ABSTRACT
BACKGROUND:
Few direct anti-hepatitis C virus (HCV) agents have been studied in difficult-to-treat null responder and cirrhotic human immunodeficiency virus (HIV)-coinfected patients. Daclatasvir and asunaprevir combined with pegylated interferon/ribavirin (peg-IFN/RBV) have shown promising results in HCV-monoinfected patients.METHODS:
An open-label, single-arm, phase 2 study was conducted in HIV/HCV genotype 1/4-coinfected patients who were null responders to prior peg-IFN/RBV standard therapy and on a raltegravir-based regimen with HIV RNA <400 copies/mL. They received a 4-week lead-in phase with peg-IFN/RBV, followed by 24 weeks of asunaprevir (100 mg twice daily), daclatasvir (60 mg once daily), and peg-IFN/RBV. The primary endpoint was sustained virologic response 12 weeks after the end of treatment (SVR12) using intent-to-treat analysis.RESULTS:
Seventy-five patients were included, of whom 27 (36%) had cirrhosis. The median baseline CD4 count was 748 (interquartile range, 481-930) cells/µL. The global SVR12 rate was 96.0% (95% confidence interval [CI], 88.8%-99.2%; n = 72/75), 92.6% (95% CI, 75.7%-99.1%; n = 25/27) in cirrhotic patients, 94.6% (95% CI, 81.8%-99.3%; n = 35/37) in genotype 1 patients, and 97.4% (95% CI, 86.2%-99.9%; n = 37/38) in genotype 4 patients. Six patients (8%) stopped HCV therapy prematurely 2 due to HCV breakthrough, 4 to adverse events (1 lung cancer, 3 infections). One patient with cirrhosis (with baseline platelet count <150 000 platelets/µL and albuminemia <35 g/L) died from multiorgan failure. Overall, 36 serious adverse events occurred in 21 (28%) patients. No HIV breakthrough was observed.CONCLUSIONS:
In HIV/HCV genotype 1/4-coinfected null responders, a 24-week regimen combining daclatasvir, asunaprevir, and peg-IFN/RBV was associated with a very high cure rate. The safety profile was acceptable, even though cirrhotic patients with low albuminemia and platelets should be monitored closely. This combination is a new option in this difficult-to-treat population. CLINICAL TRIALS REGISTRATION NCT01725542.Palabras clave
