Loncastuximab Tesirine and Mosunetuzumab for the Treatment of Relapsed or Refractory Diffuse Large B-Cell Lymphoma
Recruiting
This phase II trial studies the safety and how well of loncastuximab tesirine when given together with mosunetuzumab works in treating patients with diffuse large B-cell lymphoma that has come back (relapsed) or does not respond to treatment (refractory). Loncastuximab tesirine is a monoclonal antibody, loncastuximab, linked to a toxic agent called tesirine. Loncastuximab attaches to anti-CD19 cancer cells in a targeted way and delivers tesirine to kill them. Mosunetuzumab is a monoclonal antibo... Read More

Evaluating tDCS Brain-stimulation in Depression Using MRI
Recruiting
Patients, physicians, and those who fund depression research are keenly interested in depression treatments that do not involve taking medications. One promising candidate treatment is transcranial direct current stimulation (tDCS), a low-cost technique that involves placing electrodes on specific scalp locations and using a 9-volt battery to cause a small amount of electricity to pass through parts of the brain. Depending on the direction of electrical flow, tDCS can make brain cells (neurons)... Read More

Testing the Use of the Combination of Selumetinib and Olaparib or Selumetinib Alone Targeted Treatment for RAS Pathway Mutant Recurrent or Persistent Ovarian and Endometrial Cancers, A ComboMATCH Treatment Trial
Recruiting
This phase II ComboMATCH treatment trial compares selumetinib plus olaparib to selumetinib alone in women with endometrial or ovarian (fallopian tube and primary peritoneal) cancer that has come back (recurrent) or that remains despite treatment (persistent) and harbors a mutation in the RAS pathway. Selumetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
