Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Onchocerciasis or river blindness is an infectious disease caused by a parasitic worm. It spreads through the bite of an infected blackfly. Common symptoms include severe itching, skin problems, and eye problems including permanent blindness.

Soil-transmitted helminthiasis is an infection caused by various parasitic worms, such as whipworm, hookworm, and roundworm in the intestines. The infection spreads through eggs found in the feces of infected people. This contaminates the soil in areas with poor sanitation. Common symptoms include stomach pain, loose stools, loss of blood and proteins, delayed development in children, and reduced work performance in adults.

Researchers are looking for better ways to treat onchocerciasis and soil-transmitted helminthiasis. Emodepside is being tested for the treatment of onchocerciasis and soil-transmitted helminthiasis in both men and women. It works by activating a protein called 'SLO-1', which causes paralysis and death of the parasitic worms.

The main purpose of this study is to find out if there is a difference in how emodepside gets absorbed in the blood when given as a new tablet compared to the existing tablet, as a single dose. Researchers also want to find the effect of food on the absorption of the new emodepside tablet.

The amount of emodepside in participants' blood will be measured at various time points. These will be used to calculate and compare the following measurements after a single dose of the new and existing tablet of emodepside without food.

The amount of emodepside in participants' blood will be measured at various time points. These will be used to calculate the Cmax and AUC after a single dose of the new tablet of emodepside with and without food. The number of participants who experience medical problems during this study will be documented.

During this study, participants will receive 2 different types of emodepside tablets. These include the newly developed tablet and an existing tablet that has already been used in other clinical studies.

At the start of the study, the researchers will ask participants about their medical and surgical history. They will also perform a health check-up for all participants, and pregnancy tests for women.

During the study, participants will have blood and urine samples taken to check for any medical problems and to measure the amount of emodepside in the blood.

The study doctors will confirm that the participants can take part in the study. This may take up to 21 days.

This study has 3 or 4 periods and contains up to 2 in-house periods of 16 days each.

On Day 1 of each period, participants will receive the treatments, but the order of the treatment will be different.

• Periods 1 and 2: Each participant will receive a single oral dose of the new or the existing emodepside tablet without food.

After Period 2, an initial analysis will be performed. This analysis will help decide the doses for the next periods.

* Period 3: Participants will receive a selected dose of the new emodepside tablet either with or without food.
* Period 4 (optional): If needed, participants may receive a selected dose of the new emodepside tablet either with or without food. The decisions to conduct Period 4 will depend on the results of the initial analysis.

Participants will have a total of 6 additional weekly visits to the study site for sample collection after the last period (either Period 3 or 4).

Participants will attend a follow-up visit to the study site 49 days after taking their last dose for a health check-up.

This study will include participants who are healthy and will gain no benefit from taking emodepside. However, the results of the study will provide useful information to support the further development of the new emodepside tablet. The results will also provide information on the emodepside doses to be used in patients who need treatment with emodepside. Participants will be closely monitored by the study doctors for any medical problems.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

The study will be conducted in a single-center, randomized, open label, cross over design.

The study will investigate the relative bioavailability, pharmacokinetics, safety and tolerability of single doses of 2 formulations of emodepside and assess the effect of food on Test formulation (Formulation B) in healthy male participants and healthy female participants of non-childbearing potential.

The crossover design is used for intra-individual comparison of treatment effects to reduce impact of inter-individual variability. A preliminary PK analysis is planned after Period 2 to determine the appropriate dose to be tested for food effect.

Treatment allocation is conducted in a randomized manner prior to Period 1 in order to reduce the likelihood of period or seasonal effects confounding the study assessments.
