NCT01423058
The myeloproliferative neoplasms (MPN), most notably polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF) are a diverse but inter-related suite of clonal disorders of pluripotent hematopoietic stem cells (Tefferi et al., 2008). The MPN share a range of biological, pathological, and clinical features including the relative overproduction of one or more cells of myeloid origin, growth factor independent colony formation in vitro, marrow hypercellularity, extramedullary hematopoiesis, spleno- and hepatomegaly, and thrombotic and/or hemorrhagic diatheses (Tefferi et al., 2005). This is a multi-centre, open-label, non-randomized, dose-escalation study, to be conducted in two phases: a dose-escalation phase (Part 1), to determine the safety and tolerability of momelotinib (CYT387), and to identify a therapeutic dose for the expanded cohort; and a dose-confirmation phase (Part 2), which will be a cohort expansion at or below the MTD of momelotinib. In the Part I dose-escalation phase of the study, subjects will be assigned to dose levels in successive cohorts starting with a dose in the first cohort of 200 mg BID (twice daily with doses taken approximately 12 hours apart). Doses will be escalated by 50 mg BID per cohort until dose-limiting toxicities are observed. The dose level at which ≥2 of 6 subjects develop a first cycle dose-limiting toxicity (DLT) is defined as the DLT level. The maximum tolerated dose (MTD) is defined as the dose level below the DLT level. New dose levels may begin accrual only if all subjects at the current dose level have been observed for a minimum of 28 days from the first day of treatment. The dose level chosen for study in the dose confirmation phase of the study will be the MTD or a lower dose shown to have significant clinical activity (efficacy) as determined by the safety review committee. Subjects will be evaluated weekly for the first cycle, every 2 weeks during cycle 2, then monthly for 4 cycles for a total of 6 cycles. In the dose-confirmation phase of the study, approximately fifty (50) subjects will be treated at the MTD or at a lower dose shown to have significant clinical activity (efficacy) as chosen by the Safety Review Committee. In the dose confirmation phase of the study subjects will be evaluated every 2 weeks during the first treatment cycle, and then monthly for 5 cycles for a total of 6 cycles.
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.
NCT00005772
This large multicenter trial tested whether cerebral cooling initiated within 6 hours of birth and continued for 72 hours would reduce the risk of death and moderate to severe neurodevelopmental injury at 18-22 months corrected age. Infants at least 36 weeks gestation with an abnormal blood gas within 1 hour of birth, or a history of an acute perinatal event and a 10-min Apgar score \<5, or continued need for ventilation were screened. Following a neurological exam, those with moderate to severe encephalopathy were randomized to a 72-hour period of total body cooling (cooling blanket, followed by slow re-warming). The study was conducted in two phases: Phase I (20 infants) were examined for the safety of an esophageal temperature of 34-35 C; Phase II (main trial, 200 infants) were evaluated for the safety and efficacy of an esophageal temperature of 33-34 C. Cardio-respiratory, electroencephalograms (EEGs), renal, metabolic, and hematologic status, and esophageal and abdominal skin temperature were monitored during the 72 hours of intervention. Surviving children were given neurodevelopmental examinations at 18-22 months corrected age and again at school age (6-7 years of age).
NCT00009620
This large randomized trial tested whether phenobarbital given to a pregnant woman about to deliver a premature infant would prevent brain injuries in their newborns. Women with 24 to 32 week fetuses who were in preterm labor and were expected to deliver within 24 hrs were randomized to phenobarbital or usual care. They were treated until they deliver or the fetus reaches 33 wks gestation. Babies were followed until discharge and evaluated at 18-22 mos corrected age for neurodevelopmental outcome.
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
