Determination of Regulatory Review Period for Purposes of Patent 
Extension; BARRICAID ANULAR CLOSURE DEVICE

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice.

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

SUMMARY: The Food and Drug Administration (FDA or the Agency) has 
determined the regulatory review period for BARRICAID ANULAR CLOSURE 
DEVICE and is publishing this notice of that determination as required 
by law. FDA has made the determination because of the submission of 
applications to the Director of the U.S. Patent and Trademark Office 
(USPTO), Department of Commerce, for the extension of a patent which 
claims that medical device.

DATES: Anyone with knowledge that any of the dates as published (see 
SUPPLEMENTARY INFORMATION) are incorrect may submit either electronic 
or written comments and ask for a redetermination by October 3, 2023. 
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 January 31, 2024. See 
``Petitions'' in the SUPPLEMENTARY INFORMATION section for more 
information.

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 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 BARRICAID ANULAR 
CLOSURE DEVICE. The BARRICAID ANULAR CLOSURE DEVICE is indicated for 
reducing the incidence of reherniation and reoperation in skeletally 
mature patients with radiculopathy (with or without back pain) 
attributed to a posterior or posterolateral herniation, and confirmed 
by history, physical examination, and imaging studies that demonstrate 
neural compression using magnetic resonance imaging to treat a large 
anular defect (between 4 and 6 millimeters (mm) tall and between 6 and 
10 mm wide) following a primary discectomy procedure (excision of 
herniated intervertebral disc) at a single level between L4 and S1. 
Subsequent to this approval, the USPTO received patent term restoration 
applications for BARRICAID ANULAR CLOSURE DEVICE (U.S. Patent Nos. 
6,425,919; 7,524,333; 9,610,106) from Intrinsic Therapeutics, Inc., and 
the USPTO requested FDA's assistance in determining the patents' 
eligibility for patent term restoration. In a letter dated January 21, 
2020, FDA advised the USPTO that this medical device had undergone a 
regulatory review period and that the approval of BARRICAID ANULAR 
CLOSURE DEVICE 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 
BARRICAID ANULAR CLOSURE DEVICE is 2,980 days. Of this time, 2,163 days 
occurred during the testing phase of the regulatory review period, 
while 817 days occurred during the approval phase. These periods of 
time were derived from the following dates:
    1. The date a clinical investigation on humans is begun (21 CFR 
60.22(c)(1)(iii): December 14, 2010. FDA has verified the applicant's 
claim that the date the first clinical investigation in human subjects 
involving the BARRICAID ANULAR CLOSURE DEVICE as part of a clinical 
investigation filed with FDA to secure premarket approval of the device 
began December 14, 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): November 
14, 2016. The applicant claims November 10, 2016, as the date the 
premarket approval application (PMA) for BARRICAID ANULAR CLOSURE 
DEVICE (PMA P160050) was initially submitted. However, FDA records 
indicate that PMA P160050 was officially submitted on November 14, 
2016.
    3. The date the application was approved: February 8, 2019. FDA has 
verified the applicant's claim that PMA P160050 was approved on 
February 8, 2019.
    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 676 days or 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, the petition must 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 the petition has been served upon the patent 
applicant. (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.
    Submit petitions electronically to https://www.regulations.gov at 
Docket No. FDA-2013-S-0610. Submit written petitions (two copies are 
required) to the Dockets Management Staff (HFA-305), Food and Drug 
Administration, 5630 Fishers Lane, Rm. 1061, Rockville, MD 20852.
