Trial Type Trial ID Title Status Sponsor Phase Start Date Summary
New Dosage NCT00421187 ↗ Ambisome and Management of Culture-negative Neutropenic Fever Unresponsive to Antibiotics Terminated Gilead Sciences Phase 4 2007-03-01 Administration of a single high dose (10 mg/kg) of AmBisome® no later than 72 hours after ARNF onset followed by two 5 mg/kg doses on days 2 and 5 may provide sustained tissue levels of amphotericin B that are as mycologically effective as those provided after administering the standard daily dose of 3 mg/kg/day. The new dosing regimen is anticipated to be equally clinically effective compared with the standard AmBisome® regimen when given for the duration of neutropenic fever in patients with ARNF. In addition, the degree and incidence of nephrotoxicity are predicted to be lower with the 3 sequential dose regimen compared to daily dosing with 3 mg/kg because of the lower cumulative dosage (20 mg/kg versus 42 mg/kg, respectively), which is 1 contributing factor for the development of acute renal failure. Furthermore, the lower cumulative dose may be a cost-effective strategy for the treatment of patients with ARNF.

NCT00000677 ↗ SCH 39304 as Therapy for Acute Cryptococcal Meningitis in HIV-Infected Patients Followed by Maintenance Therapy Completed Schering-Plough Phase 1 1969-12-31 To assess the safety and effectiveness of SCH 39304 as primary treatment of acute cryptococcal meningitis in HIV-infected patients. Safety and effectiveness of maintenance therapy following successful treatment of acute disease are also evaluated. Cryptococcal meningitis is a significant cause of illness and death in HIV-infected patients. Intravenous amphotericin B is effective for acute disease but relapse occurs in the majority of patients. Maintenance therapy is recommended but must be balanced against the multiple toxicities of the drugs used and the problems associated with the weekly administration of intravenous therapy. Treatments that are equally or more effective and less toxic than traditional methods are needed, especially oral therapy. SCH 39304 is an orally active antifungal drug that in animal studies is active against a wide range of systemic fungal infections including infections due to Cryptococcus. Features of SCH 39304 suggest that it might be of value in the treatment of cryptococcal meningitis.

Amphotericin B: Clinical Trials, Market Analysis, and Projections

Last updated: January 1, 2025

Introduction

Amphotericin B is a potent antifungal medication used to treat a variety of fungal infections, including those caused by Aspergillus, Candida, and Cryptococcus species. This article will delve into recent clinical trials, market analysis, and future projections for this critical drug.

Recent Clinical Trials

AMBITION-cm Trial

One of the most significant recent trials is the AMBITION-cm trial, conducted in 2022. This trial compared a single high-dose regimen of liposomal amphotericin B (10 mg/kg) plus daily flucytosine and fluconazole for 2 weeks against the traditional WHO-recommended regimen of amphotericin B deoxycholate with flucytosine for 1 week, followed by fluconazole for 1 week. The results showed that the single-dose liposomal amphotericin B regimen was noninferior to the traditional regimen, making it a preferred option for HIV-related cryptococcal meningitis[1].

Adoption and Barriers

Despite the promising results, the adoption of the AMBITION-cm regimen in high-resource settings has been slow. A survey of physicians revealed that only about 14% had used this regimen, with the majority citing concerns about the applicability of trials conducted in low-resource settings and the lack of recommendation in older guidelines[1].

Other Formulations

Research is also ongoing into new formulations of amphotericin B to reduce toxicity and improve efficacy. For example, MAT2203, an oral lipid nanocrystal formulation of amphotericin B, has shown promising results in treating deep tissue infections with lower toxicity compared to traditional intravenous formulations[5].
