Clinical Trial: Efficacy of Topical Liposomal Form of Drugs in Cutaneous Leishmaniasis
Study Status: Completed
Recruit Status: Completed
Study Type: Interventional
Official Title: Pilot Study of Efficacy of Topical Nano-liposomal Meglumine Antimoniate (Glucantime) or Paromomycin in Combination With Systemic Glucantime for the Treatment of Anthroponotic Cut
Brief Summary:
Leishmaniasis with diverse clinical manifestations is caused by different species of Leishmania and is endemic in many countries. Although Cutaneous Leishmaniasis (CL) is a self-healing disease, but it takes a long time to heal. Pentavalent antimonials are still the first-line treatment of CL which needs multiple injections, are painful and as such not tolerated by most of the patients, in addition available treatments are not always effective and resistance is reported. Paromomycin sulfate (PM) reported to show anti-Leishmania activity against both CL and visceral leishmaniasis (VL) since 1960s. Therapeutic strategy with high efficacy is urgently needed especially for Anthroponotic Cutaneous Leishmaniasis (ACL). Liposomes are lipid bilayer molecules which entrap water-soluble molecules in their internal water compartment and water-insoluble ones into their lipid bilayers. Liposomes, in proper formulations and sizes, deliver drugs to the skin based on the similarity of the bilayers structure of lipid vesicles to that of natural membrane and target the macrophages within dermis. Several lipid-based formulations have been developed to treat experimental leishmaniasis. Recently different doses of liposomal formulation of PM and liposomal formulation of Glucantime were prepared and showed high efficacy in vivo against L. major infection in BALB/c mice.
In this study the efficacy of liposomal formulation of PM or liposomal formulation of Glucantime in combination with systemic Glucantime in the treatment of ACL parasitologically proven patients will be evaluated. The clinical trial will be carried out according to the International approved GCP (Good Clinical Practice) guide lines.
