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 


khammond on DSKJM1Z7X2PROD with NOTICES
88398 Federal Register / Vol. 88, No. 244 / Thursday, December 21, 2023 / Notices 

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, LYBALVI 

(olanzapine and samidorphan), which is 

indicated for the treatment of: 

• Schizophrenia in adults 

• Bipolar I disorder in adults 

Æ Acute treatment of manic or mixed 

episodes as monotherapy and as 

adjunct to lithium or valproate 

Æ Maintenance monotherapy treatment 

Subsequent to this approval, the 

USPTO received patent term restoration 

applications for LYBALVI (U.S. Patent 

Nos. 7,262,298; 9,119,848; 9,126,977; 

10,300,054; and 10,716,785) from 

Alkermes 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 LYBALVI 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 

LYBALVI is 4,564 days. Of this time, 

4,003 days occurred during the testing 

phase of the regulatory review period, 

while 561 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: November 30, 

2008. FDA has verified the applicant’s 

claim that the date the investigational 

new drug application became effective 

was on November 30, 2008. 

2. The date the application was 

initially submitted with respect to the 

human drug product under section 505 

of the FD&C Act: November 15, 2019. 

FDA has verified the applicant’s claim 

that the new drug application (NDA) for 

LYBALVI (NDA 213378) was initially 

submitted on November 15, 2019. 

3. The date the application was 

approved: May 28, 2021. FDA has 

verified the applicant’s claim that NDA 

213378 was approved on May 28, 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 applications for patent extension, 

this applicant seeks 311 days, 646 days, 

1,325 days, 1,328 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 § 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. 

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),
