About this study

The overall goal of the Asthma Inflammation Research [AIR] Translational Program is to create an integrated multidisciplinary team for the focused purpose of development of diagnostic and prognostic tests informative for airway inflammation, and for the design of innovative, targeted biologic therapeutics.

The overarching aims of the AIR program are to conceptualize, develop, and test the next-generation therapeutics, and novel asthma diagnostic and prognostic tools that will allow us to improve the standard of asthma care.

Read the detailed description

More than 20 million Americans suffer from asthma, and nearly half of asthma sufferers do not have their asthma under control. Although commonly diagnosed using physiological measures of airflow and bronchial hyperreactivity, asthma pathophysiology is related to chronic inflammation of the airway.

Current diagnostic evaluation and monitoring are inadequate for proposed practice guidelines. The most commonly used test for evaluation of asthma is the measurement of airflow obstruction by spirometry. The National Asthma Education Prevention Program (NAEPP) and Expert Panel Reports set forth grading of asthma severity based on the frequency of symptoms, airflow, and the need for inhaled beta-agonists. Practice guidelines outline that the goals of therapy for asthma are to: maintain normal activity with near normal parameters of lung function, prevent exacerbations that lead to tissue injury, and avoid medication toxicity. In order to facilitate these goals, NAEPP defines key components for management including disease monitoring and stepped care pharmacotherapy. Unfortunately, there is no optimal plan for monitoring inflammation, which causes us to fail in key components in management of asthma. Limited options for anti-inflammatory treatments to control asthma likewise often lead to substantial morbidities due to treatment with high doses of corticosteroids. Our AIR program plans to develop novel asthma monitoring tests and design targeted therapeutics, which altogether may reduce toxicities and improve the long-term health of patients.

Impact on broad scientific advancement. Our cumulative studies provide fundamental information on the molecular mechanisms that contribute to unresolving and excessive inflammation that leads to tissue remodeling. This mechanistic knowledge is of broad scientific importance as nearly all chronic human diseases are defined by prolonged and active inflammation, with tissue destruction, and failed attempts at healing. Thus, our investigations will provide comprehensive knowledge and consequent translational deliverables that may be widely applicable as diagnostic strategies and therapies in other chronic inflammatory diseases.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Nutritional approach for asthmaDietary supplement

    Also called MCT supplement

    participants will be provided a medium chain triglyceride supplement or placebo

  • Low Caloric ShakeDietary supplement

    participants will be provided a low caloric dietary shake

  • whole lung allergen challengeBiological

    inhalation of allergens by allergic patients with or without asthma, will be used to define mechanisms underlying the development of airway inflammation

Study groups in NCT01536522
Study groupRoleWhat they receive
Nutritional Approach for AsthmaActive comparatorindividuals will be provide a pre measured dose of medium chain triglyceride to consume along with their meals. They will be instructed to add the MCT to their meal 3 times per day
Receives: Dietary Supplement: Nutritional approach for asthma
Standard American DietPlacebo comparatorpatients will consume their usual diet with a pre measured dose of canola oil in place of the medium chain triglyceride as a control group. They will be instructed to add the placebo dose to their meal 3 times a day
Receives: Dietary Supplement: Nutritional approach for asthma
Alternate Day DietActive comparatorpatients will consume a regular "Standard American Diet" for 4 weeks and then provided a regulated dosed quantity of low caloric value "shakes". they will consume this on alternating days
Receives: Dietary Supplement: Low Caloric Shake
Whole Lung Allergen ChallengeActive comparatorpatients with or without asthma will be given controlled doses of specified allergens
Receives: Biological: whole lung allergen challenge

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Maintaining a tolerance to Medium Chain Triglyceride (MCT) additive for Asthmatics

    Tolerability of the MCT will be assessed by maintenance of use of MCT by 20% or more participants over the 3 months of the study.

    Measured: 24 weeks

Secondary outcomes (4)
  1. Improvement of lung function by spirometry testing

    Quantitative data will be collected to evaluate any improvement mechanistically in the lungs using breathing tests

    Measured: 24 weeks

  2. Asthma Quality of Life Questionnaire

    Asthma Quality of Life Questionnaire will be evaluated for any decrease in asthma symptoms by a 7 point scale. 7 is not impaired and 1 is severely impaired. The higher the total score will determine better quality of life

    Measured: 24 weeks

  3. Asthma Control Test

    Asthma control test will be used to score improvement in day to day activities using a 5 point lscale. A score of 1 equals all of the time and a score of 5 equals not at all. The score ranges of 5 (poorly controlled) to 25 (complete control). A total ACT score greater than 19 indicates asthma is well controlled

    Measured: 24 weeks

  4. Gastrointestinal tolerance of a Medium Chain Triglyceride additive to a normal diet in Asthmatics

    GI symptoms will be documented and data captured to measure tolerance via a 5 point scale. A score of 1 equals symptoms all of the time and 5 equals never. The greater the score indicates less or no GI symptoms.

    Measured: 12

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Nutritional approach for asthma, Low Caloric Shake and whole lung allergen challenge in people with Asthma and Allergic Asthma, run by The Cleveland Clinic at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: enrolling by invitation, as of the sponsor's last update on 28 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Maintaining a tolerance to Medium Chain Triglyceride (MCT) additive for Asthmatics (time frame: 24 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01536522, which also lists 15 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 May 2026.
