Determination of Regulatory Review Period for Purposes of Patent Extension; IMLYGIC, 95618-95620 [2016-31322]

Download as PDF sradovich on DSK3GMQ082PROD with NOTICES 95618 Federal Register / Vol. 81, No. 249 / Wednesday, December 28, 2016 / Notices Furthermore, Presidential Policy Directive 21—Critical Infrastructure Security and Resilience (PPD–21) issued on February 12, 2013 tasks Federal Government entities to strengthen the security and resilience of critical infrastructure against physical and cyber threats such that these efforts reduce vulnerabilities, minimize consequences, and identify and disrupt threats. PPD–21 encourages all public and private stakeholders to share responsibility in achieving these outcomes. In recognition of the shared responsibility for cybersecurity, the security industry has established resources including standards, guidelines, best practices and frameworks for stakeholders to adopt a culture of cybersecurity risk management. Best practices include collaboratively assessing cybersecurity intelligence information for risks to device functionality and clinical risk. FDA believes that, in alignment with Executive Order 13636 and PPD–21, public and private stakeholders should collaborate to leverage available resources and tools to establish a common understanding that assesses risks for identified vulnerabilities in medical devices among the information technology community, healthcare delivery organizations, the clinical user community, and the medical device community. These collaborations can lead to the consistent assessment and mitigation of cybersecurity threats, and their impact on medical device safety and effectiveness, ultimately reducing potential risk of patient harm. Part 806 (21 CFR part 806) requires device manufacturers or importers to report promptly to FDA certain actions concerning device corrections and removals. However, the majority of actions taken by manufacturers to address cybersecurity vulnerabilities and exploits, referred to as ‘‘cybersecurity routine updates and patches,’’ are generally considered to be a type of device enhancement for which the FDA does not require advance notification or reporting under part 806. For a small subset of actions taken by manufacturers to correct device cybersecurity vulnerabilities and exploits that may pose a risk to health, the FDA would require medical device manufacturers to notify the Agency. This guidance clarifies changes to devices to be considered cybersecurity routine updates and patches (e.g., certain actions to maintain a controlled risk to health). In addition, the guidance outlines circumstances in which FDA does not intend to enforce reporting requirements under part 806 for specific VerDate Sep<11>2014 18:54 Dec 27, 2016 Jkt 241001 vulnerabilities with uncontrolled risk. Specifically, FDA does not intend to enforce the reporting requirements when circumstances outlined in the guidance are met within the predefined periods of time (e.g., communicate vulnerability to customers and user community and propose a timeline for remediation within 30 days after learning of the vulnerability; fix the vulnerability and validate the change within 60 days after learning of the vulnerability; actively participate in an Information Sharing Analysis Organization (ISAO)). The Agency considers voluntary participation in an Information ISAO a critical component of a medical device manufacturer’s comprehensive proactive approach to management of postmarket cybersecurity threats and vulnerabilities and a significant step towards assuring the ongoing safety and effectiveness of marketed medical devices. II. Significance of Guidance This guidance is being issued consistent with FDA’s good guidance practices regulation (21 CFR 10.115). The guidance represents the current thinking of FDA on ‘‘Postmarket Management of Cybersecurity in Medical Devices.’’ It does not establish any rights for any person and is not binding on FDA or the public. You can use an alternative approach if it satisfies the requirements of the applicable statutes and regulations. III.

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 PO 00000 Frm 00065 Fmt 4703 Sfmt 4703 95619 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 biological products, the testing phase begins when the exemption to permit the clinical investigations of the biological becomes effective and runs until the approval phase begins. The approval phase starts with the initial submission of an application to market the human biological product and continues until FDA grants permission to market the biological 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 biological 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 biologic product IMLYGIC (talimogene laherparepvec). IMLYGIC is indicated for the local treatment of unresectable cutaneous, subcutaneous, and nodal lesions in patients with melanoma recurrent after initial surgery. Subsequent to this approval, the USPTO received patent term restoration applications for IMLYGIC (U.S. Patent Nos. 7,063,835; 7,223,593; and 7,537,924) from BioVex Limited, and the USPTO requested FDA’s assistance in determining the patents’ eligibility for patent term restoration. In a letter dated July 12, 2016, FDA advised the USPTO that this human biological product had undergone a regulatory review period and that the approval of IMLYGIC 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 IMLYGIC is 3,809 days. Of this time, 3,352 days occurred during the testing E:\FR\FM\28DEN1.SGM 28DEN1 95620 Federal Register / Vol. 81, No. 249 / Wednesday, December 28, 2016 / Notices phase of the regulatory review period, while 457 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 (21 U.S.C. 355(i)) became effective: May 25, 2005. FDA has verified the applicant’s claim that the date the investigational new drug application became effective was on May 25, 2005. 2. The date the application was initially submitted with respect to the human biological product under section 351 of the Public Health Service Act (42 U.S.C. 262): July 28, 2014. FDA has verified the applicant’s claim that the biologics license application (BLA) for IMLYGIC (BLA 125518) was initially submitted on July 28, 2014. 3. The date the application was approved: October 27, 2015. FDA has verified the applicant’s claim that BLA 125518 was approved on October 27, 2015. 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 1,826 days, 1,764 days, or 1400 days, respectively, of patent term extension. sradovich on DSK3GMQ082PROD with NOTICES III.

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 biological products, the
testing phase begins when the exemption to permit the clinical
investigations of the biological becomes effective and runs until the
approval phase begins. The approval phase starts with the initial
submission of an application to market the human biological product and
continues until FDA grants permission to market the biological 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
biological 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 biologic product IMLYGIC
(talimogene laherparepvec). IMLYGIC is indicated for the local
treatment of unresectable cutaneous, subcutaneous, and nodal lesions in
patients with melanoma recurrent after initial surgery. Subsequent to
this approval, the USPTO received patent term restoration applications
for IMLYGIC (U.S. Patent Nos. 7,063,835; 7,223,593; and 7,537,924) from
BioVex Limited, and the USPTO requested FDA's assistance in determining
the patents' eligibility for patent term restoration. In a letter dated
July 12, 2016, FDA advised the USPTO that this human biological product
had undergone a regulatory review period and that the approval of
IMLYGIC 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
IMLYGIC is 3,809 days. Of this time, 3,352 days occurred during the
testing

[[Page 95620]]

phase of the regulatory review period, while 457 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 (21 U.S.C. 355(i)) became effective: May 25,
2005. FDA has verified the applicant's claim that the date the
investigational new drug application became effective was on May 25,
2005.
2. The date the application was initially submitted with respect to
the human biological product under section 351 of the Public Health
Service Act (42 U.S.C. 262): July 28, 2014. FDA has verified the
applicant's claim that the biologics license application (BLA) for
IMLYGIC (BLA 125518) was initially submitted on July 28, 2014.
3. The date the application was approved: October 27, 2015. FDA has
verified the applicant's claim that BLA 125518 was approved on October
27, 2015.
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 1,826 days, 1,764 days, or 1400 days,
respectively, 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 ask for
a redetermination (see DATES). 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.
To meet its burden, the petition must be timely (see DATES) and 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.
Submit petitions electronically to https://www.regulations.gov at
Docket No. FDA-2013-S-0610. Submit written petitions (two copies are
required) to the Division of Dockets Management (HFA-305), Food and
Drug Administration, 5630 Fishers Lane, Rm. 1061, Rockville, MD 20852.
