Allocation: NON_RANDOMIZED | Intervention model: PARALLEL
Enrollment: 55
Healthy volunteers: no

Brief summary:
The purpose of this study is to assess the pharmacokinetics (how the drug is absorbed in the body, distributed within the body, and how it is removed from the body over time) of itraconazole (ITCZ) oral solution in participants with Systemic Fungal Infection (SFI) and those with febrile (with fever) neutropenia (FN, decrease in white blood cells) suspected of fungal infection.

Detailed description:
This is an open-label (all people know the identity of the intervention), multicenter (conducted in more than 1 center) and uncontrolled (no competitive drugs involved) study. Participants with SFI will receive treatment with ITCZ oral solution or switch treatment from intravenous (into a vein) infusion of itraconazole (ITCZ-intravenous) to ITCZ oral solution as per Investigator's discretion. All the participants with FN suspected of fungal infection will receive the switch treatment from ITCZ- intravenous to ITCZ oral solution. The study will include 3 periods: Pre-observation period (7 days), Treatment period (85 days for ITCZ oral solution monotherapy and 99 days for switch treatment) and Follow-up observation period (30 days). The participants who receive ITCZ oral solution monotherapy will receive ITCZ oral solution without ITCZ-intravenous in the dose range of 20 milliliter (ml) per day to 40 ml per day for 12 weeks (85 days) and those on the switch treatment will receive 400 milligram (mg) per day ITCZ-intravenous twice for first 2 days followed by 200 mg per day ITCZ-intravenous up to 14 days and then they will be administered treatment as per ITCZ oral solution monotherapy. Efficacy will primarily be evaluated by assessing the pharmacokinetics. Participants' safety will be monitored throughout the study.

Arms:
arm 1: Participants with deep-seated mycosis (Systemic Fungal Infection \[SFI\]) received itraconazole (ITCZ) oral solution in the dose range of 20 milliliter (ml) per day to 40 ml per day for 12 weeks as per Investigator's discretion. arm 2: Participants with SFI received 200 milligram (mg) twice daily itraconazole intravenous (into the vein) infusion (ITCZ-IV) for first 2 days followed by 200 mg per day ITCZ-IV up to 14 days. Participants then received ITCZ oral solution in the dose range of 20 ml per day to 40 ml per day for 12 weeks as per Investigator's discretion. arm 3: Participants with febrile neutropenia (FN) with suspected fungal infection received 200 mg twice daily ITCZ-IV for first 2 days followed by 200 mg per day ITCZ-IV up to 14 days. Participants then received ITCZ oral solution in the dose range of 20 ml per day to 40 ml per day for 12 weeks as per Investigator's discretion.

Interventions: intervention 1: ITCZ Oral Solution intervention 2: ITCZ-IV
Intervention descriptions: intervention 1: ITCZ syrup product containing ITCZ 10 mg per ml in dose range of 20 ml to 40 ml daily for 7 days up to 12 weeks intervention 2: 200 mg IV twice daily for 2 days and once daily for the next 1 to 12 days
