Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Genders Eligible for Study
Description
Inclusion Criteria:
- Age ≥ 16 at the time of signing the informed consent form
Patients with a diagnosis of any of the below:
- AML (CR1 or CR2) according to World Health Organization (WHO) classification;
- Secondary AML (defined as previous history of MDS, antecedent hematological disease or chemotherapy exposure; CR1 or CR2); or
- Advanced or high risk MDS with an IPSS-R of ≥3.5 (intermediate 3.5 or higher) including intermediate or high risk chronic myelomonocytic leukaemia (CMML) (e.g. CPSS int-2 or high risk) (as per IPSS-R)
undergoing allo-SCT using myeloablative conditioning (MAC) or reduced-intensity conditioning (RIC) preparative regimens, and with either peripheral blood or bone marrow as the source of hematopoietic stem cells.
At the time of allo-SCT
- No prior allo-SCT; and
- No more than 1 antigen mismatch at HLA-A, -B, -C, -DRB1 or -DQB1 locus for either related or unrelated donor; and
- No haplotype or cord blood donor; and
- Bone marrow blast <5% for AML and <10% for MDS patients
- Able to commence therapy between 42 to 84 days following allo-SCT
Post-transplant bone marrow
- AML patients - blast count ≤ 5% confirmed within 28 days prior to starting study therapy
- MDS patients - confirmation of CR post-transplant with blast count ≤ 5% in bone marrow
Adequate neutrophil and platelet engraftment within 14 days prior to starting study therapy defined as:
- Absolute neutrophil count (ANC) ≥ 1.0 x 10^9/L on two consecutive testing without daily use of myeloid growth factor; and
- Platelet ≥ 50 x 10^9/L on two consecutive testing without platelet transfusion within 1 week
Adequate organ function:
- Serum aspartate aminotransferase (AST) and alanine transaminase (ALT) < 4 x upper limit of normal (ULN)
- Serum bilirubin < 2 x ULN. Higher levels are acceptable if these can be attributed to active red blood cell (RBC) precursor destruction within the bone marrow (i.e., ineffective erythropoiesis) or Gilbert's syndrome
- Serum creatinine < 2 x ULN
- Adequate coagulation (Prothrombin time (PT) ≤ 15 seconds and partial thromboplastin time (PTT) ≤ 40 seconds)
- Eastern Cooperative Oncology Group (ECOG) performance status of ≤ 2
- Patients with adequately controlled GVHD (defined as GVHD grade <II with concurrent use of corticosteroids equivalent of prednisone at a dose ≤ 0.5 mg/kg) can be included
Females of childbearing potential (FCBP) may participate, providing they meet the following conditions:
- Agree to use at least two effective contraceptive methods (oral, injectable, or implantable hormonal contraceptive; tubal ligation; intra-uterine device; barrier contraceptive with spermicide; or vasectomised partner) or practice true abstinence throughout the study, and for 6 months following the last dose of study therapy and
- Have a negative serum pregnancy test (sensitivity of at least 25 mIU/mL) at screening; and
- Have a negative serum or urine (investigator's discretion) pregnancy test (sensitivity of at least 25 mIU/mL) within 72 hours prior to starting study therapy. This applies even if the subject practices complete abstinence from heterosexual contact.
- Male patients with a female partner of childbearing potential must agree to the use of at least two physician-approved contraceptive methods throughout the course of the study and should avoid fathering a child during the course of the study and for 3 months following the last dose study therapy
- Understand and voluntarily sign an informed consent from prior to any study related assessments or procedures being conducted
- Able to adhere to the study visit schedule (i.e., clinic visits at the study sites are mandatory, unless noted otherwise for study visits) and other protocol requirements
Exclusion Criteria:
Use of any of the following after transplantation and prior to starting study therapy:
- Any chemotherapy used for adjuvant therapy
- Unlicensed investigational agents/therapies used within 28 days prior to starting study therapy
- Azacitidine, decitabine or other hypomethylating agent (HMA)
- Lenalidomide, thalidomide and pomalidomide used within 28 days prior to starting study therapy
- Subjects who have undergone a haploidentical or cord blood transplant
- Active GVHD grade II or higher (acute GVHD Clinical Staging and Grading)
- Concurrent use of corticosteroids equivalent of prednisone at a dose > 0.5 mg/kg
- Known active viral infection with Human Immunodeficiency Virus (HIV), Hepatitis B Virus (HBV) or Hepatitis C Virus (HCV)
- Active uncontrolled systemic fungal, bacterial, or viral infection (defined as ongoing signs/symptoms related to the infection without improvement despite appropriate antibiotics, antiviral therapy, and/or other treatment)
- History of inflammatory bowel disease (e.g., Crohn's disease, ulcerative colitis), celiac disease (i.e., sprue), prior gastrectomy or upper bowel removal, or any other GI disorder or defect that may interfere with the absorption, distribution, metabolism or excretion of the investigational medicinal products (IMPs) and/or predispose the subject to an increased risk of gastrointestinal toxicity prior to allo-SCT
- Idiopathic thrombocytopenic purpura (ITP), disseminated intravascular coagulation, haemolytic uremic syndrome, thrombotic thrombocytopenic purpura (TTP)
- History of prior malignancies, except: lobular breast carcinoma in situ, fully resected basal cell or squamous cell carcinoma of skin or treated cervical carcinoma in situ, Incidental histologic finding of prostate cancer (T1a or T1b using the tumor, node, metastasis (TNM) clinical staging system), previous MDS, CMML, myeloproliferative neoplasms (MPN) resulting in secondary AML. Cancer treated with curative intent ≥ 5 years previously will be allowed. Cancer treated with curative intent < 5 years previously will not be allowed.
Significant active cardiac disease within the previous 6 months, including:
- New York Heart Association (NYHA) class III or IV congestive heart failure
- Unstable angina or angina requiring surgical or medical intervention; and/or
- Myocardial infarction
- Known or suspected hypersensitivity to azacitidine or mannitol
- Pregnant or lactating females
- Any significant medical condition, laboratory abnormality, or psychiatric illness that would prevent the patient from participating in the study.
- Any condition including the presence of laboratory abnormalities, which places the patient at unacceptable risk if he/she were to participate in the study
- Any condition that confounds the ability to interpret data from the study
