NCT01261390
Moderate to severe sleep apnea (a high number of breathing pauses on a sleep study) is a common health problem that is often associated with loud snoring and sleepiness.The medical term for this problem is obstructive sleep apnea (OSA). People with OSA often have an increased risk for developing heart disease or may already have a diagnosis of heart disease. A clinical research study is being conducted at Brigham and Women's Hospital (BWH) and Beth Israel Deaconess Medical Center (BIDMC) to compare the effects of continuous positive airway pressure (CPAP) to conservative medical therapy with participation in one of four groups: 1. Active-PAP Therapy Group (Active-Beh or Active+Beh): Will receive standard medical treatment for sleep apnea with active-PAP. Participants will be randomized to either: 1. Active-Pap with respiratory therapist visits only 2. Active-Pap with respiratory therapist visits and cognitive behavioral therapist visits. 2. Alternative PAP Group (Sham): Will receive lower air delivery level than active-PAP therapy group. Will also have meetings with respiratory therapist. 3. Conservative Medical Therapy Group (CMT)\*: Will receive a free supply of nasal strips for the duration of their treatment period (either 6 months or 12 months) and follow healthy sleep hygiene guidelines for how to change sleep habits to minimize incidences of apneas (breathing disturbances during sleep). Frequent follow-up support with research coordinator. A sleep doctor or cardiologist will have indicated that a potential participant is an appropriate candidate to receive PAP or CMT as acceptable approaches to treat his/her sleep apnea. Participants will be recruited between the ages of 45-75 years who have diagnosed heart disease or between 55-75 years for those who have risk factors for developing heart disease. This is a 6-12 month study\*\* to evaluate alternative ways to address the potential for OSA treatment to reduce heart disease and to identify those features that would strengthen a later, large-scale randomized controlled trial. We will test the hypothesis that active treatment for OSA with CPAP reduces CVD morbidity and mortality. \*All randomized participants will be given conservative medical therapy (CMT). \*\*For those randomized after December 31, 2012, follow-up assessment will only be 6 months long
NCT01975909
Spinocerebellar Ataxia (SCA) refers to a family of genetic diseases that cause progressive problems with gait and balance, as well as other debilitating symptoms. This is a randomized controlled pilot study to test a novel therapeutic intervention that uses noninvasive magnetic brain stimulation to improve functional outcomes in patients with SCA. The study will include quantitative evaluations of gait, balance, and brain physiology to examine possible objective end-points for a future, larger multi-site clinical trial. The investigators anticipate that patients receiving the real intervention will show a functional gain.
NCT01323920
A common problem after stem cell transplant is graft-versus-host-disease (GVHD). GVHD is a complication of transplantation where the donor graft attacks and damages some of your tissues. After stem cell transplant, all patients receive prophylactic medications against GVHD. In this research study, we are studying the safety and effectiveness of a bortezomib based GVHD prophylaxic drug combination in participants after myeloablative allogeneic stem call transplantation from a matched unrelated donor, mismatched related or unrelated donor.
NCT01430403
The purpose of this trial is to compare the efficacy of 4 to 5 months of three treatments - omalizumab, corticosteroid therapy boost, and placebo - in reducing fall exacerbations in inner-city children and adolescents with allergic persistent asthma when initiated approximately 4 -6 weeks prior to the start of the first day of each participant's school year.
NCT00513474
RATIONALE: Rasburicase may be an effective treatment for graft-versus-host disease caused by a donor stem cell transplant. PURPOSE: This clinical trial is studying how well rasburicase works in preventing graft-versus-host disease in patients with hematologic cancer or other disease undergoing donor stem cell transplant.
NCT00955266
Successful heart surgery requires the resumption of a strong beating heart prior to separation from the heart and lung machine. There are different ways to do this. At this hospital, the surgical team usually gives calcium to people when they come off of the heart and lung machine because some doctors believe that calcium can "jump start" the heart. Not every hospital does this. Some people think that calcium may have a side effect of making the heart more stiff. Stiff hearts do not beat as well or receive as much blood to tissues as non-stiff hearts. If calcium makes the heart stiff, then doctors may have to use other medicines to support the heart in the operating room and the intensive care unit. This may ultimately lead to poorer outcomes including a longer stay in the intensive care unit and in the hospital. This study is being performed to find out if calcium has the side effect of making the heart more stiff. This study compares calcium to placebo. The placebo looks exactly like the calcium, but it contains no calcium. During this study patients may receive placebo instead of calcium. Neither the doctor nor the study team will know which drug the subject will receive.
NCT01529502
The purpose of this study is to determine whether storage time affects how human body responds to autologous blood transfusion. An autologous blood transfusion is when a person donates blood and then receives that same blood back in the transfusion. We also want to find out if in this situation inhaled nitric oxide can help to prevent the potential reduction of vasodilation capacity. Vasodilation capacity is the ability of the blood vessel to widen when needed.
NCT00814502
The purpose of this research study is to compare the effectiveness of Zolpidem CR to that of placebo in improving sleep efficiency in people with dementia admitted to the hospital because of their symptoms. You can participate in this study if you have dementia of the Alzheimer's type or vascular dementia. This study involves placebo; a placebo is a tablet that looks exactly like Zolpidem CR, the study drug, but contains no active study drug. We will use placebos to see if the study results are due to the study drug or due to other reasons. Zolpidem CR is also called Ambien CR and is widely available by prescription. Zolpidem CR is approved by the U.S. Food and Drug Administration (FDA) for the short-term treatment of insomnia (trouble falling or staying asleep).
NCT02120001
The purpose of this study is to test the efficacy of a novel cleaning device in keeping silver-coated endotracheal tubes free from bacterial colonization.

NCT01868061
This randomized, multicenter, double-blind, placebo-controlled, parallel-group study will evaluate the efficacy and safety of lebrikizumab in participants with asthma whose disease remains uncontrolled despite daily treatment with inhaled corticosteroid (ICS) therapy and at least one second controller medication. Participants will be randomized in 1:1:1 ratio to receive double-blind treatment with either lebrikizumab ("high" or "low") or placebo, administered as subcutaneous (SC) injection every 4 weeks for 52 weeks, in addition to their standard-of-care therapy. This will be followed by a 52-week double-blind active treatment extension. Participants who were assigned to placebo during the placebo-controlled period of the trial will be re-randomized at Week 52 to receive blinded SC lebrikizumab 37.5 milligrams (mg) or 125 mg every 4 weeks from Weeks 53 to 104. The anticipated time on study treatment is 104 weeks. After study treatment, all participants will complete a 20-week safety follow-up.

NCT01987492
This randomized, multicenter, double-blind, placebo-controlled, parallel-group study will evaluate the efficacy of lebrikizumab compared with placebo, as measured by the ability of participants to achieve lower daily doses of OCS, among those with severe corticosteroid-dependent asthma. Prednisone/prednisolone will be the OCS therapy prescribed. Participants will be randomized to receive lebrikizumab or matching placebo for 44 weeks in a double-blind, placebo-controlled (DBPC) period. Those who complete the 44-week period may continue into a 32-week active treatment extension (ATE) period, during which all participants will receive lebrikizumab treatment. Following completion of the ATE period, participants who have both tolerated and derived benefit from treatment with lebrikizumab may continue their lebrikizumab treatment into a long-term extension (LTE) period. Participants will transition to 24 weeks of safety follow-up upon discontinuation of study drug.
