Global Clinical Landscape & Future Outlook

The race for KLK5 therapeutics is intensifying. Major players are shifting focus from broad immunosuppressants and non-selective serine protease inhibitors to highly selective monoclonal antibodies and targeted biologics. In Netherton syndrome, hyperactive KLK5 due to SPINK5 mutation drives barrier dysfunction; recent advances include BridgeBio's BBP-361 entering Phase I/II trials. The next wave of R&D is expected to focus on dual kallikrein blockade (KLK5/KLK7), topical formulations to limit systemic exposure, and allosteric inhibitors that avoid active-site cross-reactivity. For competitive positioning, the key challenge remains achieving subfamily selectivity without disrupting global homeostatic networks.
