Safety and Efficacy Study of Paromomycin to Treat Visceral Leishmaniasis

Phase 3

Completed

• Conditions: Visceral Leishmaniasis

• Registration Number: NCT00216346
• Lead Sponsor: PATH

Brief Summary

Symptomatic Visceral Leishmaniasis(VL)is fatal; Due to the increasing resistance to standard therapy with antimonials, there is a need for new safe, efficacious, low-cost therapies for the treatment of VL. Paromomycin is an off-patent aminoglycoside antibiotic with anti-leishmaniasis activity. This study will test the safety and efficacy of paromomycin in the treatment of patients with VL in India.
