# SUPPLEMENTARY INFORMATION:

                    In the                     **Federal Register**                     of December 20, 2017, FDA published a notice of availability with a 30-day comment period to request comments on the draft guidance for industry entitled “Clarification of Orphan Designation of Drugs and Biologics for Pediatric Subpopulations of Common Diseases.”                

                    This draft guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The draft guidance, when finalized, will represent the current thinking of FDA on orphan designation of drugs and biologics for pediatric subpopulations of common diseases. It does not establish any rights for any person and is not binding on FDA or the public. You can                           ( print page 1620)                        use an alternative approach if it satisfies the requirements of the applicable statutes and regulations. This draft guidance is not subject to Executive Order 12866.                

Based on public interest in the draft guidance, FDA is extending the comment period for the notice of availability for 30 days, until February 28, 2018. The Agency believes that a 30-day extension allows adequate time for interested persons to submit comments without significantly delaying guidance on these important issues.

Dated: January 8, 2018.

Leslie Kux,

Associate Commissioner for Policy.
