BACKGROUNDPreliminary clinical trials of adamgammadex, a new cyclodextrin-based selective reversal agent, have demonstrated its efficacy in reversing neuromuscular block by rocuronium.METHODSThis multicentre, randomised, double-blind, positive-controlled, non-inferiority phase III clinical trial compared the efficacy and safety of adamgammadex and sugammadex. We randomised 310 subjects to receive adamgammadex (4 mg kg^-1) or sugammadex (2 mg kg^-1) at reappearance of the second twitch of the train-of-four (TOF), and standard safety data were collected.RESULTSFor the primary outcome, the proportion of patients with TOF ratio ≥0.9 within 5 min was 98.7% in the adamgammadex group vs 100% in the sugammadex group, with a point estimate and 95% confidence interval (CI) of 1.3% (-4.6%, +1.3%); the lower limit was greater than the non-inferiority margin of -10%. For the key secondary outcome, the median (inter quartile range) time from the start of administration of adamgammadex or sugammadex to recovery of TOF ratio to 0.9 was 2.25 (1.75, 2.75) min and 1.75 (1.50, 2.00) min, respectively. The difference was 0.50 (95% CI: 0.25, 0.50); the upper limit was lower than the non-inferiority margin of 5 min. In addition, there were no inferior results observed in secondary outcomes. Adamgammadex had a lower incidence of adverse drug reactions compared with sugammadex (anaphylactic reaction, recurarisation, decreased heart rate, and laryngospasm; P=0.047).CONCLUSIONSAdamgammadex was non-inferior to sugammadex with a possible lower incidence of adverse drug reactions compared with sugammadex. Adamgammadex may have a potential advantage in terms of its overall risk-benefit profile.CLINICAL TRIAL REGISTRATIONChinese Clinical Trial Registry, ChiCTR2000039525.

Muscle relaxant effect of new γ-cyclodextrin derivatives Aom0498-1 and Aom0498-3

Author: Qi, You-mao ; Qi, Ying-bei ; Ding, Ding ; Jie, Qing ; Yu, Bao-chun ; Zhang, Feng-min

To explore and screen the candidates of the selective muscle-relaxant antagonist against amino-steroid nondepolarizing muscle relaxants.Two 6-deoxy-6-thioether-acetylglycine-γ-cyclodextrin derivatives, Aom0498-1 and Aom0498-3 were synthesized using one-pot reaction.(1) γ-Cyclodextrin, Aom0498-1, Aom0498-3 and sugammadex 1.8, 3.6 and 5.4μmol·L^-1 were added to phrenic-nerve-diaphragm preparation of mice accordingly and the reversal rate of muscle contraction was recorded.(2) Guinea pigs were iv administered with γ-cyclodextrin, Aom0498-1, Aom0498-3 and sugammadex 2 mg·kg^-1 accordingly and recovery time of train-of-four ratio to 50% and 75% was recorded.(3) Rabbits were iv administered with γ-cyclodextrin, Aom0498-1, Aom0498-3 and sugammadex 6 mg·kg^-1 accordingly after paralysis and recovery time of the ear pinch reflex was recorded.(4) Aom0498-1 and Aom0498-3 2, 4 and 8 g·kg^-1 were iv given once time accordingly and clin. signs were monitored.(1) In mouse phrenic-nerve-diaphragm preparation model, the reversal rates of muscle contraction in Aom0498-1 1.8, 3.6 and 5.4μmol·L^-1 groups[(2.5±1.0)%, (6.9±2.6)% and(24.5±9.1)%] and those in Aom0498-3 groups[(17.4±1.7)%, (65.5±0.6)% and(100±8.9)%]were significantly higher than those in the corresponding groups of γ-cyclodextrin[(1.1±0.5)%, (2.6±0.7)%, and(10.3±6.1)%](P<0.05).The reversal rates of muscle contraction in Aom0498-3 1.8, 3.6 and 5.4μmol·L^-1 groups were significantly higher than those in sugammadex groups.The reversal rates of muscle contraction in Aom0498-1 1.8, 3.6 and 5.4μmol·L^-1 groups were significantly lower than those in sugammadex groups.(2) In the guinea pig model, the time for recovery of the train-of-four ratio to 50% and 75% in Aom0498-3 2 mg·kg^-1 group was significantly shorter than that in γ-cyclodextrin 2 mg·kg^-1 group(P<0.05), and was equivalent to that in sugammadex 2 mg·kg^-1 group.The recovery time of the train-of-four ratio to 50% in Aom0498-1 2 mg·kg^-1 group was significantly shorter than that in γ-cyclodextrin 2 mg·kg^-1 group, and the recovery time of the train-of-four ratio to 75% in Aom0498-1 2 mg·kg^-1 group was significantly longer than that in sugammadex 2 mg·kg^-1 group.(3)In the rabbit model, the recovery time in Aom0498-1 6 mg·kg^-1 group and in Aom0498-3 6 mg·kg^-1 group was significantly shorter than that in γ-cyclodextrin 6 mg·kg^-1 group(P<0.05).And the recovery time in Aom0498-3 6 mg·kg^-1 group was significantly shorter than that in sugammadex 6 mg·kg^-1 group.Single dose toxicity test showed that more mice in sugammadex 2, 4 and 8 g·kg^-1 groups with transient to mild side effects were observed when compared with those in the corresponding dose groups of Aom0498^-1 or Aom0498-3.Aom0498-1 and Ao0498-3 are of high reversal activities against sugammadex, indicating that the series of γ-cyclodextrin derivatives might be served as potential candidates of selective muscle-relaxant antagonists.

Efficiency and Safety of the Selective Relaxant Binding Agent Adamgammadex Sodium for Reversing Rocuronium-Induced Deep Neuromuscular Block: A Single-Center, Open-Label, Dose-Finding, and Phase IIa Study

Author: Chen, Sifan ; Zhao, Yanhua ; Huai, Xiaorong ; Qi, Youmiao ; Qing, Jie ; Yu, Weifeng ; Su, Diansan ; Yu, Zhangjie

Background: Rapid reversal of neuromuscular block after surgery and anesthesia is often necessary. Here, we reported the primary efficacy and safety data from a phase IIa study on adamgammadex sodium, a newly developed modified γ-cyclodextrin derivative.Methods: This was a phase IIa, single-center, randomized, open-label, and dose-finding study that enrolled 35 patients under general anesthesia who received the neuromuscular blocking agent rocuronium for induction and maintenance of neuromuscular blockade. The subjects were randomized to one of the five adamgammadex dose groups (2, 4, 6, 8, and 10 mg kg−1) and to the 4 mg kg−1 sugammadex group. Pharmacological efficacy was the recovery time from the start of adamgammadex or sugammadex administration to train-of-four (TOF) ratio ≥0.9, 0.8, and 0.7 among the different dose groups. Adverse events were recorded throughout the study.Results: The efficacy in reversing deep neuromuscular block was the same between 4 mg kg−1 sugammadex and adamgammadex. However, in the lowest dose groups of 2 and 4 mg kg−1 adamgammadex, adequate reversal could not be achieved in all subjects. The recovery time of TOF ratio to 0.9, 0.8, and 0.7 was shorter in the adamgammadex 10 mg kg−1 group than in the sugammadex 4 mg kg−1 group. The average values of the TOF ratio after 3 min of administration of adamgammadex 8 and 10 mg kg−1 and sugammadex 4 mg kg−1 were >90%. There were no serious adverse events after the use of adamgammadex, and no subjects had to be withdrawn from the trial.Conclusions: Adamgammadex enabled quick, predictable, and tolerable reversion of rocuronium-induced deep neuromuscular block in a dose-dependent manner. Adamgammadex doses of 6–10 mg kg−1 might be the recommended dose range for further exploration of efficacy. Clinical Trial Registration: This study was registered at chictr.org.cn, identifier: ChiCTR2000038391.
