Treating breakthrough invasive fungal infections in blood cancer patients with liposomal amphotericin B versus isavuconazole/posaconazole

The Efficacy and Safety of Liposomal Amphotericin B and Isavuconazole/Posaconazole in the Treatment of Breakthrough Invasive Fungal Disease in Patients With Malignant Hematological Diseases After Antifungal Prophylaxis

Observational Institute of Hematology & Blood Diseases Hospital, China · NCT07135778

This project will test whether liposomal amphotericin B or isavuconazole/posaconazole works better and is safer for adults with blood cancers who develop breakthrough invasive fungal infections after antifungal prophylaxis.

What this trial studies

This is a prospective, open-label, controlled, single-center observational study enrolling adults with hematologic malignancies who develop breakthrough invasive fungal disease after at least 7 days of echinocandin or triazole prophylaxis. Treatment choice is determined by the treating clinician and patients receive either liposomal amphotericin B or an azole (isavuconazole or posaconazole), with 36 patients planned for each treatment group. The study will record clinical outcomes including overall response, survival, time to fever resolution, and length of hospital stay, and will systematically capture adverse events and drug-related toxicity. Analyses will compare efficacy and safety between the two treatment approaches and explore differences across subgroups such as age, sex, and underlying hematologic diagnosis.

Who should consider this trial

Good fit: Adults (age ≥18) with hematologic malignancies—commonly AML, ALL, or MDS—who develop proven, probable, or possible breakthrough invasive fungal disease after ≥7 days of antifungal prophylaxis and can give informed consent.

Not a fit: Patients under 18, those without breakthrough IFD per the guideline definitions, or those with documented allergy to the study antifungals are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the findings could clarify which antifungal approach provides better outcomes and safer care for breakthrough invasive fungal infections in patients with blood cancers.

How similar studies have performed: Liposomal amphotericin B and modern azoles each have established activity in invasive fungal disease, but direct, real-world head-to-head comparisons for breakthrough IFD in hematologic patients are limited.
