A Study of Ulocuplumab And Ibrutinib in Symptomatic Patients With Mutated CXCR4 Waldenstrom's Macroglobulinemia


Brief description of study

This research study is studying Ulocuplumab combined with ibrutinib as a possible treatment for symptomatic Waldenstrom's Macroglobulinemia (WM).

Detailed Study Description

This is a Phase I/II clinical trial. A Phase I clinical trial tests the safety of an investigational drug and also tries to define the appropriate dose of the investigational drug to use for further studies. "Investigational" means that the drug is being studied.

The FDA (the U.S. Food and Drug Administration) has not approved Ulocuplumab as a treatment for any disease. Ulocuplumab is a type of protein called an antibody that attacks CXCR4, a protein that is found on B-cells like WM.

The FDA (the U.S. Food and Drug Administration) has Ibrutinib as a treatment option for this disease.

Ibrutinib has been under investigation in research studies in participants with recurrent B-cell lymphoma, chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), mantle cell lymphoma (MCL), diffuse large B-cell lymphoma (DLBCL), and prolymphocytic leukemia, and WM. In a study of ibrutinib in relapsed/refractory WM patients, response rates were high and the treatment was well tolerated. In that study participants who had a CXCR4 mutation had a lower response rate to ibrutinib than those without a mutation.

In this research study, the investigators are evaluating the safety of ulocuplumab in combination with ibrutinib participants with symptomatic WM who have a CXCR4 mutation. The investigators are also evaluating how well the ulocuplumab works in combination with ibrutinib
