About

Hematologic improvement of erythrocytes after 6 months of canakinumab treatment.

Full description

Enrollment

10 patients

Ages

18+ years old

No Healthy Volunteers

Inclusion criteria

Diagnosis of
1. Lower-risk myelodysplastic syndrome (MDS) OR
2. Myelodysplastic/myeloproliferative neoplasm (MDS/MPN) including MDS/MPN-RS-T, MDS/MPNu, aCML, or CMML (as per the World Health Organization [WHO] 2016 classification) Note: Diagnoses will be confirmed by central morphological review during screening assessment
Very low, low or intermediate risk disease MDS with up to 3.5 points according to the revised International Prognostic Scoring System (IPSS-R) classification (to be confirmed during screening assessment). For MDS/MPN < 10% bone marrow blasts at screening. For CMML low or intermediate risk according to CMML-Specific Prognostic Scoring System (CPSS Score).
Symptomatic anemia (all NTD, LTB, or HTB): has to be documented in the 16 weeksbaseline period ending on the day of inclusion. Patients should be registered only if it is expected at time of registration that
1. a valid and complete hemoglobin and transfusion history will be available at inclusion AND
2. the hemoglobin mean over the baseline period will be less than 10 g/dL OR three or more RBC-transfusions will have been given during the baseline period documenting transfusion dependence.
Documented transfusion strategy: A transfusion trigger threshold is needed which characterizes the transfusion strategy - ideally for the whole baseline period, but at least for the time from registration to the end of the study.
Relapsed / refractory / intolerant / ineligible (endogenous serum erythropoietin levels ≥ 200 U/L) to ESA treatment
Age ≥ 18 years
Written informed consent

Exclusion criteria

Patients meeting any of the following exclusion criteria are not to be enrolled in the trial.

Compliance with major study procedures

Patient does not accept bone marrow sampling during screening and treatment period.
Patient does not accept peripheral blood sampling for screening and during treatment.
Patient does not accept subcutaneous application of canakinumab every three weeks

Contraindications
Known clinically significant anemia due to iron, vitamin B12, or folate deficiencies, or autoimmune or hereditary hemolytic anemia, or gastrointestinal bleeding

a. iron deficiency must be determined by calculated transferrin saturation (iron/total iron binding capacity) ≤ 20%, or serum ferritin ≤ 15 µg/L
Prior allogeneic or autologous stem cell transplant
Known history of diagnosis of AML

Safety
Severe neutropenia defined by ANC ≤ 0.5 Gpt/l
Severe thrombocytopenia with platelets (PLT) < 30 Gpt/L
Serum creatinine > 1.5x ULN OR measured or calculated creatinine clearance < 40 ml/min (NOTE: creatinine clearance should be calculated per institutional standard. GFR can also be used)
Serum aspartate aminotransferase/serum glutamic oxaloacetic transaminase (AST/SGOT) or alanine aminotransferase/serum glutamic pyruvic transaminase (ALT/SGPT) ≥ 3.0 x upper limit of normal (ULN) - both have to be measured
Eastern Cooperative Oncology Group (ECOG) > 2
Total bilirubin ≥ 2.0 x ULN
1. higher levels are acceptable if these can be attributed to active red blood cell precursor destruction within the bone marrow (ie, ineffective erythropoiesis).
2. subjects are excluded if there is evidence of autoimmune hemolytic anemia manifested as a corrected reticulocyte count of > 2% with either a positive Coombs' test or over 50% indirect bilirubin
Active second malignancy at time of study entry
Prior history of malignancies, other than MDS, unless the subject has been free of the disease for ≥ 5 years. However, subjects with the following history/concurrent conditions are allowed:
1. Basal or squamous cell carcinoma of the skin
2. Carcinoma in situ of the cervix
3. Carcinoma in situ of the breast
4. Incidental histologic finding of prostate cancer (T1a or T1b using the tumor, nodes, metastasis [TNM] clinical staging system)
Major surgery within 8 weeks prior to screening (NOTE: Subjects must have completely recovered from any previous surgery prior to inclusion)
Myocardial infarction, uncontrolled angina, uncontrolled heart failure, or uncontrolled cardiac arrhythmia within 6 months prior to screening
Positive test result as an indicator for active or latent tuberculosis (evaluation performed per local treatment guidelines or clinical practice)
Subjects with suspected or proven immunocompromised state or infections, including:
1. Known history of testing positive for Human Immunodeficiency Virus (HIV) infections.
2. Known active or recurrent, hepatitis B and C (positive or indeterminate laboratory results).
3. Those with any other medical condition such as active infection, treated or untreated, which in the opinion of the investigator places the subject at an unacceptable risk for participation in immunomodulatory therapy.
4. Those requiring systemic or local treatment with any immune modulating agent in doses with systemic effects e.g.: Prednisone >20 mg (or equivalent) oral or intravenous daily for >14 days; Prednisone > 5 mg and ≤ 20 mg (or equivalent) daily for > 30 days; Equivalent dose of methotrexate >15 mg weekly.
5. History of severe allergic or anaphylactic reactions or hypersensitivity to recombinant proteins or excipients in the investigational product (see Investigator´s Brochure).
Excluded treatments before and during study treatment
Anticancer cytotoxic chemotherapeutic agent or treatment for at least 14 days prior to registration and during study treatment
Corticosteroids or other immunosuppressive therapies (TNF-Blocker, other IL-1 Blocking Agent, Disease-modifying anti-rheumatic drugs (DMARDs) including ciclosporin, cyclophosphamide, hydroxychloroquine, leflunomide, methotrexate, mycophenolate, sulfasalazine) for at least 14 days prior to registration and during study treatment
Treatment with ESAs, luspatercept, granulocyte colony-stimulating factor (G-CSF), granulocyte-macrophage colony-stimulating factor (GM-CSF) for at least 14 days prior to registration and during study treatment
Treatment with disease modifying agents (eg, immune-modulatory drugs [IMiDs such as lenalidomide, hypomethylating agents] or experimental agents for underlying MDS disease for at least 14 days prior to registration and during study treatment
Prior treatment with canakinumab
Live vaccination during study treatment

Special considerations for females
Pregnant or breastfeeding females
Positive pregnancy test in women of childbearing potential NOTE: Urine or serum pregnancy test should be repeated within 3 days prior to receiving study treatment. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test is required additionally
Female subjects of childbearing potential unwilling to use an adequate method of contraception for the course of the study through 90 days after the last dose of study medication NOTE: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject

Special considerations for males
Male subjects with procreative capacity not willing to use an adequate method of contraception, starting with the first dose of study therapy through 90 days after the last dose of study therapy NOTE: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject
