Active clinical trials for "Depressive Disorder"

A recent open label study of the effects of psilocybin in participants with treatment-resistant depression (TRD) showed rapid significant decrease of depressive symptoms after treatment with psilocybin coupled with psychological support. Over 40% of participants sustained response at 3 months. In this study, the aim is to explore effectiveness of 25 mg of psilocybin as an adjunctive therapy in participants with TRD.

This study evaluated the effectiveness and safety of improving depressive symptoms by applying tDCS for 6 weeks to patients with mild to moderate depression.

Multiple Dose Safety, Tolerability, PK and Food Effect Study of HEC113995 PA•H2O in Healthy Subjects

This study aims to evaluate the feasibility and effectiveness of a web-based self-help intervention in adolescents with acute or remitted major depressive disorder. We will examine whether this intervention improves positive affect, reduces stress and alleviates negative affect and depressive symptoms in adolescents aged 12 to 18 years. We will also investigate the rates of adherence among the adolescents who use this web-based intervention and the acceptability of the intervention with adolescents.

This is a randomized, double-blind, placebo-controlled clinical trial to evaluate the efficacy and safety of 10, 20, 40 and 60 mg oral PRAX-114 compared to placebo in the treatment of adults with MDD. The study will enroll participants on adjunctive treatment who had an inadequate response to their current antidepressant treatment and participants not currently being treated with pharmacotherapy for MDD. A sub-study to investigate the pharmacokinetics (PK) of PRAX-114 and metabolites when dosed in the evening in participants with MDD will be conducted in a subset of participants at selected research sites with serial PK sampling capabilities.

The purpose of this study is to collect biologically-based data for defining predictors and correlates of the effects of ALTO-300.

Despite the known efficacy of pharmacotherapy (i.e. antidepressants) and psychotherapeutic interventions in treating depressive disorders, research evidence suggests that 20% to 40% of patients with major depressive disorder (MDD) do not respond adequately to such treatments. These patients are diagnosed with Treatment-Resistant Depression (TRD), and are sometimes treated with convulsive therapy. However, about 10-30% of TRD patients do not respond to convulsive therapy, and are thus diagnosed with Ultra-Resistant Depression (URD). Using an open label pilot study involving subjects, this trial aims to assess the safety, tolerability, and clinical effects of intranasal ketamine (IN) treatment in patients who do not respond to convulsive therapy. Intranasal ketamine (IN) treatment approach has shown promising therapeutic outcomes for patients with TRD, but has not yet been studied on patients with URD.

The purpose of this study is to collect biologically-based data for defining predictors and correlates of the effects of ALTO-300.

First-line treatments for major depressive disorder (MDD), antidepressants and psychotherapy, are associated with refractoriness and discontinuation due to side effects, and logistical burdens, respectively. In this scenario, transcranial electrical stimulation (tES) is nowadays considered effective and safe for MDD, albeit with a modest effect size, and also prone to logistical burdens when performed in external facilities. In this regard, clinical investigation involving portable tES (ptES), and the potentiation of ptES with remotely-delivered psychological interventions, have shown positive, but preliminary, results. Here, the investigators present the design and rationale of a single-center, multi-arm, randomized, double-blind, sham-controlled clinical trial with digital features, using ptES (ptES) and internet-based behavioral therapy (iBT) for MDD (PSYLECT). This study will evaluate the efficacy, safety, tolerability and usability of (1) active ptES + active iBT ("double-active"), (2) active ptES + sham iBT ("ptES-only"), and (3) sham ptES + sham iBT ("double-sham"), in adults with MDD, with a Hamilton Depression Rating Scale - 17 item version (HDRS-17) score ≥ 17 at baseline, during 6 weeks. No antidepressant washouts will be performed during the trial. Three co-primary hypotheses are presented: changes in HDRS-17 will be greater in (1) "double-active" compared to "ptES-only", (2) "double-active" compared to "double-sham", and (3) "ptES-only" compared to "double-sham". The investigators aim to enroll 210 patients (70 per arm). The results of this trial should also offer new insights regarding the feasibility and scalability of combined ptES and iBT for MDD, in the area of digital mental health.

This multi-centre research investigates the effects of nature-based treatment group on participants diagnosed with depression. In total, 147 persons participated in the study in various locations in Finland. All participants received treatment as usual (TAU). They were randomised into nature-based group + TAU (n = 70) or TAU-only (n = 77). The participants in the nature-based group + TAU were offered 12 sessions once a week in addition to standard care. The measurement points included pre-treatment measurement at the baseline and post-treatment measurement at the end of the intervention, which was 12 weeks after the pre-treatment measurement. The follow-up measurement was 3 months after the post-treatment measurement. The effects of the intervention were assessed with a clinical measure of depression (BDI-I) and with indicators of psychological distress (CORE-10), subjective well-being (SWEMWBS), work/study ability (WAI) and nature experiences (ROS, KOLU). The participants in the treatment group (nature-based group +TAU) were compared to the participants in the control group who received TAU-only.
