to 1 class of DAA therapy prior to study enrollment.

Sixty-five percent of patients experienced an AE of any grade. Two patients (2%) experienced a grade 3 AE, and 2 patients (2%) experienced a serious AE. One patient (<1%) discontinued treatment due to an AE considered unrelated to study treatment, and 1 patient (<1%) died from a presumed sudden cardiac arrest 14 weeks after completing the study. Eleven patients (9%) had grade 3/4 laboratory abnormalities without clinical consequences. The most common AEs were headache (22%), diarrhea (19%), fatigue (20%), and nausea (14%).

Still not much data out there about that NS3/4A "VOX" yet (as far as it starting to be used along with sof/vel, versus just the folks getting it via trials), but, here is some more about it's "interactions": 

B. DRUG INTERACTIONS
 
1. DDI with Voxilaprevir (GS-9857)

 
SOF/Velpatasvir/Voxilaprevir (VOX) is a three-drug fixed dose DAA combination being evaluated in Phase 3 trials. In vitro, VOX is a substrate for CYP3A4, CYP2C8, the OATP uptake transporters and the efflux transporters P-gp and BCRP. VOX is also an inhibitor of P-gp and BCRP in vitro. Dr. Kirby presented drug interaction studies with VOX (Abstracts #O_24 and #O_25). Tables below show results of VEL as a victim and perpetrator in interactions. Results indicate VOX is very sensitive to hepatic inhibition of OATP transporters, so coadministration of VOX with potent OATP inhibitors is not recommended.
 
Inhibitors of CYP3A4, CYP2C8, and P-gp are likely okay with VOX. As with all HCV treatments, interactions with HMG-CoA reductase inhibitors (statins) must be considered with a potential need to change statins or use a reduced dose of the statin. It is likely based on these data that VOX will have problematic interactions with efavirenz and HIV protease inhibitors.

2 WEEK PCR's

A study, and then a doc's comment at bottom, reflecting on any importance attached to a 2 week PCRs data in older regime(s) study: (Another feather in the cap alluded to for the new world of sof/vel!)

Clinical value of on-treatment HCV RNA levels during different approved sofosbuvir-based antiviral regimens.

Maasoumy B., et al.
J Hepatology 2016 ; April 13 (Epub ahead of print)

Background & Aims : EASL guidelines recommend HCV-RNA measurements at specific time-points during sofosbuvir(SOF)-therapy. However, it remains unclear, how these results should be interpreted. We aimed to analyse whether on-treatment HCV-RNA levels predict relapse comparing the CobasAmpliPrep/CobasTaqMan v2.0 (CAP/CTM) and Abbott RealTime HCV (ART) assays.

Methods : Samples were collected from 298 patients(HCV-genotypes; GT1-5) at weeks(w) 0, 1, 2, 4, 8, 12, 16, 20 and 24 during SOF-based therapy at two University clinics and tested for HCV-RNA level by CAP/CTM and ART. Patients were treated with SOF/ribavirin(RBV) 12/24w (n=99), pegylated-interferon-alfa(Peg-IFN)/SOF/RBV 12w (n=51), SOF/simeprevir(SMV)±RBV 12w (n=69) or SOF/daclatasvir±RBV 12/24w (n=79).

Results : HCV-RNA levels during the first 4 weeks of SOF/RBV-therapy were significantly lower in GT3-patients who achieved SVR compared with those who relapsed. All GT3-patients with a week 2 result <45IU/ml by CAP/CTM achieved SVR but only 33% of those with >45IU/ml(p=0.0003). Similar results were documented with ART and 60IU/ml as cut-off (SVR:100% vs. 29%;p=0.0002). In contrast, HCV-RNA levels during early treatment phases were not significantly related to relapse in patients treated with other SOF-based regimens. Residual HCV-RNA was frequently detected by ART at later stages of therapy. However, SVR-rates remained high in these patients. At the end of SOF/SMV±RBV6 therapy HCV-RNA was detectable with ART in 20% of patients, of whom 92% achieved SVR.

Conclusions : HCV-RNA levels assessed at week 2 of SOF/RBV-therapy can predict relapse in GT3-patients. Detectable HCV-RNA results at later stages during SOF-based therapy may occur frequently with the more sensitive ART. However, this should not lead to treatment extension.

Expert's Commentary

The practical impact of this paper is not marginal. For years we have been using on- treatment viral kinetics to individualize IFN-based treatment duration for our chronic HCV infected patients. Now, with the use of Direct Antiviral Agents the meaning of this predictor can be considered insignificant. The only exception seems to be presented in this study identifying, in patients with genotype 3 infection a week 2 HCV RNA >45 IU/ml by Cobas Ampli Prep/CobaseTaqMan or >60 IU/ml by Abbott Real Time, as predictive of relapse. This result appears of immediate utility, although with the arrival of new and more potent combinations for treatment of genotype 3 patients, such as the combination of velpatasvir and sofosbuvir, the week 2 prediction can be expected to be less relevant. Interestingly, the study clarifies also the issue of a residual viremia at the end of treatment. Until now no systematic evaluation of this observed phenomenon was available. Detectable HCV RNA below the quantification threshold, at the end of the established treatment duration can be observed in up to 20% of patients receiving oral antivirals. According to the study results, we should not consider a residual viremia as predictive of relapse. As shown in this study, in 92% of subjects this residual HCV RNA was not followed by a relapse and should not generate attempts to extend treatment duration.

Yawn. Ho-hum. Here's some already stale "stock" talk ... still no new riveting new news on VOX!  Mildly interesting tho - SOF/VEL patent to 2032, as is the "guess" that VOX and VEL really were created "in-house", and that sof/vel is a good buy for countries 'cause they will save a bundle, because of no GT'ing required? And, just when is this triplet VOX "salvage" thing ever going to be rolled-out?

For hepatitis C

1. Sofosbuvir/velpatasvir (SOF/VEL)

This has a patent expiry of 2032 for both the US and EU.

I look at this as a breakthrough, first-in-class product that may be receiving insufficient attention from analysts. It has a PDUFA date of June 28. The cure rates even for genotypes that are notoriously difficult to treat, such as genotype 3, are impressive (95%).

In addition to being first-in-class, perhaps time will also show it to be best in class.

GILD's main speaker at the Merrill Lynch conference, EVP Paul Carter, volunteered that this is going to be a very important product for developing countries, most notably China. His comments indicated that GILD is hard at work getting SOF/VEL to the Chinese market ASAP.

The benefit of SOF/VEL is that once HCV is found to be chronically infecting a patient who will benefit from cure, nearly everyone can just take one pill a day for 12 weeks with a high chance of cure. This is going to be transformative for parts of the world with limited scientific and/or financial resources, as patients can be treated with no genotyping needed.

Also, within the developed world, certain important genotypes (mainly types 2 and 3) will be treated with SOF/VEL rather than (usually) Sovaldi and accompanying drug(s). Whether this replacement of Sovaldi by SOF/VEL will have much economic benefit to GILD is unclear.

However, maybe a marketing benefit could be bundling SOF/VEL with anything ranging from access, or preferred access as appropriate, to Harvoni and/or SOF/VEL for genotypes 1 and 4. It's these genotypes where the real competition with AbbVie's and Merck's (NYSE:MRK) products occurs. In return, a lower price on SOF/VEL could be offered.

In any case, the key with this combo is that it opens up vast numbers of patients globally to treatment with a GILD product.

Velpatasvir, the "VEL" in the combo's current name, was developed in-house at GILD to my knowledge.

 

2. SOF/VEL plus voxilaprevir (formerly GS-9857, voxilaprevir is a pan-genotypic protease inhibitor)

Mr. Carter went into the rationale for developing this product. He noted that protease inhibitors are prone to have additional side effects. He offered up the standard GILD points that safety and efficacy, not duration of treatment, is what the regulators care about, and more or less the only things they care about. So, GILD is thinking of this triplet as salvage therapy, for difficult cases, etc., but with potentially shorter treatment courses.

For those keeping score, I do not recall GILD acquiring GS-9857, but I could be wrong. For now I'm thinking of it as yet another anti-viral that has been discovered internally.

GT 3's and SOF/VEL trials - and, SOF/VEL/VOX, and Epclusa roll-out (for all GT's 1-6, and "relapse rescue").
Permalink  
 


From hepctip:

Epclusa (sofosbuvir / velpatasvir), the first hepatitis C treatment able to cure six types of the hep C virus with high success rates against all of the six types, has been approved for use in America for all of those six types!

The hep C treatment sofosbuvir / velpatasvir (American brand name Epclusa) was approved by the U.S. Food and Drug Administration (FDA) yesterday. It was approved for the treatment of adult patients with a chronic hepatitis C virus infection, genotype1, 2, 3, 4, 5, or 6. This approval means that it can be prescribed to those with or without liver cirrhosis and can be prescribed with or without the drug ribavirin (prescribed with ribavirin for patients with liver cirrhosis, Child-Pugh B or C).

Sofosbuvir / Velpatasvir (American Brand Name Epclusa)

Description: Sofosbuvir / velpatasvir is a short-course hep C interferon-free treatment that can be prescribed with or without ribavirin. It is a pill taken once a day.

It is the first once daily pill treatment for patients with hep C genotype 2 and 3, without the need for ribavirin.

Approved for in the States: Epclusa taken for 12 weeks was approved in patients without liver cirrhosis or with compensated liver cirrhosis (Child-Pugh A), and in combination with ribavirin (RBV) for patients with more serious  liver cirrhosis (Child-Pugh B or C).

Common Side Effects: The most common side effects of sofosbuvir / velpatasvir are headache and fatigue. However, If it is combined with ribavirin, patients may experience side effects from the ribavirin.

Sofosbuvir / Velpatasvir in Canada

Sofosbuvir / velpatasvir isn't approved for use in Canada yet.

Clinical Trial Results for Sofosbuvir / Velpatasvir

In Phase III clinical trials, the treatment's safety and effectiveness as a 12 week treatment was evaluated on 1,558 patients without liver cirrhosis or with mild cirrhosis. With or without ribavirin, it cured 95-99% of those patients. In trials, it also cured 94% of those with  moderate to severe liver cirrhosis.

 

"This drug regimen changes the standard of care in treating patients with HCV. We can now cure almost everyone with a very simple treatment," said Dr. Jordan Feld, a liver specialist at Toronto Western Hospital.

One thing I don't want is to get into is a political debate. That said, I will say that I wouldn't believe much of what you hear from politicians right now. It's an election year in the USA and if I've learned anything, a politician will promise you a trip to the Moon and end up giving you a ticket for a cab ride to the Dollar store. 

I think one option is in the easy access to certified generic medications. There are things that can be done and Big Pharma gets a lot of R&D subsidies and tax breaks from the US government. They have a right to profits, that's free market capitalism. I think there are limits to the obscene profits when, as we all know, people are sick and dying. We have a big can of worms in front of us and we have to find a way to open it in an orderly fashion. We have enough confusion and hurdles to care...

The goal is

Great post Canuck!

It's good to see that Epclusa is getting on the momentum program and $60,000 at least is going in the right direction.

Lisa

I am glad to see the drug companies being challenged and especially when some tax payer money helped fund them. I wonder how many other countries will not recognize Gilead's patent on their drugs. I realized they need to recoup their R&D money but selling  100 x more drugs at lower costs will still get them there and wipe of the disease.

Wendy,

Is that list available? Could you possibly post a link to it?

Have a great weekend everyone.

On a similar note, in our local news today there was an article on which drugs CVS and Express Scripts will not cover in 2017 and many of the HCV treatments were on there but it did list what they are replaced with and they listed many of the new protocols, which I was glad to see.

I was reading yesterday that Hilary Clinton has challenged drug companies over their prices, naming specifically Gilead and their Hep C drugs. Tax payers money help fund their research and they repay us with huge prices on top. These huge profits are stopping a universal cure for a disease that is now effectively is easy to treat and cure. I am pretty happy to hear this is now being targeted. I know there are many countries still not able to access these simple life saving drugs and we are effectively and there is no justification. Lets hope something is done about it now...

More about Epclusa (in Canada) for GT 1-6 - hmph, riba reccomendations! - what going to happen to that VOX they trialed?

Here is how Epclusa is meant to be used for different types of HCV-associated liver disease:

  • people who have chronic HCV infection without cirrhosis (severe scarring of the liver) or who have compensated (symptom-free) cirrhosis - one tablet taken once daily with or without food for 12 consecutive weeks
  • people who have chronic HCV infection and symptoms (decompensated) of cirrhosis - one tablet taken once daily with or without food for 12 consecutive weeks. The antiviral drug ribavirin must also be taken. Ribavirin is taken twice daily with food, also for 12 consecutive weeks.

Summary of important safety information

Before starting a new medication, always speak to your doctor, nurse and pharmacist about its potential interactions with other drugs (such as prescribed and over-the-counter medicines, supplements and herbs). These healthcare providers can tell you how to take Epclusa safely.

Here is some limited safety information:

  • The drug amiodarone is used to treat abnormal heart rhythm. Gilead does not recommend that people who are taking amiodarone also take Epclusa, as this can result in reduced heart rhythm (slower rate of heart beats; bradycardia). This can be dangerous. If patients taking amiodarone have no alternative to using Epclusa, Gilead recommends that doctors order cardiac monitoring in people who take these medicines together.
  • Epclusa contains velpatasvir. The HIV drug efavirenz (Sustiva, Stocrin and in Atripla) reduces the amount of velpatasvir in the blood. Therefore, efavirenz users should not take Epclusa.
  • The herb St. John's wort (or its active ingredients hypericin and hyperforin) should not be used with Epclusa, as it can lower levels of both sofosbuvir and velpatasvir.

 

Access to Epclusa - (only in Canada you say??) as usual ... every Province will be different!

After Health Canada licenses a drug, physicians can prescribe it but patients must pay for it themselves unless they have a private insurance plan that covers it. It may take weeks or months for such coverage to take effect after licensure. In the months ahead, Gilead Sciences and provincial and territorial formularies will be negotiating the price of Epclusa ...

... in Canada, provincial and territorial ministries of health heavily subsidize the cost of anti-HCV medications. Each ministry has a listing of drugs for which it is prepared to pay. These listings are called formularies. Formularies can also place restrictions on who can access the drugs they are covering.

... In the months ahead, Gilead Sciences and provincial and territorial formularies will be negotiating the price of Epclusa. Your pharmacist, nurse or doctor can tell you when Epclusa is listed on your region's formulary.

The wholesale cost of Epclusa in Canada is about $60,000 for a 12-week course of therapy. Pharmacies in Canada can anticipate being able to order Epclusa from wholesalers by mid-August 2016.

The pharmaceutical company has stated: "To assist eligible HCV patients in Canada with access to Epclusa, Gilead Canada has added Epclusa to the Gilead Momentum Support Program, which provides information to patients and healthcare providers to help ensure patient access to medication." Patients who may be interested in the use of Epclusa should first speak to their healthcare provider. For more information regarding the Momentum Support Program in Canada, call 1.855.447.7977.

Only in BC you say? Check it out - "approved" does not mean "available", to all people, in every Province. Apparently I could, between Aug 24 and Sep 21 lobby BC Pharmacare to say, "Yes, please - make Epclusa available via Pharmacare in BC" - that doesn't mean that Epclusa would then be available to me or anyone anytime soon! Even today, I (as a "former" GT 3a, I love saying that BTW - "former"!)) I would still not be able to get even Daklinza easily! I have watched Daklinza stalled in BC Pharmacare since at least July of 2015! Good grief,  GT3's still wait (along with all the other 1 thru 6 GT's that Epclusa could be helping today)! Hm, let's hope they work out the MONEY part of our liver problem, sometime soon!

Not to worry Tig,

Yesterday you were only as "Old as Dirt" ...

it's today that you're actually "Older Than Dirt" ... so you got at least a whole day's reprieve there.

"OLDER THAN DIRT"?  Boo Hoo, Hoo.... I'm silently weeping in my bonfire of candles on my non existent cake, lol! I didn't even get a darn cake! I asked for a DQ ice cream cake and the blasted place was out! How dare they! Do they not realize the importance of this day? I hope you will be kind enough to find one and send it. Overnight FedEx and dry ice should do the trick, ha, ha!

Respect and deference is always foremost in my thoughts, especially when it is followed up with a nice DQ Toffee ice cream cake! YUM, YUM, YUM..... biggrin

Wendy,

Back so soon! Glad it was good.

Are you trying to be nice to TIG because it is his birthday (that's the rumour anyway) and because he is wise, benevolent and older than dirt?

I figured out that that is why you complimented him with that "TYG = Thank you God". hee hee 

Tig, I will have you know I am your senoir and as an elder I expect some respect and deference man. wink hee hee - wheee!

Dave you will be pleased to know I did not eat any doughnuts and drank more water than coffee lol. 

Had a great time with my other family. Worked registration, saw lots of old friends and heard 2 great speakers. Canuck, one was from Canada! Saw 2 of my counselors from when I was in treatment 25 years ago. (they all had bets I would never make it) I am beyond blessed to have this community as well as that one in my life. TYG = Thank you God!

Wendy, I've been to 3 different kinds of AA meetings, I did not go exactly for the usual reasons some people might go, but I wanted to go and did, and was warmly welcomed. It was a really good learning thing for me, and an eye opener, a very good positive encounter. I quickly was awed at the depths of us, in all our glory of strengths, sober honesty and humbling weaknesses. I never so quickly bonded, related, cried and laughed with a group of people faster with these 3 different groups who were as diverse as any group can be. I gained immediate respect for people who were struggling and winning. I benefited for it and learned a lot. I was so impressed by this group of people, much like how I am impressed by this group of people. C.

Finally! A wee bit more about the NS3/4A, "Vox", that I and Pablito consumed, along with our 8 weeks of sof/vel (Epculsa)! And which webtomass also consumed along with his 12 weeks of sof/vel. Nothing too earth shattering/riveting here, but, at least they are starting to publish some data about "vox"! smile

Edited: There was personally identifiable info in that link. Medscape articles post better if you can find or post in PDF.

Whal-dern-it all. Infuriating this! Don't know HOW to do stuff on computer!! Quite a few times I can't post things no matter how much I fash around with them, photos/PDF's are the worst! hmmph. I just have NO aptitude for learning computer stuff I am afraid. Try this? - it is the title and place the thing lives ...

Thanks Canuck! Very promising news. Now if we can just see Big Pharm climb on-board and all of the regulatory agencies approve it. It's amazing how much it actually costs to provide these medications when money isn't the primary objective.

Hey Canuck,

A lot of jaw dropping information in that relatively short text ...

Time to get with the program ... get the logistics figured out, the costs down and get people treated.

At least now there is a way where not long ago we couldn't say that.

"Currently, less than 1 million people are being treated for hepatitis C worldwide, according to our analysis of exported raw materials," Hill said. "By contrast there are an estimated 2 to 4 million new infections with hepatitis C each year. So unless we increase the numbers of people treated, the epidemic of hepatitis C will continue worldwide." - by Will Offit

Thanks for another very interesting read.

Sof/Vel - Current/Future pricing?

Novel HCV DAAs could be mass-produced under $90 per person

July 26, 2016

If international donors place larger orders, novel direct-acting antivirals to treat hepatitis C could be mass-produced for under $90 per person, according to data presented at AIDS 2016.

"A course of treatment to cure hepatitis C could be mass produced for under $90 per person, if we can follow the same methods of production used to treat 17 million people with HIV/AIDS using antiretrovirals," Andrew Hill, PhD, senior visiting research fellow in the pharmacology department at Liverpool University, told Infectious Disease News. "For this to happen, we need international donors or national health authorities to place large orders for treatment. We would need orders for at least 1 million courses of treatment to achieve the $90-unit price."

Andrew Hill

Novel DAAs can achieve sustained viral response rates above 90%, according to Hill and colleagues. However, the lowest price for a 12-week course of Sovaldi (sofosbuvir, Gilead Sciences) is $324 and "access" prices are available in countries only covering 50% of the worldwide epidemic, they said.

To measure how prices for novel DAAs are beginning to fall, the researchers extracted data from the first half of 2016 on the per-kilogram prices of exported active pharmaceutical ingredient (API) and exported volumes and determined per-pill API costs according to daily dosage. They estimated a cost of $0.04 per pill for formulation and excipients, $0.35 a month for packaging and a 50% profit margin.

They found that the total exports from India during this period were 10.2 tons of sofosbuvir, which is equivalent to 303,000 12-week treatment courses; 5,443 kg of Daklinza (daclatasvir Bristol-Myers Squibb), which is equivalent to 1,080,000 courses; and 240 kg of ledipasvir (Gilead Sciences), which is equivalent to 32,000 courses.

API prices decreased during this period. At the end of May 2016, the API price was $1,094/kg for sofosbuvir, $998/kg for daclatasvir, $2,441/kg for ledipasvir and between $8,900 and $11,700/kg for velpatasvir. Prices in the United States were 1,355 times higher than the target price for sofosbuvir, 4,500 times higher for daclatasvir, 984 times higher for Harvoni (ledipasvir/sofosbuvir, Gilead Sciences) and between 346 and 413 times higher for Epclusa (sofosbuvir/velpatasvir, Gilead Sciences).

Overall, 12-week treatments of sofosbuvir can be manufactured for $62, sofosbuvir plus ledipasvir for $96, daclatasvir for $14 and sofosbuvir plus velpatasvir for between $181 and $216, all of which include a 50% profit margin.

"Currently, less than 1 million people are being treated for hepatitis C worldwide, according to our analysis of exported raw materials," Hill said. "By contrast there are an estimated 2 to 4 million new infections with hepatitis C each year. So unless we increase the numbers of people treated, the epidemic of hepatitis C will continue worldwide." - by Will Offit
