Determination of Regulatory Review Period for Purposes of Patent 
Extension; JUXTAPID

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA) has determined the 
regulatory review period for JUXTAPID and is publishing this notice of 
that determination as required by law. FDA has made the determination 
because of the submission of an application to the Director of the U.S. 
Patent and Trademark Office (USPTO), Department of Commerce, for the 
extension of a patent which claims that human drug product.

ADDRESSES: Submit electronic comments to http://www.regulations.gov. 
Submit written petitions (two copies are required) and written comments 
to the Division of Dockets Management (HFA-305), Food and Drug 
Administration, 5630 Fishers Lane, Rm. 1061, Rockville, MD 20852. 
Submit petitions electronically to http://www.regulations.gov at Docket 
No. FDA-2013-S-0610.

FOR FURTHER INFORMATION CONTACT: Beverly Friedman, Office of 
Management, Food and Drug Administration, 10001 New Hampshire Ave.,

SUPPLEMENTARY INFORMATION: The Drug Price Competition and Patent Term 
Restoration Act of 1984 (Pub. L. 98-417) and the Generic Animal Drug 
and Patent Term Restoration Act (Pub, L. 100-670) generally provide 
that a patent may be extended for a period of up to 5 years so long as 
the patented item (human drug product, animal drug product, medical 
device, food additive, or color additive) was subject to regulatory 
review by FDA before the item was marketed. Under these acts, a 
product's regulatory review period forms the basis for determining the 
amount of extension an applicant may receive.
    A regulatory review period consists of two periods of time: A 
testing phase and an approval phase. For human drug products, the 
testing phase begins when the exemption to permit the clinical 
investigations of the drug becomes effective and runs until the 
approval phase begins. The approval phase starts with the initial 
submission of an application to market the human drug product and 
continues until FDA grants permission to market the drug product. 
Although only a portion of a regulatory review period may count toward 
the actual amount of extension that the Director of the U.S. Patent and 
Trademark Office (USPTO) may award (for example, half the testing phase 
must be subtracted as well as any time that may have occurred before 
the patent was issued), FDA's determination of the length of a 
regulatory review period for a human drug product will include all of 
the testing phase and approval phase as specified in 35 U.S.C. 
156(g)(1)(B).
    FDA has approved for marketing the human drug product JUXTAPID 
(lomitapide mesylate). JUXTAPID is indicated as an adjunct to a low-fat 
diet and other lipid-lowering treatments, including LDL apheresis where 
available, to reduce low-density lipoprotein cholesterol, total 
cholesterol, apolipoprotein B, and non-high-density lipoprotein 
cholesterol in patients with homozygous familial hypercholesterolemia. 
Subsequent to this approval, the USPTO received a patent term 
restoration application for JUXTAPID (U.S. Patent No. 5,712,279) from 
Aegerion Pharmaceuticals, Inc., and the USPTO requested FDA's 
assistance in determining this patent's eligibility for patent term 
restoration. In a letter dated January 31, 2014, FDA advised the USPTO 
that this human drug product had undergone a regulatory review period 
and that the approval of JUXTAPID represented the first permitted 
commercial marketing or use of the product. Thereafter, the USPTO 
requested that FDA determine the product's regulatory review period.
    FDA has determined that the applicable regulatory review period for 
JUXTAPID is 6,002 days. Of this time, 5,705 days occurred during the 
testing phase of the regulatory review period, while 297 days occurred 
during the approval phase. These periods of time were derived from the 
following dates:
    1. The date an exemption under section 505(i) of the Federal Food, 
Drug, and Cosmetic Act (the FD&C Act) (21 U.S.C. 355(i)) became 
effective: July 18, 1996. FDA has verified the applicant's claim that 
the date the investigational new drug application became effective was 
on July 18, 1996.
    2. The date the application was initially submitted with respect to 
the human drug product under section 505(b) of the FD&C Act: February 
29, 2012. FDA has verified the applicant's claim that the new drug 
application (NDA) for Juxtapid (NDA 203-858) was submitted on February 
29, 2012.
    3. The date the application was approved: December 21, 2012. FDA 
has verified the applicant's claim that NDA 203-858 was approved on 
December 21, 2012.
    This determination of the regulatory review period establishes the 
maximum potential length of a patent extension. However, the USPTO 
applies several statutory limitations in its calculations of the actual 
period for patent extension. In its application for patent extension, 
this applicant seeks 5 years of patent term extension.
    Anyone with knowledge that any of the dates as published are 
incorrect may submit to the Division of Dockets Management (see 
ADDRESSES) either electronic or written comments and ask for a 
redetermination by June 5, 2015. Furthermore, any interested person may 
petition FDA for a determination regarding whether the applicant for 
extension acted with due diligence during the regulatory review period 
by October 5, 2015. To meet its burden, the petition must contain 
sufficient facts to merit an FDA investigation. (See H. Rept. 857, part 
1, 98th Cong., 2d sess., pp. 41-42, 1984.) Petitions should be in the 
format specified in 21 CFR 10.30.
    Interested persons may submit to the Division of Dockets Management 
(see ADDRESSES) electronic or written comments and written or 
electronic petitions. It is only necessary to send one set of comments. 
Identify comments with the docket number found in brackets in the 
heading of this document. If you submit a written petition, two copies 
are required. A petition submitted electronically must be submitted to 
http://www.regulations.gov, Docket No. FDA-2013-S-0610. Comments and 
petitions that have not been made publicly available on http://www.regulations.gov may be viewed in the Division of Dockets Management 
between 9 a.m. and 4 p.m., Monday through Friday.

    Dated: April 1, 2015.

Associate Commissioner for Policy.
