Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Number of Participants With at Least one Treatment-emergent Adverse Event (TEAE)
Secondary outcome measures
AUClast: Area Under the Plasma Concentration-time Curve From Time 0 to the Time of the Last Quantifiable Concentration for Danavorexton

Ceoi: Observed Plasma Concentration at the end of Infusion for Danavorexton

Trial Design

4Treatment groups
Experimental Treatment
Group I: Cohort P: Danavorexton TBDExperimental Treatment3 Interventions
Danavorexton dose to be decided (TBD) or danavorexton placebo-matching infusion, once, intravenously on Day 1 in healthy adult participants with intravenous propofol as induction and primary maintenance anesthetic. Dose of danavorexton will be based on the review of observed safety and tolerability data and pharmacokinetic (PK) data of previous cohorts.
Group II: Cohort A3: Danavorexton High DoseExperimental Treatment4 Interventions
Danavorexton high dose or danavorexton placebo-matching infusion, single, intravenously on Day 1 in healthy adult participants with intravenous propofol as induction anesthetic and inhaled sevoflurane as the primary maintenance anesthetic.
Group III: Cohort A2: Danavorexton Middle DoseExperimental Treatment4 Interventions
Danavorexton middle dose or danavorexton placebo-matching infusion, once, intravenously on Day 1 in healthy adult participants with intravenous propofol as induction anesthetic and inhaled sevoflurane as the primary maintenance anesthetic.
Group IV: Cohort A1: Danavorexton Low DoseExperimental Treatment4 Interventions
Danavorexton low dose or danavorexton placebo-matching infusion, once, intravenously on Day 1 in healthy adult participants with intravenous propofol as induction anesthetic and inhaled sevoflurane as the primary maintenance anesthetic.
