Profile

Sionna Therapeutics is a clinical-stage biopharmaceutical company focused on developing small molecule medicines to treat cystic fibrosis by normalizing the function of the CFTR protein. The company specifically targets the nucleotide binding domain 1 (NBD1) to correct defects caused by the F508del mutation, which affects approximately 90% of cystic fibrosis patients. Their core value proposition lies in achieving near-normal CFTR function through novel NBD1 stabilizers that can be used as monotherapies or in combination with other modulators.

Competitive position

A clinical-stage innovator targeting the previously 'undruggable' NBD1 domain to differentiate from existing CFTR modulators.
