Treatment emergent anti-drug antibodies were found in six (12%)
patients in the alirocumab arm and were not observed in patients in
the ezetimibe arm. Five of these patientswere classified as having a persistent
response with a positive anti-drug antibody status recorded at
follow-up visit. For all anti-drug antibody-positive patients, titers were
low and no neutralizing anti-drug antibody which may impact
alirocumab pharmacokinetics, LDL-C effects, or safety was detected
