High-dose Liposomal Amphotericin B for treating disseminated histoplasmosis in AIDS patients

Efficacy and Safety of High-dose Liposomal Amphotericin B (10 Mg/kg) for Disseminated Histoplasmosis in AIDS: a Randomized Phase III Trial (INDUCTION Trial)

Phase 3 Interventional Federal University of Health Science of Porto Alegre · NCT05814432

This study is testing if a single high dose of a medication can safely treat disseminated histoplasmosis in AIDS patients better than the usual lower dose given over two weeks.

What this trial studies

This phase III trial evaluates the safety and efficacy of a single high dose of liposomal amphotericin B (10 mg/kg) compared to the standard therapy dose (3 mg/kg for two weeks) in patients with disseminated histoplasmosis associated with AIDS. The study aims to determine non-inferiority in terms of two-week mortality and superiority in a Desirability of Outcome Ranking (DOOR). It includes adult patients diagnosed with disseminated histoplasmosis, confirmed through various mycological methods. The trial will also establish a Data Safety Monitoring Board to oversee participant safety and efficacy throughout the study duration.

Who should consider this trial

Good fit: Ideal candidates are adult patients with HIV who have been diagnosed with disseminated histoplasmosis.

Not a fit: Patients with previous diagnoses of histoplasmosis or those with renal failure may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a more effective and accessible option for patients suffering from disseminated histoplasmosis in the context of AIDS.

How similar studies have performed: Previous phase II trials have shown promising results with high-dose liposomal amphotericin B, indicating potential success for this approach.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Adult patients admitted to the centers that will be part of the study
* Infected by the HIV, regardless of the use of antiretroviral therapy
* Patients diagnosed with disseminated histoplasmosis, confirmed by classical mycological methods (microscopy, culture or histopathology) or urinary Histoplasma antigen detection
* Patients with central nervous system (CNS) infection may be included if they have an alternative diagnosis suggestive of another CNS infection
* Patients using fluconazole for oroesophageal candidiasis may be included

Exclusion criteria:

* Refusal to participate in the trial
* Previous diagnosis of histoplasmosis
* Pregnant or lactating women
* Patients with renal failure at any given time (serum creatinine \> 2x or upper limit of normality (KDIGO, 2012)
* Previous severe reaction to a polyene antifungal
* Receipt of more than one dose of a polyene antifungal in the last 48 h
* Suspected histoplasmosis involving the central nervous system
* Patients who, in the judgment of the attending physician, have the prospect of death within the next 48 hours after selection, will also be excluded
* Patients with suspected histoplasmosis involving the central nervous system (CNS), as this condition requires high doses of amphotericin B
* Patients with the prospect of death in the next 48 hours after selection
* Patients with a concomitant diagnosis of cryptococcus will be excluded, as will patients with leishmaniasis in treatment or in secondary prophylaxis with amphotericin
* Patients without the capacity to administer enteral medication-at the discretion of the principal investigator of each center-considering that these patients will not be able to use itraconazole orally or through a feeding tube
