About this trial

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:

1. What is the overall response rate (complete remission + partial remission) of amphotericin B in treating breakthrough IFD after azole prophylaxis? 2. What medical problems do participants have when taking amphotericin B? 3. What is the 6-week (42-day) overall survival rate after starting treatment?

This is a single-arm, prospective study. Participants will:

1. Receive intravenous liposomal amphotericin B (3-5 mg/kg daily) for 4-6 weeks. 2. Undergo weekly clinical and laboratory assessments, including serum G/GM tests, microbiology tests, and imaging (CT) at 2, 4, and 6 weeks. 3. Have safety monitoring including liver and kidney function, electrolytes, and ECG. 4. Be followed for treatment response and survival.

Trial outcomes

Primary outcomes

1

Overall Response Rate of Antifungal Therapy at 6 Weeks (42 Days)

The overall response rate will be assessed at 6 weeks (42 days) after the initiation of amphotericin B treatment, evaluated according to the EORTC/MSG 2020 criteria for invasive fungal disease, including complete response, partial response, stable disease, and progressive disease.

Time frame
6 weeks (42 days) after treatment initiation

Secondary outcomes

1

Overall Survival Rate at 6 Weeks

Proportion of participants alive at 6 weeks (42 days) after initiation of amphotericin B therapy.

Time frame
6 weeks (42 days) after treatment initiation
2

Change in serum G test level

Change from baseline in serum (1,3)-β-D-glucan level. Unit of measure: pg/mL.

Time frame
From enrollment to the end of 6-week treatment
3

Change in serum GM test level

Change from baseline in serum galactomannan test value. Unit of measure: ug/L.

Time frame
From enrollment to the end of 6-week treatment
4

Microbiological clearance

Proportion of participants with negative conversion of baseline positive microbiological evidence (e.g., blood culture, sputum culture, mNGS, or site smear/culture).

Time frame
From enrollment to the end of 6-week treatment
