Title: Workshop on Adaptive Treatment Strategies


1
Workshop on Adaptive Treatment Strategies
  • Janet Levy, Ph.D.
  • Jim McKay, Ph.D.
  • Carl Pieper, Dr.Ph.
  • Madhukar Trivedi, M.D.

2
Purpose
  • EDUCATIONAL What are adaptive treatment
    strategies (dynamic treatment regimes)?
  • THOUGHT PROVOKING How might they be applied
    within the community of treatment providers
    within our network?

3
Agenda
  • Introductions Janet Levy
  • Experimental Designs Carl Pieper
  • Adaptive Treatment Strategies in
  • The Addictions Jim McKay
  • Mental Health Madhukar Trivedi
  • The CTN Janet Levy
  • Closing Janet Levy

History
Innovations in the design of clinical trials have
been in the service of pharmaceutical companies
to facilitate drug development. The results
OFTEN do NOT inform clinical practice,
especially in mental health.
A less considered aspect of the usual
placebo-controlled non-equivalence design is the
disparity between the decisions that it supports
and those that pervade clinical practice p.
3250, Dawson and Lavori(2004).
5
History
Development of CTN0030, a trial for the treatment
of prescription opioid dependence began in
2004. Team wanted to design a study which would
be practical (i.e. inform clinical
practice). Idea of re-randomizing those who
relapse during detoxification surfaced quickly
(to support inferences about which treatment is
best following relapse). How to frame the
primary hypothesis? Is it about the first phase
(detoxification?) OR is it about what to do for
those who relapse early? We struggled, the DSMB
struggled!!
6
History
Work illustrating how one might design trials to
support the development of clinical strategies in
addiction and mental health was just beginning to
be published in 2004!! Dawson, R. and Lavori,
P.W. (2004) Discuss the need for innovations in
trial design to inform clinical practice.
Murphy, S.A. (2005). Presents preliminary
sample size formulae to test hypotheses about
strategies in a trial using multiple
randomizations. Presents actual simple trial
designs. Murphy, S.A. et al, (with McKay, J.R.),
(2006 and 2007). Provides further thinking around
how to construct adaptive treatment strategies
and how to design trials specifically for the
development of long terms strategies.

The Promise of Adaptive Treatment Strategies
  • Help with adherence/drop out in out trials!!!
  • Treat adherence/drop out as another
  • Intermediate outcome
  • Indication for a different treatment
  • Opens up the potential for including MANY more
    patients in our trials
  • Vehicle for Integrated Care
  • Use psychosocial treatments to facilitate Meds ?
  • Use meds to facilitate psychological effects?
  • Vehicle for Stepped Care

Questions about Clinical Decisioning in the CTN
1a. In your clinical practice, what clinical
signs indicate that A client is not responding
well to treatment?
12
Questions about Clinical Decisioning in the CTN
1b. In your program, what treatment options are
available when the client is not responding to
standard care, or the first treatment he/she is
provided?
13
Questions about Clinical Decisioning in the CTN
1c. In your clinical practice, what clinical
signs indicate that a client is responding well
to treatment?
14
Questions about Clinical Decisioning in the CTN
1d. In your program, when the patient is doing
well, what treatment options are available
besides more of the same or discharge?
15
Questions about Clinical Decisioning in the CTN
2. Based on your own experience as a clinician,
which clinical decisions about patient care are
the most challenging (for any reason)?
16
Questions about Clinical Decisioning in the CTN
3. Based on your own experience as a clinician,
which clinical decisions are in most need of
empirical research (for any reason)?
17
Questions about Clinical Decisioning in the CTN
4. What do you do when a patient returns to
treatment several times without a prolonged
period of success between treatments?
18
Questions about Clinical Decisioning in the CTN
5. How long would you continue to apply a
particular treatment to a client before
determining whether or not the treatment is
successful?
