RESUMEN

A liposomal amphotericin B preparation (L-AMP-LRC-1) has been developed and tested successfully in adults by us. This preparation was administered to 23 neonates with candidiasis in an open phase II study. All the 14 assessable patients responded completely to the L-AMP-LRC-1 therapy given at 1 mg/kg for 28 days. Compared to AmBisome, another liposomal formulation of amphotericin B, L-AMP-LRC-1 was effective at lower dose in neonatal candidiasis. Thus L-AMP-LRC-1 appears to be an effective and low cost drug for the treatment of candidiasis.

RESUMEN

OBJECTIVE: To compare conventional amphotericin B (c-amp B) and liposomal amphotericin B (L-AMP-LRC-1-India) in patients with systemic fungal infection in open, randomized, comparative, laboratory blind, phase III safety and efficacy study. MATERIAL AND METHODS: Formulation of liposomal amphotericin B - L-AMP-LRC-1, containing natural phospholipids, was prepared and tested at the Department of Clinical Pharmacology, Seth GS Medical College and KEM Hospital, Mumbai, India. Patients suffering from proven systemic fungal infection, were treated with c-amp B or L-AMP-LRC-1 with 17 patients in each group. Data was compared for the safety and efficacy. RESULTS: Safety: L-AMP-LRC-1 was better tolerated than c-amp B. Out of the 695 infusions of c-amp B fever occurred on 25.04% occasions in 68.42% patients, while it occurred on 2.09% occasions out of 767 infusions (in 30.43% patients of L-AMP-LRC-1. Chills occurred on 16.83% and 1.17% occasions after c-amp B and liposomal amphotericin B respectively. Other adverse effects observed on 0.2-5% of occasions were: headache, nausea, vomiting, palpitation and dizziness occurring more frequently in c-amp B group. The L-AMP-LRC-1 did not cause bronchospasm at 1 mg/kg dose in a patient who developed bronchospasm to 0.1 mg/kg dose of c-amp B. The L-AMP-LRC-1 was found to be less nephrotoxic than c-amp B and could be administered to patients who had renal problems or had undergone renal transplant. L-AMP-LRC-1 caused less hypokalemia than c-amp B. Effficacy: 17/17 patients in L-AMP-LRC-1 group and 14/17 in c-amp B group had complete response (100% and 82.35% response rate). The number of infusions and dose of amphotericin B and L-AMP-LRC-1 used were similar and required individualization of duration of treatment (in cases where response to fixed duration was not observed). All the patients were treated with 0.5 to 1.0 mg/kg/day dose of L-AMP-LRC-1 (except one patient required 2 mg/kg dose). This is markedly different from other marketed liposome and lipid formulations, which are recommended at higher (3-5 mg/kg) doses every day. At the same time L-AMP-LRC-1 being prepared from naturally occurring lipids is expected to cost at least one-third of the marketed formulation. Thus cost of every day treatment would be very much less compared to other delivery systems. Thus L-AMP-LRC-1 will be an economical and safe treatment option available to the physicians for the treatment of systemic fungal infection.

RESUMEN

Four patients with cryptococcal meningitis were successfully treated with liposomal amphotericin B prepared at our institute using Soya phosphatidylcholine and cholesterol. In one patient, response with 1 mg/kg/day treatment was poor. However, on increasing the dose to 2 mg/kg/day, a good response was observed with CSF becoming negative for Cryptococcus neoformans after seven days of this enhanced dose. L-AMP-LRC-1 was found to be well tolerated and a major advantage was observed in two renal transplant patients in whom it could be given safely.
