IVIG for Infection Prevention After CAR-T-Cell Therapy
Recruiting
This phase II trial compares the effects of immunoglobulin replacement therapy with a placebo for preventing infectious complications in patients receiving CD19 chimeric antigen receptor (CAR)-T cell therapy. Hypogammaglobulinemia is a common complication in patients who receive CD19 CAR-T cell therapy. This is a condition in which the level of immunoglobulins (antibodies) in the blood is low and the risk of infection is high. Immunoglobulin replacement therapy works by replacing the body's immu...

Implementation Supports to Reduce Burnout in Therapists Delivering Child Trauma EBPs
Recruiting
The majority of children exposed to early adversity and trauma do not have access to sustainably delivered evidence-based mental health programs (EBPs), despite the growing prevalence of large-scale multiple-EBP implementation efforts aimed at increasing access to these services. The objective of this proposal is to develop and test a package of implementation strategies designed to promote the sustained delivery of child trauma EBPs by reducing provider turnover through targeting the associated...

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

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

This clinical trial tests the effect of induction chemotherapy response-guided radiation (de-escalated intensity-modulated radiation therapy \[IMRT\]) compared to standard IMRT in patients with Epstein-Barr virus (EBV)-associated nasopharyngeal cancer. Intensity-modulated radiation therapy (IMRT) is an advanced form of 3-dimensional radiation therapy that uses computer-generated images to show the size and shape of the tumor. Thin beams of radiation of different intensities are aimed at the tumo... Read More
