Brief summary
The purpose of this observational study is to investigate whether a sufficient concentration of itraconazole can influence disappearance of a fever (defeverscence) when intravenous (into the vein) itraconazole is administered for resolving unknown neutropenic fever of participants who are given itraconazole oral solution as a prophylaxis under general treatment conditions.
Detailed description
This is a prospective (study following patients forward in time), open-label (all people know the identity of the intervention), multi-center (conducted in more than one center) observational study to examine the correlation between a sufficient blood concentration of itraconazole and disappearance of a fever (defeverscence) when itraconazole injection is administered for resolving unknown neutropenic fever of participants who are given itraconazole oral solution as a prophylaxis under general treatment conditions. The recommended dose of the drug will be 200 milligram (mg), which will be administered intravenously, twice daily for 2 days (a total of 4 doses) and then 200 mg once daily for 12 days. After the administration for a total of 14 days, itraconazole oral solution 200 mg (which is equivalent to 20 ml) twice daily will be continued for a total of 14 days until clinically significant neutropenia is resolved.
Interventions
Itraconazole will be administered as an infusion (a fluid or a medicine delivered into a vein by way of a needle) over one hour at the dose of 200 milligram (mg) per dose twice daily for 2 days, followed by 200 mg once daily for 12 days, followed by itraconazole oral solution at the dose of 200 mg per dose twice daily for 14 days until clinically significant neutropenia is recovered.
