The European Centre for the Validation of Alternative Methods (ECVAM) has restructured its services by directly targeting the animal tests that need to be replaced. In view of the short time-lines for making available and implementing validated methods, ECVAM is offering to steer the process by bringing together the inputs of stakeholders and encouraging the early involvement of regulators. In essence, steering groups formed by ECVAM senior staff, and complemented with external experts, will carry out the project management and will coordinate the various inputs.
