Amgen Shares Rebound 4.1% Amid Optimism Over Differentiated OLPASIRAN Program
Amgen (AMGN) shares have surged by 4.1% on September 22, 2026, after a recent selloff due to concerns about the Lp(a) drug class.
An analysis suggests that investors are now warming up to the view that Amgen's olpasiran program may still be differentiated from rival programs.
The rebound is also attributed to commercial and regulatory progress for Imdelltra, which could improve uptake of the treatment.
