NCT06291220
Chronic lymphocytic leukemia (CLL) is the most common leukemia in Western countries. The purpose of this study is to assess how well ABBV-453 works adult participants with relapsed/refractory (R/R) untreated CLL/small lymphocytic lymphoma (SLL). Adverse events, pharmacokinetics, and change in disease activity will be assessed. ABBV-453 is an investigational drug for the treatment of CLL and SLL. Participants will be enrolled with a specific target dose and receive obinutuzumab during the debulking period followed escalating doses of ABBV-453, until the appropriate target dose is achieved. Approximately 60 adult participants with previously R/R CLL/SLL will be enrolled in the study in approximately 40 sites across the world. Participants will receive intravenous (IV) obinutuzumab as part of the debulking period, followed by escalating doses of oral ABBV-453 until the appropriate target dose is achieved. The estimated study duration is 3 years. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, and checking for side effects.
NCT04963296
This parallel-group, double-blind, placebo-controlled study will evaluate the efficacy and safety of obinutuzumab versus placebo in participants with active, autoantibody-positive systemic lupus erythematosus (SLE) who are treated with standard-of-care therapy.
NCT05063435
This study's investigators previously demonstrated the potential utility of non-invasive carotid ultrasonography to calculate carotid intima media thickness (cIMT) and stiffness (as measured by the three parameters, carotid cross-sectional distensibility \[cCSD\], carotid cross-sectional compliance \[cCSC\], and carotid incremental elastic modulus \[cIEM\]) in people with mucopolysaccharidoses (MPS). Investigators also studied arterial gene expression in animal models of MPS, and identified upregulation of a number of markers potentially tied to atherosclerosis and inflammation. These include the atherosclerotic marker known as Clusterin (CLU), Cathepsin S, Elastin, and the inflammatory cytokines interleukin 1-α, interleukin 1-β, interleukin 2, and interleukin 6. Other studies have identified elevation in circulating tumor necrosis factor-α correlating with pain and physical disability in certain mucopolysaccharidoses. Since these studies are cross sectional, and not longitudinal, this study aims to annually measure these previously studied biomarkers (carotid measurements, circulating cytokines, cathepsin S, elastin, and CLU) in a large cohort of MPS patients. This study is a 3-year, prospective, anonymized, longitudinal assessment of cardiovascular structure, function, and circulating biomarkers in patients with mucopolysaccharidoses.
NCT01995058
This study was conducted in subjects in chemotherapy-naïve subjects with bone-metastatic castration-resistant prostate cancer (CRPC).
NCT01696721
In previous studies, Proton Beam Radiation Therapy (PBRT) has been found to show better results in treating patients with cancer, both because there is better control of where in the body the radiation is directed and because it is associated with less severe long term side effects. However, there is limited published data demonstrating these results. The goal of the Proton and Photon Consortium Registry (PPCR) is to enroll children treated with radiation in order to describe the population that currently receives radiation and better compare the short-term and long-term benefits of different types of radiotherapy. The data collected from this study will help facilitate research on radiation therapy and allow for collaborative research. The PPCR will collect demographic and clinical data that many centers that deliver radiation therapy already collect in routine operations.
NCT06425302
The purpose of this study is to assess the efficacy and safety of golcadomide in combination with rituximab in participants with newly diagnosed advanced stage Follicular Lymphoma (FL).
NCT05868148
The goal of the Shoulder iD™ Primary Reversed Glenoid Outcomes Clinical Study is to collect safety and performance data on the commercially available Shoulder iD™ Primary Reversed Glenoid device. The study will learn about standard device use in adult patients who have a functional deltoid muscle and massive and non-repairable rotator cuff tear. The main questions it aims to answer are: * What is the average improvement in patient-reported shoulder function after 2 years when compared to before the surgery, and * What is the rate of surgical revisions needed over a 10 year period Patients will be asked to will be asked to regularly attend their check-up visits with their surgeon (including having x-rays or CT images taken to check their shoulder and implant), to complete questionnaires to report how their shoulder is doing, and to tell their surgeon when they notice any changes.
NCT05006794
This is a Phase I open-label, multi-center study of zamzetoclax (formerly GS-9716) tested either as monotherapy or in combination with other anti-cancer agents in patients with advanced solid malignancies. Primary objectives are to define the maximum tolerated dose (MTD) or maximum administered dose of zamzetoclax, and characterize the safety and tolerability of zamzetoclax as monotherapy and in combination with anti-cancer therapies.
NCT06488144
The aims are to determine whether 1) an incentive based on behaviorally-enhanced gamification and social incentives and 2) health coaching can promote adherence to exercise and physical activity after physical therapy for osteoarthritis of the knee (KOA). The research design is a randomized clinical trial with factorial design This randomized clinical trial of 254 patients using a factorial design will leverage a clinical trial platform developed through the University of Pennsylvania that allows for the remotely capture important patient-reported outcomes and other interaction through a participant's smart phone. The investigators will randomize participants to receive social incentives with gamification to promote adherence to prescribed exercises as well as maintenance of greater levels of physical activity and compare to controls that receive a Fitbit but no additional incentive. Participants may also be randomized to receive a health coach. The investigators will utilize mobile applications for smart phones and wearable activity trackers through the Way-to-Health platform and assess, in real time, the impact of the interventions on patient-reported function and pain (as measured by the Knee Osteoarthritis Outcome Score) as well as physical activity. Participants will be followed for 2 years, with a total of 5 in-person visits. Knee osteoarthritis (KOA) is one of the most prevalent and disabling conditions among Veterans and accounts for high morbidity and high costs for the VA. Importantly, while physical therapy is valuable for patients with KOA, lack of adherence to home exercises and low overall physical activity limit the durability of response. The current proposal aims to address two important knowledge gaps in the management of KOA in order to improve pain and function.
