NCT05753748
The purpose of this study is to learn the best approach to treating patients with known or suspected Barrett's esophagus by comparing endoscopic surveillance to endoscopic eradication therapy. To diagnose and manage Barrett's esophagus and low-grade dysplasia, doctors commonly use procedures called endoscopic surveillance and endoscopic eradication therapy. Endoscopic surveillance is a type of procedure where a physician will run a tube with a light and a camera on the end of it down the patients throat and remove a small piece of tissue. The piece of tissue, called a biopsy, is about the size of the tip of a ball-point pen and is checked for abnormal cells and cancer cells. Endoscopic eradication therapy is a kind of surgery which is performed to destroy the precancerous cells at the bottom of the esophagus, so that healthy cells can grow in their place. It involves procedures to either remove precancerous tissue or burn it. These procedures can have side effects, so it is not certain whether risking those side effects is worth the benefit people get from the treatments. While both of these procedures are widely accepted approaches to managing the condition, there is not enough research to show if one is better than the other. Barrett's esophagus and low-grade dysplasia does not always worsen to high-grade dysplasia and/or cancer. In fact, it usually does not. So, if a patient's dysplasia is not worsening, doctors would rather not put patients at risk unnecessarily. On the other hand, endoscopic eradication therapy could possibly prevent the worsening of low-grade dysplasia into high-grade dysplasia or cancer (esophageal adenocarcinoma) in some patients. Researchers believe that the results of this study will help doctors choose the safest and most effective procedure for their patients with Barrett's esophagus and low-grade dysplasia. This is a multicenter study involving several academic, community and private hospitals around the United States. Up to 530 participants will be randomized. This study will also include a prospective observational cohort study of up to 150 Barrett's esophagus and low grade dysplasia patients who decline randomization in the randomized control trial but undergo endoscopic surveillance (Cohort 1) or endoscopic eradication therapy (Cohort 2), and are willing to provide longitudinal observational data.

This study is a prospective, non-randomized, multicenter, single-arm, clinical study to evaluate the performance, safety and efficacy of the GORE® VIABAHN® FORTEGRA Venous Stent (formerly known as GORE® VIAFORT Vascular Stent) for treatment of symptomatic iliofemoral venous obstruction.
NCT05131984
The primary aim of this project is to determine whether there are differences in access to, efficacy and tolerability of Ocrelizumab in men and women of different racial and ethnic origins and socio-economic backgrounds with RRMS and PPMS in two large academic MS Centers with a high volume of patients on Ocrelizumab. The study is a retrospective analysis of multiple sclerosis patients cared for at Brigham and Women's Hospital and Boston Medical Center who were treated with Ocrelizumab during the 4 year study period.
NCT05016908
Current methods of measuring the response to new treatments for muscular dystrophies involve the examination of small pieces of muscle tissue called biopsies. The investigators are interested in finding less invasive methods that reduce the need for muscle biopsies. The purpose of this research is to learn about the possibility of detecting and measuring the activity and severity of muscular dystrophies by examining a urine sample and a blood sample.

NCT03368157
The purpose of the study is to develop a detailed pregnancy registry of patients with Multiple Sclerosis in the New England states. Women with a diagnosis of MS that are either pregnant or actively planning to become pregnant are eligible to participate. The study will solely take place through phone interviews. One of the study coordinator at the Partners MS Center will contact the participant for an intake phone interview where general information about the individual, their pregnancy and their MS will be collected. Thereafter the coordinator will contact the participant every 3 months for 20 minutes follow up interviews. After birth, the coordinator will collect information on the growth and development of the participant's baby. Pediatric interviews will be conducted at 2, 4, 6, 9, 12, 18, 24, 36 months. Information from the participant's neurologist and obstetrician, as well as information from the baby's pediatrician, will be made available to the study staff at regular intervals throughout the duration of the study. Through this study, the investigators hope to learn more about the effects of MS on pregnancy and pediatric development, and about the effects of pregnancy on the course of MS.
NCT06331403
The primary goal of this protocol is to conduct an open pilot to collect initial quantitative and qualitative feedback on the intervention that the investigators are developing. To do so, the investigators will deliver a newly-developed intervention to up to 2 consecutive groups of female colorectal and anal cancer survivors (n = up to 10 per group, total N = up to 20). Participants will provide feedback regarding intervention acceptability, feasibility, and perceived benefit. To inform plans for ongoing program refinement, the investigators will elicit specific feedback about study assessment tools, recruitment procedures, and group factors. Given the early-stage, open pilot nature of this protocol, the investigators will not set strict criteria to establish feasibility and acceptability but will rather interpret each of these outcomes holistically. Qualitative feedback collected in post-intervention exit interviews will also support understanding of feasibility and acceptability. As a secondary aim, the investigators will explore the preliminary effects of the intervention on psychosocial measures of satisfaction with sexuality and impact of functional limitations, coping abilities, acceptance of body image changes, loneliness, and anticipated stigma. As noted above, the investigators will not set specific criteria to establish preliminary efficacy, nor will they consider statistical significance as an indicator of the study's efficacy for these outcomes. Instead, the investigators will consider pre-post intervention effect sizes to consider the need for refinement of study procedures/measurement in a future larger trial. In future, larger-scale, work, the investigators intend to conduct a larger randomized pilot trial to assess intervention acceptability, feasibility, as well as preliminary efficacy on essential outcomes related to sexual well-being.
NCT04107649
Total knee replacement (TKR) is a common and costly procedure widely used to relieve pain and improve function in patients with symptomatic advanced knee osteoarthritis (OA). As of 2013, the annual incidence of TKR was over 680,000 surgeries and annual costs exceeded $11 billion. Growing evidence suggests that while pain and functional status improve following TKR, physical activity (PA) typically does not surpass pre-TKR levels. Engagement in PA can meaningfully improve quality of life (QoL), pain, and function. Given the large investment in TKR, the effectiveness and cost-effectiveness of TKR could be substantially increased if TKR recipients became more physically active. The Knee Arthroplasty Activity Trial (KArAT) is a randomized controlled trial and participants will be randomly assigned to one of three arms. Participants across all arms will receive usual post-operative care for TKR surgery. Participants in the first arm will complete basic study activities, such as responding to surveys and attending two in-person clinic visits. Participants in the second arm will do the same and also receive a wrist-based physical activity tracker intervention. Participants in the third arm will receive a telephonic active coaching (motivational interviewing) and financial incentives (for reaching physical activity goals) (TAC(MI)+FI) based intervention, as well as a wrist-based physical activity tracker intervention. The second and third arms will be eligible to receive lottery-based financial rewards for wearing a wrist-worn activity tracker for twenty-four months during the study.

NCT06207370
This study is a double-blind, randomized, multisite, placebo-controlled trial comparing the safety and efficacy of TQ versus placebo in patients hospitalized for babesiosis with low risk for relapsing disease who will also be administered a standard-of-care antimicrobial regimen (A/A) that is recommended in the 2020 IDSA guideline on the diagnosis and management of babesiosis.
NCT05738330
The SMaRRT-HD trial is a cluster randomized trial of symptom monitoring with supported clinician follow-up using the SMaRRT-HD electronic patient reported outcome measure (ePROM) system versus Usual Care. Approximately 2400 patients at up to 36 geographically and racially diverse US hemodialysis clinics will be enrolled. The primary trial hypothesis is that regular symptom patient reported outcome measure (PROM) administration with supported clinician follow-up in dialysis care will reduce suffering and improve outcomes by prompting treatment of unrecognized symptoms, and enhancing patient-care team communication. Clinics randomized to the SMaRRT-HD group will adopt the use of SMaRRT-HD for 12 months. SMaRRT-HD is a symptom monitoring system that includes 1) tablet-based symptom reporting using a PROM and 2) supported clinician follow-up consisting of symptom alerts, guidances for symptom management, and symptom tracking reports that are shared with patients. Dialysis clinics randomized to Usual Care will not adopt SMaRRT-HD or any other trial-driven procedures. Usual Care clinics will monitor symptoms through clinical care interactions with participants and by administering a Health Related Quality of Life survey that includes questions about symptoms.

NCT01286272
This randomized phase II trial studies how well ofatumumab and bendamustine hydrochloride with or without bortezomib works in treating patients with untreated follicular non-Hodgkin lymphoma. Monoclonal antibodies, such as ofatumumab, may block cancer growth in different ways by targeting certain cells. Drugs used in chemotherapy, such as bendamustine hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Bortezomib may also stop the growth of cancer cells by blocking blood flow to the tumor. It is not yet known whether ofatumumab and bendamustine hydrochloride are more effective with bortezomib in treating patients with follicular non-Hodgkin lymphoma.
