sugammadex 500 mg/5mL Injection, Solution — NDC 16729-727-03 (Billing 16729-0727-03)

5 WARNINGS AND PRECAUTIONS Anaphylaxis : Be prepared for hypersensitivity reactions (including anaphylactic reactions) and take necessary precautions.( 5.1 ) Marked Bradycardia : Cases of marked bradycardia, some of which have resulted in cardiac arrest, have been observed within minutes after administration. Monitor for hemodynamic changes and administer anticholinergic agents such as atropine if clinically significant bradycardia is observed. ( 5.2 ) Respiratory Function Monitoring : Ventilatory support is mandatory until adequate spontaneous respiration is restored and the ability to maintain a patent airway is assured.

Provide adequate ventilation if neuromuscular blockade persists after sugammadex or recurs following extubation. ( 5.3 , 5.4 ) Waiting Times for Re-Administration of Neuromuscular Blocking Agents : If re-administration of a neuromuscular blocking agent is required after reversal with sugammadex, waiting times should be based on the dose of sugammadex, and the renal function of the patient. Consider use of a nonsteroidal neuromuscular blocking agent.

5.1Anaphylaxis and Hypersensitivity Clinicians should be prepared for the possibility of drug hypersensitivity reactions (including anaphylactic reactions) and take the necessary precautions [see Contraindications (4) , Adverse Reactions (6.1) ] . Potentially serious hypersensitivity reactions, including anaphylaxis, have occurred in patients treated with sugammadex. The nature and frequency of anaphylaxis and hypersensitivity associated with sugammadex administration were evaluated in a randomized, double-blind, placebo-controlled, parallel-group, repeat-dose study in which 375 subjects were randomized to receive 3 doses of sugammadex IV with a 5-week washout period: 151 subjects received 4 mg/kg, 148 received 16 mg/kg and 76 received placebo.

The frequency of anaphylaxis for the 299 healthy volunteers treated with intravenous sugammadex was 0.3% (n=1 in the sugammadex 16 mg/kg group on the first dose). Signs and symptoms included conjunctival edema, urticaria, erythema, swelling of the uvula and reduction in peak expiratory flow within 5 minutes of dose administration. The most common hypersensitivity adverse reactions reported were nausea, pruritus and urticaria and showed a dose response relationship, occurring more frequently in the 16 mg/kg group compared to the 4 mg/kg and placebo groups.

Anaphylaxis has also been reported in the post-marketing setting, including at doses less than 16 mg/kg. The most commonly described clinical features in reports of anaphylaxis were dermatologic symptoms (including urticaria, rash, erythema, flushing and skin eruption); and clinically important hypotension often requiring the use of vasopressors for circulatory support. In addition, prolonged hospitalization and/or the use of additional respiratory support until full recovery (re-intubation, prolonged intubation, manual or mechanical ventilation) have been noted in a number of the anaphylaxis reports.

5.2Marked Bradycardia Cases of marked bradycardia, some of which have resulted in cardiac arrest, have been observed within minutes after the administration of sugammadex [see Adverse Reactions (6.2) ] . Patients should be closely monitored for hemodynamic changes during and after reversal of neuromuscular blockade. Treatment with anticholinergic agents, such as atropine, should be administered if clinically significant bradycardia is observed.

5.3Respiratory Function Monitoring During Recovery Ventilatory support is mandatory for patients until adequate spontaneous respiration is restored and the ability to maintain a patent airway is assured. Even if recovery from neuromuscular blockade is complete, other drugs used in the peri- and post-operative period could depress respiratory function and therefore ventilatory support might still be required. Should neuromuscular blockade persist after sugammadex administration or recur following extubation, take appropriate… [Excerpted — this section continues on DailyMed.]

6 ADVERSE REACTIONS The following serious adverse reactions are described elsewhere in the labeling: Anaphylaxis and Hypersensitivity [see Contraindications (4) , Warnings and Precautions (5.1) ] Marked Bradycardia [see Warnings and Precautions (5.2) ] Most common adverse reactions (reported in ≥10% of adult patients at a 2, 4, or 16 mg/kg sugammadex injection dose and higher than the placebo rate): vomiting, pain, nausea, hypotension, and headache. (6.1 ) Most common adverse reactions (reported in ≥10% of pediatric patients 2 to <17 years of age at sugammadex injection doses of 2 or 4 mg/kg) were pain, vomiting, and nausea.

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adult Patients The data described below reflect 2914 subjects exposed to 2, 4, or 16 mg/kg sugammadex and 544 to placebo in pooled Phase 1-3 studies. The population was 18 to 92 years old, 47% male and 53% female, 34% ASA (American Society of Anesthesiologists) Class 1, 51% ASA Class 2, and 14% ASA Class 3, and 82% Caucasian.

Most subjects received a single dose of sugammadex 2 mg/kg or 4 mg/kg. Adverse reactions reported in ≥10% of patients at a 2, 4, or 16 mg/kg sugammadex dose with a rate higher than the placebo rate are: vomiting, pain, nausea, hypotension, and headache. All adverse reactions occurring in ≥2% of subjects treated with sugammadex and more often than placebo for adult subjects who received anesthesia and/or neuromuscular blocking agent in pooled Phase 1 to 3 studies are presented in Table 2.

7 DRUG INTERACTIONS Toremifene : Concomitant use can delay recovery. ( 7.2 ) Hormonal contraceptives : Patients must use an additional, non-hormonal method of contraception for 7 days following sugammadex injection administration. ( 5.6 , 7.3 )

7.1Summary The information reported in sections 7.2 – 7.4 is based on binding affinity between sugammadex and other drugs, preclinical experiments, clinical studies and simulations of a pharmacokinetic-pharmacodynamic (PK-PD) model. Based on these considerations, no clinically significant pharmacodynamic interactions with other drugs are expected, with the exception of toremifene and hormonal contraceptives.

7.2Interactions Potentially Affecting the Efficacy of Sugammadex Toremifene For toremifene, which has a relatively high binding affinity for sugammadex and for which relatively high plasma concentrations might be present, some displacement of vecuronium or rocuronium from the complex with sugammadex could occur. The recovery to TOF ratio to 0.9 could therefore be delayed in patients who have received toremifene on the same day of surgery.

7.3Interaction Potentially Affecting the Efficacy of Hormonal Contraceptives In vitro binding studies indicate that sugammadex may bind to progestogen, thereby decreasing progestogen exposure. Therefore, the administration of a bolus dose of sugammadex is considered to be equivalent to missing dose(s) of oral contraceptives containing an estrogen or progestogen. If an oral contraceptive is taken on the same day that sugammadex is administered, the patient must use an additional, non-hormonal contraceptive method or back-up method of contraception (such as condoms and spermicides) for the next 7 days.

In the case of non-oral hormonal contraceptives, the patient must use an additional, non-hormonal contraceptive method or back-up method of contraception (such as condoms and spermicides) for the next 7 days.

7.4Interference with Laboratory Tests Sugammadex may interfere with the serum progesterone assay. Interference with this test was observed at sugammadex plasma concentrations of 100 mcg/mL, which may be observed for up to 30 minutes after a 16 mg/kg dose.
