About this trial

This is a prospective, observational study examining the impact of highly effective cystic fibrosis transmembrane conductance regulator (CFTR) modulators on chronic rhinosinusitis (CRS) and olfactory dysfunction (OD) in young children with cystic fibrosis (YCwCF). This study involves two groups: children 2-8 years old, inclusive at initial visit, receiving highly effective modulator therapy (HEMT), and a control group of children 2-8 years old, inclusive at initial visit, not receiving HEMT. Outcomes will include sinus magnetic resonance imaging (MRI) scans, olfactory tests, and quality of life surveys obtained over a two-year period.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Children with documentation of a CF diagnosis

Age 2-8 years old at first study visit

CFTR mutation consistent with FDA labeled indication of highly effective modulator therapy (ivacaftor or elexacaftor/tezacaftor/ivacaftor)

Clinician intent to prescribe ivacaftor or ETI so that enrollment is before start of HEMT

Disqualifiers

Use of an investigational drug within 28 days prior to the first study visit

Use of ivacaftor or elexacaftor/tezacaftor/ivacaftor within the 180 days prior to and including the first study visit

Use of chronic oral corticosteroids within the 28 days prior to and including the first study visit.

Sinus surgery within 180 days prior to the first study visit

Trial population

Participants for this study will be enrolled into one of two groups. The first group (HEMT Group) will enroll children between 2-8 years of age who have a clinical intent to initiate HEMT, which is defined as ivacaftor or elexacaftor/tezacaftor/ivacaftor based on underlying CFTR mutation status. The second group (non-HEMT Group) will consist of children under the age of 8 without intent to clinically initiate HEMT. Children for both groups will be identified and recruited from cystic fibrosis clinics.

Trial outcomes

Primary outcomes

1

Change in MRI sinus opacification

Measurement involves calculating percent total sinus opacification (%) using MRI, where sinus contents are differentiated into air and soft tissue/fluid.

Time frame
Baseline, 1-year, and 2-year follow-up
2

Change in olfactory bulb volume

Assessment includes segmenting the olfactory bulb on consecutive coronal slices using MRI, then combining these into a 3-dimensional region. The volume of this region is then calculated in cubic millimeters (mm3).

Time frame
Baseline, 1-year, and 2-year follow-up

Secondary outcomes

1

Change in Pediatric Smell Wheel (PSW) Scores

The PSW test involves children identifying microencapsulated odorants. The score (Range: 0-11) is based on the number of correctly identified smells, with higher scores indicating better olfactory function.

Time frame
Baseline, 1-year, and 2-year follow-up
2

Olfactory Cleft Opacification

Olfactory cleft opacification is quantified by segmenting the olfactory cleft on MRI and applying pixel intensity thresholds to calculate the percentage (%) of opacification.

Time frame
Baseline, 1-year, and 2-year follow-up
3

Change in Brief Questionnaire of Olfactory Disorders (BQOD) Scores

This BQOD is a parent-completed survey for assessing olfactory-specific quality of life (QOL). The survey scores (Range: 0-21) quantify the degree of olfactory QOL impairment, with higher scores indicating greater olfactory QOL impairment.

Time frame
Baseline, 1-year, and 2-year follow-up
4

Change in Sinus and Nasal Quality of Life Survey (SN-5) - Symptom Frequency Domains

SN-5 is a parent-completed survey assessing sinus symptoms and QOL in children. It captures sinus infections, nasal obstruction, allergy symptoms, emotional distress, activity limitations, and overall QOL. For the first five symptom domain questions, scores range 1-7 for each domain, higher scores indicating higher frequency at which symptom affected patient over the past 4 weeks.

Time frame
Baseline, 1-year, and 2-year follow-up
