A Phase 4 Randomized, Active-Comparator Controlled Trial to Study the Efficacy and Safety of Sugammadex (MK-8616) for the Reversal of Neuromuscular Blockade Induced by Either Rocuronium Bromide or Vecuronium Bromide in Morbidly Obese Subjects
In Brief
A Phase 4 clinical trial evaluating Sugammadex 2 mg/kg ABW, Sugammadex 2 mg/kg IBW, and 4 other interventions for Neuromuscular Blockade. Completed, enrolled 207 participants across 24 sites in 5 countries.
Detailed Summary
The purpose of this trial is to evaluate the safety and efficacy of Sugammadex when administered according to actual body weight (ABW) as compared to ideal body weight (IBW) for the reversal of both moderate and deep neuromuscular blockade (NMB) induced by either Rocuronium or Vecuronium in morbidly obese participants. The primary hypothesis of this investigation is that, compared to obese participants dosed based on IBW, obese participants receiving Sugammadex according to ABW will demonstrate a faster time to recovery to a Train Of Four (TOF) ratio of ≥0.9 (i.e. faster NMB reversal), pooled across NMB depth and type of neuromuscular blocking agent (NMBA; Rocuronium or Vecuronium) administered.

Timeline
Interventions
Following administration of NMBA (Rocuronium or Vecuronium) to achieve moderate NMB, participants received a single i.v. bolus of Sugammadex (2 mg/kg by ABW) for reversal of moderate NMB. Moderate NMB is defined as the reappearance of a second twitch (T2) in response to TOF stimulations.
Following administration of NMBA (Rocuronium or Vecuronium) to achieve moderate NMB, participants received a single i.v. bolus of Sugammadex (2 mg/kg by IBW) for reversal of moderate NMB. Moderate NMB is defined as the reappearance of T2 in response to TOF stimulations.
Following administration of NMBA (Rocuronium or Vecuronium) to achieve deep NMB, participants received a single i.v. bolus of Sugammadex (4 mg/kg by ABW) for reversal of deep NMB. Deep NMB is defined as no response to TOF stimulations (TOF=0) and a detection target of 1-2 post-tetanic counts (PTCs).
Following administration of NMBA (Rocuronium or Vecuronium) to achieve deep NMB, participants will receive a single i.v. bolus of Sugammadex (4 mg/kg by IBW) for reversal of deep NMB. Deep NMB is defined as no response to TOF stimulations (TOF=0) and a detection target of 1-2 post-tetanic counts (PTCs).
Following administration of NMBA (Rocuronium or Vecuronium) to achieve moderate NMB, participants received a single i.v. bolus of Neostigmine (50 µg/kg; 5 mg maximum) and Glycopyrrolate (10 µg/kg; 1 mg maximum), dosed according to participant ABW for reversal of moderate NMB. Moderate NMB is defined as the reappearance of T2 in response to TOF stimulations.
To achieve NMB, participants received steroidal NMBA Rocuronium Bromide or Vecuronium Bromide administered via i.v. infusion and dosed according to participant ABW. NMBAs were concomitant medications used per label as adjunct to general anesthesia.
