NovoCure (NVCR) said Tuesday that the Optune Lua medical device has received a CE Mark to treat adults with metastatic non-small cell lung cancer who have progressed on or after a platinum-based treatment.

The approval covers the use of the medical device simultaneously with immune checkpoint inhibitors or docetaxel, the company said.

The portable device produces alternating electric fields, called Tumor Treating Fields, which are delivered via wearable arrays, NovoCure said.

NovoCure said it has started the local registration requirements for the device in Germany and is getting ready for launch in the coming weeks.

Optune Lua was also cleared by the US Food and Drug Administration in October, the company said.

NovoCure shares were 4.1% higher in recent trading.
