PrecISE (Precision Interventions for Severe and/or Exacerbation-Prone Asthma) Network Study
a study on Asthma
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 800 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, as well as sites in Canada and the United Kingdom, are involved in PrecISE.

Safety Exclusion Criteria:
Participants who meet the following criteria will be excluded from the study:
- Hemoglobin <10 g/dL
- Absolute Neutrophil Count (ANC) <1000/µl for black participants, <1500/µl for other participants
- Lymphocytes <500/µl

- Bilirubin ≥2x ULN
- Estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 sq m
- Positive Human Immunodeficiency Virus, Types 1 & 2 (HIV 1&2) Ab/Ag immunoassay followed by a confirmatory positive test (Geenius™ HIV-1/HIV-2 antibody differentiation immunoassay)
- Positive Hepatitis B surface Ag (active infection) or Hepatitis B core total antibody (marker of past infection that could reactivate)
- . Positive Hepatitis C RNA test following positive Hepatitis C Antibody
- . EKG with significant clinical findings
A positive QuantiFERON-TB (tuberculosis) Gold test requires further screening. A participant may be included in PrecISE if at least one of the following criteria are met:
- A chest radiograph (CXR) done within the last six months of the test that shows no evidence of active TB
- A chest CT scan done within the last six months of the test that shows no evidence of active TB
- Documentation of adequate treatment for latent TB In cases of an indeterminate QuantiFERON-TB test result, a second blood specimen must be drawn. A chest x-ray is not required if the participant has a negative QuantiFERON-TB Gold test.
Comorbidities are commonly present in severe asthma. Specific questionnaires will be used to identify common comorbidities as follows:
- Sleep apnea: STOP-BANG
- GERD (GERD- Questionnaire)
- VCD (Pittsburgh vocal cord dysfunction index)
- Chronic Rhinitis Sinusitis (Sinonasal questionnaire-SNQ5)
- Depression-Anxiety (Hospital anxiety and depression Scale: HADS) These questionnaires are best used as screening tools. As such they typically have high sensitivity but relatively low specificity. Many of their symptoms overlap with the symptoms reported by participants with asthma who do not suffer from these conditions. Therefore, participants who meet the established cut offs for these questionnaires will need to be evaluated by the investigator to consider the clinical significance of the positive questionnaire based on history and physical and available testing. The investigator will need to judge the presence, severity and control of a specific condition and determine if it is sufficiently controlled to keep the participant in the PrecISE protocol. If the comorbid condition(s) is/are not adequately controlled, the investigator may refer the participant for further evaluation/treatment, prior to enrollment in PrecISE. Rescreening is permitted (after at least four weeks) to determine if the participant is able to move forward in PrecISE once the comorbid condition(s) is/are under adequate control. It is expected that some of the participants may also have other conditions such as cardiovascular disease, diabetes and obesity. These should be evaluated clinically as part of the complete history and physical done at initial evaluation. Their inclusions should be based on the investigator clinical judgement in line with good clinical practice principles.
