Asthma Clinical Trials in Madison, WI

This is a Phase 2a, multicentre, randomised, placebo-controlled, double-blind, parallel-group study to evaluate the efficacy, safety and PK of AZD4604 administered BID using a dry-powder inhaler at one dose level over a 12-week Treatment period in adult participants with uncontrolled moderate-to-severe asthma.

The study investigators are interested in learning more about how drugs, that are given to children by their health care provider, act in the bodies of children and young adults in hopes to find the most safe and effective dose for children. The primary objective of this study is to evaluate the PK of understudied drugs currently being administered to children per SOC as prescribed by their treating provider. Read Less

The goal of this clinical trial is to learn about how asthma influences brain function. The main questions it aims to answer are: How airway inflammation in asthma affects the brain; and, Whether airway inflammation in asthma is related to symptoms of depression and anxiety Over the course of 3 visits, participants will: Complete questionnaires Complete computer tasks Undergo allergy skin test and breathing tests Give two blood samples Give a sputum sample Complete brain imaging scans Researchers will compare results between participants with asthma, and participants who do not have asthma.

This study is called the Microbes and Respiratory Illnesses (MARI) Study. Children growing up on farms are exposed to many types of microbes that could be beneficial. It is thought that increased exposure to certain types of microbes early in life helps to develop a healthy immune system and reduce the risk for severe common cold illnesses, breathing problems, and allergies.

The primary purpose of this study is to provide preliminary data to determine if an acute increase in airway inflammation, provoked by an inhaled allergen challenge, is associated with an increase in microglial activation and may inform whether individuals with asthma, in the long-term, are at increased risk for neurodegeneration, cognitive decline, and forms of dementia. Though in the long-term airway inflammation may be associated with neurodegenerative processes, these changes reflect the accumulation over a lifetime of allergen exposures and disease-related changes. This relationship between peripheral inflammation and microglial activation is analogous to the impact of sleep loss. No single night of poor sleep will lead to long-term change in brain structure, function, or cognitive function, but the accumulation of frequent and repeated sleep loss over a lifetime has been shown to have a major impact. These data will be used for a larger scale study to determine if asthma is a risk factor for neurodegeneration, and will inform brain health issues in asthma more broadly. Read Less

The primary objective of this study is to evaluate several interventions given to participants with severe asthma. Interventions are administered in a crossover manner with 16-week treatment periods followed by 8 to 16 week washout. Read Less
