NCT03292146
This protocol is a randomized, double-blind, placebo-controlled clinical trial which aims to investigate the effect of denosumab on BMD in women with anorexia nervosa. The investigators hypothesize that 12 months of denosumab administration will result in an increase in bone mineral density, decrease in markers of bone resorption and improvement in bone microarchitecture in osteopenic women with anorexia nervosa compared with placebo. An optional extension study will offer subjects 12-month administration of open-label alendronate (an oral bisphosphonate) after the initial 12 month administration of denosumab or placebo. We hypothesize that 12 months of denosumab followed by 12 months of open-label alendronate will result in a greater increase in BMD compared to 12 months of placebo followed by 12 months of open-label alendronate. Within the group of women who receive sequential therapy with 12 months of denosumab followed by 12 months of alendronate, we hypothesize that BMD will be maintained between 12 and 24 months while on alendronate.
NCT05964413
A randomized, double-blind, placebo-controlled, multicenter, adaptive phase III trial to investigate efficacy and safety of vilobelimab in the treatment of ulcerative pyoderma gangrenosum
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.
NCT03648385
The goal of this crossover trial is to determine whether the study drug dehydroepiandrosterone (DHEA) improves right ventricular longitudinal strain measured by cardiac magnetic resonance imaging at 18 weeks AND 40 weeks compared to placebo and to assess side effects and safety in pulmonary arterial hypertension.
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.

NCT06333808
The goal of this clinical study is to learn more about the effects of switching to the study drugs, bictegravir (BIC)/lenacapavir (LEN), fixed-dose combination (FDC) versus current therapy bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) FDC in people living with HIV-1 (PWH). The primary objective of this study is to learn how effective it is to switch to BIC/LEN FDC tablets versus continuing on B/F/TAF FDC tablets in virologically suppressed PWH.
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.
