Efficacy Working Party

The Efficacy Working Party (EWP-V) provides recommendations to the Committee for Veterinary Medicinal Products (CVMP) on all matters relating to the efficacy of veterinary medicinal products, including target-animal safety.

Responsibilities and composition

The group is involved in activities such as preparing and updating European and international guidelines, and providing scientific advice on general and product-specific matters, at the request of the CVMP.

It also addresses queries from other EMA committees, working parties, the European Union (EU) Member States and other parties, and contributes to workshops and training sessions on efficacy assessment for veterinary medicines.

In 2022, the group is focusing on developing and revising guidance documents to support implementation of the European Union (EU) Veterinary Medicines Regulation. For more information on these activities see:

The EWP-V is composed of European experts nominated and appointed by CVMP. Additional observers may also attend the meetings of the working party, if required.

More information on the EWP-V's responsibilities, composition and procedures is available in the following document:
