Celldex Inc.’s KIT inhibitor, barzolvolimab, which hit its phase II endpoints in late 2023, kicking off phase III development in chronic spontaneous urticaria, offered up some impressive long-term findings at the EAACI Congress 2025, including complete responses in patients for as long as seven months after the cessation of therapy, which analysts said could position the drug as a potentially best-in-class option.
THB-335 is an oral inhibitor of mast/stem cell growth factor receptor Kit (KIT), which regulates the activation and migration of mast cells, making it a relevant therapeutic target for inflammatory and allergic processes.
At the recent AAAAI/WAO meeting, Blueprint Medicines Corp. presented the in vitro and in vivo characterization of BLU-808, a selective inhibitor of wild-type KIT, a transmembrane receptor tyrosine kinase involved in mast cell activation, proliferation and chemotaxis.
The closely watched chronic spontaneous urticaria (CSU, or hives) space chalked more early stage KIT inhibitor data as Third Harmonic Bio Inc. rolled out results from the phase I single and multiple ascending-dose trial with THB-335 in healthy volunteers, along with plans to move the oral candidate into phase II development by the middle of 2025.
