Testing new combination medications for cystic fibrosis safety

This is an early-stage safety study testing SION-451 combined with two complementary medications (SION-2222 and SION-109) that are being developed to treat cystic fibrosis. Researchers want to understand how the medication works in the body and whether it causes any side effects when healthy people take it. This helps determine if the treatment is safe enough to test in people with cystic fibrosis.

Cystic fibrosis is a serious genetic disease that damages the lungs and digestive system. Researchers are developing these new medications to address the underlying problems in CF, and this study is the first step to make sure the treatment is safe before testing it in patients who actually have the disease.
