Multiple Oral Administration of ASP7991 to Non-elderly Male Subjects

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01872013
Recruitment Status : Completed
First Posted : June 7, 2013

Brief Summary:
This study is to assess the safety, tolerability, plasma concentration and pharmacodynamics of ASP7991 after multiple oral administrations to non-elderly subjects.

Condition or disease Intervention/treatment Phase
Healthy Pharmacokinetics of ASP7991 Drug: ASP7991 Drug: Placebo Phase 1

Detailed Description:
In each step (lowest dose, middle dose, highest dose), subjects are randomly assigned in a double blinded manner to receive either ASP7991 (n=9) or Placebo (n=3) and are administered repeatedly. Once daily, the subjects are administered ASP7991 or placebo orally 30 minutes after breakfast with 150 mL water for 7 days. After the each step the sponsor evaluates the safety in the blinded manner for deciding an escalation to the step.

Actual Study Completion Date : February 2013

Arm Intervention/treatment
Experimental: low dose ASP7991 Drug: ASP7991

Experimental: middle dose ASP7991 Drug: ASP7991

Experimental: high dose ASP7991 Drug: ASP7991

Placebo Comparator: Placebo Drug: Placebo

Primary Outcome Measures :
  1. The safety of ASP7991 assessed by the incidence of adverse events, vital signs, laboratory tests, 12-lead ECGs, ECGs for QT evaluation and slit lamp examination [ Time Frame: For 96 hours after dosing ]

Secondary Outcome Measures :
  1. Plasma concentrations unchanged drug; AUC24h, Cmax, Ctrough, tmax, t1/2, CL/F, Vz/F [ Time Frame: For 96 hours after dosing ]
  2. Urinary concentrations unchanged drug; Aelast, Aelast%, CLR [ Time Frame: For 96 hours after dosing ]
