Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Phase I dose escalation study of micro-dose oral lenalidomide as maintenance therapy after allogeneic stem cell transplantation for patients with AML or MDS at high risk of relapse.

Participants commence lenalidomide oral tablets from day 40 post-allogeneic transplant, as per the dosing levels described below:
Dose level 1: lenalidomide 2.5mg oral weekly
Dose level 2: lenalidomide 2.5mg oral twice per week
Dose level 3: lenalidomide 5mg oral twice per week
Dose level 4: lenalidomide 5mg oral every second day
Dose level 5: lenalidomide 10mg oral every second day

Treatment will continue for up to 48 weeks unless there is disease progression or unacceptable toxicity. Intervention adherence will not be routinely assessed.

Outcomes
Primary outcome [1] 319594 0
The composite incidence of death, grade 3-4 infection, grade 3-4 acute GVHD, grade 3-4 haematologic and non-haematologic toxicity

Outcome definitions:
Acute GVHD will be assessed according to consensus criteria (Glucksberg criteria)
Grade 3-4 infection, haematologic toxicity and non-haematologic toxicity are defined according to CTCAE v4.0 criteria
Timepoint [1] 319594 0
120 days after initiation of lenalidomide
Secondary outcome [1] 368817 0
Overall survival, defined as the time from transplant to the date of death from any cause
Timepoint [1] 368817 0
1 year post-transplant
Secondary outcome [2] 369098 0
Progression-free survival defined as the time from transplant to leukaemia progression or death, whichever comes first. Leukaemia progression will be defined as the presence of circulating leukaemia blasts, bone marrow blasts greater than 5% of total cellularity or the presence of new extramedullary leukaemia.
Timepoint [2] 369098 0
1 year post-transplant
