Summary

This clinical trial, a single-arm prospective study, aims to evaluate the efficacy and safety of liposomal amphotericin B (3-5 mg/kg/day) combined with posaconazole/isavuconazole in treating adult patients with malignant hematological diseases complicated by mucormycosis. The primary objectives are to determine the proportion of patients achieving complete or partial resolution of mucormycosis symptoms and to identify prognostic factors influencing survival outcomes. Participants will receive the combination therapy, undergo regular monitoring of symptoms, adverse events, and disease progression via radiological and laboratory assessments, and complete follow-up visits to track long-term survival. The study will analyze composite response rates, treatment-related adverse events, and survival data to refine therapeutic strategies for this high-risk population.

Detailed description

This research aims to test whether combining two antifungal medications-liposomal amphotericin B (given through an IV) and either posaconazole or isavuconazole (available as IV or oral pills)-can effectively and safely treat adults with blood cancers (like leukemia or lymphoma) who develop a severe fungal infection called mucormycosis. Current guidelines often recommend amphotericin B-based therapies, but optimal dosing, combinations, and treatment duration remain unclear. This study will provide critical data on whether a regimen of liposomal amphotericin B (3-5 mg/kg/day) paired with newer antifungals (posaconazole/isavuconazole) can enhance outcomes. It will also identify which patient characteristics (e.g., age, cancer type, recovery speed) most strongly affect survival, helping doctors personalize care.

Interventions

Type	Name	Description
DRUG	liposomal amphotericin B (3-5 mg/kg/day) combined with posaconazole/isavuconazole	The intervention in this study is a tailored antifungal regimen combining liposomal amphotericin B (L-AmB) (3-5 mg/kg/day IV) with posaconazole or isavuconazole (300 mg/200 mg daily, oral or IV), designed to optimize efficacy and safety in immunocompromised adults with blood cancers and mucormycosis. Dosing and duration are personalized based on clinical response, immune recovery, and organ function, with a focus on transitioning to oral therapy to reduce hospitalization. The study emphasizes rigorous safety monitoring, prohibited unauthorized antifungal co-medications, and explores prognostic factors to advance treatment strategies for this high-risk population.
