Frequently asked questions about emodepside

What is emodepside used for?

Emodepside is being developed for the treatment of soil-transmitted helminth infections, including Trichuris trichiura (whipworm), hookworm infection, and Ascaris lumbricoides (roundworm) infection. It is an investigational small molecule in Phase 3 clinical development and is not yet approved for these infections.

Who is developing emodepside?

Emodepside is being developed by Bayer AG, which trades on the OTC market under the ticker BAYRY. Bayer is running the Phase 3 clinical program evaluating the drug in participants with soil-transmitted helminth infections across multiple countries.

What phase is emodepside in?

Emodepside is in Phase 3 clinical development. Two Phase 3 trials are ongoing, one active and not recruiting and one not yet recruiting, with a combined planned enrollment of 630 participants. The drug is investigational and has not been approved for any indication.

What clinical trials is emodepside in?

Emodepside is being studied in two Phase 3 trials: NCT06800248, which is not yet recruiting in the Philippines, and NCT06736691, which is active and not recruiting in Tanzania. Both trials enroll participants aged 12 years and older with soil-transmitted helminth infections and each plans to enroll 315 participants.

Is emodepside the same as BAY 44-4400?

Yes, emodepside is also known as BAY 44-4400. Both names refer to the same investigational small molecule developed by Bayer AG for soil-transmitted helminth infections, including Trichuris trichiura, hookworm, and Ascaris lumbricoides infections.

How is emodepside studied in its Phase 3 trials?

Both Phase 3 trials of emodepside are randomized, double-blind, and active-controlled, enrolling 315 participants each. They include participants aged 12 years and older with Trichuris trichiura, hookworm, or Ascaris lumbricoides infection, and neither trial selects patients by biomarker.
