  17. Study M12-999: Design • 3D: co-formulated ABT-450/r/ombitasvir, 150 mg/100 mg/25 mg QD; dasabuvir, 250 mg BID • RBV: dosing was managed at the discretion of the investigator and closely monitored per protocol SVR12 3D + RBV (N=34) Day 0 Week 24 To Week 72 Kwo P, et al. 49th EASL; London, England; April 9-13, 2014. Abst. O114.

  18. Study M12-999:Calcineurin Inhibitor (CNI) Dosing with 3D Regimen • A phase 1 drug-drug interaction study demonstrated that dosing tacrolimus (TAC) or cyclosporine (CYA) with the 3D regimen compared to either alone resulted in a: • 7-fold increase in TAC half-life • 3-fold increase in CYA half-life • Based on these findings, recommended dosing during 3D treatment was: • TAC • 0.5 mg once weekly or • 0.2 mg every 3 days • CYA • 1/5 of the daily pre-3D treatment dose given once daily Kwo P, et al. 49th EASL; London, England; April 9-13, 2014. Abst. O114.

  19. Study M12-999:Preliminary Efficacy Results • No patient had breakthrough • One patient had a relapse (post-treatment day 3) • At the time of relapse, this patient had R155K in NS3 protease, M28T+Q30R in NS5A, and G554S+G557R in NS5B, none of which were present at baseline Percentage Patients 34/34 34/34 32/33 25/26 Kwo P, et al. 49th EASL; London, England; April 9-13, 2014. Abst. O114.

  20. Study M12-999: Pre-Treatment and On-Treatment TacrolimusCtrough Concentrations • Ctroughlevels were comparable pre-treatment and on-treatment • TAC dose was 0.5 to 1.0 mg at 1-2 week intervals for most patients • 4 patients experienced a TAC level >15 ng/mL (15.7-34.0 ng/mL) • All 4 patients had TAC dosing errors • 2 patients had associated creatinine increases (1.8 and 1.4 mg/dL), which normalized when dosing was corrected Tacrolimus Concentration (ng/mL) (Treatment Weeks 1-4) Kwo P, et al. 49th EASL; London, England; April 9-13, 2014.
