NCT ID: NCT03874611 Recruiting - Depression Clinical Trials

Electrophysiology of Brain Activity During Electrode Implantation in Patients Treated With Deep Brain Stimulation

LFP-DBS
Start date: April 13, 2011
Phase: N/A
Study type: Interventional

Primary objective Demonstrate functional markers derived from electrophysiological signals recorded during cognitive tests. These markers should make it possible to optimize the targeting procedures of electrode implantation sites for a better effectiveness of deep brain stimulation therapy. Research hypotheses The mechanisms of action of the deep brain stimulation (DBS) involve the modulation of the activity, locally and on a large scale, of functional cortical-subcortical networks showing pathological behavior beforehand. The electrophysiological measurements in response to different tasks make it possible to highlight precise dysfunctions of these neural networks, in relation with the behavioral and / or motor disorders associated with the pathologies treated by DBS. Consequently, we hypothesize that the exploitation of electrophysiological responses during cognitive or sensorimotor tasks performed during the implantation procedure of stimulation electrodes in patients treated with DBS will allow : - To collect fundamental data to understanding the physiological functioning of basal ganglia in humans ; - To collect functional markers from the operating room in relation to the symptoms targeted by the DBS that will help in the choice of implantation site of the stimulation electrode ; - Define long-term predictive markers of DBS effects by comparing electrophysiological effects measured post-operatively and clinical scores under DBS.

NCT ID: NCT03874130 Recruiting - Clinical trials for Major Depressive Disorder (MDD)

Scopolamine in Healthy Volunteers

Start date: August 1, 2018
Phase: Phase 1
Study type: Interventional

This single-site clinical trial is an open-label study to identify the safety and pharmacokinetics of DPI-386 Nasal Gel (intranasal scopolamine gel) and IV Scopolamine. The study will require subjects to receive either multiple doses of 0.2 mg or a single dose of 0.4 mg, 0.6 mg, 0.8 mg, 1.0 mg, or 1.2 mg of DPI-386 Nasal Gel or 0.4 mg/mL IV Scopolamine per the assigned treatment cohort. Multiple PK blood draws will be collected dependent on cohort assignment. Vital signs and ECGs will be collected. No efficacy will be tested. Subjects will be monitored for at least eight hours after the final dose. There could be up to 120 subjects enrolled stratified equally by gender. Screening will not occur until after subjects have signed the informed consent form (ICF). Screening will include hematology, biochemistry, urinalysis, alcohol and drug screen, physical examination, including vital signs and ECG, and review of medical history by the PI or qualified designee, serum pregnancy test as applicable, and agreement to adhere to the study lifestyle requirements. Subject data will be recorded in the source documents and appropriate eCRF.

Major Depressive Disorder: Early Prediction of Non-response to Antidepressant Therapy Via a Mobile Digital Scale

REDRESS
Start date: May 2019
Phase: N/A
Study type: Interventional

Major Depressive Disorder (MDD) is a debilitating disease characterized by a depressed mood, diminished interests, impaired cognitive function and vegetative symptoms, such as disturbed sleep or appetite. MDD occurs about twice as often in women than it does in men and affects about 6% of the adult population worldwide each year. Standard symptoms scales like the Hamilton Depression Rating Scale or the Montgomery-asberg Depression Rating Scale, the Self-Report 16-item Quick Inventory of Depressive Symptomatology were initially developed for the evaluation of a therapeutic intervention or a pharmacological treatment and are routinely used by clinicians in the assessment of Treatment Resistant Depression (TRD) occurrence. In parallel, patient-reported outcomes have gained increasing importance and are widely recommended by health authorities in the assessment of depression. The same institutions insist on the collection of real-world data to provide clinicians with ecological measurements. It has been demonstrated that an early response to an AntiDepressant (AD) treatment can be seen as early as week 2 and is not related to a placebo-effect. While there is no consensus on the exact cut-off values, several factors emerge as early predictors of a later treatment response, such as: - Improvement in emotional processing of happy facial expressions after 1 week of treatment, - Circa 20% improvement in Hamilton Depression Rating Scale-17 item (HDRS-17) at week 2. The hypothesis is therefore that repeated, systematic and real-time, contextualized and multimodal collection of depressive symptoms from patients at home will establish a threshold score that can predict a subsequent response to their treatment. REDRESS was inspired by several standard depression scales used and recommended by the French Health Authority, augmented with digital active and passive activity monitoring, speech analysis and emotional processing assessment. Another important assumption is that honesty and willingness to disclose personal or embarrassing things will be best achievable via a digital solution. To test this assumption, the overall scores and each subscores on the REDRESS numerical scale will be compared in people with MDD showing adequate response to those showing insufficient response. The response to treatment at week 6 will be studied (end of Phase 1). Non-responders and responders to the first treatment round will be enrolled in a 6-week extension phase (Phase 2). Non-responders will receive another treatment course (Other AD, combination, etc.). Responders will just be followed up and will keep the same treatment. The REDRESS scores will be analysed in this population and will allow us to test the investigator's assumption in people with treatment resistant depression. This study will also allow to assess patients' quality of life at the end of each phase of treatment and to compare results with REDRESS scores.

NCT ID: NCT03871842 Recruiting - Depressive Symptoms Clinical Trials

Effects of tDCS on Depressive Symptoms of Participants With Temporal Lobe Epilepsy

Start date: July 1, 2018
Phase: N/A
Study type: Interventional

This project was developed to analyze the clinical, biochemical and functional impact of tDCS on depressive symptoms in participants with temporal lobe epilepsy, intending to collaborate directly in the development of new therapeutic strategies for participants with epilepsy and associated mood disorders. Another objective of this work is to add knowledge about biosafety, possible behavioral and electrophysiological effects of tDCS in participants with temporal lobe epilepsy. Depending on the findings, the study as proposed may provide immediate results for the care of participants with epilepsy.

NCT ID: NCT03869736 Recruiting - Depression Clinical Trials

Nitrous Oxide for the Treatment of Major Depressive Disorder

Start date: January 22, 2019
Phase: Phase 2
Study type: Interventional

The investigators are conducting a randomized controlled trial to evaluate the antidepressant effects of nitrous oxide in people with Major Depressive Disorder (MDD). MDD is a global medical condition that causes significant health and economic burden. Recent studies have shown that a single dose of ketamine, an NMDA-antagonist, has fast and long lasting anti-depressant effect. Nitrous oxide, another NMDA-antagonist, is widely used for anesthesia and analgesia, safer to administer and has fewer side effects than ketamine. A randomized controlled crossover feasibility study showed significant reduction in depressive symptoms at 2 and 24 hours after a single 1-hour treatment session of inhaled nitrous oxide compared with placebo. Nitrous oxide is inexpensive and can be safely administered by any trained clinician. If found to be efficacious, it could be used to provide rapid anti-depressant effect whilst the benefit of traditional anti-depressants has its delayed effect. Another potential application could be in acutely suicidal patients. This investigated-initiated phase 2b trial will enable confirmation and extension of the findings from the feasibility study, and identify the optimal dose and regimen in a broader population of those with MDD. Participants will be randomized to receive a weekly 1-hour inhalational sessions of either nitrous oxide or placebo (oxygen-air mixture) for 4 weeks, and the nitrous group will be further randomly assigned to a dose of 50% nitrous oxide or 25% nitrous oxide. Depression severity will be assessed by a blinded observer pre-treatment and at weekly intervals during and for 4 weeks after treatment using the Hamilton Depression Rating Scale.
