The gastroparesis lawsuits were centralized before Marston in February 2024.<\/p>\n<p>The companies had urged the panel to add the cases to the existing gastroparesis MDL.<\/p>\n<p>There are currently 30 optic neuropathy lawsuits pending in federal court, and more than 40 in state court, court records show. They began hitting dockets after a July 2024 study described the potential risk of the condition associated with the drugs.<\/p>\n<p>There are nearly 3,000 lawsuits over the gastroparesis claims in the MDL, according to court records.<\/p>\n<p>The companies have refuted the claims over gastroparesis and optic neuropathy, arguing in court filings that the risk of gastroparesis is well-publicized and that the companies are unable to change the drugs&#8217; design without the approval of the U.S. Food and Drug Administration.<\/p>\n<p>The case is IN RE: Glucagon-like Peptide-1 Receptor Agonists (GLP-1 RAs) Non-Arteritic Anterior Ischemic Optic Neuropathy Products Liability Litigation, case number 3163.<\/p>\n<p>For the plaintiffs: Christopher Seeger, Parvin Aminolroaya and Max Kelly of Seeger Weiss<\/p>\n<p>For Eli Lilly: Diana Watral of Kirkland &amp; Ellis<\/p>\n<p>For Novo Nordisk: Loren Brown and Lucas Przymusinski of DLA Piper<\/p>\n<p data-testid=\"SignOff\" class=\"text-module__text__0GDob text-module__dark-grey__UFC18 text-module__regular__qJJtA text-module__extra_small__8Buss body-module__full_width__kCIGb body-module__extra_small_body__Bfz20 sign-off-module__text__LQAMP\">Reporting by Diana Novak Jones<\/p>\n<p data-testid=\"Body\" dir=\"ltr\" class=\"text-module__text__0GDob text-module__dark-grey__UFC18 text-module__regular__qJJtA text-module__small__sph8i body-module__base__o--Cl body-module__small_body__gOmDf article-body-module__element__5eCce article-body-module__trust-badge__5mS3f\">Our Standards: <a data-testid=\"Link\" target=\"_blank\" referrerpolicy=\"no-referrer-when-downgrade\" href=\"https:\/\/www.thomsonreuters.com\/en\/about-us\/trust-principles.html\" rel=\"noopener nofollow\" class=\"text-module__text__0GDob text-module__dark-grey__UFC18 text-module__medium__2Rl30 text-module__small__sph8i link-module__link__INqxZ link-module__underline_default__-okuC link-module__with-icon__qlg76\">The Thomson Reuters Trust Principles., opens new tab<\/a><\/p>\n<p><a href=\"https:\/\/www.reutersagency.com\/en\/licensereuterscontent\/?utm_medium=rcom-article-media&amp;utm_campaign=rcom-rcp-lead\" target=\"_blank\" dir=\"ltr\" class=\"button-module__link__A3sD0 button-module__secondary__70gBu button-module__round__QDFgq button-module__w_auto__Sem-F\" data-testid=\"LicenceContentButton\" rel=\"nofollow noopener\">Purchase Licensing Rights<\/a><a data-testid=\"AuthorBioImageLink\" class=\"author-bio-module__author-image__jcaG3\" href=\"https:\/\/www.reuters.com\/authors\/diana-novak-jones\/\" referrerpolicy=\"no-referrer-when-downgrade\" tabindex=\"-1\" rel=\"nofollow noopener\" target=\"_blank\"><\/a><\/p>\n<p data-testid=\"Body\" class=\"text-module__text__0GDob text-module__dark-grey__UFC18 text-module__regular__qJJtA text-module__extra_small__8Buss body-module__base__o--Cl body-module__extra_small_body__Bfz20 author-bio-module__description__9ynkB\">Diana reports on product liability, litigation, mass torts and the plaintiffs&#8217; bar.
