# SUPPLEMENTARY INFORMATION:

## I. Background

                    In the                     **Federal Register**                     of June 11, 2010 (75 FR 33311), FDA announced the availability of a guidance for industry, “Bioequivalence Recommendations for Specific Products,” which explained the process that would be used to make product-specific BE recommendations available to the public on FDA's Web site at                     *http://www.fda.gov/​Drugs/​GuidanceComplianceRegulatoryInformation/​Guidances/​default.htm*. As described in that guidance, FDA adopted this process as a means to develop and disseminate product-specific BE recommendations and provide a meaningful opportunity for the public to consider and comment on those recommendations. This notice announces the availability of draft BE recommendations for methylphenidate HCl extended-release oral suspension.                

New drug application 202100 for Quillivant XR (methylphenidate HCl) extended-release oral suspension was initially approved by FDA in September 2012. There are no approved ANDAs for this product. FDA is now issuing a draft guidance for industry on BE recommendations for generic methylphenidate HCl extended-release oral suspension (Draft Methylphenidate HCl Oral Suspension BE Recommendations).

In August 2014, Pfizer, Inc., manufacturer of the reference listed drug, Quillivant XR, submitted a citizen petition requesting that FDA establish certain BE requirements for any new drug product that references Quillivant XR and seeks approval by means of demonstrating BE to Quillivant XR (Docket No. FDA-2014-P-1269). FDA is reviewing the issues raised in the 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This draft guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The draft guidance, when finalized, will represent the Agency's current thinking on the design of BE studies to support ANDAs for methylphenidate HCl extended-release oral suspension. It does not create or confer any rights for or on any person and does not operate to bind FDA or the public. An alternative approach may be used if such approach satisfies the requirements of the applicable statutes and regulations.

## II. Comments

                    Interested persons may submit to the Division of Dockets Management (see                     **ADDRESSES**                    ) either electronic or written                           ( print page 77516)                        comments regarding this document. It is only necessary to send one set of comments. Identify comments with the docket number found in brackets in the heading of this document. Received comments may be seen in the Division of Dockets Management between 9 a.m. and 4 p.m., Monday through Friday.                

## III. Electronic Access

                    Persons with access to the Internet may obtain the document at either                     *http://www.fda.gov/​Drugs/​GuidanceComplianceRegulatoryInformation/​Guidances/​default.htm*                     or                     *http://www.regulations.gov*.                

Dated: December 18, 2014.

Associate Commissioner for Policy.
