NCT00880919
The Primary objective of this study is to evaluate Seroquel XR in the treatment of borderline personality disorder (BPD). As in many initial randomized control trials, the study will be of relatively short duration - 8 weeks - to assess effectiveness and safety while maximizing retention. The specific aim is to determine if Seroquel XR is superior to placebo. The primary outcome measure will be a statistically significant difference between Seroquel XR compared to placebo on the Zanarini Rating Scale for Borderline Personality Disorder (ZAN-BPD), an objective rating scale that addresses the severity of Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) symptoms of the illness. As there is the recent development of an extended release form of Seroquel (Seroquel XR) (Schulz et al. 2007), the new compound may offer several advantages in this study. Therefore, the hypothesis of this study is that both doses of Seroquel XR (see below) will be superior to placebo in an 8-week randomized trial as assessed by the ZAN-BPD. To achieve the Primary Objective of this study, two doses of Seroquel XR will be tested - 150 mg/d and 300 mg/d. Thus, the study will be able to assess the effect of Seroquel XR compared to placebo and to explore a dose effect.
NCT00776100
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Sometimes, after chemotherapy, the tumor may not need more treatment until it progresses. In this case, observation may be sufficient. It is not yet known whether radiation therapy is more effective than observation after chemotherapy in treating non-small cell lung cancer. PURPOSE: This randomized phase II trial is studying how well radiation therapy works compared with observation after chemotherapy in treating patients with stage IV non-small cell lung cancer.
NCT01240512
This is a randomized, double-blind, multicenter, 6-month follow-up trial of low (400 IU/day) versus high (4000 IU/day) dose vitamin D supplementation in individuals with pre- and early stage 1 hypertension and vitamin D deficiency. A total of 530 participants (265 participants per treatment arm) will be randomized between 3 sites. Approximately 2,250 participants will be screened between the 3 sites. Vital signs, 24-hour ambulatory blood pressure monitoring, clinical laboratory safety tests and adverse event assessments will be performed to evaluate the effectiveness of the two doses of vitamin D on blood pressure. Blood samples will be stored for future biomarker assessments. The total duration of the study is anticipated to be 18 months, assuming a 12 month enrollment period.
NCT01292928
The primary objective of this clinical study is to determine whether the Innova Stent System shows acceptable performance in long-term (12-month) safety rates and vessel patency when treating femoropopliteal lesions.
NCT00950885
Melatonin supplements have been reported to be an effective treatment for circadian rhythm sleep disorders, including shift work dyssomnia, jet-lag, delayed sleep phase syndrome, and sleep disruption suffered by many blind individuals. However, the mechanism(s) by which melatonin affects the timing of sleep are not well-understood. The purpose of this study is to determine if melatonin improves sleep and performance on a schedule simulating eastward travel. This study will provide information regarding the mechanism of action of melatonin that will be critical for the use of melatonin as a treatment for circadian rhythm sleep disorders.
NCT02524561
Combined estrogen and progestin therapy has been shown to increase mammographic density and incidence of breast cancer in randomized trials. The investigators propose to examine the effects of now commonly used low-dose combined hormone therapy (HT) regimens on breast density, rates of abnormal mammogram, and circulating estrogens in the ongoing, already-funded Kronos Early Estrogen Prevention Study (KEEPS). KEEPS is a randomized clinical trial with a primary goal of examining the effects of low-dose transdermal versus oral estrogen combined with cyclic micronized progesterone on progression of subclinical atherosclerosis in recently menopausal women. Prior studies of low-dose HT have been of short duration and small size. By determining the effects of low-dose hormone therapy on the breast, the proposed ancillary study will add important information about the estimated balance of risks and benefits associated with low-dose HT and will help guide future research trials.
NCT00503698
This trial is conducted in Africa, Asia, Europe, North and South America and Oceania. The aim of the trial is to evaluate the effect of somatropin (human growth hormone) on survival (primary end-point; "time to death" and health related quality of life in adult patients on chronic haemodialysis.
NCT01468649
The objective of this Phase II study is to assess the diagnostic accuracy of sentinel lymph node (SLN) identification in patients with breast cancer using near-infrared (NIR) fluorescence optical imaging.
NCT01729871
The purpose of this exploratory study is to evaluate the safety of rivaroxaban and uninterrupted vitamin K antagonist (VKA) in adult participants with non-valvular atrial fibrillation (NVAF) who undergo catheter ablation as measured by post-procedure major bleeding events.
NCT01130142
Study IPI-926-03 is a Phase 1b/2 clinical trial to evaluate IPI 926 in combination with gemcitabine in patients with previously untreated metastatic pancreatic cancer. Phase 1b is designed as a dose escalation study. Once the maximum tolerated dose of IPI-926 in combination with gemcitabine is established in the Phase 1b portion of the study, the Phase 2 portion will commence. Phase 2 is designed as a randomized, double-blind (investigator/patient), placebo-controlled study. There is no cross-over option for patients in either arm of the Phase 2 (i.e., there is no option for patients receiving placebo to cross-over to IPI-926).
NCT00398840
This is an open label, dose escalation study of ARQ 171 administered via intravenous infusion (IVI) into a peripheral vein weekly. Patients with advanced solid tumors, who are refractory to available therapy or for whom no standard systemic therapy exists, will be enrolled.
NCT02004457
Engagement in primary care for People Living with HIV/AIDS (PLWHA) is a significant public health concern because reduced commitment to care puts PLWHA at risk for illness progression, death, and transmission of HIV to others. This project will develop a novel treatment, brief acceptance-based behavior therapy (ABBT), to promote self-acceptance of HIV status as a pathway to reducing engagement barriers. The clinical and public health impact of this project will be the development of a simple, low-cost, disseminable intervention that enhances longitudinal commitment to care so PLWHA can obtain effective medical treatments that will prolong survival and improve quality of life. We hypothesize that individuals randomized to brief ABBT will showed increased longitudinal attendance of primary care appointments.
NCT00914589
This trial is conducted in Canada, Asia, Europe and USA. The aim of this clinical trial is to investigate the effect and safety of rFXIII on transfusion needs in patients undergoing heart surgery.
NCT02981420
A youth's contact with the juvenile justice system represents an opportune moment for suicide screening and brief suicide intervention for indicated youth. This study will provide data on the novel implementation of an evidence-based brief suicide intervention, safety planning, administered by front-line juvenile court staff for suicidal court-involved non-incarcerated youth. Data will inform the dissemination and implementation of suicide brief interventions to be delivered by front-line staff at the time of mental health screening in the juvenile justice system. The proposed study is consistent with the NIMH Strategic Plan by testing an intervention for effectiveness in community settings (Strategy 3.3) and establishing a research-practice partnership to improve D\&I of evidence-based MH services (4.2). The unique service delivery by JJ court staff also supports the NIMH goals to develop innovative service delivery models (Strategy 4.3) as well as validate a MH intervention for an underserved population (Strategy 4.1). This proposal also addresses the Healthy People 2020 goals of reducing suicide attempts (MHMD-2).
