Determination of Regulatory Review Period for Purposes of Patent Extension; DUAVEE, 4487-4489 [2018-01894]

Download as PDF sradovich on DSK3GMQ082PROD with NOTICES Federal Register / Vol. 83, No. 21 / Wednesday, January 31, 2018 / Notices A regulatory review period consists of two periods of time: A testing phase and an approval phase. For medical devices, the testing phase begins with a clinical investigation of the device and runs until the approval phase begins. The approval phase starts with the initial submission of an application to market the device and continues until permission to market the device is granted. Although only a portion of a regulatory review period may count toward the actual amount of extension that the Director of USPTO may award (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 medical device will include all of the testing phase and approval phase as specified in 35 U.S.C. 156(g)(3)(B). FDA has approved for marketing the medical device SAPIEN XT TRANSCATHETER HEART VALVE. SAPIEN XT TRANSCATHETER HEART VALVE is indicated for relief of aortic stenosis in patients with symptomatic heart disease due to severe native calcific aortic stenosis (aortic valve area ≤1.0 cm2 or aortic valve area index ≤0.6 cm2/m2, a mean aortic valve gradient of ≥40 mmHg, or a peak aortic-jet velocity of ≥4.0 m/s), and with native anatomy appropriate for the 23, 26, or 29 mm valve system, who are judged by a heart team, including a cardiac surgeon, to be at high or greater risk for open surgical therapy (i.e., Society of Thoracic Surgeons operative risk score ≥8% or at a ≥15% risk of morality at 30 days). Subsequent to this approval, the USPTO received a patent term restoration application for SAPIEN XT TRANSCATHETER HEART VALVE (U.S. Patent Nos. 7,510,575 and 7,585,321) from Edwards Lifesciences PVT, Inc., and the USPTO requested FDA’s assistance in determining the patents’ eligibility for patent term restoration. In a letter dated October 15, 2015, FDA advised the USPTO that this medical device had undergone a regulatory review period and that the approval of SAPIEN XT TRANSCATHETER HEART VALVE represented the first permitted commercial marketing or use of the product. Thereafter, the USPTO requested that FDA determine the product’s regulatory review period. II. Determination of Regulatory Review Period FDA has determined that the applicable regulatory review period for SAPIEN XT TRANSCATHETER HEART VALVE is 1,370 days. Of this time, 959 days occurred during the testing phase VerDate Sep<11>2014 17:36 Jan 30, 2018 Jkt 244001 of the regulatory review period, while 411 days occurred during the approval phase. These periods of time were derived from the following dates: 1. The date an exemption under section 520(g) of the Federal Food, Drug, and Cosmetic Act (the FD&C Act) (21 U.S.C. 360j(g)) involving this device became effective: September 17, 2010. FDA has verified the applicant’s claim that the date the investigational device exemption became effective was on September 17, 2010. 2. The date an application was initially submitted with respect to the device under section 515 of the FD&C Act (21 U.S.C. 360e): May 2, 2013. FDA has verified the applicant’s claim that the premarket approval application (PMA) for SAPIEN XT TRANSCATHETER HEART VALVE (PMA P130009) was initially submitted on May 2, 2013. 3. The date the application was approved: June 16, 2014. FDA has verified the applicant’s claim that PMA P130009 was approved on June 16, 2014. 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 applications for patent extension, this applicant seeks 889 days of patent term extension. III. Petitions Anyone with knowledge that any of the dates as published are incorrect may submit either electronic or written comments and, under 21 CFR 60.24, ask for a redetermination (see DATES). Furthermore, as specified in 21 CFR 60.30, any interested person may petition FDA for a determination regarding whether the applicant for extension acted with due diligence during the regulatory review period. To meet its burden, the petition must comply with all the requirements of 21 CFR 60.30, including but not limited to: Must be timely (see DATES), must be filed in accordance with 21 CFR 10.20, must contain sufficient facts to merit an FDA investigation, and must certify that a true and complete copy of the petition has been served upon the patent applicant.

SUPPLEMENTARY INFORMATION:

I. Background

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 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 DUAVEE
(conjugated estrogens/bazedoxifene acetate). DUAVEE is indicated for
treatment of the following conditions in women with a uterus: (1)
Treatment of moderate to severe vasomotor symptoms associated with
menopause and (2) prevention of postmenopausal osteoporosis. Subsequent
to this approval, the USPTO received patent term restoration
applications for DUAVEE (U.S. Patent Nos. 5,998,402 and 6,479,535) from
Wyeth LLC, and the USPTO requested FDA's assistance in determining the
patents' eligibility for patent term restoration. In a letter dated
November 3, 2015, FDA advised the USPTO that this human drug product
had undergone a regulatory review period and that the approval of
DUAVEE represented the first permitted commercial marketing or use of
the product. Thereafter, the USPTO requested that FDA determine the
product's regulatory review period.

II. Determination of Regulatory Review Period

FDA has determined that the applicable regulatory review period for
DUAVEE is 5,683 days. Of this time, 5,317 days occurred during the
testing phase of the regulatory review period, while 366 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: March 15, 1998. FDA has verified the Wyeth LLC claim that
March 15, 1998, is the date the investigational new drug application
(IND) became effective.

[[Page 4489]]

2. The date the application was initially submitted with respect to
the human drug product under section 505(b) of the FD&C Act: October 3,
2012. FDA has verified the applicant's claim that the new drug
application (NDA) for DUAVEE (NDA 022247) was initially submitted on
October 3, 2012.
3. The date the application was approved: October 3, 2013. FDA has
verified the applicant's claim that NDA 022247 was approved on October
3, 2013.
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.

III. Petitions

Anyone with knowledge that any of the dates as published are
incorrect may submit either electronic or written comments and, under
21 CFR 60.24, ask for a redetermination (see DATES). Furthermore, as
specified in Sec. 60.30 (21 CFR 60.30), any interested person may
petition FDA for a determination regarding whether the applicant for
extension acted with due diligence during the regulatory review period.
To meet its burden, comply with all the requirements of Sec. 60.30,
including but not limited to: Must be timely (see DATES), must be filed
in accordance with Sec. 10.20, must contain sufficient facts to merit
an FDA investigation, and must certify that a true and complete copy of
