Brief Summary:
The purpose of this study was to evaluate the efficacy of eltrombopag for poor graft function (PGF) on overall hematologic response (partial and complete), as determined by platelet, hemoglobin and neutrophil counts by 16 weeks after the initiation of eltrombopag in patients with poor graft function after allogeneic hematopoietic stem cell transplantation (allo-HSCT).
Detailed Description:
This was an open-label, single-arm phase II study, in which participants diagnosed with PGF after allo-HSCT were treated with eltrombopag up to week 36 or until the participant's premature withdrawal.
The study consisted of the following periods:
* Screening Period (baseline): the participant screening criteria was reviewed, and the procedures established in the evaluation schedule were performed.
* Treatment Period: from administration of the first dose of eltrombopag until time when participant permanently stopped taking study treatment for any reason or until 36 weeks had passed. Eltrombopag was initiated on Day 1 at a dose of 150 mg once daily (75 mg daily in Asian ancestry participants). During the Treatment Period, participants were evaluated weekly during the first month, every 2 weeks during the next 2 months and subsequently every 4 weeks until week 24. For the last 3 months, participants were followed every 6 weeks Only participants who had a partial or complete response at Week 16 continued to receive eltrombopag up to Week 36 or until loss of response (defined as a decrease in blood counts to levels that did not continue to meet the criteria for response established in the protocol), unacceptable toxicity, or discontinuation for any other reason.
Participants who discontinued eltrombopag because efficacy, continued in the study and attended the scheduled visits of Treatment Period as per protocol. If loss of response occurred, eltrombopag was reintroduced at the last effective dose.
* Final Visit (or Early Withdrawal): this visit took place 30 days after completion of the Treatment Period, or premature participant withdrawal.
* Follow-up for Survival: all participants who discontinued from the study, regardless the reason of discontinuation, were followed for survival for 24 and 36 weeks, unless they withdrew their consent, died or were lost-to follow-up, in which case study visits were no longer carried out.
