Use of fenoTRACK Device for Monitoring Changes of Fractional Exhaled Nitric Oxide (FeNO) in Uncontrolled Asthma Subjects and Controlled Asthma Subjects
A Combined Prospective, Multicenter, Non-Randomized, Open-Label, Point-of-Care and Home Use Pivotal Study of the fenoTRACK Device for Monitoring Changes of Fractional Exhaled Nitric Oxide (FeNO) in Non-Steroid-Treated Adult and Pediatric Uncontrolled Asthma Subjects and a Prospective Multicenter Clinical Precision Evaluation for Point-of-Care and Home Use in Adult and Pediatric Controlled Asthma Subjects

Brief Summary
This study incorporates objectives directed at two subject cohorts:
- To evaluate within-session clinical precision during Visit 1 and Visit 2 for the fenoTRACK device for simulated at home FeNO, and at POC
- To evaluate within-session clinical precision for home fenoTRACK use

Outcome Measures
Primary Outcomes (1)
Uncontrolled Cohort - Magnitude of change in FeNO Values
Magnitude of change, expressed both as absolute and percentage change in FeNO values in the uncontrolled cohort from Visit 1 to Visit 2.
Visit 2 (Day 14)
Secondary Outcomes (6)
Uncontrolled Cohort - Magnitude of change (POC)
Visit 2 (Day 14)
Uncontrolled Cohort - Magnitude of change (Home Use)
Day 1 and Day 2 AM and PM FeNO values compared to average of the last 2 Days prior to Visit 2
Uncontrolled Cohort - Change in 7-item ACQ/ACQ-IA
Visit 2 (Day 14)
Uncontrolled Cohort - Change in best spirometry measures
Visit 2 (Day 14)
Controlled cohort - Clinical precision based on the first 2 FeNO results - Within-session clinical precision in a simulated home-use environment (V1 and V2) - Within-session clinical precision at the POC (V1 and V2) - Clinical precision at home
Visit 2 (Day 14)
- +1 more secondary outcomes
Study Arms (2)
Uncontrolled Asthma Subjects
fenoTRACK for Uncontrolled Adult and Pediatric Asthma Subjects
Controlled Asthma Subjects
fenoTRACK for Controlled Adult and Pediatric Asthma Subjects
Interventions
Home FeNO Monitoring: FeNO measurement will be performed. POC Longitudinal Response to Treatment: FeNO measurement will be performed in the office both the simulated home environment and POC environment.
Eligibility Criteria
The study population includes two distinct cohorts. The first cohort comprises male and female subjects aged 5 and above with uncontrolled asthma (See uncontrolled Asthma subject Inclusion Criteria). The second cohort comprises male and female subjects aged 5 and above with controlled asthma. If one of the subject cohorts completes before the other, the Sponsor reserves the right to analyze that cohort first.
You may qualify if:
- The subject is male or female age 5 years and above
- The subject and/or their Legally Authorized Representative (LAR) in the case of a minor has signed an Informed Consent Form (ICF) and Assent (as applicable per IRB requirements) and understands the risks and benefits of the study
- The subject has a diagnosis of asthma
- The subject is willing and able to perform all study procedures
- The subject must have uncontrolled asthma as defined by the presence on at least 2 days per week (can be non-consecutive days) in the 7 days prior to V1 of at least 3 symptoms from the following list:
- i. Cough ii. Wheezing iii. Shortness of breath iv. Chest tightness v. Nocturnal awakening with asthma vi. Limitation in activity due to asthma
- The subject has a FeNO value based on the first measurement of at least 30 ppb if an adult or at least 25 ppb if \<18 years old measured on a cleared FeNO device (e.g., NIOX VERO®)
- The subject is male or female age 5 years and above
- The subject and/or their Legally Authorized Representative (LAR) in the case of a minor has signed an Informed Consent Form (ICF) and Assent (as applicable per IRB requirements) and understands the risks and benefits of the study
- The subject has an established diagnosis of asthma for at least 180 days prior to V1
- The subject is willing and able to perform all study procedures
You may not qualify if:
- The subject is in need of immediate referral to the emergency department
- The subject has taken the following medications in the indicated period before V1:
- OCS within 4 weeks
- ICS within 2 weeks
- The subject has a contraindication to corticosteroids.
- The subject has demonstrated significant non-compliance during a previous clinical trial
- The subject participated in any clinical study involving a drug, biologic, or device within 30 days prior to V1 or within 5 half-lives for drugs, whichever duration is shorter
- The subject has other significant respiratory conditions, e.g., Chronic Obstructive Pulmonary Disease, cystic fibrosis
- Subject is an employee/relative of the following:
- Biometry Inc.
- Contract Research Organization(s) running the study
- Investigational Site
- Study Vendors
- Any other condition(s), that in the Investigator's opinion, make it undesirable for the subject to participate in the study
- A ≥ 10 pack-year history of smoking or smoking in the 180 days prior to V1 (pack years = average packs/day x years of exposure) Note: smoking includes cigarettes, electronic cigarettes, cigars, and chewing or dipping tobacco
- +12 more criteria
