NCT05696483

Brief Summary

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).

Outcome Measures

Primary Outcomes (4)

  • Incidence of Treatment-Emergent Adverse Events as Measured by NCI-CTCAE criteria

    Safety and tolerability of OLX-07010 will be assessed by documenting adverse events occurring after single dose administration (Parts 1, 3 and 4) and multiple dose administration (Part 2)

    After each dose of OLX-07010 through completion of dosing, up to 30 days

  • Incidence of Treatment-Emergent Adverse Events as Measured by Clinical Laboratory Measurements According to Established Clinical Normal Ranges

    Blood and Urine samples will be taken after administration of OLX-07010 and values will be compared to baseline and established normal ranges to determine how OLX-07010 administration impacts normal body function

    Change from baseline at 2-4 hours post-dose of OLX-07010

  • Incidence of Treatment-Emergent Adverse Events as Measured by ECG

    ECGs will be used to measure changes to the heart after administration of OLX-07010

    Change from baseline at 2, 4, and 8 hours and Days 2 and 4 post-dose of OLX-07010

  • Incidence of Treatment-Emergent Adverse Events as Measured by Neurological Examination

    Neurological assessments will be performed to investigate the potential effect of the study drug on mental status, gait (normal/abnormal), coordination/incoordination, tremor, muscle tone, stereotypy and biceps reflexes

    Change from baseline at Day 1, Day 4 (Parts 1 and 3) and Days 7 and 10 (Parts 2 and 4) post-dose of OLX-07010

Secondary Outcomes (5)

  • Maximum drug concentration in plasma (Cmax) of OLX-07010 after single ascending doses

    Blood collection on Day 1, 2, 3, and 4. On Day 1 (pre-dose 0 hour, post-dose at 15 minutes, 30 minutes, 1, 1.5, 2, 3, 4, 5, 7, 9, and 12 hours), Day 2 (24 hours post-dose), Day 3 (48 hours post-dose) and Day 4 (72 hours post-dose).

  • Maximum drug concentration in plasma (Cmax) of OLX-07010 after multiple ascending doses

    Day 1and Day 7 (pre-dose 0 hour, and post-dose at 15 minutes, 30 minutes, 1, 1.5, 2, 3, 4, 5, 7, 9, 12 hours), Days 2 (24 hours post-dose) to Day 6 (pre-dose 0 hours), Day (24 hours post-dose), Day 9 (48 hours post-dose), and Day 10 (72 hours post-dose).

  • Area under the concentration-time curve in plasma (AUC) of OLX-07010 after single ascending doses.

    Blood collection on Day 1, 2, 3, and 4. On Day 1 (pre dose 0 hour, post-dose at 15 minutes, 30 minutes, 1, 1.5, 2, 3, 4, 5, 7, 9, and 12 hours), Day 2 (24 hours post-dose), Day 3 (48 hours post-dose) and Day 4 (72 hours post-dose).

  • Area under the concentration-time curve in plasma (AUC) of OLX-07010 after multiple ascending doses.

    Day 1and Day 7 (pre-dose 0 hour, and post-dose at 15 minutes, 30 minutes, 1, 1.5, 2, 3, 4, 5, 7, 9, 12 hours), Days 2 (24 hours post-dose) to Day 6 (pre-dose 0 hours), Day (24 hours post-dose), Day 9 (48 hours post-dose), and Day 10 (72 hours post-dose).

  • Renal clearance and percent drug excreted in Urine after single and multiple ascending doses of OLX-07010.

    Part 1:Day 1 at 0 hour (pre-dose), 0-4; 4-8; 8-12; and 12-24 hours post-dose. Part 2: Day 1 and Day 7 at 0 hour (pre-dose), 0-4 hours; 4-8 hours; 8-12 hours; 12-24 hours.
