Pharmacokinetics of Posaconazole Prophylaxis in Acute Leukemia
The goal of this clinical research study is to learn the amount of posaconazole that is in the body at different time points when given to patients with leukemia. The safety of this drug will also be studied.
To study the plasma pharmacokinetics of posaconazole in patients with newly diagnosed acute myelogenous leukemia (AML) or high-risk myelodysplastic syndrome (HR-MDS) undergoing induction chemotherapy or relapsed or refractory patients who will receive salvage chemotherapy.
To evaluate the safety of posaconazole given as prophylaxis.
|Study Design:||Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
|Official Title:||Phase II Study of the Pharmacokinetics of Posaconazole Prophylaxis in Relapsed or Refractory Patients With Acute Leukemia|
- Maximum Observed Concentration in Plasma (Cmax) [ Time Frame: Pharmacokinetics: Day 1, Day 3 and Day 10 of prophylaxis. ]
Pharmacokinetic samples were obtained on day 1, day 3 and day 10 of prophylaxis. A total of 15 samples (3 ml each sample) per participant were obtained, with thrice daily dosing planned around standard meal times. On day 1 and day 3 of prophylaxis sampling was done pre dose (0), and at 3, 5, 10 and 24 hours (±10 minutes) post dose from the time of the first dose of the day. On day 10 of prophylaxis sampling was done pre dose (0), and at 3, 5, and 10 hours (±10 minutes) post dose from the time of the first dose of the day.
Posaconazole levels were assayed by high performance liquid chromatography (HPLC). The testing range for posaconazole is from 125 - 5000 ng/ml. There are no established therapeutic ranges for posaconazole.
