A Safety Study of Ramelteon in Elderly People
This study has been completed.
Sponsored by: Takeda Global Research & Development Center, Inc.
Information provided by: Takeda Global Research & Development Center, Inc.
ClinicalTrials.gov Identifier: NCT00568789
  Purpose

This is a crossover study of ramelteon 8 mg and zolpidem 10 mg compared with placebo in elderly patients with primary insomnia. Each subject is to receive a treatment sequence of all three treatments, randomized to different order; each treatment is for 1 day, with a washout period between each treatment. This study is designed to investigate the effects of ramelteon on balance, mobility, and memory impairment after middle-of-the-night awakening following bedtime dosing.

Primary Outcome Measures:
  • To evaluate the effect of ramelteon on balance compared to placebo using zolpidem as a reference in healthy elderly subjects following a nighttime awakening. [ Time Frame: 5 Weeks Total ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To evaluate the effects of ramelteon on mobility. [ Time Frame: 5 Weeks Total ] [ Designated as safety issue: No ]
  • To evaluate the effects of ramelteon on memory functions. [ Time Frame: 5 Weeks Total ] [ Designated as safety issue: No ]
  • To evaluate the safety and tolerability of ramelteon. [ Time Frame: 5 Weeks Total ] [ Designated as safety issue: Yes ]

Arms Assigned Interventions
1: Experimental Drug: ramelteon
8 mg ramelteon tablet, orally, one night only
Drug: zolpidem
10 mg zolpidem tablet, orally, one night only
Drug: placebo
Placebo tablet, orally, one night only

Detailed Description:

Subjects participating in this study will be randomized to receive in different order a single dose of 8 mg of ramelteon, 10 mg of zolpidem and a placebo over three overnight stays at a research facility. The 3 treatment days are each separated by a 5 to 10 days.

Subjects will be given their assigned treatment as a single dose on the night of treatment, awakened 2 hours after dosing, and tested for mobility, balance, immediate memory recall, and delayed memory recall. Safety is to be measured through the record of adverse events, vital sign measurements, clinical laboratory tests, and electrocardiogram tracing.
