MEMORANDUM OPINION

Plaintiff Novartis Pharmaceuticals Corporation brings this action against the Secretary of Health and Human Services (“HHS”) and the Commissioner of the Food and Drug Administration (“FDA”) for injunctive relief. Novartis alleges that FDA unlawfully approved an application by MSN Pharmaceuticals Inc. and MSN Laboratories Private Ltd. (“MSN”) to market a generic version of Novartis’s heart failure medication ENTRESTO (generic combination sacubitril/valsartan). MSN intervened as defendant. Before the Court is the plaintiff’s motion for a temporary restraining order and/or preliminary injunction to stay FDA’s approval of MSN’s drug application. Dkt. 3. For the reasons that follow, the Court will deny Novartis’s motion for a preliminary injunction.

I. BACKGROUND A. Statutory Background To obtain FDA approval to market a new, brand-name drug, a manufacturer must submit a New Drug Application (NDA) containing clinical data from studies demonstrating that the drug is safe and effective. See 21 U.S.C. § 355(b)(1). The brand-name manufacturer often holds patents for the drug product, as well as patents for methods-of-use of the drug. FDA maintains a publication, colloquially referred to as the “Orange Book,” which lists active pharmaceutical patents including method-of-use patents.

After the period of patent exclusivity expires for a drug product, other manufacturers may obtain FDA approval to market a generic version through an Abbreviated New Drug Application (ANDA). See 21 U.S.C. § 355(j). ANDAs need not include independent clinical data of safety or effectiveness; the applicant need only establish the generic drug is “the same as” a previously approved brand-name reference drug. See id. § 355(j)(2). To demonstrate “same”-ness, the applicant must prove the generic is (1) the pharmaceutical equivalent of, (2) labeled for the same conditions of use as, and (3) bioequivalent to the reference drug. See id. § 355(j)(2)(A). ANDA applicants that seek approval for generic drugs with use-cases listed in the Orange Book must file either a “paragraph IV certification” challenging the validity of listed patents, id. § 355(j)(2)(A)(vii)(IV), or a “section viii statement” certifying the applicant does not seek to market the drug for use-cases covered by patent, id. § 355(j)(2)(A)(viii). Section viii ANDA applicants may “carve out” patented use-cases from the generic’s label, subject to statutory and regulatory constraints.

FDA regulations supplement the statutory scheme by, as relevant here, clarifying the “same labeling” requirement. Id. § 355(j)(2)(A). FDA regulations provide that a generic label may differ

from a reference label when a drug is produced by a “different manufacturer[],” in order to address differences in marketing exclusivity or patent rights:

Such differences between the applicant's proposed labeling and labeling approved for the reference listed drug may include differences in expiration date, formulation, bioavailability, or pharmacokinetics, labeling revisions made to comply with current FDA labeling guidelines or other guidance, or omission of an indication or other aspect of labeling protected by patent or accorded exclusivity under section 505(j)(5)(F) of the Federal Food, Drug, and Cosmetic Act.

21 C.F.R. § 314.94(a)(8)(iv). However, the labeling differences may “not render the proposed drug product less safe or effective than the listed drug for all remaining, nonprotected conditions of use.” Id. § 314.127(a)(7).

B. Factual Background In 2015, FDA approved the heart failure drug ENTRESTO. See Pl.’s Ex. A (ENTRESTO Labeling) § 1.1, Dkt. 1-1. Since that time, Novartis has marketed ENTRESTO without generic competition and has generated over $10.5 billion in revenue in the United States. Compl. ¶ 79, Dkt. 1. Novartis still owns several ENTRESTO-related method-of-use patents that hinder generic entry in two ways. First, Novartis patents No. 9,517,226; No. 9,937,143; and No. 11,135,192 purport to cover use of the drug to treat a certain population of chronic heart failure patients, classified as those with “preserved ejection fraction.” See id. ¶ 40. Second, Novartis patent No. 11,058,667 purports to cover a specific dosing regimen of the drug. See id. ¶ 39.

In September 2022, Novartis submitted a citizen petition requesting that FDA refrain from approving any ENTRESTO-related ANDA that would carve out labeling language related to those patented methods. Pl.’s Mot. for TRO at 10–11. Novartis raised essentially the same arguments that it does in the instant motion, namely, that the two carve outs violate both the Federal Food Drug and Cosmetic Act and FDA’s regulations and present safety and efficacy risks. On July 24, 2024, FDA denied Novartis’s citizen petition in a 45-page letter detailing why the carveouts would

be proper under statute and regulation and would not risk the drug’s safety or efficacy. Pl.’s Ex. H, Dkt. 1-8. That same day, FDA approved MSN’s ANDA No. 213748 for generic sacubitril/valsartan, which contains the disputed carveouts. The carveouts are described below.

1. Indication Carveout ENTRESTO’s indication currently reflects that it is approved to treat all adult patients with chronic heart failure. Chronic heart failure patients are sometimes classified by a diagnostic criterion called left ventricular ejection fraction (LVEF)—that is, the ability of the left heart ventricle to pump out blood with each contraction. See Pl.’s Ex. I § 14, Dkt. 1-9. At the time of ENTRESTO’s approval by FDA, reduced ejection fraction patients (HFrEF) were understood to suffer from a more severe form of the disease. Pl.’s Mot. for TRO at 6. ENTRESTO was initially approved based on the results of a clinical trial that enrolled only reduced ejection fraction patients. Id. After ENTRESTO’s approval, Novartis completed another clinical trial evaluating the drug’s effectiveness on patients with only mildly-reduced or normal LVEF—that is, preserved ejection fraction patients. Pl.’s Ex. F (Labeling Carve-Out Citizen Petition) at 7–8, Dkt. 1-6. That trial demonstrated that chronic heart failure patients with preserved ejection fraction (HFpEF) also benefitted from ENTRESTO, albeit less so than reduced ejection fraction patients. Accordingly, in 2021 FDA approved a supplement to ENTRESTO’s indication reflecting the drug’s broader application. See Pl.’s Ex. I § 1.1. ENTRESTO’s indication currently reads:

ENTRESTO is indicated to reduce the risk of cardiovascular death and hospitalization for heart failure in adult patients with chronic heart failure. Benefits are most clearly evident in patients with left ventricular ejection fraction (LVEF)

below normal.

LVEF is a variable measure, so use clinical judgment in deciding whom to treat.

Pl.’s Ex. A § 1.1, Dkt. 1-1.

MSN’s generic label modifies that indication, to carve out the subset of preserved ejection fraction patients covered by Novartis’s patents. The modified label reads:

Sacubitril and valsartan tablets are indicated to reduce the risk of cardiovascular death and hospitalization for heart failure in adult patients with chronic heart failure and reduced ejection fraction.

Left ventricular ejection fraction (LVEF) is a variable measure, so use clinical judgment in deciding whom to treat.

Def.’s Ex. A § 1.1, Dkt. 13-1.

2. Dosing Regimen Carveout ENTRESTO’s label also provides dosing instructions to manage the risks of side effects
