Waiver of In Vivo Bioavailability and Bioequivalence Studies for Immediate-Release Solid Oral Dosage Forms Based on a Biopharmaceutics Classification System; Guidance for Industry; Availability, 61011-61013 [2017-27786]

Download as PDF Federal Register / Vol. 82, No. 246 / Tuesday, December 26, 2017 / Notices 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 ZYKADIA (ceritinib). ZYKADIA is indicated for the treatment of patients with anaplastic lymphoma kinase-positive metastatic non-small cell lung cancer who have progressed on or are intolerant to crizotinib. This indication is approved under accelerated approval based on tumor response rate and duration of response. An improvement in survival or disease-related symptoms has not been established. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials. Subsequent to this approval, the USPTO received patent term restoration applications for ZYKADIA (U.S. Patent Nos. 7,964,592 from Novartis AG and and 8,377,921 from IRM LLC), and the USPTO requested FDA’s assistance in determining the patents’ eligibility for patent term restoration. In a letter dated October 15, 2015, FDA advised the USPTO that this human drug product had undergone a regulatory review period and that the approval of ZYKADIA represented the first permitted commercial marketing or use of the product. Thereafter, the USPTO requested that FDA determine the product’s regulatory review period. ethrower on DSK3G9T082PROD with NOTICES II. Determination of Regulatory Review Period FDA has determined that the applicable regulatory review period for ZYKADIA is 1,271 days. Of this time, 1,144 days occurred during the testing phase of the regulatory review period, while 127 days occurred during the approval phase. These periods of time were derived from the following dates: VerDate Sep<11>2014 20:21 Dec 22, 2017 Jkt 244001 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 7, 2010. FDA has verified the applicants’ claims that November 7, 2010, is the date the investigational new drug application 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: December 24, 2013. FDA has verified the applicants’ claims that the new drug application (NDA) for ZYKADIA (NDA 205755) was initially submitted on December 24, 2013. 3. The date the application was approved: April 29, 2014. FDA has verified the applicants’ claims that NDA 205755 was approved on April 29, 2014. 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 their applications for patent extension, these applicants seek 472 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 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

FDA is announcing the availability of a guidance for industry
entitled ``Waiver of In Vivo Bioavailability and Bioequivalence Studies
for Immediate-Release Solid Oral Dosage Forms Based on a
Biopharmaceutics Classification System.'' This guidance provides
recommendations for sponsors of INDs, and applicants who submit NDAs,
ANDAs, and supplements to these applications for IR solid oral dosage
forms, and who wish to request a waiver of an in vivo BA and/or BE
study requirement. These recommendations are intended to apply to
waivers requested during the IND period and the NDA stage or for ANDAs,
i.e.: (1) Subsequent in vivo BA or BE studies of formulations after the
initial establishment of the in vivo BA of IR solid oral dosage forms
during the IND period, and (2) in vivo BE studies of IR solid oral
dosage forms in NDAs, ANDAs, and supplements to these applications.
This guidance finalizes the guidance for industry on Waiver of In
Vivo Bioavailability and Bioequivalence Studies for Immediate-Release
Solid Oral Dosage Forms Based on a Biopharmaceutics Classification
System, published on May 6, 2015 (80 FR 26058), and explains when
biowaivers can be requested for IR solid oral dosage forms based on an
approach termed the Biopharmaceutics Classification System (BCS). While
many positive comments were received on the published draft guidance,
several requests were made for additional clarification regarding the
biowaivers for BCS class 3 drug substances, and specific issues
pertaining to dissolution and permeability categories. In response,
this guidance includes biowaiver extension to BCS class 3 drug
products, and additional modifications, such as criteria for high
permeability and high solubility.
This guidance is being issued consistent with FDA's good guidance
practices regulation (21 CFR 10.115). The guidance represents the
current thinking of FDA on Waiver of In Vivo Bioavailability and
Bioequivalence Studies for Immediate-Release Solid Oral Dosage Forms
Based on a Biopharmaceutics Classification System. It does not
establish any rights for any person and is not binding on FDA or the
public. You can use an alternative approach if it satisfies the
requirements of the applicable statutes and regulations.

II. Paperwork Reduction Act of 1995

This guidance refers to previously approved collections of
information that are subject to review by the Office of Management and
Budget (OMB) under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-
3520). The collections of information in part 314 (21 CFR part 314),
including Sec. Sec. 314.50 and 314.94, have been approved under OMB
control number 0910-0001.
