This study aimed to describe the effectiveness of OBV/PTV/r ± DSV (3D/2D regimen) with or without ribavirin (RBV) in HCV or HCV/HIV co-infected patients with GT1/GT4 and CKD (IIIb-V stages), including those under hemodialysis and peritoneal dialysis in routine clinical practice in Spain in 2015. Material and methods: Non-interventional, retrospective, multicenter data collection study in 31 Spanish sites. Socio-demographic, clinical variables, study treatment characteristics, effectiveness and tolerability data were collected from medical records. Results: Data from 135 patients with a mean age (SD) of 58.3 (11.4) years were analyzed: 92.6% GT1 (81.6% GT1b and 17.6% GT1a) and 7.4% GT4, 14 (10.4%) HIV/HCV co-infected, 19.0% with fibrosis F3 and 28.1% F4 by FibroScan®, 52.6% were previously treated with pegIFN and RBV. 11.1%, 14.8% and 74.1% of patients had CKD stage IIIb, IV and V respectively. 68.9% of patients were on hemodialysis; 8.9% on peritoneal dialysis and 38.5% had history of renal transplant. A total of 125 (96.2%) of 135 patients were treated with 3D, 10 (7.4%) with 2D and 30.4% received RBV. The overall intention-to-treat (ITT) sustained virologic response at week 12 (SVR12) was 92.6% (125/135) and the overall modified-ITT (mITT) SVR12 was 99.2% (125/126). The SVR12 rates (ITT) per sub-groups were: HCV mono-infected (91.7%), HCV/HIV co-infected (100%), GT1 (92.0%), GT4 (100%), CKD stage IIIb (86.7%), stage IV (95%) and stage V (93%). Among the 10 non-SVR there was only 1 virologic failure (0.7%); 4 patients had missing data due lost to follow up (3.0%) and 5 patients discontinued 3D/2D regimen (3.7%): 4 due to severe adverse events (including 3 deaths) and 1 patient´s decision. Conclusions: These results have shown that 3D/2D regimens are effective and tolerable in patients with advanced CKD including those in dialysis with GT 1 or 4 chronic HCV mono-infection and HIV/HCV coinfection in a real-life cohort. The overall SVR12 rates were 92.6% (ITT) and 99.2% (mITT) without clinically relevant changes in eGFR until 12 weeks post-treatment. These results are consistent with those reported in clinical trials. ; MCL has served as consultant for AbbVie, MSD, Janssen, BMS and Gilead; MRB has received grant research from Gilead Science, and speaker fees from AbbVie, Gilead and MSD; MR has received speaker fees from AbbVie; MD has received grant support and consultancy fees from AbbVie, Bayer, Bristol-Myers Squibb, Gilead and Merck, Sharp & Dhome; FGR has served as speaker for AbbVie, Gilead and BMS; MLM has served as a speaker for AbbVie, BMS, Gilead, Janssen, MSD and ViiV; as a consultant for AbbVie, BMS and Janssen and has received research funding from FIPSE 36465/03, FIPSE 36680/07.-NEAT IG5 (NEAT is a project funded by the European Union under the 6th Framework programme) contract number LSHP-CT-2006-037570; MAC has served as a consultant for Gilead and and ViiV healthcare, and has received speaker fees from Janssens, Gilead, ViiV Healthcare; MMA reports personal fees from ViiV Healthcare, Gilead Sciences, Merck, Janssen, AbbVie and ABBOTT Laboratories, outside the submitted work; AR has received consultancy and speaker fees from AbbVie, Gilead Sciences and Merck Sharp & Dohme; JM has received honoraria, speaker fees, consultant fees or funds for research from AbbVie, BMS, Boehringer-Ingelheim, Gilead, Janssen, MSD, Roche and ViiV; EGP has received speaker fees from AbbVie and Gilead; LGB has served as consultant for AbbVie and Intercept and has received speaker fees from Gilead and MSD; AA, RMG, CB, TAE, MLG, BPL, IC, SB, LB, JGS, MJP, IMG, LM, IdlS, ML and JEL don't have a financial interest or affiliation with one or more organizations that could be perceived as a real or apparent conflict of interest in the context of the subject of this paper; CdA and AM are paid employees of AbbVie and may hold stock or options.

Aim We describe the effectiveness and safety of the interferon-free regimen ombitasvir/paritaprevir/ritonavir plus dasabuvir with or without ribavirin (OBV/PTV/r ± DSV ± RBV) in a nationwide representative sample of the hepatitis C virus (HCV) monoinfected and human immunodeficiency virus-1/hepatitis C virus (HIV/HCV) coinfected population in Spain. Material and methods Data were collected from patients infected with HCV genotypes 1 or 4, with or without HIV-1 coinfection, treated with OBV/PTV/r ± DSV ± RBV at 61 Spanish sites within the initial implementation year of the first government-driven "National HCV plan." Effectiveness was assessed by sustained virologic response at post-treatment week 12 (SVR12) and compared between monoinfected and coinfected patients using a non-inferiority margin of 5% and a 90% confidence interval (CI). Sociodemographic and clinical characteristics or patients and adverse events (AEs) were also recorded. Results Overall, 2, 408 patients were included in the intention-to-treat analysis: 386 (16%) were patients with HIV/HCV. Patient selection reflected the real distribution of patients treated in each participating region in Spain. From the total population, 96.6% (95% CI, 95.8–97.3%) achieved SVR12. Noninferiority of SVR12 in coinfected patients was met, with a difference between monoinfected and coinfected patients of -2.2% (90% CI, -4.5% - 0.2%). Only genotype 4 was associated with non-response to OBV/PTV/r ± DSV ± RBV treatment (p<0.001) in the multivariate analysis. Overall, 286 patients (11.9%) presented AEs potentially related to OBV/PTV/r ± DSV, whereas 347 (29.0%) presented AEs potentially related to ribavirin and 61 (5.1%) interrupted ribavirin. Conclusions Our results confirm that OBV/PTV/r ± DSV ± RBV is effective and generally well tolerated in a representative sample of the HCV monoinfected and HCV/HIV coinfected population in Spain within the experience of a national strategic plan to tackle HCV.

Conclusions ...
This book proposes an integrated approach to patent risk and capital budgeting in pharmaceutical research and development (R and D), developing an option-based view (OBV) of imperfect patent protection, which draws upon contingent-claims analysis, stochastic game theory, as well as novel numerical methods. The text re-initiates a discussion about the contribution of quantitative frameworks to value-based R and D management.
