Study Details

Study Description

Brief Summary

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.

Condition or Disease Intervention/Treatment Phase
  • Drug: Sm29 Protein, Schistosoma Mansoni
  • Drug: Pentavalent antimony (Sbv)
Phase 1/Phase 2

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.
