AIBL Highlights A PET has defined the course of AD yrs Detectable AD Mean Villemagne VL, et al. Lancet Neurology diagnostic, prognostic and therapeutic implications Aβ+ ε4- Aβ+ ε4+ BDNF Val/Va l Aβ+ ε4+ BDNF Met Genes and lifestyle influences on decline Lim YY et al. Molecular Psychiatry 2014 Continually under refinement. GWAS and SNP analyses underway.
4.5 year imaging data release PiB Baseline (288), 3 years (173), 4.5 yrs (141) Plus 230 more imaged with flutemetamol, florbetapir or PiB at 3 or 4.5 yrs Plus 245 new recruits (150 flute, 95 FBP) - Data and Samples - Access Data (A status known in 371 subjects with 4.5 yrs of follow-up)
Implemented the Centiloid transformation for 11 C-PiB and 18 F-NAV4694 with 18 F-Florbetapir to follow. GAAIN PiB SUVR GAAIN Centiloid
THK5117 (now replaced with THK5351) Beta-amyloidTau Tau Imaging AV1451
THK5317 tau imaging in Alzheimer’s disease 18 F-THK F-FLUTEMETAMOL Braak & Braak Stage C Braak & Braak Stage V-VI AA tau MilxView
18 F-THK5351 PET Normal 71 yr old. MMSE 29. Mild tau tracer retention in anteromedial temporal lobe but much less than in AD Negative A PET
69 yrs old female with MCI MMSE 24 CDR 0.5 A PET +ve Tau PET – right top and bottom - 18F-THK5351
64 yrs with “AD” but A PET Negative Memory -3 SD Other domains OK MMSE 28 CDR 1 THK5351 shows high medial temporal tau
Screening for AD Drug Trials FDG and amyloid PET if: - MCI/mild AD (CVLT <-1 SD) - trial suitable - willing to go into a drug trial Reports go to treating doctor. That doctor chooses trial or asks us to do this. All scanned patients enrol in AIBL - more MCI/AD baseline data - good source of A –ve MCI and AD mimics - (20%) To date 9/43 (20%) had negative A PET
A4 Trial in Australia Over 1000 website registrations of interest A PET screening commenced early screening PET to date Aiming for 100 on study

Future Directions for AIBL Further refine prognostic value and comparative effectiveness of imaging and blood biomarkers Examine genetic and environmental influences on rate of decline in A +ve HC Serial tau imaging Create new pools of A +ve for early intervention trials Use AIBL infrastructure to support more A4 and DIAN therapy type trials
