| Scientific title | A randomised controlled trial of prolonged treatment with darbepoetin alpha (EPO), with or without recombinant human granulocyte colony stimulating factor (G-CSF), versus best supportive care in patients with low-risk myelodysplastic syndromes (MDS) |
| Study acronym | REGiM |
| Study objectives | Myelodysplastic syndromes (MDS) are acquired clonal disorders of the bone marrow. The clinical consequences of MDS are bone marrow failure and a predisposition to develop acute myeloid leukaemia (AML). Patients with 'low risk MDS' have less than 10% myeloblasts in the marrow and include the World Health Organization (WHO) subtypes refractory anaemia (RA), refractory anaemia with ring sideroblasts (RARS) and refractory anaemia with excess blasts-I (RAEB-I). This group of patients have a relatively low risk of leukaemic transformation and the major clinical problem is the manifestations of bone marrow failure. Up to 80% of these patients become red cell transfusion dependent. To date the only curative therapy is allogeneic stem cell transplantation. Unfortunately, a median age at diagnosis of more than 65 years excludes this type of therapy for most patients with MDS. The aim of treatment is, therefore, supportive therapy (long term red cell transfusions). In this clinical study we are investigating if treatment with an erythropoiesis stimulating agent (darbepoetin alpha) with or without G-CSF therapy can increase haemoglobin concentration and reduce/eliminate red cell transfusion in selected patients with MDS. Our primary endpoints include a measure of erythroid response and quality of life to see if treatment with darbepoetin alpha with/without G-CSF is more effective than best supportive care (long term red cell transfusions). The trial is a multi-centre, randomised, triple arm, open-label study. We aim to open 40 sites in the UK in the first instance recruiting 360 patients in total. When the eligibility is confirmed, patients will be randomised within 42 days into a 1:1:1 ratio to either: 1. Arm A: Darbepoetin alpha and best supportive care 2. Arm B: Darbepoetin alpha with G-CSF and best supportive care 3. Arm C: Best supportive care only |
| Ethics approval(s) | Brighton East Research Ethics Committee approved on the 8th November 2004 (ref: 04/Q1907/94) |
| Health condition(s) or problem(s) studied | Topic: National Cancer Research Network; Subtopic: Haematological Oncology; Disease: Leukaemia (acute myeloid) |
| Intervention | The treatment schedule uses the concept of 'frontloading' to give patients the highest doses of DA at the start of therapy in order to induce a response as quickly as possible. The long-acting nature of darbepoetin alpha avoids excessive frequency of injections, but allows delivery of high doses of ESA. At week 24, if no response is achieved, the study treatment is deemed to have failed and is stopped and patients will receive 'best supportive care' only. Arm A: Darbepoetin Alpha (Aranesp®) 500 mcg subcutaneously (s.c.) once every 2 weeks Arm B: Aranesp® and G-CSF (Neupogen®) 300 mcg s.c. twice a week, 3 - 4 days apart Arm C: Best supportive care; patients randomised to no growth factor treatment Study entry: registration and one or more randomisations |
