About this study

Official title: 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.

Read the 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mortality, disease recurrence after transplantation, pregnancy, or the investigator decides that the subject should be withdrawn for safety reasons or physical conditions.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of participants free from initiating conventional anti-CMV treatment by Day+100 after allo-HSCT.

    Investigator determined whether anti-CMV treatment is needed or not based on clinical judgment no matter therapeutic or preemptive treatment. Symptomatic CMV infection or CMV organ disease was defined as described by Ljungman et al., 2002.

    Measured: From first dosing to 100 days after allo-HSCT (Day+100)

Secondary outcomes (5)
  1. Number of treatment-related adverse events (AE) by Day+100 after allo-HSCT.

    Safety profile will be evaluated according to treatment-related adverse events (AE) per CTCAE 4.03 version.

    Measured: From first dosing to 100 days after allo-HSCT (Day+100)

  2. Time to onset of CMV reactivation defined by peripheral blood CMV copies by Day+100 after allo-HSCT.

    The peripheral blood CMV DNA copy numbers (copies/mL) were determined using a commercial kit with PCR method following its protocol. The CMV copy numbers are monitored on a weekly basis.

    Measured: From first dosing to 100 days after allo-HSCT (Day+100)

  3. Time to onset of CMV disease diagnosed by investigator by Day+100 after allo-HSCT.

    The diagnosis of CMV disease is based on clinical practice and the invasive procedure was encouraged to make the definite diagnosis. The reference to CMV organ disease definition was described by Ljungman et al., 2002.

    Measured: From first dosing to 100 days after allo-HSCT (Day+100)

  4. Number of participants who had progressive hematological disease within 6 months after allo-HSCT.

    Defined as any subject that is known to have a progressive hematological disease.

    Measured: 6 months post-transplant

  5. Number of participants who died within 6 months after allo-HSCT.

    Defined as any subject that is known to be dead.

    Measured: 6 months post-transplant

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Imatinib in people with Patients Who Have Received Allo-HSCT, run by National Taiwan University Hospital at 5 sites in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 11 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: The trial is terminated due to the extremely low recruitment rate.). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

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)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Sep 2019.
