“While there have been significant advances in targeted treatments for lung cancer, little progress has been made specifically for patients with squamous lung cancer. In addition, we know that patients with lung cancers that harbor mutations in the NRF2/KEAP1 pathway typically have poorer outcomes than those whose tumors do not have these mutations,” said Susan Molineaux, chief executive officer of Calithera. “This Fast Track designation allows for a variety of benefits, including the possibility of priority review of sapanisertib as we seek to provide a first-in-class treatment option that may help address the major unmet need in this patient population.”
