History of Changes
  Purpose

This is a phase II/III open, comparative dose trial to find the lowest single dose of AmBisome for the treatment of primary, symptomatic visceral leishmaniasis(VL), in HIV negative patients. In this trial, the minimum effective dose will be determined in a sequential step, dose escalation design, which minimises the number of patients exposed to low, potentially inadequate doses and provides contemporaneous comparative data against the manufacturer's recommended dose schedule in this indication.

Primary Outcome Measures:
  • The primary efficacy variable is parasitological clearance with no relapse at 6 months post treatment (ie definitive cure) assessed by clinical status and confirmed by splenic or bone marrow aspiration. [ Time Frame: at 6 months post treatment ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Parasitological clearance at day 30. [ Time Frame: Day 30 ] [ Designated as safety issue: No ]

Estimated Enrollment: 240
Study Start Date: April 2009
Estimated Study Completion Date: June 2011
Estimated Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
