Assessing the Acceptability, Feasibility, Effectiveness and Cost-effectiveness of LADB

Detailed Description
Despite the proven effectiveness of opioid agonist maintenance treatment (OAMT), its coverage and use remain low globally and, particularly, in low- and middle-income countries (LMIC), in part due to challenges related to limited choice of OAMT medication and dosing options. The long-acting depot buprenorphine (LADB) formulation of OAMT, with either weekly or monthly administration, could provide a more discreet, convenient, and less stigmatizing form of treatment and the potential to improve client retention in care, as well as economic stability. It therefore may address unmet need among individuals who could benefit from OAMT and are not already taking it or who would prefer a long-acting option over current OAMT options. Studies have demonstrated the effectiveness and acceptability of LADB among those with opioid dependence in high-income settings. However, there are no known such studies conducted in LMIC.
The aim of the study is to determine the acceptability, feasibility, effectiveness, public health impact, and cost-effectiveness of introducing LADB in a range of LMIC.
The study will collect data from participants with opioid use disorder, service providers, and health policymakers/decision-makers across seven diverse LMIC: Egypt, India, Kyrgyzstan, South Africa, Tanzania, Ukraine, and Vietnam.
This is a multicenter, mixed-method study designed with community engagement and co-production. The study consists of four interlinked modules: Module 1 (feasibility) includes a process evaluation to monitor implementation and assess barriers, drawing on program data and interviews with service providers and other key stakeholders; Module 2 (effectiveness) involves a prospective cohort choice study among people with opioid dependence, initiating LADB and following up over 48 weeks; Module 3 (values and preferences, plus acceptability) includes key informant interviews and focus group discussions with people with opioid dependence to understand overall acceptability, values, preferences, experiences, and concerns relating to LADB; Module 4 (public health impact and cost-effectiveness) involves modeling based on collected data to estimate impact and cost-effectiveness of LADB in LMIC settings.

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
PWID who opt for LADB
People with opioid dependence who opt to initiate LADB across a range of LMIC settings over a 48-week period
|
The intervention will measure patient-centered outcomes in people initiating LADB among a cohort of opioid-dependent PWID across sites in the seven project LMIC.
Study participants will be enrolled from selected clinics that deliver routine opioid agonist maintenance treatment to PWID.
The intervention will 1) Compare characteristics at baseline of those service clients who do and do not initiate LADB in relation to demographic characteristics, history of drug use, and outcomes; 2) Measure side effects and adverse events among those initiating LADB; and 3) Where appropriate, assess changes in outcomes between time of LADB initiation and 48 week follow-up, including HCV and HIV testing and treatment, quality of life, employment opportunities, and service preferences.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Treatment Satisfaction Questionnaire for Medication 1.4 assessed through patient reported outcomes on effectiveness, side-effects, convenience and global satisfaction in relation to the medication
Time Frame: 48 weeks
|
The primary measure for treatment satisfaction will be collected through the Treatment Satisfaction Questionnaire for Medication 1.4 at 48 weeks.
This is a generic measure of treatment satisfaction with medication.
It has 14 questions divided into subscales (effectiveness; side effects, convenience and global satisfaction).
Response are on a Likert-scale of 5 or 7 points except for 1 yes/no question on the presence of side effects.
The scores are calculated for each of the subscales, which range from 0 to100 with higher scores indicating higher patient satisfaction with medication.
|
48 weeks
|
Retention in Care
Time Frame: 48 weeks
|
The primary measure for retention in care will be estimated as the proportion of people on LADB at 48 weeks
|
48 weeks
|
Nonmedical opioid use
Time Frame: 48 weeks
|
Assess degree of non-medical opioid use in the last month measured at week 48, in terms of number of days that non-medical opioids were not used in the last 4 weeks.
|
48 weeks

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
% of participants who have received testing for HIV and Hepatitis C (HCV) at 48 weeks, frequency of testing, % testing positive for antibodies to HIV or HCV and % linked to treatment and % retained into treatment
Time Frame: 48 weeks
|
Retention into HIV treatment will be measured through self-report using a predefined threshold of adherence (80 to 100%) in consultation with sites as well as through recoding return visits for medication refills.
