Optimal follow-up schedule for patients taking PCSK9 monoclonal antibodies in a health system: Analysis of specialty pharmacy clinical interventions.

Purpose: The objective of this study was to determine if and when it is clinically appropriate to consider a reduction in the frequency of health-system specialty pharmacy (HSSP) clinical pharmacist assessments for patients taking a proprotein convertase subtilisin/kexin type 9 (PCSK9) monoclonal antibody (mAb) after they are deemed clinically stable on therapy.

Methods: A single-center, retrospective, observational study of adult patients on PCSK9 mAb therapy enrolled in the University of Rochester Specialty Pharmacy Cardiology Patient Management Program was performed between October 24, 2016, and April 30, 2022. The primary outcome was the number of clinical pharmacist interventions per interval within the baseline 12 months compared to 12-month intervals for up to 72 months after initiation of PCSK9 mAb therapy.
