Filter by:This Phase 2 single arm trial in patients with rGBM will characterize the efficacy, safety, tolerability and initial efficacy of lerapolturev intratumoral infusion followed by intravenous pembrolizumab 14 to 28 days later, and every 3 weeks, thereafter.
The purpose of this study is to determine if a combination of two drugs ipatasertib and atezolizumab works as a treatment for residual cancer in the breast or lymph nodes and have circulating tumor DNA in the blood. This research study involves the following investigational drugs: - Sacituzumab govitecan - Atezolizumab
The proposed studies will test this hypothesis by randomizing patients with AF to 2-HOBA or placebo 7 days prior to AF ablation to allow 2-HOBA to reach steady-state levels. We hypothesize that tissue injury from AF ablation causes a large release of ROS that react with lipids to generate IsoLGs (Figure 2). In the absence of 2-HOBA, IsoLGs will react within seconds to form IsoLG-macromolecule adducts in atrial tissue, promoting early recurrence of AF. In the presence of 2-HOBA, IsoLGs will rapidly react to form IsoLG-macromolecule adducts in atrial tissue, promoting early recurrence of AF. In the presence of 2-HOBA, IsoLG will preferentially bind to and therefore be inactivated by 2-HOBA thereby sparing injury to the atrial tissue caused by oxidative stress and its contribution to early recurrence of AF. Early recurrence of AF will be measured by ECGs that are recorded once per day by a smartwatch (Apple Watch, Apple Inc., Cupertino, CA) with additional ECGs recorded by the participant if they experience symptoms of AF, or if the smartwatch alerts the participant of a possible AF episode via its auto-detection AF monitoring algorithm. The Apple Watch's AF algorithm is based on sampling of heart rate and variability and will give an audible alarm if those parameters indicate a possible episode of AF. The smartwatch records a single-lead ECG if the participant touches the watch with their contralateral hand. The day and time of the episode is also stored by the smartwatch. At the end of the 28-day follow-up period, study personnel will review the stored ECGs. Blood will be drawn prior to ablation and on post-procedure Day 1 for measurement of IsoLG-adduct levels. DNA will be extracted to explore a pharmacogenomic interaction with haplotypes at the chromosome 4q25 AF risk locus, which: 1) is strongly associated with the development of AF and the early recurrence of AF after ablation27; and 2) has been reported to be a regulator of an anti-oxidant gene program in response to cardiac injury.
This research study is studying a new viral cancer therapy, ofranergene obadenovec (VB-111), for recurrent or progressive glioblastoma (GBM), a brain tumor that is growing or progressing despite earlier treatment.
This is an open-label, single center, pilot trial to evaluate the safety and efficacy of toripalimab and gemcitabine in patients with recurrent or metastatic nasopharyngeal carcinoma.
This phase II trial studies the side effects and how well brachytherapy with durvalumab or tremelimumab work for the treatment of gynecological malignancies that is resistant to platinum therapy (platinum-resistant), does not respond to treatment (refractory), has come back (recurrent), or has spread to other places in body (metastatic). Brachytherapy, also known as internal radiation therapy, uses radioactive material placed directly into or near a tumor to kill tumor cells. Immunotherapy with monoclonal antibodies, such as durvalumab and tremelimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. This trial is being done to see whether brachytherapy with durvalumab or tremelimumab works better in treating patients with gynecological malignancies.
Introduction: Orthodontic retainers are used after the completion of orthodontic treatment to assure dental occlusal stability and to maintain the achieved end-result. However, without retention teeth could go back to their initial dental malposition or could even take a different unpredicted position resulting once again in dental malocclusion (a deviation from normal occlusion). There are different types of retainers, some are fixed (glued to the back of the front teeth), and others are removable (can be removed and replaced into the mouth by the patient). While there are various retainers used for retention (stability), there is no perfect method. Fixed retainers (FRs) are used worldwide. On the one hand, FRs focus on preventing relapse. On the other hand, there are sometimes some adverse effects of retainers; they could fail at a certain point (break/get loose), or cause unwanted tooth movements. Until now, the choice of a retention method is based solely on clinicians' experience as there is no substantial evidence regarding the best retention method or the duration of the retention period. Some clinicians prolong the retention period while others prefer to keep the retainers for an indefinite time. As the world is advancing, so is the orthodontic science. New FR fabricated by CAD/CAM (Computer-Aided Design/Computer-Aided Manufacturing), are assumed to have greater accuracy, better fit, and most importantly, might offer a passive positioning of the retainer. However, the evidence about CAD/CAM FRs is very limited. Purpose: To investigate and compare the clinical effectiveness of two types of FRs; CAD/CAM vs. multistranded wire, in terms of stability (primary outcome), failure rate, adverse effects, cost-effectiveness, and patient satisfaction (secondary outcomes), substantial up to 5 years after retainer placement. Hypotheses: Compared to traditional multistranded FRs, CAD/CAM FRs have: - Better long term stability, - Similar failure rate, - Fewer adverse effects, - Similar cost-effectiveness and patient satisfaction.
This is a phase II open-label study investigating the efficacy, safety and pharmacokinetic(PK) properties of OKN-007 combined with temozolomide(TMZ) in patients with recurrent glioblastoma(GBM). All patients will have been previously treated with the standard-of-care treatment which includes surgical resection, radiation and chemotherapy, and in some cases treatment for recurrent disease. Patients with unequivocal recurrence (first or greater) established by MRI and meeting inclusion and exclusion criteria, will be eligible for OKN-007 treatment on this protocol.
This is a multi-center, prospective, controlled study. MS patients (1° group: 30 patients in relapse; 2° group: 30 patients in remission) and age/sex-matched healthy controls (3° group: 30 subjects) will be enrolled in the study. Patients' disability level will be evaluated by EDSS and MSFC. Patients and controls will be tested for either coagulation/complement (C3, C4, C4a, C9, fibrinogen, factor VIII and X, D-dimer, protein C, protein S, antithrombin, factor II, aPTT, von-Willebrand factor), soluble markers of endothelial damage (thrombomodulin, Endothelial Protein C Receptor), antiphospholipid antibodies, lupus anticoagulant, complete blood count, viral serological assays or microRNA microarray. Patients will undergo dynamic susceptibility contrast-enhanced MRI using a 3.0-T scanner to evaluate CBF, CBV, MTT, lesion number and volume.
This phase II pediatric MATCH treatment trial studies how well selpercatinib works in treating patients with solid tumors that may have spread from where they first started to nearby tissue, lymph nodes, or distant parts of the body (advanced), lymphomas, or histiocytic disorders that have activating RET gene alterations. Selpercatinib may block the growth of cancer cells that have specific genetic changes in an important signaling pathway (called the RET pathway) and may reduce tumor size.
