Treatment Clinical Trials for Hairy Cell Leukemia
Clinical trials are research studies that involve people. The clinical trials on this list are for hairy cell leukemia treatment. All trials on the list are supported by NCI.
NCI’s basic information about clinical trials explains the types and phases of trials and how they are carried out. Clinical trials look at new ways to prevent, detect, or treat disease. You may want to think about taking part in a clinical trial. Talk to your doctor for help in deciding if one is right for you.
Ibrutinib in Treating Patients with Relapsed Hairy Cell Leukemia
This phase II trial studies how well ibrutinib works in treating patients with hairy cell leukemia that has returned after a period of improvement. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Vemurafenib and Obinutuzumab in Treating Patients with Previously Untreated Classical Hairy Cell Leukemia
This phase II trial studies how well vemurafenib and obinutuzumab work in treating patients with previously untreated classical hairy cell leukemia. Vemurafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as obinutuzumab, may help the body’s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving vemurafenib and obinutuzumab may work better in treating patients with previously untreated hairy cell leukemia.

Cladribine With Simultaneous or Delayed Rituximab to Treat Hairy Cell Leukemia
Background: Hairy cell leukemia (HCL) is highly responsive to but not curable by cladribine (CdA). HCL responds to rituximab, which is not yet standard therapy for HCL. Patients with the CD25-negative variant (HCLv) respond poorly to initial cladribine but do respond to rituximab in anecdotal reports. Deoxycytidine kinase phosphorylates cladribine to CdATP, which incorporates into DNA, leading to DNA strand breaks and inhibition of DNA synthesis. Rituximab is an anti-CD20 monoclonal antibody which induces apoptosis and either complement or antibody dependent cytotoxicity (ADCC or CDC). Patients in complete remission (CR) to cladribine have minimal residual disease (MRD) by immunohistochemistry of the bone marrow biopsy (BMBx IHC), a risk for early relapse. Tests for HCL MRD in blood or marrow include flow cytometry (FACS) or PCR using consensus primers. The most sensitive HCL MRD test is real-time quantitative PCR using sequence-specific primers (RQ-PCR). In studies with limited follow-up, MRD detected by tests other than RQ-PCR can be eliminated by rituximab after cladribine in greater than 90 percent of patients, but MRD rates after cladribine alone are unknown. Simultaneous cladribine and rituximab might be superior or inferior to delaying rituximab until detection of MRD. Only 4 HCL-specific trials are listed on Cancer.gov: a phase II trial of cladribine followed 4 weeks later by 8 weekly doses of rituximab, and phase I-II trials of recombinant immunotoxins targeting CD22 (BL22, HA22) and CD25 (LMB-2). Objectives: Primary: To determine if HCL MRD differs at 6 months after cladribine with or without rituximab administered concurrently with cladribine. Secondary: - To compare cladribine plus rituximab vs cladribine alone in terms of 1) initial MRD-free survival and disease-free survival, and 2) response to delayed rituximab for relapse, to determine if early rituximab compromises later response. - To determine if MRD levels and tumor markers (soluble CD25 and CD22) after cladribine and / or rituximab correlate with response and clinical endpoints. - To determine, using MRD and tumor marker data, when BMBx can be avoided. - To compare response and MRD after the 1st and 2nd courses of cladribine. - To evaluate the effects of cladribine and rituximab on normal T- and B-cells. - To enhance the study of HCL biology by cloning, sequencing and characterizing monoclonal immunoglobulin rearrangements. Eligibility: HCL with 0-1 prior courses of cladribine and treatment indicated. Design: Cladribine 0.15 mg / Kg / day times 5 doses each by 2hr i.v. infusion (days 1-5) Rituximab 375 mg / m2 / week times 8 weeks, randomized half to begin day 1, then repeat for all patients with blood-MRD relapse at least 6 months after cladribine. Also may repeat for those with blood-MRD relapse at least 6 months after delayed rituximab. MRD tests used for the primary objective will be limited to BMBx IHC, blood FACS or blood consensus PCR, all CLIA certified. Blood MRD relapse is defined as FACS positivity or low blood counts (ANC less than 1500 / microl, Plt less than 100,000 / microl, or Hgb less than 11). Stratification: 68 patients with 0 and 62 with 1 prior course of cladribine. Statistics: 80% power to discriminate rates of MRD of 5 vs 25%, or 10 vs 35% Non-randomized arm: 20 with HCLv will begin rituximab with cladribine. Accrual Ceiling: 152 patients (130 HCL, 2 extra HCL if needed, and 20 HCLv.) ...

Genetic Analysis in Determining Individualized Treatment for Patients with Recurrent or Refractory Blood Cancers
This trial uses genetic analysis to determine a personalized treatment plan for patients with blood cancers that have come back or do not respond to treatment. Personalized cancer therapy is the practice of making decisions about what kind of treatment patients should receive based on the genetic makeup of their tumors. Genes carry the instructions to make proteins, and certain gene changes can cause cells to evade normal growth controls and become cancer. Genes in cancer cells have changed from those in normal cells. Researchers believe that abnormal genes in tumors may affect how individuals respond to cancer treatments. Studying the information collected from medical records about the tests and treatments patients have received may help doctors describe whether or not patients respond better when they receive treatment based on the genetic makeup of their tumor.

Venetoclax, Carmustine, Etoposide, Cytarabine, and Melphalan before Stem Cell Transplant in Treating Patients with Relapsed or Refractory Non-Hodgkin Lymphoma
This phase I / II trial studies the side effects and best dose of venetoclax when given together with carmustine, etoposide, cytarabine, and melphalan before stem cell transplant in treating patients with non-Hodgkin lymphoma that has come back or does not respond to treatment. Drugs used in chemotherapy, such as venetoclax, carmustine, etoposide, cytarabine, and melphalan, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy before a stem cell transplant helps kill any cancer cells that are in the body and helps make room in the patient’s bone marrow for new blood-forming cells (stem cells) to grow.

Randomized Phase II Trial of Rituximab With Either Pentostatin or Bendamustine for Multiply Relapsed or Refractory Hairy Cell Leukemia
Background: - Researchers are attempting to develop new treatments for hairy cell leukemia (HCL) that has not responded well to or has recurred after standard HCL therapies. One nonstandard treatment for HCL is rituximab, an antibody that binds to the cancer cells and helps the immune system destroy them. By combining rituximab with other anti-cancer drugs, researchers hope to determine whether the combined drugs are successful in treating HCL. - Pentostatin and bendamustine are two anti-cancer drugs that have been used to treat different kinds of blood and immune system cancers. Bendamustine is approved to treat other kinds of leukemia and lymphoma, but it has not been used to treat HCL. Pentostatin has been used for more than 20 years to treat HCL, but it has not been combined with rituximab in official clinical trials. Objectives: - To determine whether rituximab with either pentostatin or bendamustine is a more effective treatment for HCL than rituximab alone. - To determine whether pentostatin or bendamustine is a more effective treatment for HCL when combined with rituximab. Eligibility: - Individuals at least 18 years of age who have been diagnosed with hairy cell leukemia that has not responded well to or has relapsed after standard HCL therapies. Design: - The study will last for four treatment cycles of 28 days each. - Prior to the study, participants will be screened with a full medical history and physical exam, bone marrow biopsy (if one has not been performed in the last 6 months), computed tomography (CT) or ultrasound scan, tumor measurements, and other tests as required by the researchers. Participants will provide blood and urine samples at this time as well. - Rituximab with bendamustine: Participants will receive rituximab on Days 1 and 15 of each cycle and bendamustine on Days 1 and 2 of each cycle, for a total of four cycles. - Rituximab with pentostatin: Participants will receive rituximab on Days 1 and 15 of each cycle and pentostatin on rituximab on Days 1 and 15 of each cycle, for a total of four cycles. - Participants will have regular tests during the treatment cycles, including bone marrow biopsies and CT or ultrasound scans. Participants will also provide regular blood and urine samples to assess the results of treatment.

Title: Moxetumomab Pasudotox-tdfk (Lumoxiti ) and Rituximab (Rituxan ) for Relapsed Hairy Cell Leukemia
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 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 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. Both 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 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 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.
