Global Clinical Landscape & Future Outlook

The therapeutic landscape for CFTR del F508 has been transformed by triple-combination modulators (e.g., elexacaftor/tezacaftor/ivacaftor), yet significant unmet need persists for patients with minimal function mutations and those requiring improved pulmonary function restoration. The race is intensifying toward next-generation correctors with superior ER-folding rescue efficiency and novel mechanisms targeting protein degradation pathways (e.g., premature termination codon readthrough, chaperone modulation). As first-generation therapies mature, the next wave of R&D is targeting genetic therapies (mRNA delivery, gene editing) and personalized corrector cocktails requiring precise mutant-specific assays. Emerging modalities like CRISPR-based gene editing and mRNA delivery aim to address underlying protein misfolding more permanently, while combination therapies with ENaC inhibitors and TMEM16A activators are gaining traction.
