ABSTRACT P2D Bioscience is developing a first-in-class treatment for Alzheimer’s disease (AD). Our drug is an orally-effective combination that targets both innate immunity and the dopamine transport (DAT) inhibitor. Recent studies suggest that TNFα and DAT inhibitors are orally effective treatments for AD in preclinical AD transgenic mouse models. The proposed studies will determine if our compound is an effective treatment for AD using a three transgenic animal models of AD. The rationale is rigorously evaluation for our lead compound across different models of AD pathology in this limited direct-to-phase 2 SBIR application. The proposed specific aims will determine if chronic oral treatment significantly improves AD symptoms and AD /FTD pathophysiology in these animal models. Aim 1 : Determine the brain and plasma PK profile of our dual acting lead compound to aid in developing a PKPD correlation. Aim 2: Determine the efficacy of chronic daily oral treatment of our dual acting lead compound at improving cognitive/behavioral function in three transgenic models of dementia and their AD-associated pathology
