Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Pharmacodynamic, Pharmacokinetic, Safety

The number IM and IN administrations needed to restore ventilation to baseline levels in healthy volunteers

Secondary objectives 4

  1. The number IM and IN administrations needed to restore ventilation to baseline levels in chronic opioid users
  2. Naloxone-induced changes in minute ventilation, end-tidal PCO2 and plasma concentrations of naloxone upon naloxone (either IM or IN) administration as a function of time.
  3. Naloxone and fentanyl pharmacokinetics
  4. Effect of fentanyl and naloxone on pupil diameter and muscle tone

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 3

  1. Aged 18-65 years with body mass index 19-40 kg/m2
  2. Opioid users: use opioids at daily doses ≥ 60 mg oral morphine equivalents. . No upper limit is set as would like to study an as large as possible range of opioid use. It is our experience that the majority of patients uses 60-600 mg oral morphine equivalents.
  3. Opioid users: • Stable as defined by the Investigator, based on a medical evaluation that includes the subject’s medical and surgical history, physical examination, vital signs, 12-lead ECG, hematology, and blood chemistry.

Exclusion criteria 8

  1. A medical history of medical or psychiatric disease (incl. drug or alcohol addiction);
  2. • Pregnancy or lactation
  3. • A positive drug urine dipstick on the screening or study days
  4. • History or presence of allergic response to study medication
  5. for chronic opioid users: • Currently meet the criteria for diagnosis of moderate or severe substance use disorder according to the DSM-5 criteria on any substances other than opioids, caffeine, or nicotine;
  6. Chronic opioid users: Any active medical condition, organ disease or concurrent medication or treatment that may either compromise subject safety or interfere with study endpoints;
  7. Chronic opioid users: Currently receiving medication-assisted treatment for the treatment of opioid-use disorder;
  8. Treatment with mixed agonists-antagonists (such as buprenorphine) or use of benzodiazepines.
