There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Prospective, randomized, multi-center, controlled study for patients undergoing open rotator cuff repair. Patients are stratified based on tear size to one of three groups. Each group is then randomized 1:1 to either repair with OrthoADAPT or repair without OrthoADAPT.
The combination of capecitabine and cetuximab as first-line therapy will result in improved progression free survival compared to single agent capecitabine in patients with KRAS wild type colorectal cancer. Patients who are not able or willing to take Oxaliplatin/Irinotecan combination therapy are eligible for this study.
The primary objective of this study is to assess the ability of epoetin alfa to raise hemoglobin (Hb) levels in elderly outpatients with unexplained anemia. The secondary objectives of this study are to assess the ability of epoetin alfa to improve physical function; cognitive function; and quality of life, and to assess the safety of epoetin alfa in the study population.
High Blood Pressure or Hypertension is one of the main causes of stroke, heart disease, heart attack and kidney disease. Traditionally physicians use diet and lifestyles change and medications to control patient's blood pressure. There are however, some patients whose blood pressures are difficult to control and their blood pressure remains elevated despite multiple medications. When blood pressure remains above goal (greater then 140/90 or greater then 130/80 mmHg in patients with diabetes or kidney disease) despite 3 or more blood pressure medications, the investigators call it "Resistant Hypertension". Enhanced External Counterpulsation (EECP) is a new method of treatment currently used in people with heart disease and chest pain. EECP therapy uses three sets of balloon like cuffs that are wrapped to the calves, lower thighs, and upper thighs. These cuffs inflate and deflate with every heart beat, causing increased blood return to the heart and better blood flow. It has also been found to improve the function of endothelial cells, a type of cells that lines the wall of blood vessel through out the body which helps to regulate and maintain blood pressure. This leads us to believe that EECP therapy, although not used at present for treating patients with Resistant Hypertension, may be useful in decreasing blood pressure.
The purpose of this study is to assess the mechanism of action of the Unite Biomatrix and compare its performance with the standard of care, compression therapy alone for the treatment of venous leg ulcers.
This is a multi-center study designed to assess the accuracy of Pima™ CD4 Test to enumerate CD4+ T-cells in whole blood over the measurement range expected for the intended population. The Pima CD4 Test consists of the Pima™ CD4 cartridge and Pima™ Analyzer to identify and determine the absolute counts of mature helper (CD3+/CD4+) T-lymphocytes in whole blood.
The purpose of this study is to determine how well different treatments for acquired lymphedema work. The study will compare 5 different non-invasive treatments for acquired lymphedema of the arm to see which treats lymphedema best.
The purpose of this study is to compare the clinical and radiographic outcomes of a randomized, consecutive series of adult patients, with an acquired flatfoot, treated with a lateral column lengthening using an allograft bone wedge versus a titanium porous metal implant (Biofoam, Wright Medical). Null hypothesis: At six months postoperatively, there is no difference in the degree of correction as measured by the talonavicular coverage angle between patients randomized to allograft and Biofoam. Alternative hypothesis: At six months postoperatively, the degree of correction as measured by the talonavicular coverage angle will be less in patients randomized to allograft than the degree of correction in patients randomized to Biofoam.
The primary purpose of this study is to determine if it is effective to take samples of fluid from the patient's brain tumor with a microdialysis catheter for Torisel measurement. The investigators are also doing it to learn if it is safe to do so. The investigators will use these samples to measure how much Torisel reaches the patient's brain tumor. The use of the microdialysis catheter to collect brain fluid is an FDA approved method. This catheter is already being used in patients who have sustained severe brain trauma from head injuries. The catheter itself is smaller in size than the standard needle that will be used to take the patient's biopsy. To obtain additional information Torisel will also be measured at the same time in the patient's cerebral spinal fluid by taking it from a catheter placed in the patient's cerebral spinal fluid producing spaces in their brain and in their blood from a catheter in one of their vessels.
The investigators hypothesize that a 3 month course of vitamin D supplementation to treat 25(OH)D deficiency in stone formers with high levels of 24-hour urinary calcium will not increase urinary calcium excretion by greater than 10%.
