Outcome Measures

Primary Outcome Measures

Part 1 and 2: Safety assessed by adverse events, vital signs, laboratory tests, electrocardiogram (ECGs), collagen and adenosine diphosphate (ADP)-induced platelet aggregation, and gastrointestinal (GI) safety assessments (Part 2 only) [Up to Day 20]

Secondary Outcome Measures

Part 1: Pharmacokinetics (PK) profile of ASP7657 after a single dose in plasma: AUCinf, AUClast, tlag, tmax, Cmax, t 1/2, Vz/F, CL/F [Day 1]
Area under the concentration-time curve (AUC) from the time of dosing extrapolated to time infinity (AUCinf), AUC from the time of dosing to the last measurable concentration (AUClast), time prior to the time corresponding to the first measurable (nonzero) concentration (tlag), time of maximum plasma concentration (tmax), maximum plasma concentration (Cmax), terminal elimination half-life (t ½), apparent volume of distribution during the terminal elimination phase after extravascular dosing (Vz/F), and apparent total systemic clearance after single or multiple extravascular dosing (CL/F)
Part 1: PK profile of ASP7657 in urine: Aelast, Aeinf, Aelast%, Aeinf%, CLr [Day 1]
Cumulative amount of drug excreted in urine from time of dosing up to the collection time of the last measurable concentration (Aelast), cumulative amount of drug excreted in urine from time of dosing extrapolated to time infinity (Aeinf), percent of drug dose excreted in urine from time of dosing up to the collection time of the last measurable concentration (Aelast%), percent of drug dose excreted in urine from time of dosing extrapolated to time infinity (Aeinf%), renal clearance (CLr)
Part 1: Pharmacodynamics (PD) profile of tumor necrosis factor alpha (TNF-α) in whole blood: maximum response (Rmax), area under the dose-response curve (AURC), and time to reach maximum response (tmax,R) [Day 1]
Part 1: PD in urine: Total urine volume over 24 hours [Day -1 and Day 1]
Part 2: PK profile of ASP7657 after first dose in plasma: tlag, tmax, Cmax and AUC from the time of dosing to 24 hours postdose (AUC24) [Day 1]
Part 2: PK of ASP7657 in plasma: concentration immediately prior to dosing at multiple dosing (Ctrough) [Days 2, 4, 6, 8, 10 and 12]
Part 2: PK profile of ASP7657 after last dose in plasma: AUC from the time of dosing to the start of the next dosing interval (AUCtau), tmax, Cmax, t ½, Vz/F, CL/F, Accumulation ration (Racc), peak-trough ratio (PTR) [Day 14]
PK profile of ASP7657 after last dose in urine: Aetau, (Aetau%), and CLr [Day 14]
Cumulative amount of drug excreted in urine from the time of dosing to the start of the next dosing interval (Aetau), percent of drug dose excreted in urine over the time interval between consecutive dosing (Aetau%)
Part 2: PD profile of plasma renin activity and aldosterone [Days -1, 7, and 14]
Part 2: PD of urine electrolytes: amount excreted over 24 hours (Ae24) [Days -1 and 14]
