Eli Lilly announced positive top-line Phase 3 results from its ACHIEVE-1 trial for orforglipron in adults with type 2 diabetes on April 17, 2025. The investigational once-daily oral GLP-1 pill successfully achieved its primary and key secondary endpoints. This marks a significant step forward for Eli Lilly in the oral incretin market.

The data indicated that orforglipron demonstrated similar efficacy and safety relative to weekly injectable semaglutide, a leading GLP-1 receptor agonist. This outcome reinforces the potential for oral therapies to compete effectively with injectable treatments in managing type 2 diabetes and related metabolic conditions.

For Viking Therapeutics, this development from a major competitor validates the market for oral GLP-1/GIP agonists but also intensifies the competitive landscape. It establishes a high benchmark for efficacy and tolerability that Viking's own oral VK2735 will need to meet or exceed to differentiate itself in the market.
