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.
    

Eligibility criteria:

        Inclusion Criteria:

          -  Weight >40 kg (88 lb) and ≤150 kg (330 lb); if between 13 and 14 years of age must
             weigh >= 50 kg (110 lb)

          -  Must meet the criteria for proven, probable, or possible IA as per 2008 European
             Organization for Research and Treatment of Cancer/Invasive Fungal Infections
             Cooperative Group and the National Institute of Allergy and Infectious Diseases
             Mycoses Study Group (EORTC/MSG) disease definitions at the time of randomization.
             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

        Exclusion Criteria:
