Could Viking Therapeutics Disrupt the Weight-Loss Space?
Viking Therapeutics (VKTX) shares surged 35% after positive Phase II trial results for VK2735, a weight-loss drug with a dual agonist approach. The trial showed participants maintained significant weight loss with reduced injection frequency. Novo Nordisk (NVO) faces competition and patent expirations, with shares down 70% since mid-2024. Viking's market cap is $5 billion, and its stock is still 60% below 2024 highs.
