NCT02932956
This study enrolls patients who have GPC3-positive solid tumors currently. Patients may be considered if the cancer has come back, has not gone away after standard treatment or the patient cannot receive standard treatment. This research study uses special immune system cells called GAP T cells, a new experimental treatment. The body has different ways of fighting infection and disease. No single way seems perfect for fighting cancers. This research study combines two different ways of fighting cancer: antibodies and T cells. Antibodies are types of proteins that protect the body from infectious diseases and possibly cancer. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells, including cells infected with viruses and tumor cells. Both antibodies and T cells have been used to treat patients with cancers. They have shown promise, but have not been strong enough to cure most patients. Investigators have found from previous research that they can put a new gene into T cells that will make them recognize cancer cells and kill them. In preclinical studies, the investigators made several genes called a chimeric antigen receptor (CAR), from an antibody called GC33 that recognizes glypican-3, a proteoglycan found on solid tumors including pediatric liver cancers (GPC3-CAR). This study will test T cells genetically engineered with a GPC3-CAR (GAP T cells) in patients with GPC3-positive solid tumors (currently only enrolling liver tumors). The GAP T cells are an investigational product not approved by the Food and Drug Administration. The purpose of this study is to find the biggest dose of GAP T cells that is safe, to see how long they last in the body, to learn what the side effects are and to see if the GAP T cells will help people with GPC3-positive solid tumors. This study enrolls patients who have GPC3-positive solid tumors (currently only enrolling liver tumors).
NCT04857372
The purpose of this study is to characterize the safety and tolerability of IAG933 in patients with mesothelioma, NF2/LATS1/LATS2 mutated tumors and tumors with functional YAP/TAZ fusions and to identify the maximum tolerated dose and/or recommended dose.
NCT04079179
This is a research study of a drug called cobimetinib in children and adults diagnosed with Langerhans cell histiocytosis (LCH), and other histiocytic disorders that has returned or does not respond to treatment. Cobimetinib blocks activation of a protein called Mitogen-activated protein kinase (MEK) that is part of incorrect growth signals in histiocytosis cells. Four different groups of patients will be enrolled.
NCT05340881
Children and adolescents treated for a brain tumor often experience fatigue and cognitive symptoms, such as slowed information processing and inattention. These symptoms may cause difficulty carrying out daily activities at home and at school. There are few well-researched, non-pharmacological interventions aimed at improving symptoms of fatigue and by extension cognitive symptoms. Systematic bright light exposure has been shown to improve symptoms of fatigue in adult survivors of cancer and children treated for some forms of cancer. This is a pilot/feasibility study and the first known study in children treated for a brain tumor. Findings from this study will be used to help plan a larger study to examine the effectiveness of this intervention and mechanisms of action. PRIMARY OBJECTIVE: 1. To evaluate feasibility and adherence in a study of systematic bright light exposure used to improve fatigue and cognitive efficiency in survivors of pediatric brain tumor, including rates of enrollment, adherence, and acceptability. SECONDARY OBJECTIVES: 2. To estimate the effect size of change in fatigue associated with bright light exposure. 3. To estimate the effect size of change in cognitive efficiency associated with bright light exposure.
NCT03011814
This randomized phase I/II trial studies the best dose and side effects of durvalumab and to see how well it works with or without lenalidomide in treating patients with cutaneous or peripheral T cell lymphoma that has come back and does not respond to treatment. Monoclonal antibodies, such as durvalumab, may interfere with the ability of cancer cells to grow and spread. Drugs used in chemotherapy, such as lenalidomide, 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. Giving durvalumab and lenalidomide may work better in treating patients with cutaneous or peripheral T cell lymphoma.
NCT05382286

NCT04762680
The primary objectives of the study are: To assess the safety profile of the study vaccines in each study intervention group. To assess the neutralizing antibody profile after primary series vaccination in SARS-CoV-2-naïve adults. To demonstrate that a booster dose of monovalent or bivalent SARS-CoV-2 vaccine given to adults previously vaccinated with an authorized/approved COVID-19 vaccine induces an immune response that is non-inferior to the response induced by a twodose priming series with the monovalent vaccine, and superior to that observed immediately before booster. The secondary objectives of the study are: To assess the neutralizing and binding antibody profiles after primary series vaccination at pre-defined time points during the study. To assess the neutralizing and binding antibody responses of booster vaccination. To describe the occurrences of laboratory-confirmed symptomatic COVID19 after primary series and booster vaccination. To describe the occurrences of serologically-confirmed SARS-CoV-2 infection after primary series vaccination.
NCT05658510

NCT03289780
The purpose of this study is to collect information about how a doctor uses the results of the VeriStrat® blood test to guide treatment for non-small cell lung cancer (NSCLC) patients. Understanding how VeriStrat test results influence doctors' decisions and patients' outcomes may help doctors to better treat NSCLC in the future. This study will also look to establish whether new investigational tests can help better predict the effectiveness of certain medications for certain patients. These new investigational tests are only for research purposes at this time.

NCT02563327
The Tuberculosis Trials Consortium (TBTC) phase 3 treatment trial, Study 31, will investigate the efficacy and safety of daily rifapentine (1200 mg daily) with or without moxifloxacin as part of multidrug treatment regimens for drug-sensitive pulmonary TB. The proposed study (Study 31 PK/PD) will examine the population pharmacokinetics and pharmacodynamics (PK/PD) of high-dose daily rifapentine with and without moxifloxacin given for 17 weeks. Two different PK sampling procedures are required for the population PK/PD assessments involving rifapentine and moxifloxacin: (1) intensive sampling of 6 samples/participant on one occasion plus subsequent sparse sampling for a subset of Study 31 participants who are invited to co-enroll in Study 31 PK/PD; and (2) sparse sampling of 2-3 samples/participant for all other Study 31 trial participants (these data will be collected as part of the Study 31 treatment protocol). Herein, we describe the PK sampling to be conducted among those Study 31 participants who are co-enrolled to Study 31 PK/PD (n=60). Intensive PK sampling is needed in some participants to estimate the population PK model parameters with no bias and satisfactory precision (relative standard error \< 20%). PK and outcomes data from all participants in Study 31 will be merged to build the population PK/PD models to evaluate PK/PD parameters. Details regarding these planned analyses are also provided in this Study 31 PK/PD protocol. Primary Objectives: 1. Characterize the population pharmacokinetics of rifapentine and 25-desacetyl rifapentine, using sparse PK data from Study 31 and intensive PK data from Study 31 PK/PD. Using the population PK model, determine post-hoc Bayesian estimates of individual-level PK parameters. 2. Examine the relationship between rifapentine PK parameters of interest and treatment efficacy. PK parameters will include area under the concentration time curve (AUC0-24), peak concentration (Cmax), time above the mean inhibitory concentration (MIC), and AUC/MIC. The treatment outcome of interest will be time to culture conversion and time to treatment failure or relapse. Secondary Objectives: 3. Among the Study 31 participants in the lowest 10% for rifapentine AUC0-24, examine the PK/PD effect on culture conversion of sputa after completion of 4 months of daily rifapentine therapy. 4. Examine the relationship between safety outcomes (Grade 3 or higher adverse events) and rifapentine PK parameters (AUC0-24, Cmax, AUC0-24/MIC and time above MIC). 5. Characterize the population PK of moxifloxacin, and then estimate moxifloxacin AUC0-24 and Cmax when moxifloxacin is administered with rifapentine given at a daily dose of 1200 mg. 6. Examine the relationships between moxifloxacin PK and treatment outcomes (as described in objective 2 for rifapentine) and moxifloxacin PK and safety (as described in objective 4 for rifapentine). Design: In Study 31 PK/PD, among 60 participants with tuberculosis enrolled in a rifapentine-based treatment arm of Study 31, PK data will be collected on two occasions. At TBTC sites that have the capacity to perform this activity, participants will have 6 scheduled PK samples per participant collected to measure rifapentine (with or without moxifloxacin) concentrations over approximately 24 hours. In addition among these 60 participants, 2 to 3 scheduled PK samples will be obtained on a second "late" sampling at \> 14 days after the first PK sampling.
NCT03971071
Study 20170703 is a phase 4, randomized, double-blind, parallel-group, placebo-controlled study to evaluate the efficacy and safety of erenumab against placebo in participants with chronic migraine (CM) who have a history of at least 1 preventive treatment failure and are diagnosed with medication overuse headache (MOH).
NCT05079035
It is hypothesized that a single Intra-articular Injection of TTAX03, 100mg in 2mL of saline, will have more benefit with respect to the proportion of responders 12 weeks post-injection than an equal volume of saline, based on the OMERACT-OARSI responder criteria.
NCT06131424
This noninterventional, multicenter,retrospective study has been proposed to estimate the prevalence, clinicopathological characteristics,treatment patterns and clinical outcomes of human epidermal growth factor receptor 2 -(HER2)low locally-advanced or metastatic breast cancer(mBC) by accurate rescoring of archived IHC-stained formalin-fixed paraffin-embedded (FFPE) slides for HER2 in patients previously identified as HER2-negative from emerging markets of international regions (non-US and non-European region) with largely unknown prevalence estimates of HER2 low mBCs. Patients with a confirmed diagnosis of HER2-negative, locally-advanced or mBC regardless of Hormone receptor (HR)status between 01 January 2019 and 31 December 2022 who progressed on any systematic anticancer therapy (eg, ET, chemotherapy, CDK4/6 inhibitor, targeted therapies other than anti-HER2, or immunotherapy) in advanced disease with availability of atleast 12 months of follow-up data (from the index date) in the medical records at the participating site, unless patient died within the first 12 months of diagnosis of locally-advanced or mBC will be enrolled in the study. The HR positive patients will be considered eligible for the study if they have received ET as adjuvant therapy in the early BC setting and progressed within 24 months. This scenario will be considered as progression on systematic treatment in the advanced or metastatic setting.
