Details and patient eligibility


To evaluate the effect of ADV6209, a new oral Midazolam formulation, on preoperative anxiety and sedation levels in paediatric anaesthesia Primary Objective: Sedation score (mYPAS) 30 min after administration of the premedication drug Secondary Objective: Acceptance of anaesthesia mask induction Acceptance of oral administration of the premedication drug

Full description

Premedication represents an important part in the perioperative management of children and is used to reduce pre-operative stress as well as to facilitate induction of inhaled anaesthesia. Midazolam is the drug most often used for premedication in infants and children because it provides good sedation, anxiolytic and amnestic effects and few side effects. Oral intake of the drug is the most preferred route of administration by paediatric patients, whereas the majority of existing oral Midazolam solutions involve the use of i.v. Midazolam formulation given orally, unregistered or off-label. Moreover i.v. Midazolam solutions are often not well accepted by children because of their bitter taste. Considering the lack of available oral medications for moderate sedation in children in most European countries, ADV6209, an innovative 0.2% (w/v) oral solution of Midazolam for children from six months of age, was developed. The formation of a γ-Cyclodextrin -Midazolam complex, representing a new chemical formula, was used to improve the solubility and the palatability of the Midazolam formulation. A pharmacokinetic (PK) study has been executed in adults, children and adolescents, whereas ADV6209 showed improvements to current extemporaneous oral solutions of midazolam (EOM) preparations in terms of taste and easiness of use while presenting a similar PK profile. Satisfying sedation, measured with the Observer Assessment of Alertness/Sedation Scale (OAA score / S≤17) was observed in 78.4% of paediatric patients 30 minutes after ADV6209 administration. Anxiety score (modified Yale Preoperative Anxiety Scale - mYPAS) was decreased by 18.3% on average over baseline, 30 minutes after ADV6209 with a more pronounced effect in the youngest children who were also the most anxious prior to administration of the drug. In general the treatment was well accepted by all children and did not induce more crying and nausea / vomiting than before Midazolam. ADV6209 seems a very promising premedication drug. It has been licensed by the EU regulatory authorities to become the first licensed paediatric sedative in the EU (September 2018). It may help to avoid unregistered and off label use of EOM. Consequently, we want to evaluate the efficacy and safety of ADV6209 on preoperative anxiety and sedation levels in paediatric anaesthesia in daily clinical routine in this randomized, controlled, double blinded study.
