1 Traitement de l’Hépatite C Sans Interféron Patrick Marcellin

2 Hepatitis C

3 Where we are: The achievements

4 Hepatitis C: progress is accelerating  Cure = 100% in 10 years The conclusion of the PHC 2009

5 Progress is accelerating Earlier ? 2015 ?

6 Where we are Better understanding of therapeutic targets Protease Inhibitors Polymerase Inhibitors NS5A Inhibitors

7 Where we are Better efficacy with triple therapy (G1) BI 2012 TRI 0 70% 40% +30% Jacobson et al. NEJM 2012 Poordad NEJM 2012

8 SVR = CURE  Undetectable HCV RNA in serum: 100%  Undectable HCV RNA in liver: ≈100%  Undectable HCV RNA in PBMCs: 100% Marcellin et al. Annals of Intern Madicine 1997 Maylin et al. Gastroenterology 2009

9 Cure = improved prognosis HCC in 300 cirrhotics Cardoso et al. J Hepatol SVR (+) SVR (-) p < Time since last treatment (years) 10 0

10 Cure = improved prognosis Survival in 300 cirrhotics 0 0,2 0,4 0,6 0,8 1,0 SVR (+) SVR (-) p < Time since last treatment (years) 0,0 Cardoso et al. J Hepatol 2010

11 Reinforced screening and access to therapy= decrease in HCV-related mortality Deuffic-Durban et al. EASL 2011 Percentage of decreased mortality modelisation 2012 – 2021 France PEG-IFN + RBV Tritherapy PEG IFN + RBV + PI Tritherapy + reinforced screening + improved access to therapy % - 19 % %

12 Where we are: the limitations

13 Where we are: limitations Insufficient screening Undiagnosed Pool 2.5 million Diagnosed Pool 0.9 million Undiagnosed Pool 1.8 million Diagnosed Pool 1.6 million

14 Where we are: limitations 170 million people HCV infected worldwide US 4M Brazil 7M Europa 5M Russia 3M Egypt 12M India 10M China 43M Korea 1M Japan 2M Vietnam 7M Pakistan 9M

15 Where we are: limitations Insufficient access to treatment

16 Where we are: limitations Access to treatment: the bottle necks DiagnosedManagedTreatedCured

17 Where we are: limitations US 4M Brazil 7M Europa 5M Russia 3M Egypt 12M G4 India 10M G3 China 43M Korea 1M Japan 2M Vietnam 7M G6 Pakistan 9M G3 High prevalence of G non1 in high prevalence countries

18 Where we are: The hope is becoming reality

19 Ideal Therapy  100% efficacy  IFN-free  All oral  Short duration  No resistance  Pan-genotypic  Well tolerated and safe  Low cost

20 Where we go Lok et al. NEJM BMS BMS PEG IFN + RBV % BMS BMS Quadruple therapy: PEG-IFN+ RBV+ NS5AI + PI in G1 null responders: IFN free

21 danoprevir + mericitabine + ribavirine in non responders G 1 n/N Partial RespondersNull Responders % Feld JJ, AASLD /319/23 SVR 12

24 Years incidence annuelle de la mortalité liée au VHC Without treatment With bitherapy PEG IFN + RBV -14% -32% G1/4 G2/3 Impact of treatment on mortality Deuffic-Durban et al. J Hepatol 2007

25 Reinforced screening and access to therapy= decrease in HCV-related mortality Deuffic-Durban et al. EASL 2011 PEG-IFN + RBV Tritherapy PEG IFN + RBV + PI Tritherapy + reinforced screening + improved access to therapy Percentage of decreased mortality modelisation 2012 – 2021 France % + 19 %

26 Where we go: IFN free Therapy

35 The Proof of Concept 100% efficacy All oral IFN-free Short duration No resistance Pan-genotypic Well tolerated and safe Low cost ? ?

36 Hepatitis C: progress is accelerating  Cure = 100% in 2-3 years  One pill a day The conclusion of the PHC 2009

37 Where we are: limitations Insufficient access to treatment
