Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - SPG302
Treatment: Drugs - Placebo

Active comparator: Part A: Active SPG302 to be administered to adult participants with AD - Cohort 1: 12 participants with Alzheimer's Disease will be randomized in a 2:1 ratio to receive SPG302 or placebo. Study intervention will be 300 mg orally once daily for 28 days (cycle 1). All participants will receive open-label SPG302 for cycles 2-7. This arm may be expanded to cohort 2: 12 additional participants pending review of data, for additional dose exploration.

Placebo comparator: Part A: Placebo comparator to be administered to adult participants with AD - Cohort 1: 12 participants with Alzheimer's Disease will be randomized in a 2:1 ratio to receive SPG302 or placebo. Study intervention will be placebo capsule orally daily for 28 days (cycle 1). All participants will receive open-label SPG302 for cycles 2-7. This arm may be expanded to 12 additional participants as cohort 2 pending review of data, for additional dose exploration.

Experimental: Part B: Expansion Cohort - Dose to be used and size of dosing cohort to be determined by Data Safety and Monitoring Committee following completion of Part A.
