NCT00094887
This study will examine whether nitric oxide (NO) gas can reduce the time it takes for pain to go away in patients who are in sickle cell crisis. NO is important in regulating blood vessel dilation, and consequently, blood flow. The gas is continuously produced by cells that line the blood vessels. It is also transported from the lungs by hemoglobin in red blood cells. Patients 10 years of age or older with sickle cell disease (known SS, S-beta-thalassemia or other blood problems causing sickle cell disease) may be eligible for this study. Patients whose disease is due to hemoglobin (Hgb) SC are excluded. Candidates are screened with blood tests and a chest x-ray to look at the lungs and heart. Participants are admitted to the hospital in a pain crisis. They are evaluated and then randomly assigned to receive one of two treatments: 1) standard treatment plus NO, or 2) standard treatment plus placebo. The placebo used in this study is nitrogen, a gas that makes up most of the air we breathe and is not known to help in sickle cell disease. For the first 8 hours of the study, patients receive placebo or NO through a facemask. The mask may be taken off for 5 minutes every hour and for not more than 20 minutes to eat a meal. After the first 8 hours, the gas is delivered through a nasal cannula (small plastic tubing that rests under the nose) that may be taken off only while showering or using the restroom. Patients are questioned about the severity of their pain when they start the study and then every few hours while they are in the hospital. Their vital signs (temperature, breathing rate, and blood pressure) and medicines are checked. Patients will breathe the gas for a maximum of 3 days, but will stay hospitalized until the patient feels well enough to go home. Patients are followed up about 1 month after starting the study by a return visit to the hospital or by a phone call.
NCT00656305
A Pivotal Study to Evaluate the Effectiveness and Safety of ExAblate Treatment of Metastatic Bone and Multiple Myeloma Tumors for the Palliation of Pain in Patients Who are not Candidates for Radiation Therapy
NCT01158651
The purpose of this research study is to learn if the study drug RAD001 can shrink or slow the growth of low-grade gliomas in children with Neurofibromatosis type 1 (NF1). Additionally, the safety of RAD001 will be studied. The study drug, RAD001, is a drug that may act directly on tumor cells by preventing tumor cell growth and development. RAD001 has been studied in participants with various types of cancer as a single agent (a drug that is used alone to treat the cancer) or in combination with a number of well known anticancer therapies. Information from these research studies suggests that RAD001 may help to shrink or slow the growth of low-grade gliomas. In this research study, the investigators are looking to see the response of RAD001 in children with low-grade gliomas and NF1 that have either not responded to treatment or have come back after treatment. We are also looking for the highest dose of RAD001 that can be given safely in this patient population.
NCT04007588
This research study is studying different immunotherapy regimens as a possible treatment for stage III or IV resectable melanoma.
NCT02764151
This study will evaluate the safety and tolerability of increasing doses of PF-06840003 in patients with malignant gliomas.
NCT01914939
This 3-year study is a trial of cognitive behavioral therapy (CBT), with or without oxytocin (OT) augmentation, in young adults with autism spectrum disorders. Participants will be randomly assigned to receive either a social skills-focused CBT intervention or a stress management/relaxation training CBT intervention. Participants will also be randomized to receive either a) intranasal oxytocin or b) a placebo drug, prior to the psychotherapy. The design of the study will enable examination of the efficacy of CBT for young adults with autism spectrum disorders. The design of the study will also allow examination of whether oxytocin enhances the efficacy of CBT. The investigators will perform functional (fMRI) and structural (MRI) imaging with all participants prior to treatment. This will enable examination of the relations between measures of brain function and structure, and improvements in target symptoms over the course of treatment. The aim is to discover whether there are neural characteristics that can identify which participants with autism spectrum disorders are most likely to respond to CBT interventions and/or oxytocin treatment.
NCT03096314
Vitamin D deficiency is a common, potentially reversible contributor to morbidity and mortality among critically ill patients. We conducted a randomized, double-blind, placebo-controlled, phase 3 trial of early vitamin D3 supplementation in critically ill, vitamin D-deficient patients who were at high risk for death. Patients screened as vitamin D deficient (\<20 ng/mL) were randomized. Randomization occurred within 12 hours after the decision to admit the patient to an intensive care unit. Eligible patients received a single enteral dose of 540,000 IU of vitamin D3 or matched placebo. The primary end point was 90-day all-cause, all-location mortality.
NCT02196831
Liver disease is one of the leading co-morbidities of human immunodeficiency virus (HIV) infection, and nonalcoholic fatty liver disease (NAFLD) is present in approximately 30-40% of patients with HIV infection. Nonalcoholic steatohepatitis (NASH) is a more severe form of NAFLD in which increased liver fat is also accompanied by inflammation, cellular damage, and fibrosis. NAFLD is most prevalent in patients who also have increased visceral adiposity, and our group has previously shown that HIV-infected individuals with increased visceral adiposity generally have decreased growth hormone secretion. Tesamorelin is a growth hormone releasing hormone (GHRH) analogue that increases endogenous growth hormone secretion. Tesamorelin is FDA-approved for the reduction of visceral fat in HIV-infected individuals. In a previous study, treatment with tesamorelin in HIV-infected individuals selected for abdominal adiposity reduced liver fat. The current study is designed to test the effect of tesamorelin on liver fat and steatohepatitis in HIV-infected individuals who have NAFLD. The investigators hypothesize that tesamorelin will reduce liver fat and will also ameliorate the inflammation, fibrosis, and hepatocellular damage seen in conjunction with NASH.
NCT03644771
Patients with proteinuria to start treatment with Acthar and watch a variety of clinical parameters with a goal of decreasing proteinuria between 50-100% over a period of nine months with every 3 months increasing the dose of medication until a decrease of either 50- 100 % of protein excretion is achieved. In addition addition podocyte function will be assessed monthly by measuring suPar levels, tnf alpha, podocyte/creatinine levels as well as podocyte function studies.
NCT02117024

The anticipated duration of this study is approximately 4.5 years.
NCT01484275
The purpose of this study is to evaluate the safety and efficacy of siltuximab compared with placebo (an inactive substance that is compared with a drug to test whether the drug has a real effect in a clinical trial) in patients with high-risk smoldering multiple myeloma (SMM).
NCT01097330
Implantable Cardioverter Defibrillators (ICDs) provide a shock or pacing therapy to bring back a normal heart beat when a patient experiences a dangerous abnormal heart rhythm such as ventricular tachycardia (VT). ICDs are very successful in bringing back a normal heart beat when VT occurs, but they do not prevent further dangerous heart rhythms from occurring. This study is designed to determine the best way to manage patients who have an ICD and who continue to have episodes of VT. There are two methods for treatment the VT: 1) Ablation, and 2) Medication. An ablation procedure involves placing a flexible catheter (insulated wire) in the groin area and threading it into the heart. After the doctor has located the affected area responsible for the VT, radiofrequency energy is delivered by the power generator through the catheter to the inside of the heart. The radiofrequency energy ablates (burns) a small area of the heart tissue thought to cause the VT. A medication called Amiodarone is an "anti-arrhythmic" prescribed to prevent abnormal heart rhythms from recurring. The purpose of this study is to compare these two different methods for treating VT. Treatment with ablation and amiodarone are both considered the standard of care for patients with VT but they have not been compared directly in a study like this before.
NCT03673358
Psychological factors such as stress, distress, anxiety, depression, and poor coping strategies may be associated with ongoing pain following injuries such as fractures. To study this relationship, patients will undergo cognitive behavioural therapy (CBT) which is designed to modify such thoughts with the goal of reducing ongoing pain and improving quality of life. The goal of this study is to determine if CBT, versus usual care, reduces the prevalence of moderate to severe persistent post-surgical pain (PPSP) over 12-months post-fracture
NCT00005803
This phase I/II trial studies how well autologous stem cell transplant followed by donor stem cell transplant works in treating patients with lymphoma that has returned or does not respond to treatment. Peripheral blood stem cell transplant using stem cells from the patient or a donor may be able to replace immune cells that were destroyed by chemotherapy used to kill cancer cells. The donated stem cells may also help destroy any remaining cancer cells (graft-versus-tumor effect).
NCT00089011
This phase II trial studies how well tacrolimus and mycophenolate mofetil works in preventing graft-versus-host disease in patients who have undergone total-body irradiation (TBI) with or without fludarabine phosphate followed by donor peripheral blood stem cell transplant for hematologic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate, and TBI before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune system and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving tacrolimus and mycophenolate mofetil after the transplant may stop this from happening.
NCT02892019
This study is designed to explore lung function effects of two doses of indacaterol acetate, 75 μg and 150 μg, in pediatric asthma patients 6-11 years old, and to compare the systemic exposure to indacaterol in plasma with historical data in adults, to identify an appropriate dose to Phase III evaluation.
