NCT04378153
Despite the increasingly common use of cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapies in treating CF, it is still largely unknown whether or not other chronic therapies can be safely stopped. The SIMPLIFY study is being done to test whether or not it is safe to stop taking inhaled hypertonic saline or Pulmozyme® (dornase alfa) in those people that are also taking Trikafta™. Trikafta (elexacaftor/tezacaftor/ivacaftor) is a combination CFTR modulator therapy that was approved by the Food and Drug Administration for people with CF who have at least one F508del mutation. The three drugs that make up Trikafta work together to allow many more chloride ions to move into and out of the cells, improving the balance of salt and water in the lungs. These changes result in better clearance of mucus from the lungs and improvements in lung function. Inhaled hypertonic saline and Pulmozyme (dornase alfa) also improve clearance of mucus from the lungs to support lung function and have been available to people with CF for many years. Both therapies are considered to be relatively burdensome and it is not known whether either therapy can improve or maintain lung function above what is already gained through Trikafta use. The goal of the SIMPLIFY study is to get information about whether or not it is safe to stop either inhaled hypertonic saline or Pulmozyme (dornase alfa) by testing if there is a change in lung function in subjects with cystic fibrosis (CF) who are assigned to stop their chronic medication (either hypertonic saline or Pulmozyme) as compared to those who are assigned to keep taking their medication while continuing to take Trikafta.
NCT06119217
This is a Phase 2, multicenter, open-label, 3-arm, randomized, parallel group study to evaluate the efficacy and safety of TTX-030 with or without budigalimab in combination with chemotherapy (gemcitabine + nab-paclitaxel) in subjects with metastatic PDAC who did not have prior treatment for metastatic disease and are eligible to receive gemcitabine and nab-paclitaxel chemotherapy as SOC.
NCT03425643
This trial will evaluate the safety and efficacy of pembrolizumab (MK-3475) in combination with platinum doublet neoadjuvant chemotherapy (NAC) before surgery \[neoadjuvant phase\], followed by pembrolizumab alone after surgery \[adjuvant phase\] in participants with resectable stage II, IIIA, and resectable IIIB (T3-4N2) non-small cell lung cancer (NSCLC). The primary hypotheses of this study are that neoadjuvant pembrolizumab (vs. placebo) in combination with NAC, followed by surgery and adjuvant pembrolizumab (vs. placebo) will improve: 1) event free survival (EFS) by biopsy assessed by local pathologist or by investigator-assessed imaging using Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1); and 2) overall survival (OS).
NCT03643965
The overall aim of the study is to evaluate the efficacy, safety, and tolerability of Nefecon 16 mg per day in the treatment of patients with primary IgAN (Immunoglobulin A nephropathy) at risk of progressing to end-stage renal disease (ESRD), despite maximum tolerated treatment with renin-angiotensin system (RAS) blockade using angiotensin converting enzyme inhibitors (ACEIs) or angiotensin II type I receptor blockers (ARBs).
NCT01016353
This study is being done to gather data that will be used to compare two different TAC (Temporary Abdominal Closure) methods that your doctor may use. The two TAC methods being compared are the Barker's vacuum packing technique or BVPT and the Open Abdomen Negative Pressure Therapy System (ABThera) developed by the sponsor of this research (KCI, San Antonio, TX). The BVPT is made up of supplies that are stocked in most surgery rooms. The ABThera dressing is available commercially. Neither method will be supplied to the doctor (Principal Investigator), so that in no way would the subject's standard of care be different from what they would get if the study was not being done. This study is observational and only collects data about how the subject progresses after surgery TAC is used. When a study is observational it means that the subject's standard medical care will not be altered in any way, simply watched. The doctor will not change treatment of your open abdomen.
NCT05807763
Prospective randomized controlled trial to identify a sub-set of patients that do not benefit from the routine addition, and added morbidity, of a fundoplication during laparoscopic paraesophageal hernia repair.
NCT06008678
The goal of this clinical trial is to test the automatic positive airway pressure (APAP) function of the RXiBreeze PAP System in adult subjects with obstructive sleep apnea (OSA). The main questions the study aims to answer are: 1. Is apnea-hypopnea index (AHI) detection using the RXiBreeze PAP System equivalent to apnea-hypopnea index (AHI) detection using PSG? 2. What is the responder rate using the RXiBreeze PAP System? Participants will use the APAP function of the RXiBreeze PAP System while undergoing polysomnography (PSG) for two separate nights in a sleep center. During each visit, participants will also complete two patient reported outcome questionnaires: * Epworth Sleepiness Score (ESS); and * Functional Outcomes of Sleep Questionnaire (FOSQ) short form.
NCT06074601
The goal of this observational study is to develop and validate cell-free RNA-based biomarkers for predicting a variety of adverse pregnancy outcomes in a pregnant person population. The main question it aims to answer are: 1. Can cell-free RNA-based biomarkers predict which pregnant people are at greatest risk of developing adverse pregnancy outcomes (e.g., preterm birth, preeclampsia)? 2. What is the performance of such biomarkers when predicting an adverse pregnancy outcome (e.g., sensitivity, specificity, PPV, NPV, TPR)?
NCT04972838
The AIRB research team will compare the use and effectiveness of each intervention (Mind the Gap, Remaking Recess and Self Determination Learning Model of Instruction) with and without the addition of our implementation strategy, UNITED. In all groups, the research team will train community practitioners using remote delivery of professional development modules specific to the intervention, and active coaching for up to 12 sessions as dictated by the intervention procedures. The research team will pair UNITED with three interventions that cover the ages of early childhood, childhood, and adolescence. These include Mind the Gap (MTG), a family navigation intervention for children newly diagnosed under age 8, Remaking Recess (RR), a school-based social/peer engagement intervention for children ages 5-12, and Self-Determination Learning Model of Instruction (SDMLI), a self- advocacy intervention for adolescents (13-22 years; 22 is the upper age limit of high school for individuals with disabilities). For Remaking Recess, school personnel will be working with children with ASD using the Remaking Recess Intervention (play-based intervention done during recess). School personnel will be trained to implement the intervention. The total time commitment for the school personnel is about 30 hours. The total time commitment for the parents with ASD who will sign consents and fill out a demographic survey is about 15 minutes. The total time commitment for children with ASD or other neurodevelopmental disorders (NDD) is about 5 hours during their regularly scheduled recess period throughout the school year.
NCT02403323
This open-label extension and safety monitoring study is composed of two parts: Part 1 will evaluate the long-term safety and efficacy of continued etrolizumab treatment in participants with moderately to severely active Crohn's disease who were previously enrolled in the etrolizumab Phase III Study GA29144 (NCT02394028) and who meet eligibility criteria for enrollment into Part 1. In Part 2, participants who have stopped etrolizumab treatment (either by exiting Part 1 of this study or by entering directly from Study GA29144 \[NCT02394028\]) will be monitored for 92 weeks for progressive multifocal leukoencephalopathy (PML) and other safety events.

NCT03408314
PediQUEST Response proposes a new system of care that expects to improve quality of life in children, adolescents, and young adults with advanced cancer and their parents. The investigators want to learn whether patients that are cared for using PediQUEST Response do in fact feel better than those receiving usual care. National recommendations call for early palliative care (PC) integration for seriously ill children to ease suffering, however, very few randomized controlled trials (RCTs) have evaluated whether PC improves child and family outcomes. In prior work, the investigators developed the Pediatric Quality of Life and Evaluation of Symptoms Technology (PediQUEST/PQ), a software that collects electronic Patient-Reported Outcomes (e-PROMS) and generates feedback reports. Now, the PI and research team developed PediQUEST Response (Response to Pediatric Oncology Symptom Experience). PediQUEST Response includes an enhanced PediQUEST system (web-based and with an App that allows to answer surveys and see reports), that is coupled with early integration of a palliative care consulting team (Response team). This dual strategy will help to standardize the family report of distress, which will be done through the PediQUEST system. It will also help standardize the providers' response to such distress, as providers will be specifically trained. Pilot work for PediQUEST Response found it feasible, well received by families and oncologists, and potentially effective. Thus, the overall goal of this study is to conduct a RCT of PQ Response versus usual care at four large pediatric oncology centers among 136 children ≥2 years old with advanced cancer. Hypotheses include a) children receiving the intervention will have better (higher) quality of life scores b) parents of children in the intervention group will report better state-anxiety, depression and symptom-related stress scores, and c) intervention group families will demonstrate higher levels of activation.
NCT03671018
This study will evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and efficacy of intravenous (IV) or subcutaneous (SC) mosunetuzumab in combination with polatuzumab vedotin in participants with diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), and mantle cell lymphoma (MCL). It will consist of a dose finding portion followed by an expansion phase for second line or later (2L+) participants with relapsed or refractory (R/R) DLBCL and 2L+ R/R FL. In addition, subcutaneous mosunetuzumab in combination with polatuzumab vedotin will be evaluated in participants with at least 2 prior lines of systemic therapy (3L+) for the treatment of R/R mantle cell lymphoma (MCL) and in participants with 2L+ R/R DLBCL.

The GARDENIA registry will collect real-world clinical data on the anticoagulant strategies in patients with AF at elevated risk of stroke but also elevated risk of bleeding.
NCT03828318
After undergoing restorative proctectomy for rectal cancer, many patients are left with significant bowel dysfunction, known as Low Anterior Resection Syndrome (LARS). Increased LARS severity correlates with worse perceived global health status and quality of life (QoL). Among patients undergoing rectal resection with a permanent ostomy, there is evidence that supportive and educational interventions improve QoL, ostomy proficiency, self-efficacy and knowledge. However, evidence regarding the impact of such interventions in patients who undergo restorative proctectomy is lacking, despite the latter operation being far more frequently performed. The overall goal of this study is to evaluate the extent to which a LARS Patient-Centered Program impacts on patient-reported outcome measures (PROMs) after restorative proctectomy for rectal cancer. This is a randomized-controlled muticenter trial that will include patients who have undergone restorative proctectomy for neoplastic disease (benign or malignant) located in the rectum (0-15cm from the anal verge) with a diverting ostomy and who are scheduled for ostomy closure.
NCT04469426
After surgery for rectal cancer, many people undergo changes in bowel habits, which may include the need to empty their bowels more often, accidental leakage of stool or gas, the sudden urge to go to the bathroom, and more. The term "Low Anterior Resection Syndrome" or LARS is used to describe these symptoms. LARS has a negative impact on one's quality of life, and can lead to frustration, as there is no single intervention that has proven to be effective for LARS, and each patient has to undergo trial and error to find one's solution. As people struggle with LARS, they describe feeling hopeless and isolated. Peer support is a supportive relationship between individuals who share common experiences or face similar challenges. The goal of our study is to evaluate whether use of an online peer support application with trained mentors who themselves have lived or are living with LARS will empower patients to better manage their LARS symptoms and improve their quality of life.
NCT04233034
Randomized trial of youth aged 7-\<18 years with newly diagnosed stage 3 type 1 diabetes (T1D) to assess the effect of both (1) near-normalization of glucose concentrations achieved through use of a hybrid closed loop (HCL) system and (2) verapamil on preservation of β-cell function 12 months after diagnosis. Participants with body weight ≥30 kg (Cohort A) will be randomly assigned in a factorial design to (1) HCL plus intensive diabetes management or usual care with no HCL and (2) verapamil or placebo. Participants with body weight \<30 kg (Cohort B) will be randomly assigned 2:1 in a parallel group design to HCL plus intensive diabetes management or to usual care with no HCL.
