Topical Sm29 in Combination With Meglumine Antimoniate in the Treatment of Cutaneous Leishmaniasis.

August 17, 2023 updated by: Paulo Roberto Lima Machado, Hospital Universitário Professor Edgard Santos

Association of Topical Sm29 in Gold Nanoparticles With Intravenous Meglumine Antimoniate in the Treatment of Cutaneous Leishmaniasis Caused by Leishmania Braziliensis: A Randomized Controlled Trial.

This project is composed of a phase I study with the purpose of evaluating adverse reactions and the best dose to be used of Sm29 and a phase II randomized controlled study with 3 arms with the purpose of comparing the efficacy of meglumine antimoniate associated with Sm29, with meglumine antimoniate plus placebo and meglumine antimoniate alone in the treatment of cutaneous leishmaniasis.

Detailed Description

The phase I study was performed in 10 healthy subjects and 10 patients with CL. In healthy individuals (N=5) Sm29 was applied to healthy skin at a concentration of 5ug and in another 5 Sm29 was used at a dose of 10ug applied twice a day for 20 days. A phase I study was also carried out in 10 patients with CL to assess the occurrence of adverse reactions to Sm29 applied to the ulcerated lesion and to compare the use of two doses of Sm29. In 5 patients, Sm29 was used at a dose of 5ug and applied twice a day, and in 10 patients, a dose of 10ug of Sm29 was used, also applied twice a day. The 10 patients were also treated with glucantime at a dose of 20mg/kg/weight with a maximum dose of 1200mg/day intravenously for 20 days. Patients were evaluated on days 10, 20 and 30 for adverse reactions.
