Clinical Trial 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.


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.

Outcome

Type Measure Description Time frame Safety issue
Primary Maximum Plasma Itraconazole Concentration (Cmax) The Cmax is defined as the maximum observed analyte concentration. Cmax was measured in microgram per milliliter (mcg/ml). Day 85 for SFI (ITCZ Oral Solution Monotherapy); and Day 99 for SFI and FN Switched treatment No
Primary Area Under the Curve From Time Zero to 24 Hours Post-dose Observed Plasma Itraconazole Concentration (AUC[0-24]) The AUC(0-24) is area under the plasma concentration time curve from time zero (pre-dose) to 24 hours post-dose. It is usually calculated by linear trapezoidal method. AUC was measured in mcg*hour(hr) per ml. Day 85 for SFI (ITCZ Oral Solution Monotherapy); and Day 99 for SFI and FN Switched treatment No
Primary Minimum Inhibitory Concentration (MIC) The MIC is the lowest concentration of an antimicrobial that inhibits the visible growth of a microorganism after incubation. Day 85 for SFI (ITCZ Oral Solution Monotherapy); and Day 99 for SFI and FN Switched treatment No
Primary Maximum Plasma Drug Concentration by Minimum Inhibitory Concentration (Cmax/MIC) The Cmax is maximum observed analyte concentration and MIC is the lowest concentration of an antimicrobial that inhibits the visible growth of a microorganism after incubation. The Cmax/MIC was calculated only in participants for whom the MIC was obtained. Day 85 for SFI (ITCZ Oral Solution Monotherapy); and Day 99 for SFI and FN Switched treatment No
Primary Area Under the Curve During 24 Hours by Minimum Inhibitory Concentration (AUC 0-24/MIC) The AUC (0-24) is defined as area under the plasma concentration-time curve over the dosing interval (24 hr). It is usually calculated by linear trapezoidal method. MIC is the lowest concentration of an antimicrobial that inhibits the visible growth of a microorganism after incubation. The AUC 0-24/MIC was calculated only in participants for whom the MIC was obtained. Day 85 for SFI (ITCZ Oral Solution Monotherapy); and Day 99 for SFI and FN Switched treatment No
Primary Time Above Minimum Inhibitory Concentration (T>MIC) The T>MIC was calculated only in participants for whom the MIC was obtained. Day 85 for SFI (ITCZ Oral Solution Monotherapy); and Day 99 for SFI and FN Switched treatment No
Secondary Number of Participants With Change in Clinical Symptoms by Centralized Assessment Level of improvement in the clinical symptoms was assessed as: disappeared (if clinical symptoms disappeared), improved (significant improvement in clinical symptoms ), no change (almost no improvement in the clinical symptoms), worsened (if the clinical symptoms worsened) and could not be assessed (if it was difficult to make the above-noted assessments). Baseline up to end of treatment (Day 85 for SFI [ITCZ Oral Solution Monotherapy] and Day 99 for SFI and FN Switched treatment) No
