Metformin for the Treatment of Insulin Resistance in Women With Stage I-III Breast Cancer Completing Chemotherapy
NCT06763328
Recruiting
This phase III trial evaluates how often women develop insulin resistance and type-2 diabetes and compares metformin with usual care to usual care alone in treating insulin resistance in women with stage I-III breast cancer after chemotherapy. Insulin resistance occurs when cells stop responding to insulin and is a risk factor for developing diabetes and heart disease. Higher levels of insulin have been shown to be associated with aggressive breast cancer. Metformin hydrochloride decreases the a... Read More

Examination of Nociscan Impact on Discogenic Low Back Pain Surgical Outcomes
NCT06661850
Recruiting
This study is looking into how safe and useful NOCISCAN is. NOCISCAN is a software as a Service (SaaS) tool that uses Magnetic Resonance (MR) spectroscopy. Nociscan (instead of 'It') leverages MRS to noninvasively help physicians distinguish between painful and nonpainful discs in the lumbar spine. The randomized controlled trial will compare the blinded and unblinded cohorts and their corresponding surgical outcomes with the Nocigram reports, generated prior to treatment, for each patient."

Safety and Efficacy of a Drug Eluting Slim Modiolar Electrode Array
NCT06598059
Recruiting
This clinical study will test a new type of cochlear implant known as CI632D. This experimental cochlear implant has been designed to slowly release a drug called dexamethasone. Dexamethasone works to ease inflammation and reduce tissue injury, which is common after any type of surgery. The goal is to learn if the dexamethasone in the CI632D implant lessens these reactions inside the ear following surgery and if this makes the implant work as well, or even better, in improving hearing than what...

A Study of Efficacy and Safety of Sacituzumab Tirumotecan (MK-2870) Plus Enfortumab Vedotin (EV) With and Without Pembrolizumab in Advanced Urothelial Carcinoma (MK-3475-04C/KEYMAKER-U04)
NCT06483334
Recruiting
This study is a substudy being conducted under one pembrolizumab umbrella master study KEYMAKER-U04. The substudy will consist of 2 parts. Part 1 will evaluate the safety and preliminary efficacy of sacituzumab tirumotecan plus enfortumab vedotin (EV). Part 2 will be based on Part 1 results and will evaluate the efficacy, pharmacokinetics, and safety of sacituzumab tirumotecan plus EV in combination with pembrolizumab in participants with advanced urothelial carcinoma.

Social Facilitation of Emotion Regulation in Adolescence
NCT06458920
Recruiting
The goal of this project is to test whether regulating emotions with help from a friend is more effective and long-lasting in adolescents than regulating alone, and to characterize age-related differences in the neural mechanisms supporting social versus cognitive emotion regulation. Participants will complete a psychology experiment while undergoing fMRI scanning.

Impact of Sodium Bicarbonate on 24-hour Urine Parameters in Hypocitriuric and Uric Acid Stone Formers
NCT06335537
Recruiting
The incidence of kidney stone disease continues to rise globally. Although the treatment of kidney stone disease has dramatically improved in recent years, surgical management remains invasive and expensive. Patients who develop kidney stones are at high risk of recurrence during their lifetime; therefore, prevention of stones should be a primary focus. Low levels of citrate and acidic urine are risk factors for the formation of kidney stones such as calcium oxalate and uric acid, respectively.... Read More
