Trial Outcomes & Findings for A Study to Evaluate the Incidence of Hypersensitivity After Administration of Sugammadex in Healthy Participants (MK-8616-101) (NCT NCT02028065)

NCT ID: NCT02028065

Last Updated: 2019-04-03

Results Overview

The investigator or designated clinician performed a targeted hypersensitivity assessment (THA) in each participant at 0.5, 4 and 24 hours after each dose for each dosing period. The THA could also be performed at other times if possible hypersensitivity signs were observed. The THA included elicitation of symptoms as well as examination of the participant, covering neurologic, pulmonary, cardiovascular, gastrointestinal and dermatologic domains. Each potential hypersensitivity case identified by the presence of any sign or symptom in a pre-defined list of hypersensitivity signs and symptoms that were found through the THA was reviewed by an independent, blinded adjudication committee, which determined whether the referred case was a case of hypersensitivity (yes/no). In addition, all adverse events (AEs) occurring in study were reviewed for terms associated with hypersensitivity or anaphylaxis, and could also result in referral to the adjudication committee for evaluation.

Participant Flow

One participant who was randomized to sugammadex 16 mg/kg instead received 3 doses of placebo and completed study. This participant appears in sugammadex 16 mg/kg column in Participant Flow period "Randomization through Start Treatment" and in placebo column in period "Treatment through Study Completion."

PRIMARY outcome

Timeframe: Up to approximately 28 days after last dose (approximately 14 weeks)

Population: APaT - All randomized participants who received at least one dose of study treatment, with each participant included in arm corresponding to treatment actually received.

The investigator or designated clinician performed a targeted hypersensitivity assessment (THA) in each participant at 0.5, 4 and 24 hours after each dose for each dosing period. The THA could also be performed at other times if possible hypersensitivity signs were observed. The THA included elicitation of symptoms as well as examination of the participant, covering neurologic, pulmonary, cardiovascular, gastrointestinal and dermatologic domains. Each potential hypersensitivity case identified by the presence of any sign or symptom in a pre-defined list of hypersensitivity signs and symptoms that were found through the THA was reviewed by an independent, blinded adjudication committee, which determined whether the referred case was a case of hypersensitivity (yes/no). In addition, all adverse events (AEs) occurring in study were reviewed for terms associated with hypersensitivity or anaphylaxis, and could also result in referral to the adjudication committee for evaluation.

SECONDARY outcome

Timeframe: Up to approximately 28 days after last dose (approximately 14 weeks)

Population: APaT - All randomized participants who received at least one dose of study treatment, with each participant included in arm corresponding to treatment actually received.

The investigator or designated clinician performed a THA in each participant at 0.5, 4 and 24 hours after each dose. The THA could also be performed at other times if possible hypersensitivity signs were observed. Each potential hypersensitivity case identified by presence of any sign or symptom in a pre-defined list of hypersensitivity signs and symptoms that were found through the THA was reviewed by an independent, blinded adjudication committee, which determined whether the referred case was a case of anaphylaxis (yes/no) using Sampson Criterion 1 - Acute onset of an illness with involvement of the skin, mucosal tissue or both, and at least one of the following: a) respiratory compromise, b) reduced blood pressure or associated symptoms of end-organ dysfunction (J Allergy Clin Immunol 2006;117:391-397). All AEs occurring in study were reviewed for terms associated with hypersensitivity or anaphylaxis, and could also result in referral to the adjudication committee for evaluation.
