5. Study Description

Brief Summary
This study is a 2-part study. Part A is a single-dose, open-label study design to determine the PK, safety and tolerability of 5 μg TRK-820 oral administration in subjects with end-stage renal disease (ESRD) who require hemodialysis. Part B is a multiple dose, open-label study design to determine the PK, PD, safety and tolerability of multiple doses in subjects with ESRD who require hemodialysis with refractory uremic pruritus (UP). Each subject will receive 3 doses of TRK-820 (2.5, 5 and 10 μg).
