Description of a European memory clinic cohort undergoing amyloid-PET: the AMYPAD diagnostic and patient management study

Data de publicació electrónica: 17-06-2022Introduction: AMYPAD Diagnostic and Patient Management Study (DPMS) aims to investigate the clinical utility and cost-effectiveness of amyloid-PET in Europe. Here we present participants' baseline features and discuss the representativeness of the cohort. Methods: participants with subjective cognitive decline plus (SCD+), mild cognitive impairment (MCI), or dementia were recruited in eight European memory clinics from April 16, 2018, to October 30, 2020, and randomized into three arms: ARM1, early amyloid-PET; ARM2, late amyloid-PET; and ARM3, free-choice. Results: A total of 840 participants (244 SCD+, 341 MCI, and 255 dementia) were enrolled. Sociodemographic/clinical features did not differ significantly among recruiting memory clinics or with previously reported cohorts. The randomization assigned 35% of participants to ARM1, 32% to ARM2, and 33% to ARM3; cognitive stages were distributed equally across the arms. Discussion: the features of AMYPAD-DPMS participants are as expected for a memory clinic population. This ensures the generalizability of future study results.This communication reflects the views of the authors and neither the Innovative Medicines Initiative (IMI) nor the European Union and the European Federation of Pharmaceutical Industries and Associations (EFPIA) are liable for any use that may be made of the information contained herein.
