A Study to Assess How Food Affects the Safety and Pharmacokinetics of Galicaftor and Navocaftor

A Food-Effect Study for the Safety and Assessment of Pharmacokinetics of Navocaftor and Galicaftor.

Cystic Fibrosis (CF) is a rare, life-threatening, genetic disease that affects the lungs and digestive system, significantly impairing the quality of life, with those affected having a median age of death at 40. The objectives of this study are to assess the effect of food on the safety and pharmacokinetics of navocaftor and galicaftor.

Inclusion Criteria:

• Body Mass Index (BMI) is => 18.0 to <= 32.0 kg/ m2 after rounding to the tenth's decimal.
• A condition of general good health, based upon the results of a medical history, physical examination, vital signs, laboratory profile and a 12-lead electrocardiogram (ECG).

Exclusion Criteria:

• History of epilepsy, any clinically significant cardiac, respiratory (except mild asthma as a child), renal, hepatic, gastrointestinal, hematologic, or psychiatric disease or disorder, or any uncontrolled medical illness.
• History of or active medical condition(s) or surgical procedure(s) that might affect gastrointestinal motility, pH, or absorption [e.g., Crohn's disease, celiac disease, gastroparesis, short bowel syndrome, gastric surgery (except pyloromyotomy for pyloric stenosis during infancy), cholecystectomy, vagotomy, bowel resection, etc.].
• Evidence of dysplasia or history of malignancy (including lymphoma and leukemia) other than successfully treated non-metastatic cutaneous squamous cell, basal cell carcinoma or localized carcinoma in situ of the cervix.
