Clinical Trial Summary

Investigators will test a novel protocol for starting BUP (buprenorphine-naloxone) treatment. The BUP microdose induction protocol has participants start very low doses of BUP without stopping other opioids that they are taking. The treatment as usual (TAU) has participants stop other opioids and experience opioid withdrawal before starting BUP. Investigators propose to test BUP microdose inductions vs. TAU in a randomized controlled trial.


Description:

Investigators will conduct a hybrid type 1 effectiveness-implementation study, using a pragmatic, open-label, randomized controlled trial (RCT). Investigators will randomize 270 hospitalized patients with (a) chronic pain and (b) opioid misuse or opioid use disorder (OUD) to a 5-day BUP microdose induction protocol (without stopping full agonists) or 2-day standard induction (with stopping full agonists), and then link participants to outpatient BUP treatment when they are released from the hospital. Study assessment visits will occur at baseline, 1 week, and 1, 3, and 6 months. Assessments will include interviews and urine drug tests to determine whether participants start BUP, continue BUP, have improvements in pain and decrease illicit opioid use. During induction and 3-months of follow-up, investigators will also collect data on mobile devices to assess opioid withdrawal, opioid craving, pain, and anxiety. These data will allow investigators to assess whether BUP microdosing targets of engagement-opioid- and pain-related symptoms-mediate OUD outcomes. Exploratory analyses will also examine pain as a trigger for opioid relapse. Aim 1: To test the effectiveness of BUP microdose induction (vs. TAU) on OUD outcomes. H1: The microdose arm (vs. TAU) will have better BUP treatment uptake and retention, and less illicit opioid use. H2: Improvements in H1 will be mediated by opioid- and pain-related symptoms. Aim 2: To test the effectiveness of microdosing (vs. TAU) on pain outcomes. H3: The microdose arm (vs. TAU) will have less pain intensity and interference, and improved quality of life. H4: Improvements in H3 will be mediated by OUD outcomes. Aim 3: To inform future implementation and dissemination efforts, investigators will: 3a) Examine factors influencing reach, adoption, implementation, and maintenance of BUP microdosing. Investigators will use qualitative and quantitative methods to describe multi-level factors influencing these domains; 3b) Calculate the cost and examine cost-effectiveness of BUP microdosing. H5: Compared with TAU, BUP microdosing will be cost-effective from a societal and a health sector perspective.

Study Design


Intervention

Drug:
BUP microdose induction
Participants will be started on a 5-day BUP microdose induction protocol (without stopping full agonists). Day 1: participants will receive buprenorphine (Belbuca) 225 mcg mg every 12 hours Day 2: participants will receive buprenorphine (Belbuca) 450 mcg every 8 hours Day 3: participants will receive buprenorphine-naloxone 2-0.5 mg every 8 hours Day 4: participants will receive buprenorphine-naloxone 4-1 mg every 8 hours Day 5: participants will receive buprenorphine-naloxone 8-2 mg every 12 hours
TAU
2-day standard BUP induction protocol (with stopping full agonists) Day 1: hold all opioids Day 2: buprenorphine-naloxone 2-0.5 mg every 6 hours Day 3: buprenorphine-naloxone 8-2 mg every 12 hours
Behavioral:
Linkage to outpatient BUP treatment
Participants will be given an expedited appointment (within 2 weeks) to continue BUP treatment at a Montefiore community health center

Outcome

Type Measure Description Time frame Safety issue
Other Pain Intensity Mean pain intensity score, measured using the Brief Pain Inventory (BPI), will be reported for each study arm. 3 months
Other Pain interference Mean pain interference score, measured using the pain interference scale from the BPI, which is a 7-item instrument measuring the impact of pain on daily activities and physical functioning, will be reported for each study arm. 3 months
Primary BUP treatment uptake The percentage of participants who start BUP treatment, defined as receiving BUP 7 days after the baseline visit, will be reported for each arm. 7 days
Secondary Illicit opioid use The mean number of days of illicit opioid use, defined as self-reported use of heroin, fentanyl, or non-prescribed opioid analgesics in the prior 30 days based on the Addiction Severity Index, will be reported for each arm. 1, 3, and 6 months
Secondary BUP retention in care The percentage of participants who are retained in BUP treatment, defined as having a BUP prescription written 180-210 days (6-month retention) after enrollment, will be reported for each arm. 6 months
