Filter by:The current phase 0 trial is preceding the phase 1/2 trial of a newly developed drug, NAITgam, for the prevention of fetal and neonatal alloimmune thrombocytopenia (FNAIT) - a rare, but potentially very severe bleeding condition in the fetus or newborn. FNAIT may occur in women whose blood platelets do not express HPA-1a. If the fetus has inherited HPA-1a from the father, the mother's immune system may be stimulated to produce HPA-1a antibodies if HPA-1a positive fetal blood platelets enter the maternal circulation during delivery. In a subsequent pregnancy, such antibodies will cross the placenta and may reduce the number of HPA-1a positive blood platelets in the fetus, which in turn may result in severe bleeding in the fetus or newborn. The phase 1/2 study of NAITgam will examine NAITgam's ability to eliminate HPA-1a positive blood platelets that has been transfused to healthy male subjects, whose blood platelet do not express HPA-1a. The ability to quickly eliminate transfused HPA-1a positive platelets is considered as a surrogate endpoint for NAITgam's ability to prevent formation of antibodies against HPA-1a after delivery of an HPA-1a positive child. The current phase 0 trial will examine the survival of blood platelets transfused to healthy male individuals without subsequent administration of NAITgam. The natural survival of transfused platelet, as determined in the phase 0 trial, will be compared with the survival of transfused HPA-1a positive platelets after administration of NAITgam in the phase 1/2 trial. The aim of the phase 0 trial is first, to determine the dose of blood platelet that should be transfused to the healthy subjects in the phase 1/2 trial; and secondly, to determine the optimal time point, after transfusion of platelets, for administration of NAITgam in the phase 1/2 trial. Eight to 24 healthy male subjects will be included in the phase 0 trial. After transfusion of platelets, blood samples will be collected at regular intervals to determine the proportion of transfused blood platelets. Differences between tissue type antigens between donor and recipient will be used to determine the proportion of transfused platelets. Survival of transfused platelets will be performed by flow cytometry - a method that can be used to quantify very small proportions of cells in the blood. Fluorochrome-conjugated monoclonal antibodies against HLA-A2 and HLA-A9 will be used for flow cytometric identification the transfused platelets.
Tuberculosis is the current leading cause of death due to an identifiable infectious agent worldwide. The current standard regimen for tuberculosis requires a patient to take drug combination (isoniazid, rifampicin, ethambutol, and pyrazinamide) for six to eight month periods. The purpose of this study is to compare tuberculosis treatment therapy between the current standard regimen and PRS derived combinatorial regimen. PRS derived regimen may potentially allow for a shorter course of treatment, which may reduce problems associated with adherence, toxicity, and development of drug resistance.
A pragmatic, quasi-experimental (non-randomized) design was used to evaluate clinical and cost outcomes among patients with type 1 or 2 diabetes (T1D or T2D) at two primary care clinics (n=1 intervention, n=1 usual care) between March 2012 and September 2014. At the intervention clinic, the 12-month Cardio-metabolic Care-Team Intervention (CMC-TI) was delivered to all qualifying patients; surveys were administered to evaluate relevant patient-reported outcomes over 12 months, and a process evaluation gauged CMC-TI feasibility and satisfaction.
Recurrent vulvovaginal candidiasis (RVVC), also known as recurrent yeast infections, is defined as at least 3 episodes of acute VVC in the past 12 months. Several properties of oteseconazole (VT-1161) suggest that it might be a safer and more effective treatment for RVVC than other oral antifungal medicines. This study will evaluate the effectiveness and safety of oteseconazole (VT-1161) for the treatment of RVVC and consists of 2 parts. The first part of the study is a 2-week period for the treatment of the patient's current VVC episode with 3 150mg doses of fluconazole. The 2nd part consists of 12 weeks, when the patient will take either oteseconazole (VT-1161) 150 mg or a placebo (according to a random assignment), and then a 36-week follow-up period. In addition, at participating sites, an amendment to the study allows US patients who complete the initial 48 weeks without experiencing a confirmed RVVC episode to continue in a 48-week observational extension period designed to evaluate the continued effectiveness of oteseconazole (VT-1161). This study is identical to VMT-VT-1161-CL-011.
The overall purpose of this project is to investigate the neuro adaptations of pain and biomechanical differences between placebo and a custom-made foot orthoses for patients with RA.
Aggressive hydration of lactated Ringer's solution has shown considerable beneficial effect in preventing post-ERCP(endoscopic retrograde cholangiopancreatography) pancreatitis. But the occurence rate of post-ERCP pancreatitis are near 10% and there are severe complications of aggressive hydration due to hypervolemia such pulmonary and peripheral edema, prolonged hospital stay and increased medical expense. Also there are no definite guidelines that suggest the duration and amount of hydration. This study evaluates the efficacy and safety of tailored hydration depending on each patient's condition that indicates the likelihood of developing post-ERCP pancreatitis.
The study is a two-year prospective observational study of patients treated with teriflunomide. The investigators will recruit up to 75 patients at baseline, based on the estimate that approximately 20% of these patients (~ 15 patients) will have evidence of disease activity at the end of the first year of treatment with teriflunomide, as determined by clinical evaluation (relapses) and MRI activity (new T2 hyperintense lesions). The investigators will assess the expression of a putative biomarker signature consisting of toll like receptor 2(TLR2), TLR4 and chemokine receptor 1 (CCR1) on CD4 T-subsets at baseline and at intervals on treatment with teriflunomide to determine whether expression of this biomarker signature on one or more CD4 T-subsets correlates with disease activity.
The aim of this study will be to test the accuracy of Sonography in determining the endotracheal tube size in pediatric patients whether cuffed or un-cuffed.
The principal aim of the study is to determine whether the hemodynamic parameters measured with the two methods -impedance cardiography and applanation tonometry- can be predictive of the antihypertensive effect of two different classes of drugs, ATII antagonists and diuretics. The drugs that will be used in the study are olmesartan and chlorthalidone and the duration of the study is 12 months. The other basic aim of the study is to determine whether there is a difference (>6mmHg) between the two drugs regarding the reduction of the mean 24hour blood pressure and the effect of them on the hemodynamic parameters. The hemodynamic parameters that will be measured by applanation tonometry are augmentation index, central blood pressure and pulse wave velocity. The hemodynamic parameters that will be measured by impedance cardiography are cardiac index, thoracic fluid content index, systemic vascular resistance index and others.
The purpose of this study is to investigate the coagulation balance in a cohort of congenital disorder of glycosylation (CDG) patients using conventional tests combined with an integrated approach of their coagulation disorders in using TGA in the absence or presence of sTM. Thus, investigators aimed to define if the hemostatic balance in CDG patients, is preserved despite of combined deficiencies in both procoagulant and anticoagulant factors.
