Pfizer Inc. announced that the Phase 3 SPIRE-AI (AutoInjector) trial of the investigational Proprotein Convertase Subtilisin Kexin type 9 inhibitor (PCSK9i) bococizumab administered with a pre-filled pen met its co-primary endpoints: percent change from baseline in low-density lipoprotein cholesterol (LDL-C) reduction at 12 weeks compared to placebo and proportion of patients successfully operating the pre-filled pen. The SPIRE-AI trial is the second study completed of the six SPIRE Phase 3 lipid-lowering studies, and we expect it will be part of the potential regulatory filing for bococizumab.
