NCT03734016
This study is designed to compare the overall response rate of zanubrutinib versus ibrutinib in participants with relapsed/refractory chronic lymphocytic leukemia or small lymphocytic lymphoma.
NCT04804033
The purpose of this is study is to compare the efficacy of BHV-3500 (zavegepant) to placebo as a preventive treatment for migraine, as measured by the reduction in the number of migraine days per month.
NCT03203603
The overall aims of this protocol are to determine whether prenatal supplementation with vitamin C to pregnant smokers can improve pulmonary function and decrease wheeze at 5 years of age in their offspring. This is a continuation of the VCSIP trial, to follow the offspring through 5 years of age. The hypothesis for this protocol is an extension of the VCSIP trial that supplemental vitamin C in pregnant smokers can significantly improve their children's PFTs and decrease the incidence of wheeze.
NCT03241459
To demonstrate the safety and efficacy of the SurVeil Drug-Coated Balloon (DCB) for treatment of subjects with symptomatic peripheral artery disease (PAD) due to stenosis of the femoral and/or popliteal arteries.
NCT02276872
This was a multi-center, open-label, safety, tolerability and pharmacokinetic study of oral treprostinil in pediatric subjects with stable PAH aged 7 to 17 years who were (1) transitioning from parenteral Remodulin therapy; (2) transitioning from inhaled prostacyclin therapy; or (3) not currently receiving prostacyclin therapy.
NCT03707158
The Kids FACE FEARS (Kids Formats of Anxiety Care Effectiveness study For Extending the Acceptability and Reach of Services) is a large-scale, streamlined, pragmatic Randomized Controlled Trial (RCT) evaluating Therapist-Led CBT (telehealth, office-based, or hybrid) vs. Guided Online Cognitive-Behavioral Therapy (CBT) for the treatment of elevated child and adolescent anxiety. Families will be recruited from pediatric health centers serving primarily racial/ethnic minority youth in urban, suburban, and semi-rural regions. Services will be offered in English and Spanish. Patient-centered outcomes will be evaluated across a one-year follow-up period. To compare the effectiveness of the two treatment comparators, investigators will analyze the reports of caregivers, youth, and therapists, as well as independent evaluators who are not informed of each child's treatment assignment. Primary outcomes will focus on family-rated anxiety severity and impairment, treatment responder and remission status rated by independent evaluators, family-perceived effectiveness, and treatment satisfaction. Secondary analyses will examine additional outcomes, predictors of varied outcomes across different subgroups of youth, and facilitators and barriers to treatment implementation. Caregivers, patients, providers, and other key stakeholders will be actively engaged throughout all aspects of the research.
NCT05855083
The purpose of this study is to evaluate the safety and efficacy of narsoplimab in pediatric patients with thrombotic microangiopathies (TMA) following hematopoietic stem cell transplant (HSCT).
NCT02994927
The primary objective is to evaluate the efficacy of CCX168 (avacopan) to induce and sustain remission in patients with active anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), when used in combination with cyclophosphamide followed by azathioprine, or in combination with rituximab.
NCT05118893
This is an extended follow up study of the original RAFT-AF Study. The RAFT-AF study was a multi-centre randomized controlled trial with a prospective randomized open blinded endpoint trial (PROBE) design. Patients were randomized to either catheter ablation-based rhythm control of AF as compared to rate control of AF
NCT05248997
The purpose of this study is to compare the efficacy and safety of rimegepant versus placebo in the acute treatment of chronic rhinosinusitis (CRS) with and without nasal polyps.
NCT05825898
Tricuspid regurgitation (TR) is a public health problem: moderate / severe TR are common, especially in ageing populations, and affect 4% of the population \>75 years old, totaling approximately 1.6 million in the US and 3 million in Europe. TR is associated with an increased risk of mortality and morbidity. Contrasting with TR prevalence and the magnitude of the problem, the vast majority of patients are medically treated with diuretics to relieve their symptoms and a curative surgical treatment for isolated severe TR is seldom performed. Reluctance to perform an ITVS can be explained in the one hand by the limited evidence that TR correction improves outcomes and on the other hand, ITVS is associated to high observed in-hospital mortality rates (≈ 10% remarkably consistent in most series across the literature). Severity of the clinical presentation is the main predictor of outcome after surgery. The TRI-SCORE, is a dedicated, simple and accurate risk score model to predict in-hospital mortality after ITVS that could guide the clinical decision-making process at the individual level. Excellent outcomes can be achieved when patients present with low TRI-SCORE. These results suggest adopting a more pro-active approach for TV interventions, and to intervene earlier in the course of the disease in patients with severe isolated TR, irrespective of TR mechanism / etiology, before the occurrence of advanced / irreversible consequences such as severe RV dilatation / dysfunction, renal and liver failure, and intractable heart failure. Recently transcatheter tricuspid valve interventions (TTVI) have emerged recently as a less invasive option to surgery to cure patients with TR. What is the best treatment between medical, surgical or transcatheter therapy to consider and the best timing for each patient are not clearly defined. The aim of the study is to compare outcome of patients with significant functional TR according to medical, transcatheter or surgical treatment after matching per TRISCORE.
NCT04767919
The decision to use standard percutaneous nephrolithotomy (PCNL) versus mini-percutaneous nephrolithotomy (MIP) has been a subject of much debate in the urological community. The investigators propose a randomized controlled trial to compare the operative outcomes and complications of mini-percutaneous nephrolithotomy (mini-PCNL) versus standard PCNL for renal stones. The results of this study will help guide the decision making regarding these two procedures in the US population and provide further insight into the utility and safety of these procedures. A cost analysis will be performed, and it is hypothesized that the reusable components of the Storz MIP set will result in lower costs of the mini-PCNL procedure compared to standard PCNL.
NCT04199689
The purpose of this study is to evaluate the efficacy, immunogenicity and safety of the 9vHPV vaccine in men 20 to 45 years of age. The primary hypothesis tested after the primary database lock is that administration of a 3-dose regimen of 9vHPV vaccine will reduce the incidence of human papillomavirus (HPV) 16/18/31/33/45/52/58-related oral persistent infection (6 months or longer) compared with placebo. There will also be an Extension Study to offer an opportunity to complete the 3 dose regimen of 9vHPV vaccine for participants who received placebo in the Base Study, or received less than 3 doses of 9vHPV vaccine in the Base Study.
NCT03631784
This is a trial in adult participants with unresectable, locally advanced, Stage III non-small cell lung cancer (NSCLC) treated with pembrolizumab in combination with platinum doublet chemotherapy and standard thoracic radiotherapy followed by pembrolizumab monotherapy. The primary hypothesis of the trial is that within each platinum doublet chemotherapy cohort, the percentage of participants who develop Grade 3 or higher pneumonitis is ≤10% and estimation of objective response rate (ORR) by blinded independent central review (BICR).
NCT04035226
The purpose of this study is to assess the safety and clinical response including overall response rate (ORR) of real-life standard-of-care (SOC) treatments under routine clinical practice, over a 24-month period, in patients with relapsed/refractory multiple myeloma (RRMM).
NCT05552508
