The researchers are doing this study to compare the safety of vemurafenib in combination with obinutuzumab to the standard of approach of cladribine in combination with rituximab. The researchers will look at which treatment causes fewer or milder side effects. Researchers think vemurafenib and obinutuzumab (non-chemotherapy drugs) may cause fewer side effects compared with the usual approach of chemotherapy drugs. They will also compare the two approaches to see which approach is more effective at eliminating cancer cells.

Background: Hairy cell leukemia (HCL) does not usually respond to chemotherapy. Most people with HCL have a BRAF gene mutation. This can increase the growth of cancer cells. Vemurafenib has been tested to treat these people. However, researchers think a combination of drugs might work better. Objective: To test if treatment with a combination of encorafenib and binimetinib in BRAF mutant HCL is more effective than treatment with vemurafenib. Eligibility: People ages 18 and older with BRAF mutant HCL that did not respond to or came back after treatment Design: Participants will be screened with: Medical history Physical exam Bone marrow biopsy: A needle will be injected through the participant s skin and into a bone to remove liquid. Blood and urine tests Heart and lung function tests CT or MRI scan: Participants will lie in a machine that takes pictures of the body. They may have a contrast agent injected into a vein. Eye exam Participants will take the study drugs by mouth in 28-day cycles. They will take encorafenib daily. They will take binimetinib twice daily. They will keep a pill diary. Participants will take their temperature daily. Participants will have at least 1 visit before each cycle. Visits will include repeats of some screening tests. They will also include abdominal ultrasounds, exercise stress tests, and skin evaluations. Participants may continue treatment as long as their disease does not get worse and they do not have bad side effects. About a month after their last dose of treatment, participants will have a follow-up visit. Then they will have annual follow-ups....

Background: Most people with hairy cell leukemia have a BRAF gene mutation. They can be treated with BRAF inhibitors, drugs that target this mutation. For people who do not have this mutation, BRAF inhibitors are not a treatment option. We found that in hairy cell leukemia, when BRAF is not mutated, the MEK gene frequently is. Binimetinib is a MEK inhibitor which targets MEK. It is important to determine if this drug can be a good treatment option in those who cannot benefit treatment with BRAF inhibitors. Objective: To see if binimetinib is an effective treatment for hairy cell leukemia that does not have a BRAF mutation. Eligibility: People ages 18 and older with hairy cell leukemia without a mutation in the BRAF gene and whose disease either did not respond to treatment or came back after treatment Design: Participants will be screened with: * Medical history * Physical exam * Blood and urine tests * Lung and heart tests * Eye exam * Bone marrow biopsy: A needle will be injected through the participant s skin into the bone to remove a sample of marrow. * CT or MRI scan: Participants will lie in a machine that takes pictures of the body. They might receive a contrast agent by vein. Before they start treatment, participants will have an abdominal ultrasound, pulmonary function tests, and exercise stress tests. Participants will take binimetinib by mouth twice daily in 28-day cycles. They will keep a medication diary. Participants will have at least one visit before every cycle. Visits will include repeats of some screening tests. Participants may continue treatment as long as their disease does not get worse and they do not have bad side effects. About a month after their last dose of treatment, participants will have a follow-up visit. They will then have visits once a year. ...

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.

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.)

Background: CAR (Chimeric Antigen Receptor) T cell therapy is a type of cancer treatment in which a person s T cells (a type of immune cell) are changed in a laboratory to recognize and attack cancer cells. Researchers want to see if this treatment can help people with hairy cell leukemia (HCL). Objective: To test whether it is safe to give anti-CD22 CAR T cells to people with HCL. Eligibility: Adults ages 18 and older with HCL (classic or variant type) who have already had, are unable to receive, or have refused other standard treatments for their cancer. Design: Participants will be screened with the following: Medical history Physical exam Blood and urine tests Biopsy sample Electrocardiogram Echocardiogram Lung function tests Imaging scans Some screening tests will be repeated during the study. Participants may need to have a catheter placed in a large vein. Participants will have magnetic resonance imaging of the brain. Participants will have a neurologic evaluation and fill out questionnaires. Participants will have leukapheresis. Blood will be removed from the participant. A machine will divide whole blood into red cells, plasma, and lymphocytes. The lymphocytes will be collected. The remaining blood will be returned to the participant. Participants will get infusions of chemotherapy drugs. Participants will get an infusion of the anti-CD22 CAR T cells. They will stay at the hospital for 14 days. Then they will have visits twice a week for 1 month. After treatment, participants will be followed closely for 6 months, and then less frequently for at least 5 years. Then they will have long-term follow-up for 15 years.

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. ...

This is a multi-center, open label, single arm, phase II trial of the oral BRAF inhibitor, vemurafenib, plus obinutuzumab in patients with previously untreated HCL. A Simon mini-max two-stage design will be employed to assess the efficacy of the combination treatment of vemurafenib and obinutuzumab. In the first stage of the protocol, 9 patients will be treated. If fewer than 6 CRs are seen among the first 9 patients, the study will be closed for lack of efficacy. If at least 7 patients respond to the treatment, then an additional 19 patients will be accrued to the second stage, for a total of 28 patients. Eligible patients will receive vemurafenib at a dose of 960mg orally twice daily (b.i.d.) continuously in cycles of 4 weeks (28 days) for a total of 4 cycles. Obinutuzumab will be administered concomitantly with vemurafenib starting at cycle 2 of treatment in cycles of 4 weeks. Obinutuzumab infusions will be administered at 1000mg per day on days 1, 8 and 15 during the cycle 2 and 1000mg per day every 4 weeks during the cycle 3 and 4 of treatment. After the completion of the treatment (i.e. after 4 cycles), a bone marrow aspirate and biopsy will be performed for assessment of response and evaluation of minimal residual disease (MRD). In case of certain defined toxicities, dose reductions of vemurafenib by 50% (480mg b.i.d.) or interruptions of up to 15 days are permitted. If additional dose reduction is required, vemurafenib may be reduced to 240mg oral b.i.d.

The current standard-of-care for Hairy Cell Leukemia involves chemotherapy, with agents such as cladribine or pentostatin. Chemotherapy is associated with infection, low blood counts and predisposition to future cancers. This study tests a new yet previously validated drug combination for the treatment of hairy cell leukemia. The treatment involves 8 weeks of treatment with an oral drug called vemurafenib and 8 doses of an intravenous medication called rituximab. The goal of this study is to see whether this treatment is better tolerated and more effective than the currently used treatment in this disease. In addition, this study uses a lower dose of vemurafenib than previous studies have used, with the goal of minimizing side effects from this medication.

This phase I trial studies the side effects and best dose of genetically modified T-cells following peripheral blood stem cell transplant in treating patients with recurrent or high-risk non-Hodgkin lymphoma. Giving chemotherapy before a stem cell transplant helps stop the growth of cancer cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Removing the T cells from the donor cells before transplant may stop this from happening. Giving an infusion of the donor's T cells (donor lymphocyte infusion) later may help the patient's immune system see any remaining cancer cells as not belonging in the patient's body and destroy them (called graft-versus-tumor effect)

This phase I/Ib trial investigates the side effects of CC-486 and how well it works in combination with lenalidomide and obinutuzumab in treating patients with CD20 positive B-cell lymphoma that has come back (recurrent) or has not responded to treatment (refractory). Chemotherapy drugs, such as CC-486, 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. Lenalidomide is a drug that alters the immune system and may also interfere with the development of tiny blood vessels that help support tumor growth. Therefore, in theory, it may reduce or prevent the growth of cancer cells. Obinutuzumab is a type of antibody therapy that targets and attaches to the CD20 proteins found on follicular lymphoma cells as well as some healthy blood cells. Once attached to the CD20 protein the obinutuzumab is thought to work in different ways, including by helping the immune system destroy the cancer cells and by destroying the cancer cells directly. Giving CC-486 with lenalidomide and obinutuzumab may improve response rates, quality, and duration, and minimize adverse events in patients with B-cell lymphoma.

Frequently Asked Questions

How much do Hairy Cell Leukemia clinical trials pay?

Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

How do Hairy Cell Leukemia clinical trials work?

After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Hairy Cell Leukemia trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Hairy Cell Leukemia is 12 months.

How do I participate in a study as a "healthy volunteer"?

Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

What does the "phase" of a clinical trial mean?

The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

Do I need to be insured to participate in a Hairy Cell Leukemia medical study ?

Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.

What are the newest Hairy Cell Leukemia clinical trials ?

Most recently, we added Venetoclax for Relapsed Hairy Cell Leukemia, Vemurafenib + Obinutuzumab vs Cladribine + Rituximab for Hairy Cell Leukemia and CAR T Cells for Lymphoma to the Power online platform.
