Filter by:The purpose of the study is to demonstrate the effect of Lyrica on Wake after sleep onset in subjects with fibromyalgia with sleep maintenance disturbance (on polysomnogram)
The purpose of this study is to compare the effectiveness of two talk therapies for OEF/OIF Veterans at the Michael J. Crescenz and the West Haven VA Medical Centers. Participants will randomly receive one of two individual treatments intended to improve the sleep disturbance and nightmares of returning Veterans.
The major goal of this project is to investigate established insomnia treatments in a schizophrenia population to see if the improved sleep leads to overall better quality of life. In addition, we hypothesize that the insomnia treatment may also lead to observed improvements in other symptoms associated with schizophrenia such as cognitive impairments, obesity, and negative symptoms.
RATIONALE: Acupuncture may help relieve muscle and bone pain caused by aromatase inhibitor therapy, such as letrozole, exemestane, and anastrozole. PURPOSE: This randomized phase II trial is studying acupuncture to see how well it works in reducing muscle and bone symptoms in women receiving letrozole, exemestane, or anastrozole for stage 0, stage I, stage II, or stage III breast cancer.
To investigate the long-term efficacy and safety of treatment with esmirtazapine (Org 50081, SCH 900265, MK-8265) compared to placebo, in participants with chronic primary insomnia. Primary efficacy variable is Total Sleep Time (TST).
We wish to study sleep architecture in patients with chronic orthostatic intolerance. We will test the null hypothesis that there is no difference in time during the various phases of sleep between patients and healthy control subjects.
This study was conducted to investigate the efficacy of treatment with Org 50081 (Esmirtazapine) compared to placebo in elderly participants with chronic primary insomnia. Primary efficacy variable is Wake time After Sleep Onset (WASO), averaged over all in-treatment time points and measured by polysomnography (PSG).
The current study is a 52-week safety study in elderly outpatients with chronic primary insomnia randomized to treatment with 1.5 mg or 3.0 mg of esmirtazapine (Org 50081, SCH 900265, MK-8265) to investigate the safety and tolerability of long-term treatment with esmirtazapine in elderly patients.
Background: Posttraumatic stress disorder (PTSD) is a debilitating and disabling mental disorder that afflicts at least 25% of Veterans who have suffered life-threatening war zone trauma. Trauma-related nightmares and sleep disturbance are among the most treatment-resistant PTSD symptoms in Veterans. Increased responsiveness to central nervous system (CNS) norepinephrine (NE) contributes to the pathophysiology of overall PTSD and treatment-resistant nighttime symptoms. Placebo-controlled pilot studies demonstrate that the generically available CNS-active alpha-1 adrenoreceptor antagonist prazosin substantially reduces PTSD trauma nightmares and sleep disturbance and improves global clinical status (sense of well being and ability to function) in Veterans. Objective: The primary objective is to demonstrate in a large multi-site placebo-controlled trial in Veterans with war zone trauma-induced PTSD that prazosin is efficacious for PTSD trauma nightmares, sleep disturbance, and global clinical status. A secondary objective is to demonstrate prazosin effectiveness for these outcome measures during clinically meaningful long-term (26 week) maintenance treatment of PTSD. The investigators will also address prazosin efficacy and long-term effectiveness for improving total PTSD symptoms, comorbid depression, quality of life, and physical functioning. Methods: This 26 week randomized double-blind placebo-controlled study is designed to demonstrate both short term efficacy and long term effectiveness of prazosin for PTSD. The research design encompasses a shorter-term, more tightly controlled efficacy component and a longer-term, more .real world. effectiveness component. Three hundred twenty-six Veterans with war zone -related PTSD and persistent trauma nightmares will be randomized 1:1 to prazosin or placebo. Study drug will be increased using a flexible dose titration schedule based on clinical response and adverse effects to an optimum maintenance dose (1-20 mg/day). During the first 10 weeks of the study, participants will be randomized to prazosin or placebo. Previous psychotropic medications and/or psychotherapy will be maintained constant. Short term efficacy will be determined during the first 10 weeks. During the remaining 16 weeks of the 26 week trial, subjects will continue to receive stable-dose double-blind prazosin or placebo, but will have the option to receive additional psychotropic medications and/or psychotherapeutic interventions, as needed, per the judgment of the study Clinician Prescriber. It is hypothesized that prazosin will remain more clinically effective than placebo at the end of the 26-week trial, demonstrating that prazosin adds benefit over-and-above other treatments that are naturalistically administered by providers in a .real world. clinical setting. Prazosin will be judged efficacious at 10 weeks if superior to placebo on all three primary outcome measures assessing trauma nightmares, sleep disturbance, and global clinical status: the Recurrent Distressing Dreams item of the Clinician Administered PTSD Scale (CAPS), the Pittsburgh Sleep Quality Index (PSQI), and the Clinical Global Impression of Change (CGIC). Secondary outcome measures will assess prazosin effects on total PTSD symptoms, depression, physical functioning, and quality of life. Adverse effects and cardiovascular measures, including supine and standing blood pressure (BP) and heart rate (HR) will be assessed.
The aim of this study is to develop information about the acute and residual effects of a new product being targeted to young adults. Using a double placebo-controlled 2 X 2 factorial model study design, we will compare the acute and residual effects on driving impairment of caffeinated alcohol, non-caffeinated alcohol, caffeinated placebo, and non-caffeinated placebo. Under the alcohol conditions, participants will receive sufficient alcoholic beverage to attain a blood alcohol concentration (BAC) of .12 g%. Participants will be 144 undergraduate and graduate students, and recent college graduates.
