Primary Outcome Measures:
  • Number of Participants Who Had Clinical Response at 12 Weeks With Posaconazole Treatment [ Time Frame: Treatment week 12 ] [ Designated as safety issue: No ]

    EVALUATION OF PARTICIPANTS' CLINICAL RESPONSE BASED ON CRITERIA:

    Complete Response: resolution of Invasive Fungal Infection (IFI) attributable symptoms, signs and laboratory or etiological abnormalities, if present at enrollment.

    Partial Response: clinically significant improvement in IFI attributable symptoms, signs and laboratory or etiological abnormalities, if present at enrollment, of which, one still had not achieved complete recession.

    Stable disease: no progress in IFI attributable symptoms, if present at enrollment.

    Failure: deterioration in IFI attributable clinical symptoms.



Secondary Outcome Measures:
  • Number of Participants Who Had Clinical Response at 4 Weeks With Posaconazole Treatment [ Time Frame: Treatment week 4 ] [ Designated as safety issue: No ]

    EVALUATION OF PARTICIPANTS' CLINICAL RESPONSE BASED ON CRITERIA:

    Complete Response: resolution of IFI attributable symptoms, signs and laboratory or etiological abnormalities, if present at enrollment.

    Partial Response: clinically significant improvement in IFI attributable symptoms, signs and laboratory or etiological abnormalities, if present at enrollment, of which, one still had not achieved complete recession.

    Stable disease: no progress in IFI attributable symptoms, if present at enrollment.

    Failure: deterioration in IFI attributable clinical symptoms.


  • Number of Participants Who Had Clinical Response at 8 Weeks With Posaconazole Treatment [ Time Frame: Treatment week 8 ] [ Designated as safety issue: No ]

    EVALUATION OF PARTICIPANTS' CLINICAL RESPONSE BASED ON CRITERIA:

    Complete Response: resolution of IFI attributable symptoms, signs and laboratory or etiological abnormalities, if present at enrollment.

    Partial Response: clinically significant improvement in IFI attributable symptoms, signs and laboratory or etiological abnormalities, if present at enrollment, of which, one still had not achieved complete recession.

    Stable disease: no progress in IFI attributable symptoms, if present at enrollment.

    Failure: deterioration in IFI attributable clinical symptoms.


  • Number of Participants With Pathogenic Fungal Eradication at 4 Weeks With Posaconazole Treatment [ Time Frame: Treatment week 4 ] [ Designated as safety issue: No ]

    EVALUATION OF FUNGAL ERADICATION:

    Participants' mycological response to therapy was assessed by the following:

    Eradication: Negative culture or histologically documented absence of infecting

    fungal pathogen from a primary site previously positive.

    Presumed Eradication: Resolution of all IFI attributable symptoms, signs and laboratory or radiological abnormalities in which a repeat culture/biopsy was contraindicated.

    Persistence: Continued isolation of fungal pathogen from a primary site previously positive or cytological documentation of presence of fungal pathogen.


  • Number of Participants With Pathogenic Fungal Eradication at 8 Weeks With Posaconazole Treatment [ Time Frame: Treatment week 8 ] [ Designated as safety issue: No ]

    EVALUATION OF FUNGAL ERADICATION:

    Participants' mycological response to therapy was assessed by the following:

    Eradication: Negative culture or histologically documented absence of infecting

    fungal pathogen from a primary site previously positive.

    Presumed Eradication: Resolution of all IFI attributable symptoms, signs and laboratory or radiological abnormalities in which a repeat culture/biopsy was contraindicated.

    Persistence: Continued isolation of fungal pathogen from a primary site previously positive or cytological documentation of presence of fungal pathogen.


  • Number of Participants With Pathogenic Fungal Eradication at 12 Weeks With Posaconazole Treatment [ Time Frame: Treatment week 12 ] [ Designated as safety issue: No ]

    EVALUATION OF FUNGAL ERADICATION:

    Participants' mycological response to therapy was assessed by the following:

    Eradication: Negative culture or histologically documented absence of infecting

    fungal pathogen from a primary site previously positive.

    Presumed Eradication: Resolution of all IFI attributable symptoms, signs and laboratory or radiological abnormalities in which a repeat culture/biopsy was contraindicated.

    Persistence: Continued isolation of fungal pathogen from a primary site previously positive or cytological documentation of presence of fungal pathogen.


  • Number of Participant Survivors at Week 14 of Post-Posaconazole Treatment Follow-up [ Time Frame: Follow-up week 14 ] [ Designated as safety issue: No ]
    Total number of participant deaths was assessed at the end of 2 week post-treatment follow-up (14 weeks). The total number of deaths was compared to the number of survivors at baseline.
