E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine the clinical and cost effectiveness of a personalised behavioural intervention (PBI) compared to treatment-as-usual (TAU) at achieving heroin and cocaine abstinence and health economic outcomes after 12 weeks of PBI, among initially non-responsive patients enrolled in Opiate Substitution Treatment (methadone [MMT]; Suboxone [SMT] (according to clinical preference) in a specialist NHS addictions treatment centre. |
|
E.2.2 | Secondary objectives of the trial |
A. Are there identical treatment retention and psychological therapy adherence rates between PBI and TAU arms of the study?
B. Are there identical heroin and cocaine craving, and other clinical functioning response profiles between the PBI and TAU arms?
C. What are the longer-term treatment and addiction recovery outcomes for patients receiving PBI and TAU over 5 years, and can biomarkers of differential clinical response be identified? |
