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

A Study of Vedolizumab With and Without Upadacitinib in Adults With Crohn's Disease
Recruiting
The main aim of this study is to learn whether vedolizumab and upadacitinib given together (also called dual targeted therapy or DTT) reduces bowel inflammation and ulcers in the bowel compared to vedolizumab only (also called monotherapy) in adults with moderately or severely active Crohn's Disease (CD) after 12 weeks of treatment. Other aims are to learn how safe and effective DTT is compared to monotherapy for these participants. All participants will receive DTT (either vedolizumab and upad... Read More

Durvalumab With Gemcitabine and Cisplatin for the Treatment of High-Risk Resectable Liver Cancer Before Surgery
Recruiting
This phase II trial tests how well giving durvalumab with standard chemotherapy, gemcitabine and cisplatin, before surgery works in treating patients with high risk liver cancer (cholangiocarcinoma) that can be removed by surgery (resectable). Durvalumab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as gemcitabine and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stop... Read More
