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.

Condition or disease Intervention/treatment Phase
Asthma Drug: Antipyrine-benzocaine otic solution Other: Mineral oil Phase 2

Detailed Description:

The proposed four-week, double-blind, placebo controlled study is designed to test the hypothesis that topical auricular anesthesia of the vagus nerve decreases the need for the usage of rescue inhalers in moderate to severe asthma in adults.

We anticipate that up to 50 patients will be enrolled in the trial. Particularly severe risks are not anticipated based on the prior investigational experience with this drug. This trial will be used to generate experience and data to support the design of a larger, crossover, comparator trial investigating the efficacy of antipyrine- benzocaine in reducing the need for rescue inhalers and hospital admissions in moderate to severe asthmatic adults.

Arm Intervention/treatment
Placebo Comparator: Mineral oil
For those participants who receive mineral oil placebo, we do not anticipate any change in the usage of rescue inhalers, spirometer scores, asthma diaries, and expired fractionated nitrous oxide levels.
Other: Mineral oil
50% of participants will receive the mineral oil. 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.
Other Name: mineral oil, liquid paraffin

Active Comparator: Antipyrine-benzocaine otic solution
Will be used on 50% of participants.
Drug: Antipyrine-benzocaine otic solution
Participants receiving antipyrine-benzocaine otic solution are expected to decrease usage of rescue inhalers.

Primary Outcome Measures :
  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 [ Time Frame: Each participant is studied for four weeks ]

Secondary Outcome Measures :
  1. Improvement of spirometry scores in moderate to severe asthmatic adults [ Time Frame: four weeks for each participant ]

Other Outcome Measures:
  1. Evaluate the safety of using topical anesthetics in moderate to sever asthmatic adults [ Time Frame: four weeks ]
