MEMORANDUM OPINION

I.

Plaintiff Avadel CNS Pharmaceuticals, LLC (“Avadel”) is a pharmaceutical company

specializing in the development of LUMRYZ, 1 a drug for the treatment of narcolepsy. In

December 2020, Avadel submitted a new drug application (“NDA”) to the FDA, pursuant to

Section 505(b)(2) of the Federal Food, Drug, and Cosmetic Act (“FDCA”), seeking approval for

LUMRYZ. The active ingredient in LUMRYZ is sodium oxybate, which is the same active

ingredient used in two narcolepsy drugs—XYREM and XYWAV—presently approved for

marketing by Defendant-Intervenor Jazz Pharmaceuticals, Inc. (“Jazz”).

In support of an NDA, a Section 505(b)(2) applicant must file either (1) a “Patent

Certification,” which triggers a statutorily required notice to an existing patentholder of the

1 LUMRYZ is the proposed brand name for the drug at issue, the investigational name for which is “FT218.” An investigational new drug product like FT218 cannot be marketed in the United States, 21 U.S.C. §§ 331(a), 355(d), but the court will refer to the drug by its proposed brand name throughout the opinion for ease of identification. potential impact on the holder’s intellectual property rights, or (2) a “Patent Statement,” which

represents that no existing patents listed in the FDA’s patent database are implicated by the new

drug. Avadel initially filed a Patent Statement with its NDA indicating that its application did not

implicate any listed patents. The FDA then sought additional information from Avadel to justify

its grounds for submitting a Patent Statement.

On May 24, 2022, the FDA rejected Avadel’s Patent Statement. It advised instead that

Avadel must submit a Patent Certification because Avadel’s application sought approval of a

method of use of the sodium oxybate drug that was already claimed by an existing method-of-use

patent held by Jazz (the “Patent Decision”). On June 6, 2022, Avadel submitted the requested

Patent Certification but under protest. That filing triggered a statutory notice requirement that

compelled Avadel to inform Jazz about a potential patent infringement. Jazz then filed a patent

infringement action in the District of Delaware. Avadel filed a statutorily created counterclaim in

response that seeks to have Jazz’s patent removed from the FDA patent database.

Before this court, Avadel asserts two claims: first, that Federal Defendants’ 2 decision

requiring Avadel to submit a Patent Certification violated the Administrative Procedure Act

(“APA”), and second, that Federal Defendants have unreasonably delayed approval of LUMRYZ.

Avadel seeks a preliminary injunction or an expedited entry of judgment releasing it from the

obligation to file a Patent Certification and an order requiring the FDA to rule on its NDA. See

Pl.’s Mot. for Prelim. Inj. or Summ. J., ECF No. 2 [hereinafter Pl.’s Mot.]. Federal Defendants

have cross-moved for summary judgment, as has Intervenor-Defendant Jazz. See Fed. Defs.’

Cross-Mot. for Summ. J., ECF No. 25 [hereinafter Fed. Defs.’ Cross-Mot.]; Def.-Int.’s Cross-Mot.

2 Defendants in this matter are Secretary of Health and Human Services Xavier Becerra, in his official capacity; the U.S. Department of Health and Human Services; the U.S. Food and Drug Administration (“FDA”), and FDA Commissioner Robert M. Califf, in his official capacity (collectively, “Federal Defendants”).

2 for Summ. J. and Opp. to Pl.’s Mot. for Prelim. Inj., ECF No. 27 [hereinafter Def.-Int.’s Cross-

Mot.].

As discussed below, the court holds that Avadel is not entitled to relief under the APA

because of the availability of adequate alternative relief—namely, the ongoing, statutorily

prescribed patent infringement and counterclaim proceedings in the District of Delaware.

Accordingly, Federal Defendants’ and Intervenor-Defendant’s Cross-Motions for Summary

Judgment are granted, and Plaintiff’s Motion for Preliminary Injunction or Summary Judgment is

denied.

II.

Section 505(b)(2) of the FDCA provides a streamlined pathway for approval of drugs that

are based on the same active ingredient as a previously approved drug. To facilitate notice to

existing patentholders that their intellectual property rights may be impacted by an NDA, a

Section 505(b)(2) applicant must file either a “Patent Certification” or a “Patent Statement” in

support of their NDA. Whether an applicant must file a Statement versus a Certification depends

on, as relevant here, whether an existing patent claims the proposed use for the drug at issue.

21 U.S.C. § 355(b)(2)(A), (B). 3

Patent Certification. A Patent Certification must be filed when an NDA does implicate an

existing patent listed in the “Orange Book”—an FDA database that contains summary information

about active drug patents submitted by patentholders. See 21 U.S.C. § 355(b)(2)(B). If a method-

of-use patent claims a use of the drug for which the applicant seeks approval, then the applicant

must file a Patent Certification that explains why the proposed use would not infringe on the

existing patent or why the existing patent is invalid. Id. § 355(b)(2)(A)(i)–(iv).

3 A Patent Certification also is required “with respect to each patent which claims the drug” on which the applicant’s NDA is based. 21 U.S.C. § 355(b)(2)(A). That provision is not at issue in this case.

3 In addition, when filing a Patent Certification, the NDA applicant must provide notice to

the original patentholder of the application and “include a detailed statement of the factual and

legal basis of the opinion of the applicant that the patent is invalid or will not be infringed.” Id.

§ 355(b)(3)(D)(ii). Such notice triggers a 45-day period within which the original patentholder

can bring a patent infringement claim. See id. § 355(c)(3)(C). If the original patentholder timely

files suit, the FDA is barred from approving the NDA for up to 30 months, unless the court shortens

the time or the patent litigation resolves sooner. See id. The FDCA also creates a unique right of

action for the NDA applicant. The applicant may “assert a counterclaim seeking an order requiring

the [patentholder] to correct or delete” an Orange Book listing. Id. § 355(c)(3)(D)(ii)(I). That

claim of relief is not available in any other civil action or proceeding. Id. § 355(c)(3)(D)(ii)(II).

Patent Statement. A Patent Statement is appropriately filed when an NDA does not

implicate a method-of-use patent listed in the Orange Book. See 21 U.S.C. § 355(b)(2)(A). The

FDCA provides that a Patent Statement may be filed only when an existing “method of use

patent . . . does not claim a use for which the applicant is seeking approval.”

See 21 U.S.C.
