ClinConnect Summary
This clinical trial is testing a new drug called RCT2100 to see if it is safe and well-tolerated in both healthy adults and those with cystic fibrosis (CF). This is the first time RCT2100 is being given to people, and the results will help researchers understand how it affects the body and prepare for future studies. The trial is currently looking for participants, including healthy adults aged 18 to 55 and individuals with CF who meet specific health criteria.
To be eligible, healthy participants need to be in good overall health, have a certain level of lung function, and meet other basic health requirements. For those with CF, they must have a confirmed diagnosis and specific lung function levels while not currently using certain CF medications. Participants can expect to undergo health screenings to ensure they qualify for the study and will receive close monitoring during the trial. This is an important step in developing new treatments for cystic fibrosis, and taking part could contribute to future advancements in care.

- • a) Not eligible for CFTR modulators based on having mutations of CFTR gene on both alleles that are not responsive to CFTR modulator therapy OR
- • b) Eligible for CFTR modulators (based on local prescribing information) but not using CFTR modulators due to intolerance or contraindications
- Part 2 Major Exclusion Criteria:
- • Hepatic cirrhosis with portal hypertension, moderate hepatic impairment (Child Pugh Score 7 to 9), or severe hepatic impairment (Child Pugh Score 10 to 15)
- • An acute upper or lower respiratory infection, pulmonary exacerbation, or changes in therapy (including antibiotics) for sinopulmonary disease within 4 weeks before the first dose of study drug
- • Lung infection with organisms associated with a more rapid decline in pulmonary status
- • Arterial oxygen saturation on room air less than 94% at screening
- • Values of AST, ALT, alkaline phosphatase, or gamma-glutamyl transferase (GGT) ≥3×ULN
- • Treatment with a CFTR modulator (Kalydeco, Trikafta, Symdeko, or Orkambi) within 12 weeks of Screening
- • Other protocol defined Inclusion/Exclusion criteria may apply.
