SION-638
Status
Phase OneTherapeutic Approach
Restore CFTR Protein
SION-638 is a corrector, a type of CFTR modulator designed to fix the defective CFTR protein so that it can move to the proper place on the cell surface. It aims to stabilize defective CFTR by targeting a specific location on the protein called nucleotide binding domain 1, or NBD1. Once the stabilized CFTR protein reaches the cell surface, it forms a channel to allow chloride and sodium (salt) to move in and out of the cell. This new, unique approach could eventually offer an alternative to currently approved modulators.
Status
A Phase 1 study to test the safety and tolerability of SION-638 in healthy volunteers was completed. Future studies are planned to evaluate SION-638 in people with CF who have the F508del CFTR mutation.
