NCT03762395

Brief Summary

The main purpose of this Phase 2 double blind, placebo controlled crossover clinical study is to demonstrate the efficacy and safety of CXA-10 in obese adult asthmatics. Obesity induces a chronic systemic inflammatory state characterized by impaired adipokine signaling, pro-inflammatory cytokine responses, inflammatory cell activation and enhanced generation of oxidative inflammatory mediators. This impacts the lung, increasing the severity of asthma and its exacerbations. This research will evaluate how a synthetic nitro-fatty acid (CXA-10, 10-nitro-octadec-9-enoic acid) suppresses the systemic and airway inflammation that contributes to the obese asthmatic phenotype. Current data support the pleiotropic signaling actions of CXA-10 to induce adaptive signaling actions that beneficially modulate adipokine and cytokine expression and inhibit systemic and pulmonary inflammation. The investigators hypothesize that CXA-10 induced signaling responses will alleviate obesity-related airway hyperreactivity in obese adult asthmatics.

Outcome Measures

Primary Outcomes (2)

  • Change in Methacholine challenge dose per spirometry

    To determine CXA-10 efficacy, reduction of bronchial hyperresponsiveness determined by performing spirometry to see if there's a change in methacholine dose

    Through study completion, up to 18 weeks

  • Changes in pre-bronchodilator FEV1 per spirometry

    To determine the efficacy of CXA-10 by improving FEV1

    Through study completion, up to 18 weeks

Study Arms (2)

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adequate completion of informed consent process with written documentation. Male and female patients, 18 to 65 years old. Female subjects should be either post-menopausal or surgically sterile, or, if child-bearing potential (WOCP) should agree to use an acceptable method of contraception, for the duration of the study, with a negative pregnancy test prior to entering the study.
  • BMI \>/= 30
  • Diagnosis of asthma: based on previous physician diagnosis for \> 6 months, and baseline pre-bronchodilator (BD) FEV1 between 50 and 95% predicted with either a 12% or greater bronchodilator response to 4 puffs of albuterol or PC20 methacholine (16 mg) if \<12% change post BD
  • Regular treatment with inhaled corticosteroids (ICS) (up to 1000 mcg/day fluticasone/equivalent), long acting beta agonists (LABA), and/or long-acting muscarinic antagonists (LAMA), which can be combination medication for at least 3 months; on a stable dose for the 4 weeks prior to Visit 0

You may not qualify if:

  • Respiratory tract infection within the last 4 weeks
  • Oral or systemic corticosteroid burst within the last 4 weeks
  • Asthma-related hospitalization within the last 6 weeks
  • Three or more asthma exacerbations requiring treatment with systemic corticosteroids in the past year consistent with severe asthma
  • Asthma-related ER visit within the previous 4 weeks
  • Current smoking or have former smokers that quit within the previous 1 year, or 10 pack years
