Safety of Sugammadex for the Reversal of Neuromuscular Blockade in American Society of Anesthesiologists (ASA) Class 3 or 4 Participants (MK-8616-145)
Safety of Sugammadex for the Reversal of Neuromuscular Blockade in American Society of Anesthesiologists (ASA) Class 3 or 4 Participants (MK-8616-145)
The purpose of this trial is to evaluate the safety of sugammadex for the reversal of
 neuromuscular blockade (NMB) induced by neuromuscular blockade agents (NMBA) rocuronium or
 vecuronium in adult American Society of Anesthesiologists (ASA) Physical Status Class 3 and 4
 participants. The primary objectives of the study are to characterize the incidence of
 treatment emergent sinus bradycardia, treatment emergent sinus tachycardia, or other
 treatment emergent cardiac arrhythmias after administration of sugammadex and to evaluate the
 general safety of sugammadex in a population of ASA Class 3 and 4 participants in a surgical
 setting.
Inclusion Criteria:

 -  Has a body mass index (BMI) < 40 kg/m2.

 -  Is categorized as ASA Physical Status Class 3 or 4, as determined by the Investigator.

 -  Has a planned surgical procedure that requires NMB with either rocuronium or
 vecuronium.

 -  Has a planned surgical procedure (e.g., gastrointestinal, urologic, or laparoscopic)
 that in the opinion of the investigator does not preclude maintenance of moderate or
 deep depth of NMB throughout the case.

 -  If female who is not of reproductive potential, is one of the following: (1)
 postmenopausal; (2) has had a hysterectomy and/or bilateral oophorectomy, bilateral
 salpingectomy, or bilateral tubal ligation/occlusion at least 6 weeks prior to
 screening; (3) has a congenital or acquired condition that prevents childbearing; or
 (4) is undergoing surgical sterilization (e.g., hysterectomy or tubal ligation) as the
 planned surgical procedure associated with participation in this study.

 -  If female who is sexually active and of child-bearing potential, agrees to use a
 medically accepted method of contraception through seven days after receiving
 protocol-specified medication. Abstinence (relative to heterosexual activity) can be
 used as the sole method of contraception if it is consistently employed as the
 subject's preferred and usual lifestyle and if considered acceptable by local
 regulatory agencies and Ethics Review Committees/Institutional Review Boards.

 -  Is able to provide (or the participant's legally authorized representative, in
 accordance with local requirements), written informed consent for the trial. The
 participant or legally authorized representative may also provide consent for Future
 Biomedical Research.

 Exclusion Criteria:

 -  Has a pacemaker or automatic implantable cardioverter-defibrillator that precludes the
 assessment of bradycardia or arrhythmias.

 -  Has a medical condition or surgical procedure that precludes reversal of neuromuscular
 block at the end of surgery.

 -  Has a neuromuscular disorder(s) that may affect neuromuscular block and/or trial
 assessments.

 -  Is dialysis-dependent or has severe renal insufficiency, defined as estimated
 creatinine clearance of <30 mL/min.

 -  Has or is suspected of having a personal history or family history (parents,
 grandparents, or siblings) of malignant hyperthermia.

 -  Has or is suspected of having an allergy (e.g., hypersensitivity and/or anaphylactic
 reaction) to study treatments or its/their excipients, to opioids/opiates, muscle
 relaxants or their excipients, or other medication(s) used during general anesthesia.

 -  Has received or is planned to receive toremifene within 24 hours before or within 24
 hours after study medication administration.

 -  Has any condition that would contraindicate the administration of study medication.

 -  Is pregnant, is attempting to become pregnant, or is lactating.

 -  Is currently participating in or has participated in an interventional clinical trial
 (including any other current or ongoing trial with a sugammadex treatment arm) with an
 investigational compound or device within 30 days of signing the informed consent form
 of this current trial.
