Drug Development/Existing Targets: Phase 2 trials (Milestone 5.B)
In Progress
Timeline Start - End
2015 - 2024Research Implementation Area
Drug Development - Existing TargetsInitiate Phase 2 (proof of concept) drug trials for agents against 3-6 currently known therapeutic targets. Of these at least 2 will be for targets involved in at-risk asymptomatic individuals (e.g. FAD or ApoE4 carriers, Down syndrome, amyloid positive, type II diabetes, etc.) These trials will be designed to provide or confirm proof of mechanism and/or evidence of target engagement for the therapeutic agent being tested.
Success Criteria
- Completion of 3-6 Phase 2 drug trials for agents against currently known targets, providing conclusive evidence of therapeutic mechanism/target engagement.
Summary of Key Accomplishments
Ten Phase 2 trials testing eight new drug candidates for existing targets (amyloid/tau/acetylcholinesterase) have been supported. Of these, seven trials are in asymptomatic, at-risk individuals and three trials are in individuals symptomatic for late-onset AD. Of the ten Phase 2 trials:
- one trial testing two drugs (DIAN-TU) was successfully completed and advanced into Phase 3 testing
- seven trials are ongoing
- one trial (API-ApoE4) was terminated early due to lack of efficacy and unanticipated toxicity
- one trial is expected to be initiated in 2022
The key accomplishments summary is current as of July 2022.
