Study information

Scientific title

A phase Ib study to assess the safety and tolerability of oral Ruxolitinib in combination with 5-azacitidine in patients with advanced phase myeloproliferative neoplasms (MPN), including myelodysplastic syndromes (MDS) or acute myeloid leukaemia (AML) arising from MPN.



Study hypothesis

To establish the maximum tolerated dose (MTD) and safety of ruxolitinib in combination with 5-azacitidine

Ethics approval

NRES Committee West Midlands - Edgbaston,19/01/2015, ref: 14/WM/1260

Patient information sheet

Not available in web format, please use contact details to request a patient information shee


Topic: Cancer; Subtopic: All Cancers/Misc Sites; Disease: Leukaemia (acute myeloid), Myelodysplastic syndromes


All patients registered to the interventional component will receive treatment with a minimum of 6 cycles (each cycle 28 days) of 5-azacitidine in combination with one of 5 doses of ruxolitinib (5mg bd, 10mg bd, 15mg bd, 20mg bd, 25mg bd). 5-azacitidine will be administered on days 1-5 and 8-9 of each cycle via subcutaneous injection at a dose of 75mg/m2. Ruxolitinib will be taken orally, twice daily. If patients are achieving a clinical benefit at the end of 6 cycles, they can continue treatment for as long as they are benefitting at the discretion of the Chief Investigator. Patients will be followed up for a minimum of 1 year following registration.
The observational component will receive standard care and the trial will collect information on their outcome.

Drug names

Primary outcome measures

To determine the MTD of ruxolitinib in combination with 5-azacitidine; Timepoint(s): Within 1 cycle of treatment

Secondary outcome measures

1. Best response following 3 and 6 cycles of treatment Assessment will be made according to the following criteria: Proposed criteria for response assessment in patients treated in clinical trials for MPNs in blast phase (MPN-BP): Formal recommendations from the post-MPN acute myeloid leukaemia consortium (for patients with >20% blasts at baseline)
2. International Working Group (IWG) response criteria in myelodysplasia (for patients with <20% blasts at baseline)
3. Change in the proportion of patients who require transfusion of red cells or platelets
4. Achievement of red blood cell (RBC) transfusion independence
5. Achievement of platelet transfusion independence
6. Change in palpable splenomegaly or hepatomegaly
7. Duration of Complete Response (CR) or Partial Response (PR)
8. 12 months Progression-free survival (PFS)
9. 12 months Leukaemia-free survival (LFS)
10. 12 months Overall survival (OS)
11. Duration of treatment
12. Clinical improvement in haemoglobin level
13. Clinical improvement in platelet count
14. Quality of life as measured by the MPN SAF; EQ-5D-5L and EORTC QLQ-C30 (Cycles 1, 2, 4 and 6 for interventional patients; at registration, 3 months and 6 months for observational patients)
15. To determine treatment and outcome of Advanced Phase MPN (MPN-AP) and Blast Phase MPN (MPN-BP) patients who enter the observation component.
16. Change in clonal marker (e.g. JAK2 or CALR allele burden) (to be centrally assessed)

1. Age ≥ 16 years old
2. A prior diagnosis of Essential Thrombocythaemia (ET), Polycythaemia Vera (PV) or Myelofibrosis (MF) with one of the following:
2.1. Blasts in blood or marrow 10-19%
with or without dysplastic changes (MPN-AP)
2.2. ≥ 20% Blasts (MPN-BP)
3. In need of treatment in the opinion of the investigator
4. Eastern Cooperative Oncology Group (ECOG) performance status 0-3
5. Platelet or red blood cell transfusion-dependent
6. Adequate liver and renal function, defined as:
6.1. Liver transaminases ≥ 3 × ULN (AST/SGOT and ALT/SGPT)
6.2. Bilirubin <4 x ULN (Patients with elevated bilirubin due to Gilbert’s syndrome are eligible)
6.3. GFR ≥ 40 ml/min
7. Willingness to undergo and ability to tolerate assessments during the study including bone marrow assessments and symptom assessments using patient reported outcome instruments

For the Observational Component
1. Age ≥ 16 years old
2. A prior diagnosis of ET, PV or MF with one of the following:
2.1. Blasts in blood or marrow 10-19%
with or without dysplastic changes (MPN-AP)
2.2 ≥ 20% Blasts (MPN-BP)
2.3. Patients who are unwilling/unable to enter the interventional component and/or fail the interventional component entry criteria. This can include patients entered into studies with more aggressive therapy such as AML 17/19 as well as those receiving palliation only

Participant type


Age group




Target number of participants

Planned Sample Size: 64; UK Sample Size: 64; Description: As this is a phase I study dose-finding study using a 3+3 cohort design, no formal power calculation has been carried out. A maximum of 24 patients and a minimum of 3 patients will be recruited. Once the MTD has been determined, an additional 10 patients will be recruited to the trial and treated at the MTD to gain further information on the safety and activity of the combined treatment. Up to 30 additional patients will be recruited into an observational component.

Participant exclusion criteria

For the Interventional Component:
1. Any co-morbidity that could limit compliance with the trial or any other condition (including laboratory abnormalities) that in the Investigators opinion will affect the patient’s participation in this trial
2.New York Heart Association Class II, III, or IV congestive heart failure
3. On-going cardiac dysrhythmias of grade 3, QTc prolongation >480 ms, or other factors that increase the risk of QT interval prolongation (e.g. heart failure, hypokalemia defined as serum potassium <3.0 mEq/L, family history of long QT interval syndrome)
4. Erythropoietic agent within 28 days prior to registration
5. Thrombopoietic agent within 14 days prior to registration
6. CYP3A4 inhibitor within 7 days prior to registration
7. Experimental treatment for AML or MPN within 14 days prior to registration (except Ruxolitinib and Hydroxycarbamide which can be taken up until study entry at the prestudy dose. Hydroxycarbamide must be stopped before the first scheduled day of treatment)
8. Previously received 5-azacitidine
9. Known contraindications to receiving azacitidine or ruxolitinib
10. Known HIV seropositivity
11. Known to have active hepatitis A, B, or C
12. Women who are pregnant or lactating. Patients of childbearing potential must have a negative pregnancy test prior to study entry
13. Patients and partners of childbearing potential not willing to use effective contraception for the duration of the study treatment and for three months after the last dose.

For the Observational Component:
No Exclusions planned.
