Scientific advice and protocol assistance

The European Medicines Agency (EMA) can give scientific advice and protocol assistance to companies involved in developing medicines. For human medicines, scientific advice and protocol assistance are given by the Committee for Medicinal Products for Human Use (CHMP) on the recommendation of the Scientific Advice Working Party (SAWP).

Scientific advice is when the Agency gives advice to a company on the appropriate tests and studies in the development of a medicine. This is designed to facilitate the development and availability of high-quality, effective and acceptably safe medicines, for the benefit of patients.

Companies can request scientific advice from the EMA at any stage of development of a medicine, whether the medicine is eligible for the centralised authorisation procedure or not.

Scientific advice helps the company to make sure that it performs the appropriate tests and studies, so that no major objections regarding the design of the tests are likely to be raised during evaluation of the marketing-authorisation application. Such major objections can significantly delay the marketing of a product, and, in certain cases, may result in refusal of the marketing authorisation. Following the Agency’s advice increases the probability of a positive outcome.

The Agency gives scientific advice by answering questions posed by companies. The advice is given in the light of the current scientific knowledge, based on the documentation provided by the company. It is not the role of the CHMP to substitute the industry's responsibility for the development of their products.

Scientific advice is prospective in nature. It focuses on development strategies rather than pre-evaluation of data to support a marketing-authorisation application.

Scientific advice received from the Agency is not legally binding on the Agency or on the sponsor with regard to any future marketing-authorisation applications for the medicine concerned.

Protocol assistance

Protocol assistance is the special form of scientific advice available for companies developing designated orphan medicines for rare diseases.

In addition to scientific advice, companies developing an orphan medicinal product can receive answers to questions relating to the criteria for authorisation of an orphan medicine. These include:

  • the demonstration of significant benefit within the scope of the designated orphan indication;
  • similarity or clinical superiority over other medicines. This is relevant if other orphan medicinal products exist that might be similar to the product concerned and which have market exclusivity in the same indication.

Requesting scientific advice

Companies can request scientific advice or protocol assistance either during the initial development of a medicinal product before submission of a marketing-authorisation application or later on, during the post-authorisation phase. Scientific advice and protocol assistance are particularly useful to companies developing a medicinal product when:

  • there appears to be no or insufficient relevant detail in European Union guidelines or guidance documents, or in Pharmacopoeia monographs, including draft documents or monographs released for consultation;
  • when the company chooses to deviate from the available guidance in its development plan.

For details on how to apply, see how to submit a scientific-advice or protocol-assistance request.

Scientific advice on post-authorisation safety studies (PASS)

Starting in July 2015, EMA is launching a 12-month pilot to encourage companies to seek scientific advice for PASSs for medicines. This voluntary, optional procedure will help to improve the design of studies meant to collect further information on a medicine's safety once it is on the market. This pilot will build on the expertise of the Agency's Pharmacovigilance Risk Assessment Committee. The main focus of the pilot will be non-imposed PASSs, which are studies that are not a condition to the marketing authorisation.

Parallel scientific advice with the Food and Drug Administration

The Agency provides scientific advice and protocol assistance in parallel with the United States Food and Drug Administration (FDA):

Parallel scientific advice from regulators and HTA bodies

The Agency offers scientific advice in parallel with HTA bodies. This procedure aims to allow medicine developers to gain feedback from regulators and HTA bodies at the same time, at any point in the developmental lifecycle of medicines. This helps them to establish the evidence that both parties will need to determine a medicine's benefit-risk balance and value as efficiently as possible.

Fees and fee reductions

EMA charges a fee for scientific advice, which varies depending on the scope of the advice. Reductions apply for certain types of medicines.

For more information, see fees payable to EMA.
