Brief Summary:

The purpose of this study is to test two study drugs, one of which is temazepam (15mg) and one of which is a placebo (an inactive substance that looks just like the temazepam), to see if insomnia (trouble sleeping) can be reduced in patients with HIV infection. Placebos are given in research studies to try and make sure that subjects are responding to the effects of the study drug and not to other factors, like the attention they are receiving. If you decide to take part in this study, you will take 1 capsule of study drug every night approximately 30 minutes before bedtime for approximately 12 weeks.

This study is to test the study drug called temazepam for the treatment of insomnia (trouble sleeping) in patients with HIV infection. Temazepam has been approved by the FDA for the treatment of insomnia. However, because this study requires treatment for 12 weeks instead of the 7 to 10 days approved by the FDA, the use of temazepam is considered to be investigational in this study.

Arm Intervention/treatment
Active Comparator: temazepam
After screening, all subjects meeting entry criteria will be placed on the same single blind study drug treatment, asked to complete a daily sleep diary, and return one week later. After one week subjects randomized to temazepam will be given temazepam 15 mg for 12 weeks.
Drug: Temazepam
Temazepam 15 mg orally at bedtime

Placebo Comparator: Placebo
After screening, all subjects meeting entry criteria will be placed on the same single blind study drug treatment, asked to complete a daily sleep diary, and return one week later. After one week subjects randomized to placebo will be given placebo for 12 weeks.
Drug: Placebo



Primary Outcome Measures :
  1. Mean Change in the Insomnia Severity Index [ Time Frame: Randomization to final study visit, approximately 12 weeks ]
    Mean change in the total score of the Insomnia Severity Index from Randomization to Final Study Visit after 12 weeks of double blind, placebo controlled dosing. The Insomnia Severity Index (ISI), is a 7-item questionnaire on a Likhert scale (0-4) assessing sleep initiation, sleep maintenance, satisfaction/distress over sleep problems, and daytime dysfunction. Responses to each item are summed to obtain a total score to determine the severity of insomnia. The total score can range from 0 to 28 with higher scores indicating greater insomnia severity.


Secondary Outcome Measures :
  1. Mean Change in Self Reported Total Sleep Time [ Time Frame: Randomization to final study visit, approximately 12 weeks ]
    Mean change in self reported Total Sleep Time from Randomization to Final Study Visit in the placebo-controlled phase.

  2. Mean Change in Self-reported Total Sleep Time [ Time Frame: Randomization to the end of the open label phase, approximately 1 week ]
    Mean change in self-reported total sleep time from randomization to the end of the open label phase

  3. Mean Change in Piper Fatigue Score [ Time Frame: Baseline, week 12 ]
    A multidimensional scale for measuring fatigue, whose validity and reliability have been established across many patient populations including cancer patients, HIV, pregnancy, and myocardial infarction. There are 22 questions, in 3 subscales that measure behavioral, affective meaning, sensory and cognitive/mood aspects of fatigue, each scored on an 11-point likhert scale with a score of 0-10, 0 indicating no fatigue and 10 indicating the most severe fatigue. The Piper Fatigue Scale can range from 0 to 220 with higher scores indicating greater fatigue.

  4. Mean Change in the Hospital Anxiety and Depression Scale - Anxiety (HADS-A) [ Time Frame: Baseline, week 12 ]
    A scale designed to detect states of anxiety and depression in the setting of an outpatient clinic, that consists of 2 sets: the HADS-A (Anxiety) and HADS-D (Depression). This is a series of 7 questions in each set (for a total of 14), assessed on a scale from 0-4, 0 being the response that indicates the least anxiety or depression, and 4 the most. Separate scores are calculated for anxiety and depression and a score (ranging from 0 to 21) is obtained for each subscale. The higher the score, the more severe the anxiety or depression.

  5. Mean Change in the Distress Thermometer [ Time Frame: Baseline, week 12 ]
    A clinical tool that has been validated widely especially in cancer patients, to detect clinically significant emotional distress. This is a one-item scale that asks participants to rate their distress on scale from 0-100. Lower scores represent less distress and higher scores indicate greater distress.

  6. Mean Change in the Hospital Anxiety and Depression Scale - Depression (HADS-D) [ Time Frame: Baseline, week 12 ]
    A scale designed to detect states of anxiety and depression in the setting of an outpatient clinic, that consists of 2 sets: the HADS-A (Anxiety) and HADS-D (Depression). This is a series of 7 questions in each set (for a total of 14), assessed on a scale from 0-4, 0 being the response that indicates the least anxiety or depression, and 4 the most. Separate scores are calculated for anxiety and depression and a score (ranging from 0 to 21) is obtained for each subscale. The higher the score, the more severe the anxiety or depression.
