NOTES, Data exclusivity, Tecfidera, Dimethyl fumarate

Dimethyl fumarate

  Dimethyl fumarate
The CHMP has now completed its assessment and considers that dimethyl fumarate is different from Fumaderm
2. Therefore, the active substance of Tecfidera, dimethyl fumarate, is a new active substance. This conclusion is based on the review of the scientific evidence, and in line withclarification provided by the European Commission that:
i) a new active substance under Directive 2001/83/EC is a chemical substance not previouslyauthorised as a medicinal product in the European Union (Annex I to the Notice to applicants Volume 2A, Procedures for marketing authorisation, Chapter 1, Marketing authorisations, June 2013) and,ii) dimethyl fumarate is part of the medicinal product Fumaderm authorised in 1994 in Germany, but it has not been previously authorised as a medicinal product in the Euopean Union
The fact that tecfidera is new active substance under Directive 2001/83/EC it is eligible for 10 yrs exclusivity in EU

Tecfidera MA on 30 January 2014..........10 yrs from this date

Biogen Idec has won regulatory protection for its top-selling multiple sclerosis drug Tecfidera in Europe, paving the way for its launch in markets that could account for a large proportion of future sales.
The European Medicines Agency said on Friday it had granted the oral medicine a "new active substance" (NAS) designation, securing Biogen 10 years protection through data exclusivity that will stop generic firms from launching copycat versions.
In March, Tecfidera was approved in the United States and also recommended for approval in Europe - but its EU launch has been delayed, pending a resolution of uncertainty over data protection.
Without this protection, Biogen would have to rely on relatively weak patents relating the drug's use, which analysts believe might not prevent generic rivals launching cheaper copies in key markets like Germany.

Tecfidera was recommended on 25 March by Europe’s Committee for Medicinal Products for Human Use (CHMP) as a known active substance, rather than a new active substance. A Biogen spokesperson said it was entitled to 10 years’ exclusivity for Tecfidera in the EU under the “Independent Development” principle and its stand-alone data package. The EMA’s guidance on exclusivity will be announced when the final approval decision is given.
If Tecfidera is not granted exclusivity through new active substance status or the Independent Development principle, Biogen will only have patent protection in the EU rather than protection against competitors using its MS data for generic regulatory filings of Tecfidera. The company’s latest EU patent (EP 1131065) expires in 2019 and is directed to formulations of dimethyl fumarate and its uses for autoimmune diseases including MS, according to company documents.

Drug: BG00012
Other Names:
  • dimethyl fumarate
  • Tecfidera®

The proverbial thorn in Biogen Idec’s paw is a little used product called Fumaderm – which is approved in Germany for the treatment of psoriasis. A ‘chemical cousin’ of Tecfidera (Fumaderm is a compounded form of dimethyl fumarate – the active ingredient in Biogen Idec’s new MS treatment), Fumaderm generated sales of just $60 million in 2012 – a figure that Tecfidera is expected to surpass during its first three months of availability in the US market alone.
The similarities between Tecfidera and Fumaderm would appear to have guided Biogen Idec away from the pursuit of new active substance (NAS) status for Tecfidera – which ordinarily provides new product approvals a minimum of eight years data exclusivity and two years market exclusivity

Biogen Idec wins EU battle on Tecfidera exclusivity

Oral MS drug gains New Active Substance status
Biogen Idec building

Biogen Idec has been buoyed by victory in its longstanding battle to secure market exclusivity for its oral multiple sclerosis (MS) drug Tecfidera in the EU.

Shares in the US biopharma company climbed around 10 per cent on Friday after the Committee for Medicinal Products for Human Use (CHMP) agreed that the active ingredient in Tecfidera - dimethyl fumarate - should be classed as a New Active Substance (NAS) in the EU.
Biogen Idec has delayed the introduction of Tecfidera in Europe while the matter was resolved, and can now move ahead with a launch, secure in the knowledge that it has gained 10 years of regulatory exclusivity for the fast-growing product.
Tecfidera was approved in the US in March, becoming the third orally-active MS treatment to reach the market after Novartis' Gilenya (fingolimod) and Sanofi's Aubagio (teriflunomide), and has romped away in its first few months on the market, racking up around $500m in sales in its first six months.
The drug was awarded a European patent on May 29 that protects it from generic competition until 2028, but has also been pushing for regulatory data protection and NAS status, which will confer an additional level of protection against patent challenges.
Biogen Idec said in a statement that Tecfidera's EU approval has been delayed while the regulatory status of the drug is resolved, but now - with a CHMP positive opinion already in the bag - it can now be referred to the European Commission for a final ruling on the marketing application.
"We are ready to introduce Tecfidera in EU countries shortly after anticipated approval," said the company's executive vice president of R&D Douglas Williams.
Analysts have predicted that the drug could lead the market for oral MS therapies as they become established in favour of injectable interferon-based treatments, with sales of $3bn-a-year or more in 2016.

The European Commission granted a marketing authorisation valid throughout the European Union for Tecfidera on 30 January 2014  ie dimethyl fumarate

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.
