NCT05589181

Brief Summary

This project, involving two distinct clinical trials, tests whether induction to a higher than currently recommended buprenorphine (BUP) induction dose is safe and can improve the proportion of patients who engage in comprehensive addiction services within 7-day of induction. Trial 1 is a head-to-head comparison of the safety, tolerability and feasibility of high dose BUP induction (32 mg). The study involves two cohorts, (1) a 12mg cohort (standard) to determine baseline data and (2) a 32 mg (high dose) cohort. If the 32mg is intolerable, a 24 mg dose may be evaluated. Trial 2 is a small pilot multicenter randomized, double blinded, clinical trial in 80 participants (randomized 1:1) that will provide preliminary information on efficacy with the primary outcome being engagement in comprehensive addiction treatment 7-days post BUP induction. In collaboration with National Institute on Drug Abuse (NIDA), the research team have determined that there must be a minimum increase in engagement in comprehensive addiction treatment of 15% at 7-days in the high dose induction group to justify a larger future clinical trial.

Outcome Measures

Primary Outcomes (1)

  • The proportion of participants engaged in comprehensive addiction treatment at 7-days post-ED induction

    The proportion of participants engaged in comprehensive addiction treatment at 7 days post-ED induction as verified by participant and the addiction treatment program.

    7 days post-ED visit

Secondary Outcomes (12)

  • Percentage of days with opioid abstinence (Trial 1)

    at day 7

  • Percentage of days with opioid use (Trial 1)

    7 days post-ED

  • Percentage of days with opioid use (Trial 2)

    30 days post-ED

  • Daily assessment of opioid use (Trial 1)

    Days 1-7 after enrollment

  • Change in number of times opioids used (Trial 1)

    induction through 7 days

  • +7 more secondary outcomes

Study Arms (2)

Buprenorphine Standard Dose

ACTIVE COMPARATOR

The standard arm will receive an induction dose of 12mg of buprenorphine (BUP) split as 8mg at time=0 and 4mg at time=30-60 min.

Drug: Standard Buprenorphine Dose

Buprenorphine High Dose

EXPERIMENTAL

The experimental arm tests the safety and tolerability of 32mg of BUP split as 16mg at time=0 and 16mg at time=30-60 min as an induction dose.

Drug: High Dose Buprenorphine

Interventions

32mg of BUP split as 16mg at 0 minutes and 16mg at 30-60 min as an induction dose

Buprenorphine High Dose

12mg of buprenorphine (BUP) split as 8mg at 0 minutes and 4mg at time 30-60 min as an induction dose

Buprenorphine Standard Dose

Eligibility Criteria

  • Have prior enrollment in the current study
  • Have a known allergy or hypersensitivity to BUP
  • Have been engaged in formal addiction treatment in the 30-days prior to the ED visit (this does not include addiction treatment or residential programs where MOUD is not given (e.g. behavioral counseling, abstinence programs, NA)
  • Have received naloxone in the 60-minutes prior to the anticipated first transmucosal (TM) BUP administration
  • Is undergoing concurrent treatment with another investigational agent or enrolment in another clinical study

Model Details: The design of Trial 1 and Trial 2 will be described separately. Trial 1 is a prospective test of the safety and tolerability of 32 mg of BUP as an induction dose (split dosing over 30-60 minutes with 4 hours of post-induction monitoring) with the recommended BUP induction dose (12mg, also split over 60 minutes). Trial 2 is a four-site pilot RCT (n=20x4) conducted in the ED, that will test the efficacy, safety and tolerability of the high BUP dose (selected in Trial 1) as an induction dose (split dosing over 30-60 min) compared to standard BUP induction dose (up to 12mg) also split over 30-60 min.
