Early Metabolic Effects of Dolutegravir or Tenofovir Alefenamide in Healthy Volunteers
NCT05652478
Recruiting
Background: People with HIV take drugs to keep the amount of virus in their body low. One type of these drugs, called integrase strand transfer inhibitors (INSTIs), can cause weight gain over time. Weight gain can cause diabetes, heart disease, and other serious issues. Researchers want to understand how INSTIs cause weight changes. Objective: To see how a common INSTI, dolutegravir (DTG), affects how the body uses energy. DTG will be compared with a non-INSTI drug, tenofovir alafenamide (TAF... Read More

Nivolumab in Epstein-Barr Virus (EBV)-Positive Lymphoproliferative Disorders and EBV-Positive Non-HodgkinLymphomas
NCT03258567
Recruiting
Background: The drug Nivolumab has been approved to treat some cancers. Researchers want to see if it can slow the growth of other cancers. They want to study its effects on cancers that may have not responded to chemotherapy or other treatments. Objectives: To see if Nivolumab slows the growth of some types of cancer or stops them from getting worse. To test the safety of the drug. Eligibility: People 12 and older who have Epstein-Barr Virus (EBV)-positive lymphoproliferative disorders or... Read More

18F-Fibroblast Activation Protein Inhibitor ([18F]FAPI-74) PET Imaging for Cancer Detection
NCT06503146
Recruiting
Background: Fibroblast-activation protein (FAP) is an enzyme that appears in high numbers in cancer-associated fibroblasts of certain cancer types. \[18F\]FAPI-74 is a new PET (positron emission tomography) tracer, a substance that is injected into a person s body before an imaging scan. Researchers believe that \[18F\]FAPI-74 PET imaging may be able to visualize cancer more effectively than the approved tracers. If so, the new tracer would make it easier to find FAP-positive tumors in the body... Read More

Urinary Vitamin C Loss in Diabetic Subjects
NCT00071526
Recruiting
Several studies have reported that diabetic subjects have lower plasma vitamin C concentrations than non-diabetic subjects. Although urinary vitamin C loss in diabetic subjects was reported to be increased in two studies, these are difficult to interpret due to lack of controlled vitamin C intake, inadequate sampling, lack of control subjects, or methodology uncertainties in vitamin C assay and sample processing. Consequently, it is unclear whether diabetic subjects truly have both low plasma an... Read More

A Phase I/II Study of Zotiraciclib for Recurrent Malignant Gliomas With Isocitrate Dehydrogenase 1 or 2 (IDH1 or IDH2) Mutations
NCT05588141
Recruiting
Background: Diffuse gliomas are tumors that affect the brain and spinal cord. Gliomas that develop in people with certain gene mutations (IDH1 or IDH2) are especially aggressive. Better treatments are needed. Objective: To see if a study drug (zotiraciclib) is effective in people with recurrent diffuse gliomas who have IDH1 or IDH2 mutations. Eligibility: People aged 15 years and older with diffuse gliomas that returned after treatment. They must also have mutations in the IDH1 or IDH2 gene... Read More

Magnetic Resonance Imaging (MRI) to Evaluate Activity of Multiple Sclerosis (MS)
NCT00001248
Recruiting
Studies performed under 89-N-0045 are designed to examine the natural history of multiple sclerosis (MS) using MRI and immunological measures. In addition to studying the natural history of untreated patients, the natural history of patients receiving approved disease-modifying therapies of MS will be examined. In both cohorts of patients levels of disease activity on MRI will be compared with immunological characteristics in order to help identify disease mechanism. Patients with either definit...

Studying the Safety and Determining the Optimal Dose of Novobiocin in Patients With Tumors That Have Alterations in DNA Repair Genes
NCT05687110
Recruiting
This phase I trial tests the safety, side effects, and best dose of novobiocin in treating cancer patients with alterations in deoxyribonucleic acid (DNA) repair genes. Novobiocin is an antibiotic that blocks the activity of a protein called DNA polymerase theta, which helps repair DNA that has become damaged as cells grow and divide. Cancer cells that cannot repair their damaged DNA die. This medication may help shrink or stabilize cancer with a mutation in DNA repair genes.

Diagnosis of Pheochromocytoma
NCT00004847
Recruiting
The goal of this study is to develop better methods of diagnosis, localization, and treatment for pheochromocytomas. These tumors, which usually arise from the adrenal glands, are often difficult to detect with current methods. Pheochromocytomas release chemicals called catecholamines, causing high blood pressure. Undetected, the tumors can lead to severe medical consequences, including stroke, heart attack and sudden death, in situations that would normally pose little or no risk, such as surge... Read More
