NCT02153541

Brief Summary

This is a double-blind, randomized, placebo-controlled, proof of concept, study in adults with poorly controlled moderate to severe asthma. The researchers believe that by using a local anesthetic to block a certain nerve in the ear, it will improve all aspects of asthma, such as decreasing the numbers of times patients have to use a rescue inhaler, and improving asthma treatment assessment questionnaire scores, with no bad changes to lung function and inflammation.

Outcome Measures

Primary Outcomes (1)

  • Efficacy of CREWS01 (topical auricular anesthesia of the vagus nerve) to decrease usage of rescue inhalers in moderate to severe asthmatic adults Change in usage of rescue inhalers in moderate to severe asthmatic adults in four weeks

    We anticipate 50% of patients that receive the active ingredient will decrease the usage of rescue inhalers by 50%. If the test of the two-factor interaction in the repeated measures mixed model analysis is statistically significant, and the magnitude of the change in the Crews group is at least 50%, the Crews Maneuver will be considered effective.

    Each participant is studied for four weeks

Secondary Outcomes (1)

  • Improvement of spirometry scores in moderate to severe asthmatic adults

    Each participant is studied for four weeks

Other Outcomes (1)

  • Evaluate the safety of using topical anesthetics in moderate to severe asthmatic adults

    Each participant is studied for four weeks

Study Arms (2)

Glycerin with Oxyquinoline Sulfate

PLACEBO COMPARATOR

For those participants who receive glycerin with oxyquinoline sulfate placebo, we do not anticipate any change in the usage of rescue inhalers, spirometer scores, asthma diaries, and expired fractionated nitrous oxide levels.

Other: Glycerin with Oxyquinoline Sulfate

Antipyrine-benzocaine otic solution

ACTIVE COMPARATOR

Will be used on 50% of participants, we anticipate reduction in the usage of rescue inhalers, spirometer scores, asthma diaries, and expired fractionated nitrous oxide levels.

Drug: Antipyrine-benzocaine otic solution

Interventions

Participants receiving antipyrine-benzocaine otic solution are expected to decrease usage of rescue inhalers.

Antipyrine-benzocaine otic solution

50% of participants will receive the glycerin with oxyquinoline sulfate. These participants will be randomly selected and unaware that they are receiving the placebo and are expected to have no change in usage of rescue inhalers.
