Brief Summary:
This Phase 1 study is a single ascending dose (SAD) and multiple ascending dose (MAD), placebo-controlled study to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of intravenous ACU193 when administered to participants diagnosed with Mild Cognitive Impairment (MCI) or Mild Dementia due to Alzheimer's disease (AD).
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Alzheimer Disease | Drug: ACU193 Drug: Placebo | Phase 1 |
| Study Type : | Interventional (Clinical Trial) |
| Estimated Enrollment : | 62 participants |
| Allocation: | Randomized |
| Intervention Model: | Parallel Assignment |
| Intervention Model Description: | Study ACU-001 is a placebo-controlled study to investigate the safety, tolerability, pharmacokinetics, and pharmacodynamics of single and multiple escalating doses of intravenous ACU193. A two-part single-ascending dose (SAD)/multiple-ascending dose (MAD) study design will be conducted in a population of individuals with early AD (MCI or mild dementia due to AD). |

- Individual (or the participant's Legally Authorized Representative [LAR]) is able to give informed consent.
- Are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.
-
Must meet all of the following clinical criteria for MCI due to AD or mild AD at Screening:
- Participant meets NIA-Alzheimer's Association (NIA-AA) criteria for MCI due to AD or probable AD.
- A global Clinical Dementia Rating (CDR) of 0.5 or 1.0.
- A Mini-Mental State Examination (MMSE) score between 18 and 30 (inclusive).
