Data identify nuclear PD-L1 as a previously unaddressed driver of immunotherapy resistance and metastatic progression SYDNEY, Jan. 30, 2026 /PRNewswire/ -- Kazia Therapeutics (NASDAQ: KZIA), an oncology-focused pharmaceutical company developing novel therapies for difficult-to-treat cancers, today announced compelling preclinical and translational data supporting the development of NDL2, a potentially first-in-class protein degrader that is designed to selectively eliminate nuclear PD-L1, a previously unrecognized intracellular driver of immunotherapy resistance and metastatic progression that is not addressed by currently approved PD-1/PD-L1 antibodies. Across multiple preclinical models and patient-derived samples, NDL2 demonstrated reversal of immune exhaustion, suppression of metastatic biology, and enhanced anti-tumor activity, including in combination with anti-PD-1 therapy.
