Official Title: Steady-State Comparative Bioavailability Study in Patients Requiring Anti-Fungal Prophylaxis Comparing Twice a Day Dosing of Lozanoc® (Mayne) Regardless of Food With Sporanox® (Janssen) Unde

Brief Summary: The pharmacokinetics of Sporanox and Lozanoc has not been compared in patients requiring anti-fungal prophylaxis or therapy. The present study is designed to compare the pharmacokinetics of Sporanox and Lozanoc in patients requiring primary prophylaxis. The 3-week exposure to each formulation is designed to allow for all participants to reach steady-state for each drug, as the time to steady-state can vary.

Detailed Summary:

After confirmation of eligibility, participants will be randomly assigned 1:1 to commence therapy with either 100mg mane and 100mg nocte for 21 days or Sporanox 200mg mane and 200mg nocte with food for 21 days. If a subject enters the study already receiving itraconazole prophylaxis at a dose of itraconazole higher than 100 mg twice a day, the subject will then be dosed on study at the pre-study dosage; that is, the subject will take the same number of capsules per day on study as the subject was taking prior to enrolment in the study.

The following information will be collected at baseline; whether the participant is taking itraconazole prophylaxis and at what dose; whether the participant is taking gastric suppression therapy. Patients who are not taking food or who are taking gastric acid suppression therapy (antacids, an H2 antagonist or a proton pump inhibitor) can take Sporanox with cola or orange juice to maximise absorption as recommended in the Sporanox product label (not required for Lozanoc formulation).

At Day 22, participants assigned to

• Lozanoc and who have completed 21 days of Lozanoc prophylaxis will cross over to the same number of Sporanox capsules with food for a further 21 days
• Sporanox and who have completed 21 days of Sporanox prophylaxis will cross over to the same number of Lozanoc capsules for a further 21 days.

The dose of either drug may be dose-reduced or ceased for toxicity at the discretion of the investigator.

During the course of the treatment periods participants will undergo the following assessments:

• Same as current
