NCT00378209
The purpose of this study is to evaluate the effectiveness and side effects of the bortezomib, lenalidomide and dexamethasone combination in relapsed or relapsed and refractory multiple myeloma. Each of these drugs are approved by the U.S Food and Drug Administration, but have not been approved in the combination for treating patients in this setting.
NCT02958358
The investigators are doing this research study to find out how blood flow changes in the lungs of people with pulmonary hypertension before and after treatment with ambrisentan (sold under the brand name Letairis). The investigators hope that knowing about these differences will help us to better understand pulmonary hypertension and find new ways to diagnose it earlier.
NCT01612429
This is a pilot study to evaluate the effects of amino acid supplementation on the structure of certain proteins in the blood of dialysis patients. Patients with end stage renal disease (ESRD) usually have high levels of urea that may interact with blood proteins and change their structure by a process known as carbamylation. The investigators are interested in determining whether carbamylation is linked to adverse outcomes in dialysis patients and have hypothesized that supplementation with a balanced formulation of amino acids can reduce the amount of carbamylation that occurs. In this study, dialysis patients (n= up to 30) will receive intravenous supplementation with an FDA-approved amino acid solution (NephrAmine®, 5.4% amino acids) during regular dialysis sessions (3 times weekly for 6 weeks). During the 6 weeks of therapy and for 2 weeks of follow-up, blood will be drawn from patients' existing hemodialysis access ports (\~60 ml total per month) to measure levels of carbamylated albumin, amino acids, and standard laboratory values. Patients will be closely monitored for safety and tolerability of the amino acid therapy. For each treated subject, we will follow an additional individual that is not receiving treatment to serve as a control (no intervention).
