Data exclusivity for medicinal products in Europe...8+2+1 approach

Data exclusivity for medicinal products in Europe

The pharmaceutical sector is heavily regulated, with significant costs associated with both developing a new medicinal product and generating the data required to get a product to market. Protecting that data is therefore important.  Data exclusivity is a form of product exclusivity right for medicinal products in Europe, and market exclusivity is a related form of additional protection.
These two rights are in addition to any granted patent exclusivity right covering a medicinal product.

Why is data exclusivity granted?

The rationale for granting data and market exclusivity is to compensate the innovator company for the investment it has put in to developing the new medicinal product and to generating the data required to obtain a marketing authorisation.

Regulatory approval for medicinal products requires applicants to provide information about the efficacy and safety of their product to regulatory authorities. The first applicant for approval of a new medicinal product must provide a substantial body of data relating to the product (including the results of pre-clinical tests and clinical trials).
The regulatory regime permits generic companies, who subsequently wish to gain their own approval for the same drug substance, to rely on information filed by the innovator company that made the first application.  In order to be able to benefit from the data provided by the innovator in their regulatory filings for that medicinal product - the "reference medicinal product" - a generic company must show that their product has the same qualitative and quantitative composition as that product and that it is bioequivalent.

So what is the impact of a product enjoying "data exclusivity"?

An innovator company enjoys a period of "data exclusivity" during which their pre-clinical and clinical trials data may not be referenced in the regulatory filings of another company(typically a generic company) for the same drug substance
For marketing authorisation applications made from November 2005 onwards, the period of data exclusivity in Europe has been harmonised as 8 years from the date of first authorisation in Europe.  For marketing authorisation applications made before November 2005, the period of data exclusivity varies from EU member state to EU member state, and is either 6 years or 10 years.
For marketing authorisation applications made from November 2005 onwards, there is an additional period of 2 years of "market exclusivity".  This is the period of time during which a generic company may not market an equivalent generic version of the originator's pharmaceutical product (although their application for authorisation may be processed during this period, such that they are in a position to market their product on the expiry of this additional 2 year period).

An extra year of protection for new indications

As noted above, the rules determining exclusivity changed in 2005. Under the "old rules" data exclusivity lasted either 6 or 10 years. The "new rules" follow an "8 + 2 + 1" year approach:

"Under the 'old rules' data exclusivity lasted up to 10 years. The 'new rules' follow an '8 + 2 + 1' year approach."
  • During the first 8 years from the grant of the innovator company's marketing authorisation, data exclusivity applies.
  • After the 8 years have expired a generic company can make use of the pre-clinical and clinical trial data of the originator in their regulatory applications, but still cannot market their product.
  • After a period of 10 years from the grant of the innovator company's marketing authorisation, the generic company can also market their product, unless the innovator product qualifies for a further one year of exclusivity. 
  • This additional 1 year may be obtained in a number of circumstances, such as where the innovator company is granted a marketing authorisation for a significant new indication for the relevant medicinal product. In such a situation the generic company can only market their product after 11 years from the grant of the innovator company's marketing authorisation.

How to Calculate Data Exclusivity Periods in Europe 

An application for approval of a New Chemical Entity must contain data to allow assessment of the safety and efficacy profile. These data include pharmacological and toxicological tests and the results of clinical trials. 
To avoid repeating such tests and trials, applications for generic pharmaceutical substances are not required to include these data; instead they may rely on the data provided in relation to the NCE application. However, EC directive 2001/83/EC prevents regulatory authorities from accepting applications for approval of generics that rely on this data until a data exclusivity period has expired. 

This period starts on the day of the first marketing authorisation in the European Community (including Liechtenstein/Switzerland), and expires either six or ten years thereafter, depending on the country in which the application is to be filed and the procedure used to file it. 

Data exclusivity relates to the active ingredient per se, new periods of data exclusivity are not applied to later approval of new dosage forms, routes of administration or indications. 1) To calculate the expiry of the data exclusivity period for centralised applications add 10 years to the corresponding European First Marketing Authorisation Date shown in the Pipeline Selector Report. 2) To calculate the expiry of the data exclusivity period for national or mutual recognition procedure applications, add the term from the following table to the corresponding European First Marketing Authorisation

* Poland has a data exclusivity period of 3 years for approvals prior to 1/5/2004 and 6 years thereafter. Hungary, Slovenia, Slovakia and Malta have requested transitional data exclusivity periods. 

New Data Exclusivity Provisions for Europe A New Data protection directive (2004/27/EC) has been introduced in Europe, which provides eight years of protection from the first European Community marketing authorisation date, after which a European regulatory body may accept an application for approval of a generic. However, the product may not be marketed within ten years of the first European Community marketing authorisation date. An additional one year period of data exclusivity is allowed in respect of new indications with ‘significant clinical benefit’ over the existing indications. Approvals for other product line extensions, including different pharmaceutical forms, are regarded as a bundle of approvals for which only one data exclusivity period is available. This new directive applies only to data relating to NCE products submitted for approval after 31 October 2005, hence do not affect any of the current Pipeline Patent Intelligence products. 

Generic applications in the EU, patents and exclusivity

Types of protection on the originator molecule that have to be taken into account by generic drug manufacturers when filing applications for generic drugs in the EU include the following:
  • patents at the time of marketing
  • supplementary protection certificates at the time of marketing
  • data/regulatory exclusivity at the time of regulatory submission
  • market exclusivity at the time of marketing.
Patents in the EU last for 20 years. Pharmaceutical products are normally covered by a number of patents, sometimes by as many as 30 to 40 patents or more. For pharmaceuticals these patents can be extended with a maximum of five years via a supplementary protection certificate.
A patent on a new use or ‘indication’, formulation, salt or ester can block the registration or marketing of a generic medicine for treatments where the original patent has already expired. This strategy is known as ‘evergreening’ aims to prevent or delay competition from generic medicines by extending market protection through patents on minor changes to the original product.
Data exclusivity
Data exclusivity is a separate and additional provision to patent protection for the originator medicine. With data exclusivity, there can be neither disclosure of regulatory data to a competitor nor regulatory reliance upon the data. Data exclusivity is the period during which no generic drug application can take place.
Therefore, generic medicines can only be evaluated and approved by the medicines regulatory authorities after the data exclusivity period has expired.
In the EU there is now an 8+2(+1) formula for data and marketing exclusivity, which means that originator's data is protected for 8 years and they have marketing exclusivity for a maximum of 11 years from first marketing approval in the EU.
Exclusivity period: 8+2(+1)
The 8+2(+1) exclusivity period came into effect in the EU in late 2005.
8 years data exclusivity dating from the European Commission authorisation decision: before that, no generic applications may be filed.
+2 years marketing protection: no generic applications may be approved.
+1 year: new indication(s) if it constitutes a significant clinical benefit.
It applies for all products, regardless of whether they followed a centralised or national approval procedure.
It is not retroactive; it does not affect exclusivity periods for products for which applications were submitted before the effective date—late 2005.
Market exclusivity
With marketing exclusivity, the agency cannot allow a competing product to enter the market during the time period in which an innovator has a right of exclusivity.
Submission of generic applications is only possible after the expiry of the data exclusivity at year 8. However, there is no linkage of patent protection with registration. Approval of the application and launch of the generic can then take place at year 10 if there is no patent protection, and if there is no additional 1 year of marketing exclusivity due to a significant new indication registered for the reference product during the first 8 years of license, see figure below.

Marketing Authorisation in Europe

European Commission logoAuthorisation Procedures for medicinal products

Procedures for evaluating medicinal products and granting marketing authorisation

The European system for the authorisation of medicinal products for human and animal use was introduced in January 1995 with the objective of ensuring that safe, effective and high quality medicines could quickly be made available to citizens across the European Union.
The European system offers several routes for the authorisation of medicinal products:
  • The centralised procedure, which is compulsory for products derived from biotechnology, for orphan medicinal products and for medicinal products for human use which contain an active substance authorised in the Community after 20 May 2004 (date of entry into force of Regulation (EC) No 726/2004) and which are intended for the treatment of AIDS, cancer, neurodegenerative disorders or diabetes. The centralised procedure is also mandatory for veterinary medicinal products intended primarily for use as performance enhancers in order to promote growth or to increase yields from treated animals.
    Applications for the centralised procedure are made directly to the European Medicines Agency (EMA) and lead to the granting of a European marketing authorisation by the Commission which is binding in all Member States.
  • The mutual recognition procedure, which is applicable to the majority of conventional medicinal products, is based on the principle of recognition of an already existing national marketing authorisation by one or more Member States.
  • The decentralised procedure, which was introduced with the legislative review of 2004, is also applicable to the majority of conventional medicinal products. Through this procedure an application for the marketing authorisation of a medicinal product is submitted simultaneously in several Member States, one of them being chosen as the "Reference Member State". At the end of the procedure national marketing authorisations are granted in the reference and in the concerned Member States.
Purely national authorisations are still available for medicinal products to be marketed in one Member State only.
Special rules exist for the authorisation of medicinal products for paediatric use, orphan drugs, traditional herbal medicinal products, vaccines and clinical trials.

The EMA and the authorisation procedure

In 1993 the European Medicines Agency (EMA) was founded with the primary task of providing scientific advice of the highest possible quality to the Community Institutions on all matters relating to medicinal products for human and veterinary use. EMA's main task is to co-ordinate the scientific evaluation of the safety, efficacy and quality of medicinal products which undergo either procedure. All scientific questions arising in these procedures are dealt with by the EMA.
The agency has today established itself as a world-leading agency for the evaluation of medicinal products. It constitutes a major asset in making Europe an attractive location for new pharmaceuticals and allows for speedy and robust authorisation of new innovative medicines.
EMA's key tasks are to:
  • provide Member States and Community institutions with the best possible scientific advice on questions about the quality, safety and efficacy of medicinal products for human and veterinary use;
  • establish a pool of multinational scientific expertise (by mobilising existing national resources) in order to achieve a single evaluation via the centralised or mutual recognition marketing authorisation procedures;
  • organise speedy, transparent and efficient procedures for the authorisation, surveillance and where appropriate, withdrawal of medicinal products in the EU;
  • advise companies on the conduct of pharmaceutical research;
  • reinforce the supervision of existing medicinal products (by co-ordinating national pharmacovigilance and inspection activities);
  • create databases and electronic communication facilities as necessary to promote the rational use of medicines.
