Global Clinical Landscape & Future Outlook

The race for CALR therapeutics is intensifying, with major players shifting focus from generic JAK inhibitors to mutant-specific CALR-MPL disruptors and mutant-specific monoclonal antibodies. As first-generation JAK inhibitors (ruxolitinib, fedratinib) provide symptomatic relief but fail to address the driver mutation, the next wave of R&D is targeting the CALR-MPL protein-protein interaction (PPI) , mutant-specific neoantigens for vaccine development, and the intersection of CALR as an "eat me" signal with immune checkpoint modulation.

In the immuno-oncology space, surface-exposed CALR (ecto-CALR) serves as the primary "eat me" signal for immunogenic cell death (ICD). Drug development here focuses on CALR exposure inducers, anti-CALR antibody-drug conjugates, and bispecific modalities (e.g., CALR × CD47) to enhance tumor immunogenicity and overcome CD47-mediated immune evasion.
