Caspofungin

A Multicenter, Noncomparative, Open-label Study to Estimate the Safety, Efficacy, and Pharmacokinetics of MK-0991 (Caspofungin) in Japanese Children and Adolescents With Documented Candida or Aspergillus Infections

Invasive candidiasis: favorable overall response required resolved clinical findings and negative culture test for Candida species on follow-up. If Candida species were not observed in the baseline blood culture, favorable overall response required resolved clinical findings and resolved or improved radiographic findings. Aspergillosis: favorable overall response required resolved, improved, or unchanged clinical findings and resolved or improved radiographic findings, or resolved or improved clinical findings and resolved, improved, or stable radiographic findings.

An adverse experience (AE) is defined as any unfavorable or unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study drug. Any worsening of a preexisting condition which is temporally associated with the use of the study drug is also an AE. A drug-related AE is one judged to be definitely, probably, or possibly related to the study drug.

Candida infection is strongly suspected based on clinical symptoms and the participant's clinical course, white moss (plaque) is observed on the esophageal mucosa, and therapy via intravenous infusion is judged to be suitable for the present episode of esophageal candidiasis. MK-0991 therapy as a single loading dose of 70 mg/m^2 intravenously on Day 1 (maximum not to exceed 70 mg), followed by 50 mg/m^2 as a single once-daily dose on all subsequent days (maximum of 70 mg daily). The minimum and maximum treatment duration was 7 and 28 days, respectively.

Candida infection is strongly suspected based on the presence of refractory fever not responding to an antibiotic agent, or clinical symptoms at the site of disease, or the participant's clinical course. In addition, at least 1 of the following criteria must be met: 1) Candida infection is strongly suspected based on radiographic imaging findings and positive serological test for fungus, 2) yeast is observed by direct microscopy or histopathological test of tissue biopsied from the site of disease, or 3) Candida species are observed by culture test of specimens sampled from the site of disease. MK-0991 therapy as a single loading dose of 70 mg/m^2 intravenously on Day 1 (maximum not to exceed 70 mg), followed by 50 mg/m^2 as a single once-daily dose on all subsequent days (maximum of 70 mg daily). The minimum and maximum treatment duration was 14 and 56 days, respectively.

Aspergillus infection is strongly suspected based on clinical symptoms and the participant's clinical course, and characteristic radiographic imaging findings are observed. In addition, at least 1 of the following criteria must be met: 1) risk factors predisposing to an Aspergillus infection, 2) positive serological test for Aspergillus, 3) acute-branching mold with separated hyphae are observed by direct microscopy or histopathological test, or 4) Aspergillus species are observed by culture test. MK-0991 therapy as a single loading dose of 70 mg/m^2 intravenously on Day 1 (maximum not to exceed 70 mg), followed by 50 mg/m^2 as a single once-daily dose on all subsequent days (maximum of 70 mg daily). The minimum and maximum treatment duration was 14 and 84 days, respectively.

No participants with esophageal candidiasis were identified for inclusion in the study and assessment for adverse events

MK-0991 therapy as a single loading dose of 70 mg/m\^2 intravenously on Day 1 (maximum not to exceed 70 mg), followed by 50 mg/m\^2 as a single once-daily dose on all subsequent days (maximum of 70 mg daily). The minimum and maximum treatment duration was 14 and 56 days, respectively.

The full analysis set included all enrolled participants who received \>=1 dose of study drug. No participants with esophageal candidiasis were identified for inclusion in the study and assessment for response to therapy. Participants whose overall response assessment was "unable to judge" were counted as having an unfavorable response.

Percentage of Participants With an Overall Favorable Response to Therapy

The full analysis set included all enrolled participants who received \>=1 dose of study drug. No participants with esophageal candidiasis were identified for inclusion in the study and assessment for safety outcomes.

Percentage of Participants With One or More Drug-Related Adverse Experiences

MK-0991 therapy as a single loading dose of 70 mg/m\^2 intravenously on Day 1 (maximum not to exceed 70 mg), followed by 50 mg/m\^2 as a single once-daily dose on all subsequent days (maximum of 70 mg daily). The minimum and maximum treatment duration was 7 and 28 days, respectively.
