Invasive Fungal Disease
Conditions
Brief summary
This is a prospective, open label, controlled, single center real-world observational study. Adult (aged ≥ 18 years) patients with hematological malignancies develop breakthrough invasive fungal disease after receiving ≥ 7 days of echinocandin or triazole antifungal prophylaxis receive treatment with liposomal amphotericin B or treatment with Isavuconazole or posaconazole according to the clinical doctor's decision. It is planed to collect 36 patients receiving treatment with liposomal amphotericin B and 36 patients receiving treatment with Isavuconazole or posaconazole, and observe their efficacy and safety.
Detailed description
This is a prospective, open label, controlled, single center real-world observational study. Adult (aged ≥ 18 years) patients with hematological malignancies develop breakthrough invasive fungal disease after receiving ≥ 7 days of echinocandin or triazole antifungal prophylaxis receive treatment with liposomal amphotericin B or treatment with Isavuconazole or posaconazole according to the clinical doctor's decision. It is planed to collect 36 patients receiving treatment with liposomal amphotericin B and 36 patients receiving treatment with Isavuconazole or posaconazole, and observe their efficacy and safety. The research objective of this study is to: 1. Evaluate efficacy: The main objective is to determine the therapeutic effect of L-AmB (liposomal amphotericin B) or Isavuconazole/posaconazole on breakthrough invasive fungal disease, including percentage of patients with favorable overall response, survival rate, median to fever remission time, length of hospital stay, etc.2. Evaluate safety: Study the safety of drugs, including monitoring and recording all adverse events, side effects, and drug-related toxicity. 3. Patient population analysis: Study the differences in response to treatment with liposomal amphotericin B and Isavuconazole/posaconazole among different patient populations (such as different ages, genders, and underlying disease states). These research objectives will contribute to a comprehensive understanding of the roles of L-AmB and Isavuconazole/posaconazole in the treatment of breakthrough fungal infections, and provide scientific evidence for clinical practice.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The favorable overall responses rate at the end of treatment (proportion of patients achieving complete or partial remission) | through study completion, an average of 2 weeks | The end of treatment refers to the time when L-AmB or Isavuconazole/posaconazole treatment ends. According to the EORTC/MSG (European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycosis Study Group)efficacy evaluation criteria based on clinical evaluation, the response is divided into complete remission, partial remission, disease stability, disease progression, and death directly related to the study drug or IFD(invasive fungal disease). Effective refers to complete and partial remission. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Survival rate at key time points | through study completion, an average of 2 weeks | proportion of participants alive at (1) end of treatment (2) 42 days post-therapy (3)84 days post-therapy. Survival is defined as being free from death due to any cause |
| Time to favorable overall response | 14 days | Duration from study enrollment to achievement of a favorable overall response (complete or partial resolution of mucormycosis symptoms, radiological improvement, and microbiological clearance) |
| Length of hospitalization | 30 days | Total number of days participants spend hospitalized from enrollment until discharge or death. |
| incidence of treatment-emergent adverse events | 30 days | incidence and severity of treatment-emergent adverse events(TEAEs), including nephrotoxicity, hepatotoxicity, infusion reactions, and electrolyte abnormalities, graded per CTCAE V5.0(National Cancer Institute - Common Terminology Criteria for Adverse Events Version 5.0) criteria. |
