E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Primary myelofibrosis (PMF), post-polycythemia vera myelofibrosis (PPV-MF) and post-essential thrombocythemia myelofibrosis (PET-MF), collectively known as myelofibrosis (MF) |
|
E.1.1.1 | Medical condition in easily understood language |
MF is a form of bone marrow cancer in which bone marrow tissue develops in abnormal sites because the bone marrow itself undergoes fibrosis or scarring. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary aim of this study is to evaluate whether or not combining Ruxolitinib with a RIC regimen is likely to produce success after bone marrow transplantation, and thereby determine if it is a suitable treatment for patients with myelofibrosis. A RIC regimen is the chemotherapy treatment used to prepare patients for a bone marrow transplant.
Success in this trial is defined as the patient being alive, and without graft failure (when normal bone marrow function does not come back after a stem cell transplant) 100 days after the transplant. Two patient groups will be assessed independently: those who receive a related donor transplant (from a family member) and in those who receive an unrelated donor transplant, as the risk of the transplant varies markedly according to the donor type. |
|
E.2.2 | Secondary objectives of the trial |
1. The time for blood counts to recover after the transplant 2. Number of deaths due to treatment at 100 days and 1-year after treatment 3. Acute and chronic Graft versus Host Disease (GvHD) at 1-year. GvHD is caused by new donor cells treating the body as 'foreign' and launching an attack against it. 4. Chimerism studies at 30, 60 and 100 days post transplant. Chimerism studies look at who the cells in the bone marrow are originally from - either the donor or the recipient. 5. Remission (lack of disease activity) status at day 100, and 6 and 12 months post transplant 6. Disease return / worsening at 1-year post transplant 7. Survival without disease worsening at 1-year 8. Overall Survival at 1-year 9. Impact of allogeneic stem cell transplant on myelofibrosis associated symptoms and overall quality of life 10. Measurements of the levels of activity of genes (basic units of inheritance) and signalling molecules (used to send messages in the body's cells) prior to start of Ruxo |
