Alzheimer’s patients have received discouraging news after the release of results from a major study. Novo Nordisk confirmed that its Alzheimer’s treatment did not show a “statistically significant” slowdown in the progression of the illness. Two trials evaluating the company’s weight loss medicine semaglutide in Alzheimer’s disease did not meet their targets, the firm said on Monday, as the drug failed to slow decline compared with a placebo.Testing semaglutide, the active ingredient in Ozempic and Wegovy, for Alzheimer’s had always been viewed as a high-risk attempt, even though research has suggested the drug may influence several processes beyond metabolism. Still, Novo had raised interest in recent weeks by advertising roles connected to Alzheimer’s consumer marketing and medical affairs.Novo Nordisk Says Alzheimer's Drug Trial FailsNovo Nordisk said on Monday that an older oral form of semaglutide did not achieve its main outcome in late-stage trials assessing whether the drug could reduce cognitive decline in people with Alzheimer’s disease, sending its shares down by 10 percent. The development dims expectations that Alzheimer’s could become a major new area for GLP-1 medicines like semaglutide, at a time when Novo is facing stronger competition for its leading products in obesity and diabetes. Treatment choices for Alzheimer’s patients remain limited. The company’s study had been closely followed as a potential sign of whether GLP-1 drugs, widely used for diabetes and weight control, might slow the condition’s advance.The pill tested was Rybelsus, approved only for type 2 diabetes and containing semaglutide, as reported by Reuters.Novo Nordisk: Lottery Ticket FailsThe firm’s Executive Vice President for Product and Portfolio Strategy, Ludovic Helfgott, had earlier described the Alzheimer’s trials as a “lottery ticket,” reflecting both the uncertainty and the considerable promise involved. Alzheimer’s and related dementias affect more than 55 million people worldwide, and no cure exists. “While semaglutide did not demonstrate efficacy in slowing the progression of Alzheimer’s disease, the extensive body of evidence supporting semaglutide continues to provide benefits for individuals with type 2 diabetes, obesity, and related comorbidities,” Chief Scientific Officer Martin Holst Lange said in a statement.The findings from the two early-stage studies, EVOKE and EVOKE+, mark another setback for the Danish company and its new CEO Mike Doustdar. Novo had experienced remarkable success with Ozempic and Wegovy, but slower sales growth and a sharp drop in its stock value led to a leadership shift and significant job cuts.The disappointment adds weight to analysts’ doubts about Novo’s Alzheimer’s plans, with UBS having earlier estimated only a 10 percent likelihood of success.Novo Nordisk: Alzheimer’s Trial Stakes And OutcomeAlzheimer’s, marked by deep cognitive decline, fading memory and changes in behaviour, remains one of the hardest challenges in drug research. Novo had repeatedly acknowledged the uncertainty surrounding these studies. Even so, the possible payoff was significant. Analysts at Morgan Stanley had estimated that a breakthrough could have added up to $5 billion in yearly revenue.“We believed it was important to assess whether semaglutide could offer any benefit,” Chief Scientific Officer Martin Holst Lange said, referring to the drug better known as Ozempic. The treatment did show improvement in certain biological markers connected to Alzheimer’s, but these gains did not lead to a slower progression of the condition.Novo Nordisk Stock: Impact On Competition And Obesity MarketThe company is also working to strengthen its footing in the obesity sector. Any sign that Wegovy could influence the most common form of dementia might have provided an edge over Eli Lilly’s Zepbound in the United States, where competition in this field is intensifying.
