Condition(s) targeted: Anesthesia, General

Intervention: sugammadex (Org 25969) (Drug); Placebo (Drug)

Phase: Phase 2

Status: Completed

Sponsored by: Merck Sharp & Dohme Corp.

Summary

The objective of the trial was to explore the dose-response relation of Org 25969 given as a reversal agent at 3 and 15 minutes following administration of 1. 0 and 1. 2 mg/kg of Esmeron« (rocuronium) in subjects of ASA 1 to 3, and to evaluate the safety of single doses of Org 25969 administered to subjects of ASA 1 to 3.

Clinical Details

Official title: A Multi-Center, Randomized, Safety Assessor-Blinded, Placebo- Controlled, Phase II, Parallel Dose-Finding Trial in Subjects of ASA 1-3 to Assess the Efficacy and Safety of 5 Doses of Sugammadex Administered at 3 and 15 Minutes After Administration of 1.0 and 1.2 mg/kg Rocuronium Bromide

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Time from start of administration of Org 25969 / placebo to recovery of the T4/T1 ratio to 0.9

Secondary outcome: Time from start of administration of Org 25969 / placebo to recovery of the T4/T1 ratio to 0.7; Time from start of administration of Org 25969 / placebo to recovery of the T4/T1 ratio to 0.8.

Detailed description: In the US the highest dose recommended in the package insert of Zemuron® (i. e. the trade name for Esmeron® in the US) is 1. 2 mg/kg whereas in Europe it is 1. 0 mg/kg. For both doses, dose recommendations for reversal with Org 25969 were to be found. Hence, the present trial was set up to explore the dose-response relation of Org 25969 given as a reversal agent at 3 and 15 minutes following administration of 1. 0 and 1. 2 mg/kg of Esmeron® in subjects of ASA 1 to 3. The sub-investigator who performed any subjective safety assessments after anesthesia was to be remained blinded.
