Fungal Infections, Invasive Pulmonary Aspergillosis
Conditions
Brief summary
The purpose of this study is to evaluate the safety and efficacy of posaconazole (POS) versus voriconazole (VOR) in the treatment of adults and adolescents with invasive aspergillosis (IA). The primary hypothesis is that the all-cause mortality through Day 42 in the POS treatment group is non-inferior to that in the VOR treatment group.

Proven IA will include those participants with the demonstration of fungal elements (by cytology, microscopy, or culture) in diseased tissue (sterile sampling). Probable IA includes participants with at least 1 host factor, clinical criteria, as well as mycological criteria including both direct and indirect methods. Possible IA includes participants with at least 1 host factor and clinical criteria but without mycological criteria. A modification to the 2008 EORTC/MSG criteria regarding risk factors has been made to allow for the inclusion of participants with any duration of neutropenia as an acceptable inclusion host factor. * If with possible IA at time of randomization must be willing or be in process of an ongoing diagnostic work up which is anticipated to result in a mycological diagnosis of proven or probable IA postrandomization. * Must have a central line (e.g., central venous catheter, peripherally-inserted central catheter, etc.) in place or planned to be in place prior to beginning IV study therapy. If without central catheter access, must be clinically stable and able to receive oral study therapy. * Acute IA defined as duration of clinical syndrome of \<30 days. * Must be willing to adhere to dosing, study visit schedule, and mandatory procedures as outlined in the protocol. The participant must be willing to continue on study therapy for up to 12 weeks and remain in the study through the 1-month follow-up visit. * The participant must have the ability to transition to oral study therapy during the course of the study. * Female participants of child-bearing potential must be using a medically accepted method of birth control before beginning study-drug treatment and agree to continue its use for 30 days after stopping study medication * Is not taking prohibited antifungal prophylaxis or treatment

Secondary
Steady State Average Concentration (Cavg) of Posaconazole With Food Intake
The characterization of the pharmacokinetics (PK) parameters of POS was determined from plasma samples taken at steady-state after receiving oral tablet of POS. Steady-state Cavg, where Cavg is defined as area under the concentration time-curve from 0 to 24 hours (AUC0-24hr) divided by the dosing interval. Data is presented in POS group column only. No evaluation of food intake on the VOR capsule was presented.
Time frame: Baseline, and at pre-dose on Day 7, Week 2, Week 4, Week 6, and Week 12
Population: The analysis population consisted of all randomized participants in the POS group only who received at least one dose of study treatment. Per protocol, the VOR group was not included in the analysis population because the food intake evaluation was limited to the POS group.
