Neutropenia Clinical Trial
Official title:
A Pharmacokinetic Study of JK1211 in Patients With Systemic Fungal Infection (SFI) and Patients With Febrile Neutropenia (FN) Suspected of Fungal Infection.
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.

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 |
Secondary | Number of Participants With Change in Clinical Symptoms by Diagnosis Name (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). The cases evaluated were candidemia, esophageal candidiasis, invasive aspergillosis, chronic necrotic pulmonary aspergillosis (C.N.P.A), pulmonary aspergilloma (P.A.) and pulmonary cryptococcosis (P.C). | Baseline up to end of treatment (Day 85 for SFI [ITCZ Oral Solution Monotherapy] and Day 99 for SFI Switched treatment) | No |
