NCT01626573
This is a study evaluating a 28-day course followed by a 56-day course of itacitinib in patients with active rheumatoid arthritis (RA). The study will evaluate safety and efficacy parameters of itacitinib.
NCT00570700
The purpose of this research study is to find out if a new anti-cancer drug, dasatinib (Sprycel®), previously approved for treatment of some forms of leukemia, will be safe and helpful in treating patients with hormone-refractory prostate cancer. This is a research study because the study drug, dasatinib (Sprycel®), has not been evaluated for safety or effectiveness in patients with hormone-refractory prostate cancer. The drug is approved by the Food and Drug Administration for treatment of some forms of leukemia; thus, dasatinib (Sprycel®) is not an investigational drug. It has been given safely to hundreds of patients already. However its safety and usefulness in this study population (prostate cancer) is unknown. Subjects who agree to participate will take 150mg (3 pills) of dasatinib (Sprycel®) daily by mouth for as long as the drug benefits them. During this time, the subject will periodically return to the office for blood/urine tests, X-rays, imaging scans, and/or to complete questionnaires.
NCT02614612
To determine if Itacitinib in combination with corticosteroids is safe and tolerable in patients with Grade IIB-IVD acute graft-versus-host disease (GVHD).
NCT01983293
The purpose of this study is to analyze the effect of left ventricular lead pacing location in the non-left bundle branch block (non-LBBB) heart failure patient population. The left ventricular lead pacing location will be guided by either the pacing site with the largest amount of dyssynchrony as measured by the LV electrical delay (QLV) or the physician's standard of care implant approach.
NCT01817712
The primary objective of CSP#589 VIP-STAR is to evaluate the effectiveness of Individual Placement \& Support (IPS) in unemployed Veterans with PTSD. The primary hypothesis is that, compared to those treated with transitional work program (TWP), unemployed Veterans with PTSD treated with IPS will be significantly more likely to become a steady worker. A steady worker is defined as holding a competitive job for greater than or equal to 50% of the 18-month study follow-up period (i.e., greater than or equal to 39 of the 78 weeks). All participants will be followed for 18 months post-randomization. 12/14/12: Analytic plan augmented to allow for a sensitivity analysis of the primary outcome that would exclude the first 12 weeks post-randomization, and evaluate between group proportion of steady worker status, as defined by working in a competitive job for greater than or equal to 50% of the weeks during week 13-78. 7/1/13: Analysis plan has been augmented to include a logistic regression analysis of the primary outcome, adjusted for participating medical center. 10/4/13: Addition of the IPS-25 Fidelity Scale. The addition of the IPS-25 scale should increase the validity of study results. 1/15/15: Addition of an Interactive Voice Recognition/Web-based (IVR/Web) System; as an option for weekly data capture of the primary outcome data (employment history). 8/17/15: Approval of Supplemental Data Collection at Participant Study Exit; use of the data collected will supplement the study analysis plan and, provide further insight into the impact of vocational rehab. A Participant Satisfaction Survey will allow study participants to indicate their level of satisfaction with the study, vocational rehabilitation intervention and, suggestions for future research.
NCT02132767
The purpose of this study is to compare the therapeutic strategies of rate control versus rhythm control in cardiac surgery patients who develop in-hospital postoperative atrial fibrillation or atrial flutter (AF). In patients who develop AF during hospitalization after cardiac surgery, the hypothesis is that a strategy of rhythm control will reduce days in hospital within 60 days of the occurrence of AF compared to a strategy of rate control.
NCT00807040
People with coronary artery disease (CAD) or people who have had a heart attack may develop a leak in the mitral valve of their heart and may therefore need to undergo surgery to fix the valve. The best way to fix the mitral valve remains undetermined. This study will evaluate whether it is better for people with severe mitral valve leakage to undergo a mitral valve replacement procedure or a mitral valve repair procedure.
NCT01875874
This phase 2 study is developed to evaluate the effect of ELAD on overall survival (OS) in subjects with acute liver failure (ALF) compared to matched historical controls.
NCT03143517
The primary objective is to obtain stool samples from subjects diagnosed with , and displaying signs and/or symptoms of IBD and/or IBS will be evaluated in this study. Eligible subjects require a diagnostic colonoscopy with possible biopsy and clinical evaluation.
NCT00257231
The purpose of this study is to help improve our understanding of the biology involved in the body's response to serious trauma or burn injury. The host response to trauma and burns is a collection of physiological and pathophysiological processes that depend critically upon the regulation of the human innate immune system, with particular emphasis on the inflammatory component of that system. No single research center or small group of centers has the capacity to delineate the integrated response of this complex biological system, which involves multiple molecular and genetic interactions that vary in time. Our proposal promotes the identification of important dynamic relationships that regulate the integration of this complex biological system, with the expectation that this understanding will ultimately impact the diagnosis, prognosis, and treatment of the hospitalized, severely injured patient.
NCT00135694
In order to prevent organ rejection, patients receiving liver transplants currently require life-long treatment with immune system-suppressing medications to prevent the rejection of the transplanted liver. However, these medications can cause long-term side effects, such as infection, kidney problems, diabetes, and cancer. In patients infected with hepatitis C virus (HCV), these medications may increase the risk of HCV infection in the transplanted liver. The purpose of this study is to determine whether a slow withdrawal of immune system-suppressing medications is safe in two groups of subjects: those who receive a liver transplant due to HCV, and those who receive a liver transplant due to non-immune, non-viral causes of liver failure. The study will also look at whether slow withdrawal will help reduce the long-term side effects of immune system-suppressing medications and decrease the chance for HCV infection of the new liver in transplant patients with HCV.
NCT01319812
The objective of this study is to separately demonstrate the safety and efficacy of BIOTRONIK's Astron and Pulsar stents. The Pulsar stent will be used for the treatment of femoro-popliteal lesions, located in the native superficial femoral artery (SFA) or proximal popliteal artery (PPA), while the Astron stent will be used for the treatment of the common or external iliac artery lesions.
NCT03202992
This study evaluates the use of ABI-1968, a topical cream, in the treatment of anal precancerous lesions in adults with and without human immunodeficiency virus (HIV) infection.
NCT00068237
RATIONALE: Moving a salivary gland out of the area that will undergo radiation therapy may protect the gland from side effects of radiation therapy and may prevent xerostomia (dry mouth). PURPOSE: Phase II trial to study the effectiveness of salivary gland surgery in preventing xerostomia in patients who are undergoing radiation therapy for head and neck cancer.
