Figure 5.

Simulated concentration‐time profile for coadministration of tacrolimus 0.5 mg every 7 days with the 3D regimen. QD, once daily; BID, twice daily. Note: The plot illustrates the timeline from the time a patient undergoes transplant through the first 2 weeks of 3D (ABT‐450/ritonavir 150/100 mg once daily, ombitasvir 25 mg once daily, and dasabuvir 400 mg twice daily) treatment. The mean concentration‐time profile for tacrolimus is shown (black and blue lines). The grey lines illustrate the tacrolimus profile in the absence of 3D treatment. Subjects were assumed to have a stable tacrolimus Ctrough of 5 ng/mL when initiating 3D treatment. Further modifications in tacrolimus dose or dosing frequency should be guided by trough levels measured during coadministration with the 3D regimen.
