Cognitive Function with PCSK9 Inhibitors: A 24-Month Follow-Up Observational Prospective Study in the Real World-MEMOGAL Study

Introduction: The cognitive safety of monoclonal antibody proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) has been established in clinical trials, but not yet in real-world observational studies. We assessed the cognitive function in patients initiating PCSK9i, and differences in c...

Sumario:Introduction: The cognitive safety of monoclonal antibody proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) has been established in clinical trials, but not yet in real-world observational studies. We assessed the cognitive function in patients initiating PCSK9i, and differences in cognitive function domains, to analyze subgroups by the low-density lipoprotein cholesterol (LDL-C) achieved, and differences between alirocumab and evolocumab. Methods: This has a multicenter, quasi-experimental design carried out in 12 Spanish hospitals from May 2020 to February 2023. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA). Results: Among 158 patients followed for a median of 99 weeks, 52% were taking evolocumab and 48% alirocumab; the mean change from baseline in MoCA score at follow-up was + 0.28 [95% CI (? 0.17 to 0.73; p = 0.216)]. There were no significant differences in the secondary endpoints-the visuospatial/executive domain + 0.04 (p = 0.651), naming domain ? 0.01 (p = 0.671), attention/memory domain + 0.01 (p = 0.945); language domain ? 0.10 (p = 0.145), abstraction domain + 0.03 (p = 0.624), and orientation domain ? 0.05 (p = 0.224)-but for delayed recall memory the mean change was statistically significant (improvement) + 0.44 (p = 0.001). Neither were there any differences in the three stratified subgroups according to lowest attained LDL-C level-0-54 mg/dL, 55-69 mg/dL and ? 70 mg/dL; p = 0.454-or between alirocumab and evolocumab arms. Conclusion: We did not find effect of monoclonal antibody PCSK9i on neurocognitive function over 24 months of treatment, either in global MoCA score or different cognitive domains. An improvement in delayed recall memory was shown. The study showed no differences in the cognitive function between the prespecified subgroups, even among patients who achieved very low levels of LDL-C. There were no differences between alirocumab and evolocumab. Registration: ClinicalTtrials.gov Identifier number NCT04319081.
