简要总结
The study will investigate the effects of oral ALZ-801, in subjects with Early AD who have the APOE4/4 or APOE3/4 genotype, on the biomarkers of core AD pathology. The objectives of this study include determining the efficacy and safety/tolerability of ALZ-801. In addition, the study will evaluate the extended PK profile over 8 hours in 16 subjects after 65 weeks of treatment.
详细描述
The LTE year 1 & 2 study will investigate the effects of oral ALZ-801, in subjects with Early AD who have the APOE4/4 or APOE3/4 genotype, on the biomarkers of core AD pathology. The objectives of LTE study are to continue longitudinal assessment of the efficacy and safety/tolerability of ALZ-801 over a total period of 4 years (2-year Core study plus 2 years of LTE).
Core study: ALZ-801 265 mg twice daily (BID) in the Core Study, Weeks 0-104
LTE year 1: ALZ-801 265 mg BID in the Core Study and the Long-Term Extension (LTE, Weeks 104-208)
LTE year 2: ALZ-801 265mg BID in the Core Study and LTE Year 1 (Weeks 104-156), and LTE Year 2 (Weeks 156-208)
