Pembrolizumab Plus CA-4948 for the Treatment of Patients With Progressive Metastatic Urothelial Cancer Despite Prior Immunotherapy
Recruiting
This phase I trial tests the safety, side effects, best dose, and effectiveness of emavusertib (CA-4948) in combination with pembrolizumab in treating patients with urothelial cancer that has spread from where it first started to other places in the body (metastatic) and that has a resistance to PD-1/PD-L1 immune checkpoint inhibitors. CA-4948, a kinase inhibitor, may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies,... Read More

RECOVER-SLEEP: Platform Protocol
Recruiting
The platform protocol is designed to be flexible so that it is suitable for a range of study settings and intervention types. Therefore, the platform protocol provides a general protocol structure that can be shared by multiple interventions and allows comparative analysis across the interventions. For example, objectives, measures, and endpoints are generalized in the platform protocol, but intervention-specific features are detailed in separate appendices. This platform protocol is a prospect... Read More

Comparing Rituximab and Mosunetuzumab Drug Treatments for People With Low Tumor Burden Follicular Lymphoma
Recruiting
This phase III trial compares the effectiveness of rituximab to mosunetuzumab in treating patients with follicular lymphoma with a low tumor burden. Rituximab is a monoclonal antibody. It binds to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cells. Mosunetuzumab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. It is not yet known if giving r... Read More

Venetoclax and HMA Treatment of Older and Unfit Adults With FLT3 Mutated Acute Myeloid Leukemia (AML) (A MyeloMATCH Treatment Trial)
Recruiting
This phase II MyeloMATCH treatment trial compares the usual treatment of azacitidine and venetoclax to the combination treatment of azacitidine, venetoclax and gilteritinib in treating older and unfit patients with acute myeloid leukemia and FLT3 mutations. Azacitidine is a drug that is absorbed into DNA and leads to the activation of cancer suppressor genes, which are genes that help control cell growth. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may... Read More

iMmune SignAtures and Clinical outComes in AP
Recruiting
The MoSAIC study is a prospective, observational study designed to develop an early prediction tool for severe acute pancreatitis (SAP) and define a distinct immunologic profile compared to moderate acute pancreatitis (MAP). The aims are to validate a new multi-cytokine panel for early prediction of SAP and to identify the specific immune cells that correspond with cytokine signatures in early acute pancreatitis to characterize the immune pathways driving the development of SAP. Participants wil... Read More

A Study to Compare Standard Therapy to Treat Hodgkin Lymphoma to the Use of Two Drugs, Brentuximab Vedotin and Nivolumab
Recruiting
This phase III trial compares the effect of adding immunotherapy (brentuximab vedotin and nivolumab) to standard treatment (chemotherapy with or without radiation) to the standard treatment alone in improving survival in patients with stage I and II classical Hodgkin lymphoma. Brentuximab vedotin is in a class of medications called antibody-drug conjugates. It is made of a monoclonal antibody called brentuximab that is linked to a cytotoxic agent called vedotin. Brentuximab attaches to CD30 posi... Read More

Trial of Suvorexant for Sleep in Children With Autism
Recruiting
The purpose of this study is to examine the effect of suvorexant on sleep in children and adolescents with Autism Spectrum Disorder (ASD). Suvorexant is a selective, dual orexin receptor antagonist (DORA) used for the treatment of sleep onset difficulties and/or sleep maintenance. To accomplish this, the investigators will use a randomized double-blind placebo-controlled crossover 8-week study design to examine the effect of suvorexant on sleep physiology as assessed by polysomnography (PSG), ac...

Zolpidem is a nonbenzodiazepine GABAa receptor agonist drug that acts as a hypnotic. To accomplish this, the investigators will use a randomized double-blind placebo-controlled crossover 8-week study design to examine the effect of zolpidem on sleep physiology as assessed by polysomnography (PSG), actigraphy, circadian rhythm, and clinical measures.
