Change From Baseline in Cogstate Battery Test - Overall Composite Score at Weeks 24, 68 and 104 |
Cogstate battery test (cognitive testing system) consisted of detection test (DET), identification test (IDN), one card learning test (OCL) and Groton maze learning test (GML) to assess processing speed, attention, visual learning and executive functioning, respectively. For each test, Z-scores were computed based on participant's age at Baseline and Weeks 24, 68 and 104. Composite score: calculated as mean of Z-scores equally weighted, provided that at least 3 of 4 tests were available and if all of these domains were covered as: attention, through either DET or IDN, visual learning, through OCL and executive function, through GML. There is not minimum/maximum since values were reported as z-score but z-score of 0 means result equals to mean with negative numbers indicating values lower than mean and positive values higher. Positive change in z-score = an improvement in cognition, i.e., a better outcome; and negative change in z-score = worsening in cognition, i.e., a worse outcome. |

Tanner stage defines physical measurements of development in children and adolescent based on external primary and secondary sex characteristics. Participants were evaluated for pubic hair distribution, breast development (only females) and genital development (only males) and classified in 3 categories as: Prepubescent (defined as a person just before start of the development of adult sexual characteristics), Pubescent (defined as a person at or approaching the age of puberty), Postpubescent (sexually mature or a person who has completed puberty). |

Anti-drug (alirocumab) antibodies samples were analyzed using a validated non-quantitative, titer-based bridging immunoassay. Number of participants with positive ADA during 24-week treatment period is reported. Treatment-emergent positive ADA response was defined as 1) participants with no ADA positive response at baseline but with any positive response in the post-baseline period or 2) participants with a positive ADA response at baseline and at least a 4- fold increase in titer in the post-baseline period. A persistent positive response was defined as a TE ADA positive response detected in at least 2 consecutive post-baseline samples separated by at least a 12-week period. Persistent positive response was only analyzed for participants with positive TE ADA response. |
