Novocure GmbH secured U.S. FDA approval for Optune Lua, a wearable device that delivers alternating electric fields or tumor treating fields that kill cancer cells. Indicated for use with PD-1/PD-L1 inhibitors or docetaxel in the second or subsequent line for the treatment of metastatic non-small-cell lung cancer following the failure of platinum-based regimens, the approval was driven by the significant improvement in overall survival rates seen in the LUNAR pivotal study for Optune Lua.
