The overarching objective of the SWIFT trial (CTN-0097) is to foster widespread adoption of a regimen for rapid initiation of treatment with extended-release injection naltrexone (XR-NTX) at inpatient or residential Community Treatment Programs (CTPs). If widely adopted, such a regimen would have a substantial public health impact by expanding medication treatment options offered to patients with OUD to include XR-NTX.
In multi-site, randomized (subject level) trials, XR-NTX, once initiated, has been found to have similar effectiveness to sublingual buprenorphine on clinical outcomes of retention in treatment and abstinence from opioids. However, initiation of naltrexone often involves a significant (up to 2 weeks) delay, which is a clinical hurdle that impedes the widespread adoption of XR-NTX as a treatment option. Initiation of naltrexone in patients actively using opioids requires that a patient be detoxified first, and the official prescribing information for XR-NTX recommends an additional 7- to 10-day waiting period after last dose of opioid before administering XR-NTX. This standard initiation regimen, involving a brief period of agonist, usually buprenorphine, taper followed by a 7- to 10-day waiting period, takes approximately two weeks. During this time, patients are vulnerable to drop out and relapse; further, this waiting period is problematic in the face of funding restrictions on the duration of inpatient stays. In a single-site randomized trial, a Rapid naltrexone induction method utilizing minimal buprenorphine, non-opioid medications to treat withdrawal symptoms, and upward titration of oral naltrexone starting with small doses, XR-NTX initiation was accomplished in 5 to 7 days and was found superior to the standard 14-day approach on the proportion of patients initiating XR-NTX.
The primary goal of this hybrid effectiveness-implementation study is to determine whether the Rapid method of initiating treatment with XR-NTX is non-inferior to a standard method on the primary effectiveness outcome of successful initiation of XR-NTX (receiving the first injection) when implemented at community-based inpatient or residential programs. Secondary objectives include comparing rapid versus standard method of XR-NTX initiation on: time from admission to first dose of XR-NTX and time to dropout, craving, withdrawal severity, retention, abstinence, and safety measures, as measured during the inpatient initiation process and the first two months post XR-NTX induction. Other exploratory outcomes include predictors of initiation success, and economic analyses. The implementation goal is to operationalize an implementation facilitation strategy that will be used to train clinical sites on the XR-NTX initiation method, to capture fidelity to the rapid induction process, and to study barriers and facilitators to implementation and refine the implementation facilitation strategy accordingly.
| Study Type : | Interventional (Clinical Trial) |
| Actual Enrollment : | 415 participants |
| Allocation: | Randomized |
| Intervention Model: | Crossover Assignment |
| Intervention Model Description: | The proposed study is an open-label, multi-center, stepped-wedge cluster randomized trial. As part of the stepped-wedge design proposed for this trial, one site, randomly chosen, will start implementing the Rapid procedure (RP) and will remain in this arm for the rest of the study. The next 4 sites randomly chosen will first implement the Standard procedure (SP), to establish the within-site comparison condition, and then at selected staggered time-points (steps) will switch to implementing only the RP. The 6th site (after 5 sites have been randomized to RP) will remain in the SP procedure arm throughout the whole duration of the study. Implementation of RP at study sites will be staggered by 14 weeks and the order in which sites will cross-over from SP to RP will be randomly chosen. |

Active Comparator: Standard Induction Method
The Standard Method (13-day long) includes 5-days of buprenorphine taper followed by 7-day washout period
|
Other: Standard Induction Procedure (SP)
SP includes stabilization on buprenorphine (6-8 mg) on Day 1 followed by a taper over the subsequent 4 days. After the completion of buprenorphine taper, participants will enter a washout period of at least 8 days. On the last day of the washout period, participants will be evaluated for eligibility to receive XR-NTX injection. Once found eligible, an XR-NTX injection will be given. |
|
Experimental: Rapid Induction Method
The Rapid Method includes one day of buprenorphine followed by a day of washout and 3-4 days of oral naltrexone titration with adjunctive medications
|
Other: Rapid Induction Procedure (RP)
RP includes 1 day of buprenorphine 6-8 mg, followed by a day of washout and 4 days of oral naltrexone titration. If the participant is able to tolerate the last dose of the naltrexone titration, an XR-NTX injection will be given |

3. Maintenance treatment with methadone. 4. Maintenance treatment with buprenorphine unless the patient is determined to have a poor treatment response (in the form of buprenorphine non-adherence with or without the use of illicit opioids), warranting change to XR-NTX treatment.
5. Presence of pain of sufficient severity as to require ongoing pain management with opioids.
6. Circumstances (legal, personal, occupational) that would threaten the feasibility of XR- NTX treatment or make another treatment (e.g. buprenorphine or methadone) a better choice.
7. Are currently in jail, prison or other overnight facility as required by court of law or have pending legal action that could prevent participation in study activities.
8. If female, currently pregnant or breastfeeding, or planning on conception. 9. Body habitus that, in the judgment of the study physician, precludes safe intramuscular injection of XR-NTX (e.g., BMI>40, excess fat tissue over the buttocks, emaciation).
10. Admitted to the inpatient detoxification or residential rehabilitation unit more than 3 days prior to consent.
