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'' that explained 
the process that would be used to make product-specific guidances 
available to the public on FDA's website at https://www.fda.gov/drugs/guidance-compliance-regulatory-information/guidances-drugs.
    As described in that guidance, FDA adopted this process as a means 
to develop and disseminate product-specific guidances and provide a 
meaningful opportunity for the public to consider and comment on those 
guidances. This notice announces the availability of a revised draft 
product-specific guidance on generic iron sucrose intravenous 
injectable.
    FDA initially approved new drug application (NDA) 021135 VENOFER 
(iron sucrose intravenous injectable) in November 2000 and NDA 205109 
VELPHORO (sucroferric oxyhydroxide oral tablet) in November 2013.\1\ In 
April 2016, Foley & Hoag LLP, on behalf of Vifor Fresenius Medical Care 
Renal Pharma France, holder of NDA 205109 VELPHORO, submitted a citizen 
petition requesting, among other things, that FDA grant five-year new 
chemical entity exclusivity pursuant to sections 505(j)(5)(F)(ii) and 
505(c)(3)(E)(ii) of the Federal Food, Drug, and Cosmetic Act to 
VELPHORO and stay the acceptance, receipt, filing, review, and/or 
approval of any ANDAs or 505(b)(2) applications referencing VELPHORO 
while FDA considers VELPHORO's new chemical entity exclusivity (Docket 
No. FDA-2016-P-1163, available at https://www.regulations.gov). On May 
26, 2021, FDA issued a response to that citizen petition noting that 
the active ingredient of multiple iron products, including VELPHORO and 
VENOFER, is ferric oxyhydroxide.2 3
---------------------------------------------------------------------------

    \1\ The active ingredients were identified as iron sucrose and 
sucroferric oxyhydroxide, respectively, at the time of approval of 
these NDAs.
    \2\ See Letter to Areta Kupchyk, Foley Hoag LLP, from Patrizia 
Cavazzoni, M.D., Acting Director, Center for Drug Evaluation and 
Research, Docket No. FDA-2016-P-1163 (May 26, 2021).
    \3\ In March 2005, Sonnenschein, Nath & Rosenthal LLP submitted 
a citizen petition requesting, among other things, that FDA withhold 
approval of any ANDA or section 505(b)(2) application that 
references VENOFER unless certain conditions are satisfied, 
including conditions related to demonstrating BE. (Docket No. FDA-
2005-P-0319). The issues raised by that petition are under review by 
the Agency, and FDA has not made a final decision on those issues.
---------------------------------------------------------------------------

    In August 2021, Sidley Austin LLP, on behalf of Vifor 
(International) Inc., Switzerland (Vifor),\4\ submitted a citizen 
petition requesting that FDA refrain from taking several actions, 
including changing the product label or labeling for VENOFER, modifying 
the existing product-specific guidance for VENOFER, and/or changing the 
established name of VENOFER from iron sucrose to ferric oxyhydroxide 
(Docket No. FDA-2021-P-0893, available https://www.regulations.gov). In 
September 2021, FDA issued a revised draft product-specific guidance 
for industry on generic ferric oxyhydroxide intravenous injectable and 
stated that FDA is reviewing the issues raised in the petition and will 
consider any comments on the draft guidance before responding to the 
petition.\5\ In July 2024, FDA issued a memo to the Docket No. FDA-
2021-P-0893 stating that FDA is reevaluating its determination that the 
active ingredient of the iron products subject to the May 26, 2021 
citizen petition response is ferric oxyhydroxide. We are now issuing a 
revised draft guidance for industry on generic iron sucrose intravenous 
injectable. FDA is separately responding to Vifor's citizen petition 
(FDA-2021-P-0893).
---------------------------------------------------------------------------

    \4\ Vifor (International) Inc., Switzerland is a Swiss 
pharmaceutical company, which is the drug master file holder for 
iron sucrose and the owner of the VENOFER trademark and logo. Vifor 
licenses VENOFER in the United States to American Regent, Inc., the 
holder of the NDA for VENOFER. The NDA holder for VELPHORO is Vifor 
Fresenius Medical Care Renal Pharma France, which is a joint venture 
established by Vifor's parent company and Fresenius Medical Care.
    \5\ 86 FR 51898 (September 17, 2021).
---------------------------------------------------------------------------

    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 ``Draft 
Guidance on Iron Sucrose.'' 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.
    As we develop final guidance on this topic, FDA will consider 
comments on costs or cost savings the guidance may generate, relevant 
for Executive Order 14192.

II. Paperwork Reduction Act of 1995
