Asthma Clinical Trials in Nashville, TN

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

This research will establish a mg/kg dose for a future RCT to determine the efficacy of high-dose oral montelukast for children with moderate and severe acute asthma exacerbations. Aim: Perform an adaptive, double-masked randomized controlled trial (RCT) of high-dose oral montelukast, with escalating mg/kg dose levels determined by PK-guided dose modeling, added to standard treatment versus standard treatment alone, in children with exacerbations that are moderate or severe after initial treatment with inhaled albuterol. Hypothesis 1: High-dose oral montelukast achieves peak plasma concentration (Cmax) >1,700 ng/ml in >86% of at least one of three sequential participant groups with escalating weight-based (milligram/kilogram or mg/kg) doses between groups. Hypothesis 2: Participants randomized to high-dose oral montelukast have a 2 point or greater improvement of the validated Acute Asthma Intensity Research Score (AAIRS) at 4 hours post-treatment in comparison with control group participants. Hypothesis 3: Among montelukast recipients, Cmax correlates with change of the AAIRS at 4 hours, after adjustment for pre-treatment exacerbation severity and systemic leukotriene stress measured using urinary leukotriene E4 (LTE4).

This is a randomized placebo-controlled trial of semaglutide, an FDA-approved therapy for the treatment of type 2 diabetes mellitus and obesity, in adults with symptomatic asthma despite the use of inhaled steroids and with excess body weight. This study will test the central hypothesis that semaglutide will improve asthma control and reduce airway inflammation due to direct effects on the respiratory tract in adult asthma associated with obesity.

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
