Pilot Study: Establishing Glutamatergic Changes in Rapid Antidepressant Effects of Ketamine
Testing how ketamine changes brain chemicals in people with depression
📍 University of Pennsylvania · Philadelphia, PA · Get directions →
In the treatment of Major Depressive Disorder (MDD), ketamine can produce rapid but short-lasting improvements in mood. In order to develop a new generation of treatments with rapid and sustained efficacy, a better understanding of the mechanism of action is urgently needed.

Integrating Inuit Knowledge Principles in Multi-Level Mental Health Clinical Trials
Testing whether eating more country foods and cultural activities help Inuit adults with depression
📍 Aqqiumavvik Society · Arviat, Nunavut · Get directions →
This study is looking at how eating more country foods affects mental health among Inuit men and women in Arviat, NU. The goal is to evaluate if eating more of these foods helps people feel less depressed or anxious, and whether being part of food-gathering and cultural activities also makes a difference.
- Crohn's / ulcerative colitis (IBD)
Effect of Statins on Crohn's Disease
Testing whether statins can reduce gut narrowing (strictures) in adults with Crohn’s disease
📍 Stanford University · Stanford, CA · Get directions →
The goal of this clinical trial is to learn if statins work to prevent strictures in adults with Crohn's disease. The main question it aims to answer is: * Can statins reduce the formation of strictures in participants with stricturing Crohn's disease?
- Crohn's / ulcerative colitis (IBD)
Cranberry and Gut Health in Crohn's Disease
Testing whether a cranberry supplement helps gut health in people with Crohn’s disease
📍 UMASS medical center · Worcester, MA · Get directions →
This study is investigating whether a cranberry-based dietary supplement, rich in polyphenols and fiber, can enhance gut health in individuals with Crohn's disease. People with Crohn's disease often have an imbalance in their gut microbiome (the community of bacteria in the gut).
- Kidney disease
Concomitant Renal and Urinary Bladder Allograft Transplantation
Testing whether transplanting a new kidney and bladder at the same time is possible for people with
📍 Mayo Clinic · Rochester, MN · +1 more US site · Get directions →
The purpose of this study is to establish if concomitant renal and vascularized urinary bladder allograft transplantation is feasible.
- Depression
Probiotic Administration for Adolescent Depression
Testing whether a probiotic affects brain and gut in teens with depression
📍 UCSF · San Francisco, CA · Get directions →
This double-blind, placebo-controlled clinical trial will examine the effect of probiotic Visbiome on the brain and gut microbiome of individuals 15 to 24 years of age.
- Kidney disease
Feasibility Trial of Sodium-GLucose coTransporter 2 INhibitors in Pediatric Chronic KIDney DiSease
Testing whether a trial of SGLT2 inhibitors in youth with chronic kidney disease is feasible
📍 Ann & Robert H. Lurie Children's Hospital of Chicago · Chicago, IL · Get directions →
The goal of this study is to learn if a clinical trial of sodium-glucose co-transporter 2 inhibitors (SGLT2i) is possible in youth with chronic kidney disease (CKD). The investigators also plan to explore whether treatment with SGLT2i (Empagliflozin) helps improve risk factors for worsening kidney and heart disease.
- Depression
A Randomized Pilot rTMS Trial for Knee Arthritis Pain and Depression
Testing a brain stimulation treatment to help knee arthritis pain and depression
📍 UCLA Semel Institute - Neuropsychiatric Institute (NPI) · Los Angeles, CA · Get directions →
Osteoarthritis (OA) is a major public health problem, and involvement of the knee is especially disabling. Symptomatic knee OA has an incidence rate between 40 to 1,020 per 100,000 person years1 and is among the most common causes of disability worldwide.
- Type 2 diabetesKidney disease
Subclinical Primary Aldosteronism in Diabetes At-Risk for Kidney Disease
Testing whether people with type 2 diabetes have early hormone-related kidney risk
📍 Brigham and Women's Hospital · Boston, MA · Get directions →
The aim of this protocol is to assess the presence and severity of primary aldosteronism pathophysiology in patients with type 2 diabetes who have, or are at-risk for developing, chronic kidney disease.
- Depression
Confirmatory Efficacy Trial of Attention Bias Modification for Depression
Testing two types of attention-bias training for adults with depression
📍 Institute for Mental Health Research · Austin, TX · Get directions →
The goal of this clinical trial is to compare the efficacy of two related, but different ABM (Attention Biased Modification) treatments for depression in adults with elevated symptoms of depression. The main aims are: * Aim 1:examine whether gamified ABM leads to greater change in the primary and secondary outcomes than sham ABM * Aim 1: establish that gamified ABM is at least as effective as traditional ABM.
- Depression
Mood Effects of Serotonin Agonists: Depression
Testing how a low dose of LSD affects mood in people with depression
📍 University of Chicago · Chicago, IL · Get directions →
This study will examine the effect of a low dose of the 5HT2A agonist LSD (26 µg), compared to placebo, on acute and protracted mood states in individuals with depression. The investigators will assess the relationship between mood-related symptoms and EEG as a neurophysiological marker.
- Sickle cell disease
