Durability of Hypertonic Saline for Enhancing Mucociliary Clearance in Cystic Fibrosis

Completed · Phase 1

Conditions studied: Cystic Fibrosis

In brief

Direct measurement of mucociliary and cough clearance (MCC/CC) has been used as a biomarker in cystic fibrosis (CF). Additional knowledge of the performance of this biomarker is needed to inform exploratory clinical trial design in support of programs to develop new inhaled therapies for CF. We hypothesize that MCC/CC measurements can be used to determine the durability of action of agents like hypertonic saline (HS) which increase epithelial lining fluid height.

You may qualify if…

Gender: Male or female (non-pregnant, non-lactating)
Cystic fibrosis documented by a compatible clinical and radiographic presentation, and sweat chloride > 60 mEq/l or 2 disease causing CFTR mutations.
Severity of Disease:
Must have FEV1 of greater than or equal to 50% of predicted at the screening visit.
Must have an oxygen saturation of >92% on room air as determined by pulse oximetry at the screening visit.
Patient or legally authorized representative agrees to the patient/individual's participation in the study by signing and dating the informed consent form after the nature of the study has been fully explained and all questions have been satisfactorily answered.

You may not qualify if…

Unstable lung disease: As defined by a change in medical regimen during the preceding 2 weeks; an FEV1 >15% below recent (within 6 months) clinical measurements; or a significant new finding on chest radiograph (pneumothorax, lobar/segmental collapse) not considered a part of the usual, chronic progression of CF lung disease.
Patients unable or unwilling to be withdrawn from hypertonic saline therapy, dornase alfa, or N-acetylcysteine 3 days prior to and for the duration of each Baseline and Treatment Period will be excluded.
Patients unable to withhold use of long-acting bronchodilators (i.e., Salmeterol, Advair, Formoterol), anti-cholinergics, and vest therapy 12 hours prior to and for the duration of each treatment period.
Patients unable to withhold short-acting bronchodilator 6 hours prior to and for the duration of each treatment period except as prescribed by the study protocol.
Patients that have received an investigational drug or therapy during the preceding 30 days.
Patients that have had radiation exposure within the past year that would cause them to exceed Federal Regulations by participating in this study.
