Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||18 Years and Over|
Inclusion Criteria:1. 18 years and older. 2. Confirmed diagnosis of cystic fibrosis (CF) and CF lung disease including:
- - Bi-allelic mutations in the CFTR gene, and.
- - Ineligible for CFTR modulator therapy, or previously received modulator therapy but discontinued due to adverse effects.
Exclusion Criteria:1. Any prior gene therapy for any indication. 2. History of positive culture for Burkholderia cenocepacia, B. dolosa, or Mycobacterium abscessus within the past 24 months. 3. Active allergic bronchopulmonary aspergillosis requiring management with systemic corticosteroids or antifungal therapy. 4. Contraindication to systemic corticosteroid therapy. 5. Requires chronic use of systemic corticosteroids or immunosuppressants to treat another condition. 6. If no known diagnosis of cystic fibrosis related diabetes (CFRD), Type I, or Type II diabetes: Hemoglobin A1C ≥6.5% at Screening. 7. If known diagnosis of CFRD, Type I or Type II diabetes: Hemoglobin A1C >7.5% at Screening. 8. Recent history of symptomatic hyperglycemia or unstable blood glucose levels as per Investigator's assessment. 9. Other conditions that, in the Investigator's opinion, may interfere with management of corticosteroid-related hyperglycemia. 10. Body Mass Index (BMI) <16. 11. Laboratory abnormalities at screening:
- - ALT, AST or GGT ≥ 3 × the upper limit of normal (ULN) - Total bilirubin ≥ 2 × ULN.
- - Hemoglobin < 10 g/dL.
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

|Cystic Fibrosis Lung|
This Phase 1/2 trial will evaluate the safety, tolerability, and preliminary efficacy of 2 dose levels of 4D-710, an investigational gene therapy, in adults with cystic fibrosis lung disease who are ineligible or unable to tolerate CFTR modulator therapy.
Experimental: 4D-710 Dose Exploration Cohort 1
Single inhalational administration of 4D-710 Dose Level 1
Experimental: 4D-710 Dose Exploration Cohort 2
Single inhalational administration of 4D-710 Dose Level 2
Experimental: 4D-710 Dose Expansion Cohort
Single inhalational administration of 4D-710 at the selected dose
Biological: - 4D-710
4D-710 is an adeno-associated virus (AAV) gene therapy comprised of an AAV capsid variant (4D-A101) carrying a transgene cassette encoding human cystic fibrosis transmembrane conductance regulator with a deletion in the regulatory domain (CFTRΔR).
