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 CRESEMBA 
(isavuconazonium sulfate). CRESEMBA is indicated for use in the 
treatment of invasive aspergillosis and invasive mucormycosis. 
Subsequent to this approval, the USPTO received patent term restoration 
applications for CRESEMBA as approved under NDA 207500 (U.S. Patent 
Nos. 6,812,238 and 7,459,561) from Basilea Pharmaceutica International 
Ltd., and the USPTO requested FDA's assistance in determining the 
patents' eligibility for patent term restoration. In a letter dated 
July 28, 2016, FDA advised the USPTO that this human drug product had 
undergone a regulatory review period and that the approval of CRESEMBA 
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 
CRESEMBA is 3,528 days. Of this time, 3,286 days occurred during the 
testing phase of the regulatory review period, while 242 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 U.S.C. 355(i)) became 
effective: July 10, 2005. FDA has verified the applicant's claim that 
July 10, 2005, is the date the investigational new drug application 
(IND) became effective.
    2. The date the application was initially submitted with respect to 
the human drug product under section 505(b) of the FD&C Act: July 8, 
2014. FDA has verified the applicant's claim that the new drug 
application (NDA) for CRESEMBA (NDA 207500) was initially submitted on 
July 8, 2014.
    3. The date the application was approved: March 6, 2015. FDA has 
verified the applicant's claim that NDA 207500 was approved on March 6, 
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 
based on NDA 207500, this applicant seeks 5 years or 1,264 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 
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), Food and Drug 
Administration, 5630 Fishers Lane, Rm. 1061, Rockville, MD 20852.
