Pilot Study of ORG 25935 Modulation of Ketamine-induced Behavioral and Cognitive Effects in Healthy Male Subjects

Brief Summary

Org 25935 is a new putative antipsychotic agent developed by N.V. Organon.The primary objective of this study is to investigate the effect of Org 25935 on ketamine-induced impairments in immediate recall.

Intervention / Treatment

  • Ketamine and Org 25935 (DRUG)
    Oral administration of Org 25935 16 mg and intravenous administration of ketamine (0.23 mg/kg bolus over 1 minute, followed by 0.58 mg/kg/hour x 30 minutes, followed by 0.29 mg/kg/hour x 69 minutes)
  • Placebo and Ketamine (DRUG)
    Oral administration of placebo and intravenous administration of ketamine (0.23 mg/kg bolus over 1 minute, followed by 0.58 mg/kg/hour x 30 minutes, followed by 0.29 mg/kg/hour x 69 minutes)
