Scientific titleREGiME Trial: A randomised controlled trial of prolonged treatment with darbepoetin alpha (DA) with/without recombinant human granulocyte colony stimulating factor (G-CSF), versus best supportive care in patients with low-risk myelodysplastic syndromes
Study acronymREGiME
Study objectivesTo compare the haemoglobin response and quality of life of low risk myelodysplastic syndrome (MDS) patients randomised to receive prolonged treatment with darbepoetin alpha (DA) alone, DA with recombinant human granulocyte colony stimulating factor (G-CSF) or best supportive care alone.
Ethics approval(s)Not provided at time of registration
Health condition(s) or problem(s) studiedLow-risk myelodysplastic syndrome
InterventionThe 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. Response assessment will follow IWG criteria.

Arm A:
Darbepoetin alpha (Aranesp®) and best supportive care if applicable:
1. Aranesp® 500 µg subcutaneous (s.c.) once every 2 weeks:
1.1. If a rapid response is obtained (haemoglobin [Hb] increase greater than or equal to 2 g/dl in any 4 week period), titrate down the dose frequency of Aranesp®
1.2. If major response, titrate Aranesp® to lowest dose frequency that maintains the response
2. At 24 weeks:
2.1. If no response, stop Aranesp® and give supportive therapy only
2.2. If minor response, continue Aranesp® 500 µg once every 2 weeks s.c.
2.3. If major response, titrate Aranesp® to lowest dose frequency that maintains the response
3. If patients present symptoms, they will receive red cell transfusion support to achieve a predicted post–transfusion haemoglobin of 11.0 to 12.0 g/dl at a quantity and frequency such that:
3.1. The minimum haemoglobin is never below 8.0 g/dl, or
3.2. The patient is never excessively symptomatic, according to local transfusion guidelines/policy

Arm B:
Darbepoetin alpha (Aranesp®) and recombinant human granulocyte colony stimulating factor (G-CSF) and best supportive care if applicable:
1. G-CSF (Neupogen®) 300 µg s.c. twice a week, 3 - 4 days apart
2. Aranesp® 500 µg s.c. once every 2 weeks:
2.1. If a rapid response is obtained (Hb increase greater than or equal to 2 g/dl in any 4 week period), titrate down the dose frequency of Aranesp®
2.2. If major response, titrate Aranesp® and G-CSF to lowest dose frequency that maintains the response
3. At 24 weeks:
3.1. If no response, stop Aranesp® and G-CSF and give supportive therapy only
3.2. If minor response, continue Aranesp® 500 µg every 2 weeks s.c. and G-CSF 300 µg s.c. twice a week, 3 - 4 days apart
3.3. If major response, titrate Aranesp® and G-CSF to lowest dose frequency that maintains the response
4. If patients present symptoms, they will receive red cell transfusion support to achieve a predicted post-transfusion haemoglobin of 11.0 to 12.0 g/dl at a quantity and frequency such that:
4.1. The minimum haemoglobin is never below 8.0 g/dl, or
4.2. The patient is never excessively symptomatic, according to local transfusion guidelines/policy

Arm C:
Best supportive care only:
Patients randomised to no growth factor treatment will receive best supportive care only, which is defined as red cell transfusion support to achieve a predicted post-transfusion haemoglobin of 11.0 to 12.0 g/dl at a quantity and frequency such that;
1. The minimum haemoglobin is never below 8.0 g/dl, or
2. The patient is never excessively symptomatic, according to local transfusion guidelines/policy
