Ongoing Clinical Trials of HCV Therapy in the HIV Co-infected • As of November 2012, the following regimens are under ongoing study: • IFN-containing (only for HCV genotype 1) • PegIFN-2a + RBV* + NS3 Protease Inhibitors • PegIFN-2a + RBV + telaprevir • PegIFN-2a + RBV + simeprevir • PegIFN-2a + RBV + faldaprevir • PegIFN-2a + RBV + NS5A Inhibitor • PegIFN-2a + RBV + daclatasvir • IFN-sparing (only for HCV genotypes 2 & 3) • Sofosbuvir (nucleotide polymerase inhibitor) + RBV * RBV = ribavirin www.clinicaltrials.gov
Two Ongoing Studies of PegIFN-2a + RBV + Telaprevir in the HIV Co-Infected * Telaprevir dosed 1125 mg TID in patients receiving efavirenz www.clinicaltrials.gov
Ongoing Study of PegIFN-2a + RBV + Simeprevir in the HIV Co-Infected www.clinicaltrials.gov
Ongoing Study of PegIFN-2a + RBV + Faldaprevir in the HIV Co-Infected www.clinicaltrials.gov
PegIFN-2a + RBV + Faldaprevir for HCV GT1 in HCV Treatment-Naïve and Relapser Patients with HIV Co-infection PegIFN/RBV PegIFN/RBV Faldaprevir 240 mg QD + PegIFN/RBV Follow-up: up to Week 120 Faldaprevir 240 mg QD + PegIFN/RBV PegIFN/RBV * Faldaprevir 120 mg QD + PegIFN/RBV PegIFN/RBV Day 1 Week 12 Week 24 Week 48 Week 120 Randomization (1:1) Randomization (1:1) ETS patients are re-randomized (1:1) No ETS = 48 weeksPegIFN/RBV ETS (early treatment response): HCV RNA <25 IU/mL, detectable or not at Week 4 and <25 IU/mL, undetectable at Week 8 * Patients directly assigned to the 240 mg dose group if receiving efavirenz and to the 120 mg dose group if receiving darunavir/ritonavir or atazanavir/ritonavir
Ongoing Study of PegIFN-2a + RBV + Daclatasvir in the HIV Co-Infected www.clinicaltrials.gov
Ongoing Study of Sofosbuvir + RBVin the HIV Co-Infected www.clinicaltrials.gov
Future Trials of Anti-HCV Therapy Anticipated in the HIV Co-infected • Following completion of DDI studies identifying compatible ARVs, the following promising IFN-free anti-HCV regimens in the HCV-mono-infected may be tested in the HIV+ population: • Sofosbuvir + RBV (likely GT 2 and 3 only) • Sofosbuvir + NS5A inhibitor (likely pangenotypic) • SOF + GS-5885 fixed-dose combination (FDC) • SOF + Daclatasvir • NS3 + NNI + RBV (GT1 only) • Faldaprevr + BI-207127 + RBV in GT1b or GT1a/IL-28B CC • Telaprevir + VX-222 + RBV • NS3 + NNI + NS5A ± RBV • ABT-450/ABT-267/RTV (FDC) + ABT-333 ± RBV
