Randomized Controlled Trial
Exposure-Efficacy Analyses of Ombitasvir, Paritaprevir/Ritonavir with Dasabuvir ± Ribavirin in HCV Genotype 1-Infected Patients.
The three-direct-acting antiviral (DAA) combination regimen of ombitasvir, paritaprevir (coadministered with ritonavir [paritaprevir/ritonavir], and dasabuvir (the 3D regimen) ± ribavirin for treatment of HCV genotype 1-infected patients demonstrated efficacy and safety in Phase II and Phase III clinical trials. The relationships between the steady-state exposure (area under the concentration-time curve at steady state and trough concentration at steady state) of the three DAAs and ribavirin with sustained virologic response at 12 weeks after treatment (SVR12) following administration of the 3D regimen in six Phase II/III studies were examined. ⋯ The results of these analyses indicate that the doses selected for the 3D regimen were optimal, achieving high SVR12 rates across the range of exposures observed in the Phase III studies.

Type 2 diabetes mellitus (T2DM) is a chronic progressive disease that has been spread worldwide over the past three decades and associated with increased morbidity and mortality resulting in considerable socioeconomic implications for national healthcare systems. Effective management of disease is highly needed ensuring patients receive the best possible care within the available budget. The objective of this study was to evaluate the long-term cost-effectiveness of dapagliflozin, a sodium-glucose co-transporter-2 (SGLT-2) inhibitor, compared with a sulfonylurea (SU) or a dipeptidyl-peptidase-4 inhibitor (DPP-4i), when added to metformin, in T2DM patients inadequately controlled on metformin alone in Greece. ⋯ Dapagliflozin in combination with metformin was shown to be a cost-effective treatment alternative for patients with T2DM whose metformin regimen does not provide sufficient glycemic control in a Greek healthcare setting.
