Filter by:To compare the efficacy and safety of emodepside to that of albendazole (Zentel®) in participants aged 12-60, inclusive, infected with hookworm.
The rationale of the study is to provide evidence on the efficacy and safety of Emodepside in adults infected with Trichuris trichiura and hookworm.
This study is a double-blind randomized controlled superiority trial aiming at providing evidence on the efficacy and safety of co-administered moxidectin and albendazole versus albendazole monotherapy (standard of care) against whipworm (T. trichiura) infections in adolescents and adults (12-60 years) in Côte d'Ivoire. One arm of patients will be treated with albendazole-ivermectin. As measure of efficacy of the treatment the cure rate (percentage of egg-positive subjects at baseline who become egg-negative after treatment) will be determined 14-21 days post-treatment.
The aim of this randomized controlled trial is to provide evidence on the efficacy and safety of co-administered moxidectin and albendazole compared to co-administered ivermectin and albendazole, and to assess the efficacy of the drug combinations compared to monotherapies in adolescents aged 12-19 years against infection with T. trichiura. The efficacy of the different treatments will be determined 14-21 days, 5-6 weeks and 3 months post-treatment. Two fecal samples will be collected at each time-point assessment. The geometric mean based egg reduction rate (ERR) of T. trichiura egg counts will be assessed by Kato-Katz microscopy pre-treatment and 14-21 days post-treatment. This trial will be conducted as a school-based study on Pemba Island (Zanzibar, Tanzania).
The rational of this study is to provide evidence on the safety and efficacy of a new chewable tablet of mebendazole compared to the standard tablet in preschool- and school-aged children infected with hookworm.
24 healthy volunteers will be immunized with three times 50 L3 larvae or placebo followed by treatment with albendazol and subsequently challenged with twice 50 L3 larvae.
This study is a single-blind randomized clinical trial conducted in rural Côte d'Ivoire. This study aims at providing evidence on the dose-response of increasing oral albendazole dosages against whipworm (T. trichiura) and hookworm infections in preschoolers (2-5 years), school-aged children (6-12 years) and adults (≥ 21 years). The primary objective is to determine cure rates (primary end point, i.e. conversion from being egg positive pre-treatment to egg negative post-treatment). Secondary objectives involve the determination of egg reduction rates (the reduction in the number of excreted eggs from baseline (prior to treatment) to follow-up) and the assessment of safety of ascending dosages of albendazole (secondary end points). In addition, key pharmacokinetic parameters will be determined from blood samples collected with a micro-sampling device (secondary end point).
Na-GST-1 is a protein expressed during the adult stage of the Necator americanus hookworm life cycle that is thought to play a role in the parasite's degradation of host hemoglobin for use as an energy source. Vaccination with recombinant Na-GST-1 has protected dogs and hamsters from infection in challenge studies. This study will evaluate the safety and immunogenicity of administering Na-GST-1 with or without the CpG 10104 immunostimulant to healthy Gabonese adults living in an area of endemic hookworm infection.
More than one billion people are infected with soil-transmitted helminths (STH, A. lumbricoides, hookworm or Trichuris trichiura). Preventive chemotherapy - i.e. annual or biannual treatment of at-risk populations with albendazole or mebendazole is the current strategy against STH. However, the efficacy of both drugs is only moderate against hookworm and low against T. trichiura. For increasing the efficacy and to avoid drug resistance, new drugs or the combination of different drugs is the way forward. In this randomised controlled trial, we assess the efficacy (based on cure rates) of different drug combinations in school-aged children in Lao. 420 hookworm positive children will be treated: 140 with albendazole-oxantel pamoate, 140 with albendazole-pyrantel pamoate-oxantel pamoate treatment arms, 70 with pyrantel pamoate-oxantel pamoate and 70 with mebendazole-pyrantel pamoate-oxantel pamoate. Two stool samples will be collected at baseline and follow-up (14-21 days after treatment) and analysed with Kato-Katz.
Twenty-four healthy hookworm-naive volunteers will be exposed to 50 L3 Necator americanus larvae for a maximum of three times.
