Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Efficacy

Compare the proportion of patients experiencing at least one psychodysleptic effect in the control and active groups during the first hour of treatment.

Secondary objectives 3

  1. Assess the intensity of psychodysleptic effects described by patients
  2. Compare the analgesic efficacy of the 2 molecules during the first hour of treatment: evolution of EN pain scores over time ; proportion of patients reporting relief (EN≤3/10); rate of recourse to additional analgesia (“rescue analgesia”).
  3. Define the proportion of other possible adverse effects or abnormal vital constants measured every 15 minutes from t0 to t0 + 60 minutes

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 4

  1. adult patients aged 18 or over
  2. patient consulting our department for a medical or traumatic pathology responsible for acute (less than 7 days old) and severe pain (greater than or equal to 6 on the EN pain scale, which has 11 levels: from 0 = no pain to 10 = maximum imaginable pain)
  3. patient has given free and informed consent
  4. patient affiliated to a social security scheme

Exclusion criteria 14

  1. inability to quantify pain score
  2. proven or suspected intoxication (drug or alcohol intoxication) leading to consciousness disorders (Glasgow score less than or equal to 15)
  3. person under legal protection or deprived of liberty
  4. pregnant or breast-feeding patients
  5. known allergy to ketamine or esketamine
  6. history of drug addiction or dependence
  7. inadequately controlled hyperthyroidism
  8. history of stroke
  9. severe heart failure
  10. existing intracranial hypertension, glaucoma or ocular trauma
  11. unstable vital signs (systolic blood pressure < 90 mmHg or > 180, heart rate < 50 per minute or > 150, respiratory rate < 10 per minute or > 30)
  12. chronic treatment with aminophylline, theophylline or methylergometrine
  13. administration of morphine within one hour of inclusion
  14. simultaneous participation in another study that could interfere with the treatment studied or the results of the statistical analysis

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. Proportion of patients experiencing at least one psychodysleptic effect, in the control group (ketamine IV 0.3 mg/kg) and in the active group (esketamine IV 0.15 mg/kg). We used the SERSDA (Side Effects Rating Scale for Dissociate Anesthetics) scale, the most widely used in studies, with 9 items. The presence of one of these 9 items will be assessed by patients every 5 minutes from t0 (start of infusion) to t0 + 60 minutes.

Secondary endpoints 3

  1. Assess the intensity of psychodysleptic effects described by patients
  2. Compare the analgesic efficacy of the 2 molecules during the first hour of treatment: evolution of EN pain scores over time ; proportion of patients reporting relief (EN≤3/10); rate of recourse to additional analgesia (“rescue analgesia”).
  3. Define the proportion of other possible adverse effects or abnormal vital constants measured every 15 minutes from t0 to t0 + 60 minutes.
