Novo Nordisk A/S (NVO) shares climbed 4.06% to $38.15 on Wednesday after new regulatory developments in the United States. The U.S. Food and Drug Administration issued another letter regarding the company’s Ozempic advertising practices. At the same time, the agency targeted telehealth firms promoting compounded GLP-1 drugs, supporting sector momentum.
FDA Flags Ozempic Campaign Claims
The FDA sent Novo Nordisk an untitled letter dated February 26 regarding a digital Ozempic advertisement. The letter focused on content from the “There’s Only One Ozempic” campaign launched in January. Regulators stated that the ad misrepresented the drug’s efficacy through its presentation.
The advertisement highlighted Ozempic’s approved uses, including lowering A1C and reducing certain cardiovascular and kidney risks. The FDA stated that the ad could imply that all Type 2 diabetes patients qualify for every listed indication. In reality, cardiovascular and kidney risk reductions apply only to patients with specific existing conditions.
Regulators acknowledged that the ad included full indication details in onscreen text. However, the agency stated that the visual disclaimer did not correct the broader impression created by the voiceover. The FDA also criticized the delayed presentation of risk information until after the main storyline concluded.
Prior Wegovy Letter Adds to Scrutiny
The February notice followed a separate FDA letter issued three weeks earlier concerning Wegovy advertising. In that case, regulators challenged suggestions that the Wegovy pill represented an advancement over other GLP-1 therapies. The agency stated that no clinical evidence demonstrated superiority over competing drugs.
The earlier letter focused on a television spot that implied improved performance compared to other GLP-1 medications. Regulators determined that the claims lacked adequate substantiation. As a result, the agency requested corrective action to prevent misleading impressions.
Novo Nordisk stated that it takes regulatory feedback seriously and continues responding to agency concerns. The company reaffirmed its commitment to accurate and balanced advertising standards. Meanwhile, Ozempic remains one of the most widely prescribed GLP-1 treatments globally.
FDA Targets Telehealth Compounded GLP-1 Promotions
Separately, the FDA issued warning letters to 30 telehealth companies over compounded GLP-1 drug promotions. The agency stated that several firms marketed products as generic versions of brand-name drugs without authorization. Regulators emphasized that compounded drugs do not hold FDA approval status.
The warning letters referenced compounded versions of semaglutide and tirzepatide marketed under alternative branding. The FDA noted that companies promoted these products as substitutes for approved therapies, including those developed by Novo Nordisk and Eli Lilly. Authorities required written responses from recipients within 15 working days.
The enforcement action marked the second wave of letters since the FDA expanded oversight of pharmaceutical advertising in September. The agency reported sending thousands of compliance notices in recent months. Citi Research indicated that the intensified regulatory environment increased the significance of the latest letters.
Novo Nordisk shares rose more than 4% as markets responded to the broader crackdown. The move reflected support for branded manufacturers amid tighter scrutiny of compounded competitors. Consequently, the stock extended its steady intraday uptrend while regulatory oversight of GLP-1 promotions intensified.
