Treatments tested in this trial
Romiplostim N01
DrugRomiplostim N01 was administered subcutaneously once weekly from +1 day to +28 days after UCBT at a recommended starting dose of 5µg/Kg (maximum single dose not to exceed 250µg) for a total of 4 administrations, with the option of continuation of dosing/switching/discontinuing after +28 days, depending on the patient's platelet profile.

Trial outcomes
Primary outcomes
Time of platelet engraftment
Platelet engraftment is defined as independence from platelet transfusion for at least 7 days with a platelet count of more than ≥20 × 10\^9/L.
The cumulative incidence of platelet engraftment at 28 days after transplantation
Platelet engraftment is defined as independence from platelet transfusion for at least 7 days with a platelet count of more than ≥20 × 10\^9/L.
Secondary outcomes
The cumulative incidence of platelet recovery rate at 28 days after transplantation
Platelet recovery was defined as independence from platelet transfusion for at least 7 days with a platelet count of more than ≥50×10\^9/L.
Time of platelet recovery
The Median time of platelet count ≥20×10\^9/L, 50×10\^9/L, 100×10\^9/L without platelet transfusions
Total platelet transfusion during 4 weeks of treatment
Total platelet transfusion during 4 weeks of treatment
Cumulative implantation rate of the granulocyte lineage at 28 days post-transplantation
Absolute neutrophil count (ANC) ≥0.5×10\^9/L for 3 consecutive days
