Active clinical trials for "Stress Disorders, Traumatic"

This is a Phase 2 randomized, double-blinded, placebo-controlled study that will evaluate multiple potential pharmacotherapeutic interventions for PTSD utilizing an adaptive platform trial design. Intervention C - Daridorexant will assess the safety and efficacy of daridorexant in participants with PTSD. Please see NCT05422612 for information on the S-21-02 Master Protocol.

The aim of the present study is to assess the availability of cannabinoid receptors (CB1R) in the human brain. CB1R are present in everyone's brain, regardless of whether or not someone has used cannabis. The investigators will image brain cannabinoid receptors using Positron Emission Tomography (PET) imaging and the radioligand OMAR, in healthy individuals and several conditions including 1) cannabis use disorders, 2) psychotic disorders, 3) prodrome of psychotic illness and 4) individuals with a family history of alcoholism, 5) Post-Traumatic Stress Disorder 6) Opioid Use Disorder using the PET imaging agent or radiotracer, [11C]OMAR. This will allow us to characterize the number and distribution of CB1R in these conditions. It is likely that the list of conditions will be expanded after the collection of pilot data and as new data on cannabinoids receptor function and psychiatric disorders becomes available. Those in the cannabis us disorder arm of the study will have a PET scan on at least three occasions: once while smoking as usual, once after 48-hours of abstinence from cannabis, and a final time after 4 weeks of abstinence. Additional scans may be conducted within the 4 weeks and the last scan may be conducted well beyond 4 weeks. Similarly, while most schizophrenia patients may get scanned just once, a subgroup of patients may get scanned more than once. For example to tease out the effects of medications, unmedicated patients may get scanned while unmedicated and again after treatment with antipsychotic medications. Similarly prodromes may get scanned while in the prodromal stage off medications, on medications and after conversion to schizophrenia.

This is a multiwave longitudinal neuroimaging study in a cohort of direct survivors of 11/13 Paris terrorist attacks. Both structural and functional brain imaging data will be collected at 8-12 months, 3 years, and 6 years after trauma in exposed participants as well as in control non-exposed participants. This project will capitalize on recent evidence showing that healthy participants can prevent unwanted images from entering consciousness using inhibitory control and memory suppression techniques, disrupting traces of the memories in sensory areas of the brain, and weakening their vividness and later reentrance. This process is believed to be affected in Post-traumatic stress disorder (PTSD) which is characterized by anxiety and persistent intrusive memory of the traumatic event with highly distressing contents. This project will thus provide a unique opportunity to observe the online and structural dysfunctions of intrusion control network following a severe psychological trauma and how such process may contribute to recovery and psychopathological dynamics. In addition, the disruption of social cognition and emotional processing following PTSD will also be investigated in relation to disrupted inhibitory control functioning.

This study will examine context sensitivity, composed of two sequential elements: (a) accurate classification of changing affective contextual demands, followed by (b) flexible selection of regulatory strategies that matches changing contextual demands, among complex PTSD vs. Healthy controls.

This is a Phase 2 randomized, double-blinded, placebo-controlled study that will evaluate multiple potential pharmacotherapeutic interventions for PTSD utilizing an adaptive platform trial design. Intervention A - Fluoxetine will assess the safety and efficacy of fluoxetine in participants with PTSD. Please see NCT05422612 for information on the S-21-02 Master Protocol.

This is a Phase 2 randomized, double-blinded, placebo-controlled study that will evaluate multiple potential pharmacotherapeutic interventions for PTSD utilizing an adaptive platform trial design. Intervention B - Vilazodone will assess the safety and efficacy of vilzodone in participants with PTSD. Please see NCT05422612 for information on the S-21-02 Master Protocol.

The study investigators are conducting the first open label pilot trial of MDMA-assisted therapy (MDMA-AT) with a comorbid sample of military veterans with a comorbid diagnosis of Alcohol Use Disorder (AUD) and Post-Traumatic Stress Disorder (PTSD). This novel experimental treatment package consists of two once-monthly Experimental Sessions of therapy combined with a divided-dose of MDMA HCl, along with non-drug preparatory and integrative therapy. The Primary Outcome measure, the Timeline Follow-back (TLFB), will evaluate changes in alcohol use over time. Changes in PTSD symptoms will also be evaluated.

The aim of this study is to demonstrate the effectiveness of propranolol in blocking reconsolidation by reducing PTSD symptoms in the short and long term in adolescents with PTSD for more than 3 months.

Recent data suggest that the cannabinoid-system is involved in stress regulation and posttraumatic stress disorder (PTSD). Low endocannabinoid signaling has been found in PTSD patients and might even present a precondition to develop PTSD after trauma. The aim of the current project is to investigate the impact of an activation of the cannabinoid system with an exogenous cannabinoid (dronabinol, i.e., delta-9-tetrahydrocannabinol) on fear conditioning.

The overall objective of this study is to use standard clinical measures to explore the safety and preliminary effectiveness of open-label MDMA-assisted therapy with a flexible dose of methylenedioxymethamphetaminel, in participants with Post traumatic Stress Disorder and moral injury, in individual and group treatment settings. The overall safety objective is to assess the severity, incidence, and frequency of AEs, AEs of Special Interest (AESIs), and Serious Adverse Events (SAEs), concomitant medication use, suicidal ideation and behavior and vital signs .
