The legal battle between two pharmaceutical giants escalated Monday as Bayer filed a lawsuit against Johnson & Johnson, accusing its competitor of false advertising regarding the effectiveness of a prostate cancer treatment.
Filed in Manhattan federal court, the lawsuit claims Johnson & Johnson’s marketing campaign for its drug Erleada contains misleading claims that patients experienced a “51% reduction in risk of death” when choosing Erleada over Bayer’s competing medication, Nubeqa.
Bayer contends that Johnson & Johnson’s assertions are not only false but also damaging to the German drugmaker’s reputation and product trust. At the heart of the dispute is J&J’s representation that its comparative data adhered to “rigorous” U.S. Food and Drug Administration standards.
The complaint argues that Johnson & Johnson’s analysis is fundamentally flawed because it compared dissimilar patient groups. According to Bayer, most Nubeqa patients in the study received the drug off-label, creating what it termed “irremediable selection bias” that renders any claims of superiority unreliable. Further compounding the alleged statistical manipulation, Bayer noted that Johnson & Johnson’s study included five times more patients than the Nubeqa comparison group.
“By invoking FDA authority to lend unwarranted credibility to scientifically flawed analyses, J&J has misled patients and healthcare providers,” Bayer stated in its complaint. The company is pursuing punitive and triple damages, recovery of profits allegedly gained through false advertising, and an injunction to halt further misleading marketing.
Johnson & Johnson, headquartered in New Brunswick, New Jersey, defended its marketing practices and study methodology. “Litigation does not change data,” a company spokesperson said via email. “Our analysis was designed to meet rigorous guidance on real-world evidence, and this legal action demonstrates Bayer’s obvious misunderstanding of methodological frameworks and real-world evidence principles.”
The lawsuit highlights the intense competition in the multibillion-dollar oncology pharmaceutical market. Both drugs represent significant revenue sources for their respective companies. Nubeqa generated approximately 1.63 billion euros ($1.92 billion) in sales during the first nine months of 2023, while Erleada sales reached $2.62 billion during roughly the same period, with full-year sales totaling $3.57 billion.
In a novel aspect of the complaint, Bayer claimed that artificial intelligence is amplifying Johnson & Johnson’s allegedly false claims. The company pointed to Google search results related to Erleada, Nubeqa, and mortality risk, arguing that AI tools are spreading “unsubstantiated messages about the risk of dying with Nubeqa” to patients seeking treatment information.
The dispute takes place against the backdrop of a serious public health concern. Prostate cancer remains one of the most common cancers among men in the United States, with the National Cancer Institute reporting approximately 313,780 new diagnoses and 35,770 deaths from the disease in 2023.
Pharmaceutical advertising has faced increasing scrutiny in recent years, with regulators and consumers demanding greater transparency and accuracy in marketing claims. The FDA maintains strict guidelines regarding comparative drug advertising, particularly when claims involve mortality benefits.
This case highlights the complex intersection of medical marketing, clinical research methodology, and the growing influence of artificial intelligence in healthcare information dissemination. It also underscores the high stakes involved when competing treatments target the same patient population, especially for life-threatening conditions like prostate cancer.
The court has not yet scheduled hearings on Bayer’s request for an injunction against Johnson & Johnson’s marketing campaign. Industry analysts will be watching closely, as the outcome could influence how pharmaceutical companies market their products and utilize real-world evidence in competitive claims going forward.
