Amgen produces apremilast and markets it as a phosphodiesterase-4 (PDE4) inhibitor, which is used for treating psoriasis and related conditions, under the brand name Otezla®. The 638, 101, and 541 patents cover Otezla. Sandoz submitted an Abbreviated New Drug Application (ANDA) seeking FDA approval to market a generic version of apremilast. Amgen’s predecessor brought a Hatch-Waxman suit, asserting that Sandoz’s generic product would infringe the patents.The Federal Circuit affirmed holdings that claims 3 and 6 of Amgen’s 638 patent and claims 1 and 15 of Amgen’s 101 patent had not been shown to be invalid as obvious and that claims 2, 19, and 21 of its 541 patent”) were shown to be invalid as obvious in light of prior art. The court noted that varying a dose in response to the occurrence of side effects is a well-known, standard medical practice that may well lead to a finding of obviousness. View "Amgen Inc. v.

The Butter! Spray is a butter-flavored vegetable oil dispensed in pump-action squirt bottles with a spray mechanism. The front label on the product states that the Butter! Spray has 0 calories and 0 grams of fat per serving. Plaintiffs are a class of consumers who brought their lawsuit against the then-manufacturer, Unilever United States, Inc., contending that the product’s label makes misrepresentations about fat and calorie content based on artificially low serving sizes. The district court found that Plaintiffs failed to plausibly allege that Butter! Spray was not a “spray type” fat or oil under Food and Drug Administration (FDA) regulations. The district court further held that the FDCA preempted plaintiffs’ serving size claims.   The Ninth Circuit affirmed the district court’s Fed. R. Civ. P. 12(b)(6) dismissal. The panel held that, as a matter of legal classification, Butter! Spray was a “spray.” In common parlance, a “spray” refers to liquid dispensed in the form of droplets, emitted from a mechanism that allows the product to be applied in that manner. In addition, the notion that Butter! Spray could be housed under the FDA’s legal classification for “butter” is implausible. The panel also rejected Plaintiffs’ argument that Butter! Spray is a “butter substitute” based on how it is marketed so it should be treated as “butter” for serving size purposes, too. The court explained that because Plaintiffs’ challenge to the Butter! Spray serving sizes would “directly or indirectly establish” a requirement for food labeling that is “not identical” to federal requirements, the FDCA preempts their serving size claims.

The Food and Drug Administration (“FDA”) approved mifepristone to be marketed with the brand name Mifeprex under Subpart H (the “2000 Approval”). In January 2023, FDA approved a modified REMS for mifepristone, lifting the in-person dispensing requirement.  Plaintiffs (physicians and physician organizations) filed a suit against FDA, HHS, and a several agency heads in the official capacities. Plaintiffs challenged FDA’s 2000 Approval of the drug and also requested multiple grounds of alternative relief for FDA’s subsequent actions. Plaintiffs moved for a preliminary injunction ordering FDA to withdraw or suspend (1) FDA’s 2000 Approval and 2019 Generic Approval, (2) FDA’s 2016 Major REMS Changes, and (3) FDA’s 2021 Mail-Order Decision and its 2021 Petition Denial of the 2019 Citizen Petition. The district court entered an order staying the effective date of the 2000 Approval and each of the subsequent challenged actions.   The Fifth Circuit granted Defendants’ motions for a stay pending appeal. The court wrote that at this preliminary stage, and based on the court’s necessarily abbreviated review, it appears that the statute of limitations bars Plaintiffs’ challenges to the Food and Drug Administration’s approval of mifepristone in 2000. However, Plaintiffs brought a series of alternative arguments regarding FDA’s actions in 2016 and subsequent years. And the district court emphasized that its order separately applied to prohibit FDA’s actions in and after 2016 in accordance with Plaintiffs’ alternative arguments. As to those alternative arguments, Plaintiffs’ claims are timely. Defendants have not shown that Plaintiffs are unlikely to succeed on the merits of their timely challenges. For that reason, Defendants’ motions for a stay pending appeal are denied in part. View "Alliance Hippocratic Medicine v. FDA" on Justia Law

Rotigotine is used to treat Parkinson’s disease, which causes difficulty swallowing and slow transit times through intestines, which can frustrate oral treatments. Transdermal therapeutic systems deliver drugs through the patient’s skin and avoid those complications. In 2007, UCB invented and marketed Neupro®, the first FDA-approved patch treatment for Parkinson’s disease. Original Neupro® is covered by several UCB patents, including the Muller patents, which claim priority to an application filed in 1999. The Muller patents are listed in the FDA’s “Orange Book,” as covering reformulated Neupro®.In 2013, Actavis submitted an Abbreviated New Drug Application (ANDA) for FDA approval of a generic transdermal rotigotine patch. UCB sued for infringement. The district court granted UCB an injunction preventing approval of Actavis’s ANDA until March 2021, when the Muller patent expired. In 2018 UCB filed the patent application that matured into the 589 patent, claiming priority from a provisional application filed in 2009, entitled “Polyvinylpyrrolidone for the Stabilization of a Solid Dispersion of the Non-Crystalline Form of Rotigotine.” UCB again filed suit, asserting the 589 patent, to delay FDA approval of a generic for nine additional years.The district court found that the Muller patents anticipate all asserted claims and that the asserted claims would have been obvious in view of multiple prior art references, including the Muller patents. The Federal Circuit affirmed the judgment of invalidity of the 589 patent. The district court’s fact findings on overlapping ranges, teaching away, unexpected results, and commercial success are not clearly erroneous, View "UCB, Inc. v. Actavis Laboratories UT, Inc." on Justia Law

In 2014, Merck and Bayer entered a Stock and Asset Purchase Agreement (SAPA) whereby Merck sold, and Bayer purchased, Merck’s consumer care business and consumer care product lines, including the Claritin, Coppertone, Dr. Scholl’s, and Lotrimin foot powder product lines. The transaction closed in October 2014. Bayer paid Merck more than $14 billion. After the transaction closed, both companies were the subject of lawsuits alleging injuries arising from consumers’ use of talc-based products that Merck used in foot powder product lines sold to Bayer; asbestos allegedly contained in talcum powder has caused fatal cancers.The Delaware Court of Chancery dismissed Merck’s suit in which it argued that Bayer breached the SAPA by refusing to assume liability for the claims. Both companies, as sophisticated participants in the pharmaceutical industry, understood that consumer products businesses face potential liability for torts associated with the sale of such consumer products. The SAPA clearly and unambiguously provides that Merck indefinitely retained substantive liability for the product liability claims related to products sold before the transaction closed. Merck attempted to argue that its liability for the product liability claims ceased in 2021; the court found that interpretation contrary to the SAPA's clear and unambiguous terms. Bayer’s interpretation of the SAPA is the only reasonable one. View "Merck & Co., Inc. v. Bayer AG" on Justia Law

Liposomal bupivacaine is a nonopioid pain medication that Pacira manufactures under the name EXPAREL; it is a local anesthetic administered at the time of surgery to control post-surgical pain. As of 2020, EXPAREL sales represented nearly all of Pacira’s total revenue. Pacira complains that the defendants, the American Society of Anesthesiologists, its journal, its editor, and authors published statements in a variety of forms, conveying their view that EXPAREL is “not superior” to standard analgesics or provides “inferior” pain relief.The Third Circuit affirmed the dismissal of Pacira’s suit for trade libel. Opinion statements are generally nonactionable. A “fair and natural” reading of the statements at issue shows that these are nonactionable subjective expressions. Pacira’s allegations boil down to disagreements about the reliability of the methodology and data underlying the statements; “a scientific conclusion based on nonfraudulent data in an academic publication is not a ‘fact’ that can be proven false through litigation.” Pacira failed to identify any aspect of the Articles, a Continuing Medical Education program, or a Podcast that “bring their conclusions outside the protected realm of scientific opinion.” View "Pacira Biosciences Inc v.

The Supreme Court affirmed the order of the circuit court dismissing Appellants' complaint alleging that the Arkansas Medical Marijuana Commission had granted a marijuana cultivation license to a corporate entity that had been dissolved, holding that the circuit court correctly dismissed this appeal on the merits.Appellants, existing cultivation license holders, challenged the Commission's decision to allegedly grant a license to a dissolved corporate entity, arguing that the circuit court erred by holding that it lacked subject-matter jurisdiction and wrongly held that Appellants lacked standing. The Supreme Court reversed, holding that the circuit court (1) erred by not finding that it lacked subject-matter jurisdiction and that Appellants lacked standing; but (2) properly dismissed the complaint because it failed to allege facts sufficient to mount the State's sovereign immunity defense.

The Supreme Court affirmed in part, reversed in part and vacated in part the judgment of the circuit court holding that Bristol-Myers Squibb and Sanofi had violated Hawai'i's Unfair or Deceptive Acts or Practices law (UDAP) by misleading the public about the safety and efficacy of their anitplatelet drug, Plavix, holding that remand was required.The circuit court concluded that Defendants misled Hawai'i consumers by failing to warn them that Plavix was less effective for poor responders, granted the State's motion for partial summary judgment, and imposed an $834 million penalty. The Supreme Court (1) reversed the circuit court's deceptive acts or practices holding, holding that the summary judgment ruling circumscribed Defendants' ability to present a full defense and affected the penalty award, requiring a new trial; (2) affirmed the holding that Defendants committed unfair acts under UDAP; and (3) held that Defendants' procedural arguments failed.

Generic versions of ranitidine-containing antacids are sold under the brand name Zantac. In 2019, after an independent laboratory found “significant quantities of NDMA,” a known carcinogen in ranitidine-containing antacids, the FDA issued a public alert. Some manufacturers voluntarily recalled their products. In 2020, the FDA “request[ed that] manufacturers withdraw all prescription and [OTC] ranitidine drugs from the market immediately.”CEH, a nonprofit corporation, sued under Proposition 65, the Safe Drinking Water and Toxic Enforcement Act of 1986, Health and Safety Code 25249.5, alleging that the generic-drug defendants continued to expose individuals to NDMA without clear and reasonable warnings regarding the carcinogenic hazards. The trial court dismissed the generic defendants without leave to amend, citing preemption by the federal Food, Drug, and Cosmetic Act, 21 U.S.C. 301. The court determined that the generic-drug defendants cannot give a Proposition 65 warning without violating the federal requirement that the generic version of a drug have the same “labeling” as the brand-name version. The court of appeal affirmed that dismissal. Although not all methods of publicly communicating a warning about a drug necessarily qualify as “labeling,” CEH fails to identify any method by which the generic-drug defendants could provide a warning that would satisfy both Proposition 65 and the federal duty of sameness.

Gilead filed an inter partes review (IPR) petition challenging claims of the University of Minnesota’s 830 patent, directed to phosphoramidate prodrugs of nucleoside derivatives that prevent viruses from reproducing or cancerous tumors from growing. The U.S. Patent and Trademark Office Patent Trial and Appeal Board found certain claims unpatentable as anticipated by the asserted prior art.The Federal Circuit affirmed. There is no “ipsis verbis” written description disclosure sufficient to support the patent’s claims, 35 U.S.C. 112. The court referred to “a compendium of common organic chemical functional groups, yielding a laundry list disclosure of different moieties for every possible side chain or functional group. Indeed, the listings of possibilities are so long, and so interwoven, that it is quite unclear how many compounds actually fall within the described genera and subgenera.” The court found no violations of the Administrative Procedures Act and rejected the University argument that sovereign immunity barred IPR proceedings against it.
