a study of azacitidine in myelodysplastic syndrome (mds) associated to systemic auto-immune and inflammatory disorders

Conditions: MDS; Systemic Autoimmune Diseases

Summary: this study is a phase ii of effcicacy and tolerance of azacitidine in patients with myelodysplatic syndrome and steroid dependent or resistent systemic auto-immune and inflammatory disorders

this trial will be a prospective french nationwide study analyzing the effect of treatment with azacitidine in patients with mds-associated said with steroid dependence and/or resistance, and its correlation with possible changes in immunological parameters

Eligibility criteria:
inclusion criteria: * must understand and voluntarily sign the informed consent form * age 18 years at the time of signing the informed consent form * must be able to adhere to the study visit schedule and other protocol requirements * mds or cmml or aml with 20-30% marrow blasts using 2008 who classification, with any of the following characteristics : 1. ipss intermediate 2 or high, including aml with 20 to 30% marrow blasts and cmml with wbc\ 10%, 2. ipss low or int 1 in need of treatment (transfusion dependent anemia resistant to esas and/or platelets below 30 g/l or below 50 g/l with bleeding or platelet transfusion requirement, and/or anc \< 0.5 g/l with infectious complications) 3. documented (by cytogenetic or molecular analysis) mds /cmml not meeting those criteria, but with at least one significant cytopenia (hb \<10 g/dl, platelets \<50g/l, anc \<1 g/l). in this situation, the underlying said should be severe and have resisted to a second line treatment (following steroids), if such treatment can be proposed for this particular said. those cases should be discussed prior to inclusion with the trial sponsors complications) * said-associated with mds defined according to usual international criteria for each said (ie acr criteria for systemic lupus, chapel hill classification for systemic vasculitis, etc...) * steroid dependence and/or resistance of said (steroid dependence being defined as the impossibility to decrease steroids during at least 2 months below 15 mg/day; steroid resistance as no response of said to at least 1 mg/kg/day of prednisone equivalent during one month) * ineligibility for allogeneic stem cell transplantation during the following 12 months * wash-out at least 6 months since a previous treatement with lenalidomide * no previous use of hypomethylating agents * life expectancy ≥ 6 months * adequate liver function (serum transaminases ≤ 3n) * adequate renal function (creatinine clearance with mdrd formula \> 30 ml/min) * women of child-bearing potential (i.e., women who are pre-menopausal or not surgically sterile) must : * have a negative serum or urine pregnancy test within 2 weeks prior to beginning treatment on this study. lactating patients are excluded. * agree to use, and to be able to comply with, effective contraception without interruption, 4 weeks before starting study drug throughout the entire duration study drug therapy (including doses interruptions) and for 3 months after the end of the study drug therapy. * male patients must : * agree the need for the use of a condom if engaged in sexual activity with a woman of childbearing potential during the entire period of treatment, even if disruption of treatment and during 3 months after end of treatment. * agree to learn about the procedures for preservation of sperm before starting treatment. exclusion criteria: * ipss low and intermediate-1 not meeting the criteria described above * creatinine clearance with mdrd formula \< 30 ml/min * serum total bilirubin, or serum transaminases \> 3.0 x upper limit of normal (uln) (except for unconjugated hyperbilirubinemia due to gilbert's disease or secondary to mds) * known hypersensitivity to the active substance or to any of the excipients of aza * history of severe congestive heart failure, clinically unstable cardiac or pulmonary disease * previous treatment with hypomethylating agents * life-expectancy of less than six months because of another debilitating disease * uncontrolled invasive fungal infection at time of registration or active serious infection not controlled by oral or intravenous antibiotics * known positive for hiv or acute infectious hepatitis, type b or c * any serious medical condition or psychiatric illness that will prevent the subject from signing the informed consent form or will place the subject at unacceptable risk if he/she participates in the study. * active cancer or prior history of malignancy other than mds (except basal cell or squamous cell carcinoma or carcinoma in situ of the cervix or breast) unless the subject has been free of disease for ≥ 3 years * pregnant or lactating females * no affiliation to an insurance system
