Condition(s) targeted: Anesthesia, General

Intervention: Rocuronium (Drug); Sugammadex (Drug); Neostigmine (Drug); Atropine (Drug)

Phase: Phase 3

Status: Completed

Sponsored by: Merck Sharp & Dohme Corp.


The current trial was designed to demonstrate faster recovery from a neuromuscular blockade (NMB) induced by rocuronium after reversal at 1-2 Post Tetanic Count (PTC) by 4. 0 mg. kg-1 sugammadex compared to 50 µg. kg-1 neostigmine at reappearance of second twitch (T2) in participants undergoing laparoscopic cholecystectomy or appendectomy under propofol anesthesia, to compare safety and to evaluate operating room and Post Anesthetic Care Unit (PACU) length of stay.

Clinical Details

Official title: A Multi-center, Randomized, Parallel-group, Comparative, Active-controlled, Safety-assessor Blinded Trial in Adult Subjects Comparing the Efficacy and Safety of Sugammadex (SCH 900616, ORG 25969) Administered at 1-2 PTC With Neostigmine Administered at Reappearance of T2 in Subjects Undergoing Laparoscopic Cholecystectomy or Appendectomy Under Propofol Anesthesia

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: Time From Start of Administration of Investigational Medicinal Product (IMP, Sugammadex or Neostigmine) to Recovery of the Fourth Twitch/First Twitch (T4/T1) Ratio to 0.9

Secondary outcome:

Time From Start of Administration of IMP to Recovery of the T4/T1 Ratio to 0.7

Time From Start of Administration of IMP to Recovery of the T4/T1 Ratio to 0.8

Number of Participants Who Experienced Pre-treatment Serious Adverse Events (SAEs) and Post-treatment SAEs

Number of Participants Who Experienced Pre-treatment Non-serious Adverse Events (AEs) and Post-treatment Non-serious AEs

Detailed description: In those surgical procedures where a neuromuscular block is desired for intubation and/or avoid unwanted muscular activity, anesthesiologists may use a more profound NMB until the end of surgery, e. g. in open abdominal procedures or during laparoscopic procedures in order to improve surgical conditions. Reversal with sugammadex at a dose of 4. 0 mg. kg-1 at 1-2 PTC after an intubation dose of 0. 6 mg. kg-1 or maintenance dosing rocuronium has been found to be both safe and efficacious in previous clinical trials but has never been investigated exclusively in participants undergoing laparoscopic cholecystectomy or appendectomy. With sugammadex profound muscle relaxation may now be provided right up to the end of the surgical procedure. This may lead to improved Patient Outcomes, such as improvement in the time from end of surgery to the discharge to the PACU. In this multi-center, randomized, parallel-group, active-controlled, safety-assessor blinded trial such benefits will be further investigated.
