Assessment of Combined Praziquantel and Albendazole vs Albendazole Alone to Treat Active Parenchymal Neurocysticercosis

Overview

The goal of this clinical trial is to compare the combination albendazole and praziquantel versus albendazole alone in patients affected by neurocysticercosis.

This is a randomized, two arms, parallel-groups, open-label clinical trial to assess if the combination of antiparasitic praziquantel and albendazole is better than albendazole alone in the treatment of active parenchymal neurocysticercosis in Tanzania and Zambia. Background and Study Rationale: between the forms of human cysticercosis caused by Taenia solium, neurocysticercosis is a major contributor to the burden of seizure disorders and epilepsy in most of the world, while it has relatively poor clinical evidence on treatment options, requiring further data, mainly from additional randomized controlled trials. In particular albendazole and praziquantel are the two parasiticides recommended for use in treating active neurocysticercosis (NCC). Specifically, albendazole is recommended for use in patients with a single cyst while both albendazole and praziquantel (combination therapy) are recommended for patients with multiple cysts. However, not all patients with single cysts respond to albendazole monotherapy. Combination therapy may be effective in patients with single cysts as it has already been shown effective for multiple cysts. Most studies of treatment success for NCC have been conducted in Latin America and India. In India, the studies were performed primarily on singular cystic lesions. Despite Sub-Saharan Africa (SSA) being recognized as endemic for this parasite, no study evaluating the success of standard treatment in humans has been conducted in this region. Additionally, it is difficult to extrapolate information from other regions other than SSA due to possible differences in genetic, clinical, and environmental factors. Primary Objective: The primary objective of this study is to determine if the anthelmintics combination of praziquantel and albendazole is better than albendazole alone in the treatment of the active parenchymal neurocysticercosis based on cyst resolution. Secondary Objectives: 1. To determine if the combination of antiparasitic praziquantel and albendazole is better than albendazole alone in the treatment of active parenchymal neurocysticercosis based on seizures reduction 2. To estimate the change in quality of life of patients with active symptomatic NCC before and after treatment with combined antiparasitic treatment and mono… 3. To assess the role of serology in diagnosis, management and follow up of participants treated for neurocysticercosis.
