Viking Therapeutics experienced a 38% drop in share prices following disappointing mid-stage trial results for its obesity treatment VK2735, which reported only a 12.2% mean weight loss. The unfavorable market reaction highlights skepticism regarding the drug's future amid increasing competition from Novo Nordisk and Eli Lilly, both of which are solidifying their dominance in the obesity and diabetes markets. While Novo Nordisk faces its own setbacks with a revised sales outlook, it continues to pursue strategic acquisitions and partnerships, leaving Viking struggling to maintain relevance in a rapidly evolving space.
