This FIH Phase 1 randomized, double-blind, four-part study will be conducted to evaluate the safety, tolerability, and PK of the tau self-association inhibitor, OLX-07010 in single ascending doses, multiple ascending doses in healthy adult participants, and as a single dose in healthy elderly participants. There is an option for an additional part to evaluate the effects of food (fed and fasted) on OLX-07010 in healthy adult participants. This study will be divided into 4 parts: Part 1-Randomized Double-Blind Single Ascending Dose in Healthy Adult Participants; Part 2-Randomized Double-Blind Multiple Ascending Dose in Healthy Adults Participants; Part 3-Randomized Double-Blind Single Dose in Healthy Elderly Participants; and Part 4 (Optional)-Food Effect (Single Cohort, 2 Sequence, 2 Period Crossover Fed and Fasted) in Healthy Adult Participants.
This First-in-human (FIH) study will evaluate the safety, tolerability, and pharmacokinetics of the tau self-association inhibitor, OLX-07010 in single ascending doses (SAD) and multiple ascending doses (MAD) in healthy adults (18-50 of age inclusive), and single dose in healthy elderly (51-75 of age inclusive). The effects of dosing with or without food in healthy adults will also be studied (optional).
