|---|---|---|---|
| Experimental Drug | Experimental | single oral dose radiolabelled 50mg of SHP626 |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| SHP626 | Drug | single oral dose 50mg SHP626 with approximately 5.95 μCi RAD |
| |
| Measure | Description | Time Frame |
|---|---|---|
| Pharmacokinetic parameters will be determined from the plasma and blood concentration time data of total radioactivity and from the plasma concentration-time data for SHP626 by non-compartmental analysis. | Day 1 to day 10 | |
| Total radioactivity (RAD) in whole blood and plasma | Day 1 to day 10 | |
| To determine the total RAD in urine and feces. | Day 1 to day 10 | |
| Maximum plasma concentration (Cmax) of 50mg [14C]-SHP626 and RAD occurring at time of maximum observed concentration (tmax) | Day 1 to day 10 | |
| Area under the plasma concentration curve (AUC0-t) of 50mg [14C]-SHP626 and RAD from the time of dosing to the last measurable concentration | Day 1 to Day 10 | |
| Area under the plasma concentration curve (AUC0-∞ ) of 50mg [14C]-SHP626 and RAD extrapolated to infinity, calculated using the observed value of the last non-zero plasma concentration | Day 1 to Day 10 | |
| First order rate constant associated with the terminal portion of the plasma curve terminal half-life (t½) for 50mg [14C]-SHP626 and RAD | Day 1 to Day 10 | |
| Total body clearance (CL/F ) of 50mg [14C]-SHP626 and RAD for extravascular administration divided by the fraction of dose absorbed | Day 1-10 | |
| Volume of distribution (Vz/F ) of 50mg [14C]-SHP626 and RAD associated with the terminal slope following extra-vascular administration divided by the fraction of dose absorbed |
| Measure | Description | Time Frame |
|---|---|---|
| Characterize and identify metabolites of [14C]-SHP626 in plasma by accelerator mass spectrometry for radioactivity quantification | Metabolites in the excreta and/or plasma will then be structurally identified by a combination of techniques such as co-chromatography with authentic reference standards, high performance liquid chromatography-mass spectrometry, and other spectroscopic techniques if necessary |
