Abstract:
Lymphatic filariasis and onchocerciasis are neglected tropical diseases (NTDs) targeted for elimination by mass (antifilarial) drug administration. These drugs are predominantly active against the microfilarial progeny of adult worms. New drugs or combinations are needed to improve patient therapy and to enhance the effectiveness of interventions in persistent hotspots of transmission. Several therapies and regimens are currently in (pre-)clinical testing. Clinical trial simulators (CTSs) project patient outcomes to inform the design of clinical trials but have not been widely applied to NTDs, where their resource-saving payoffs could be highly beneficial. We demonstrate the utility of CTSs using our individual-based onchocerciasis transmission model (EPIONCHO-IBM) that projects trial outcomes of a hypothetical macrofilaricidal drug. We identify key design decisions that influence the power of clinical trials, including participant eligibility criteria and post-treatment follow-up times for measuring infection indicators. We discuss how CTSs help to inform target product profiles.
Insights
Clinical trial simulators can optimize the design of studies for neglected tropical diseases like lymphatic filariasis and onchocerciasis. This approach helps improve drug development and intervention strategies for these widespread infections.
Area of Science:
- Tropical medicine
- Parasitology
- Computational biology
Background:
- Lymphatic filariasis and onchocerciasis are neglected tropical diseases (NTDs) targeted for elimination through mass drug administration.
- Current antifilarial drugs primarily target microfilariae, necessitating new therapies for persistent transmission hotspots.
- Clinical trial simulators (CTSs) offer potential benefits for NTD research but are underutilized.
Purpose of the Study:
- To demonstrate the utility of CTSs in designing clinical trials for NTDs.
- To project the outcomes of a hypothetical macrofilaricidal drug for onchocerciasis.
- To inform target product profiles and optimize intervention strategies.
Main Methods:
- Utilized an individual-based onchocerciasis transmission model (EPIONCHO-IBM) as a CTS.
- Simulated clinical trial outcomes for a hypothetical macrofilaricidal drug.
- Analyzed the impact of key trial design parameters on study power.
Main Results:
- Identified critical trial design decisions influencing study power, such as participant eligibility and follow-up duration.
- Demonstrated that CTSs can effectively project patient outcomes for antifilarial drug trials.
- Highlighted the role of CTSs in refining target product profiles for new NTD therapies.
Conclusions:
- CTSs are valuable tools for optimizing clinical trial design in neglected tropical diseases.
- Simulation-based approaches can enhance the efficiency and effectiveness of drug development for lymphatic filariasis and onchocerciasis.
- Informing trial design through CTSs can accelerate progress towards the elimination of these NTDs.
