Inhibrx Biosciences, Inc. has surged nearly 40% amid rumors of Big Pharma interest in joint spinoffs of INBRX-106 and possibly a second asset. Ozekibart's Phase 2 data in chondrosarcoma showed a 52% risk reduction in progression or death, positioning INBX as a first-mover in an unmet oncology market. INBRX-106, in combination with Keytruda, is advancing through Phase 2/3 trials, with key data readouts and potential spinoff partnerships as near-term catalysts.
