Opinion for the Court filed by Circuit Judge GINSBURG.
The plaintiff-appellants in these four antitrust class actions are wholesale purchasers of Tiazac (extended-release Diltiazem Hydrochloride, hereinafter Diltiazem HC1), a controlled-release drug for hypertension and angina. They alleged that Biovail Corporation, which manufactures Tiazac, misused a patent to keep off the market a generic equivalent manufactured by Andrx Pharmaceuticals, Inc., in violation of federal and state antitrust laws. The district court entered summary judgment for Bio-vail, which we affirm.
I. Background
The would-be manufacturer of a “generic” bioequivalent to a previously approved “branded” drug may file an abbreviated new drug application (ANDA) with the Food and Drug Administration while the branded drug is purportedly protected by a patent.

See generally
21 U.S.C. § 355(j); 21 C.F.R. § 314.94;
Ranbaxy Labs. Ltd. v. Leavitt,
Tentative approval of an ANDA does not entail the right to market the subject drug. See §§ 314.105(d), 314.107(b)(3)(v) (“Tentative approval of an application does not constitute ‘approval’ ” under FDCA “and cannot, absent a final approval letter from the agency, result in an effective approval”). Nor does it guarantee final approval, which may depend upon an “additional review of the application” by the FDA. 21 U.S.C. § 355(j)(5)(B)(iv)(II)(dd)(BB);' see also 21 C.F.R. § 314.107(b)(3).
In June 1998 Andrx filed an ANDA seeking approval to market Diltiazem HC1 under the name Taztia; Andrx included a Paragraph IV certification both challenging the validity of Biovail’s U.S. Patent No. 5,529,791 (filed Sept. 23, 1994) (the '791 patent), which Biovail claimed protected the formula for Tiazac, and asserting Taz-tia would not infringe that patent. Biovail sued Andrx in federal district court in Florida, thereby extending the statutory stay for up to 30 months. In March 2000,
*860
the district court determined Andrx’s product would not infringe Biovail’s patent,
Biovail Corp. v. Andrx Pharms., Inc.,
In September 2000 the FDA “tentatively]” approved Andrx’s ANDA, noting that Biovail’s pending appeal prevented it from giving final approval at that time. * The agency went on to explain that, if and when Andrx prevailed on appeal, the FDA would have to be “assured there is no new information that would affect whether final approval should be granted.”
On January 8, 2001, with its appeal still pending, Biovail claimed its newly acquired U.S. Patent No. 6,162,463 (filed Apr. 28, 1998) (the '463 patent) also protected Tia-zac, and the FDA asked Andrx for its position with regard to that patent. On February 13 the Federal Circuit affirmed the judgment for Andrx in the '791 patent litigation,
Meanwhile, Andrx had begun to encounter problems manufacturing its version of Diltiazem HC1. In December 2000, shortly after having received tentative approval from the FDA, Andrx identified problems in its methodology for testing Taztia for dissolution in the human body. In January 2001 Andrx manufactured a new batch of the drug, which it initially found satisfactory pursuant to a new testing methodology, but on May 18, 2001 the Company discovered that samples from the new batch also failed to dissolve as required. Andrx eventually rejected that entire batch because the manufacturing process was faulty, and continued to encounter manufacturing problems into 2003. Because of those problems, the FDA did not finally approve Andrx’s ANDA until April 2003 — a full year after Biovail had withdrawn its claim that the '463 patent covered its drug.
Much as Andrx had done in its suit against Biovail,
see
Biovail moved for summary judgment in two of the four present class actions on the ground that, regardless whether Biovail had violated the antitrust laws, the plaintiffs could not show Biovail had caused them any harm. The district court agreed,
Twin Cities Bakery Workers Health & Welfare Fund v. Biovail Corp.,
Nos. Civ.A. 01-2197, Civ.A. 03-2075,
Seeking to avoid the same fate, the plaintiffs in the fourth action,
Louisiana Wholesale Drug Co. (LWD) v. Biovail Corp.,
Applying its
Twin Cities
ruling to
LWD
without addressing the Rule 56(e) affidavit, the district court entered summary judgment for the defendants insofar as the
LWD
plaintiffs claimed the defendants had prevented the plaintiffs from purchasing Taztia from Andrx; the court held that no reasonable juror could find Biovail’s use of the '463 patent prevented the FDA’s final approval of Andrx’s ANDA.
II. Analysis
The plaintiffs in all four class actions appeal, contending they proffered evidence *862 sufficient to defeat Biovail’s motion for summary judgment. In addition, the LWD plaintiffs argue the district court improperly dismissed the amendment to their complaint as untimely and erroneously failed to address their affidavit seeking further discovery under Rule 56(e).
A. Inability to Purchase Taztia from Andrx (Original Theory)
A plaintiff seeking damages under the antitrust laws must prove the defendant has caused the plaintiff “antitrust injury,” meaning an “injury of the type the antitrust laws were intended to prevent and that flows from that which makes defendants’ acts unlawful.”
Brunswick Corp. v. Pueblo Bowl-O-Mat, Inc.,
Biovail argues, and the district court held, no reasonable juror could conclude Biovail caused the plaintiffs any harm. The plaintiffs submit they presented evidence sufficient for a reasonable juror to find that but for Biovail’s conduct, the FDA would have granted Andrx final approval in February 2001 and that Andrx would have marketed Taztia soon thereafter.

Reviewing the summary judgment
de novo, Galvin v. Eli Lilly & Co.,
In arguing that a reasonable juror could find the FDA would have approved Andrx’s ANDA in February 2001 but for misconduct by Biovail, the plaintiffs first point to the affidavits of Dr. Nicholas Fleischer and Mr. Jeffrey Gibbs, each of whom had once worked for the FDA. The district court, invoking Federal Rules of Evidence 702 (admissibility of expert testimony) and 403 (exclusion of otherwise admissible evidence on ground of unfair prejudice), excluded those affidavits because they were speculative and ungrounded in fact and, in any event, “their value is substantially outweighed by the danger of unfair prejudice or misleading the jury.”
See
The plaintiffs next direct us to decisions of courts they claim determined, in litigation involving Andrx, Biovail, and the FDA, that the agency would have finally approved Andrx’s ANDA in February 2001 but for Biovail’s misuse of the '463 patent,
see Andrx Pharms., Inc. v. Biovail Corp. Int’l,
No. 01-6194-Civ (S.D.Fla. Mar. 6, 2001);
Andrx Pharms., Inc.,
Of the evidence upon which the plaintiffs rely in their brief to this court, we accordingly confine our analysis to the FDA’s tentative approval in September 2000, a February 2001 fax from the FDA to Andrx, the FDA’s filings in the case Andrx brought to compel the agency to withdraw the '463 patent from the Orange Book, and the affidavit of an Andrx employee. * *864 Upon the basis of this evidence, we hold no reasonable juror could conclude that but for Biovail’s misuse of the '463 patent the FDA would have approved Andrx’s ANDA in February 2001.
The plaintiffs maintain the tentative approval of September 2000 demonstrates that, apart from the '463 patent, the only hurdle to final approval was resolution of the '791 patent dispute. That first tentative approval made clear, however, that final approval was also subject to the FDA being “assured there is no new information that would affect whether final approval should be granted.” For that reason, the FDA instructed the applicant, “when you believe that your application may be considered for final approval,” file “[ujpdated information related to labeling or chemistry, manufacturing and controls data, or any other change in the conditions outlined in th[e] abbreviated application.” A reasonable juror would not infer upon the basis of this letter that final approval would have been forthcoming in February 2001.
As Biovail points out, the FDA’s second tentative approval, issued in May 2001, further undermines the plaintiffs’ treatment of the September 2000 tentative approval as tantamount to final approval subject only to the lifting of the statutory stay. The plaintiffs belittle the May 2001 approval as “simply a reaffirmance of the September 2000 approval,” but the record contradicts that contention. The FDA’s letter of May 14, 2001 referred not only to the September 2000 tentative approval but also to several amendments to Andrx’s ANDA that postdated the decision of the Federal Circuit in the '791 patent dispute; had the FDA meant merely to “reaffirm” its previous tentative approval, it could easily have said so. * At best the second tentative approval suggests the FDA could have given final approval of Andrx’s ANDA in May, not February, 2001.
Nor is the FDA’s fax of February 2, 2001 helpful to the plaintiffs. It states only that a division of the FDA “ha[d] completed its review” of the December 2000 amendment (relating to Andrx’s testing methodology) and “ha[d] no further questions at this time,” and even that explicitly “preliminary” observation was made “subject to revision after review of the entire application.” In the same fax the FDA also asked Andrx to “provide a ... certification” as to the '463 patent, but the FDA nowhere suggested the agency would approve Andrx’s ANDA when Bio-vail’s patents were no longer a bar.
The plaintiffs also point out that in the litigation Andrx brought against Biovail and the agency, “FDA briefing demonstrates] that because [Biovail] listed the '463 Patent, Andrx’s ANDA was no longer eligible for final FDA approval in February 2001.” Relatedly, the plaintiffs note that when Andrx filed a statement of undisputed facts in that litigation' — to the effect that only litigation over the '791 *865 patent prevented the FDA’s final approval — the FDA responded that the '463 patent also barred final approval. These documents are unhelpful, however, because they demonstrate only that ending the patent litigation was a necessary condition for the FDA’s final approval; a reasonable juror could not infer from them that it was a sufficient condition. In keeping with applicable law, 21 C.F.R. § 314.107(b); 21 U.S.C. § 355(j)(5)(B)(iii), (j)(5)(B)(iv)(II)(dd)(BB), the FDA’s brief stated only that upon the termination of the litigation Andrx would be “eligible for,” not that it would be “entitled to,” final approval. Similarly, the FDA’s response to Andrx’s statement of undisputed facts does not imply it would have granted final approval but for Biovail’s misuse of the second patent. Nor could it have: The FDA’s final approval was by law subject to Andrx updating its application to the satisfaction of the FDA once the statutory bar was lifted.
The plaintiffs finally rely upon the February 9, 2001 affidavit of Scott Lodin, then the General Counsel of Andrx. When Andrx sought to compel the FDA to remove the '463 patent from the Orange Book, Lodin filed an affidavit stating “the FDA had informed Andrx that it was prepared to grant final approval to Andrx’s ANDA upon the expiration of the 30-month stay period” triggered by Biovail’s first patent infringement case. The Lodin affidavit, however, cites only the tentative approval of September 2000, which we have already determined is an insufficient basis for a reasonable juror to find the FDA would have granted final approval in February 2001; beyond that it is merely conclusory.
Cf. Greene v. Dalton,
We conclude the plaintiffs have not adduced evidence sufficient for a reasonable juror to find the FDA would have approved Andrx’s ANDA in February 2001 but for Biovail’s claim the '463 patent covered Tiazac and Biovail’s subsequent suit for infringement of that patent. The plaintiffs’ original theory of the case, in which they blamed Biovail for their inability to purchase Taztia from Andrx, turned upon the jury being able to make that finding. Accordingly, we affirm the entry of summary judgment in favor of the defendants in all four cases inasmuch as the plaintiffs blame Biovail for their inability to purchase Taztia from Andrx.
B. Inability to Purchase Generic Diltiaz-em HC1 from Biovail (Amended Complaint)
The
LWD
plaintiffs alleged in their amended complaint that Biovail and Forest conspired preemptively to manufacture and distribute their own generic version of Diltiazem HC1 while the '791 patent litigation precluded competitors from entering the market, a scheme they abandoned in late 2000 or early 2001 in favor of misusing the '463 patent to exclude potential competitors.
*
The defendants argue, and the district court held, the complaint does not relate back and does not allege facts sufficient to establish a claim of injury within the limitation period. Reviewing the court’s dismissal
de novo,
while “as-
*866
sum[ing] ‘all the allegations in the complaint are true (even if doubtful in fact),’ ”
Aktieselskabet AF 21. November 2001 v. Fame Jeans Inc.,
(1) Relation Back
Federal Rule of Civil Procedure 15(c)(1)(B) provides: “An amendment ... relates back to the date of the original pleading when ... the amendment asserts a claim ... that arose out of the conduct, transaction, or occurrence set out — or attempted to be set out — in the original pleading.”
See also
Fed.R.Civ.P. 15(c)(2) (2007). The underlying question is whether the original complaint adequately notified the defendants of the basis for liability the plaintiffs would later advance in the amended complaint.
United States v. Hicks,
The LWD plaintiffs alleged for the first time in the amended complaint that Biovail and Forest had conspired to exclude new entrants into the market for generic Dil-tiazem HC1 and (before Biovail acquired the '463 patent) had planned preemptively to capture that market by launching their own generic drug. For prior notice, they point out that their original complaint referred to their inability to purchase “generic versions of Tiazac,” ie., in the plural, and contend the amendment “simply add[ed] detail regarding which generic versions [of Diltiazem HC1] would have been marketed but for Defendants’ scheme.”
As we read their original complaint, however, it did not put Biovail and Forest sufficiently on notice the plaintiffs might be claiming the defendants’ decision not to sell their own generic Diltiazem HC1 violated the antitrust laws. The original complaint chronicles the tale of a single firm, Biovail, bent upon preventing the FDA from granting final approval of the generic drug proposed by Andrx (and perhaps others), but it did not allege Forest had engaged in any specific misconduct; Forest was made a defendant solely because, as Biovail’s exclusive distributor, it “benefit-ted from [Biovail’s] wrongful conduct to extend the Tiazac monopoly” unlawfully. The amended complaint alleges for the first time that Biovail and Forest unlawfully conspired to extend their lawful monopoly, that they planned preemptively to introduce their own generic Diltiazem HC1, and that they unlawfully abandoned that plan in favor of misusing the '463 patent to prevent the FDA from approving the applications of their would-be generic competitors. Although the original and amended claims have some elements and some facts in common, the whole thrust of the amendments is to fault both Biovail and Forest, and to fault them for conduct different from that identified in the original complaint. Consequently, the amended complaint does not relate back.
*867 (2) Adequacy of the Amendment to the Complaint
The
LWD
plaintiffs filed their amended complaint on June 1, 2005; because that complaint does not relate back to the filing of the original complaint, the
LWD
plaintiffs, who claim the defendants violated § 2 of the Sherman Act, 15 U.S.C. § 2, must allege the defendants injured them during the four year period starting June 1, 2001, or state facts sufficient reasonably to give rise to an inference of such an injury.
See
§ 4B of the Clayton Act, 15 U.S.C. § 15b (providing any suit for damages under the federal antitrust laws “shall be forever barred unless commenced within four years after the cause of action accrued”);
see also Twombly,
On appeal the
LWD
plaintiffs argue that, but for Biovail’s acquisition of the '463 patent, Biovail and Forest in February 2001 would have entered into long-term contracts to sell to wholesalers, including the plaintiffs, generic Diltiazem HC1 beyond June 1, 2001 and the plaintiffs were injured because they were unable to purchase generic drugs from the defendants pursuant to those hypothetical contracts. They made no similar allegation, however, in the amended complaint, their opposition to Biovail’s motion to dismiss, or their request under Rule 56(e) for further discovery. At oral argument, counsel for the
LWD
plaintiffs was unable to say when, if ever, they made this argument in the district court and as far as we can tell they never did. Absent a showing that “ ‘injustice might otherwise result,’ ” and the plaintiffs offer none, we do not entertain an argument made for the first time on appeal.
Ben-Kotel v. Howard Univ.,
As the defendants argue, without the allegation that Biovail and Forest would have entered into long-term contracts to sell wholesalers generic Diltiazem HC1, the LWD plaintiffs have no basis upon which to claim that, but for Biovail’s acquisition of the '463 patent, the defendants would have sold them generic Diltiazem HC1 after June 1, 2001. Because, as we have held, the LWD plaintiffs cannot show Andrx would have sold Diltiazem HC1 pri- or to May 2003, when Andrx received final approval and long after they allege either defendant had engaged in any misconduct, it follows that the defendants would have faced no competition until then. * There is no provision of law that would have required Biovail and Forest to sell or continue selling a generic version of Diltiazem HC1 in competition with Biovail’s branded product once it became clear, as it would have done in early 2001, that Andrx could not get FDA approval to enter the market. Nor does the complaint advance any fact suggesting Biovail and Forest would have done so. (The plaintiffs do not argue on appeal that any firm other than Andrx sought to enter the market.) These gaps are fatal to the plaintiffs’ case.
In sum, the factual allegations of the LWD plaintiffs’ amended complaint, taken as true, are inadequate to make out a timely action under the antitrust laws. Therefore, we affirm the dismissal of the amended complaint.
*868 C. The Rule 56(e) Affidavit
Finally, we turn to the LWD plaintiffs’ objection to the failure of the district court to address their Rule 56(e) affidavit before entering judgment. The LWD plaintiffs sought to discover from Andrx any communications between it and the FDA tending to show the FDA would have given final approval of Andrx’s ANDA in February 2001. They also sought to discover from Andrx information regarding what it would have done had it obtained final approval from the FDA in February 2001 but subsequently discovered problems manufacturing the drug, and from Biovail and Forest information relating to their alleged plan preemptively to sell a generic version of Tiazac.
If the district court’s inattention to the plaintiffs’ affidavit was an error, then it was surely harmless. 28 U.S.C. § 2111;
Colbert v. Potter,
III. Conclusion
With respect to their original theory of the case, the plaintiffs have not shown a reasonable juror could find the FDA would have granted Andrx final approval in February 2001 and, without such proof, they are unable to show Andrx was ready and able to market generic Diltiazem HC1 at any time prior to the expiration of the statutory stay. Therefore, the plaintiffs are unable to establish the facts required to make out antitrust injury.
The amendment to the LWD complaint was both untimely and insufficient because (1) the amended complaint claiming that Biovail and Forest conspired to prevent the plaintiffs’ purchase of generic Diltiaz-em HC1 from Biovail does not relate back to the filing of their original complaint and (2) the plaintiffs have not alleged facts sufficient to establish Biovail and Forest would have harmed them within the four-year limitation period for antitrust claims, which began to run in June 2001. Nor does their affidavit for additional discovery under Rule 56(e) require a remand.
Accordingly, the judgment of the district court is in all respects
Affirmed.
Notes
The FDA maintains in its Orange Book a list of the patents that, according to the manufacturer, protect each branded drug.
The FDA may not approve an application that does not account for a claimed patent, see 21 U.S.C. § 355(j)(2)(A)(vii), (j)(4)(J), or that "contains an untrue statement of material fact,” § 355(j)(4)(K).
The statute provides that the stay terminates when "the court” determines the patent at issue is invalid or would not be infringed. 21 U.S.C. § 355(j)(5)(B)(iii). The FDA at that time took the position that the stay would expire only upon the resolution of any appeal. After
Torpharm v. Shalala,
No. Civ.A. 97-1925,
Plaintiffs make no argument specific to the law of any state.
In principle, the plaintiffs could establish antitrust injury by showing that, but for Biovail's misuse of the '463 patent, they could have purchased generic Diltiazem HC1 from Andrx at any time during the pendency of the stay caused by the '463 patent. The plaintiffs, however, have not argued that Andrx would have obtained approval from the FDA and been ready to market the drug at any time after February 2001 but before the expiration of the statutory stay — a wise strategy in view of the problems Andrx encountered tiying to manufacture Taztia during that period. Therefore, it is crucial to the plaintiffs’ case, as counsel acknowledged at oral argument, that they make the showing stated in the text.
Not all the plaintiffs invoked all the evidence upon which they all now rely; because we find the totality of competent evidence insuffi *863 cient to defeat the defendants’ motion for summary judgment, however, we need not concern ourselves with the effort of certain of the plaintiffs to rely on appeal upon evidence they did not adduce before the district court.
In addition to the evidence described in the text, the plaintiffs refer in their brief to the FDA's "conclu[sion] in writing ... that [Andrx's] generic drug would be approved, but for the ... infringement suit.” No such conclusion is to be found in the record of this case, however, and the plaintiffs do not provide the statement itself but instead quote the opinion in
Andrx Pharmaceuticals, Inc.,
175
*864
F.Supp.2d at 1366. We disregard that purported "evidence”; if the underlying evidence exists and is in the record of the cited case, then the plaintiffs, who have access to that record, should have produced it.
Cf. Cmty. Hosps. of Cent. Cal.
v.
NLRB,
The plaintiffs assert in a footnote in their reply brief that the various amendments were minor matters (relating to product labeling) that would not have prevented final approval in February 2001, but that assertion is as con-clusory as it is untimely.
See United States v. Whren,
The plaintiffs do not allege the defendants engaged in any misconduct after April 2002, when Biovail dropped its claim that the '463 patent protected Tiazac.
Rule 12(b)(6) requires us to assume the truth of the facts alleged in the complaint but not to disregard our own holding that the plaintiffs cannot show Andrx would have competed with Biovail but for the latter company's misconduct. Cf. 5A Charles Alan Wright & Arthur R, Miller, supra, § 1357 ("Numerous cases ... have allowed consideration of matters incorporated by reference or integral to the claim, items subject to judicial notice, matters of public record, orders, items appearing in the record of the case, and exhibits attached to the complaint whose authenticity is unquestioned; these items may be considered by the district judge without converting the motion into one for summary judgment”).
In any event, the plaintiffs have not explained why they would need additional discovery: It is undisputed that the LWD plaintiffs have had access to the full record of the litigation in Florida; Andrx obviously would have introduced in that case any document responsive to this request in its attempt to have the FDA remove the '463 patent from the Orange Book.
