NCT05776966
The goal of this study is to examine the feasibility of a gender-specific digital intervention for women with opioid use disorder. In this study, women with opioid use disorder will be randomized to receive treatment-as-usual plus a gender-specific digital intervention or treatment-as-usual only. Feasibility, satisfaction, and engagement with the intervention are the primary outcomes and will be measured post-intervention and at two-week, 6-week, and 12-week follow-up visits.

NCT02909192
Disruption of sleep and alertness is one of the most disabling non-motor symptoms of Parkinson's disease (PD). Mechanisms leading to impaired sleep and alertness in PD are not well understood, and treatment options remain limited. The proposed research will examine markers of the circadian system, sleepiness and sleep quality in PD patients. Further, the project will examine effects of bright light exposure on circadin function, sleep and alertness in PD.
NCT04245839
This is a global Phase 2, open-label, single-arm, multicohort, multicenter study to evaluate efficacy and safety of JCAR017 in adult subjects with r/r FL or MZL. The study will be conducted in compliance with the International Council on Harmonisation (ICH) of Technical Requirements for Registration of Pharmaceuticals for Human Use/Good Clinical Practice (GCP) and applicable regulatory requirements. This study is divided into three periods: * Pretreatment, which consists of screening assessments, leukapheresis and the Pretreatment evaluation; * Treatment, which starts with the administration of lymphodepleting (LD) chemotherapy and continues through JCAR017 administration at Day 1 with follow-up through Day 29; * Posttreatment, which includes follow-up assessments for disease status and safety for 5 years.
NCT06479187
The goal of this clinical trial is to learn if serial PSMA-PET/CT scans can be used to monitor response to therapy in metastatic hormone sensitive prostate cancer and can be potentially used to optimize future treatment approaches. The main questions it aims to answer are: What is the proportion of men with residual PSMA-avid disease on PET/CT scans after 6 months of treatment for metastatic hormone sensitive prostate cancer? Do the findings on PSMA-PET/CT scans after 6 months of treatment for metastatic hormone sensitive prostate cancer correlate with other markers of disease status, like PSA? Participants will: Receive standard of care treatment for metastatic hormone sensitive prostate cancer Undergo a PSMA-PET/CT scan before starting treatment Undergo a PSMA-PET/CT scan after 6 months of treatment Have a chart review every 3 months for 1 year after the 6 month PSMA-PET/CT scan
NCT07079761
Purpose: About 6.4% of the U.S. population suffers from posttraumatic stress disorder (PTSD). Trauma-focused psychotherapies are generally effective in PTSD, but responses vary greatly across individuals and PTSD subpopulations. Neurobiological factors impacted by life experiences, stress, and genetics can affect treatment responses. These factors can alter brain capacities needed to reprocess traumatic memories prevent them from triggering intensely distressing, disruptive, out-of-place responses. For example, during psychotherapy for PTSD, trauma memory activation engages two competing brain processes that affect recovery: "extinction" versus "reconsolidation" of trauma-related emotional, physiological, and behavioral responses. This study tests whether a single intravenous (IV) dose of allopregnanolone (Allo) compared to placebo (which is non-active): promotes consolidation of extinction learning (sub-study 1) or blocks reconsolidation of physiological responses triggered by aversive memories (sub-study 2). The study also tests whether Allo compared to placebo affects retention of non-aversive memories.
NCT03716830
In this study, investigators will examine the brain mechanism behind the synergistic effects of combining acupuncture and transcranial direct current stimulation (tDCS) treatments. Specifically, chronic low back pain (cLBP) patients will be recruited and randomized to one of four groups (30 per group, one month of treatment): 1) verum acupuncture + real tDCS, 2) sham acupuncture + real tDCS, 3) verum acupuncture + sham tDCS, and 4) sham acupuncture + sham tDCS. Investigators will study 1) the longitudinal (one-month) effects of different treatments as indicated by changes in resting state functional connectivity (rsFC), cerebral blood flow (CBF), clinical outcomes of low back pain, and quantitative sensory test (QST) and 2) the association between these changes.
NCT06203717
The goal of this study is to test whether active duty firefighters find it possible and suitable to do cranial electrotherapy stimulation (CES) at home, and test whether CES influences measures of depression and posttraumatic stress. The main questions it aims to answer are: * is CES feasible and acceptable in a population of firefighters, and * does CES changes feelings of depression, anxiety, and fatigue in firefighters. Participants will * complete four weeks of CES at home, and * complete daily assessments of affect and fatigue, and * complete self-reported symptoms of depression and posttraumatic stress before and after four weeks of CES at home Participants maybe asked to * complete an MRI scan before and after four weeks of CES at, and * wear a device to measure their heart rate and sleep quality.
NCT05585775
The primary objective for this project is to test whether affective executive functioning is a mechanism of action of mindfulness-based cognitive therapy and Wellness for Wellbeing. The main questions it aims to answer are: 1. Test the effect of MBCT vs. Wellness for Wellbeing on affective inhibition (i.e., emotionally valenced inhibition as measured via the affective Go/No Go task) using an RCT. 2. Test the effect of MBCT vs. Wellness for Wellbeing on (a) affective updating and (b) affective shifting. Outcomes will be measured with the affective n-Back and the affective Internal Switching Task, respectively. 3a) The investigators will examine whether depression symptom severity co-varies with change in affective executive functioning (i.e., affecting inhibition, shifting, and updating) over time. 3b) The investigators will examine whether compliance with treatment protocol (e.g., number of classes attended, amount of home practice) predicts endpoint executive functioning. Participants will complete surveys, interviews, and computer tasks, and will be randomized to either Mindfulness-Based Cognitive Therapy or Wellness for Wellbeing.

NCT04968912
The purpose of this study is to evaluate the efficacy and safety of nipocalimab in participants with primary Sjogren's syndrome (pSS) versus placebo.
NCT05819398
This study is open to adults with moderate to severe hidradenitis suppurativa (HS). The purpose of this study is to find out whether a medicine called spesolimab helps people with HS. People who have previously taken specific medicines such as immunosuppressive biologics other than Tumor necrosis factor (TNF) inhibitors cannot take part. This study has 2 parts. In Part 1, participants are divided into 4 groups of almost equal size. 3 groups get different doses of spesolimab, 1 group gets placebo. All participants get injections into a vein or under the skin. Placebo injections look like spesolimab injections, but do not contain any medicine. Every participant has an equal chance of being in each group. In the beginning, participants get the study medicine every week and later every 2 weeks. After 4 months, participants in the placebo group switch to spesolimab treatment. In Part 2, participants are divided into 2 groups. One group gets a suitable dose of spesolimab that was found in Part 1 of the study. The other group gets placebo. After 4 months, participants in the placebo group switch to spesolimab treatment. Participants join only one of the two parts. They are in the study for about 1 year. During this time, they visit the study site in the beginning every week and later every 2 weeks. Some of the visits can be done at the participant's home instead of the study site. The doctors regularly check participants' HS symptoms. The results are compared between the groups to see whether spesolimab works. The doctors also regularly check participants' general health and take note of any unwanted effects.
