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

The Canadian Rapid Treatment Center of Excellence (CRTCE) is a healthcare facility principally focused on providing best practices of intravenous ketamine treatment to adult patients suffering from treatment resistant depression. Patients who have received IV ketamine at the clinic are eligible to participate in this study where genetic biomarkers are correlated with response to IV ketamine.

This observational study will allow data to be collected to demonstrate changes in brain activity following administration of standard of care (SOC) Ketamine. By comparing genetic markers across participants, data on impact of genetic markers and response to Ketamine will also be analysed. This data will contribute to the design of future studies utilizing Ketamine for various psychiatric disorders. This study will focus on treatment-resistant Major Depressive Disorder (MDD).

Treatment resistant depression (TRD) is a major health concern, with 10% of patients with major depressive disorder not responding to conventional treatments. The investigators propose to compare the MRI (magnetic resonance imaging) brain scans of patients with TRD, which were collected during surgical planning for deep brain stimulation, with age, sex, handedness and education-matched healthy volunteer controls, to investigate anatomical differences, specifically the volume of certain brain structures.

The purpose of this study is to assess the participants socio-demographics and disease-related characteristics, long-term naturalistic treatment patterns and the clinical, social and economic outcomes of routine clinical practice in the treatment of participants with treatment-resistant depression (TRD) in a variety of European countries.

In this observational, non-invasive clinical study different neurobiological analyses will be performed in a group of patients with severe treatment resistant major depression participating in an efficacy study of deep brain stimulation of the superolateral branch of the medial forebrain bundle (slMFB) - FORESEE III.

This is a pre-approval access program (PAAP) for eligible participants. The main purpose of this program is to provide access to esketamine nasal spray to eligible participant with treatment-resistant depression (TRD), who have exhausted all other treatment options, including all alternative treatment options with marketed therapies.
