E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
A/ Age ≥ 18
B/ CMML diagnosis according to WHO criteria
- Stable excess in blood monocytes, > 1 G/L and accounting for > 10% WBC
- Lack of bcr-abl rearrangement (or Philadelphia chromosome). There should be at least one BCR-ABL test (cytogenetics or molecular biology) dating from the date of CMML diagnosis up to date of screening.
- Bone marrow blast cells < 20%
- Dysplasia of at least one lineage or clonality marker or blood monocytosis during more than 3 months w/o other explanation
- Blood and marrow smears will be reviewed at each country’s level, but morphologist meetings at the 3 country level are planned for better harmonization and review of difficult cases
C/ WBC ≥ 13 G/L
Measured on two successive CBC at least two weeks apart, outside of a context of infection and before initiation of treatment by Hydroxyurea.
D/ Either D1 or D2
D1/ At least two of the following criteria, reviewed at each country’s level: (modified from Wattel et al. Blood 1996)
- Marrow blasts >= 5 %
- Clonal cytogenetic abnormality (other than t(5;12) (q33; p13) and isolated loss of Y chromosome )
- Anemia (Hb < 10 g/dL)
- ANC > 16 G/l (in absence of infection)
- Thrombocytopenia (platelet count < 100 G/L)
- Splenomegaly > 5 cm below costal margin (spleen size should also be measured by an imaging technique)
Or:
D2/ Extramedullary involvement: Including documented cutaneous, pleural or pericardial effusion.
E/ No prior treatment (except supportive care, or ESA, or short term (< 6 weeks before the screening date) HY in patients presenting with high WBC counts). The 6-week period for HY treatment can be prolonged to no more than 8 weeks in patients to allow complete exclusion of donor availability in patients fit for allogeneic stem cell transplantation lacking sibling donors.
F/ Performance status 0-2 on the Eastern Cooperative Oncology Group (ECOG) Scale.
G/ Adequate organ function including the following
- Hepatic : total bilirubin < 1.5 times upper limit of normal (ULN) (except moderate unconjugated hyperbilirubinemia due to intra medullary hemolysis or Gilbert syndrome) , alanine transaminase (ALT) and aspartate transaminase (AST) < 3xULN
- Renal : serum creatinine < 2 x ULN
H/ Signed Informed consent
I/ Negative pregnancy and adequate contraception (including in male patients wishing to father) if relevant.
Female subjects of chilbearing potential* must:
* A female patient or a female partner of a male patient is considered to have childbearing potential unless she meets at least one of the following criteria:
- Age ≥ 50 years and naturally amenorrhoeic for ≥ 1 year (amenorrhoea following cancer therapy does not rule out childbearing potential)
- Premature ovarian failure confirmed by a specialist gynaecologist
- Previous bilateral salpingo-oophorectomy, or hysterectomy
- XY genotype, Turner syndrome, uterine agenesis.
Agree to have a medically supervised pregnancy test on the day of the study visit or in the 3 days prior to the study visit once the subject has been on effective contraception for at least 4 weeks. This requirement also applies to women of childbearing potential who practice complete and continued abstinence. The test should ensure the subject is not pregnant when she starts treatment.
Agree to have a medically supervised pregnancy test every 4 weeks including 4 weeks after the end of study treatment, except in the case of confirmed tubal sterilization. These pregnancy tests should be performed on the day of the study visit or in the 3 days prior to the study visit. This requirement also applies to women of childbearing potential who practice complete and continued abstinence
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 even if she has amenorrhoea. This applies unless the subject commits to absolute and continuous abstinence confirmed on a monthly basis, to avoid pregnancy for the duration of study.
The following can be considered to be examples of suitable methods of contraception for female patients: implant, levonorgestrel-releasing intrauterine system (IUS), medroxyprogesterone acetate depot, tubal sterilisation, sexual intercourse with a vasectomised male partner only (vasectomy must be confirmed by two negative semen analyses), ovulation inhibitory progesterone-only pills (i.e., desogestrel).
If not established on effective contraception, the female subject must be referred to an appropriately trained health care professional for contraceptive advice in order that contraception can be initiated.

o In case of RBC transfusion independence prior to randomization: reduction in Hgb by 2 g/dL or RBC transfusion dependence ≥ 4 RBC units / 8 weeks or
- In case of RBC transfusion dependence prior to randomization: increase in RBC transfusion dependence by ≥ 4 RBC units / 8 weeks compared to baseline.
