2 HIV / Hepatitis C CoInfection  HIV infection as a roadmap for HCV and Coinfection  HIV/ Hep C Coinfection overview  Coinfection guidelines  Coinfection trial outcomes  Future coinfection regimens  Pharmacology of ART/ DAA

3 “Working with drug addicts brings out some of health care providers’ worst fears, prejudices, and feelings of powerlessness.” “It is arrogant for a doctor (nurse) to presume - yet we do it all the time - that we can suddenly put a stop to a patient’s drug addiction, which by the time we first see the patient has become a powerful, biologically reinforced behaviour that has lasted for years if not decades.” “Our role as care providers is to be there, to bear witness, to be willing to accompany patients through their illness, and to refrain from passing judgment. Neither can we save them nor do we have the right to condemn them.” Peter A. Selwyn, Surviving the Fall: The personal journey of an AIDS doctor. “Working with drug addicts brings out some of health care providers’ worst fears, prejudices, and feelings of powerlessness.” “It is arrogant for a doctor (nurse) to presume - yet we do it all the time - that we can suddenly put a stop to a patient’s drug addiction, which by the time we first see the patient has become a powerful, biologically reinforced behaviour that has lasted for years if not decades.” “Our role as care providers is to be there, to bear witness, to be willing to accompany patients through their illness, and to refrain from passing judgment.

13 HIV impact on Hep C Infection

14 HIV/ Hep C CoInfection Overview:  Teamwork  THANK YOU CAHN nurses !  Open doors: more room at the inn  Increasing clinical and cultural competence  Adherence, adherence, adherence  Beyond coinfection  treatment as engagement in life change

15 Coinfection Overview  HCV 2013 = HIV 1999  Guidelines: here today … gone tomorrow  IFN = child who won’t leave home  Leaky cascade: increase treatment  Health Infrastructure – merge HIV/ HCV treatment systems  Peer involvement : Navigators / Facilitators  Ways forward: look to Europe / cohorts

23 Study 110: SVR24 With TVR + PegIFN/RBV in HCV GT1/HIV-Coinfected Patients  Higher SVR24 rate with TVR-based therapy  No significant drug–drug interactions with TVR and ART  TVR plasma levels similar in patients with or without ART  EFV and ATV/RTV plasma levels similar in patients with or without TVR  No HIV breakthroughs in patients using ART during HCV treatment  Safety and tolerability similar to treatment in patients with HCV monoinfection Sulkowski MS, et al.

25 Higher SVR12 Rates With BOC + P/R vs P/R Alone in HIV/HCV Coinfection  Interim efficacy analysis  3 BOC pts had not yet reached SVR12 time point  HIV-1 RNA breakthrough observed in 7 pts  BOC + P/R: n = 3/64  Placebo + P/R: n = 4/34  Tolerability similar to that seen in HCV monoinfection  Similar rates of total and serious adverse events in BOC and placebo groups  Higher rates of discontinuation due to toxicity with BOC (20%) vs placebo (9%)  Caution needed with drug-drug interactions SVR12 (%) P/R n/N = 9/ / * BOC + P/R *Reflects presented data; speaker noted verbally that remaining 3 pts have now reached and achieved SVR12 Mallolas J, et al.

32 Daclatasvir and Asunaprevir in GT1 HCV Previous Null Responders  AI : randomized, open-label phase IIa study with daclatasvir (NS5A inhibitor) and asunaprevir (NS3 protease inhibitor) Lok AS, et al. AASLD Abstract 79. Noncirrhotic pts with GT1 HCV and previous null response to pegIFN/RBV (N = 101) Daclatasvir 60 mg QD + Asunaprevir 200 mg BID* (n = 18) Daclatasvir 60 mg QD + Asunaprevir 200 mg QD* (n = 20) Daclatasvir 60 mg QD + Asunaprevir 200 mg BID + PegIFN/RBV (n = 20) Daclatasvir 60 mg QD + Asunaprevir 200 mg QD + PegIFN/RBV (n = 21) Daclatasvir 60 mg QD + Asunaprevir 200 mg BID + RBV (n = 22) Wk 24 *Only pts with GT1b HCV included in dual-therapy arms.

33 Outcomes With Daclatasvir + Asunaprevir ± PegIFN or RBV in Null Responders  High response rates with 4-drug regimen of DCV + ASV + pegIFN/RBV  Lower response rates with 2-drug regimen (all GT1b pts)  Better response with ASV 200 mg BID vs ASV 200 mg QD  SVR data from 3-drug arm not reported due to high rate of virologic breakthrough in GT1a but not in GT1b  10 GT1a pts with virologic breakthrough  All triple-therapy pts offered pegIFN  No virologic breakthrough with addition of pegIFN  Virologic breakthrough in 8 pts in 2-drug arms but none in 4-drug arm  3 relapses  1 with DCV + ASV QD  2 with DCV + ASV + PR  All regimens generally well tolerated, with no discontinuations due to toxicity Lok AS, et al.
