  •                                UNITED STATES DISTRICT COURT
    FOR THE DISTRICT OF COLUMBIA
    IPSEN BIOPHARMACEUTICALS, INC.,
    Plaintiff,
    v.
    No. 16-cv-2372 (DLF)
    ALEX M. AZAR II, in his official capacity as
    Secretary of Health and Human Services, et
    al.,
    Defendants.
    MEMORANDUM OPINION
    Ipsen Biopharmaceuticals, Inc. (Ipsen) brought this lawsuit in 2016 against the Secretary
    of Health and Human Services 1 under the Administrative Procedure Act, 5 U.S.C. § 551 et seq.
    (the APA). Ipsen alleges that the Center for Medicare and Medicaid Services (CMS), a sub-
    agency within the Department of Health and Human Services (HHS), interpreted Title XIX of
    the Social Security Act, 42 U.S.C. § 1396 et seq. (the Medicaid Act), in a manner that was
    arbitrary, capricious, or not in accordance with law. Before the Court are Ipsen’s Renewed
    Motion for Summary Judgment, Dkt. 33, and the Secretary’s Renewed Cross-Motion for
    Summary Judgment, Dkt. 34. Because the Court concludes that CMS’s interpretation was
    neither contrary to law nor arbitrary and capricious, the Court will deny Ipsen’s Renewed Motion
    for Summary Judgment and grant the Secretary’s Renewed Cross-Motion for Summary
    Judgment.
    1
    Sylvia Burwell was Secretary of Health and Human Services when Ipsen filed its complaint,
    but Alex M. Azar II has since taken that position and is automatically substituted as the
    defendant in this case under Rule 25(d) of the Federal Rules of Civil Procedure.
    I.     BACKGROUND
    A.      Statutory and Regulatory Framework
    This case implicates the relationship between two federal statutes administered by
    sub-agencies of HHS: the Medicaid Act, which is administered by CMS, and the Food, Drug,
    and Cosmetic Act, 21 U.S.C. § 301 et seq. (the FDCA), which is administered by the Food and
    Drug Administration (FDA). Ipsen claims that certain provisions of the FDCA render its product
    a new drug for purposes of calculating its rebate obligations under the Medicaid Act. The
    relevant statutory and regulatory provisions are as follows.
    1.      Medicaid Act
    Congress created Medicaid in 1965 when it added Title XIX to the Social Security Act.
    Pharm. Research & Mfrs. of Am. v. Walsh, 
    538 U.S. 644
    , 650 (2003). “Medicaid, as everyone
    knows, is a cooperative state-federal program designed to provide medical assistance to poor
    people.” Indiana Family & Soc. Servs. Admin. v. Thompson, 
    286 F.3d 476
    , 477 (7th Cir. 2002).
    The program operates by providing federal financial assistance to states that reimburse certain
    medical costs for the needy. Pharm. 
    Research, 538 U.S. at 650
    .
    The Medicaid Act sets forth the circumstances under which drug manufacturers may
    obtain Medicaid coverage for their drug products. Principally, to obtain coverage for any of its
    drugs, “the manufacturer must have entered into and have in effect a rebate agreement . . . with
    the Secretary.” 42 U.S.C. § 1396r-8(a)(1). Under these rebate agreements, drug manufacturers
    agree to pay rebates to the states to help the states cover the costs of providing Medicaid
    coverage for the manufacturer’s drugs.
    Id. § 1396r-8(b)(1)(B).
    The amount of the rebate that manufacturers must pay is established by statute and
    contains two components: the basic rebate and the additional rebate.
    Id. § 1396r-8(c)(1),
    (c)(2).
    2
    At issue in this case is the additional rebate. For the type of drug in question, the additional
    rebate consists of the difference between the average manufacturer price of the drug for that
    rebate period and the average manufacturer price of the drug, adjusted for inflation, for “the first
    full calendar quarter after the day on which the drug was first marketed,” multiplied by the total
    number of units of the drug for which the state made payment over the course of a given rebate
    period.
    Id. § 1396r-8(c)(2)(A),
    (c)(2)(B). The “average manufacturer price” (AMP) for the “first
    full calendar quarter” in which the drug is marketed is known as the “base date AMP.”
    To put that in layman’s terms, the additional rebate fully compensates the state for any
    amount, in excess of the inflation rate, by which the manufacturer increases the price of a drug
    after it first comes to market. The “base date AMP” is important because it provides the baseline
    from which a drug manufacturer’s price increases, and therefore its rebate obligations to the
    states, are calculated. A higher “base date AMP” means lower rebate obligations for the
    manufacturer, because the net increase in the price of the drug is correspondingly lower. To the
    extent that manufacturers increase the prices of their drugs over time, a later-in-time base date
    will correspond to a higher “base date AMP,” and thus a lower rebate obligation.
    Various definitions contained in the Medicaid Act bear on the statutory question at issue
    here. First, the Medicaid rebate requirement applies independently to each “covered outpatient
    drug,” 42 U.S.C. § 1396r-8(a), and a “covered outpatient drug” is defined, as relevant here, as “a
    drug . . . which is approved for safety and effectiveness as a prescription drug under section 505
    or 507 of the Federal Food, Drug, and Cosmetic Act or which is approved under section 505(j) of
    such Act,” 42 U.S.C. § 1396r-8(k)(2).
    Second, the additional rebate provision described above applies specifically to “single
    source drug[s]” and “innovator multiple source drug[s].” 42 U.S.C. § 1396r-8(c)(2)(A). As
    3
    relevant here, the Medicaid Act defines “single source drug” as “a covered outpatient drug . . .
    which is produced or distributed under a new drug application approved by the Food and Drug
    Administration,”
    id. § 1396r-
    8(k)(7)(iv), 
    and an “innovator multiple source drug” as “a multiple
    source drug that is marketed under a new drug application approved by the Food and Drug
    Administration,”
    id.
    § 1396r-
    8(k)(7)(ii). 
    The Medicaid Act’s implementing regulations further
    specify that an “innovator multiple source drug” is a “multiple source drug that was originally
    marketed under an original new drug application (NDA) approved by FDA,” and that a “single
    source drug” is “a covered outpatient drug that is produced or distributed under an original NDA
    approved by FDA and has an approved NDA number issued by FDA.” 42 C.F.R. § 447.502.
    2.      Food, Drug, and Cosmetic Act
    The FDCA sets forth various requirements for the approval of new drugs. The Act
    defines “new drug” in relevant part to mean “[a]ny drug . . . the composition of which is such
    that such drug is not generally recognized, among experts qualified by scientific training and
    experience to evaluate the safety and effectiveness of drugs, as safe and effective for use under
    the conditions prescribed, recommended, or suggested in the labeling thereof.” 21 U.S.C.
    § 321(p). It then imposes a general requirement that “[n]o person shall introduce or deliver for
    introduction into interstate commerce any new drug, unless an approval of an application filed
    pursuant to subsection (b) or (j) is effective with respect to such drug.”
    Id. § 355(a).
    2
    Section 505(b) provides that persons seeking approval of such new drugs “may file with
    the Secretary an application with respect to any drug subject to the provisions of subsection (a).”
    Id. § 355(b)(1).
    Any such application must contain various pieces of information specified by
    2
    Section 505(j) of the FDCA refers to the process for filing an abbreviated new drug application
    (aNDA), which applies to generic drugs. See 21 U.S.C. § 355(j). Because the drug product at
    issue here is not generic, the statutory provisions regarding aNDAs are not relevant to this case.
    4
    statute, including, for example, “full reports of investigations which have been made to show
    whether or not such drug is safe for use and whether such drug is effective in use,” “a full list of
    the articles used as components of such drug,” and “a full statement of the composition of such
    drug.”
    Id. § 355(b)(1)(A),
    (b)(1)(B), (b)(1)(C).
    An application submitted under section 505(b)(1) of the FDCA is referred to as a “new
    drug application” (NDA). 21 C.F.R. § 314.3. The FDCA’s implementing regulations provide, in
    21 C.F.R. § 314.50, extensive requirements beyond those imposed in the statute itself that the
    NDA must meet to obtain FDA approval. See
    id. The regulations
    also define “new drug
    application” as “the application described under § 314.50, including all amendments and
    supplements to the application.”
    Id. § 314.3.
    The implementing regulations establish a separate process that applies when a
    manufacturer wishes to make “[s]upplements and other changes to an approved NDA.” 21
    C.F.R. § 314.70. Under that process, “the applicant must notify FDA about each change in each
    condition established in an approved NDA beyond the variations already provided for in the
    NDA,” and must “describe the change fully.”
    Id. § 314.70(a).
    Certain “major changes” to an approved NDA require the manufacturer to submit a
    “supplemental new drug application” (sNDA) and obtain FDA’s approval of that sNDA “prior to
    distribution of the product made using the change.”
    Id. § 314.70(b)
    . 
    Those “major changes” are
    defined as “any change in the drug substance, drug product, production process, quality controls,
    equipment, or facilities that has a substantial potential to have an adverse effect on the identity,
    strength, quality, purity, or potency of the drug product as these factors may relate to the safety
    or effectiveness of the drug product.”
    Id. “Major changes”
    include things like “[c]hanges that
    may affect drug substance or drug product sterility assurance,”
    id. § 314.70(b)(2)(iii),
    or
    5
    “[c]hanges in a drug product container closure system that controls the drug product delivered to
    a patient,”
    id. § 314.70(b)(2)(vi).
    “Moderate changes,” defined as changes with a “moderate potential to have an adverse
    effect on the identity, strength, quality, purity, or potency of the drug product as these factors
    may relate to the safety or effectiveness of the drug product,” also require submission of a
    sNDA. But the manufacturer need only submit the application “at least 30 days prior to
    distribution,” and need not obtain FDA’s approval prior to marketing “the drug product made
    using the change.”
    Id. § 314.70(c).
    “Minor changes” do not require submission of a sNDA at
    all; the manufacturer need only document them in its next annual report.
    Id. § 314.70(d).
    B.      Factual Background
    Ipsen sells Somatuline Depot (Somatuline), an injectable drug product available in three
    strengths (60 mg, 90 mg, and 120 mg). Dkt. 1 (Compl.) ¶ 40; Administrative Record (A.R.) 35.
    Ipsen received FDA approval of its NDA for Somatuline on August 30, 2007. Compl. ¶ 40; see
    A.R. 35. The FDA approved Somatuline for the treatment of acromegaly, a condition involving
    excessive growth of the hands, feet, and face as a result of excessive growth hormone production
    during adulthood. A.R. 35; Compl. ¶ 41.
    Since 2007, Ipsen has supplemented its NDA for Somatuline 16 times. See U.S. Food &
    Drug Administration, Drugs@FDA: FDA Approved Drug Products: Somatuline Depot,
    https://www.accessdata.fda.gov/scripts/cder/daf/index.cfm?event=overview.process&ApplNo=0
    22074 (last accessed May 14, 2020) (listing sNDA approval dates for Somatuline). The changes
    described in these sNDAs range from changes to Somatuline’s dosing regimen, to its
    manufacturing process, to its efficacy for new indications, to its labeling. See
    id. 6 Two
    of these sNDAs are at issue in this case. First, on October 28, 2014, the FDA
    approved a sNDA for Somatuline that “propose[d] changes to the drug substance and drug
    product manufacturing processes, and to the drug product container closure system, which
    include[d] addition of a sharps protection system to the syringe to help prevent needle stick
    injury after use.” A.R. 40. The sNDA also proposed changes that would harmonize the syringe
    dimensions for the three dosage strengths of Somatuline, as well as corresponding changes to the
    labeling and the healthcare provider instructions for use. Id.; Compl. ¶ 44.
    Second, on December 16, 2014, the FDA approved another sNDA for Somatuline, this
    time “for a new indication for the treatment of patients with unresectable, well- or
    moderately-differentiated, locally advanced or metastatic gastroenteropancreatic neuroendocrine
    tumors (GEP-NETs) to improve progression-free survival.” A.R. 76. Ipsen claims that it spent
    $80 million conducting efficacy trials for this new indication. Compl. ¶ 47. Somatuline was the
    first drug approved by FDA for this indication, which provides a novel therapy for certain cancer
    patients.
    Id. ¶ 48.
    FDA granted Ipsen three years of exclusive marketing privileges in light of
    the clinical data that Ipsen had produced in support of this new indication.
    Id. ¶ 49.
    On January 7, 2015, Ipsen sent CMS a letter indicating its intent to establish an
    independent base date AMP for purposes of its Medicaid rebate obligations. A.R. 1. Ipsen’s
    letter informed CMS that Ipsen was “poised to launch” a new drug product, in three strengths,
    that it planned to call Somatuline Depot with Enhanced Device (Somatuline ED), and argued that
    the three strengths of Somatuline ED “should be considered ‘new products’ entitled to baseline
    AMPs separate and distinct from those” of the original Somatuline drug.
    Id. In support
    of this argument, Ipsen explained that “Somatuline ED has two separate FDA
    approvals (supplemental NDAs) distinct from the NDA under which Somatuline [Depot] came to
    7
    market (one for the new device and a second for the new indication).” A.R. 3. Ipsen noted that
    “[t]hese supplemental applications required independent investment, analysis and approval of the
    delivery mechanism and of the additional indication as well as other changes to the original
    product.”
    Id. Finally, the
    letter informed CMS that Ipsen intended to begin calculating its
    Medicaid rebate obligations for Somatuline ED based on “new baseline AMPs in the first full
    quarter following launch, likely the second quarter of 2015,” and that Ipsen would “proceed with
    this approach absent CMS instruction to the contrary.”
    Id. 4. CMS
    responded on July 2, 2015, by an email from Wendy Tuttle, a Health Insurance
    Specialist with CMS’s Pharmacy Division. A.R. 6–7. Tuttle acknowledged the various
    enhancements that Ipsen had made to Somatuline, but concluded that “these factors do not meet
    the criteria for the establishment of new base date AMPs for the three strengths of Somatuline
    ED.”
    Id. 6. She
    explained that “[s]ections 1927(c)(2)(A) and (B) of the [Medicaid Act] specify
    that the baseline data is established for each dosage form and strength of the drug.”
    Id. (emphasis in
    original). Accordingly, Tuttle rejected the argument that the Somatuline ED
    products approved under the two sNDAs discussed above should have their own base date
    AMPs, “because the final dosage form and strengths of each have remained the same.”
    Id. “Upon our
    review of the information listed with FDA for the three strengths of Somatuline
    Depot, which are all approved under the same NDA number 022074,” she concluded, “we
    believe that the baseline information for each strength of Somatuline ED should be the same as
    the baseline data for the correlating strength of the original Somatuline Depot.”
    Id. On September
    21, 2015, Ipsen’s lawyers wrote to the General Counsel of HHS,
    requesting a meeting to discuss Ipsen’s “entitlement” to unique base date AMPs for its
    Somatuline ED products. A.R. 9. The letter first noted that Ipsen had “conducted extensive and
    8
    costly research to support significant improvements to its Somatuline products.”
    Id. 10. It
    then
    argued that CMS’s determination that Ipsen was not entitled to unique base date AMPs for
    Somatuline ED violated the Medicaid Act because Somatuline ED constituted a distinct “covered
    outpatient drug” under that statute.
    Id. 11–20. Specifically,
    Ipsen argued that the definition of
    “covered outpatient drug” in section 1927 of the Medicaid Act specifically referenced the
    FDCA’s framework for the approval of new drugs,
    id. 12–14, and
    that Somatuline ED
    constituted a “new drug” under that framework,
    id. 14–20. Accordingly,
    the letter concluded,
    “CMS . . . should reconsider its decision reflected in the July 2, 2015 email and should approve
    Ipsen’s request to establish new base date AMPs for its Somatuline ED product.”
    Id. 21. CMS
    responded by a letter dated August 3, 2016 from Dr. John Coster, Director of
    CMS’s Pharmacy Division. 
    3 A. 33
    –34. Coster acknowledged that “section 1927(k)(2) of the
    Act defines a ‘covered outpatient drug’ based on FDA approval,” but stated that CMS had found
    “no indication that Congress intended that FDA approval status be used for determining whether
    a drug qualifies as a new drug for the purposes of price reporting for the [Medicaid rebate
    program].”
    Id. 33–34. Coster
    noted that the Medicaid Act provides that baseline data should be
    established for each dosage form and strength of the drug, and concluded that “[t]he reasons for
    requiring a new approval for a drug that has new marketing authority do not require different
    Medicaid pricing policies when the dosage form and strength are not changed.”
    Id. 34. Because
    the “new” Somatuline ED products had the same dosage form and strengths as the original
    Somatuline products, and because all of these versions of Somatuline had been approved under
    3
    Dr. Coster’s letter copied the General Counsel of HHS and Ipsen’s General Counsel for North
    America. A.R. 34.
    9
    the same NDA number, Coster reaffirmed CMS’s denial of Ipsen’s request for new base date
    AMPs.
    Id. With regard
    to the relevance of the sNDAs that FDA had approved for Somatuline ED,
    Coster concluded, “[c]onsistent with the statutory language, we consider a sNDA which contains
    the same ‘route number’ with an extension (indicating that it is a supplement to the NDA) to be
    approved under the same NDA, and such products should not have separate baseline data.”
    Coster cited CMS’s previous conclusion to that effect in Manufacturer Release No. 26, which
    stated that “baseline information, such as Market Date and Baseline AMP[,] MUST follow the
    NDA of the product.”
    Id. (emphasis in
    original). Finally, Coster acknowledged the
    enhancements that Ipsen had made to Somatuline, but concluded that “these are not factors
    included in the statutory criteria for determining whether a drug qualifies as a new drug for the
    purposes of price reporting for the [Medicaid rebate program],” and thus the changes did “not
    warrant establishment of new base date AMPs for the three strengths of Somatuline ED.”
    Id. C. Procedural
    History
    Ipsen filed its complaint on December 5, 2016. Compl. Ipsen claims that CMS’s
    determination that Ipsen was not entitled to establish unique base date AMPs for Somatuline ED
    violated the APA’s prohibition on agency action that is “arbitrary, capricious, an abuse of
    discretion or otherwise not in accordance with law.” See 5 U.S.C. § 706(2)(A). Ipsen argues
    that CMS’s determination was “contrary to law and in excess of CMS’s authority” because the
    relevant provision of the Medicaid Act defines “covered outpatient drug” with reference to the
    FDCA, and Somatuline ED constituted a “new drug” under the relevant FDCA provisions.
    Compl. ¶ 75. Ipsen also argues that CMS’s determination was “arbitrary and capricious”
    because CMS had drawn an arbitrary distinction between drug approvals obtained via NDAs and
    10
    those obtained via sNDAs, and because CMS had failed to meet the requirements of reasoned
    decisionmaking.
    Id. ¶ 76,
    77.
    The parties filed cross-motions for summary judgment. See Dkt. 13 (Ipsen); Dkt. 16
    (Secretary). On September 24, 2018, the Court denied Ipsen’s motion for summary judgment
    and granted the Secretary’s cross-motion for summary judgment. Dkt. 23 (Order). The Court
    concluded that CMS’s letter to Ipsen did not constitute “final agency action” subject to judicial
    review under the APA. Dkt. 24 (Mem. Op.) at 13; see 5 U.S.C. § 704 (providing for judicial
    review of “final agency action for which there is no other adequate remedy in a court”).
    On December 3, 2019, the D.C. Circuit reversed. Ipsen Biopharm., Inc. v. Azar, 
    943 F.3d 953
    , 959 (D.C. Cir. 2019). The D.C. Circuit concluded that CMS’s letter had resulted in an
    “increased risk of prosecution and penalties” for Ipsen and therefore did constitute final agency
    action under the Supreme Court’s decision in Bennett v. Spear, 
    520 U.S. 154
    (1997). 
    Ipsen, 943 F.3d at 957
    ; see 
    Bennett, 520 U.S. at 178
    (“final agency action” is “one by which rights or
    obligations have been determined, or from which legal consequences will flow” (internal
    quotation marks and citation omitted)). The D.C. Circuit thus reversed the grant of summary
    judgment to the Secretary and remanded for further proceedings. 
    Ipsen, 943 F.3d at 959
    .
    On remand, the Court afforded the parties the opportunity for supplemental briefing. See
    Minute Order of Feb. 10, 2020. Having received and considered supplemental briefs from both
    parties, the Court will now consider the merits of the parties’ renewed cross-motions for
    summary judgment. See Dkt. 33 (Ipsen); Dkt. 34 (Secretary).
    II.    LEGAL STANDARDS
    Under Rule 56 of the Federal Rules of Civil Procedure, summary judgment is appropriate
    if the moving party “shows that there is no genuine dispute as to any material fact and the
    11
    movant is entitled to judgment as a matter of law.” Fed. R. Civ. P. 56(a); see also Anderson v.
    Liberty Lobby Inc., 
    477 U.S. 242
    , 247–48 (1986). A “material” fact is one that could affect the
    outcome of the lawsuit. See Liberty 
    Lobby, 477 U.S. at 248
    ; Holcomb v. Powell, 
    433 F.3d 889
    ,
    895 (D.C. Cir. 2006). A dispute is “genuine” if a reasonable jury could determine that the
    evidence warrants a verdict for the nonmoving party. See Liberty 
    Lobby, 477 U.S. at 248
    ;
    
    Holcomb, 433 F.3d at 895
    . In reviewing the record, the court “must draw all reasonable
    inferences in favor of the nonmoving party, and it may not make credibility determinations or
    weigh the evidence.” Reeves v. Sanderson Plumbing Prods., 
    530 U.S. 133
    , 150 (2000).
    Under the APA, a reviewing court shall “hold unlawful and set aside” any aspect of a
    final agency action that is “arbitrary [and] capricious, an abuse of discretion, or otherwise not in
    accordance with law.” 5 U.S.C. § 706(2)(A). In an APA challenge to final agency action,
    summary judgment “serves as the mechanism for deciding, as a matter of law, whether the
    agency action is supported by the administrative record and otherwise consistent with the APA
    standard of review.” Sierra Club v. Mainella, 
    459 F. Supp. 2d 76
    , 90 (D.D.C. 2006). In other
    words, “the entire case . . . is a question of law” and the district court “sits as an appellate
    tribunal.” Am. Biosci., Inc. v. Thompson, 
    269 F.3d 1077
    , 1083 (D.C. Cir. 2001) (footnote and
    internal quotation marks omitted).
    Arbitrary and capricious review is “fundamentally deferential—especially with respect to
    matters relating to an agency’s areas of technical expertise.” Fox v. Clinton, 
    684 F.3d 67
    , 75
    (D.C. Cir. 2012) (alteration adopted and internal quotation marks omitted). A court “is not to
    substitute its judgment for that of the agency.” Motor Vehicle Mfrs. Ass’n of U.S. v. State Farm
    Mut. Auto. Ins., 
    463 U.S. 29
    , 43 (1983). Rather, its review is limited to whether the agency
    “relied on factors which Congress has not intended it to consider, entirely failed to consider an
    12
    important aspect of the problem, offered an explanation for its decision that runs counter to the
    evidence before the agency, or is so implausible that it could not be ascribed to a difference in
    view or the product of agency expertise.” Agape Church v. FCC, 
    738 F.3d 397
    , 410 (D.C. Cir.
    2013) (quoting State 
    Farm, 463 U.S. at 43
    ). Courts determine only whether the agency
    “examine[d] the relevant data and articulate[d] a satisfactory explanation for its action including
    a ‘rational connection between the facts found and the choice made.’” State 
    Farm, 463 U.S. at 43
    (quoting Burlington Truck Lines v. United States,

    In conducting this inquiry, a court does “not look at the agency’s decision as would a
    scientist, but as a reviewing court exercising [its] narrowly defined duty of holding agencies to
    certain minimal standards of rationality.” Am. Trucking Ass’ns v. Fed. Motor Carrier Safety

    28 F.3d 1259
    , 1263 (D.C. Cir. 1994) (describing
    the standard as “indulgent”). It is well established that a court “may not supply a reasoned basis
    for the agency’s action that the agency itself has not given.” Bowman Transp., Inc. v. Arkansas-
    Best Freight Sys., Inc., 
    419 U.S. 281

    agency’s decision need not “be a model of analytic precision to survive a challenge.” Dickson v.

    III.   ANALYSIS
    Ipsen makes two arguments against CMS’s decision not to update its base date AMPs for
    Somatuline. First, Ipsen argues that CMS’s interpretation of the statutory and regulatory
    provisions that govern the Medicaid rebate program is contrary to law. Ipsen Mot. for Summ. J.
    at 15–20. Second, Ipsen argues that CMS’s decision not to update its base date AMPs for
    Somatuline was arbitrary and capricious.
    Id. at 20–28.
    The Court will consider each of these
    arguments in turn.
    A.      Contrary to Law
    1.     Chevron Deference
    As a threshold matter, the parties dispute whether CMS's interpretation is entitled to
    Chevron deference. See, e.g., Ipsen Mot. for Summ. J. at 13; CMS Cross-Mot. for Summ. J. at
    15. An agency’s interpretation is entitled to Chevron deference where “Congress [has] delegated
    authority to the agency generally to make rules carrying the force of law” and “the agency
    interpretation claiming deference was promulgated in the exercise of that authority.” United
    States v. Mead Corp., 
    533 U.S. 218
    , 226–27 (2001). “Interpretations such as those in opinion
    letters—like interpretations contained in policy statements, agency manuals, and enforcement
    guidelines, all of which lack the force of law—do not warrant Chevron-style
    deference.” Christensen v. Harris County, 
    529 U.S. 576
    , 587 (2000).
    14
    For three principal reasons, the interpretation of the Medicaid Act articulated in CMS’s
    letter to Ipsen is not entitled to Chevron deference. First, CMS declined to promulgate its
    interpretation pursuant to any formal administrative procedures. While agency interpretations
    announced in informal adjudication may sometimes receive Chevron deference, CMS’s failure to
    employ “those ‘relatively formal administrative procedure[s]’ that ‘tend[] to foster the fairness
    and deliberation that should underlie a pronouncement’ of legal interpretation weighs against the
    application of Chevron deference.” Fogo De Chao (Holdings) Inc. v. U.S. Dep’t of Homeland
    Sec., 
    769 F.3d 1127
    , 1136-37 (D.C. Cir. 2014) (quoting 
    Mead, 533 U.S. at 230
    ); see also FEC v.
    Nat’l Rifle Ass’n, 
    254 F.3d 173
    , 185 (D.C. Cir. 2001) (“[v]irtually every relevant post-
    Christensen decision has declined to give Chevron deference to just this type of informal agency
    action,” namely, a letter issued “pursuant to informal agency procedures”). Second, CMS's letter
    to Ipsen demonstrates on its face that it was not “intended to have general applicability and the
    force of law,” as it was “singularly focused on” one regulated entity and “did not purport to set
    policy for future . . . determinations.” Kaufman v. Nielsen, 
    896 F.3d 475
    , 484 (D.C. Cir. 2018)
    (internal quotation marks omitted). Indeed, CMS did not even release the letter publicly and,
    accordingly, other regulated parties do not even have access to it. Third, CMS’s letter was not
    issued by the head of CMS, but instead by a mid-level agency official. See
    id. at 484–85.
    Taken
    together, these factors strongly suggest that the interpretation of the Medicaid Act articulated in
    CMS’s non-public letter to Ipsen was not “promulgated in the exercise of [CMS’s rulemaking]
    authority,” 
    Mead, 53 U.S. at 227
    , and that Chevron deference therefore does not apply.
    In urging the opposite conclusion, CMS relies heavily on the factors set forth in Barnhart
    v. Walton, 
    535 U.S. 212
    (2002), namely, “the interstitial nature of the legal question, the related
    expertise of the Agency, the importance of the question to administration of the statute, the
    15
    complexity of that administration, and the careful consideration the Agency has given the
    question over a long period of time.”
    Id. at 222.
    To begin with, these are not the exclusive
    factors for determining whether Chevron deference applies to an agency’s interpretation. See
    id. (“In this
    case . . . [these five factors] all indicate that Chevron provides the appropriate legal lens
    through which to view the legality of the Agency interpretation here at issue.” (emphasis
    added)). Even those D.C. Circuit cases that have explicitly applied the Barnhart factors have
    also weighed other considerations that place greater emphasis on the procedural means and
    context of the agency’s interpretation than on the nature of the statutory question itself. See, e.g.,
    
    Kaufman, 896 F.3d at 484
    (applying the Barnhart factors but also considering whether the
    agency interpretation was “clearly intended to have general applicability and the force of law”
    (quoting 
    Fox, 684 F.3d at 78
    )). In any event, not all of the Barnhart factors support the
    application of Chevron deference here because CMS’s two-page letter to Ipsen does not evidence
    “careful consideration . . . over a long period of time.” 
    Barnhart, 535 U.S. at 222
    . To the
    contrary, the letter suggests a one-off explanation of CMS’s understanding of the statute,
    articulated in an informal context that does not indicate that CMS “intended [it] to have general
    applicability and the force of law.” 
    Fox, 684 F.3d at 78
    .
    For the foregoing reasons, CMS’s interpretation does not merit Chevron deference.
    Absent such deference, the Court will “proceed to determine the meaning of [the Medicaid Act]
    the old-fashioned way,” Miller v. Clinton, 
    687 F.3d 1332
    , 1342 (D.C. Cir. 2012), by tackling the
    interpretive question head-on and determining the best reading of the statute for itself.
    2.      The Merits
    On the merits of the statutory question at issue, CMS interprets the relevant provisions to
    allow manufacturers to establish new base date AMPs for a given drug under two circumstances.
    16
    First, the Medicaid Act itself states that the amount of the rebate is calculated “with respect to
    each dosage form and strength of a single source drug or an innovator multiple source drug.” 42
    U.S.C. § 1396r-8(c)(2)(A) (emphasis added). According to the explicit command of the statute,
    if the manufacturer obtains approval for a new dosage form or strength of a drug, it is
    automatically entitled to establish a new base date AMP corresponding to that particular dosage
    form or strength of the drug. Absent those circumstances, CMS argues, the manufacturer may
    establish new base date AMPs only upon obtaining FDA approval of a new NDA pursuant to
    section 505 of the FDCA. That is because, under CMS’s interpretation, only such approval gives
    rise to a new “covered outpatient drug” under the terms of the Medicaid Act. See
    id. § 1396r-
    8(k)(2). CMS’s letters to Ipsen articulate this interpretation of the relevant provisions. See A.R.
    34 (manufacturer is not entitled to establish new base AMPs where the new drug products “have
    the same dosage form and strengths of the original . . . products” and were “approved under the
    same NDA”).
    Several pieces of evidence from the statutory and regulatory framework demonstrate that
    CMS’s interpretation of the relevant provisions is the best one. First and most importantly, the
    interpretation follows straightforwardly from the text of the Medicaid Act. The Act’s rebate
    requirement applies to all “covered outpatient drugs,” see 42 U.S.C. § 1396r-8(a), and the Act
    defines “covered outpatient drug” as “a drug . . . which is approved for safety and effectiveness
    as a prescription drug under section 505” of the FDCA,
    id. § 1396r-
    8(k)(2). Pursuant to section
    505(b) of the FDCA, Ipsen submitted a NDA for Somatuline in October 2006, see A.R. 35, and
    the FDA approved that NDA on August 30, 2007, see
    id. 40. Once
    Ipsen obtained FDA
    approval of the Somatuline NDA, Somatuline became “a drug . . . which is approved for safety
    and effectiveness as a prescription drug under section 505” of the FDCA. 42 U.S.C. § 1396r-
    17
    8(k)(2). Therefore, subsequent changes to Somatuline approved via supplemental filings did not
    establish a new “covered outpatient drug” for purposes of the Medicaid Act because the
    underlying product—Somatuline—already satisfied the condition that it be “approved for safety
    and effectiveness . . . under section 505” of the FDCA.
    Id. Furthermore, the
    additional rebate calculation provision at issue applies to two particular
    types of covered outpatient drugs—“single source drug[s]” and “innovator multiple-source
    drug[s],” see
    id. § 1396r-
    8(c)(2)(A) —and the Medicaid Act’s definitions of those terms further
    support CMS’s interpretation. The Act defines “single source drug” as “a covered outpatient
    drug . . . which is produced or distributed under a new drug application approved by [FDA],”
    id. § 1396r-
    8(k)(7)(iv), 
    and an “innovator multiple source drug” as “a multiple source drug that is
    marketed under a new drug application approved by [FDA],”
    id. § 1396r-
    8(k)(7)(ii). 
    The
    specific references in both definitions to a “new drug application” support CMS’s conclusion
    that Somatuline, the subject of the original NDA that FDA approved in 2007—and not its
    multiple, subsequent, merely improved iterations—is the relevant unit for purposes of Ipsen’s
    rebate calculation. The Medicaid Act’s implementing regulations further buttress that
    conclusion. The regulatory definitions for both of the above-referenced categories of drugs
    specifically reference “an original new drug application (NDA) approved by FDA,” 42 C.F.R.
    § 447.502 (emphasis added), and the definition of a “single-source drug” is even linked to “an
    approved NDA number issued by FDA,”
    id. These definitions
    further undermine the notion that
    subsequent changes to an original NDA—such as those approved through the sNDA process—
    could establish a new drug for purposes of calculating Ipsen’s additional-rebate liability.
    Finally, the contrast between NDAs and sNDAs makes clear that only the former (absent
    a change to the dosage form or strength of the drug) can give rise to a new “covered outpatient
    18
    drug” for purposes of Medicaid rebate calculations. Just as the name suggests, sNDAs are
    supplements to preexisting drug applications that FDA has already approved. That is clearly
    reflected in the FDCA’s implementing regulations defining and authorizing sNDAs, which
    establish a separate approval process that applies whenever a manufacturer wishes to make
    “[s]upplements and other changes to an approved NDA.” 21 C.F.R. § 314.70 (emphasis added).
    The entire sNDA process therefore presumes that there is an existing NDA to supplement. And
    the changes that require a manufacturer to submit a sNDA are those that might adversely affect
    various characteristics “of the drug product as these factors may relate to the safety or
    effectiveness of the drug product.”
    Id. § 314.70(b)
    (emphasis added). The sNDA requirement,
    therefore, also assumes that there is an existing drug that might be adversely affected by the
    proposed changes. In light of these provisions, while Ipsen might be correct to argue that sNDAs
    are “approved for safety and effectiveness . . . under section 505” of the FDCA, 42 U.S.C.
    § 1396r-8(k)(2), a sNDA does not establish a unique “drug . . . approved for safety and
    effectiveness . . . under section 505,”
    id. (emphasis added),
    because it merely adds to a
    preexisting drug. For the above reasons, CMS’s interpretation of the statutory framework is the
    best one: absent a change to the drug’s dosage form or strength, a new drug for Medicaid rebate
    purposes is defined by the FDA’s approval of a new drug application under section 505 of the
    FDCA. 4
    4
    While the Court adopts CMS’s interpretation without affording it the benefit of deference, the
    Court notes for the record the consistency of this interpretation with CMS’s practice of treating
    NDA approval as determinative of base date information for Medicaid rebate calculation
    purposes. See, e.g., A.R. 91 (“Baseline information, such as Market Date and Baseline AMP
    MUST follow the NDA of the product.” (emphasis in original)). Moreover, while no other court
    has squarely addressed this issue before now, this Court has previously speculated that the
    unchallenged nature of CMS’s approach in this general arena “might be because the statute is
    clear.” Mallinkcrodt ARD LLC v. Verma, et al., 19-cv-1471 (TFH), Dkt. 46 (Mem. Op.) at 22.
    19
    Ipsen poses many objections to CMS’s interpretation, but all are ultimately unavailing.
    First, Ipsen argues that “the [Medicaid] Act makes clear that Congress intended that CMS look
    to the existing FDCA regime” when administering the Medicaid rebate program. Ipsen Mot. for
    Summ. J. at 15. It is true that the Act frequently directs CMS to the FDCA or FDA regulations
    in administering Medicaid, but the Act does so only in specific circumstances delineated in the
    statutory text. See, e.g., 42 U.S.C. § 1396r-8(a)(3)(A)(ii) (requiring payment for a drug only if
    FDA has given the drug a particular rating);
    id. § 1396r-
    8(e)(4) (setting a reimbursement limit
    for certain drugs that FDA has rated “therapeutically and pharmaceutically equivalent” to other
    drugs). The Medicaid Act does not adopt the entire FDCA wholesale, and this case deals with a
    particular provision of the Medicaid Act that refers to “a drug which is approved for safety and
    effectiveness as a prescription drug under section 505” of the FDCA. 42 U.S.C. § 1396r-8(k)(2).
    For the reasons described above, CMS correctly interpreted that provision to refer to a drug
    approved under section 505 pursuant to an original NDA, and not to subsequent, altered versions
    of a preexisting drug where changes from the original version were approved by supplements to
    the original NDA.
    Second, Ipsen points to the FDCA’s “Definitions” section, which defines the term “new
    drug,” in relevant part, to mean “[a]ny drug . . . the composition of which is such that such drug
    is not generally recognized, among experts qualified by scientific training and experience to
    evaluate the safety and effectiveness of drugs, as safe and effective for use under the conditions
    prescribed, recommended, or suggested in the labeling thereof.” 21 U.S.C. § 321(p). This
    provision favors Ipsen because the language of the definition seemingly links the standard for a
    “new drug” to the proven safety and effectiveness of the conditions of use listed on the product’s
    label, and some of the changes for which Ipsen obtained approval by sNDA—most notably,
    20
    Somatuline’s new indication for the treatment of GEP-NETs—did require changes to those
    conditions of use. Nevertheless, this definition does not overcome CMS’s interpretation of the
    overall statutory and regulatory scheme for several reasons.
    First and most importantly, the Medicaid Act—the ultimate authority on the question of
    Ipsen’s entitlement to new base date AMPs for Somatuline—does not incorporate this definition
    from the FDCA. Instead, the Medicaid Act defines “covered outpatient drug” as “a drug . . .
    which is approved for safety and effectiveness as a prescription drug under section 505” of the
    FDCA. 42 U.S.C. § 1396r-8(k)(2) (emphasis added). For the reasons described above, that
    means that a distinct “drug” for Medicaid rebate purposes is defined by FDA’s approval of a
    distinct NDA pursuant to section 505.
    Moreover, Ipsen’s reliance on the definition of “new drug” in the FDCA proves too
    much. An enormous number of potential changes to a drug product would require a
    manufacturer to obtain FDA approval for changes to the conditions of use listed on a drug
    product’s label. Some such changes—for example, changes to the recommendations for patient
    monitoring, 21 C.F.R. § 201.57(a)(10), or the recommended use by specific populations,
    id. § 201.57(a)(13)—would
    surely not automatically entitle a manufacturer to declare a “new drug”
    for Medicaid rebate purposes. But taking the FDCA’s definition of “new drug” as the ultimate
    basis for a manufacturer’s entitlement to new base date AMPs would require precisely that
    result.
    Furthermore, relying on the FDCA’s definition of a “new drug” in determining a
    manufacturer’s eligibility for new base date AMPs would render at least one aspect of the
    Medicaid Act mere surplusage. Recall that the Act specifically directs manufacturers to establish
    new base date AMPs for each distinct “dosage form” and “strength” of a drug. See 42 U.S.C.
    21
    § 1396r-8(c)(2). But changes to “dosage form” and “strength” would plainly establish a “new
    drug” under the FDCA’s definition, and therefore, under Ipsen’s argument, would already
    establish new base date AMPs absent that provision of the Medicaid Act. If Ipsen were correct
    that the Medicaid Act incorporates the FDCA’s definition of “new drug” wholesale, then the
    Medicaid Act’s specific references to “dosage form” and “strength” would be unnecessary. “It is
    . . . a cardinal principle of statutory construction that we must give effect, if possible, to every
    clause and word of a statute.” Williams v. Taylor, 
    529 U.S. 362
    , 404 (2000) (internal quotation
    marks omitted). The references to “dosage form” and “strength” in the Medicaid Act’s rebate-
    calculation provisions therefore suggest that Congress did not intend CMS to rely on the FDCA’s
    definition of “new drug” when calculating manufacturers’ rebate obligations under those
    provisions. In short, taking into account the fact that the Medicaid Act does not incorporate the
    FDCA’s definition of “new drug,” as well as the inconsistency of that definition with other
    features of the statutory and regulatory scheme at issue here, CMS interpreted the relevant
    provisions correctly notwithstanding that definition.
    Third, Ipsen objects that CMS’s position—that approval of a NDA, but not a sNDA,
    entitles the manufacturer to set new base date AMPs—is “arbitrary” and “untethered” to any
    statutory provision. See, e.g., Mot. for Summ. J. at 20 (“It is an utterly arbitrary distinction given
    that a manufacturer is legally permitted to proceed via either avenue.”). For the reasons stated
    above, CMS’s position is not untethered to statute, but is instead required by section 1396r-8 of
    the Medicaid Act and section 505 of the FDCA. To the extent Ipsen finds the significance of a
    FDA-approved NDA “arbitrary,” its quarrel is with Congress, not CMS. Moreover, Ipsen is
    wrong to the extent that it suggests that CMS’s interpretation would prevent manufacturers from
    resetting their base date information for substantial changes approved via sNDA while permitting
    22
    them to do so for trivial changes approved via NDA. See, e.g., Dkt 31 (Ipsen Suppl. Reply.) at 4.
    Under CMS’s interpretation, a new NDA (absent changes to the drug’s dosage form or strength)
    is necessary, but not always sufficient, to establish new base date information for Medicaid
    rebate purposes. Minor changes approved via NDA—to the extent that FDA regulations even
    permit such approvals—might well fail to establish a new “covered outpatient drug” under
    certain circumstances. Cf. Dkt. 32 (CMS Sur-Reply) at 3 n.1 (“[T]here is no evidence in the
    record of how the FDA would treat an application to make changes to an existing drug product
    where the manufacturer submits a new NDA but could permissibly have submitted a
    supplemental NDA.”).
    Fourth, Ipsen argues that it should be entitled to reset its base date AMPs for Somatuline
    because the research it conducted to establish Somatuline’s new indication for GEP-NETs
    entitled it to three years of “new drug product exclusivity” under the FDCA. See, e.g., Mot. for
    Summ. J. at 16. As a result, for the next three years, FDA will not approve another drug
    manufacturer’s application based on the same clinical trials that Ipsen conducted to support
    Somatuline’s new indication. See 21 U.S.C. 355(c)(3)(E)(iii). This argument does not
    undermine CMS’s interpretation. To begin with, the phrase “new drug product exclusivity” is a
    term used by Ipsen, not by the actual statutory provision that entitles Ipsen to that benefit. See
    id. Moreover, the
    fact that Congress conferred this particular benefit upon drug manufacturers in
    order to incentivize the substantial investments necessary to approve a drug for a new indication
    does not mean that Congress also intended to incentivize such investments by reducing
    manufacturers’ Medicaid rebate obligations to the states. To the contrary, if anything, the
    inclusion of an express provision granting “new drug product exclusivity” to manufacturers in
    23
    Ipsen’s position suggests that Congress did not impliedly provide additional incentives elsewhere
    in the statutory scheme.
    Fifth, Ipsen points to recent amendments to the Medicaid Act that alter the rebate
    calculation for “a drug that is a line extension of a single source drug or an innovator multiple
    source drug that is an oral solid dosage form.” 42 U.S.C. § 1396r-8(c)(2)(C). Under these
    amendments, in effect, the manufacturer’s rebate liability for the new “line extension” reverts to
    the highest additional rebate of the original drug product. See
    id. Congress added
    these
    provisions to the Act in order to prevent drug manufacturers from “avoid[ing] incurring
    additional rebate obligations by making slight alterations to existing products, sometimes called
    line extensions.” S. Rep. No. 111-89 (2009). According to Ipsen, these amendments reveal
    Congress’s background understanding that under the Medicaid Act, “modifications to existing
    drugs . . . are generally considered new products for purposes of reporting AMPs to CMS.”
    Id. Because Congress
    chose to alter this background principle explicitly for “line extension[s]” of
    drugs in “oral solid dosage form,” 42 U.S.C. § 1396r-8(c)(2)(C), Ipsen contends, that principle
    remains in place for injectable drugs like Somatuline. See Mot. for Summ. J. at 19–20.
    But the “line-extension amendments” are not inconsistent with CMS’s interpretation. For
    one thing, the amendments prevent manufacturers from making minor changes to existing drugs
    through the NDA (rather than sNDA) process, and then claiming entitlement to new base date
    AMPs on that basis. As discussed above, that remains at least a potential loophole under CMS’s
    interpretation of the statutory scheme, one that the line-extension amendments have definitively
    closed for “oral solid dosage form” drugs. For another, the amendments appear to be aimed at
    “extended release formulations” of preexisting drugs, see 42 U.S.C. § 1396r-8(c)(2)(C) (defining
    “line extension” as “a new formulation of the drug, such as an extended release formulation”),
    24
    which typically involve changes to the dosage form or strength of a drug. Given the clear terms
    of the Medicaid Act requiring new base date information for a new dosage form or strength of a
    drug, see
    id. § 1396r-
    8(c)(2)(A), those changes would also entitle a manufacturer to new base
    date AMPs under CMS’s interpretation. In these circumstances, too, the line-extension
    amendments prevent that outcome for new versions of “oral solid dosage form” drugs. Thus, the
    amendments do not reveal a baseline statutory principle that contradicts CMS’s theory.
    More generally, the Supreme Court has “frequently cautioned that it is at best treacherous
    to find in congressional silence alone the adoption of a controlling rule of law.” United States v.
    Wells, 
    519 U.S. 482
    , 496 (1997) (quoting NLRB v. Plasterers’ Local Union No. 79, 
    404 U.S. 116
    , 129–30 (1971) (internal quotation marks omitted); see also Burns v. United States, 
    501 U.S. 129
    , 136 (1991) (“[A]n inference drawn from congressional silence certainly cannot be credited
    when it is contrary to all other textual and contextual evidence of congressional intent.”). Given
    the broader statutory context described in detail above, Ipsen relies too heavily on a contestable
    inference from a statutory provision that ultimately does not even address the type of drug
    (injectable) at issue in this dispute.
    Finally, Ipsen points to two of CMS’s own regulatory releases. As Ipsen interprets these
    items, both demonstrate that a new national drug code (NDC) can establish a new “drug” for
    Medicaid rebate purposes or otherwise entitle a manufacturer to establish new base date
    information even absent FDA’s approval of a new NDA. 5 First, Ipsen points to a CMS
    regulation that defines “bundled sale” as “any arrangement regardless of physical packaging
    5
    It is worth noting, at the outset, that this theory is expressly contradicted by the great weight of
    CMS’s regulatory output, which repeatedly establishes that “[b]aseline information, such as
    Market Date and Baseline AMP MUST follow the NDA of the product” and “does NOT follow
    the NDC of the product.” A.R. 91–92 (CMS Release No. 26); see also
    id. 100 (Release
    No. 38)
    (same);
    id. 110 (Release
    No. 48) (same).
    25
    under which the rebate, discount, or other price concession is conditioned upon the purchase of
    the same drug [or] drugs of different types (that is, at the nine-digit national drug code (NDC)
    level).” 42 C.F.R. § 447.502. Ipsen argues that if “drugs of different types” are defined by new
    NDCs, rather than FDA-approved NDAs, Ipsen should be allowed to reset its base date
    information without obtaining the latter form of approval. But Ipsen relies much too heavily on
    the phrase “drugs of different types,” which is not defined in the regulation and does not
    preclude the possibility that several “drugs of different types,” in the context of a “bundled sale,”
    may nonetheless constitute a single “covered outpatient drug” for Medicaid rebate purposes. See
    42 U.S.C. § 1396r-8(k)(2).
    Ipsen also relies on CMS Release No. 48, which states that when a company “buys a
    product, changes something . . . and applies for an ANDA, the NDC that reflects the product
    under the new ANDA has history start over for itself.” A.R. 110. An aNDA—a required form
    of approval for generic drugs that is not at issue in this litigation—is approved under section
    505(j) of the FDCA, and the Medicaid Act explicitly provides that approval under that section
    gives rise to a new “covered outpatient drug.” 42 U.S.C. § 1396r-8(k)(2). Therefore, Release
    No. 48 is consistent with the express terms of the Medicaid Act and does not contradict CMS’s
    interpretation. In short, these two regulatory items provide little, if any, support for Ipsen’s
    challenge to CMS’s interpretation.
    In sum, CMS has offered the best interpretation of a complex statutory and regulatory
    scheme: absent a change to the dosage form or strength of a drug,
    id. § 1396r-
    8(c)(2)(A), or
    FDA’s approval of a new NDA (or aNDA) under section 505 of the FDCA, see
    id. § 1396r-
    8(k)(2), a given drug product remains the same “covered outpatient drug” under the Medicaid
    Act and the drug manufacturer is not entitled to reset base date AMPs for the product.
    26
    Accordingly, the Court will reject Ipsen’s argument that CMS’s interpretation of the relevant
    provisions is contrary to law.
    B.      Arbitrary and Capricious
    Ipsen also argues that CMS’s ultimate decision—that Ipsen would not be allowed to reset
    its base date AMPs for Somatuline—was arbitrary and capricious. See 5 U.S.C. § 706(2)(A).
    Arbitrary-and-capricious review asks whether the agency “relied on factors which Congress has
    not intended it to consider, entirely failed to consider an important aspect of the problem, offered
    an explanation for its decision that runs counter to the evidence before the agency, or is so
    implausible that it could not be ascribed to a difference in view or the product of agency
    expertise.” Agape 
    Church, 738 F.3d at 410
    (quoting State 
    Farm, 463 U.S. at 43
    ). The agency’s
    decision need not “be a model of analytic precision to survive a challenge,” 
    Dickson, 68 F.3d at 1404
    , and “[e]ven an agency ‘decision of less than ideal clarity’ should be upheld ‘if the
    agency’s path may be reasonably discerned,’” Anacostia Riverkeeper, 
    Inc., 798 F. Supp. 2d at 222
    (quoting State 
    Farm, 463 U.S. at 43
    ).
    Ipsen argues, first and most strenuously, that CMS acted arbitrarily and capriciously
    because it failed to adequately justify its decision. Ipsen Mot. for Summ. J. at 21–24. In
    particular, Ipsen argues, CMS relied exclusively on the fact that Somatuline ED shared the same
    dosage form and strengths as the original Somatuline, while failing to consider the more nuanced
    statutory question of whether Somatuline nonetheless constituted a new “covered outpatient
    drug.” But in Coster’s August 3, 2016 letter, CMS acknowledged and responded to Ipsen’s
    statutory argument. In that letter, CMS reasoned that “[c]onsistent with the statutory language,
    we consider a sNDA which contains the same ‘route number’ with an extension (indicating that
    it is a supplement to the NDA) to be approved under the same NDA, and such products should
    27
    not have separate baseline data.” A.R. 34. The agency further explained that “[t]he reasons for
    requiring a new approval for a drug that has new marketing authority [i.e., a sNDA] do not
    require different Medicaid pricing policies when the dosage form and strength are not changed.”
    Id. 34. These
    statements surpass the lenient arbitrary-and-capricious threshold for agency
    decisionmaking. While the agency certainly could have engaged in a more robust statutory
    analysis, “[e]ven an agency ‘decision of less than ideal clarity’ should be upheld ‘if the agency’s
    path may be reasonably discerned,’” Anacostia 
    Riverkeeper, 798 F. Supp. 2d at 222
    . CMS’s
    path can be reasonably discerned here, as the agency considered the statutory text and concluded
    that the approval of a sNDA for a preexisting drug would not suffice to establish a new drug for
    Medicaid rebate purposes absent a change to the drug’s dosage form or strength. 6
    Ipsen also argues that CMS failed to provide Ipsen with fair notice of its interpretation.
    Ipsen Mot. for Summ. J. at 25–27. At the outset, this argument is difficult to accept given that
    Ipsen’s initial letter to CMS requesting permission to establish new base date AMPs articulated
    the agency’s interpretation accurately and precisely. See A.R. 2 n.5 (“CMS has often stated that
    the baseline AMP ‘follows the NDA, not the NDC.’ The releases are very specific about
    following the NDA, and a supplemental NDA is distinct from an NDA.” (citation omitted)
    6
    CMS’s reliance on the statutory text, as demonstrated by the above quotations, also answers
    Ipsen’s criticism that CMS unduly relied on the purportedly inapposite CMS Release No. 26,
    which states that “[b]aseline information, such as Market Date and Baseline AMP MUST follow
    the NDA of the product” and “does NOT follow the NDC of the product.” A.R. 91–92
    (emphasis in original). CMS’s decision to deny Ipsen’s request ultimately derived from CMS’s
    interpretation of the overall statutory framework governing Medicaid rebate calculations. While
    CMS cited Release No. 26 in support of that decision, its decision did not hinge on that release.
    In any event, Release No. 26 is not inapposite to the statutory question at issue, as Ipsen
    contends. See Ipsen Mot. for Summ. J. at 21–23. While Release No. 26 addresses a technically
    distinct factual situation—where one company purchases a FDA-approved drug from another
    company—it articulates a general principle that base date information “follows the NDA of the
    product,” A.R. 91, and CMS reasonably viewed that principle as extending more broadly to
    encompass the circumstances presented by Ipsen’s changes to Somatuline.
    28
    (emphasis in original)). The administrative record therefore belies any suggestion that Ipsen was
    caught unaware when it discovered CMS’s view.
    In any event, CMS provided notice of its interpretation in multiple public releases prior to
    its decision on Ipsen’s particular case. See A.R. 91 (Release No. 26) (“Baseline information,
    such as Market Date and Baseline AMP MUST follow the NDA of the product”);
    id. 100 (Release
    No. 38) (“Baseline information . . . MUST follow the NDA of the product”);
    id. 105 (Release
    No. 43) (similar) (“[P]rovide information such as . . . Market Date (of the NDA) . . .”);
    id. 110 (Release
    No. 48) (“History follows the NDA, NOT the NDC of the product”). While
    these releases addressed different factual circumstances than those at issue in this dispute, they
    nevertheless consistently articulated the general principle that base date information would
    “follow the NDA” of the drug—and Ipsen recognized the potential applicability of that principle
    in its initial letter to CMS, see
    id. 2 n.5.
    This degree of notice adequately discharged CMS’s
    obligations under the lenient standards of the APA.
    Next, Ipsen points to other instances in which manufacturers sought to obtain CMS’s
    approval to update the base date AMPs for their drugs. In some of those cases, CMS consulted
    with FDA about whether the modifications at issue sufficed to establish a new drug. See, e.g.,
    A.R. 123–25. Ipsen argues that CMS’s failure to consult FDA in the same manner regarding the
    changes to Somatuline rendered CMS’s decision arbitrary and capricious. But Ipsen’s argument
    concerns CMS’s internal deliberative processes, and CMS is not obligated to employ the same
    deliberative processes in each case, so long as each decision is supported by the information
    before it. See Fox, 
    684 F.3d 67
    , 74–75. In pressing its argument to the contrary, Ipsen relies
    heavily on Wilhelmus v. Geren, 
    796 F. Supp. 2d 157
    (D.D.C. 2011). But Wilhelmus concerned
    an agency’s failure to distinguish its own on-point precedent, which required remand because it
    29
    violated the agency’s obligation to reach similar results for similarly situated parties.
    Id. at 162–
    63. Wilhelmus says nothing about an agency’s obligation to employ the same deliberative
    processes in every case. And Ipsen has not alleged that it is similarly situated to any
    manufacturers for whom CMS reached a different result.
    Finally, Ipsen repackages two of its arguments against CMS’s legal interpretation as
    arbitrary-and-capricious claims. First, Ipsen, argues that CMS acted arbitrarily and capriciously
    because it failed to consider its own contrary guidance purportedly contained in CMS Release
    No. 48 and in 42 C.F.R. § 447.502, the regulation defining the term “bundled sale.” Ipsen Mot.
    for Summ. J. at 22–23. For the reasons described above, these provisions have little to no
    significance to the interpretive question before the agency. But in any event, Ipsen waived any
    argument based on these two provisions by failing to raise them prior to its opening brief. See
    Coburn v. McHugh, 
    679 F.3d 924
    , 929 (D.C. Cir. 2009) (quoting United States v. Tucker Truck
    Lines, Inc., 
    344 U.S. 33
    , 37 (1952)) (referencing the “hard and fast rule of administrative law,
    rooted in simple fairness, that issues not raised before an agency are waived and will not be
    considered by a court on review”).
    Second, Ipsen argues that CMS’s decision relied on a “substantively arbitrary” distinction
    between NDAs and sNDAs, Ipsen Mot. for Summ. J. at 25, and that therefore CMS has failed to
    articulate a “rational connection between the facts found and the choice made.” State 
    Farm, 463 U.S. at 43
    . This argument fails for the reasons stated above in response to Ipsen’s legal
    “arbitrariness” argument. In short, CMS’s decision has a sound basis in the applicable statutory
    scheme: sNDAs reflect changes to preexisting “covered outpatient drugs” that have already been
    “approved for safety and effectiveness as a prescription drug under section 505” of the FDCA.
    30
    42 U.S.C. § 1396r-8(k)(2)(A)(i). Any arbitrariness that Ipsen sees in the resulting significance of
    NDAs (as opposed to sNDAs) is therefore attributable to Congress, not CMS.
    CONCLUSION
    For the foregoing reasons, the Court will grant CMS’s Renewed Motion for Summary
    Judgment and deny Ipsen’s Renewed Cross-Motion for Summary Judgment. A separate order
    consistent with this decision accompanies this memorandum opinion.
