Abstract
Background: Meglumine antimoniate (MA) remains the main treatment for cutaneous leishmaniasis (CL), despite its high toxicity. Uncontrolled studies suggest that intralesional infiltration of MA (IL-MA) may be non-inferior in efficacy and safer than systemic (S-MA).
Methods: Multicenter, randomized, controlled, open-label, phase III clinical trial to evaluate the efficacy and toxicity of IL-MA in 3 infiltrations at 14-day intervals compared to S-MA (10 to 20 mg Sb5+/kg/day, 20 days) for CL. Primary and secondary outcomes were respectively definitive cure at day 180 and epithelialization rate at day 90 of treatment. A non-inferiority margin of 20% was used to estimate the minimum sample. A two-year follow-up was performed to assess relapses and emergence of mucosal lesions. Adverse events (AE) were monitored according to The DAIDS AE Grading.
Results: This study evaluated 135 patients. The cure rates (confidence interval 95%) of IL-MA and S-MA treatment were respectively 82.8% (70.5-91.4) and 67.8% (53.3-78.3) per protocol (PP), and 70.6% (58.3-81.0) and 59.7% (47.0-71.5) per intention to treat (ITT). The epithelialization rates of the IL-MA and S-MA treatment were respectively 79.3% (66.6-88 + 8) and 71.2% (57.9-82.2) PP, and 69.1% (55.2-78.5) and 64.2% (50.0-74.2) ITT. AE in IL-MA and S-MA groups were respectively: clinical 45.6%, 80.6%; laboratory 26.5%, 73.1%; EKG 8.8%, 25.4%. Ten participants in the S-MA and one in the IL-MA group were discontinued due to severe or persistent AEs.
Conclusion: IL-MA provides similar cure rate and results in less toxicity compared to S-MA in CL patients. IL-MA may be used as first line therapy for CL.
