Effects of TS-134 on Ketamine-induced BOLD Signals in Healthy Subjects

Brief Summary

The purpose of this study is to evaluate the effects of TS-134 on ketamine-induced BOLD signals in ROIs in resting fMRI in healthy adult subjects.

Intervention / Treatment

  • TS-134 (DRUG)
    Multiple dose titrations from 10 mg to 60 mg once daily for 6 days
  • Placebo (DRUG)
    Multiple doses of placebo once daily for 6 days
  • Ketamine (OTHER)
    0.23 mg/kg bolus over one minute on Screening (baseline) and Day 6

    Primary Outcomes
    • Changes in ketamine-induced BOLD fMRI signals in pre-specified ROIs (anterior cingulate cortex (ACC) and anterior insula) following administrations of TS-134

    Secondary Outcomes
    • Changes in ketamine-induced BOLD fMRI signals in whole brain following administrations of TS-134

    • Changes in BPRS scores following administrations of TS-134

    • Changes in CADSS scores following administrations of TS-134
