Clinical Trial Summary

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. ...


Description:

Background: - Hairy cell leukemia (HCL) is an indolent B-cell leukemia comprising 2% of all leukemias, or approximately 1900 new cases per year in the US. - BRAF V600E mutation is very common in classic HCL. - HCL variant (HCLv) is wild type for BRAF and is more aggressive compared to classic HCL due to its lower response and shorter duration of response to standard purine analog chemotherapy. The median survival is only ~6 years compared to >25 years for classic HCL. - CD25+ classic-appearing HCL-cells that express unmutated IGHV4-34+ immunoglobulin rearrangement, are wild-type for BRAF, and confer a poor prognosis when treated with standard purine analog chemotherapy. - While BRAF and MEK combination inhibition is making an impact in the treatment of BRAF V600E mutated HCL, this treatment is not applicable for patients with BRAF-WT HCL/HCLv. Furthermore, with poor survival outcomes in this patient population, lack of targeted therapy constitutes a clear unmet need. - Recently, several BRAF WT HCL/HCLv patients have received MEK inhibitors by compassionate use and have had lifesaving partial to complete remission, however the response has not been assessed systematically in clinical trials. - Binimetinib (also known as MEK162) is an orally bioavailable, selective and potent mitogenactivated protein (MAP) kinase kinase (MEK1 and MEK2) inhibitor, which is approved for use in combination with encorafenib for the treatment of patients with BRAF-mutant melanoma - We have described MAP2K1 (MEK) mutations which may drive the aggressive clinical behavior of BRAF WT HCL/HCLv patients, but MEK inhibition may be clinically useful even in these patients without known MAP2K1 (MEK) mutations. Objective: -To determine the overall response rate (ORR) to binimetinib, in participants with BRAF WT HCL and HCLv. Eligibility: - BRAF WT HCL or HCLv with at least 1 prior purine analog treatment - Need for treatment as evidenced by any one of the following: ANC <1 x10^3/mcL, Hgb <10g/dL, Platelet count <100 x10^3/mcL, leukemia cell count >5 x10^3/mcL, symptomatic splenomegaly, enlarging HCL mass > 2cm in short axis. ->=18 years of age - No uncontrolled infection, cardiopulmonary dysfunction, or secondary malignancy requiring treatment. - No chemotherapy, immunotherapy, investigational agent or radiotherapy within 4 weeks prior to the start of study treatment. Design: - Single arm phase 2 trial to determine ORR in participants with relapsed/refractory BRAF WT HCL and HCLv. - 2-phase minimax design will be used to rule out an unacceptable 10% in favor of an improved 25% ORR. - Initially 16 evaluable participants will be enrolled. If 2 or more achieve a major response, then accrual will continue to a total of 31 evaluable participants. - Binimetinib will be given at a dose of 45mg BID for as long as participants can continue dosing chronically without significant toxicity or a trial off therapy due to achievement of MRD negative complete remission or PR/CR in which they would like a trial off therapy. Participants may return to therapy within 2 years of stopping treatment if evidence of disease returns.

Periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of contraception. Females of childbearing potential are defined as those who are not surgically sterile (i.e., bilateral tubal ligation, bilateral oophorectomy, or complete hysterectomy) or those who are premenarchal or postmenopausal (defined as 12 months with no menses without an alternative medical cause). A highly effective method of contraception is defined as one that results in a low failure rate (i.e., less than 1% per year) when used consistently and correctly. Not all methods of contraception are highly effective. Female subjects must use a hormonal method in addition to a barrier method alone, to minimize the chance of pregnancy. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. - Non-sterilized male participants who are sexually active with a female partner of childbearing potential must agree to use methods of contraception that are highly effective or acceptable, and not donate sperm from study entry until 90 days after the last dose of binimetinib. - Ability of subject to understand and the willingness to sign a written informed consent document. - Must co-enroll in study 10-C-0066: Collection of Human Samples to Study Hairy Cell and other Leukemias, and to Develop Recombinant Immunotoxins for Cancer Treatment EXCLUSION CRITERIA: - Participants who have had chemotherapy, immunotherapy or radiotherapy within 4 weeks prior to the start of study treatment. - Prior therapy with binimetinib. - Participants who are receiving any other investigational agents or have received an investigational agent within 14 days prior to the start of study treatment. - Participants who have undergone major surgery less than or equal to 6 weeks prior to start of study treatment or who have not recovered from side effects of such procedure. - Known hypersensitivity or contraindication to any component of binimetinib or its excipients. - Inability to swallow and retain study drug. - Is pregnant or breastfeeding or expecting to conceive within the projected duration of the study treatment, starting with the screening visit . Pregnant women are excluded from this study because binimetinib has the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with binimetinib, breastfeeding should be discontinued if the mother is treated. - Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, cardiac disfunction (details as below), uncontrolled pulmonary infection, pulmonary edema or psychiatric illness/social situations that would limit compliance with study requirements. - Evidence of active Hepatitis B Virus (HBV) or Hepatitis C Virus (HCV) infection.
