Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pharmacokinetics of simvastatin and simvastatin acid (Cmax) | 9 days | To evaluate the potential effect of multiple oral doses of voclosporin on the single-dose PK of simvastatin and the active metabolite simvastatin acid. Maximum observed concentration (Cmax). |
| Pharmacokinetics of simvastatin and simvastatin acid (AUC) | 9 days | To evaluate the potential effect of multiple oral doses of voclosporin on the single-dose PK of simvastatin and the active metabolite simvastatin acid. Area under the concentration-time curve (AUC) from time zero to infinity. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Pharmacokinetics of voclosporin (Tmax) | 9 days | To evaluate voclosporin blood concentrations - Time to reach maximum observed plasma concentration (Tmax). |
| Pharmacokinetics of voclosporin (Ctrough) | 9 days | To evaluate voclosporin blood concentrations - Trough concentration (Ctrough) at the end of a dosing interval at steady state. |
| Pharmacokinetics of voclosporin (CL/F) | 9 days | To evaluate voclosporin blood concentrations - apparent clearance (CL/F). |
| Pharmacokinetics of voclosporin (Cmax) | 9 days | To evaluate voclosporin blood concentrations - Cmax. |
| Number of participants with abnormal vital signs | Up to 2 weeks | Number of participants with abnormal vital signs (eg., blood pressure, heart rate, body temperature, respiratory rate) will be assessed |
| 12-Lead Electrocardiogram Assessment | Up to 2 weeks | Standard 12-lead electrocardiograms (eg., QTcF interval) will be summarized by observed value and change from baseline values. |
| Number of participants with abnormal laboratory test results | Up to 2 weeks | Number of subjects with abnormal laboratory test results (eg., hematology, biochemistry and urinalysis) will be assessed |
| Pharmacokinetics of voclosporin (AUC) | 9 days | To evaluate voclosporin blood concentrations - AUC from time zero to 12 hours. |
