Amphotericin B for Breakthrough Fungal Infections After Triazole Prophylaxis in Hematological Patients
A Multicenter, Prospective, Observational Study to Evaluate the Efficacy and Safety of Amphotericin B in the Treatment of Breakthrough Invasive Fungal Disease in Hematological Patients Receiving Triazole Prophylaxis
The goal of this clinical trial is to learn if amphotericin B works to treat breakthrough invasive fungal disease (IFD) in patients with hematological diseases who have received azole-based prophylaxis. It will also learn about the safety of amphotericin B in this population.
The main questions it aims to answer are:
- What is the overall response rate (complete remission + partial remission) of amphotericin B in treating breakthrough IFD after azole prophylaxis?
- What medical problems do participants have when taking amphotericin B?
- What is the 6-week (42-day) overall survival rate after starting treatment?
This is a single-arm, prospective study. Participants will:
- Receive intravenous liposomal amphotericin B (3-5 mg/kg daily) for 4-6 weeks.
- Undergo weekly clinical and laboratory assessments, including serum G/GM tests, microbiology tests, and imaging (CT) at 2, 4, and 6 weeks.
- Have safety monitoring including liver and kidney function, electrolytes, and ECG.
- Be followed for treatment response and survival.
