Summary
Taenia solium neurocysticercosis (NCC) is a parasitic infection causing much neurological disease in most of the world. When parasites locate in the cavities around the brain (subarachnoid NCC, SANCC), it becomes an aggressive, progressive and frequently lethal presentation. Current treatment regimens for SANCC have quite limited efficacy. The investigators propose to compare the current standard of care (a single antiparasitic drug, albendazole) with a combined regimen using two antiparasitic drugs simultaneously by adding praziquantel. The trial will enrol 164 patients in four centers, two in Peru, one in Ecuador, and one in Brasil.
Description
Double-blind, randomized, placebo-controlled study in patients with subarachnoid cysticercosis of the basal cisterns or the Sylvian fissure, comparing in two parallel arms the efficacy of the standard of care anti-parasitic regime (30 days of ABZ at 15 mg/k/d, up to 1200 mg/k/d) with a combined regime using similar doses of ABZ and adding PZQ at 50 mg/k/d for the initial 15 days of anti-parasitic treatment. The study and interim analysis plan are designed to allow direct, concrete efficacy comparison in this deadly type of NCC while minimizing the risks of disease progression in the standard of care arm.
In short, this is a parallel group study with a dichotomous primary outcome variable. The main analysis will compare the proportions of patients obtaining the primary outcome at 6 months, using a Chi-square test in a bivariate analysis. A similar analysis will be used for the proportions of patients with a good clinical outcome, and the proportions of patients in whom lesion resolution sustains when assessed at month 12. A Student T test analysis will be used to compare for reduction in parasite volume and non-parametric Mann-Whitney test will be alternatively applied for non-normally distributed data. A non-parametric Spearman's Rho test will be used to assess the correlation between the proportions of cyst mass reduction with the decrease in antigen levels in each study group. A Chi-square test in a bivariate analysis will evaluate the association between negative antigen levels at 6 months versus the complete disappearance of cyst mass.
