Primary Outcome Measures :
  1. Types, frequency and severity of treatment-emergent Adverse Events [ Time Frame: 12 months after last dose ]
    Safety and tolerability of nebulized MRT5005 will be assessed through the types, frequency and severity of treatment-emergent Adverse Events experienced by participants on the trial

Secondary Outcome Measures :
  1. Biological activity of nebulized MRT5005 [ Time Frame: 4 weeks after last dose ]
    Changes from baseline in ppFEV1

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Confirmed diagnosis of CF as defined by both of the following:

    • Two CF disease-causing CFTR mutations in Class I or II (genotype confirmed at the screening visit).
    • Chronic sinopulmonary disease and/or gastrointestinal/nutritional abnormalities consistent with CF disease.
  • Clinically stable CF disease, as judged by the investigator.
  • FEV1 ≥50% and ≤90% of the predicted normal for age, gender, and height at screening.
  • Resting oxygen saturation ≥92% on room air (pulse oximetry).

Exclusion Criteria:

  • An acute upper or lower respiratory infection, pulmonary exacerbation, clinically significant episode of hemoptysis or change in chronic respiratory medications (including antibiotics) for CF lung disease within 28 days prior to dosing with investigational product on Day 1.
  • Receiving treatment with ivacaftor monotherapy (KALYDECO)
  • For all groups except Daily dosing: Receiving treatment with triple combination therapy (TRIKAFTA).
  • Subjects with a Class III, IV, or V CFTR gene mutation in at least 1 allele.
  • Infection with highly virulent bacteria associated with accelerated decline in pulmonary function and/or decreased survival (e.g., Burkholderia cenocepacia, Burkholderia dolosa, Mycobacterium abscessus).

Treatment with ORKAMBI or SYMDEKO is not an exclusion for this study.
