Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Lenalidomide will be commenced orally at a dose of 10mg daily for 6 weeks following stem cell transplant. If this dose is well tolerated it may be increased at the discretion of the attending haematologist 2 months following commencement. Converseley, in patients with suspected lenalidomide toxicity, dose reductions in 5mg steps will be allowed for management of myelo-suppression. Dose re-escalation of lenalidomide at the discretion of the attending haematologist will be allowed subsequently where toxicity abates.
Alternate-day prednisolone will start at a dose of 50mg. No escalation of prednisolone will be allowed to manage toxicities. Patients intolerantof prednisolone can continue on single agent lenalidomide.

Summary
Brief summary
A post stem cell transplant maintenance study with lenalidomide in combination with alternate day prednisolone.
All patients will be registered prior to stem cell transplant, be planned for single high dose Melphalan-conditioned stem cell transplant and have no evidence of disease progression at re-staging 6 weeks post transplant.
Oral lenalidomde will commence at a dose of 10mg daily. After 2 months following commencement, escalation or reduction of lenalidomide can be made at the discretion of the treating doctor, depending on tolerance or intolerance of the treatment. Alternate day prednisolone will commence at a dose of 50mg on alternate days with lenalidomide. No dose escalation of prednisolone is planned. Dose reductions are permitted to manage any side effects according to the study protocol. This treatment will continue until unacceptable side effects or disease relapse/progressive disease.
Pre transplant, all patients will undergo disease restaging with blood tests and bone marrow aspirate. Bloods for serum storage for DNA analysis will be obtained. 6 weeks post transplant patients with adequate recovery will undergo rstaging of their disease with blood testing and bone marrow, to confirm continuing disease response. Patients with disease progression evident on re-staging will not be eligible for treatment on this study. On study, all patients will continue to be evaluated every 4 weeks with repeat blood testsfor response and monitoring until disease progression.
