Prospective, Multicentric, Phase II Randomized Controlled Trial on Two Parallel Groups Comparing the Efficacy of Two Immunosuppressive Drugs (Methotrexate, Cyclophosphamide) in Large Granular Lymphocytes Leukemia (LGL)
Large Granular Lymphocytes Leukemia
About this trial
This is an interventional treatment trial for Large Granular Lymphocytes Leukemia focused on measuring large granular lymphocytes leukemia, immunosuppressive drugs, methotrexate, cyclophosphamide, efficiency, phase II randomized controlled trial
Eligibility Criteria
Inclusion Criteria:
- Common criteria of LGL leukemia: the diagnosis is based on a chronic LGL peripheral blood expansion (>0.5x109/L), usually lasting more than 6 months
Specific criteria for T-LGL leukemia or NK-LGL lymphocytosis or chronic NK-LGL leukemia:
- Specific criteria for T-LGL leukemia:
- Expression of LGL surface markers compatible with an activated T-cell (commonly alpha-beta+/CD3+/CD8+/CD57+ and/or CD16+) phenotype or gamma-delta+ T cells;
Clonal rearrangement of TCRγ gene using PCR or specific and clonal Vβ expression using FCM.
- Specific criteria for NK-LGL lymphocytosis or chronic NK LGL leukemia:
- Expression of LGL surface markers compatible with a NK cell (commonly CD3-/CD8+/CD16+ and/or CD16+/CD56+) phenotype;
- CD56+ or CD16+ NK cells greater than 0.75x109/L;
- The term of chronic NK-LGL lymphocytosis is used for patients with chronic illness (NB: patients with massive tissue LGL infiltration of the spleen, liver and bone marrow and presenting aggressive clinical behavior are considered as having aggressive NK-LGL leukemia and should not be included).
- Age above 18 years
- ECOG performance status of 0-2
- Life expectancy of at least 1 year
- Lack of previous treatment (except with G-CSF or transfusions)
At least one indication of treatment:
- Isolated severe neutropenia (ANC <0.5x109/L) or neutropenia (ANC <1.5x109/L) with two or more infections requiring antibiotics;
- Anemia (whatever the underlying mechanism: pure red cell aplasia or marrow infiltration) requiring transfusions greater than 2 units for two months prior to inclusion, or symptomatic anemia (hemoglobin <10g/dl) with impairment of the quality of life;
- Associated complications such as systemic diseases or auto-immune diseases (i.e. recurrent uveitis, cutaneous vasculitis, autoimmune hemolytic anemia, idiopathic thrombocytopenic purpura, rheumatoid arthritis resistant to steroids and/or immunomodulator agents (colchicin, disulone, hydrochloroquine)) and justifying a treatment with methotrexate or cyclophosphamide
- Written informed consent
Exclusion Criteria:
- Inability to understand or to follow study procedures
- Prior or concurrent malignancy within the past 5 years except inactive nonmelanomatous skin cancer or carcinoma in situ of the cervix
- Other serious medical illnesses, such as hepatic, renal, cardiac, pulmonary, neurologic, or metabolic disease that would preclude the patient's ability to tolerate methotrexate, cyclophosphamide, or ciclosporine A
- Reactive LGL lymphocytosis (i.e. after viral infection)
- ALAT/ASAT or alkalin phosphatases >3 times normal values
- Creatinine clairance <50 ml/min
- Serologic evidence of HIV, hepatitis C or hepatitis B infection
- Non effective contraception
- Positive pregnancy test
- Nursing woman

METHOTREXATE
CYCLOPHOSPHAMIDE
In step 1, 55 patients will receive methotrexate 10mg / m² orally once a week, (at split doses of 5 mg/m2 in the morning and 5 mg/m2 at night), that is to say 2 tablets of 2.5 mg at each take In step 2, responders at Month 4 (CR or PR) will be treated during 8 additional months with methotrexate at the same dosage. Non responders at Month 4 will be randomized and treated either by: Cyclophosphamide delivered at 100 mg orally once daily, that is to say 2 tablets of 50 mg at each take between Month 5 and Month 8, decreased to 50 mg orally once daily beyond Month 8 for responders at Month 8; Ciclosporine A delivered at 3 mg/kg per day (at split doses of 1.5 mg/kg in the morning and 1.5 mg/kg at night) orally administered.
