Kura Oncology is a clinical-stage

biopharmaceutical company committed to realizing the promise of precision medicines for the treatment of cancer. Kura s pipeline consists of two wholly-owned small molecule drug candidates that target cancer signaling pathways where there is a

strong scientific and clinical rationale to improve outcomes by identifying those patients most likely to benefit from treatment. Kura s most advanced drug candidate is tipifarnib, a potent, selective and orally bioavailable farnesyl

transferase inhibitor currently in a registration-directed trial in patients with recurrent or metastatic HRAS mutant head and neck squamous cell carcinoma (HNSCC). Kura s pipeline is also highlighted by

KO-539, a potentially first-in-class, potent and selective inhibitor of the menin-MLL protein-protein interaction currently in a

Phase 1/2A clinical trial in patients with relapsed/refractory AML.
