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, Tukysa (tucatinib) 

indicated in combination with 

trastuzumab and capecitabine for 

treatment of adult patients with 

advanced unresectable or metastatic 

HER2-positive breast cancer, including 

patients with brain metastases, who 

have received one or more prior antiHER2-based regimens in the metastatic 

setting. Subsequent to this approval, the 

USPTO received patent term restoration 

applications for Tukysa (U.S. Patent 

Nos. 7,452,895; 8,648,087; 9,457,093; 

and 9,693,989) from Array BioPharma 

Inc. and Seattle Genetics, Inc. (Agent of 

Array BioPharma Inc.) and the USPTO 

requested FDA’s assistance in 

determining the patents’ eligibility for 

patent term restoration. In a letter dated 

September 28, 2022, FDA advised the 

USPTO that this human drug product 

had undergone a regulatory review 

period and that the approval of Tukysa 

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 

Tukysa is 4,653 days. Of this time, 4,533 

days occurred during the testing phase 

of the regulatory review period, while 

120 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 (FD&C Act) (21 U.S.C. 

355(i)) became effective: July 24, 2007. 

FDA has verified the applicant’s claims 

that the date the investigational new 

drug application became effective was 

on July 24, 2007. 

2. The date the application was 

initially submitted with respect to the 

human drug product under section 505 

of the FD&C Act: December 20, 2019. 

FDA has verified the applicant’s claims 

that the new drug application (NDA) for 

Tukysa (NDA 213411) was initially 

submitted on December 20, 2019. 

3. The date the application was 

approved: April 17, 2020. FDA has 

verified the applicant’s claim that NDA 

213411 was approved on April 17, 2020. 

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 552 days, 570 days, 

1,101 days or 1,826 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 § 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: 

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 or biologic 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, Kerendia 

(finerenone) indicated to reduce the risk 

of sustained eGFR decline, end stage 

kidney disease, cardiovascular death, 

non-fatal myocardial infarction, and 

hospitalization for heart failure in adult 

patients with chronic kidney disease 

associated with type 2 diabetes. 

Subsequent to this approval, the USPTO 

received a patent term restoration 

application for Kerendia (U.S. Patent 

No. 8,436,180) from Bayer Intellectual 

Property GmbH and the USPTO 

requested FDA’s assistance in 

determining the patent’s eligibility for 

patent term restoration. In a letter dated 

September 13, 2022, FDA advised the 

USPTO that this human drug product 

had undergone a regulatory review 

period and that the approval of 

Kerendia 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 

Kerendia is 2,950 days. Of this time, 

2,707 days occurred during the testing 

phase of the regulatory review period, 

while 243 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 (FD&C Act) (21 U.S.C. 

355(i)) became effective: June 13, 2013. 

FDA has verified the applicant’s claim 

that the date the investigational new 

drug application became effective was 

on June 13, 2013. 

2. The date the application was 

initially submitted with respect to the 

human drug product under section 505 

of the FD&C Act: November 9, 2020. 

FDA has verified the applicant’s claim 

that the new drug application (NDA) for 

Kerendia (NDA 215341) was initially 

submitted on November 9, 2020.

Federal Register / Vol. 88, No. 228 / Wednesday, November 29, 2023 / Notices 83417 

3. The date the application was 

approved: July 9, 2021. FDA has verified 

the applicant’s claim that NDA 215341 

was approved on July 9, 2021. 

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 1,597 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 § 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

SUPPLEMENTARY INFORMATION: In 

compliance with 44 U.S.C. 3507, FDA 

has submitted the following proposed 

collection of information to OMB for 

review and clearance. 

State Petitions for Exemption From 

Preemption 

OMB Control Number 0910–0277— 

Extension 

This information collection supports 

FDA regulations. Under section 403A(b) 

of the Federal Food, Drug, and Cosmetic 

Act (FD&C Act) (21 U.S.C. 343–1(b)), 

States may petition FDA for exemption 

from Federal preemption of State food 

labeling and standard-of-identity 

requirements. Section 100.1(c) (21 CFR 

100.1(c)) provides prerequisites a 

petition must satisfy for an exemption 

from preemption. Section 100.1(d) sets 

forth the information a State is required 

to submit in such a petition. The 

petition must be submitted to the 

Dockets Management Staff. The 

information required under § 100.1 

enables FDA to determine whether the 

State food labeling or standard-ofidentity requirement satisfies the 

criteria of section 403A(b) of the FD&C 

Act for granting exemption from Federal 

preemption. 

In the Federal Register of July 31, 

2023 (88 FR 49469), FDA published a 

60-day notice requesting public 

comment on the proposed collection of 

information. Although one comment 

was received, it was not responsive to 

the four information collection topics 

solicited. 

Description of Respondents: The 

respondents to this collection of 

information are State and local 

governments who regulate food labeling 

and standards-of-identity. 

We estimate the burden of this 

collection of information as follows: 

TABLE 1—ESTIMATED ANNUAL REPORTING BURDEN 1

21 CFR section; activity Number of 

respondents 

Number of 

responses per 

respondent 

Total annual 

responses 

Average 

burden per 

response 

Total hours 

100.1; petition for exemption from preemption .................... 1 1 1 40 40 

1There are no capital costs or operating and maintenance costs associated with this collection of information. 

The reporting burden for § 100.1 is 

minimal because petitions for 

exemption from preemption are seldom 

submitted by States. In the next 3 years, 

we estimate that one or fewer petitions 

will be submitted annually. 

Based on a review of the information 

collection since our last request for 

OMB approval, we have made no 

adjustments to our burden estimate. 

Dated: November 24, 2023.
