Amgen Discontinuing Future Development Of AMG 513; To Continue Phase 1 Trial Of AMG 513 In Adults With Obesity

Aug 4, 2026, 8:59 PM UTC · Primary ticker $AMGN

Amgen announced it is discontinuing the future development of its obesity drug, AMG 513, though a Phase 1 trial will continue to completion for enrolled participants. This decision indicates a setback in Amgen's pipeline for obesity treatments, potentially impacting its long-term growth prospects in this therapeutic area.

Amgen has decided to cease future development of AMG 513, an obesity drug candidate. This is significant because it removes a potential future revenue stream and growth driver from Amgen's pipeline in the highly competitive and lucrative obesity market. While a Phase 1 trial will conclude for existing participants, the lack of further development signals a strategic shift or a lack of promising results that would justify continued investment. This news primarily affects Amgen (AMGN) by potentially lowering its long-term growth outlook in the obesity space, which is a key area of investor interest. For traders, the short-term implication is a potential negative reaction to AMGN stock due to pipeline contraction, while the long-term implication is a reassessment of Amgen's competitive position in the obesity drug market.
