Sugammadex Hypersensitivity Study (Study P06042)

This trial was conducted to study the potential for hypersensitivity symptoms at the time of initial exposure to sugammadex and upon repeat exposure, since it was unknown whether the frequency or severity of hypersensitivity symptoms may worsen at repeat exposure over a prolonged period.

In total 450 participants (all healthy subjects) were to be randomized to receive one of three study treatments: three repeated doses of either sugammadex 4 mg/kg, sugammadex 16 mg/kg, or placebo. Participants were to receive one dose of study treatment on Day 8, Day 36, and Day 78 of the study in order to determine the safety of each treatment dose.

About this study

All subjects were to be admitted to the study center the day before each scheduled dose and were to leave the unit the morning of the day after each dose. In cases of suspected hypersensitivity symptoms, healthy subjects were to remain confined to the study center until all signs and symptoms regressed, the subject was stable, and the investigator considered it safe for the subject to leave the study center. Four sites participated in this trial.

Primary outcomes

  1. The Percentage of Participants With Adjudicated Hypersensitivity Signs/Symptoms, for Each Sugammadex Dose Group and Placebo.

    Time frame: Day 8, Day 36, and Day 78 of the study

    Hypersensitivity signs/symptoms were systematically collected for each subject by the investigator. Suspected cases of hypersensitivity signs/symptoms were sent to the independent Adjudication Committee (comprised of anesthesiologists & allergists/immunologists) for blinded review and determination of adjudicated hypersensitivity &/or anaphylaxis based on expert evaluation of all clinical data from the healthy subject.

    The percentages of subjects who had adjudicated hypersensitivity at any dose (dose 1/Day 8, dose 2/Day 36, or dose 3/Day 78) were compared between the 3 treatment groups.

Secondary outcomes

  1. The Percentage of Participants With Adjudicated Anaphylaxis According to the Definition by Sampson et al., for Each Sugammadex Dose Group and Placebo.

    Time frame: Day 8, Day 36, and Day 78 of the study

    The Adjudication Committee evaluated each case to determine whether the subject's hypersensitivity sign/symptoms fulfilled the definition of anaphylaxis according to the criteria defined by the Symposium on the Definition and Management of Anaphylaxis as described by Sampson et al. (J Allergy Clin Immunol 2006; 117:391-7).

    The percentages of subjects who had adjudicated anaphylaxis according to the Sampson Criteria at any dose (dose 1 [~Day 8], dose 2 [~Day 36], or dose 3 [Day ~78]) were compared between the 3 treatment groups.

  2. The Percentage of Participants With Each of the 3 Levels of Diagnostic Certainty of Adjudicated Anaphylaxis According to the Definition by Rüggeberg et al., for Each Sugammadex Dose Group and Placebo.

    Time frame: Day 8, Day 36, and Day 78 of the study

    The Adjudication Committee evaluated each case to determine anaphylaxis according to the criteria put forth by the guidelines of the Brighton Collaboration Anaphylaxis Working Group as described by Rüggeberg et al. (Vaccine 2007; 25:5675-5684).

    Level 1 represents the highest level of certainty of anaphylaxis and level 3 the lowest level of certainty.

    The percentages of subjects who had adjudicated anaphylaxis according to the Rüggeberg Criteria at any dose (dose 1 [~Day 8], dose 2 [~Day 36], or dose 3 [Day ~78]) were compared between the 3 treatment groups.

  3. The Percentage of Participants With Adjudicated Hypersensitivity Signs/Symptoms After Each Randomized Dose of Study Treatment, for Each Sugammadex Dose Group and Placebo.

    Time frame: Day 8, Day 36, and Day 78 of the study

    Hypersensitivity signs/symptoms were systematically collected for each subject by the investigator. Suspected cases of hypersensitivity signs/symptoms were sent to the independent Adjudication Committee (comprised of anesthesiologists & allergists/immunologists) for blinded review & determination of adjudicated hypersensitivity &/or anaphylaxis based on expert evaluation of all clinical data from the healthy subject.

    The percentages of subjects who had adjudicated hypersensitivity (dose 1/Day 8, dose 2/Day 36, or dose 3/Day 78) are presented for each of the 3 treatment arms for each dose.

Other outcomes

  1. Percentage of Participants With an Adverse Event Suggestive of a Dose-dependent Trend That Also Exceeds a Frequency Threshold Above 5% in Any Treatment Arm (Including Both Serious and Non-serious Adverse Events).

    Time frame: From first randomized dose (Day 8) up to 30 days after day of last randomized dose of study medication.

    All adverse events from the study were reviewed for potential safety signals. The reported incidences suggestive of a dose-dependent trend and with a frequency threshold above 5% (including both serious and non-serious adverse events) are presented.
