A Randomized Controlled Trial of
OROS-MPH + CBT in Adolescents
with ADHD and Substance Use Disorders
Robert Davies, M.D.
Associate Professor, Psychiatry
University of Colorado Denver School of Medicine
Financial Disclosures
• Active medication and placebo
provided by McNeil Pharmaceuticals
• Dr. Davies previously participated on
Speaker’s Bureaus for Eli Lilly, Pfizer
Background & Significance
• ADHD 3-5x more common in adolescents
with SUD (30-50%) compared to those
without SUD (7-10%) and is associated with
poorer treatment outcomes
• The safety and efficacy of psychostimulant
medication for ADHD in youths without
SUD is well-established, but research is
lacking in substance abusing adolescents
with ADHD
Study Aims
Aim 1: To evaluate the efficacy of OROS-MPH
vs. placebo in treating ADHD is substanceabusing adolescents
Aim 2: To evaluate the impact of OROS-MPH
+ CBT vs. placebo + CBT on substance
treatment outcomes
Aim 3: To evaluate the tolerability, safety, and
abuse potential of OROS-MPH in substanceabusing adolescents with ADHD

Summary of
Main Study Findings
1.
ADHD outcomes as good or better than in adolescents
without SUD
2.
OROS-MPH safe, well-tolerated
3.
Results suggest contribution of CBT to both SUD and ADHD
outcomes
4.
Substance outcomes as good or better than in youth with
less severe psychopathology
5.
Treatment compliance, completion superior to that reported
in studies of youths with less severe SUD and
psychopathology
Interpretation of Results in
Context of Previous Research
Results are inconsistent
• With most controlled trials of psychostimulant
vs placebo (alone) for ADHD
Results are consistent
• With 3 controlled psychostimulant trials in
adults concurrently receiving weekly individual
CBT for SUD (Levin et al 2006; 2007; Schubiner
et al 2004)
• With growing literature that cognitive behavioral
and behavioral interventions effective for ADHD
in adults and youth without SUD (Safren et al,
2005; Fabiano et al, 2009; Solanto et al, 2010)
If replicated, results have
important clinical implications
• Results suggest that clinically significant reductions in cooccurring ADHD symptoms may be important in helping
adolescents achieve greater abstinence during substance
treatment.
• In the context of individual CBT (for SUD), significant
reductions in ADHD symptoms may occur with or without
pharmacotherapy.
• If ADHD does not improve early in treatment, OROS-MPH
may be considered as safe and likely effective
pharmacotherapy for ADHD even if not yet abstinent (with
regular monitoring and in the context of ongoing substance
treatment)
• OROS-MPH demonstrated low abuse/diversion liability.
• Secondary outcomes indicated some added benefit with
OROS-MPH compared to placebo
