Dosing Obese With Noxafil® Under a Trial (DONUT) — DONUT  

Morbid Obesity Clinical Trial

Official title:
Pharmacokinetics of Posaconazole Given as a Single Intravenous Dose to Obese Subjects: Dosing Obese With Noxafil® Under a Trial (DONUT)

Clinical Trial Summary

Although posaconazole is approved for the prophylaxes and treatment of invasive fungal infections, specific dosing guidelines for posaconazole in (morbidly) obese patients are not specified. There is clear evidence indicating that heavier patients are receiving a sub-optimal dose if the current guidelines are used. Specifically in the setting of augmented prevalence of species with intermediate susceptible to posaconazole, adequate dosing is needed at start of treatment. Therefore it seems prudent to conduct a trial in a cohort of obese patients who receive posaconazole (300mg or 400mg) and define the pharmacokinetics. These will then be compared to the pharmacokinetics in a normal-weight group receiving 300mg posaconazole.

Clinical Trial Description

Obese patients with a BMI ≥ 35 kg/m2 undergoing endoscopic gastric bypass surgery will receive a 300 mg or 400mg dose of posaconazole. A PK curve will be determined after administration at t=0.45, 0.75, 1, 1.5, 2, 4, 8, 12, 24, and (if feasible) 48 hours post infusion. Blood samples (4 mL) on PK days will be taken to obtain at least 2.0 mL of plasma. ;
