This research aims to understand if sexual activity affects the risk of low blood sugar hypoglycemia in adults with type 1 or type 2 diabetes who use insulin therapy and continuous glucose monitoring CGM. Sexual health is important but often overlooked in diabetes care, and fear of hypoglycemia during or after sexual activity may reduce quality of life. The study addresses this gap using new remote monitoring technology to study glucose changes related to sexual activity. Participants will use CGM systems like LibreView or Dexcom Clarity to track glucose levels during and up to 6 hours after sexual activity, which they mark in their CGM app using a neutral symbol. The study is observational with no assigned treatments participants continue their usual insulin therapy and self-management. Each person will be observed for 3 months, comparing glucose data from sexual activity days to days without sexual activity. During the study, researchers will collect glucose data remotely and receive basic clinical information from healthcare providers. They will analyze the proportion of sexual activity episodes linked to hypoglycemia and compare frequency and mean glucose levels on days with and without sexual activity. Participants data are anonymized and securely handled. The study hopes to help reduce patient fears and guide future recommendations for safe sexual activity with insulin therapy.

Researchers are evaluating whether taking tirzepatide before bariatric surgery can improve health outcomes for people with obesity and related medical conditions. This study aims to see if tirzepatide reduces inflammation in tissues and blood before surgery and how these changes relate to weight loss, metabolic improvements, and fewer complications after surgery. The trial is a Phase 4 interventional study comparing patients who take tirzepatide with those who do not before their planned surgery. Participants who are assigned to the tirzepatide group will self-inject 2.5 mg of tirzepatide once weekly for three months before surgery, following dose escalation instructions if needed. Both groups will receive education on dietary and lifestyle changes. During the three months before surgery, participants will visit the endocrine clinic monthly for drug prescription and side effect monitoring. The study continues through the surgery and post-surgery follow-up periods. Throughout the study, participants will keep a diary of drug use and side effects, and researchers will measure inflammatory markers such as C-reactive protein, interleukin 6, tumor necrosis factor, leptin, adiponectin, and RAAS at baseline, three months after drug use, and several times after surgery. Weight, blood pressure, blood sugar, cholesterol, and surgical complications will also be tracked up to one year after surgery. Participant involvement includes regular clinic visits, lab tests, and monitoring to assess the impact of tirzepatide on surgical outcomes and inflammation.

Researchers are evaluating the use of Gallium-68-DOTATATE PETMRI in patients with somatostatin receptor-positive SSTR-positive central nervous system CNS tumors, mainly focusing on meningioma but also including other tumor types such as esthesioneuroblastoma, hemangioblastoma, medulloblastoma, paraganglioma, pituitary adenoma, and SSTR-positive systemic cancers metastatic to the brain. The study aims to assess the diagnostic usefulness of this imaging technique, especially in distinguishing tumor recurrence from post-treatment changes, with a particular interest in cases where tumor location limits surgical removal or where patients have higher-grade disease or previous radiation treatment. This is a Phase 4 interventional study sponsored by Weill Medical College of Cornell University.

Researchers are studying patients with endogenous Cushing syndrome to understand how often adrenal insufficiency occurs when treated with osilodrostat combined with glucocorticoid replacement. The study also examines new steroid biomarkers to monitor osilodrostat dosing, and assesses treatment durability, safety, and clinical improvement. This observational study aims to provide important insights into managing this condition with a block-and-replace approach. The study has two phases. In Phase 1 Titration, participants start with a low dose of osilodrostat and add methylprednisolone replacement. Doses are adjusted to reach specific cortisol level goals, with frequent monitoring and communication. Once these goals are met, participants enter Phase 2 Maintenance, where they continue treatment for 48 weeks with periodic cortisol tests to track treatment effects. Participants will regularly provide blood and saliva samples for cortisol and steroid profiling, and report symptoms related to adrenal insufficiency. Researchers will track clinical measures such as blood pressure, weight, and quality of life over about 48 weeks. The main outcome is the percentage of participants experiencing adrenal insufficiency during Phase 1, along with various secondary health and hormone measures throughout the study.

Researchers are evaluating the safety and tolerability of GenSci134, a drug given by subcutaneous injection, in healthy adult volunteers and adults with Growth Hormone Deficiency AGHD. This study has two parts the first part involves healthy volunteers in two phasessingle and multiple ascending dosesand the second part includes AGHD patients receiving a single ascending dose. The trial aims to assess safety, how the drug acts in the body pharmacokinetics and pharmacodynamics, immune responses, and other exploratory effects. In the first part, Phase Ia tests single doses of GenSci134 in healthy adult males across seven dose groups with placebo and active controls. Phase Ib evaluates multiple doses in healthy adult males and females in three dose groups. The second part, Phase Ic, studies two dose groups of AGHD patients receiving single doses of GenSci134 compared to active controls. The active comparator is recombinant human growth hormone injection given daily for 28 days. Treatments are given subcutaneously, and the study is randomized and double-blind. Participants will undergo safety assessments including monitoring adverse events for up to three months after dosing. Researchers will collect data on drug absorption, effects on the body, immune response, and tolerability. Healthy volunteers and AGHD patients will be monitored through scheduled visits involving laboratory tests and evaluations to track any side effects and responses to the treatments. The total participation duration varies by study phase and dosing schedule.

The GENESIS clinical study aims to map HLA genetic variation in the Greek population and evaluate possible correlations with selected underlying diseases. It is a multicenter, prospective, non-interventional clinical study targeting 12,000 subjects over an anticipated duration of 36 months, with the goal of creating a pilot HLA map for medical research and possible clinical applications. Each subject will complete one visit at a participating site and provide demographic information, including date of birth, gender, race, ancestry, height, and weight, as well as information about smoking or vaping, alcohol consumption, arterial blood pressure, diagnosed diseases, and current treatments. Recent clinical laboratory results from up to 12 months before sample collection may also be collected when available, including blood count, metabolic, liver enzyme, and biochemical parameters. Two buccal swabs will be collected from each subject for DNA extraction and HLA genotyping analysis. Selected DNA samples will also undergo low-pass whole genome sequencing to further investigate associations between the HLA region and autoimmune diseases. After the analysis is completed, an individualized ancestry report will be securely available to study subjects if they elect to access it.

Researchers are evaluating the effects of Diaberine, a berberine-based nutraceutical, on blood sugar regulation and metabolism in adults with metabolism disorder. This randomized, triple-blind, placebo-controlled trial will study 80 participants aged 18 to 70 over 24 weeks to assess how well this dietary supplement may aid in these health areas. Participants will be randomly assigned to one of two groups. One group will take Diaberine capsules containing Vitamin B12, berberine, magnesium citrate, cinnamon bark extract, chromium, and other ingredients three times daily, 15 minutes before meals. The other group will take placebo capsules with similar appearance but without the active ingredients. Both treatments will continue for 24 weeks with regular monitoring. During the study, participants will have their blood sugar regulation and metabolism measured at baseline, week 12, and week 24. Additionally, quality of life and weight changes will be tracked at multiple points throughout the 24 weeks. Participants will be monitored through questionnaires, blood tests, and weight assessments to evaluate the supplements effects and tolerance over time.

Researchers are evaluating if the drugs Empagliflozin and Semaglutide, alone or combined, can improve blood sugar control by increasing time-in-range in adults with Type 1 Diabetes who use Automated Insulin Delivery AID systems. This study also monitors the safety of these drugs in this setting. It is a randomized, double-blind, placebo-controlled Phase 3 crossover trial designed to compare the effects of these treatments in the same participants. Participants will receive four different treatment combinations through a crossover design semaglutide injection plus empagliflozin tablet, semaglutide injection plus placebo tablet, placebo injection plus empagliflozin tablet, and placebo injection plus placebo tablet. Semaglutide is given by weekly subcutaneous injection with a 12-week dose escalation period to reach a stable dose. Empagliflozin or its placebo is taken daily by tablet. Washout periods between treatments help avoid carryover effects. During the study, participants will use their personal AID systems continuously while researchers collect continuous glucose monitoring data to measure time-in-range and other blood sugar outcomes. Questionnaires will assess diabetes distress and treatment satisfaction after each intervention period. Safety is closely monitored throughout, including tracking adverse events and providing rescue medications for low blood sugar. The entire participation involves multiple treatment periods with careful monitoring and data collection.

Researchers are evaluating the safety, pharmacokinetics, pharmacodynamics, and effectiveness of an investigational drug called GNR-055 in patients with Mucopolysaccharidosis Type II MPS II, also known as Hunter syndrome. This condition is a genetic disorder caused by a deficiency of the enzyme iduronate-2-sulfatase ID2S, leading to harmful buildup of certain substances in cells that affects growth, organs, and the nervous system. The study is a phase 23, multicenter, open-label trial involving different age groups to better understand how GNR-055 works and its safety profile. GNR-055 is a modified enzyme replacement therapy designed to cross the blood-brain barrier, potentially preventing neurological damage and improving quality of life for patients with MPS II. Participants receive weekly intravenous infusions of GNR-055 at doses ranging from 1.0 to 3.0 mgkg, depending on their study group. The study includes multiple cohorts, with adult and pediatric patients receiving specific dosing regimens over the trial period. During the study, participants will undergo various assessments including monitoring of adverse events, urine and serum levels of glycosaminoglycans GAG, cerebrospinal fluid analysis, joint motion measurements, MRI scans of liver, spleen, and brain, heart and lung function tests, neurocognitive evaluations, and biomarker analysis. These evaluations occur at baseline and multiple follow-up visits up to week 56. The study aims to gather detailed data on the drugs impact on disease symptoms, safety, and biological markers to inform future treatment options.

Researchers are investigating how metabolism, body composition, and body surface area relate in both healthy individuals and those with metabolic conditions such as diabetes, obesity, renal disease, or cancer. The study aims to improve the accuracy of metabolic rate measurements, which have traditionally relied on simple formulas using height and weight, which may not work well for everyone. Participants will spend two days and one night in the hospital during each visit. They will provide medical history, answer questions about their activity, diet, and lifestyle, and consume a special diet. They will undergo various tests including breathing gas measurements while lying under a clear hood, body scanning on a padded table and with a 3D scanner, electrical signal speed testing through the body, hand strength measurement, and collection of blood and urine after drinking salty water. Participants may return up to eight times per year with at least two weeks between visits. During the study, participants will be evaluated through these tests and questionnaires to understand their resting energy expenditure and body measurements. The primary outcomes include comparing measured versus predicted body surface area and determining how measured body surface area relates to energy expenditure independent of body composition. The study will continue until July 2031, and participants health and ability to complete tests will be monitored throughout their involvement.
