Detailed Summary

Background: Hairy cell leukemia (HCL) is a rare, slow-growing blood cancer in which the bone marrow makes too many of certain white blood cells. The antibody Rituximab/Ruxience binds to a protein in cancerous white blood cells and is often used to treat HCL. Researchers want to see if combining it with the drug Moxetumomab pasudotox-tdfk (also called Lumoxiti) can fight HCL better. Objective: To test the safety of Moxetumomab pasudotox taken with Rituximab/Ruxience for people with HCL or HCL variant. Eligibility: People age 18 years and older with HCL or HCL variant that has not responded to standard therapy Design: Participants will be screened with: Medical history Physical exam Blood, heart, and urine tests Test of blood oxygen levels Review of bone marrow. This can be from previous test results or a new sample. Scans Exercise test Participants will get the study drugs in up to 8 cycles. A cycle will last about 28 days. The study drugs will be given through a plastic tube in a vein. In the first week of cycle 1, participants will have: 1 visit to get Rituximab or Ruxience for 7.5 hours 3 visits to get Lumoxiti for 30 minutes per infusion In the first week of cycles 2-8, participants will have: 1. visit to get Rituximab/Ruxience for 2-4 hours and Lumoxiti for 30 minutes 2. visits to get Lumoxiti for 30 minutes per infusion Participants will be asked to drink lots of water and take aspirin during the cycles. They will get drugs to minimize allergic reactions. Participants will repeat screening tests at visits throughout the cycles and 1 follow-up visit. They may have an eye exam. ...
