Imatinib for Cytomegalovirus Prophylaxis and Treatment After Allogeneic Hematopoietic Stem Cell Transplantation
September 9, 2019 updated by: National Taiwan University Hospital
A Randomization, Double Blind, Multicenter Phase II Clinical Trial to Evaluate the Imatinib for Prophylaxis of CMV Infection After Allogeneic Hematopoietic Stem Cell Transplantation
This study aim at examining whether blocking platelet-derived growth factor receptor-α by imatinib lowers the risk of post-allogeneic hematopoietic stem cell transplantation CMV infection.

Detailed Description
This is a randomized, double-blind, multicenter phase II clinical trial.
In the trial, post-allo-HSCT patients with signs of bone marrow engraftment and without evidence of CMV reactivation will be enrolled.
All enrolled patients will be monitored for their blood CMV DNA copy numbers by Q-PCR and safety throughout the trial.
In addition to their routine post-allo-HSCT care, eligible patients will receive imatinib (100mg/tablet, 2 tablets daily) or placebo (2 tablets daily) administration after myeloid engraftment (defined as absolute neutrophil count higher than 500 for three consecutive days).
While receiving the trial therapy, patients will have a regular CMV surveillance every week by the quantification of plasma CMV DNA copies.
During the administration of the investigational drugs, other concomitant anti-CMV prophylaxis treatments are prohibited.
When a patient has any signs suggesting CMV infection that the treating physician determines that an anti-CMV therapy is indicated, the patient will be defined as failure of prophylaxis for the efficacy evaluation.
Whether the conventional anti-CMV therapy is started or not, the investigational drugs with imatinib or placebo will be continued till at least Day+100 unless the patient is defined as prophylaxis failure or withdraws from the study including personal reasons, early mortality, disease recurrence after transplantation, pregnancy, or the investigator decides that the subject should be withdrawn for safety reasons or physical conditions.

---|---|---|
Number of participants free from initiating conventional anti-CMV treatment by Day+100 after allo-HSCT.
Time Frame: From first dosing to 100 days after allo-HSCT (Day+100)

Measure Description |
Time Frame |
---|---|---|
Number of treatment-related adverse events (AE) by Day+100 after allo-HSCT.
Time Frame: From first dosing to 100 days after allo-HSCT (Day+100)
|
Safety profile will be evaluated according to treatment-related adverse events (AE) per CTCAE 4.03 version.
|
From first dosing to 100 days after allo-HSCT (Day+100)
|
Time to onset of CMV reactivation defined by peripheral blood CMV copies by Day+100 after allo-HSCT.
Time Frame: From first dosing to 100 days after allo-HSCT (Day+100)
