Instil Bio and ImmuneOnco unwind AXN-2510 pact as development stops
Instil Bio's subsidiary, Axion Bio, has discontinued clinical development of AXN-2510 and terminated its license and collaboration agreement with ImmuneOnco for AXN-2510 and AXN-27M. This decision leads to all rights for AXN-2510 outside Greater China reverting to ImmuneOnco, with Axion retaining a limited license to wind down existing clinical activities. This marks a significant shift from previous updates which highlighted AXN-2510 as a key clinical asset, prompting investors to focus on Instil Bio's reallocation of R&D resources and future pipeline developments.
