IN THE UNITED STATES DISTRICT COURT FOR THE EASTERN DISTRICT OF PENNSYLVANIA

MAYOR AND CITY COUNCIL : OF BALTIMORE ON BEHALF OF : ITSELF AND ALL OTHERS SIMILARLY : SITUATED : : CIVIL ACTION NO. 23-0828 v. : : MERCK SHARP & DOHME CORP. :

McHUGH, J. August 28, 2024 MEMORANDUM This is an antitrust class action alleging that Defendant Merck Sharp & Dohme Corporation (Merck) has engaged in illegal conduct that forecloses competition in a significant portion of the rotavirus vaccine market. Plaintiff Mayor and City Council of Baltimore (Baltimore) is a third- party payor that paid for all or part of the purchase price of vaccines, including Defendant Merck’s RotaTeq vaccine, pursuant to its obligations under its self-funded health insurance plan. Baltimore has moved to amend its Complaint, and in addition to opposing that motion, Merck has simultaneously filed a Motion to Strike Class Action Allegations in the Complaint pursuant to Federal Rule of Civil Procedure 23(d)(1)(D). ECF 57. Because Baltimore is correct that its suggested changes to the class definition eliminate redundancies, and because it is too early to rule on the ascertainability of the class, I will grant Baltimore’s Motion to Amend and deny Merck’s Motion to Strike Class Action Allegations. I. Relevant Background The factual allegations in this case are set forth in significant detail in my prior memorandum issued on November 20, 2023. ECF 32. With discovery underway, Baltimore seeks to amend its Complaint to: (1) clarify certain ambiguities that the identified by the court in its opinion on Merck’s motion to dismiss; (2) amend the class definition; and (3) withdraw its jury demand. Mot. to Amend 2-3, ECF 55.1 Merck counters that the proposed changes to the class definition would be futile and would not cure the Complaint of a fatal flaw: ascertainability of the class. Def.’s Opp’n to Mot. to Amend 6-10, ECF 56/59. Merck also files a Motion to Strike Class

Action Allegations in the Complaint, arguing that there is “no administratively feasible mechanism” to sufficiently identify class members, and as a result, the parties should not be burdened with continued class certification proceedings at the end of discovery. Def.’s Mot. Strike 8-9. II. Standard of Review A. Motion to Amend After an answer has been filed, the plaintiff needs either leave of court or consent from the opposing party to amend. Fed. R. Civ. P. 15(a). The Federal Rules of Civil Procedure require that a court “should freely give leave when justice so requires.” Fed. R. Civ. P. 15(a)(2). The Third

Circuit has instructed, however, that a district court may deny a motion to amend when allowing the amendment would be futile. Shane v. Fauver, 213 F.3d 113, 115 (3d Cir. 2000). B. Motion to Strike Class Allegations Under Federal Rule of Civil Procedure 23(d)(1)(D), the court may issue orders that require “the pleadings be amended to eliminate allegations about representation of absent persons.” Courts, however, “rarely grant motions to strike under Rule 23(d)(1)(D) prior to class discovery, doing so only where ‘no amount of additional class discovery will alter the conclusion’ that the class is not maintainable.” Goode v. LexisNexis Risk & Info. Analytics Grp., Inc., 284 F.R.D. 238,

1 Once a jury trial has been properly demanded, the trial must be by jury unless the parties stipulate otherwise. Fed. R. Civ. P. 39(a). Because Merck has not consented to Baltimore’s request to withdraw its jury demand, Baltimore may not withdraw its demand, which Baltimore concedes. See Pl.’s Mot. to Amend Reply Br. 10, ECF 66. 244 (E.D. Pa. 2012) (DuBois, J.) (citing Thompson v. Merck & Co., No. 01-1004, 2004 WL 62710 (E.D. Pa. Jan. 6, 2004) (Weiner, J.)); see also Salyers v. A.J. Blosenski, Inc., --- F. Supp. 3d ---, 2024 WL 1773368, *2 (E.D. Pa. Apr. 24, 2024) (Beetlestone, J.). III. Discussion

Baltimore defines the class as: [A]ll entities that (i) are third-party payors that (ii) have purchased, paid, and/or provided reimbursement for some or all of the purchase price of RotaTeq; (iii) for consumption by their members, employees, insureds, participants, or beneficiaries (iv) in one of the Repealer Jurisdictions (v) after March 3, 2019, and (vi) do not fall within any of the two exclusion categories.

Pl.’s Mot. to Amend Reply Br. 5, ECF 66. The class definition originally listed four exclusion categories, which the proposed amendment would reduce to two. The substantive change proposed is the removal of the following exclusion category: “(c) fully insured health plans (i.e., health plans that purchased insurance from another third-party payor covering 100% of the plan’s reimbursement obligations to its members).” See ECF 55, Ex. 2 - Redline of First Am. Compl. 44, Merck argues that removing this category would be futile in that doing so “creates an intractable ambiguity in the class definition, because as the Third Circuit has recognized [in Niaspan], fully-insured health plans do not bear the risk of loss for any over-payment for medical benefits, and as a result, such plans are not appropriate class members.”2 Def.’s Opp’n to Mot. Amend 8. Merck goes on to argue that regardless of the exclusion, a class cannot be certified because there is no administratively feasible mechanism to identify class members without

2 “In a self-insured health plan, the plan pays for its beneficiaries’ prescription drugs using funds provided by the sponsor and by its beneficiaries. Because a self-insured sponsor bears the financial risk for the health benefits of its participants, it is an end-payor of prescription drugs. Conversely, in a fully insured plan, the plan sponsor pays premiums to a health insurer, and that insurer bears the financial responsibility for the payments of prescription drugs, making it, rather than the plan sponsor, the end-payor.” In re Niaspan Antitrust Litig., 67 F.4th 118, 122 (3d Cir. 2023). individualized fact-finding, as demonstrated by In re Niaspan Antitrust Litig., 67 F.4th 118, 122 (3d Cir. 2023). In Niaspan, end-payors of prescription drugs alleged that brand-name drug manufacturers entered into anticompetitive “pay-for-delay” agreements to delay the introduction of certain

generic prescription drugs, inflating prices for consumers. In re Niaspan Antitrust Litig., 67 F.4th 118, 121 (3d Cir. 2023). At the class certification stage, the District Court rejected the class for its failure to demonstrate ascertainability, which the Third Circuit affirmed. Id. at 122. Specifically, Niaspan held that because the plaintiffs were unable to propose any viable and administratively feasible method to exclude fully insured health plans from the putative class, the class did not meet the ascertainability requirement and could not be certified. Id. at 125. Niaspan differs from this case in several important respects. First, Niaspan was decided at the class certification stage, after the close of discovery. Second, the data set available to the plaintiffs in Niaspan derived from Pharmacy Benefit Managers (PBM), and the Court found that “PBMs cannot identify class members because their data does not show whether, in any given
