NCT05551702
The purpose of the research study is to investigate whether CBT-txt, a counseling program delivered by text messages is effective in stopping or reducing depressive symptoms. CBT-txt is based on a counseling program that has been proven to reduce depression when delivered in-person and on the web, but has not yet been tested or shown to be effective when delivered by text.
NCT06410599
To enroll in this clinical trial, prospective participants must meet stringent criteria. The participants need to fall within the age range of 18 to 64 and exhibit chronic depression at therapy resistance stage 2. This stage signifies that the participants have undergone unsuccessful treatment with at least two different antidepressants, despite adequate dosage and duration. Moreover, the participants should have engaged in at least 12 sessions of psychotherapy without experiencing significant relief from depressive symptoms. Additionally, participants must demonstrate the cognitive capacity to provide informed consent. Upon expressing interest in the study and consenting to participate, individuals undergo a thorough screening process. This screening encompasses a comprehensive clinical interview to assess medical and psychiatric history, as well as various medical tests. These tests include physical examinations, blood draws (which may include pregnancy tests for female participants), and electrocardiograms (ECGs) to evaluate heart function. Following the screening, participants are randomly assigned to one of three different treatment groups (Ketamine +TAU; Ketamine+CBASP, Placebo+CBASP). The study protocol involves a combination of psychotherapeutic treatment and either ketamine infusions or placebo. Throughout the study period, participants are subject to regular data collection, including psychological assessments, blood samples, and magnetic resonance imaging (MRI) scans. Participants' responses to treatment, as well as any changes in symptoms or side effects, are closely monitored. After completing the study, participants are offered follow-up therapy as part of standard care. MRI scans are conducted to examine changes in brain activity associated with treatment response and depressive symptomatology, particularly focusing on alterations in neural circuitry and thought processes. Additionally, participants are encouraged to report any changes in medication regimen or other treatments received during the study period.
