Under the regulations, an owner, operator, or agent in charge of a facility must prepare, or have prepared, and implement a written food defense plan, including written identification of actionable process steps, written mitigation strategies, written procedures for defense monitoring, written food defense corrective actions, and written food defense verification procedures. The estimated recordkeeping burden associated with these activities totals 2,516,482 annual recordkeeping burden hours and 409,486 annual recordkeeping responses. We estimate an average of 3,247 firms will continue to need to create a food defense plan under § 121.126, that a one-time burden of 60 hours will be needed to create a plan, and that a burden of 10 hours will be required to update the plan. We annualize this estimate by dividing the total number of burden hours (70) over a 3-year period as reflected in table 2, row 1. Under § 121.130, each of the estimated 9,759 food production facilities will identify and specify actionable process steps for its food defense plan. We estimate that an individual at the level of an operations manager incurs a burden of 20 hours for this activity, as reflected in table 2, row 2. Under § 121.135(b), each of the estimated 9,759 food production VerDate Sep<11>2014 17:36 Jun 10, 2019 Jkt 247001 facilities must identify and implement mitigation strategies to provide assurances that any significant vulnerability at each step is significantly minimized or prevented, ensuring that the food manufactured, processed, packed, or held by the facility will not be adulterated. We do not specify a specific number or set of mitigation strategies to be implemented. Some of the covered facilities are already implementing mitigation strategies. We estimate that it requires an average of 20 hours per facility to satisfy the recordkeeping burden associated with these activities for a total of 195,180 hours, as reflected in table 2, row 3. We estimate that the recordkeeping activities associated with monitoring, documenting mitigation strategies, and implementing necessary corrective actions require first-line supervisors or others responsible for quality control an average of 175 hours for each recordkeeping, and that these provisions apply to each of the 9,759 facilities. This results in a total of 1,707,825 annual burden hours, as reflected in table 2, row 4. We estimate that recordkeeping activities associated with training under § 121.4 total 244,802 annual burden hours, as reflected in table 2, row 5. We estimate that there are 1.2 million employees working at the regulated facilities and that 30 percent of them PO 00000 Frm 00059 Fmt 4703 Sfmt 4703 (367,203) require training. We estimate that the average burden for the associated recordkeeping activity is approximately 40 minutes (or 0.67 hours) per record. Finally, we estimate the 9,759 food production facilities will fulfill the recordkeeping requirements under §§ 121.305 and 121.310, and that it will require an average of 10 hours per record, as reflected in table 2, row 6.

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 NDA 208610 for marketing the human drug product, BAXDELA TABLETS (delafloxacin meglumine) indicated in adults for the treatment of acute bacterial skin and skin structure infections caused by E:\FR\FM\11JNN1.SGM 11JNN1 Federal Register / Vol. 84, No. 112 / Tuesday, June 11, 2019 / Notices khammond on DSKBBV9HB2PROD with NOTICES designated susceptible bacteria. Subsequent to the NDA approvals, the USPTO received patent term restoration applications for BAXDELA (U.S. Patent Nos. 7,728,143 and 8,252,813) from Melinta Therapeutics, Inc., and the USPTO requested FDA’s assistance in determining the patents’ eligibility for patent term restoration. In a letter dated February 2, 2018, FDA advised the USPTO that this human drug product had undergone a regulatory review period and that the approvals of BAXDELA TABLETS and BAXDELA IV INJECTION represent the first permitted commercial marketing or use of the products. Thereafter, the USPTO requested that FDA determine the products’ regulatory review period. II. Determination of Regulatory Review Period FDA has determined that the applicable regulatory review period for BAXDELA TABLETS is 5,813 days. Of this time, 5,569 days occurred during the testing phase of the regulatory review period, while 244 days occurred during the approval phase. These periods of time were derived from the following dates: NDA 208610: 1. The date an exemption under section 505(i) of the Federal Food, Drug, and Cosmetic Act (FD&C Act) (21 U.S.C. 355(i)) became effective: July 22, 2001. Melinta Therapeutics, Inc., claims that July 27, 2001, is the date the investigational new drug application (IND) became effective. However, FDA records indicate that the IND effective date was July 22, 2001, which was 30 days after FDA receipt of the first IND. 2. The date new drug application 208610 was initially submitted with respect to the human drug product under section 505 of the FD&C Act: October 19, 2016. FDA has verified the applicant’s claim that the new drug application (NDA) for BAXDELA (NDA 208610) was submitted on October 19, 2016. 3. The date the application was approved: June 19, 2017. FDA has verified the applicant’s claim that NDA 208610 was approved on June 19, 2017. 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 1,307 or 1,001 days of patent term extension. III. Petitions Anyone with knowledge that any of the dates as published are incorrect may VerDate Sep<11>2014 17:36 Jun 10, 2019 Jkt 247001 submit either electronic or written comments and, under 21 CFR 60.24, ask for a redetermination (see DATES). Furthermore, as specified in § 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 § 60.30, including but not limited to: Must be timely (see DATES), must be filed in accordance with § 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.

SUPPLEMENTARY INFORMATION: In 1984, Congress enacted the Drug Price Competition and Patent Term Restoration Act of 1984 (Pub. L. 98–417) (the 1984 amendments), which authorized the approval of duplicate versions of drug products under an ANDA procedure. ANDA applicants must, with certain exceptions, show that the drug for which they are seeking approval contains the same active ingredient in the same strength and dosage form as the ‘‘listed drug,’’ which is a version of the drug that was previously approved. ANDA applicants do not have to repeat the extensive clinical testing otherwise necessary to gain approval of a new drug application (NDA). The 1984 amendments include what is now section 505(j)(7) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 355(j)(7)), which requires FDA to publish a list of all approved drugs. FDA publishes this list as part of the ‘‘Approved Drug Products with Therapeutic Equivalence Evaluations,’’ which is known generally as the ‘‘Orange Book.’’ Under FDA regulations, drugs are removed from the list if the Agency withdraws or suspends approval of the drug’s NDA or ANDA for reasons of safety or effectiveness or if FDA determines that the listed drug was withdrawn from sale for reasons of safety or effectiveness (21 CFR 314.162). A person may petition the Agency to determine, or the Agency may determine on its own initiative, whether a listed drug was withdrawn from sale for reasons of safety or effectiveness. This determination may be made at any time after the drug has been withdrawn from sale, but must be made prior to approving an ANDA that refers to the listed drug (§ 314.161 (21 CFR 314.161)). FDA may not approve an ANDA that does not refer to a listed drug. NIZORAL (ketoconazole) topical cream, 2%, is the subject of NDA 019084, previously held by Johnson & Johnson Pharmaceutical Research and Development, LLC and initially approved on December 31, 1985. NIZORAL is indicated for the topical treatment of tinea corporis, tinea cruris, and tinea pedis caused by Trichophyton rubrum, T. mentagrophytes, and Epidermophyton floccosum; of tinea (pityriasis) versicolor caused by Malassezia furfur (Pityrosporum orbiculare); of cutaneous candidiasis caused by Candida spp.; and of seborrheic dermatitis.

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 NDA 208610 for marketing the human drug product,
BAXDELA TABLETS (delafloxacin meglumine) indicated in adults for the
treatment of acute bacterial skin and skin structure infections caused
by

[[Page 27135]]

designated susceptible bacteria. Subsequent to the NDA approvals, the
USPTO received patent term restoration applications for BAXDELA (U.S.
Patent Nos. 7,728,143 and 8,252,813) from Melinta Therapeutics, Inc.,
and the USPTO requested FDA's assistance in determining the patents'
eligibility for patent term restoration. In a letter dated February 2,
2018, FDA advised the USPTO that this human drug product had undergone
a regulatory review period and that the approvals of BAXDELA TABLETS
and BAXDELA IV INJECTION represent the first permitted commercial
marketing or use of the products. Thereafter, the USPTO requested that
FDA determine the products' regulatory review period.

II. Determination of Regulatory Review Period

FDA has determined that the applicable regulatory review period for
BAXDELA TABLETS is 5,813 days. Of this time, 5,569 days occurred during
the testing phase of the regulatory review period, while 244 days
occurred during the approval phase. These periods of time were derived
from the following dates:
NDA 208610:
1. The date an exemption under section 505(i) of the Federal Food,
Drug, and Cosmetic Act (FD&C Act) (21 U.S.C. 355(i)) became effective:
July 22, 2001. Melinta Therapeutics, Inc., claims that July 27, 2001,
is the date the investigational new drug application (IND) became
effective. However, FDA records indicate that the IND effective date
was July 22, 2001, which was 30 days after FDA receipt of the first
IND.
2. The date new drug application 208610 was initially submitted
with respect to the human drug product under section 505 of the FD&C
Act: October 19, 2016. FDA has verified the applicant's claim that the
new drug application (NDA) for BAXDELA (NDA 208610) was submitted on
October 19, 2016.
3. The date the application was approved: June 19, 2017. FDA has
verified the applicant's claim that NDA 208610 was approved on June 19,
2017.
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 1,307 or 1,001 days of patent term extension.

III. Petitions

Anyone with knowledge that any of the dates as published are
