简要总结
This open, prospective, observational multicenter cohort study aims to evaluate the efficacy, safety as well as the effective serum concentration of Posaconazole for prevention of pulmonary fungal infections in patients with hematopoietic stem cell transplantation. The correlation of UGT1A4*3 genotype and Cmin of Posaconazole, as well as invasive fungal disease (IFD) breakthrough rates will be utilized to evaluate the efficacy while the safety of Posaconazole will be assessed by the overall incidence and severity of adverse events in patients.
详细描述
This open, prospective, observational multicenter cohort study aims to study the efficacy, safety and effective concentration of Posaconazole tablets for prevention of pulmonary fungal infection in patients with hematopoietic stem cell transplantation. A total of 360 hematopoietic stem cell transplantation patients receiving Posaconazole tablets are expected to be enrolled. Posaconazole tablets will be taken orally from the day of transplantation (300 mg Q12h D1) followed by 300 mg Qd, until 90 days after transplantation. The total duration of the study is estimated to be 24 months, with each patient participating for an estimated 3 months. The relationships between UGT1A4*3 genotype and drug serum concentration, IFD incidence, Aspergillus infection rate, IFD-related mortality rate, IFD-free survival rate, and overall survival rate will be used to evaluate the effectiveness of Posaconazole tablets in preventing invasive pulmonary fungal infection in patients with hematopoietic stem cell transplantation. Safety of Posaconazole tablet will be validated by the overall incidence and severity of adverse events in patients.

结局指标
主要结局
UGT1A4*3 genotype and plasma concentration of posaconazole
时间窗: From day 0 to day 22
Blood samples were drawn at baseline (day 0) for analysis of patients' UGT1A4\*3 genotypes and assigned to homozygous, wild-type, and heterozygous genotypes. For posaconazole serum concentrations, blood samples were collected at day 0, 4, 8, 15 and 22.
次要结局
- Measurement and record of duration of neutropenia(Duration of 90-day posaconazole prophylaxis)
- The influence of other combined medications for posaconazole plasma concentrations(Duration of 90-day posaconazole prophylaxis)
- Measurement and record of neutrophil counts(Duration of 90-day posaconazole prophylaxis)
- Plasma concentration of the patients who received different dosages of posaconazole as prophylaxis at different time points(Day 0, 4, 8, 15 and 22)
- Effect of GVHD grading on absorption and utilization of posaconazole tablets (plasma concentration)(Duration of 90-day posaconazole prophylaxis)
- Effect of diarrhea on absorption and utilization of posaconazole tablets (plasma concentration)(Duration of 90-day posaconazole prophylaxis)
- Number/Proportion of patients with immunosuppressive agent application and adjustments(Duration of 90-day posaconazole prophylaxis)
- The incidence of invasive fungal disease (IFD) and the incidence of Aspergillus infection(90 days posaconazole prophylaxis and 7 days after prophylaxis ending)
- Adverse events(Duration of 90-day posaconazole prophylaxis)
