Clinical Trial Summary
To test the feasibility and acceptability of a novel approach for improving the delivery and
effectiveness of XRNTX treatment for opioid use disorder (OUD) - the MAT-PLUS intervention.
The components of the MAT-PLUS intervention are: XRNTX, initiated during an episode of
inpatient/residential treatment and dosed monthly, provides opioid receptor blockade, relapse
prevention and overdose prevention; Significant other engagement empowers family members or
other designated concerned others, providing concrete guidance for monitoring, supervision,
and improving adherence for their loved one in treatment; Assertive outreach incorporates
frequent multi-channel outreach, in a model that specifically targets engagement and
motivation for medication adherence; Counselor care coordination and case management focused
on medication management and adherence. This objective #1 will be accomplished by conducting
a small-scale, 2-arm, open label, RCT pilot study of 4 months of treatment with the MAT-PLUS
intervention (significant other engagement and training, medication care coordination by
counselors, assertive outreach) + TAU (monthly doses of XRNTX + routine counseling), vs TAU
for n=40 (20 per arm) patients with OUD. Adult patients ages 18+ who receive an initial dose
of XRNTX during an index episode of inpatient/residential/detox treatment for opioid
addiction at a public-sector community treatment program treatment, with intention to
continue in outpatient treatment. The experimental arm will receive the MAT-PLUS intervention
for 4 months of ongoing outpatient treatment with XRNTX. The control arm will receive 4
months of standard TAU (XRNTX + clinic-based counseling) without MAT-PLUS. At the beginning
of the trial an additional small (N = 4 or 5) group of test patients will receive the
MAT-PLUS intervention to test and refine the study procedures.
Description:
Residential detox is an ideal opportunity for initiation of relapse prevention medication,
particularly XRNTX, which requires some delay after recent opioid use. But concerns from the
field emphasize barriers to induction (as highlighted by the recent results of the CTN51 XBOT
study), poor adherence and retention. Clarification is needed on optimal delivery, including
a psychosocial treatment platform that is focused more specifically on medication adherence
through engagement and empowerment of significant others, and through training and
supervision of counselors. Adherence in non-research conditions has been a barrier. To
address these gaps, it is proposed this robust intervention, incorporating XRNTX into a
multi-component model of care emphasizing adherence enhancement. Assertive outreach is a
well-described intervention that is effective in chronic illness, eg in the Assertive
Community Treatment (ACT) model for serious and persistent mental illness, and the Integrated
Dual Disorder Treatment (IDDT) model for co-occurring disorders. Significant other
involvement is a well-established method of improving adherence (e.g. in Network Therapy and
Community Reinforcement Approach and Family Training). Significant other involvement is also
built into the standard Medication Management model (used in XBOT,COMBINE and others) but it
has not been actually used in most implementations. Finally, the use of counselors to drive
medication adherence takes advantage of the typically greater contact and alliance that
counselors have with patients compared to medical staff.
Several adherence enhancement components are combined synergistically: XRNTX, initiated
during residential treatment and dosed monthly; significant other engagement empowers
caregivers, providing guidance for encouragement, monitoring and supervision of medication
adherence; Assertive outreach incorporates frequent multi-channel contact, case management;
Counselor role clarification, training and supervision provides a clear focus on medication
adherence.
Primary outcome for this objective is # of doses of XRNTX received within the planned 4
months duration of outpatient treatment. The primary analysis will be a comparison of the
mean # of doses in the intervention compared to the control group. Additional analyses will
include comparisons of % of subjects receiving all 4 doses, % of subjects receiving at least
1 dose as outpatients as a demonstration of linkage from inpatient to outpatient treatment.
Secondary outcomes for this feasibility objective include process outcomes for feasibility
and acceptability, including: # and type of outreach attempts (phone call, email, text,
facebook message, etc) and successful contacts with patients and significant others,
utilization of TAU counseling, rates of return to treatment after dropout. Lastly,
assessments of satisfaction and significant other involvement will be obtained through focus
groups conducted separately with patients and significant others to assess qualitative
acceptability factors, both barriers and facilitators to success.
