Frequently asked questions about EDP-978

What is EDP-978 used for?

EDP-978 is an investigational small molecule being developed for chronic inducible urticaria, a type of chronic hives triggered by specific physical stimuli. It is also being studied in chronic spontaneous urticaria. The drug is currently in Phase 1 clinical development and is not yet approved by regulatory authorities.

What does EDP-978 target?

EDP-978 targets KIT, a receptor tyrosine kinase involved in the activation and survival of mast cells. By inhibiting KIT, EDP-978 aims to reduce mast cell activity, which is central to the development of urticaria symptoms. This mechanism is being evaluated in early-stage clinical trials.

Who is developing EDP-978?

EDP-978 is being developed by Enanta Pharmaceuticals, Inc., a biopharmaceutical company traded on NASDAQ under the ticker symbol ENTA. The company is conducting clinical trials to evaluate the safety and efficacy of EDP-978 for chronic urticaria indications.

What phase is EDP-978 in?

EDP-978 is in Phase 1 clinical development. The drug is investigational and has not received regulatory approval. It is currently being studied in a Phase 1 trial that is recruiting participants in the United States to assess its safety, tolerability, pharmacokinetics, and pharmacodynamics.

What clinical trials is EDP-978 in?

EDP-978 is being studied in a Phase 1 clinical trial with the identifier NCT07540910. This randomized, double-blind, placebo-controlled study is investigating the safety, tolerability, pharmacokinetics, and pharmacodynamics of single and multiple doses of EDP-978 in healthy adults. The trial is recruiting participants in the United States.

Is EDP-978 the same as any other drug?

No alternative names for EDP-978 have been disclosed. The drug is identified solely by its development code EDP-978 and is being investigated by Enanta Pharmaceuticals for chronic urticaria conditions. It is a distinct small molecule candidate in early clinical development.
