A significant drug-related adverse experience was defined as a serious drug-related adverse experience or a drug-related adverse experience leading to study therapy discontinuation.
A serious adverse event is one that results in death, disability/incapacity, or hospitalization or is life threatening, a congenital anomaly or birth defect, cancer, an overdose, or otherwise jeopardizes the patient and may require medical intervention. A drug-related adverse event is a determination by the investigator physician that the study drug caused the event based on exposure, time course, likely cause, dechallenge (event resolved/improved when drug was discontinued), rechallenge (event resolved/improved when drug was re-introduced), and consistency with the drug profile.
Number of patients with at least 1 significant drug-related adverse event (serious drug-related or drug-related adverse events leading to caspofungin discontinuation) while on caspofungin study therapy or during the immediate 14-day post-caspofungin therapy period.
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.

| 2 | EXPERIMENTAL | 150 mg intravenous (IV) infusion (diluted with 9% saline) administered daily, over the course of \~2 hrs. all patients should be treated with antifungal therapy for at least 14 days following both the improvement in clinical and radiographic signs of disease and the eradication of Candida from culture samples obtained from the invasive site of infection. |
| Participants with Esophageal Candidiasis | EXPERIMENTAL | 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. |
| Participants with Invasive Candidiasis | EXPERIMENTAL | 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. |
| Participants with Aspergillosis | EXPERIMENTAL | 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. |

Caspofungin is an investigational small molecule being studied for the treatment of fungal infections, including invasive candidiasis, candidiasis, esophageal candidiasis, aspergillosis, and infections in neutropenic patients. It is being evaluated in pediatric and adult populations with documented Candida or Aspergillus infections.
Caspofungin is being developed by Merck & Company, Inc., which trades under the ticker symbol MRK on the New York Stock Exchange. The company is conducting clinical trials to evaluate the drug's safety and efficacy in treating fungal infections.
Caspofungin is in Phase 2 clinical development. It is an investigational drug and has not been approved by regulatory authorities. All four clinical trials listed for Caspofungin are Phase 2 studies that have been completed.
Caspofungin has completed four Phase 2 clinical trials: NCT00082524 in pediatric patients with Candida or Aspergillus infections, NCT00082537 comparing it to amphotericin B in febrile neutropenic patients, NCT00330395 a pharmacokinetic study in neonates and infants, and NCT01165320 in Japanese children and adolescents.
Caspofungin is a small molecule antifungal agent. It works by inhibiting the synthesis of beta-glucan, a key component of fungal cell walls, which leads to fungal cell death. This mechanism targets the fungal cell wall specifically, making it effective against Candida and Aspergillus species.
Yes, Caspofungin is also known as MK-0991. Clinical trial records reference the drug under both names, with studies such as NCT01165320 titled 'A Study of Caspofungin (MK-0991) in Japanese Children and Adolescents.'
