Active clinical trials for "Depressive Disorder, Treatment-Resistant"

This study evaluates an association between brain-derived neurotrophic factor(BDNF) polymorphisms and the antidepressant efficacy of transcranial magnetic stimulation device in patients with treatment-resistant depression. In a double-blind design, All patients are randomized to three groups, i.e.repetitive transcranial magnetic stimulation treatment, intermittent theta-burst stimulation treatment or sham treatment.

LQD is a multicentre randomised clinical trial comparing the clinical and cost effectiveness of lithium versus quetiapine when used as add-on therapies to antidepressant medication for patients with treatment resistant depression. The Lithium versus Quetiapine in Depression (LQD) study will assess patients over 12 months to establish which (if any) treatment is more likely to improve TRD over a long duration of time. Professor Anthony Cleare is the Chief Investigator and recruitment began in November 2016.

This study investigates the brain-based biomarkers of treatment response to accelerated theta burst stimulation (aTBS) in patients with Major Depressive Disorder resistant to pharmacological treatment(MDD) in an open label design.

This is a two-stage experiment; the first stage is an open label trial in which participants receive six intravenous (IV) treatments of ketamine. The second stage includes participants that responded to ketamine (i.e. reduction of 25% in their symptoms of depression, as measured by the Montgomery Asberg Depression Scale MADRS). The second stage is a double-blind, controlled clinical trial of D-cycloserine (DCS) vs. placebo, as maintenance treatment in patients who responded to ketamine treatment. The aim of the study is to determine whether 8 weeks of DCS maintenance therapy will prevent relapse of depressive symptoms following ketamine infusions

The purpose of this study is to determine whether an oxytocin ad-on, or oxytocin and tibolone ad-on can induce a response to antidepressants in patients with treatment resistant depression.

This is a randomized, placebo-controlled double-blind cross-over trial evaluating the safety, efficacy, daily functioning, and health-related quality of life of Subcallosal Cingulate Gyrus Deep Brain Stimulation (SCG DBS) for participants with Treatment-Resistant Depression (TRD). A total of 40 eligible participants will be randomized to four treatment sequences (10 participants per sequence). Each participant will be treated over a 6-month period with active or sham stimulation in which both the participants and the attending psychiatrists will be blinded to treatment allocation.

The habenula (Hb) is an ancient structure, located at the center of the dorsal diencephalic conduction system, a pathway involved in linking forebrain to midbrain regions. An increasing number of studies indicated that the lateral habeluna (LHb) is overactivity during depressive behaviors in rats, where it could drive the changes in midbrain monoamine neurotransmitter linked to depression. However, the efficiency and mechanism of deep brain stimulation (DBS) of the LHb and/or its major afferent bundle (i.e., stria medullaris thalami) could treat treatment-resistant major depression (TRD) is still unclear. This research will investigate the effectiveness and mechanism of bilateral MRI Compatible and Long-term LFP Recordable DBS to habenula and/or its major afferent bundle for treatment TRD patients.

Study of individualized accurate targeting rTMS intervention on motivational anhedonia of treatment resistant depression and brain network mechanism

This is a pilot interventional study to investigate the acceptability, tolerability, and side effect profile for varying numbers of treatment sessions/day of a new rTMS treatment in adolescents with treatment-resistant depression (TRD). Conventional rTMS has been limited to sinusoidal biphasic electromagnetic pulses. In contrast, the First Dawn rTMS system by NeuroQore can sustain a repetitive linear asymmetric pulse. In addition, identification of rTMS treatment sites in adolescents with TRD most often relies on anatomic landmarks, but the First Dawn rTMS system utilizes personal fMRI data in a novel algorithm to determine where to apply the rTMS in each patient. Based on adult data in healthy volunteers and patients with TRD, the investigators propose that the First Dawn rTMS system will be acceptable and well-tolerated by adolescents and will have minimal side effects. Please see https://clinicaltrials.gov/ct2/show/NCT02667041 for details on the completed pilot study in adults. The investigators aim to investigate acceptability, tolerability, and side effects in groups of patients receiving treatment in numbers of sessions/day that are gradually accelerated over the course of the study. Results will be used to inform the development of a randomized controlled trial.

The TARGET study is an active-controlled evaluation of AXS-05 compared to bupropion in patients with treatment-resistant major depressive disorder (MDD) who are adherent to study drug. Subjects are considered to have treatment-resistant MDD if they have had a historical inadequate response to 1 or 2 prior antidepressant treatments (ADTs) and a prospective inadequate response to treatment with bupropion SR, during the current major depressive episode. The TARGET study will first determine treatment adherence based on analysis of drug concentrations of dextromethorphan (in the AXS-05 group) and bupropion (in the bupropion group), and then evaluate the efficacy of AXS-05 in patients determined to be treatment-adherent. Efficacy data for evaluation of treatment effect will be obtained from assessments made during study AXS-05-301.
