A Study of Semagacestat for Alzheimer's Patients (Identity XT)
Open-Label Extension for Alzheimer's Disease Patients Who Complete One of Two Semagacestat Phase 3 Double-Blind Studies (H6L-MC-LFAN or H6L-MC-LFBC)
The primary objective of the original study was to assess the safety of semagacestat in Alzheimer's disease (AD) patients during 24 months of open-label treatment. Baseline for the efficacy measures is defined as the baseline for feeder studies LFAN (NCT00594568) and LFBC (NCT00762411). For all safety analyses (adverse events), baseline for patients will be week 0 of this study (LFBF).
Preliminary results from LFAN and LFBC showed semagacestat did not slow disease progression and was associated with worsening of clinical measures of cognition and the ability to perform activities of daily living. Study drug was stopped in all studies. Studies LFAN, LFBC and LFBF have been amended to continue collecting safety data, including cognitive scores, for at least seven months. The CT-Registry will reflect results of analyses from the original protocol in addition to those from the amended protocol. Very few participants from LFBC rolled over into LFBF (N = 9). Due to insufficient sample size, the data for LFBC participants who rolled into LFBF were not analyzed.

Change From Baseline in Alzheimer's Disease Assessment Scale - Cognitive Subscale (ADAS-Cog11) at Week 16 After Cessation of Study Drug
Ramy czasowe: Baseline (LFAN randomization), 16 weeks (LFBF) after cessation of study drug
|
The cognitive subscale of the ADAS (ADAS-Cog11) consists of 11 items assessing areas of function most typically impaired in Alzheimer's Disease (AD): orientation, verbal memory, language, and praxis.
The scale ranges from 0 to 70, with higher scores indicating greater disease severity.

|
EQ-5D (proxy version) measures mobility, self-care, usual activities, pain/discomfort, anxiety/depression; each has 3 severity levels (no, some, severe problems) coded to a 1-digit number (1-3).
Digits are combined into 5-digit number describing health state.
Numbers 1-3 are not added for total score.
Visual Analog Scale (VAS) assesses caregiver's impression of participant's overall health state; VAS scores range=0-100, with lower scores indicating greater disease severity.
LS Mean value was controlled for baseline value, age, investigator, and concomitant standard of care (SOC) medication.
