Clinical Trial Summary
This is a randomized clinical trial to test the effectiveness of combining a proven
psychological intervention called behavioural activation therapy alongside esketamine
treatment for treatment resistant major depressive episodes in individuals with major
depressive disorder or bipolar disorder. Encouraging participants to practice new behaviours
while their mood is improved through esketamine treatment may lead to more lasting recovery
from depression.
Description:
Depression is the leading cause of disability in the world and current treatments with
medication are limited. Over one-third of individuals with major depressive disorder (MDD)
and one quarter of individuals with bipolar disorder (BD) do not benefit from traditional
pharmacotherapies, leading to treatment-resistant depressive episodes. Individuals with
treatment-resistant depressive episodes (defined as a suboptimal response to two or more
appropriate trials of antidepressant medication) have a higher burden of illness, higher
healthcare utilization, poorer quality of life, worse occupational and social outcomes, and
are at greater risk of death. Treatment-resistance may increase an individual's likelihood of
engaging in suicidal behaviours and an estimated 30 percent of individuals with
treatment-resistant depressive episodes will have a suicide attempt in their lifetime. To
address these gaps in treatment, there has been growing interest in the use of intravenous
(IV) ketamine as well as its newly marketed stereoisomer, esketamine, which is delivered
intranasally.
The discovery of the rapid antidepressant effects of low doses of ketamine has been hailed as
a paradigm shift in psychiatry. However, a remaining challenge to address is the temporary
nature of its effects. Ketamine induces neuroplasticity-enhancing effects more than
conventional medications for depression. There may be the potential to harness this window of
neuroplasticity to facilitate more lasting cognitive and/or behavioural changes through
psychotherapy. To date, there are no randomized clinical trials of combined treatment with
esketamine and psychotherapy for treatment-resistant depressive episodes. Studies to ensure
that individuals can maximally benefit from this novel treatment are needed.
The overall goal of this project is to maximize and sustain the beneficial effects of
esketamine through combined treatment with behavioural activation (BA) therapy. The central
hypothesis is that combined esketamine and BA therapy will elicit larger and faster decrease
in depressive symptoms and more improvement in functional recovery compared with esketamine
treatment alone.
The specific aims of this research study are as follows:
Aim 1. To determine if there is a larger decrease in depressive symptoms in participants
receiving BA concurrent with esketamine treatment compared to participants receiving
esketamine alone.
Aim 2. To compare the speed of antidepressant response in participants receiving BA
concurrent with esketamine treatment compared to participants receiving esketamine alone.
Aim 3. To assess if participants receiving BA concurrent with esketamine treatment perceive
greater improvement in functioning (self-reported depressive symptoms, quality of life,
anhedonia, hopelessness, and work and social functioning) compared to participants receiving
esketamine alone.
This study is a single-site, parallel-arm, randomized clinical trial investigating the
effects of augmenting esketamine treatment with BA therapy, an empirically supported
treatment for depression.
Participants will be randomized to one of two groups: 1) concurrent esketamine and BA therapy
started from treatment initiation, or 2) esketamine treatment alone.
Esketamine treatment will be offered as treatment as usual. All study participants will be
offered a 12 session course of BA therapy, half will be randomized to receive BA concurrently
with their esketamine treatment from initiation. Participants randomized to the esketamine
treatment alone arm will be offered a full course of BA sessions after week 12 during the
maintenance phase of treatment or at the time esketamine treatment ceases, whichever is
earlier.
BA therapy will be delivered virtually or in person according to participant preference (mode
of administration will be recorded and included in data analysis as appropriate). The aim of
BA therapy is to help individuals learn to observe the relationship between what they did,
felt, and thought and what was happening around them, and to identify conditions which
maintained, increased, or weakened maladaptive behaviours. Functional behaviour analysis will
be used in problem and behaviour evaluation and in planning and reviewing changes introduced
by participants between sessions. Other techniques include self-observation and self-report,
elaboration of activity hierarchies, behaviour programming, rehearsal and behavioural
modelling, and contingency management. Between-session homework will develop relevant and
rewarding day-to-day routines liable to offer reinforcement in each participant's
environment. An independent expert will assess the quality and adherence to BA for the trial.
This will be the first clinical trial to test the concurrent use of esketamine and a
behavioural intervention. The efficacy data for esketamine largely comes from randomized
controlled trials and thus may not always reflect the clinical reality for individuals who
present for treatment in hospital settings. Conducting research with esketamine in a
naturalistic academic-hospital setting will inform clinical practice. The goal is to offer
esketamine to individuals as part of a comprehensive treatment plan to help them achieve
longer-term recovery as opposed to short-lived decrease in clinical symptoms.
