Dallas, TX Paid Clinical Trials

The study is designed to use infusion of a non-radioactive, naturally occurring isotope of glucose (13C) in patients undergoing surgical resection for a newly identified brain mass to obtain the metabolic phenotype of the tumor, and correlate it with the histopathological diagnosis. In each patient, 13C NMR spectral analysis of tumor extracts will be obtained after intraoperative infusion of \[U-13C\]glucose or \[1,2-13C\]glucose. Whenever feasible, patients will undergo 3 preoperative imaging studies - 18FDG-PET, diffusion tensor imaging with 1H-spectroscopy on 3T MR scanner, and ultra high resolution MR imaging on the 7T MR scanner. The results of these imaging studies will be correlated with the metabolic phenotype to generate a comprehensive non-invasive view of the tumor with the goal of identifying infiltrative, metabolically active tumor cells within the brain. In addition, a comprehensive molecular profile of the tumor will be obtained and enable a genotype-metabolic phenotype comparative analysis. Correlative Translational Research The investigators will obtain tumor tissue from each patient for comprehensive molecular analysis (array CGH, expression profiling, methylation profiling) which will be correlated with tumor histology, the metabolites identified by 1H-MR spectroscopy and the 13Cglucose metabolic profile. Patients will be followed at designated time points along their treatment course to obtain information about ongoing treatment and response, time to tumor progression and overall survival. These parameters will be used in correlational analysis with the metabolic phenotype. Read Less

The goal of this trial is to test if colonization with the gut bacteria Oxalobacter formigenes leads to a reduction in urinary oxalate excretion in patients with calcium oxalate kidney stone disease. The study will recruit adult participants with a history of calcium oxalate kidney stones who are not colonized with Oxalobacter formigenes. Participants will * ingest fixed diets containing low and moderately high amounts of oxalate for 4 days at a time * collect urine, blood and stool samples during the fixed diets * ingest a preparation of live Oxalobacter formigenes to induce colonization with Oxalobacter formigenes Read Less

Pentoxifylline (PTX) is a medication that has been on the market since 1984 for use in disease in the blood vessels of the legs. There is some preliminary information that it may protect the kidneys from damage due to diabetes and other diseases. "Pentoxifylline in Diabetic Kidney Disease" is a study to bee conducted in 40 VA hospitals across the nation to determine definitively whether or not PTX can prevent worsening of kidney disease and delay death in patients with diabetic kidney disease.

The goal of this clinical trial study is to test if patients with idiopathic calcium oxalate kidney stones have an increased absorption of dietary oxalate, which would lead to increased urinary excretion of oxalate. The study will recruit adult patients with a history of calcium oxalate kidney stones and healthy volunteers without kidney stones. Participants will * ingest fixed diets containing low and moderately high amounts of oxalate for 5 days at a time * ingest a soluble form of oxalate and sugar preparations to test gut permeability * collect urine, blood, stool and breath sample during the fixed diets and the soluble oxalate test Read Less

This is a phase 3, open-label, randomized, multi-center study assessing the efficacy and safety of DZD9008 versus platinum-based doublet chemotherapy in participants with locally advanced or metastatic NSCLC with EGFR Exon20ins mutation, who are newly diagnosed or have not received prior systemic therapy in advanced stage. Primary objective of this study is to assess the efficacy of DZD9008 versus platinum-based doublet chemotherapy using by BICR-assessed PFS per RECIST 1.1 as primary endpoint. Approximately 320 participants are estimated to be randomized into the study. Participants enrolled will be randomized to DZD9008 or platinum-based doublet chemotherapy in a 1:1 manner, stratified by baseline brain metastasis (with/without). Read Less

The purpose of this study is to evaluate the antiviral effect, safety, tolerability, and pharmacokinetics of STP0404 in adult participants living with Human Immunodeficiency Virus Type 1 (HIV-1) infection. Read Less

Subjects with relapsed large cell lymphoma will receive 3 cycles of combination therapy consisting of GDP and epcoritamab. Each cycle will last 21 days. GDP consists of gemcitabine 1000 mg/m2 IV on Days 1 and 8, cisplatin 75 mg/m2 IV on Day 1, and dexamethasone 40 mg orally on Days 1 through 4. Epcoritamab will be administered subcutaneously (SC) on Days 1, 8, and 15. Patients will receive granulocyte colony stimulating factor (G-CSF) between Day 8 through Day 10 of each cycle of combination therapy. Patients will then undergo radiology imaging for disease assessment. Patients may proceed to SCT(autologous or allogeneic) or CAR T-cell therapy or epcoritamab monotherapy upon completion of Cycle 3 per investigator discretion. The rationale for subjects not proceeding to autoSCT or CAR T-cell therapy will be captured in the eCRFs. Patients who do not undergo SCT or CAR T-cell therapy may have the option to receive study treatment with epcoritamab monotherapy following completion of Cycle 3. Epcoritamab monotherapy will be offered to selected subjects who become ineligible to undergo SCT or CAR T-cell therapy (such as social situation, change in subject decision). The decision to offer epcoritamab monotherapy will be per investigator's discretion. However, subjects must have demonstrated a response to the combination therapy (partial remission or complete remission) per disease assessment scans prior to offering epcoritamab monotherapy. Epcoritamab monotherapy should begin 2 weeks following Cycle 3 Day 15. Monotherapy will consist of epcoritamab 48 mg administered subcutaneously on Days 1 and 15 of each 28 day cycle for Cycle 4 to Cycle 9 or until unacceptable toxicity, or disease progression per the Lugano Criteria.

This study is trying to find the right dose of a long-lasting medicine called GSK5784283 for people with asthma that remains uncontrolled even though they are using regular asthma treatments. GSK5784283 blocks the action of an inflammatory protein called TSLP that may be contributing to your asthma. The study will be conducted in two parts - Part A (dose finding phase) and Part B (extended dosing phase). Part A will assess the lung function, asthma control, participant safety and certain markers of asthma inflammation in the air you breath out and in your blood. Part B will assess the safety and long-term effects of the repeated or single doses of GSK5784283. Read Less

The primary purpose of the study is to determine if IVT injections of ANX007 every month reduce vision loss in participants with GA secondary to age-related macular degeneration (AMD). Read Less

RATIONALE: Collecting and storing samples of tissue from patients with cancer to test in the laboratory may help the study of cancer in the future. PURPOSE: This research study is collecting tissue samples from patients with cancer undergoing radiation therapy. Healthy participants will also be allowed on the trial so their samples can be used in comparison to patients with malignancy Read Less
