Detailed Description
Synopsis Trial Number 12.4.104 Trial Title First administration to man of Org 25435 a new intravenous anesthetic Trial Center Phase 1 Clinical Trials Unit Limited, 119 Looseleigh Lane, Derriford, Plymouth PL6 5HH Publication Studied Period The first subject was screened on 04/01/2000 and the final subject completed the follow up on 24/03/2000.
Phase of Development Phase I (First into Man) Objectives To assess the safety, tolerability and efficacy of Org 25435 as an intravenous anesthetic and to obtain preliminary pharmacodynamic and pharmacokinetic details of Org 25435.
Methodology Sequential rising dose study of an intravenous anesthetic in young healthy males, at up to eight dose levels.
Number of Subjects 19 healthy male volunteers were included into the dose escalation part of the study and an additional 7 volunteers participated in the Target Controlled Infusion (TCI) part of the study.

Dose Escalation phase:
Each study treatment consisted of an intravenous infusion of Org 25435, given by Infusion pump over exactly 1 minute.
Target Controlled Infusion phase:
Each study treatment consisted of an intravenous infusion of Org25435 given by a computer-controlled infusion over 30 minutes.
Criteria for Evaluation Tolerability, adverse events, EEG effects, cardiovascular effects, electrocardiogram (ECG), excitatory phenomena, respiratory effects, laboratory safety blood analyses, pharmacodynamic and pharmacokinetic measurements. Efficacy Induction phenomena; time of cessation of speech, eye closure, loss of eyelash reflex, eyes open on command, limb movement on command and syringe drop. Other Induction phenomena; pain on injection, sign of histamine release, excitatory phenomena, respiratory depression, apnea. Recovery phenomena; nausea / vomiting, delirium, shivering, disturbed psychomotor function, eye opening on command, spontaneous respiration, adequate respiration, move limbs on command, increased saliva production.
Statistical Methods Formal statistical methods are not appropriate in this small pilot investigative study where group sizes comprise 5 or less subjects. All data collected is presented and summarized according to investigation type (Dose Escalation or TCI).
