NCT04582786

Brief Summary

This study aims to evaluate the analgesic effect and the safety of 4 doses of STR-324 administered as an infusion, with or without initial bolus, to patients suffering from post-operative pain. The sensitivity of the pain model used in the trial will be evaluated with a standard group treated with morphine under the usual care conditions.

Outcome Measures

Primary Outcomes (2)

  • Qualitative Change of Pain Intensity

    Pain Intensity will be assessed by a Numerical Rating Scale (NRS) before and during analgesic infusion. Change of Pain Intensity assessed by the Numerical Rating Scale (NRS) after initiation of the post-op analgesia and before switch to standard treatment. The following parameter will be assessed: \- Qualitative: a decrease of 2 units minimum from baseline and/or achievement of a pain score ≤ 3 is considered successful, responder=Yes.

    On and/or after study drug, with fixed timepoints at 5, 10, 15, 20, 30, 45, 60, 75, 90, 105 and 120 minutes. If re-titration is required/performed, additional 5-minutes interval timepoints shall be added.

  • Quantitative Change of Pain Intensity

    Pain Intensity will be assessed by a Numerical Rating Scale (NRS) before and during analgesic infusion. Change of Pain Intensity assessed by the Numerical Rating Scale (NRS) after initiation of the post-op analgesia and before switch to standard treatment. The following parameter will be assessed: \- Quantitative: maximum value of the pain score difference versus baseline.

    On and/or after study drug, with fixed timepoints at 5, 10, 15, 20, 30, 45, 60, 75, 90, 105 and 120 minutes. If re-titration is required/performed, additional 5-minutes interval timepoints shall be added.

Secondary Outcomes (1)

  • Adverse events collection

    AEs collected directly after surgery until at least 30 days after the day of surgery.

Eligibility Criteria

Age18 Years - 64 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • NRS-measured pain intensity ranging from 4 to 8 inclusive at baseline PACU measurement;
  • With a sedation score ≤ S1 (awake or intermittently sleepy) at the time of pain assessment.

You may not qualify if:

  • Patient contra-indicated for morphine administration;
  • Unstable or poorly controlled psychiatric condition (e.g., untreated PTSD, major anxiety, or depression). Subjects who take stable doses (same dose \>30 days) of antidepressants and/or anti-anxiety drugs may be included;
  • Women who are pregnant or breastfeeding;
  • History of alcohol, opiate or other drug abuse.
  • Evidence of any active or chronic disease or condition that could interfere with, or for which the treatment might interfere with the conduct of the study, or that would pose an unacceptable risk to the subject in the opinion of the investigator. Minor deviations of values from the normal range may be accepted, if judged by the Investigator to have no clinical relevance;
  • Clinically significant abnormalities, as judged by the investigator, in laboratory test results;
  • Participation in an investigational drug or device study within 1 month prior to dosing.
