NCT00753623

Brief Summary

This proposal is to conduct a double-blinded, randomized, placebo-controlled, crossover clinical study to examine the hypothesis that ramelteon would reduce pain score and improve functional status in subjects with neuropathic pain.

Outcome Measures

Primary Outcomes (1)

  • Difference in Visual Analog Scale (VAS) for Pain (0-10) Between Treatments

    Subjects were asked to rate their pain the VAS with 0 being no pain and 10 being the worst pain they can imagine. The VAS scores were compared between the baseline and after a period of treatment. A negative number indicates an improvement in pain from baseline score.

    VAS score at baseline and after the treatment period

Study Arms (2)

Ramelteon first, placebo second

ACTIVE COMPARATOR

In a crossover design, a subject will be first assigned to the ramelteon arm and then switched over to the placebo arm. As this is a double-blind study, neither the subject nor the study staff will know which intervention the subject is randomly assigned. The ramelteon dose is 8mg once a night.The ramelteon and placebo will be blinded by the central pharmacy. The subject is randomly assigned to first receive either ramelteon or placebo. The first intervention will be 14 days long. There is a 7 day washout period, and then the subject is assigned to the opposite intervention. The second intervention will be 14 days long.

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subject will be between ages 18 to 65 years.
  • Subject has not been on ramelteon for at least one month.
  • Subject agrees to make no change in his/her current pain medications during the entire study period (5 weeks). This requirement will ensure that valid comparisons of primary and secondary measures can be made before and after the study.
  • Subject has a VAS pain score of 5 or above at the beginning of the study.
  • Subject has had a neuropathic pain condition as listed above for at least three months. This requirement is to avoid clinical uncertainty from an unstable pain condition and to minimize the study variation.
  • Female subjects of childbearing potential must have a negative urine pregnancy test at the initial visit.

You may not qualify if:

  • Subject has moderate to severe liver impairment.
  • Subject has Liver Function Tests (LFT's) \>1.5X normal.
  • Subject has a history of renal impairment.
  • Subject has moderate or severe cardiac or pulmonary disease including a base line oxygen saturation of less than 95% on room air or any requirement for supplemental oxygen.
  • Subject has a history of glaucoma.
  • Subject has obstructive sleep apnea.
  • Subject is taking medications for sleep disorders including insomnia.
  • Subject has a major psychiatric disorder (major depression requiring a recent hospitalization within three months prior to the study; bipolar disorder; schizophrenia; psychotic disorders; substance abuse).
  • Subject has a history of dementia or delirium.
  • Subject has a history of falls.
  • Subject is pregnant or lactating.
  • Subject is using an illicit drug detected by a screening test.
  • Subject is currently taking Fluvoxamine.
  • Subject has been taking Ketoconazole in the past two weeks.
  • Subject has known hypersensitivity to ramelteon.
  • +2 more criteria
