Global Clinical Landscape & Future Outlook

The race for HSP90 therapeutics is intensifying, with major players shifting focus from traditional pan-HSP90 inhibitors to isoform-selective molecules and chaperone-mediated degraders (PROTACs). As first-generation pan-inhibitors faced clinical hurdles due to dose-limiting toxicities (such as ocular and hepatotoxicity), the next wave of R&D is targeting specific cytosolic isoforms (HSP90AA1 vs. HSP90AB1) or utilizing HSP90-binding moieties to direct targeted protein degradation.
