NCT00605683
Parkinson's disease is a major neurodegenerative disorder in which there is a progressive loss of nigrostriatal dopaminergic neurons. The understanding that PD is a syndrome of dopamine (DA) deficiency led to the introduction in the clinical practice of L-dopa, a precursor of DA that crosses the blood brain barrier, and also to the use of selective inhibitors of MAO B, the major DA metabolising enzyme in man. This is a double-blind, placebo-controlled, parallel-group, randomised, multi-centre, multi national, Phase III trial, comparing two doses of safinamide (50 and 100 mg p.o. q.a.m.) versus placebo as add-on therapy to a stable dose of a single dopamine agonist in subjects with early idiopathic Parkinson's Disease. The principal efficacy measure, i.e., change in mean value of UPDRS - Section III total score from baseline to endpoint, was chosen based on regulatory guidance and prior use in other trials in similar populations.
NCT00983853

NCT00046709
To find out if it is safe and effective to use smoked marijuana in combination with opioids to treat cancer pain. The study will evaluate whether smoked marijuana, when used with opioids, will have an effect on pain relief, and to see if marijuana reduces the side effects of opioids, which include nausea and/or vomiting.
NCT00305279

NCT00243893
The purpose of this pilot study is to investigate the use of minocycline and doxycycline as medical therapy for inoperable or partially treated arteriovenous malformations (AVMs) and giant aneurysms.
NCT00187629
The purpose of this study is to determine the effects of different amounts of phosphorus in the diet on hormones that control phosphorus and bone health both in men who are healthy and in ones who have moderate kidney disease.
NCT00086996
RATIONALE: Drugs used in chemotherapy, such as oxaliplatin and fluorouracil, work in different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Oxaliplatin and fluorouracil may make tumor cells more sensitive to radiation therapy and may kill more tumor cells. Giving chemotherapy and radiation therapy before surgery may shrink the tumor so that it can be removed. PURPOSE: This phase II trial is studying how well giving oxaliplatin together with fluorouracil and radiation therapy works in treating patients who are undergoing surgery for stage II or stage III cancer of the esophagus or gastroesophageal junction.
NCT00071201
This is a multi-center phase 3, open-label, parallel-group study designed to evaluate the efficacy, safety and pharmacokinetics of adefovir dipivoxil liquid suspension in patients with chronic hepatitis B and varying degrees of renal impairment.
NCT01292473
The study is a global Phase III, multicenter, randomized, double-blind, placebo-controlled, parallel-group study to evaluate the efficacy and safety of omalizumab administered subcutaneously as an add-on therapy for the treatment of adolescent and adult patients aged 12-75 who have been diagnosed with refractory CIU and who remain symptomatic despite standard-dosed H1 antihistamine treatment.
NCT01399580
Prospective, Randomized, Double-Blind, Parallel Design, Placebo-Controlled Multicenter Study. The study objectives are to evaluate efficacy and safety, including thoracic bioimpedance, of once daily administration of atrasentan tablets (high dose and low dose) compared to placebo in type 2 diabetic subjects with nephropathy who are receiving the maximum tolerated labeled daily dose of a RAS inhibitor.
NCT00066482
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase I trial to study the effect on the body of combining cyclophosphamide with cisplatin, etoposide, and bleomycin in treating children who have newly diagnosed malignant germ cell tumors that are not in the brain and gonads.
NCT01945190
Acupuncture is used extensively by patients worldwide for a variety of illnesses. While research is beginning to show effectiveness in clinical pain, the mechanisms underlying how these effects are evoked are poorly understood. Experimental models in healthy human volunteers can more closely control the variables of acupuncture needling and begin to separate out the relative contribution of specific components of needling and needle stimulation. By examining acupuncture's effects on experimental inflammatory models with well-characterized physiologic mechanisms, hypotheses can begin to be generated regarding how acupuncture produces its clinical effects. We propose to establish a model which could be used as a template to examine the individual components contributing to acupuncture's clinical effects on inflammation and pain. We hypothesize that acupuncture will have analgesic and anti-inflammatory effects on a ultraviolet B induced cutaneous lesion as well as a model of heat pain testing which activates central sensitization. Twenty healthy human volunteers will participate in a crossover study with active acupuncture and sham acupuncture interventions. They will be tested for their minimal erythemal dose (MED) to ultraviolet B exposure. An experimental lesion at 3x MED will be administered on the lower leg. Background information will be collected which could affect individuals' sensitivity to pain such as anxiety and depression, as well as their expectations regarding acupuncture treatment. The following day they will return for the first experimental day. A measurement with Laser Doppler will quantify the inflammation in the ultraviolet B lesion. Heat pain testing will be performed using a computer controlled thermode both on and off the ultraviolet B lesion. On-lesion testing will be for heat pain threshold. Off-lesion testing will examine temporal summation of heat pain. Next, a licensed acupuncturist will perform either true electroacupuncture or sham electroacupuncture in the region adjacent to the ultraviolet B lesion. Participants are blinded to the intervention, as is the examiner collecting data. Afterwards, Laser Doppler and heat pain testing will be repeated. The difference between pre-acupuncture and post-acupuncture measurements will represent the acupuncture -induced analgesic and anti-inflammatory effects. Participants will return for another ultraviolet B exposure adjacent to the first, and will receive whichever sham or true acupuncture intervention was not performed on the first study day.
NCT00363116

NCT01166425
Study Design This is the second study of a multiphase, multicenter trial that will comprehensively examine lithium in the treatment of pediatric participants with bipolar I disorder. In order to examine the treatment of bipolar disorder with lithium, this study will include four phases of treatment. The first phase, the Efficacy Phase, will include participants being randomized to either lithium or placebo for 8 weeks to determine the efficacy of lithium in the treatment of children and adolescents with bipolar I disorder. Once participants complete the Efficacy Phase, participants may be eligible to continue in the Long- Term Effectiveness Phase for a maximum of 24 weeks of lithium treatment. Subsequently, participants meeting response criteria during the Long-Term Effectiveness Phase will be eligible to continue in the Discontinuation Phase. During the Discontinuation Phase, participants will be randomized to either placebo or lithium treatment for up to 28 weeks. Finally, those participants who experience a mood relapse during the Discontinuation Phase will be enrolled in an Open Label Restabilization Phase and treated with lithium for up to 8 weeks.
