Introduction
The API AutosomalDominant AD (ADAD) Colombia Trial is a placebo‐controlled clinical trial of crenezumab in 252 cognitively unimpaired 30 to 60‐year‐old
Presenilin 1 (PSEN1) E280A
kindred members, including mutation carriers randomized to active treatment or placebo and non‐carriers who receive placebo.
Methods
Of the 252 enrolled, we present data on a total of 242 mutation carriers and non‐carriers matched by age range, excluding data on 10 participants to protect participant confidentiality, genetic status, and trial integrity.
Results
We summarize demographic, clinical, cognitive, and behavioral data from 167 mutation carriers and 75 non‐carriers, 30 to 53 years of age. Carriers were significantly younger than non‐carriers ((mean age ± SD) 37 ± 5 vs 42 ± 6), had significantly lower Mini Mental Status Exam (MMSE) scores (28.8 ± 1.4 vs 29.2 ± 1.0), and had consistently lower memory scores.
Discussion
Although
PSEN1 E280A
mutation carriers in the Trial are cognitively unimpaired, they have slightly lower MMSE and memory scores than non‐carriers. Their demographic characteristics are representative of the local population.
