$NVCRPress releaseOct 1, 2026, 9:00 AM ETRead the release

Japan's MHLW approved Novocure's Optune Pax for adult patients with unresectable locally advanced pancreatic cancer, used concomitantly with gemcitabine and nab-paclitaxel. The approval is based on the Phase 3 PANOVA-3 trial, which met its primary endpoint with a statistically significant improvement in median overall survival versus chemotherapy alone. Optune Pax was previously approved by the FDA in February 2026 and received a CE Mark in June 2026; the Japan approval adds a third major market for the pancreatic cancer indication.
