Viking Therapeutics IncViking begins phase 1 trial for VK3019, a novel dual amylin-calcitonin agonist for obesity, expanding its pipeline beyond GLP-1.
Viking Therapeutics has launched a phase 1 trial of VK3019, a dual amylin and calcitonin receptor agonist for obesity, marking its first candidate outside the GLP-1 pathway. The study, announced on June 24, enrolls adults with a body mass index of 30 or above and tests an injectable formulation. Viking aims to target a new appetite-regulating hormone, but larger rivals Eli Lilly and Novo Nordisk are far ahead with their own amylin programs. Eli Lilly's eloralintide showed up to 20.1% weight loss in phase 2 and is now in phase 3, while Novo Nordisk's cagrilintide delivered 11.8% weight loss in phase 2 and entered phase 3 in late 2025, with a combination therapy CagriSema already submitted for FDA review. Viking also holds VK2735, a GLP-1/GIP dual agonist in phase 3, and could pair it with VK3019, though Lilly is already testing a similar combination of eloralintide and tirzepatide in phase 3.

Eli Lilly and CompanyViking's new amylin drug could eventually compete with Eli Lilly's eloralintide, but Lilly is far ahead in phase 3.
