About this trial

The purpose of this clinical trial is to compare the efficacy and safety of emodepside with the standard treatment, albendazole, in adolescents (12 years and older) and adults infected with Trichuris incognita.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Aged 12 years and above.

Written informed consent signed by participant and, in the case of minors, parents/caregivers.

Agree to comply with study procedures, including provision of two stool samples at the beginning (screening) and at follow-up assessment 14-21 days after treatment.

Having at least two slides of the quadruple Kato-Katz thick smears positive for Trichuris incognita and infection intensities of at least 48 eggs per gram (EPG).

Disqualifiers

Presence or signs of major systemic illnesses, e.g. body temperature ≥ 38 °C, severe anemia (Hb below 80g/l) upon initial clinical assessment etc.

History of severe acute or unmanaged severe chronic disease (i.e., condition is not as therapeutically controlled as necessary).

Positive malaria rapid diagnostic test (RDT) and temperature ≥ 38 °C.

Abnormal liver and renal function assessed by biochemical blood-based analyses.

Trial outcomes

Primary outcomes

1

Cure rate (CR) of emodepside compared to albendazole against Trichuris incognita

Trichuris incognita infection status of participants 14-21 days post-treatment assessed by Kato-Katz. CRs will be calculated as the percentage of egg-positive participants at screening who become egg-negative after treatment, for each treatment arm. Differences in CRs between the two treatments will be assessed.

Time frame
Between 14-21 days post-treatment

Secondary outcomes

1

Egg-reduction rate (ERR) of emodepside compared to albendazole against Trichuris incognita

Eggs per gram of stool (EPG) will be assessed by adding up the egg counts from the quadruplicate Kato-Katz thick smears and multiplying this number by a factor of six. Geometric mean egg counts will be calculated for the different treatment arms before and after treatment to assess the corresponding ERRs. ERR is caluclated as follows: ERR = (1- (geometric mean EPG at follow-up ÷ geometric mean EPG at baseline)) x 100

Time frame
Between 14-21 days post-treatment
2

Safety and tolerability

Tolerability of treatments (adverse events (AEs)) will be assessed at 3- and 24- hours post-treatment and at 14 - 21 days follow up. The safety analysis will be conducted on all participants who were treated and include all available drug safety data. AEs will be evaluated descriptively as the difference between proportions of reported AEs before and after treatment.

Time frame
3- and 24- hours post-treatment and retrospectively 14-21 days post-treatment

Other outcomes

1

CR and ERR of emodepside and albendazole against Ascaris lumbricoides and hookworm in co-infected participants

If there are enough co-infections in the sample, exploratory analyses will be performed to assess the difference in cure rates and ERR for hookworm and A. lumbricoides. If there are fewer than 30 participants with co-infections of a certain species in total, the results will only be provided descriptively.

Time frame
Between 14-21 days post-treatment
