mdi ConsultantsThe Biologics Price Competition and Innovation Act of 2009
On March 23, 2010, President Obama signed into law The “Biologics Price Competition and Innovation Act of 2009” (“Biologics Act”) which is included as a subtitle to the Patient Protection and Affordable Care Act (“Healthcare Bill”). It created a framework for FDA approval of follow-on biologics.
The key provisions of the new Biologics Act are as follows:
• The Act uses the term “biological product,” for what is commonly called a“biologic” and defines “biological product” as a virus, therapeutic serum, toxin, antitoxin, vaccine, blood, blood component or derivative, allergenic product, protein(except any chemically synthesized polypeptide), or analogous product, or arsphenamine or derivative of arsphenamine (or any other trivalent organic arsenic compound), applicable to the prevention, treatment, or cure of a disease or condition of human beings. (Amending 42 U.S.C. § 262(i)).
• The Act defines “reference product” to mean the biological product against which follow-on biologic is evaluated.
An application for follow-on biologic must include the following certifications from the applicant:
• That the biological product is biosimilar to the reference product, based upon(a) data from analytical studies; and(b) data from animal studies (including toxicity studies); and(c) data from a clinical study or studies sufficient to demonstrate safety, purity, and potency in one or more “appropriate conditions of use for which the reference product is licensed and intended to be used and for which licensure is sought for the biological product.”
• That the biological product and reference product “utilize the same mechanism or mechanisms of action for the condition or conditions of use prescribed, recommended, or suggested in the proposed labeling” (but only to the extent such mechanism is actually known for the reference product);
• That the conditions of use in the labeling for the proposed biological product have been previously approved for the reference product;
• That the route of administration, dosage form, and strength of the biological product are the same as those of the reference product; and
• That the facility in which the biological product is manufactured meets standards designed to “assure that the biological product continues to be safe, pure, and potent.”
For a follow-on biologic to be deemed “biosimilar” or to achieve “biosimilarity,”
• Data must be produced to show that the biological product (a) is “highly similar” to the reference product “notwithstanding minor differences in clinically active components”; and (b) exhibits “no clinically meaningful differences” relative to the reference product in terms of safety, purity, and potency.
• A biosimilar drug is considered to have a new “active ingredient” compared to the reference product
For follow-on biologic to be deemed “interchangeable,”
• Data must be produced to show that the biological product (a) is biosimilar to the reference product; and (b) can be expected to produce the “same” clinical result “in any given patient” as the reference product. Furthermore, if the biological product is “administered more than once to an individual,” it will only be deemed interchangeable if the risk (in terms of safety or diminished efficacy) of alternating or switching between the biological product and the reference product “is not greater than the risk of using the reference product without such alternation or switch.”
• A biological product that is interchangeable will be considered to have the same “active ingredient” as the reference product.
Exclusivity for Reference Product
• No follow-on biologic application may be submitted until four years from the date on which the reference product was first licensed by the FDA.
• No follow-on biologic application may be approved until twelve years from the date on which the reference product was first licensed by the FDA.
• An additional six months of exclusivity may be obtained for approved pediatric or rare disease indications.
Exclusivity for First Interchangeable Biological Product
• If a follow-on biologic is approved by the FDA and is deemed to be interchangeable (not merely biosimilar), then the applicant receives the lesser of one year of exclusivity after the date of first commercial marketing or eighteen months of exclusivity after FDA approval vis-à-vis any other approved, interchangeable follow-on biological products.
Patent Infringement Issues
• An immediately recognizable difference between the Biologics Act and small molecule/Hatch-Waxman frameworks is that there is no “Orange Book”for biologics to list patents that cover the reference product. Instead, the new law requires a process of information sharing between the follow-on biologic applicant and the reference product “sponsor” (typically the patent holder or licensee).
• Within twenty days of notification that its application has been accepted for FDA review, the follow-on applicant must provide limited confidential access to a copy of the application to the reference product sponsor.
• Within sixty days after receiving confidential access to the application, the reference product sponsor must (1) provide the follow-on applicant with alist of patents for which a claim of patent infringement is believed could be reasonably asserted; and (2) identify the patents on this list that the reference product sponsor would be prepared to license to the applicant (if any).
• Within sixty days after receiving the reference product sponsor’s patent “list,” the follow-on applicant must provide to the reference product sponsor, with respect to each patent on the list: (1) a detailed statement describing the factual and legal basis of the opinion of the applicant that such patent is invalid, unenforceable, or will not be infringed (the equivalent of a Paragraph IV letter under Hatch-Waxman); or (2) a statement that the applicant does not intend to begin commercial marketing of the biological product before the date that such patent expires (the equivalent of a Paragraph III certification). The applicant must also provide a response regarding the patents the reference product sponsor indicates it would be prepared to license.
• Within sixty days after receiving the applicant’s response, the reference product sponsor must (1) provide a detailed statement describing the factual and legal basis for why each listed patent will be infringed; and (2) provide a “response” to the applicant’s statement regarding validity and enforceability.
• After this information exchange period, the parties have two weeks to agree on which patents should be the subject of a patent infringement suit. If agreement is reached, the complaint must be filed within thirty days. If no agreement is reached, then a slightly different procedure is followed, but the complaint must nevertheless be filed in short order.
• Importantly, there is no thirty month stay akin to the Hatch-Waxman framework. However, the follow-on biologic applicant must provide the reference product sponsor with 180 day notice before commercial marketing, thus allowing the reference product sponsor to seek a preliminary injunction against the follow-on biologic entering the market.
Conclusion
The Biologics Price Competition and Innovation Act of 2009 is a brand new law, with brand new language that will need to be analyzed by regulatory agencies, courts, and practitioners.
