`In Re: Patent Term Extension
`Application for
`U.S. Patent No. 6,599,498
`
`lCl .- 9 2013
`
`NOTICE OF FINAL DETERMINATION
`
`A determination has been made that U.S. Patent No. 6,599,498, claims of which cover the human
`drug product FERAHEME® (ferumoxytol), is eligible for patent term extension under 35 U.S.C.
`§ 156. The period of extension has been determined to be 1,209 days.
`
`A single request for reconsideration of this final determination as to the length of extension of the
`term of the patent may be made if filed within one month of the date of this notice. Extensions
`of time under 37 CFR § l .136(a) are not applicable to this time period. In the absence of a
`request for reconsideration, the Director will issue a certificate of extension, under seal, for a
`period of 1,209 days.
`
`The period of extension, if calculated using the Food and Drug Administration determination of
`the length of the regulatory review period published in the Federal Register of May 4, 2012 (77
`. Fed. Reg. 26557), would be 1,362 days. Under 35 U.S.C. § 156(c):
`
`Period of Extension
`
`=
`
`RRP - PGRRP - DD - 'Ii (TP - PGTP) 1
`3,680 - 1,516 - 0 - Yi (3,120 - 1,516)
`1,362 (years)
`
`Since the regulatory review period began June 5, 1999, before the patent issued (July 29, 2003),
`only that portion of the regulatory review period occurring after the date the patent issued has been
`considered in the above determination of the length of the extension period 3 5 U .S.C. § 156( c ).
`(From June 5, 1999, to and including July 29, 2003, is 1,516 days; this period is subtracted from
`the number of days occurring in the testing phase according to the FDA determination of the
`length of the regulatory review period.) No determination of a lack of due diligence under 35
`U.S.C. § 156(c)(l) was made.
`
`However, the 14 year exception of 35 U.S.C. § 156(c)(3) operates to limit the term of the
`
`1 Consistent with 35 U.S.C. § 156(c), "RRP" is the total number of days in the regulatory
`review period, "PGRRP" is the number of days of the RRP which were on and before the date on
`which the patent issued, "DD" is the number of days of the RRP that the applicant did not act
`with due diligence, "TP" is the testing phase period described in paragraphs (l)(B)(i), (2)(B)(i),
`(3)(B)(i), ( 4)(B)(i), and (5)(B)(i) of subsection (g) of 35 U.S.C. § 156, and "PGTP" is the number
`of days of the TP which were on and before the date on which the patent issued, wherein half
`days are ignored for purposes of the subtraction of Yi (TP - PGTP).

`
`extension in the present situation, because it provides that the period remaining in the term of the
`patent measured from the date of approval of the approved product plus any patent term
`extension cannot exceed fourteen years. The period of extension calculated above, 1,362, would
`extend the patent from March 8, 2020, to November 30, 2023, which is beyond the 14-year limit
`(the approval date is June 30, 2009, thus, the 14 year limit is June 30, 2023). The period of
`extension is thus limited to June 30, 2023, by operation of 35 U.S.C. § 156(c)(3). Accordingly,
`the period of extension is the number of days to extend the term of the patent from its original
`expiration date, March 8, 2020, to and including June 30, 2023, or 1,209 days.
`
`The limitations of 35 U.S.C. 156(g)(6) do not operate to further reduce the period of extension
`determined above.

`
`Dear Director Kappas:
`
`This is in regard to the patent term extension application for U.S. Patent No. 6,599,498 filed by
`AMAG Pharmaceuticals, Inc., under 35 U.S.C. § 156. The patent claims FERAHEME, which
`was assigned new drug application 22-180.
`
`In the May 4, 2012, issue of the Federal Register (77 Fed. Reg. 26557), the Food and Drug
`Administration published its determination of this product's regulatory review period, as required
`under 35 U.S.C. § 156(d)(2)(A). The notice provided that on or before October 31, 2012, 180
`days after the publication.of the determination, any interested person could file a petition with
`FDA under 35 U.S.C. § 156(d)(2)(B)(i) for a determination of whether the patent term extension
`applicant acted with due diligence during the regulatory review period.
`
`The 180-day period for filing a due diligence petition pursuant to this notice has expired and
`FDA has received no such petition. Therefore, FDA considers the regulatory review period
`determination to be final.
`
`Please let me know if we can provide further assistance.
`
`Sincerely yours,
`
`ra.~

`
`marketed. Under these acts, a product's
`regulatory review period forms the basis
`for determining the amount of extension
`an applicant may receive.
`A regulatory review period consists of
`two periods of time: A testing phase and
`an approval phase. For animal drug
`products, the testing phase begins on
`the earlier date when either a major
`environmental effects test was initiated
`for the drug or when an exemption
`under section 512(j) of the Federal Food,
`Drug, and Cosmetic Act (21 U.S.C.
`360b(j)) became effective and runs until
`the approval phase begins. The approval
`phase starts with the initial submission
`of an application to market the animal
`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 Patents and
`Trademarks 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 ofthe
`length of a regulatory review period for
`an animal drug product will include all
`of the testing phase and approval phase
`as specified in 35 U.S.C. 156(g)(4)[B).
`FDA approved for marketing the
`animal drug product EQUIDONE GEL
`(domperidone). EQUIDONE GEL is
`indicated for prevention of fescue
`toxicosis in periparturient mares.
`Subsequent to this approval, the Patent
`and Trademark Office received a patent
`term restoration application for
`EQUIDONE GEL (U.S. Patent No.
`5,372,818) from Dechra, Ltd., and the
`Patent and Trademark Office requested
`FDA's assistance in determining this
`patent's eligibility for patent term
`restoration. In a letter dated April 26,
`2011, FDA advised the Patent and
`Trademark Office that this animal drug
`product had undergone a regulatory
`review period and that the approval of
`EQUIDONE GEL represented the first
`permitted commercial marketing or use
`of the product. Thereafter, the Patent
`and Trademark Office requested that
`FDA determine the product's regulatory
`review period.
`FDA has determined that the
`applicable regulatory review period for
`EQUIDONE GEL is 6,378 days. Of this
`time, 6,336 days occurred during the
`testing phase of the regulatory review
`period, while 42 days occurred during
`the approval phase. These periods of
`time were derived from the following
`dates:
`1. The date an exemption under
`section 512(j) of the Federal Food, Drug,
`and Cosmetic Act (21 U.S.C. 36Db(j))
`became effective: March 26, 1993.'The
`
`applicant claims February 24, 1992, as
`the date the investigational new animal
`drug application (IND) became effective.
`However, the date that a major health or
`environmental effects test is begun or
`the date on which the Agency
`acknowledges the filing of a notice of
`claimed investigational exemption
`(NCIE) for a new animal drug,
`whichever is earlier, is the effective date
`for the IND. According to FDA records,
`the applicant's first submission of an
`NCIE was March 26, 1993, which is the
`effective date for the IND.
`2. The date the application was
`initially submitted with respect to the
`animal drug product under section 512
`of the Federal Food, Drug, and Cosmetic
`Act: July 30, 2010. The applicant claims
`July 27, 2010, as the date the new
`animal drug application (NADA) for
`EQUIDONE GEL (NADA 141-314) was
`initially submitted. However, a review
`of FDA records reveals that the date of
`FDA's official acknowledgement letter
`assigning a number to NADA 141-314
`was July 30, 2010, which is considered
`to be the initially submitted date for
`NADA 141-314.
`3. The date the application was
`approved: September 9, 2010. FDA has
`verified the applicant's claim that
`NADA 141-314 was approved on
`September 9, 2010.
`This determination of the regulatory
`review period establishes the maximum
`potential length of a patent extension.
`However, the U.S. Patent and
`Trademark Office applies several
`statutory limitations in its calculations
`of the actual period for patent extension.
`In its application for patent extension,
`this applicant seeks 5 years of patent
`term extension.
`Anyone with knowledge that any of
`the dates as published are incorrect may
`submit to the Division of Dockets
`Management (see ADDRESSES) either
`written or electronic comments and ask
`for a redetermination by July 3, 2012.
`Furthermore, any interested person may
`petition FDA for a determination
`regarding whether the applicant for
`extension acted with due diligence
`during the regulatory review period by
`October 31, 2012. To meet its burden,
`the petition must contain sufficient facts
`to merit an FDA investigation. (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.
`Interested persons may submit to the
`Division of Dockets Management (see
`ADDRESSES) electronic or written
`comments and written petitions. It is
`only necessary to send one set of
`comments. However, if you submit a
`written petition, you must submit three
`copies of the petition. Identify
`
`comments with the docket number
`found in brackets in the heading of this

`Management between 9 a.m. and 4 p.m.,
`Monday through Friday.

`
`review by FDA before the item was
`marketed. Under these acts, a product's
`regulatory review period forms the basis
`for determining the amount of extension
`an applicant may receive.
`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 Patents and Trademarks 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 recently approved for marketing
`the human drug product FERAHEME
`(ferumoxytol). FERAHEME is indicated
`for the treatment of iron deficiency
`anemia in adult patients with chronic
`kidney disease. Subsequent to this
`approval, the Patent and Trademark
`Office received a patent term restoration
`application for FERAHEME (U.S. Patent
`No. 6,599,498) from AMAG
`Pharmaceuticals, Inc., and the Patent
`and Trademark Office requested FDA's
`assistance in determining this patent's
`eligibility for patent term restoration. In
`a letter dated May 2, 2011, FDA advised
`the Patent and Trademark Office that
`this human drug product had undergone
`a regulatory review period and that the
`approval of FERAHEME represented the
`first permitted commercial marketing or
`use of the product. Thereafter, the
`Patent and Trademark Office requested
`that FDA determine the product's
`regulatory review period.
`FDA has determined that the
`applicable regulatory review period for
`FERAHEME is 3,680 days. Of this time,
`3,120 days occurred during the testing
`phase of the regulatory review period,
`while 560 days occurred during the
`approval phase. These periods of time
`were derived from the following dates:
`1. The date an exemption under
`section 505(i) of the Federal Food, Drug,
`and Cosmetic Act (the FD&C Act) (21
`U.S.C. 355(i)) became effective: June 5,
`1999. The applicant claims June 4, 1999,
`as the date the investigational new drug
`application (IND) became effective.
`
`However, FDA records indicate that the
`IND effective date was June 5, 1999,
`which was 30 days after FDA receipt of
`the IND.
`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 19,
`2007. The applicant claims December
`18, 2007, as the date the new drug
`application (NDA) for FERAHEME
`(NDA 22-180) was initially submitted.
`However, FDA records indicate that
`NDA 22-180 was submitted on
`. December 19, 2007.
`3. The date the application was
`approved: June 30, 2009. FDA has
`verified the applicant's claim that NDA
`22-180 was approved on June 30, 2009.
`This determination of the regulatory
`review period establishes the maximum
`potential length of a patent extension.
`However, the U.S. Patent and
`Trademark Office applies several
`statutory limitations in its calculations
`of the actual period for patent extension.
`In its application for patent extension,
`this applicant seeks 1,209 days of patent
`term extension.
`Anyone with knowledge that any of
`the dates as published are incorrect may
`submit to the Division of Dockets
`Management (see ADDRESSES) either
`electronic or written comments and ask
`for a redetermination by July 3, 2012.
`Furthermore, any interested person may
`petition FDA for a determination
`regarding whether the applicant for
`extension
