NovoCure's Tumor Treating Fields Boost One-Year And Pain-Free Survival In Pancreatic Cancer Trial

Core Insights - Zai Lab Limited and NovoCure Limited presented additional data from the Phase 3 PANOVA-3 trial of Tumor Treating Fields (TTFields) therapy for pancreatic cancer at the 2025 American Society of Clinical Oncology Annual Meeting [1] Group 1: Trial Overview - The Phase 3 PANOVA-3 trial evaluated TTFields therapy in combination with gemcitabine and nab-paclitaxel as a first-line treatment for unresectable, locally advanced pancreatic adenocarcinoma compared to gemcitabine and nab-paclitaxel alone [2] Group 2: Primary Endpoint Results - The trial met its primary endpoint, showing a statistically significant improvement in median overall survival (mOS) for patients treated with TTFields [3] - In the intent-to-treat population, patients receiving TTFields therapy had an mOS of 16.2 months compared to 14.2 months for those treated with gemcitabine and nab-paclitaxel alone, representing a statistically significant 2.0-month improvement [4] Group 3: Secondary Endpoint Results - The one-year survival rate for the TTFields group was 68.1%, significantly higher than the 60.2% for the control group [5] - Patients treated with TTFields had a median pain-free survival of 15.2 months compared to 9.1 months in the control group, indicating a statistically significant 6.1-month extension in pain-free survival [6] - No statistically significant differences were observed in additional secondary outcome measures such as progression-free survival and tumor resectability rate between the two treatment arms [7] Group 4: Safety Profile - TTFields therapy was well-tolerated, with no new safety signals observed, and safety outcomes were consistent with prior clinical studies [8] - Mild to moderate skin adverse events were the most common device-related adverse events [8]
