- COPD (chronic lung disease)
Genetic Variation in IgG in Alpha 1 Antitrypsin Deficiency
Testing how a genetic change in alpha-1 antitrypsin affects immune and lung responses to a pneumonia
📍 University of Alabama at Birmingham · Birmingham, AL · Get directions →
The goal of this study is to learn whether patients who have a genetic mutation in the genes that cause alpha 1 antitrypsin deficiency also have genetic variation in nearby genes that can increase risk for reduced immune function and respiratory infections. To investigate this hypothesis, we will compare immune responses to the 20-valent pneumococcal conjugate vaccine (PCV20, Pfizer) between participants who have one abnormal copy of the SERPINA1 gene and either no COPD exacerbations, vs those with 2 or more COPD exacerbations in the past year.
- COPD (chronic lung disease)Asthma
The Effects of Positive Airway Pressure on the Mucolytic Effects of NAC (TEAM)
Testing whether positive airway pressure helps a lung medicine (NAC) reach mucus plugs in asthma or
📍 UCSF Airway Clinical Research Center · San Francisco, CA · Get directions →
The goal of this clinical trial is to determine if positive pressure during inspiration will improve penetration of aerosolized N-Acetylcysteine (NAC) into airway mucus plugs in the lungs of patients with asthma or Chronic Obstructive Pulmonary Disease (COPD). The main questions it aims to answer are: * Does delivery of aerosolized NAC with positive inspiratory pressure have a greater effect on mucus plug burden in the lungs than delivery of NAC without positive pressure.

Impact GLP-1 Agonists Following Bariatric
Testing whether GLP-1 medicines after bariatric surgery affect weight and blood sugar
📍 University of Missouri Hospital · Columbia, MO · Get directions →
Glucagon-like peptide 1 (GLP-1) is a hormone that helps regulate blood glucose levels through improved insulin sensitivity and release of insulin from the pancreas, control hunger, induce satiety and plays a role in the metabolic health of a person. GLP-1 receptor agonists (GLP1-RAs) have been shown to be effective in achieving weight loss in patients with type 2 diabetes while improving blood glucose control.

Sex-Specific Effects of Endocrine Disruption on Aging and Alzheimer's Disease
Studying whether ovarian hormones are linked to aging and Alzheimer’s risk in women
📍 Mayo Clinic · Jacksonville, FL · +1 more US site · Get directions →
The researchers are trying to determine whether ovarian hormones are associated with aging processes and with the risk of developing Alzheimer's disease in women.
- DepressionDementia / Alzheimer's
Aβ Dynamics in LLMD
Testing how treating depression may change brain markers linked to Alzheimer’s
📍 NYU Langone Health · New York, NY · +1 more US site · Get directions →
This study will examine the biological factors that may modulate the relationship between depression and the development of Alzheimer's disease (AD). Since the direction of causation between depression and the biological factors associated with AD is unknown, the only way to understand cause and associated risk is to treat the depressive symptoms and examine the effects on AD biomarkers.

Compare the Effects of Nebulizer Versus Inhaler Based Therapy for COPD Using Long-acting Bronchodilators
Comparing nebulizer and inhaler treatments for COPD symptoms
📍 The University of Tennessee Graduate School of Medicine · Knoxville, TN · Get directions →
The purpose of this study is to compare the effectiveness of inhaled bronchodilators delivered via nebulizers vs. dry powder inhalers (DPIs) in symptomatic participants with Chronic Obstructive Pulmonary Disease (COPD) who have airflow obstruction (FEV1/FVC ≤ 70%) and show significant air trapping (RV ≥ 120% of predicted).

Optimizing Portal Hypertension With TIPS and Interval Metabolic Surgery for Advanced Liver Disease
Testing treatments to lower high pressure in liver veins in people with advanced liver disease and
📍 Cleveland Clinic Main Campus · Cleveland, OH · Get directions →
Cirrhosis is a form of advanced liver disease that can lead to serious complications, especially when combined with severe obesity. Many patients with cirrhosis also develop a condition called clinically significant portal hypertension (CSPH), which is increased pressure in the veins of the liver.
- Dementia / Alzheimer's
A Study of Zunveyl on Safety, Tolerability, Neuropsychiatric Symptoms, and Caregiver Distress in Alzheimer's Disease (RESOLVE)
Testing the safety and side effects of Zunveyl in people with mild to moderate Alzheimer’s
📍 Tekton Research Saint Louis Psychiatry · St Louis, MO · Get directions →
The primary purpose of this study is to evaluate the safety and tolerability of Zunveyl® over 12 weeks of routine clinical use in adults with mild to moderate Alzheimer's disease.
- Dementia / Alzheimer's
Lemborexant for Insomnia in a Patient With Dementia: An N-of-1 Trial
Testing a sleep medicine for insomnia symptoms in a person with dementia
📍 Nova Scotia Health · Halifax, Nova Scotia · Get directions →
Insomnia is a highly common, chronic disorder that is distressful for the patient but also for caregivers and can give rise to a heavy burden on the healthcare team. Sleeping aids like benzodiazepines and other sedatives (e.g., zolpidem, zopiclone) have been widely used to help treat insomnia.
- Dementia / Alzheimer'sParkinson's disease
Elucidating the Role of Cholinergic Degeneration in Cognitive Fluctuations in Lewy Body Dementia
Studying how nerve cell loss affects thinking ups and downs in Lewy body dementia
📍 Virginia Commonwealth University · Richmond, VA · Get directions →
The proposed study aims to address the critical gaps in understanding the mechanisms of CF (Cognitive Fluctuations) by leveraging recently emerged molecular biomarkers, advanced neuroimaging techniques to assess measures of cholinergic degeneration, and synchronous EEG and assessments of attention. One of the overarching innovations of study is combining all of these assessments into one integrated research plan
- Dementia / Alzheimer's
Nighttime Agitation and Restless Legs Syndrome in People With Alzheimer's Disease
Studying nighttime agitation and restless legs in people with Alzheimer’s
📍 The University of Texas at Austin · Austin, TX · Get directions →
Nighttime agitation in persons with Alzheimer's disease causes patient suffering, distresses caregivers, and often results in prescriptions for harmful antipsychotics. Effective treatments are lacking because of limited knowledge of the etiology of nighttime agitation.
