Clinical Trial Summary
The study will employ a randomized longitudinal clinical trial design to evaluate the
relative efficacy of a blinded hypnotic tapering protocol when used in combination with
therapist delivered Cognitive Behavioral Therapy for Insomnia (CBTI) for enhancing hypnotic
discontinuation rates. A blinded SMT+CBTI intervention will be compared to open-label
SMT+CBTI.
Description:
Treatment-seeking insomnia sufferers most often present in primary care venues where the
first and usually only treatment is a prescription for a sedative hypnotic, typically a
benzodiazepine (BZD) or newer benzodiazepine receptor agonist (BzRA). For some patients,
short-term or intermittent hypnotic use provides satisfactory insomnia relief. However, more
than 65% of individuals who are prescribed hypnotics use them for more than a year, and > 30%
remain on these agents for more than five years. Whereas some patients may appreciate partial
or full relief of insomnia symptoms with ongoing hypnotic use, continuous long-term use of
these agents may not represent optimal therapy. Many insomnia patients who participate in
non-drug insomnia therapy such as cognitive behavioral insomnia therapy (CBT-I) achieve
sustained insomnia remission long after a time-limited course of treatment. However, it is
difficult for most long-term hypnotic users to convert from use of medications to a
self-management approach. Interventions that combine CBT-I with supervised medication
tapering (SMT) have shown the greatest promise for achieving this outcome, but almost 50% of
patients who receive this assistance either fail to discontinue their hypnotics or return to
them even if they do achieve short-term abstinence. Our clinical and research observations
suggest that psychological factors including sleep-related performance anxiety, low
sleep-related self-efficacy and beliefs about needs for medications interact to lead to
difficulties abstaining from hypnotic use. Moreover, our highly promising pilot data suggest
that such factors may be mitigated by use of a blinded SMT protocol which appears to increase
rates of medication abstinence. The current project will use a 2 x 4 randomized longitudinal
clinical trial design to test the relative efficacy of our highly promising blinded tapering
protocol, vis a vis open-label tapering, when combined with therapist delivered CBT-I. A
sample of 260 will be enrolled, complete pre-intervention baseline measures and then be
randomly assigned to: (1) a blinded hypnotic SMT + therapist delivered CBT-I; or (2)
open-label tapering + CBT-I. During treatment all enrollees will first receive one on one
treatment sessions with a trained CBT-I therapist over a 6 week period while maintaining
baseline doses of their respective hypnotics. They then will begin a 10 week SMT during which
they are provided a blinded or open-label tapering SMT protocol. During this phase they will
have their hypnotic medication doses reduced by 25% every two weeks. Immediately after
completing the SMT and again at 3- and 6-month follow-ups they will complete study outcome
measures. The primary study outcome will be hypnotic discontinuance rates of the two
treatment groups. Secondary outcomes include nights of hypnotic use per week, nightly average
dosage of hypnotic used in diazepam equivalents as well as scores on sleep quality, daytime
fatigue and quality of life. This study will lead to refining guidelines for tapering methods
and providing a better understanding of treatment outcome predictors so as to provide more
successful, person-centered interventions.
