Viking Therapeutics saw its stock jump by 28% on Thursday after the company announced it would be advancing its experimental weight loss injection, VK2735, into a late-stage trial earlier than anticipated. This move positions Viking closer to entering the lucrative GLP-1 market, which analysts project could grow to $150 billion by the end of the decade.
Viking’s accelerated timeline was influenced by feedback from the Food and Drug Administration (FDA), allowing the San Diego-based biotech firm to bypass an additional mid-stage trial. The company plans to meet with the FDA in the fourth quarter to finalize the design and timing of the phase three trial, potentially shaving a year off the drug’s development timeline. Analysts now estimate the drug could launch as early as 2029.
VK2735, a weekly injection that targets GLP-1 and GIP hormones, demonstrated promising results in a phase two trial, with patients experiencing up to 14.7% body weight loss after 13 weeks. Viking also plans to test a monthly version of the injection, which could offer a more convenient alternative to Eli Lilly’s Zepbound and Novo Nordisk’s Wegovy, both of which are administered weekly.
In response to Viking’s announcement, shares of major competitors Eli Lilly and Novo Nordisk closed lower, down 4% and 3% respectively, reflecting market concerns over potential new competition in the weight loss and diabetes treatment space.
Viking Therapeutics is also exploring an oral version of VK2735, which showed a 3.3% weight loss compared to a placebo in an early-stage trial. As Viking pushes forward, its entry into the GLP-1 market could intensify competition among drugmakers vying for a share of this rapidly expanding sector.
