* Evidence of early AD, as defined by all of the following:

1. Memory complaint by subject or study partner that is verified by a study partner;
2. Objective memory impairment for age, documented by scoring below the education adjusted cutoff of the Logical Memory II subscale (Delayed Paragraph Recall) from the Wechsler Memory Scale Third Edition (the maximum score is 25):

Summary
Brief summary
This is a global Phase III, randomized, double-blinded, placebo-controlled study for subjects with evidence of early AD. The protocol is designed to determine whether ALZT-OP1 combination treatment (ALZT-OP1a + ALZT-OP1b) will slow down, arrests, or reverse cognitive and functional decline, in subjects with evidence of early stage Alzheimer's disease (AD).
