I am waiting for Vosevi, a few questions
« on: May 20, 2018, 10:02:28 am »
I have relapsed after Viekira and Exviera in November 2015, genotype 1b.

Now I am waiting for Vosevi which I hope to get in October. I am still thinking if I should not take Ribavirin additionally. I do not want to take it.


1. How many people from the forum where taking Vosevi for genotype 1b? Do you know anyone, any real-time data? If you know anyone on the forum please let me know.
 
2. I am trying to explain WHY Viekira+Exviera did not work for the L31M. Is it supposed not to work for this well? 


From my findings:
NS-3 condones covered 1-181
NS3 region (w.r.t M58335) - S7A, V48I, A66G, P86Q, K87A, P89S, F147L, V170l
Ns3 region (w.r.t H77) - I35V, T42S,T61S, R62K, I64L, S66G, V71I,I72T, P86Q, Q89S, , S91A, I132V, A147L, L153I, N174S, L175M

For your first question per the AASLD it looks like your odds of cure from clinical trial data is 100% I see no recommendation for ribavirin. See below

For your second question your reasearch is well beyond my capabilities so I leave that up to the molecular biologists. However, unless the odds of your initial treatment were 100% that would indicate it doesn’t work for everyone all the time. I relapsed with a 12 week treatment Sovaldi/ Olysio and later treated successfully with 24 weeks of Harvoni ribavirin. I know we will wonder why we fell on the wrong side of the data but we will likely never know. Several people here have had to be treated again and are now cured. I wish you the best and a successful treatment.

NS5A Inhibitor DAA-Experienced, Genotype 1 Patients With or Without Compensated Cirrhosis

Recommended Regimen
Sofosbuvir/Velpatasvir/Voxilaprevir
The placebo-controlled, phase 3 POLARIS-1 trial evaluated a 12-week course of the daily fixed-dose combination of sofosbuvir (400 mg)/velpatasvir (100 mg)/voxilaprevir (100mg) in patients with a prior NS5A inhibitor-containing DAA regimen. The majority (61%) experienced a failure with a combination regimen of an NS5B inhibitor plus an NS5A inhibitor, such as sofosbuvir/ledipasvir (Bourliere, 2017). The overall SVR12 rate was 97% (146/150) in genotype 1-infected patients. SVR12 rates were 96% (97/101) for participants with genotype 1a infection and 100% (45/45) for those with genotype 1b infection. A single genotype 1-infected patient experienced relapse; this individual had subtype 1a infection and cirrhosis. Baseline RASs and the presence of cirrhosis were not significant predictors of virologic failure in genotype 1 infection. Serious adverse events were similar between the placebo and treatment arms; only 1 patient discontinued therapy due to an adverse event. Headache, diarrhea, and nausea were more common in those patients receiving sofosbuvir/velpatasvir/voxilaprevir compared to placebo.
