ACTION: Notice. The Food and Drug Administration’s (FDA’s) Center for Drug Evaluation and Research (CDER) is announcing the continuation of the Regulatory Project Management Site Tours and Regulatory Interaction Program (the Site Tours Program). The purpose of this document is to invite pharmaceutical companies interested in participating in this program to contact CDER. DATES: Pharmaceutical companies may send proposed agendas to the Agency by April 13, 2018. FOR FURTHER INFORMATION CONTACT: Dan Brum, Center for Drug Evaluation and Research, Food and Drug Administration, 10903 New Hampshire Ave., Bldg. 22, Rm. 5480, Silver Spring, MD 20993–0002, 301–796–0578, dan.brum@fda.hhs.gov. SUPPLEMENTARY INFORMATION: daltland on DSKBBV9HB2PROD with NOTICES SUMMARY: I. Background An important part of CDER’s commitment to make safe and effective drugs available to all Americans is optimizing the efficiency and quality of the drug review process. To support this VerDate Sep<11>2014 19:23 Feb 09, 2018 Jkt 244001 primary goal, CDER has initiated various training and development programs to promote high performance in its regulatory project management staff. CDER seeks to significantly enhance review efficiency and review quality by providing the staff with a better understanding of the pharmaceutical industry and its operations. To this end, CDER is continuing its training program to give regulatory project managers the opportunity to tour pharmaceutical facilities. The goals are to provide the following: (1) Firsthand exposure to industry’s drug development processes and (2) a venue for sharing information about project management procedures (but not drug-specific information) with industry representatives. II. The Site Tours Program In this program, over a 2- to 3-day period, small groups (five or less) of regulatory project managers, including a senior level regulatory project manager, can observe operations of pharmaceutical manufacturing and/or packaging facilities, pathology/ toxicology laboratories, and regulatory affairs operations. Neither this tour nor any part of the program is intended as a mechanism to inspect, assess, judge, or perform a regulatory function, but is meant rather to improve mutual understanding and to provide an avenue for open dialogue. During the Site Tours Program, regulatory project managers will also participate in daily workshops with their industry counterparts, focusing on selective regulatory issues important to both CDER staff and industry. The primary objective of the daily workshops is to learn about the team approach to drug development, including drug discovery, preclinical evaluation, tracking mechanisms, and regulatory submission operations. The overall benefit to regulatory project managers will be exposure to project management, team techniques, and processes employed by the pharmaceutical industry. By participating in this program, the regulatory project manager will grow professionally by gaining a better understanding of industry processes and procedures. III. Site Selection All travel expenses associated with the Site Tours Program will be the responsibility of CDER; therefore, selection will be based on the availability of funds and resources for each fiscal year. Selection will also be based on firms having a favorable facility status as determined by FDA’s Office of Regulatory Affairs District PO 00000 Frm 00054 Fmt 4703 Sfmt 4703 Offices in the firms’ respective regions. Firms that want to learn more about this training opportunity or that are interested in offering a site tour should respond by sending a proposed agenda by email directly to Dan Brum (see DATES and FOR FURTHER INFORMATION CONTACT).

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 PO 00000 Frm 00055 Fmt 4703 Sfmt 4703 6029 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 IMBRUVICA (ibrutinib). IMBRUVICA is indicated for treatment of patients with mantle cell lymphoma who have received at least one prior therapy. This indication is based on overall response rate. An improvement in survival of diseaserelated symptoms has not been established. Subsequent to this approval, the USPTO received a patent term restoration application for IMBRUVICA (U.S. Patent No. 8,008,309) from Pharmacyclics, Inc., and the USPTO requested FDA’s assistance in determining this patent’s eligibility for patent term restoration. In a letter dated October 20, 2015, FDA advised the USPTO that this human drug product had undergone a regulatory review period and that the approval of IMBRUVICA 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 IMBRUVICA is 1,865 days. Of this time, 1,726 days occurred during the testing phase of the regulatory review period, while 139 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 E:\FR\FM\12FEN1.SGM 12FEN1 6030 Federal Register / Vol. 83, No. 29 / Monday, February 12, 2018 / Notices U.S.C. 355(i)) became effective: October 7, 2008. The applicant claims September 8, 2008, as the date the investigational new drug application (IND) became effective. However, FDA records indicate that the IND effective date was October 7, 2008, which was 30 days after FDA receipt of the IND. 2. The date the application was initially submitted with respect to the human drug product under section 505(b) of the FD&C Act: June 28, 2013. FDA has verified the applicant’s claim that the new drug application (NDA) for IMBRUVICA (NDA 205552) was initially submitted on June 28, 2013. 3. The date the application was approved: November 13, 2013. FDA has verified the applicant’s claim that NDA 205552 was approved on November 13, 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 320 days of patent term extension. daltland on DSKBBV9HB2PROD 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 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 IMBRUVICA 
(ibrutinib). IMBRUVICA is indicated for treatment of patients with 
mantle cell lymphoma who have received at least one prior therapy. This 
indication is based on overall response rate. An improvement in 
survival of disease-related symptoms has not been established. 
Subsequent to this approval, the USPTO received a patent term 
restoration application for IMBRUVICA (U.S. Patent No. 8,008,309) from 
Pharmacyclics, Inc., and the USPTO requested FDA's assistance in 
determining this patent's eligibility for patent term restoration. In a 
letter dated October 20, 2015, FDA advised the USPTO that this human 
drug product had undergone a regulatory review period and that the 
approval of IMBRUVICA 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 
IMBRUVICA is 1,865 days. Of this time, 1,726 days occurred during the 
testing phase of the regulatory review period, while 139 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

[[Page 6030]]

U.S.C. 355(i)) became effective: October 7, 2008. The applicant claims 
September 8, 2008, as the date the investigational new drug application 
(IND) became effective. However, FDA records indicate that the IND 
effective date was October 7, 2008, which was 30 days after FDA receipt 
of the IND.
    2. The date the application was initially submitted with respect to 
the human drug product under section 505(b) of the FD&C Act: June 28, 
2013. FDA has verified the applicant's claim that the new drug 
application (NDA) for IMBRUVICA (NDA 205552) was initially submitted on 
June 28, 2013.
    3. The date the application was approved: November 13, 2013. FDA 
has verified the applicant's claim that NDA 205552 was approved on 
November 13, 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 320 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 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
