Megestrol Acetate Compared With Megestrol Acetate and Metformin to Prevent Endometrial Cancer
Recruiting
This phase II trial studies the effect of megestrol acetate alone or in combination with metformin in preventing the progression of uterine pre-cancer (endometrial intraepithelial neoplasia) to endometrial cancer. Megestrol acetate is a drug used to block estrogen and suppress the effects of estrogen and androgens. It is the current non-surgical treatment of endometrial intraepithelial neoplasia. Metformin is a drug that has been found to have anti-cancer properties. Giving metformin and megestr... Read More

CAR T Cells After Lymphodepletion for the Treatment of IL13Rα2 Positive Recurrent or Refractory Brain Tumors in Children
Recruiting
This phase I trial investigates the side effects of chemotherapy and cellular immunotherapy in treating children with IL13Ralpha2 positive brain tumors that have come back after a period of improvement (recurrent) or do not respond to treatment (refractory). Cellular immunotherapy (IL13(EQ)BBzeta/CD19t+ T cells) are brain-tumor specific cells that may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as as cyclop... Read More

Nephrotic Syndrome Study Network
Recruiting
Minimal change disease (MCD), focal segmental glomerulosclerosis (FSGS), and Membranous nephropathy (MN), generate an enormous individual and societal financial burden, accounting for approximately 12% of prevalent end stage renal disease (ESRD) cases (2005) at an annual cost in the US of more than $3 billion. However, the clinical classification of these diseases is widely believed to be inadequate by the scientific community. Given the poor understanding of MCD/FSGS and MN biology, it is not s...

Evaluation of the Antioxidant and Anti-Inflammatory Capacities of the 'Rosy Red Valencia' and 'Olinda Valencia' Sweet Orange Varieties in Healthy Subjects
Recruiting
This study aims to evaluate the antioxidant and anti-inflammatory effects of acute and chronic consumption of two sweet orange (Citrus sinensis) varieties-'Rosy Red Valencia', which is rich in carotenoids such as lycopene, phytoene, and phytofluene, and 'Olinda Valencia', which lacks these carotenoids-in healthy adults. In this 4-week, randomized, parallel-arm clinical trial, participants will consume either 'Rosy Red Valencia' or 'Olinda Valencia' oranges daily. The study will assess the effect... Read More

Child Bipolar Network Ketogenic Diet Approach to Bipolar Disorder in Adolescents
Recruiting
The present study is an open trial of ketogenic diets for adolescents and young adults (ages 12-21 yrs) in the depressive or mixed phases of bipolar disorder (BD). The investigators aim to determine whether combining standard of care pharmacological treatment for bipolar spectrum disorders with a 16-week ketogenic diet is well-tolerated and associated with improvements in depression, inflammatory and metabolic indicators, and executive functioning over the study period. The experimental treatme... Read More

A Study of Olomorasib (LY3537982) in Participants With Hepatic Impairment and Healthy Participants
Recruiting
The main purpose of this study is to assess how olomorasib gets into the blood stream and how long it takes the body to remove it when administered to participants with mild, moderate and severe impaired liver function compared to participants with normal liver function. The safety and tolerability of olomorasib will also be evaluated. The study may last up to 6 weeks for each participant including the screening period.
