NCT00683696
The EchoCRT trial evaluates the effects of Cardiac Resynchronization Therapy (CRT) on mortality and morbidity of subjects with heart failure due to left ventricular systolic dysfunction, already receiving optimized HF medication, with a narrow QRS width (\< 130 ms) and echocardiographic evidence of ventricular dyssynchrony.
NCT01970631
The objectives of this research are to conduct a proof of concept randomized controlled trial with 200 patients undergoing primary total knee replacement (TKR) at Brigham and Women's Hospital (BWH). The trial will compare levels of physical activity in subjects in the behavioral and economic interventions versus "Usual Care" post TKR.
NCT03011957

NCT01772823
Approximately 200 HIV-uninfected young men who have sex with men (YMSM) at high risk of acquiring HIV infection, ages 18-22 years, inclusive, will be recruited across all participating Adolescent Medicine Trials Units (AMTU). The behavioral intervention will be assigned at the level of the site, which include Many Men, Many Voices (3MV) and Personalized Cognitive Counseling (PCC). Subjects will first complete the behavioral intervention offered at their respective site and then be provided with open label emtricitabine (FTC)/tenofovir (TDF) (Truvada®) as PrEP. Behavioral and biomedical data will be collected at baseline and 0, 4, 8, 12, 24, 36 and 48 weeks. Any subjects who become HIV infected during the course of the study will be discontinued from the study agent and followed for an additional 24 weeks after the study visit at which HIV infection is confirmed. Those subjects who meet specific bone or renal criteria at the Week 48 visit or the 24-Week HIV Seropositive visit will be followed for an additional 48 weeks in the Extension Phase to monitor longer-term outcomes of potential concerns.
NCT00851253
RATIONALE: Stereotactic radiosurgery may be able to send x-rays directly to the tumor and cause less damage to normal tissue. PURPOSE: This phase I trial is studying the side effects of stereotactic radiosurgery in treating patients with locally advanced or recurrent head and neck cancer.
NCT01128959
The purpose of this study is to assess the safety and tolerability of intravenous (IV) carbamazepine (CBZ) administered as multiple 15 minute infusions and a single 5 minute infusion to adult patients with epilepsy on stable higher doses of oral CBZ.
NCT00435942
The purpose of this study is to evaluate the safety and efficacy of the Relay thoracic stent-graft system to treat thoracic aortic aneurysms. Efficacy will be evaluated by the device-related adverse event rate of endovascular repair (via Relay Thoracic Stent-Graft) through 1-year. Safety will be evaluated by comparing major adverse events through 1-year in subjects treated with the Relay Thoracic Stent-Graft to those who underwent surgical repair. Long term follow-up is conducted through 5 years.
NCT02230332
Beta-2-agonists are effective in reducing airway narrowing in asthma and protecting against stimuli that produce bronchoconstriction. The combination of long-acting beta agonists (LABA) and inhaled corticosteroids (ICS) has become the most commonly used asthma controller medication class in the United States, but unfortunately, even when LABAs are added to ICS and used regularly, 58-81% of patients with asthma fail to achieve total control. Regular use of beta-agonists, both short and long-acting, reduces the ability of these agents to protect against the airway narrowing that occurs in asthma in response to bronchoconstrictor stimuli. We refer to this reduced effect as loss of bronchoprotection. In this proof of concept trial we aim to determine if alendronate, which diminishes beta-2 adrenergic receptor internalization, can reduce the loss of bronchoprotection that occurs with regular use of LABAs, even when used in combination with ICS.
NCT01472627
The purpose of this study is to better understand what effects Bortezomib, a drug used for multiple myeloma therapy, has on the immune system.
NCT03003689
Dental bacterial plaque is the most frequent modifiable finding in patients with periodontal (gum) diseases. Many studies have provided evidence that mechanical removal of dental plaque is critical for improving the periodontal health. The standard initial treatment of periodontitis (gum disease) is to remove plaque and calculus form the teeth and root structures using sclaing and root planing (SRP). Typically hand instruments and an ultrasonic scaler are used for SRP While this method removes some of the bacteria that leads to periodontitis, microorganisms are not completely eliminated through SRP. Studies have shown that after 3 months, the bacteria initially present prior to scaling and root planing had recolonized. In order to prevent recurrence of periodontitis, it is recommended that oral bacteria be kept at low levels. When used at the proper wave length, dental lasers have been shown to effectively removes calculus, without damaging surrounding tissue. The Er:YAG laser has been FDA-approved for the use of scaling and root planing in Dentistry. While studies on the Er:YAG laser have shown that it is effective in removing calculus and preserving the tooth root structure, there is no consensus of the level of calculus removal. The Er:YAG laser may also be more effective in removing microbial bacteria than SRP with hand instruments and ultrasonic scaler. The purpose of this study is to evaluate the effectiveness of the Er:YAG laser, as an adjunct to scaling and root planing, in removing microbial bacteria. Participants with chronic periodontitis will be randomized to have one quadrant undergo scaling and root planing using hand instruments and ultrasonic scaler alone, while a second quadrant will receive the same treatment, with the addition of the Er:YAG laser. Outcomes studies will be traditional periodontal clinical parameters at 6 weeks and 3 months after treatment. Microbial cultures will be performed at baseline and 3 months to compare survival and re-population by periodontal microorganisms.

NCT01449929
This study will be conducted in approximately 468 HIV-1 infected antiretroviral therapy (ART)-naïve subjects. Subjects will be randomized 1:1 to receive dolutegravir (DTG) 50 mg once daily (approximately 234 subjects) or darunavir/ritonavir (DRV/r) 800 mg/100 mg once daily (approximately 234 subjects), each in combination with fixed-dose dual nucleoside reverse transriptase inhibitor (NRTI) therapy (either abacavir/lamivudine (ABC/3TC) or tenofovir/emtricitabine (TDF/FTC). Subjects will be stratified by screening HIV-1 RNA and background NRTI selection. The primary analysis will take place after the last subject completes 48 weeks on therapy; an additional analysis will be conducted after the last subject completes Week 96 on study.
NCT03094468
The aim of this phase III study is to establish the efficacy and safety of P-3058 (terbinafine 10% nail solution) topically administered once weekly in patients with onychomycosis in comparison to the Vehicle in a double-blind fashion. The overall treatment period will be of 48 weeks.
NCT00404768
Pre-Term Labor (prior to 37 weeks gestation) is the largest single cause of infant morbidity and mortality and is frequently associated with long-term disability. Oxytocin is a hormone produced by the body during labor. GSK221149A is an experimental drug that will be used to block the effects of oxytocin, and therefore pause or prevent contractions. In this study, patients with preterm labor will be given an intravenous infusion of GSK221149A over approximately 12 hours followed by an oral tablet in Parts A and B. In part C of this study, patients with preterm labor will be give an intravenous infusion of GSK221149A over approximately 48 hours. The use of a rescue tocolytic is allowed in the study.
NCT02427217
This is a multicenter, non interventional, retrospective cohort study with a prospective, observational follow-up component to investigate the safety and efficacy of FCH use in subjects with congenital fibrinogen deficiency. Data will be collected on the safety and efficacy of FCH as used for the treatment of acute bleeding episodes, routine prophylaxis and perioperative bleeding in these subjects. All subjects have received FCH and may continue to receive FCH at the discretion of the treating physician / Primary Investigator according to the standard of care at the participating study site.
NCT00036647

OSI-774 is a new type of drug under evaluation called an epidermal growth factor receptor (EGFR). OSI-774 is an investigational drug that has not yet been approved by the U.S. Food and Drug Administration (FDA).
