# SUPPLEMENTARY INFORMATION:

## I. Background

                    In the                     **Federal Register**                     of June 11, 2010 (75 FR 33311), FDA announced the availability of a guidance for industry entitled “Bioequivalence Recommendations for Specific Products,” which explained the process that would be used to make product-specific guidances available to the public on FDA's Web site at                     *https://www.fda.gov/​Drugs/​GuidanceComplianceRegulatoryInformation/​Guidances/​default.htm.*

As described in that guidance, FDA adopted this process to develop and disseminate product-specific guidances and to provide a meaningful opportunity for the public to consider and comment on the guidances. This notice announces the availability of a draft product-specific guidance for generic tiotropium bromide inhalation powder.

                    FDA initially approved new drug application 21395 for SPIRIVA                           ( print page 48826)                        HANDIHALER (tiotropium bromide inhalation powder) in January 2004. We are now issuing draft guidance for industry on, among other things, BE recommendations for generic tiotropium bromide inhalation powder (“Draft Guidance on Tiotropium Bromide”).                

In October 2012, Boehringer Ingelheim, manufacturer of the reference listed drug SPIRIVA HANDIHALER, submitted a citizen petition requesting, among other things, that FDA adopt and apply certain requirements that ensure the safety and efficacy of any proposed generic and follow-on versions of SPIRIVA HANDIHALER under section 505(j) and (b)(2), respectively, of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 355(j) and (b)(2)) (Docket No. FDA-2012-P-1072). FDA is reviewing the issues raised in the petition, and will consider any comments on the draft guidance entitled “Draft Guidance on Tiotropium Bromide” before responding to Boehringer's citizen petition.

This draft guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The draft guidance, when finalized, will represent the current thinking of FDA on, among other things, the design of BE studies to support ANDAs for tiotropium bromide inhalation powder. 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. This guidance is not subject to Executive Order 12866.

## II. Electronic Access

                    Persons with access to the internet may obtain the draft guidance at either                     *https://www.fda.gov/​Drugs/​GuidanceComplianceRegulatoryInformation/​Guidances/​default.htm*                     or                     *https://www.regulations.gov.*

Deputy Commissioner for Policy, Planning, Legislation, and Analysis.
