Appeal from the United States District Court for the Central District of California John W. Holcomb, District Judge, Presiding

Argued and Submitted November 18, 2025 Pasadena, California

Before: BYBEE, LEE, and DE ALBA, Circuit Judges. Partial Dissent by Judge LEE.

Plaintiffs-Relators Naresha Moore and Beata Damavandi (“Relators”) appeal the district court’s orders dismissing their first amended complaint. We have jurisdiction under 28 U.S.C. § 1291, and we review the grant of a motion to dismiss de novo. United States v. Allergan, Inc., 46 F.4th 991, 996 (9th Cir. 2022). For the reasons discussed below, we affirm in part, reverse in part, vacate in part, and remand in part.

3 24-5569

1. The district court erred in dismissing Relators’ claims against Regeneron Pharmaceuticals, Inc. and Regeneron Healthcare Solutions, Inc. (jointly, “Regeneron”) under the public disclosure bar. The False Claims Act (FCA) provides that courts “shall dismiss” an FCA suit “if substantially the same allegations or transactions as alleged in the action or claim were publicly disclosed” through certain channels unless the plaintiff is “an original source of the information.” 31 U.S.C. § 3730(e)(4). The bar “seeks to strike a balance between ‘encourag[ing] suits by whistle-blowers with genuinely valuable information, while discouraging litigation by plaintiffs who have no significant information of their own to contribute.’” Allergan, 46 F.4th at 994 (citation omitted). “Whether a particular disclosure triggers the public disclosure bar is a mixed question of law and fact that we review de novo.” United States ex rel. Mateski v. Raytheon Co., 816 F.3d 565, 569 (9th Cir. 2016).

The publicly disclosed information in this case consists of high-level transactional data showing that Regeneron made payments to physicians, sometimes specifying that certain payments were made for things like “Food and Beverage” or “Travel and Lodging.” But those data reveal only “a piece of the puzzle”; they do not clearly show the “full picture” of the allegedly fraudulent scheme, which is filled in by Relators’ allegations about Regeneron’s internal business operations and the substructure underlying those payments. Silbersher v. Valeant Pharms. Int’l, Inc.,

4 24-5569

89 F.4th 1154, 1168 (9th Cir. 2024). For example, one could not glean from the mere fact that payments were made that Regeneron frequently deviated, without justification, from its own tiered system for assigning fair-market value to physician payments, or that reports from both an internal Regeneron audit and an external consulting firm concluded that Regeneron may “be inappropriately compensat[ing]” doctors. Relators further add to the public disclosure that Regeneron used scorecards to track its return on investment in doctors, that it dropped one doctor when his prescription volume went down, and that it capitulated to one doctor’s threat to cancel a speaker event if Regeneron did not pay to stay him in a luxury resort. Nor could one determine from the fact that Regeneron paid doctors certain sums that the programs for which those payments were made were sham programs or that some of them never actually occurred.

Put simply, the existence of the payments may have been public prior to Relators’ lawsuit, but all the most pertinent details surrounding those payments— those that constitute the alleged fraud and indicate Regeneron’s intent to unlawfully induce referrals—were not. See United States v. Hong, 938 F.3d 1040, 1047 (9th Cir. 2019) (concluding that “‘one purpose of the payment’ [must] be to induce future referrals” (citation omitted)). And without those additional details, the public disclosure of payments was not sufficient to “put the government on notice to investigate the alleged fraud before [the relators] filed [their] complaint.” United

States ex rel. Solis v. Millennium Pharms., Inc., 885 F.3d 623, 627 (9th Cir. 2018). Accordingly, the public disclosure bar does not apply to Relators’ claims against Regeneron.
