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.
PrecISE is a clinical study sponsored by the U.S. National Heart, Lung, and Blood Institute (NHLBI) to investigate several treatments for severe asthma. PrecISE will enroll 600 adults and teenagers (ages 12 years and older) with severe asthma who have symptoms that are not well-controlled on high dose of inhaled corticosteroids including those who have frequent asthma attacks. Each person who agrees to enroll in the PrecISE study will receive several treatments for research purposes based on their type of severe asthma.
The goal of PrecISE is to understand how to treat different types of severe asthma, by using precision medicine. Precision medicine is an approach that targets treatments to defined subgroups of patients who share similar characteristics, for example, patients with a certain genetic variation or patients with high number of blood eosinophils.
Researchers from over 30 locations across the US are involved in PrecISE.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Medium Chain Triglycerides (MCT) | Experimental | Participants in this arm will receive Medium Chain Triglycerides (MCT) powder packets (12.5 g each) daily for the 16 week treatment period. Participants are assigned one packet per 500 kilocalories required to maintain bodyweight; the target dose for each participant is between 2 and 5 packets daily. Participants will mix the packets of MCT supplement powder into liquids or semi-solid food. Participants will be randomized to the treatment sequence and will receive either the active MCT or the matching placebo first or vice versa. |
|
| Clazakizumab | Experimental | Participants randomized to this arm will receive a 12.5 mg dose of Clazakizumab via a subcutaneous injection at every study visit, every 4 weeks, during the 16-week treatment period at any point in the study. Participants will be randomized to the treatment sequence and will receive either the active Clazakizumab or the matching placebo first or vice versa. |
|
| Broncho-Vaxom | Experimental | Participants randomized to this arm will receive 7 mg of Broncho-Vaxom once a day on an empty stomach for the 16-week treatment period duration at any point in the study. Participants will be randomized to the treatment sequence and will receive either the active Broncho-Vaxom or the matching placebo first or vice versa. |
|
| Imatinib | Experimental | Participants randomized to this arm will take two 100 mg Imatinib tablets orally once a day with a meal and an 8 oz glass of water for 2 weeks. Participants will then take four 100 mg tablets once a day with a meal and an 8 oz glass of water for 14 weeks. Participants will be randomized to the treatment sequence and will receive either the active Imatinib or the matching placebo first or vice versa. |

| Forced Expiratory Volume in One Second (FEV1) Percent Predicted | Assessed prior to bronchodilator administration. Efficacy analyses will compare the end-of-period outcome values between test treatment and placebo. | Measured at 16 weeks after the start of treatment. |
| The Juniper Asthma Control Questionnaire (ACQ-6) | Asthma symptom control is assessed via ACQ-6, the average score of these six items (range 0-6). The seven-point response scale: 0 = 'totally controlled' and 6 = 'severely uncontrolled'. Negative change from baseline values indicate improved asthma control. Efficacy analyses will compare the end-of-period outcome values between test treatment and placebo. | Measured at 16 weeks after the start of treatment. |

| CompEx Events Per Year | Composite outcome with exacerbations (CompEx) is an outcome specific to asthma and chronic obstructive pulmonary disease (COPD) that combines clinically-relevant deteriorations with exacerbations. Deterioration events defined based on daily recordings of peak expiratory flow (PEF) morning/evening (L/min), reliever use morning/evening (doses), symptoms morning/evening (score 0-3) from twice-daily recordings. Participants are asked to describe their morning and evening symptoms using the following scale: 0-No symptoms to report, 3-I could not sleep because of my asthma/I could not perform my normal activities because of my asthma. |

| Secondary | CompEx Events Per Year | Composite outcome with exacerbations (CompEx) is an outcome specific to asthma and chronic obstructive pulmonary disease (COPD) that combines clinically-relevant deteriorations with exacerbations. Deterioration events defined based on daily recordings of peak expiratory flow (PEF) morning/evening (L/min), reliever use morning/evening (doses), symptoms morning/evening (score 0-3) from twice-daily recordings. Participants are asked to describe their morning and evening symptoms using the following scale: 0-No symptoms to report, 3-I could not sleep because of my asthma/I could not perform my normal activities because of my asthma. | Posted | Mean | 95% Confidence Interval | CompEx events per year | Assessed over 16 weeks of treatment |

| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Secondary | Exacerbations | Annualized rate of severe exacerbations during the 16-week treatment periods, modified intent-to-treat (mITT) population. An asthma exacerbation in PrecISE is defined as a worsening of asthma requiring the use of a systemic corticosteroid (at least 3 days of treatment) to prevent a serious outcome. | Posted | Mean | 95% Confidence Interval | exacerbations per year | Assessed over 16 weeks of treatment |
| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Secondary | Number of Participants With At Least One Asthma-Free Day | An asthma free day is a day where 1) there is no use of albuterol rescue (excluding the use of albuterol as pre-exercise treatment), 2) no daytime or nighttime asthma symptoms, 3) no peak expiratory flow of less than 80% of the predetermined reference value. | Posted | Count of Participants | Participants | Assessed over 16 weeks of treatment |
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Secondary | Number of Participants With At Least One Symptom-free Day | A symptom free day is a day with no asthma symptoms (symptom score = 0) for both morning and evening daily diary entries. | Posted | Count of Participants | Participants | Assessed over 16 weeks of treatment |
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Secondary | Healthcare Utilization | The combined total number of: asthma-specific Emergency Department visits, asthma-specific hospital admissions, and asthma-specific ICU admissions. The investigators report the number of participants with at least one asthma-specific Emergency Department visit, asthma-specific hospital admission, or asthma-specific ICU admission | Posted | Count of Participants | Participants | Assessed over 16 weeks of treatment |
|
The observation time began with run-in and continued through the total number of treatment and washout periods. The maximum observation time was 124 weeks. Adverse events are reported for each treatment period combined with the washout. The length of treatment period combined with washout is 16 weeks of treatment plus 8 weeks washout (except 16 weeks washout following clazakizumab).
