Portugal's roll-out of HCV therapy with DAAs achieves impressive results

Roll-out of hepatitis C virus (HCV) therapy using direct acting antivirals (DAAs) has achieved excellent outcomes in Portugal, data presented to the International Liver Congress in Barcelona shows. Overall, 96% of patients had a sustained virological response (SVR) to therapy with a 100% response seen in some sub-sets. Treatment also worked well for people with cirrhosis, achieving SVR rates of between 84 and 94%. Treatment response was unaffected by HIV co-infection, previous HCV therapy or older age.

Standard therapy for HCV is based on the DAAs ledipasvir/sofosbuvir (LDV/SOF) or sofosbuvir (SOF). This therapy has been associated with excellent outcomes in randomised controlled trials, with over 90% of patients having a sustained virological response to therapy twelve weeks after the completion of treatment (SVR12).

In February 2015, Portugal initiated a policy granting universal access to HCV therapy with ledipasvir/sofosbuvir or sofosbuvir. In the present study, investigators analysed outcomes among people who received this therapy in the first year after its roll-out.

Approximately 5500 started treatment and data were available for 1069 individuals who completed treatment and were assessed for SVR by the end of January 2016.

The patients had a mean age of 52 years, 70% were male, 77% had HCV genotype 1, 27% had HIV co-infection and 66% had previously taken a course of HCV therapy.

The vast majority (94%) of patients were treated with ledipasvir/sofosbuvir. The overall SVR rate (SVR12 or SVR24) was 94%. However, 100% response rates were seen in some sub-sets.

Response rates among people with cirrhosis varied between 84 and 94%, with the poorest SVR rate observed in people with genotype 3 and the best in people with genotype 1.

Overall, people with genotype 1 were more than two-times more likely to achieve SVR compared to people with other HCV genotypes (OR = 2.6; 95% CI, 1.4-5.0; p = 0.003). Cirrhosis was associated with an 80% reduction in the chance of achieving SVR (OR = 0.2; 95% CI, 0.1-0.4; p < 0.001).

HIV co-infection (97% SVR rate), age and previous HCV treatment history did not have a significant impact on treatment outcomes.

The results underlined that patients with genotype 3 and cirrhosis – a historically difficult-to-treat population – had poorer outcomes than other sub-groups of patients.

“Real-life data demonstrates that hepatitis C treatment with universal access to LDV/SOF and SOF-based regimens is associated with very high SVR rates, irrespective of HCV genotype involved,” conclude the researchers.

Community Consensus Statement on Access to HIV Treatment and its Use for Prevention

Together, we can make it happen

We can end HIV soon if people have equal access to HIV drugs as treatment and as PrEP, and have free choice over whether to take them.

Launched today, the Community Consensus Statement is a basic set of principles aimed at making sure that happens.

The Community Consensus Statement is a joint initiative of AVAC, EATG, MSMGF, GNP+, HIV i-Base, the International HIV/AIDS Alliance, ITPC and NAM/aidsmap
