CHMP: Working parties and other groups

The Committee for Medicinal Products for Human Use (CHMP) establishes a number of working parties at the beginning of each three-year mandate. Most working parties operate under the governance of a domain. These working parties have expertise in a particular scientific field, and are composed of members selected from the list of European experts maintained by the Agency.

- to reflect the current structure of working parties and other groups under CHMP

The CHMP consults its working parties on scientific issues relating to their particular field of expertise, and delegates certain tasks to them in the context of the scientific evaluation of marketing authorisation applications or drafting and revision of scientific guidance documents.

Working parties can be supported by operational expert groups (OEGs), temporary drafting groups (tDGs) and European specialised expert communities (ESECs).
