    December 23, 2016
    KAYATTA, Circuit Judge.           This qui tam action makes its
    second appearance before us.          Last year, we held that the district
    court should have evaluated Jeffrey D'Agostino's request for leave
    to file his fourth amended complaint under the standard set forth
    in Federal Rule of Civil Procedure 15(a).                United States ex rel.
    D'Agostino v. ev3, Inc. (D'Agostino I), 
    802 F.3d 188
    , 193–96 (1st
    Cir. 2015).      On remand, the district court found that D'Agostino's
    desired amendment failed under that standard because, even as
    proposed to be amended, the complaint did not allege claims upon
    which    the    court    could   grant    relief.      United   States    ex   rel.
    D'Agostino v. ev3, Inc., 
    153 F. Supp. 3d 519
    , 538 (D. Mass. 2015).
    For the following reasons, we agree.
    I.   Background
    A.      Factual Allegations
    Defendant    ev3,     Inc.   ("ev3")     discovers,      develops,
    manufactures,      and    markets     medical     devices.      Defendant      Micro
    Therapeutics, Inc. ("MTI"), ev3's subsidiary since 2006, likewise
    manufactures and markets medical devices.                D'Agostino's original
    and proposed complaints against these companies focus on two
    devices, the Onyx Liquid Embolic System ("Onyx") and the Axium
    Detachable Coil System ("Axium").                We recite the relevant facts
    concerning each device as they are alleged by D'Agostino in his
    proposed complaint, assuming them to be true unless they are merely
    conclusory.      See Ashcroft v. Iqbal, 
    556 U.S. 662
    , 678 (2009).
    - 3 -
    1.   Onyx
    Onyx is an artificial liquid material developed by MTI
    to treat malformed blood vessels in the brain.            In plain terms, it
    is injected into blood vessels near the brain, and then forms a
    mass blocking the flow of blood to facilitate subsequent surgery.
    In the early 2000s, MTI licensed the Onyx molecule to a company
    named Enteric.       Enteric used the molecule to develop another
    medical device, Enteryx, which went to market first, after gaining
    Food and Drug Administration ("FDA") approval in April 2003 for
    the treatment of gastroesophageal reflux disease.                  A series of
    adverse events involving Enteryx followed, prompting a patient
    safety alert in October 2004, and culminating in a complete recall
    of the device in September 2005.
    It was during this timeframe--between Enteryx's approval
    and   recall--that    MTI   sought    approval    for    Onyx.          The   FDA's
    regulations   require   a   premarket    approval       ("PMA")    process     for
    medical devices like Onyx.     See 21 C.F.R. § 814.1(c).            During that
    process, the device manufacturer supplies the FDA with extensive
    information     regarding     the     device--including           its     design,
    manufacturing, packing, labeling, and testing--to satisfy the
    agency that the device is safe and effective.               
    Id. § 814.20.
            A
    "sufficiently     complete"   application        proceeds    to    substantive
    review.    
    Id. § 814.42(a).
             That review is performed by FDA
    personnel and, at the FDA's election as in this instance, by an
    - 4 -
    advisory panel of outside experts.            
    Id. § 814.44(a).
           The panel
    holds   a   public   meeting    to   review    the   PMA    before    making      a
    recommendation to the FDA.            
    Id. § 814.44(b).
             The FDA then
    considers the PMA application, together with any advisory panel
    report and recommendation, before issuing a decision on approval.
    
    Id. § 814.44(c).
    MTI's PMA application identified a narrow indication for
    Onyx:   "use in the treatment of brain arteriovenous malformations
    ('BAVM's'), when embolization is indicated to minimize blood loss
    to reduce the BAVM size prior to surgery." While seeking approval,
    MTI emphasized the narrow scope of the indication as well as the
    rigorous nature of the training program required for physicians
    using Onyx.       According to the testimony of MTI's Vice President
    before the FDA advisory panel, that training program would include
    an instructional session, a hands-on workshop, a case review, and
    observations.      According to another MTI witness, any physician who
    completed    this    training   would   receive      the   assistance      of    an
    experienced proctor the first time he or she used Onyx.                         The
    advisory panel members placed great weight on these training
    requirements, describing them as "critically important" and "a
    very big component of getting [Onyx] into safe use."
    The    panel   ultimately   recommended        approval   of   Onyx.
    However, several of its members explained that it was a "cautious
    approval," and others warned that they would advise the FDA to
    - 5 -
    rescind       approval    if    MTI     disregarded          their     suggestions         for
    carefully monitoring Onyx cases.
    The FDA adopted the panel's recommendation, granting
    approval to Onyx in July 2005.                   The Onyx label authorized by the
    FDA     restricted       the     device's            use      to     "physicians           with
    neurointerventional        training         and     a   thorough      knowledge       of   the
    pathology      to   be   treated,      angiographic          techniques,        and    super-
    selective       embolization."              It     stated,     "Contact     your        Micro
    Therapeutics Inc. sales representative for information on training
    courses."
    Enter D'Agostino, a sales representative who worked at
    ev3 from January 2005 until his termination in January 2010. After
    ev3 acquired MTI in 2006, D'Agostino became familiar with the
    manner in which the defendants promoted and sold Onyx.                                He says
    that he observed physician trainings that lasted as little as four
    hours and proctored surgeries that involved off-label procedures.
    He     also    alleges    that        the        defendants        instituted     a     "Site
    Certification Process" whereby they certified and sold Onyx to any
    site where a single neurosurgeon who had completed their training
    enjoyed privileges.        As a result, he says that Onyx fell into the
    hands of physicians at those sites with inadequate training or no
    training at all.          Additionally, the defendants encouraged off-
    label marketing by setting sales quotas for their representatives
    that    anticipated      such    sales,          educating    their     sales    force      on
    - 6 -
    "peripheral applications," and providing off-label training to
    physicians during all-expenses-paid retreats.                    All in all, it
    became     clear,      alleges    D'Agostino,   that     the   defendants   never
    intended to honor the commitments that MTI had made to the FDA.
    2.       Axium
    Because clinical trials involving Onyx in the treatment
    of aneurysms evinced numerous complications, the defendants in
    2007 launched a new medical device, Axium.1                    Put simply, Axium
    provides another means of generating an embolism to facilitate the
    surgical treatment of anomalies in blood vessels in the brain.
    Surgeons use the device to place a small, detachable coil at a
    desired spot to generate a blockage of blood flow to an abnormality
    such as an aneurysm.             Following the initial launch in 2007, the
    defendants redesigned the device several times in response to
    reports that it malfunctioned during procedures.                   They did not,
    however,       recall   earlier     generations    or    relabel   any   devices.
    Problems persisted, notwithstanding frequent modifications.                    On
    top       of    these     design     challenges,        irregularities      during
    manufacturing resulted in defective lots of the devices that the
    defendants nonetheless sold.           D'Agostino, who also promoted Axium,
    attended a February 2009 meeting where top brass admonished the
    1The proposed complaint does not allege that Axium was not
    FDA-approved.
    - 7 -
    sales force to keep quiet about defects in hopes of dodging FDA
    scrutiny.
    3.     Qui Tam Action
    Approximately one year later, the defendants terminated
    D'Agostino's employment.          In October 2010, he brought this qui tam
    action as a "relator" on behalf of the United States under the
    False Claims Act ("FCA"), 31 U.S.C. §§ 3729–3733, and on behalf of
    numerous    states   under    similar      state   statutes.       The   relevant
    provisions of the FCA are those imposing liability on anyone who
    "knowingly    presents,      or   causes    to   be   presented,    a    false   or
    fraudulent claim for payment or approval," 
    id. § 3729(a)(1)(A),
    or
    "knowingly makes, uses, or causes to be made or used, a false
    record or statement material to a false or fraudulent claim," 
    id. § 3729(a)(1)(B).
        D'Agostino's proposed complaint accuses ev3 and
    MTI of violating those provisions in selling Onyx and Axium to
    hospitals that seek reimbursement from the federal government
    through, for example, the Center for Medicare and Medicaid Services
    ("CMS").
    B.   Procedural History
    Our opinion in D'Agostino I provides a full recitation
    of the suit's early procedural 
    history, 802 F.3d at 190
    –91, which
    we repeat only briefly here.                D'Agostino filed his original
    complaint under seal in October 2010 and amended the complaint as
    a matter of course in February 2011.                  Through two subsequent
    - 8 -
    amendments, both with permission of the court, D'Agostino added
    several defendants2 and retooled his claims.          In October 2013, the
    United States declined to intervene, and the court lifted the seal
    and authorized service.         The parties then submitted a joint
    briefing schedule to the court for the defendants' motion to
    dismiss. The court endorsed the schedule and the defendants timely
    filed their motion.
    A few days before his opposition was due, D'Agostino
    filed a fourth amended complaint (i.e., his fifth version of the
    complaint).    The defendants immediately moved to strike, insisting
    that D'Agostino had used up his right to amend as a matter of
    course back in February 2011.          The court agreed but construed
    D'Agostino's filing as a request for leave to amend.            It applied
    to that request the "good cause" standard from Rule 16(b) of the
    Federal Rules of Civil Procedure and struck the amended complaint
    for want of good cause.       His fourth amended complaint rejected,
    D'Agostino    opposed   the   motion   to   dismiss    his   third   amended
    complaint.     The district court sided with the defendants, ruling
    that certain claims were subject to the FCA's public disclosure
    2 The defendants named in the fourth amended complaint are
    ev3, MTI, and two individuals: John H. Hardin II, a Vice President
    of Sales at ev3 who oversaw Onyx and Axium, and Brett Wall, a
    Director at MTI who joined ev3 to serve as a Vice President of
    Marketing.    During the pendency of this appeal, D'Agostino
    voluntarily dismissed with prejudice his appeal as to those
    individual defendants.

    bar, 31 U.S.C. § 3730(e)(4), and that the remaining claims failed
    to satisfy the pleading requirements of Rules 9(b) and 12(b)(6).
    See United States ex rel. D'Agostino v. ev3, Inc., No. 10-CV-
    11822, 
    2014 WL 4926369
    , at *5–9 (D. Mass. Sept. 30, 2014).
    In the appeal that followed, we held that the district
    court   erred    by    applying    Rule   16(b)'s   standard    rather   than
    Rule 15(a)'s more lenient standard.             D'Agostino 
    I, 802 F.3d at 194
    .    We therefore remanded the case to the district court to
    evaluate under Rule 15(a) D'Agostino's request to file a fourth
    amended complaint.      
    Id. at 195–96.
          After briefing and argument on
    the proposed amendment, the district court once again denied
    D'Agostino's request to file a fourth amended complaint.                   See
    
    D'Agostino, 153 F. Supp. 3d at 525
    .          As before, the district court
    determined that certain claims were subject to the FCA's public
    disclosure    bar.      
    Id. at 530–32.
         Others,   it   found,   lacked
    particularity per Rule 9(b), 
    id. at 533–38,
    or otherwise failed to
    state a claim upon which relief can be granted per Rule 12(b)(6),
    
    id. at 538–39.
          It therefore deemed the motion to amend futile.
    In addition to finding the proposed amendment futile,
    the district court expressed the "tentative view that permitting
    a further amendment would substantially prejudice the individual
    defendants," 
    id. at 539,
    but decided it was "not necessary for the
    court to definitively resolve the issue," 
    id. at 540.
                 The court
    finally noted that it was "inclined to agree" with undue delay
    - 10 -
    arguments advanced by the defendants, which faulted D'Agostino for
    labeling as "new evidence" information that he could have obtained
    through    reasonable         diligence    before     filing   the   third   amended
    complaint.       
    Id. This appeal
    followed.
    II.     Discussion
    A    district      court's     ruling     under    Rule   15(a)   that
    amendment would be futile "means that the complaint, as amended,
    would fail to state a claim upon which relief could be granted."
    Glassman v. Computervision Corp., 
    90 F.3d 617
    , 623 (1st Cir. 1996)
    (citing 3 Moore's Federal Practice ¶ 15.08[4], at 15–80 (2d ed.
    1993)).3         While   we    review     Rule     15(a)   rulings   for   abuse   of
    discretion, see, e.g., Nikitine v. Wilmington Trust Co., 
    715 F.3d 388
    , 389 (1st Cir. 2013), a material error of law constitutes such
    an abuse, and the question whether a motion to amend is futile
    because the amended complaint fails to state a claim upon which
    relief can be granted is a question of law, see Ouch v. Fed. Nat'l
    Mortg. Ass'n, 
    799 F.3d 62
    , 65 (1st Cir. 2015).                  Hence, our review
    in this case is actually de novo.
    In performing this review, we, like the district court,
    confront a proposed complaint that covers 123 pages and features
    3 To be more precise, a futility finding could also mean that
    the proposed complaint would require dismissal for other reasons,
    such as lack of subject-matter jurisdiction under Rule 12(b)(1).

    extensive single-spaced excerpts.                  D'Agostino devotes most of his
    pleading to establishing in excessive detail that the defendants
    said and did things that they knew were false or improper, and to
    critiquing the Onyx and Axium devices.                          At the same time, the
    pleading offers hints of numerous theories for tying the alleged
    improprieties and defects to false claims.                      D'Agostino's briefs on
    appeal call for us to consider two of those theories for his claims
    concerning Onyx, and two for his claims concerning Axium.
    A.     Onyx Fraudulent Inducement Claims
    D'Agostino's          principal        claim     relating        to      the
    government's payment for the use of MTI's Onyx device rests on an
    allegation that MTI made three fraudulent representations to the
    FDA    in       seeking    approval     to     market    Onyx.      Specifically,         the
    defendants disclaimed uses for the device they later pursued,
    overstated the training they later provided, and omitted critical
    safety information about the molecule, including its failure in
    the Enteryx device.              The FDA, however, made none of the payments
    at issue in this lawsuit.                    Rather, CMS made the payments by
    reimbursing physicians who performed procedures using Onyx and
    hospitals         where    such   procedures       took    place.      "FCA      liability
    attaches to a 'false or fraudulent claim for payment or approval'
    or    to    a    'false    record      or    statement    material    to     a    false    or
    fraudulent claim.'" United States ex rel. Kelly v. Novartis Pharm.
    Corp.,      
    827 F.3d 5
    ,    14    (1st    Cir.    2016)     (quoting       31    U.S.C.
    - 12 -
    § 3729(a)(1)(A)–(B)). To link those CMS payments to the fraudulent
    representations allegedly made to the FDA, D'Agostino notes that
    FDA approval is a precondition to CMS reimbursement for use of a
    medical device, and argues that the fraudulent representations
    allegedly made by MTI to the FDA "could have" influenced the FDA
    to grant that approval.
    We    reject   this    argument     because    alleging    that   the
    fraudulent representations "could have" influenced the FDA to
    approve Onyx falls short of pleading a causal link between the
    representations made to the FDA and the payments made by CMS.                  If
    the representations did not actually cause the FDA to grant
    approval it otherwise would not have granted, CMS would still have
    paid   the     claims.      In   this    respect,    D'Agostino's      fraudulent
    inducement theory is like a kick shot in billiards where the cue
    ball "could have" but did not in fact bounce off the rail, much
    less hit the targeted ball.
    D'Agostino tries to rebut this conclusion by relying on
    the    FCA's      materiality      standard.        Under   that   standard,    a
    representation made to secure a payment is material if it has "a
    natural tendency to influence, or [is] capable of influencing, the
    payment or receipt of money or property."              31 U.S.C. § 3729(b)(4).
    He reasons that as long as MTI's representations at issue "could
    have" influenced the FDA to grant approval, the representations
    were material.
    - 13 -
    This argument may well misconstrue the FCA's materiality
    standard.   It is a "demanding" standard.    Universal Health Servs.,
    Inc. v. United States, 
    136 S. Ct. 1989
    , 2003 (2016).          Moreover,
    the FCA requires that the fraudulent representation be material to
    the government's payment decision itself.         
    Id. at 2002–04.
      The
    fact that CMS has not denied reimbursement for Onyx in the wake of
    D'Agostino's allegations casts serious doubt on the materiality of
    the fraudulent representations that D'Agostino alleges.         
    Id. at 2003–04
    ("[I]f the Government regularly pays a particular type of
    claim in full despite actual knowledge that certain requirements
    were violated, and has signaled no change in position, that is
    strong evidence that the requirements are not material.").
    In   any   event,   even   if   the    alleged   fraudulent
    representations were material as defined by the FCA, the elements
    of D'Agostino's fraudulent inducement claims include not just
    materiality but also causation; the defendant's conduct must cause
    the government to make a payment or to forfeit money owed.          See
    United States ex rel. Westrick v. Second Chance Body Armor Inc.,
    
    128 F. Supp. 3d 1
    , 18 (D.D.C. 2015) (holding that a plaintiff
    asserting fraudulent inducement claims must demonstrate "not only
    that the omitted information was material but also that the
    government was induced by, or relied on, the fraudulent statement
    or omission" (quoting United States ex rel. Thomas v. Siemens AG,
    
    991 F. Supp. 2d 540
    , 569 (E.D. Pa. 2014))), reconsideration granted
    - 14 -
    in part on other grounds sub nom. United States v. Second Chance
    Body Armor Inc., No. 04-CV-280, 
    2016 WL 3033937
    (D.D.C. Feb. 11,
    2016); see also, e.g., United States ex rel. Main v. Oakland City
    Univ., 
    426 F.3d 914
    , 916 (7th Cir. 2005) ("The [FCA] requires a
    causal   rather    than   a     temporal   connection      between   fraud   and
    payment.").     See generally 1 John T. Boese, Civil False Claims and
    Qui Tam Actions §§ 2.01[A][3], 2.05 (4th ed. 2016).                  If the FDA
    would have approved Onyx notwithstanding the alleged fraudulent
    representations, then the connection between those representations
    to the FDA and a payment by CMS relying on FDA approval disappears.
    The defect in D'Agostino's claim is not a mere flaw in
    the complaint's choice of words. In the six years since D'Agostino
    surfaced the alleged fraud, the FDA has apparently demanded neither
    recall nor relabeling of Onyx--this notwithstanding the agency's
    option to impose postapproval requirements, 21 C.F.R. § 814.82(a),
    its   clear    prerogative      to   suspend    approval    temporarily,     
    id. § 814.47(a),
    and its broad authority to withdraw approval, 
    id. § 814.46(a).
         In particular, when the FDA concludes that it has
    been misled because an "application contained or was accompanied
    by an untrue statement of a material fact," it can commence an
    "informal"      hearing   and    withdraw      its   approval   allowing     the
    marketing of a device.           See 21 U.S.C. § 360e(e).            In such an
    instance, it acts with the benefit, where appropriate, of "advice
    - 15 -
    on scientific matters from a panel or panels [of experts] under
    section 360c."    
    Id. The FDA's
    failure actually to withdraw its approval of
    Onyx in the face of D'Agostino's allegations precludes D'Agostino
    from resting his claims on a contention that the FDA's approval
    was fraudulently obtained.   To rule otherwise would be to turn the
    FCA into a tool with which a jury of six people could retroactively
    eliminate the value of FDA approval and effectively require that
    a product largely be withdrawn from the market even when the FDA
    itself sees no reason to do so.     The FCA exists to protect the
    government from paying fraudulent claims, not to second-guess
    agencies' judgments about whether to rescind regulatory rulings.
    See 
    D'Agostino, 153 F. Supp. 3d at 539
    ("Surely, where the FDA was
    authorized to render the expert decision on . . . use and labeling,
    it, and not some jury or judge, is best suited to determine the
    factual issues and what their effect would have been on its
    original conclusions." (quoting King v. Collagen Corp., 
    983 F.2d 1130
    , 1140 (1st Cir. 1993) (Aldrich, J., concurring))).
    The collateral effects of allowing juries in qui tam
    actions to find causation by determining the judgment of the FDA
    when the FDA itself has not spoken are akin to those practical
    effects that counsel in favor of not allowing state-law fraud-on-
    the-FDA claims.    See Buckman Co. v. Plaintiffs' Legal Comm., 
    531 U.S. 341
    , 349–51 (2001).   If jurors in a single qui tam case could
    - 16 -
    determine     precisely          what     representations        were   essential     to
    approval, which experts to believe, and how the FDA interpreted
    submissions    made     to   it,        some    potential     applicants   who     would
    otherwise seek approval for new products might be deterred, others
    might swamp the FDA with more data than it wants, and the "FDA's
    responsibility        to         police        fraud     consistently      with      the
    Administration's judgment and objectives" might be undercut.                         
    Id. at 350.
    Practical problems of proof also inform our conclusion.
    How would a relator prove that the FDA would not have granted
    approval    but   for      the    fraudulent         representations    made   by    the
    applicant?     Would competing experts read someone's mind?                       Whose?
    What if former officials no longer in government were of one view,
    and current officials of another?                   These and similar questions all
    support our position that the absence of some official agency
    action confirming its position and judgment in accordance with the
    law renders D'Agostino's fraud-on-the-FDA theory futile.
    The    United         States       as    amicus   curiae    agrees      that
    D'Agostino's      fraudulent            inducement      theory    "necessarily      asks
    whether [the] FDA would have made a different decision absent the
    fraud."    The United States does request that we reject any reading
    of the district court's opinion as implying that a fraudulent
    inducement claim would not lie even if fraudulent representations
    "actually caused [the] FDA to approve or clear the device."
    - 17 -
    We do not read the district court's carefully crafted
    opinion that way.       Its holding does not, in our view, hinge on
    rejecting or accepting the position of the United States, and
    neither does ours.         Nor are we saying that the FCA is in this
    context preempted by the Federal Food, Drug, and Cosmetic Act, 21
    U.S.C. §§ 301–399f.     We hold only that causation is an element of
    the fraudulent inducement claims D'Agostino alleges and that the
    absence of official action by the FDA establishing such causation
    leaves   a   fatal   gap    in    this   particular     proposed   complaint.
    Certainly some official action by the FDA confirming that its
    approval     was   actually      procured    by   the   alleged    fraudulent
    representations would fill that particular gap in the proposed
    complaint.      Whether it would suffice to sustain the proposed
    complaint we need not decide.
    We do recognize that, should a valid FCA claim exist if
    the FDA withdrew its approval for a product upon discovering fraud,
    our   ruling    today   would     pose   a   theoretical    risk   that   the
    whistleblowing relator might be deprived of his or her bounty by
    a government intent on doing so. This is because the relator would
    need to alert the FDA--to secure withdrawal of approval--before
    the relator could allege causation.          In theory, the government in
    such an instance might first file an FCA action itself, thereby
    arguably precluding the whistleblower from qualifying for a share
    of the recovery under 31 U.S.C. § 3730(d).            As a practical matter,
    - 18 -
    though, this risk is small, and it does not warrant eliminating
    causation as an element of the claim.              As the United States notes,
    instances in which fraudulent representations "masked problems
    that are so serious that [the] FDA would have (for example)
    withheld or withdrawn its approval" are "likely rare."                  Moreover,
    if such a case actually arises, there is no logical reason why the
    government itself (in a case involving what the FDA finds to be
    the fraudulent procural of approval) would want to proceed in a
    manner      that   deprives   the    whistleblower       of   a   bounty,   thereby
    reducing the incentive for future potential whistleblowers aware
    of fraud on the FDA.4
    In any event, the FDA approved Onyx, and has never
    withdrawn that approval.           D'Agostino therefore cannot establish a
    causal link between the alleged fraudulent representations made to
    the   FDA    and   the   payment    of    claims   for   reimbursement      by   the
    government.
    B.    Onyx "Training Program" Claims
    That leaves, with respect to Onyx, D'Agostino's theory
    that the defendants caused the submission of false claims by
    encouraging medically unnecessary and dangerous uses of Onyx by
    physicians who did not attend the training program offered by the
    4The whistleblower in such a scenario, as an original source
    of the information, would trump any copycats who tried to first
    file suit after the FDA publicly disclosed its actions. See 31
    U.S.C. § 3730(e)(4)(A)(i)–(ii).
    - 19 -
    defendants.      Undergirding this theory is the fact that Medicare
    excludes from coverage claims involving procedures that "are not
    reasonable and necessary for the diagnosis or treatment of illness
    or injury."      42 U.S.C. § 1395y(a)(1)(A).      D'Agostino's proposed
    complaint incorporates the statement of a neurosurgeon and leading
    Onyx user, who opines that it is never "medically reasonable or
    medically necessary for an untrained physician to use Onyx in
    procedure [sic] involving a live human being," as such use "creates
    an exceedingly dangerous situation for the patient."        According to
    D'Agostino, the defendants therefore caused the submission of
    false claims by "fail[ing] to provide the physician training that
    the FDA required as a condition of approval usage, and subsequently
    induc[ing] those untrained doctors to use Onyx anyway."             This
    theory, rather than targeting every Onyx claim, attacks the subset
    of   claims    seeking   reimbursement   for   procedures   performed   by
    physicians whom the defendants did not train.
    We evaluate the sufficiency of these allegations under
    Federal Rule of Civil Procedure 9(b), which provides that, "[i]n
    alleging fraud or mistake, a party must state with particularity
    the circumstances constituting fraud or mistake."           Fed. R. Civ.
    P. 9(b).      More precisely, Rule 9(b) requires a relator to allege
    with particularity the who, what, when, where, and how of the
    fraud.     United States ex rel. Ge v. Takeda Pharm. Co., 
    737 F.3d 116
    , 123 (1st Cir. 2013).        Furthermore, allegations limited to
    - 20 -
    describing the defendant's scheme and intent are insufficient,
    "[b]ecause FCA liability attaches only to false claims."               
    Id. at 124
    (citing United States ex rel. Karvelas v. Melrose-Wakefield
    Hosp., 
    360 F.3d 220
    , 225 (1st Cir. 2004), abrogated on other
    grounds by United States ex rel. Gagne v. City of Worcester, 
    565 F.3d 40
      (1st   Cir.    2009)).    Thus,   the   allegations    must    also
    establish    that    the    fraudulent    conduct    actually     caused   the
    submission of false claims to the government for payment.                  
    Id. (citing United
    States ex rel. Rost v. Pfizer, Inc., 
    507 F.3d 720
    ,
    732–33 (1st Cir. 2007), overruled in part by Allison Engine Co. v.
    United States ex rel. Sanders, 
    553 U.S. 662
    (2008)).             As a general
    matter, a relator does this by alleging with particularity examples
    of actual false claims submitted to the government.             
    Karvelas, 360 F.3d at 232
    –33.     By doing so, the relator conveys that if the facts
    alleged are true, the filing of a false claim is not merely a
    possibility, but rather, necessarily occurred.           Alternatively, in
    appropriate circumstances, a relator may instead allege "factual
    or statistical evidence to strengthen the inference of fraud beyond
    possibility."       United States ex rel. Duxbury v. Ortho Biotech
    Prod., L.P., 
    579 F.3d 13
    , 29 (1st Cir. 2009) (quoting 
    Rost, 507 F.3d at 733
    ).        See, e.g., United States ex rel. Escobar v.
    Universal Health Servs., Inc., 
    780 F.3d 504
    , 515 (1st Cir. 2015),
    overruled on other grounds by 
    136 S. Ct. 1989
    (2016) (holding that
    particular allegations concerning one patient were sufficient
    - 21 -
    because they arose from a "systematic failure" that necessarily
    "infected" other claims with fraud).
    Applying   these    rules,   the   district   court   found   the
    proposed     complaint's    allegations     insufficient,    citing    their
    failure to identify any specific false claim submitted to the
    government for reimbursement.       
    D'Agostino, 153 F. Supp. 3d at 536
    n.38.    In response, D'Agostino repeats the argument he made to the
    district court, pointing to allegations in his proposed complaint
    that two physicians who did not attend the defendants' training
    program performed a total of approximately seventy procedures
    using Onyx, and that "well over 50%" of these physicians' patients
    were     insured   under   government     health   plans.     So,     reasons
    D'Agostino, the odds are very high that at least some bills were
    submitted to and paid by the government for use of Onyx by
    untrained physicians.       And since the device label calls for use
    only by trained physicians, the use by untrained physicians was
    both off-label and, in the opinion of an expert retained by
    D'Agostino, not medically necessary.
    There are several problems with this line of reasoning.
    First, and most simply, while the FDA-approved label for Onyx does
    indeed    restrict   use   to   "physicians     with   neurointerventional
    training," and refers users to MTI "for information on training
    courses," it contains no requirement that the physician must obtain
    the training from MTI or ev3.       Therefore, D'Agostino's allegation
    - 22 -
    that the defendants did not train these two physicians falls
    materially short of alleging facts showing that they were not
    trained at all.    And if they were indeed otherwise trained,5 the
    use of Onyx would not have been off-label.         For this reason alone,
    D'Agostino's "training program" claims fail.
    Additionally, even if we were to overlook this gap in
    the allegations, the assumption that physicians submitted claims
    for reimbursement merely because many of their patients in general
    were insured under government programs is faulty.           The district
    court noted as much, explaining the distinction between alleging
    that a certain percentage of patients carried government insurance
    and   alleging   that   any   patient   carrying   government   insurance
    underwent a procedure involving the device that resulted in a claim
    for government reimbursement.      
    D'Agostino, 153 F. Supp. 3d at 536
    n.38.     D'Agostino's assumption is particularly faulty because
    seeking reimbursement here would have required the physicians
    knowingly to submit off-label claims if they did indeed lack the
    training the label plainly required.        See 
    Rost, 507 F.3d at 732
    –
    34.
    For each of these reasons, we agree with the district
    court that D'Agostino's "training program" version of his Onyx
    5The proposed complaint alleges that the defendants trained
    at least one physician at each medical facility, including
    presumably the facilities at which each of these two physicians
    worked.
    - 23 -
    claim fails because it does not sufficiently allege the submission
    of a false claim nor does it advance a theory and facts that
    together    create   a   "strong   inference"   that    false    claims    were
    actually filed.      
    Id. at 732.
    C.   Axium Manufacturing Defect Claims
    D'Agostino describes various alleged defects in the
    manufacture of Axium. Instead of identifying specific false claims
    to CMS involving Axium, the proposed complaint seeks to rely on
    what D'Agostino calls a "complete falsity" theory.               This theory
    applies, he argues, when every device is defective, rendering each
    claim for reimbursement involving the product false, and thereby
    "logically obviat[ing] the need for identification of specific
    false claims, because their submission is a virtual certainty."
    This case presents no need to decide whether such a
    theory is tenable.       The proposed complaint simply does not allege
    facts making it plausible that all Axium devices--or even most--
    were defective.       It alleges only that "certain lots of Axium"
    contained    manufacturing     defects   that   caused     the    device     to
    malfunction when the surgeon tried to use it.                   The proposed
    complaint does not give the number or percentage of Axium devices
    that suffered these manufacturing defects.             It does identify by
    hospital, surgeon, date, and (sometimes) Axium generation and lot
    number a dozen or so surgeries during which the surgeon encountered
    difficulty or failure in trying to deploy the Axium coil.                  Only
    - 24 -
    certain   of    those   instances    are   said    to    involve    defectively
    manufactured devices, and none are alleged to have resulted in any
    particular false claims paid by the government. See, e.g., Hagerty
    ex rel. United States v. Cyberonics, Inc., No. 16-1304, 
    2016 WL 7321224
    , at *4–5 (1st Cir. Dec. 16, 2016) (holding that identifying
    doctors   and    hospitals   whose   patients      had    device    replacement
    surgeries does not establish that any medical provider actually
    submitted claims for government reimbursement).                    Importantly,
    there is no claim here of a latent manufacturing defect that
    manifested itself only after the surgery was completed and the
    claim for reimbursement submitted. To the contrary, the allegation
    is that the defect caused the device to fail as the surgeons tried
    to use it, and thus before any claim for reimbursement might have
    been submitted.     We are therefore left with a proposed complaint
    that neither alleges any specific false claims involving Axium
    devices   with    manufacturing      defects      nor    demonstrates    beyond
    possibility that claims of the type said to be false were actually
    submitted.
    D.   Axium Design Defect Claims
    The proposed complaint also seeks to advance a design
    defect claim.     To do so, it first asserts that Axium was modified
    and improved over time.       It then calls "defective" all earlier
    versions of the device that predated such improvements.                 Even by
    their own conclusory terms, these allegations do not make all
    - 25 -
    devices defective; for example, any device featuring the most
    recent modifications when sold would not be "defective."                 More
    importantly, we agree with the district court that a product (much
    less an FDA-approved medical device) cannot be called defective
    for purposes of establishing falsity in a qui tam case merely
    because new versions of the product contain design improvements.
    See 
    D'Agostino, 153 F. Supp. 3d at 537
    .          Indeed, by that standard,
    most every car sold to the government would be per se defective.
    III.   Conclusion
    None    of   the   claims    in    D'Agostino's   fourth     amended
    complaint is adequately pled, so his request for leave to file
    that complaint was properly denied as futile.               A fortiori, the
    lesser included factual recitation set forth in the third amended
    complaint fails as well.       We therefore have no need to consider
    the   district     court's    alternative        reasons    for      rejecting
    D'Agostino's     claims.      The     district    court's    order     denying
    D'Agostino's motion to amend the complaint is affirmed.
