Using ROMIPLOSTINE for Persistent Thrombocytopenia With Transfusion-dependent Patients Who Received Allogeneic Hematopoietic Stem Cell (AGRAH003)
This is a Phase I/II multicenter study which aims to assess the toxicity profile of Romiplostim in patients with transfusion-dependent thrombocytopenia after allogeneic HSCT.
A total of 24 patients with transfusion-dependent thrombocytopenia after allogeneic HSCT will be included.
The main endpoint is the incidence and severity of adverse events.

- Adequate liver function
- Serum creatinine ≤ 176.8 μmol/L
- Bone marrow aspirate with cytogenetics within 6 days of the first dose of romiplostim
- Written informed consent
Exclusion Criteria:
- Relapse/progression of hematological malignancy (marrow examination required)
- Non-controlled acute and/or chronic graft versus host disease (GvHD)
- Active or uncontrolled infections
- Cardiac pathology - Thrombosis
- Pregnancy or breast feeding
- Received interleukin-11 (IL-11) within 4 weeks of screening or previously received any thrombopoietic growth factor
- Patients on anticoagulant therapy
- Receipt or planned receipt of Pegylated Granulocyte Colony Stimulating Factor (PEG-G-CSF), or Granulocyte macrophage-colony stimulating factor (GM-CSF) within 4 weeks of the first dose of investigational product
- Subject not using adequate contraceptive precautions, in the judgment of the investigator
- Sensitivity to any Escherichia coli-derived product
- Inability to comply with study procedures.
