Clinical Trial Summary

The goal of this study is to compare pharmacy-based medication assisted treatment (MAT) with usual care MAT for people with opioid use disorder.

Description:

This study compares pharmacy-based medication assisted treatment (MAT) with usual care MAT. This will be the first study to use a randomized controlled trial design to test the multisite implementation of known effective interventions to treat opioid use disorder and prevent fatal opioid overdose (treatment with buprenorphine and natlrexone) in a community pharmacy setting. Understanding how this model can improve engagement in care within innovative systems of MAT delivery like the Rhode Island Centers of Excellence in MAT model as well as the more traditional office based opioid therapy (OBOT) arrangement, and for patients with shorter and longer time on stabilized MAT doses advances the science of addiction health services.

This study presents an opportunity to compare clinical outcomes of patients randomized to receive the same medications but in different settings that are equipped with differing levels of counseling expectations and access to wrap-around services. In this way, the trial helps to inform whether-and for whom--the limited support services in the pharmacy are sufficient to engage and retain patients in MAT, or if ready access to comprehensive services are necessary. Approximately 86% of Americans live within 5 miles of a pharmacy, making pharmacists the most accessible health care professionals. This model could redefine the role of the pharmacy.

The completed initial phase of the study (Phase 1) involved a pilot of the pharmacy MAT care model. The current phase of the study (Phase 2) is a randomized controlled trial comparing the pharmacy MAT care model to usual MAT care.

The aim of the current phase is to conduct a randomized controlled trial of 250 medication-stabilized (with BNX or NTX) patients with OUD receiving MAT care in Rhode Island, comparing engagement and clinical outcomes for patients followed up in a usual care model to those maintained and followed up in a pharmacy MAT care model.

Related Conditions & MeSH terms

• Opioid-Related Disorders
• Opioid-use Disorder

Intervention

Drug:
• buprenorphine/naloxone oral product
To treat opioid use disorder, buprenorphine/naloxone will be provided by a study pharmacist under a collaborative pharmacy practice agreement on a weekly or monthly basis, unless the care plan specifies greater frequency of pharmacy visit. The median expected dose of buprenorphine/naloxone (sublingual film or tablet) is 8 to 24 mg daily, and may be adjusted per the collaborative pharmacy practice agreement.
• injectable naltrexone
To treat opioid use disorder, injectable naltrexone will be provided by a study pharmacist under a collaborative pharmacy practice agreement on a monthly (injectable naltrexone) basis. The expected dose of injectable naltrexone will be approximately 380 mg. Injectable naltrexone will be dispensed and prepared by the pharmacist but administered by nursing staff for the pilot study.

Other:
• Pharmacy maintenance addiction care
Patients randomized to the pharmacy study arm and on a stable dose of buprenorphine/naloxone or naltrexone will receive maintenance care at the pharmacy for up to three months. Patients will visit for check-ins with a pharmacist on a monthly, weekly, or more frequent basis, depending on the individual treatment plan. Patients on buprenorphine/naloxone will be dispensed their medication at study visits, whereas patients taking injectable naltrexone will be dispensed it monthly by the pharmacist. All patients will visit the pharmacy at least monthly for addiction care (assessment, toxicological testing).

Drug:
• oral naltrexone
To augment care for patients receiving injectable naltrexone for the treatment of OUD and treat cravings that may arise before their scheduled injection, patients prescribed injectable naltrexone may be provided a several day supply of oral naltrexone by a study pharmacist under a collaborative pharmacy practice agreement. The expected dose of oral naltrexone will be approximately 25-50 mg daily.

Type	Measure	Description	Time frame	Safety issue
Other	Engagement in MAT	Proportion of patients with one or more visits during the first 30 days post randomization according to the medical or pharmacy record	up to 30 days post randomization
Primary	Retention in MAT	Proportion of patients attending one or more visits with MAT providers every 30 days for up to 90 days post randomization according to the medical or pharmacy record	up to 90 days post randomization
Primary	Relapse to drug use	Proportion of patients who relapse to drug use, defined as absence of the MAT medication and presence of heroin or other illicit opioids. Measured by toxicological (urine or oral) analysis, with samples collected at every visit (i.e.,	up to 90 days post randomization
Secondary	Primary care visits	Measured by patient self-report, patient medical record review, or by direct contact with the facility, clinician, or both.; The self report item asks: How many times did you visit your primary care provider (do NOT count visits to providers at the emergency department) in the past 90 DAYS (since starting this study)?; Never, no provider; Never, but I have a provider; Once or twice; 3-5 times; 6 or more times	up to 90 days post randomization
