Reversal Of Opioid Induced Respiratory Depression Intranasal Naloxone

ClinConnect Summary

This clinical trial is studying how well certain medications can help reverse breathing problems caused by opioid use, particularly in cases of overdose. The medications being tested are naloxone and nalmefene, which can be given either through the nose or intravenously (directly into the vein). The goal is to understand how these drugs work in both healthy volunteers and people who regularly use opioids, to improve treatment recommendations for emergencies related to opioid overdose.

To participate in this study, you need to be between 18 and 70 years old and either a healthy volunteer or a chronic opioid user taking a certain amount of prescribed opioids daily. Healthy volunteers should not have any history of substance use disorder or other serious medical conditions. Participants can expect to undergo various health evaluations and to receive these medications during the trial. It’s important to note that women who can become pregnant must have a negative pregnancy test and agree to use contraception during the study. Overall, this trial aims to find safer and more effective ways to treat opioid-related breathing issues.

  • 8. History or presence of allergic response to fentanyl, sufentanil or naloxone;
  • 9. Subjects who have demonstrated allergic reactions (e.g., food, drug, atopic reactions or asthmatic episodes) which, in the opinion of the Investigator and sponsor, interfere with their ability to participate in the trial;
  • 10. Treatment with another investigational drug within 3 months prior to dosing or having participated in more than 4 investigational drug studies within 1 year prior to screening;
  • 11. Site staff or subjects affiliated with, or a family member of, site staff directly involved in the study;
  • Chronic opioid users
  • 1. 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;
  • 2. Any active medical condition, organ disease or concurrent medication or treatment that may either compromise subject safety or interfere with study endpoints;
  • 3. Consume, on average, \>27 units/week of alcohol in men and \>20 units/week of alcohol in women (1 unit = 1 glass (250 mL) beer, 125 mL glass of wine or 25 mL of 40% spirit);
  • 4. Currently receiving medication-assisted treatment for the treatment of opioid-use disorder;
  • 5. Significant traumatic injury, major surgery, or open biopsy within the prior 4 weeks of informed consent;
  • 6. History of suicidal ideation within 30 days prior to informed consent or history of a suicide attempt in the 6 months prior to informed consent;
  • 7. Measured systolic blood pressure greater than 160 or less than 95 mmHg or diastolic pressure greater than 95 mmHg at screening;
  • 8. History or presence of allergic response to study medication;
