Nov 9 (Reuters) – Novocure said on Monday the US health regulator has declined to approve its device for ​patients whose lung cancer has spread ‌to the brain.

• The company had submitted an application seeking approval for Optune Mya — the device meant for adults with brain tumors from ‌non-small ​cell lung cancer who ⁠have already had stereotactic ⁠radiation, a precise form of radiation treatment

• The US Food and Drug Administration was unsure about how much clinical ​benefit the device could provide to patients, according to the company’s release

• The ⁠agency did not raise ⁠safety concerns, the cancer treatment ​device maker said

• Novocure had reported in ​2024 that a late-stage trial met its ‌main goal of delaying brain tumor growth in lung cancer patients, but preliminary results for overall survival did not reach ⁠statistical significance

• Optune Mya uses the company’s tumor treating fields technology, which delivers electric fields ⁠designed to ‌disrupt cancer cell growth

• Novocure ⁠said it was reviewing the ​FDA’s ‌feedback and plans to meet ​with the ⁠agency to see whether there are any options that would support the approval of its application without requiring additional clinical studies
