  1. The study's listed conditions name Opiate Overdose, a narrower term within Opioid-Related Disorders.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

This pilot study will evaluate the feasibility and clinical utility of extended-release injectable buprenorphine (XR-BUP) for the treatment of opioid use disorder (OUD) among individuals at high-risk for overdose (OD).

Read the detailed description

FASTER-BUP is a 24-week observational pilot study evaluating the feasibility and clinical utility of XR-BUP (brand name: Sublocade) for the treatment of OUD among individuals at high-risk of OD. Forty participants with moderate to severe OUD starting treatment with XR-BUP as part of standard of care will be followed.

In context

Opiate Overdose Reclassified

70 studies on the registry are indexed under Opiate Overdose; 11 are open to participants now.

This study's planned enrollment of 40 is below the median of 284 across 16 observational studies indexed under Opiate Overdose.

Lead sponsor

BC Centre on Substance Use is the lead sponsor of 3 studies on the registry; 2 are open to participants now.

Compared within Opiate Overdose, this study's primary condition as ClinicalTrials.gg classifies it; the registry's first condition term is Opioid-Related Disorders. The counts are of registry records indexed under each term, refreshed daily. How we classify →

Study population

Approximately 40 eligible participants are planned to be enrolled into the study. Interested individuals must meet all of the inclusion criteria and none of the exclusion criteria to be eligible for the study.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

Participants must meet ALL the following criteria to be eligible to participate for the study:

  1. Be above 19 years of age;
  2. Be diagnosed with moderate or severe OUD as evidenced by their approval for treatment with XR-BUP (Sublocade);
  3. Be at high-risk for recurrent overdose, defined as having experienced a recent non-fatal overdose within the past 6 months (e.g., admission to the emergency department for an overdose OR self-reported OD that required Naloxone administration OR had an overdose where an ambulance arrived at the scene);
  4. Have a new prescription for XR-BUP, but have not yet initiated treatment;
  5. Be able and willing to follow study procedures;
  6. Be able to provide adequate locator information (e.g., phone number and at least one emergency contact);
  7. Be able and willing to provide written ;
  8. Be able to understand, communicate and speak with the research staff. Non-English speaking individuals will require a translator to be present during all study visits and during all study activities. The translator will be independent (e.g., not known to the participant to prevent the risk for coercion or misrepresentation).

Exclusion criteria

Exclusion Criteria:

Participants will be excluded from the study if ANY of the following criteria are met:

  1. Be on OAT other than buprenorphine/naloxone in the 7 days prior to screening;
  2. Be on a stable buprenorphine/naloxone dose for more than 27 days prior to screening;
  3. Use of an drug in the 30 days prior to screening;
  4. Incarcerated, pending legal action or other reasons that might prevent completion of the study.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Groups and cohorts

  • Sublocade

    The only group consists of participants with moderate to severe OUD who will be starting treatment with extended-release injectable buprenorphine as part of standard of care. While individual treatment regimens may vary, these will often consist of 2 once-monthly 300 mg subcutaneous injections followed by 4 once-monthly 100 mg subcutaneous injections. However, participants may receive once-monthly 300 mg subcutaneous injections in place of 100 mg subcutaneous injections for as many months as is deemed necessary by their prescribing physician.

What researchers measure

Primary outcomes

  1. Number of XR-BUP injections received

    The primary outcome for this study will be retention in treatment, defined as having received the six scheduled XR-BUP injections and completed the EOS/Early Termination visit.

    Time frame: 24 weeks

  2. Proportion of treatment-engaged visits per participant

    Proportion of treatment-engaged visits per participant will be calculated as the number of received XR-BUP injections divided by the number of scheduled injections (i.e., six).

    Time frame: 24 weeks

Secondary outcomes

  1. Percentage of opioid free weeks

    Suppression of illicit opioid use will be measured as the percentage of opioid-free weeks during the active treatment period (Visit 2 to Visit 8), using a combination of Urine Drug Test (UDT) results and self-reported illicit opioid use.

    Time frame: 24 weeks

  2. Safety monitoring

    Descriptive statistics will be used for all safety analysis variables. No formal inferential tests will be performed on safety data. The incidence of all AEs will be summarized by body system, severity, seriousness, and relationship to the study drug using MedDRA. SAEs will be tabulated by patient. Descriptive statistics will be reported for injection site grading.

    Time frame: 24 weeks

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 17, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
