First new therapy in nearly 30 years delivers survival benefit using innovative electric field technology
The U.S. Food and Drug Administration has approved Novocure’s (NVCR) Optune Pax® for the treatment of adults with locally advanced pancreatic cancer, marking a historic advancement in a field that has seen limited innovation for nearly three decades. The approval, announced Wednesday, positions Novocure (NVCR) at the forefront of a new treatment paradigm and sent the company’s shares sharply higher, reflecting investor optimism about its commercial potential.
Optune Pax represents a fundamentally different approach to cancer therapy. Unlike traditional chemotherapy or immunotherapy, the device uses Tumor Treating Fields (TTFields)—alternating electric fields delivered through wearable arrays—to disrupt cancer cell division. This biophysical mechanism selectively targets tumor cells while minimizing damage to healthy tissue, offering a promising alternative in a disease historically resistant to conventional treatments.
The FDA’s decision was supported by data from the Phase 3 PANOVA-3 trial, which enrolled 571 patients and evaluated Optune Pax in combination with standard chemotherapy agents gemcitabine and nab-paclitaxel. The study demonstrated a statistically significant improvement in overall survival, the trial’s primary endpoint. Patients treated with Optune Pax achieved a median overall survival of 16.2 months compared to 14.2 months for those receiving chemotherapy alone. Among patients who adhered more closely to the treatment protocol, survival extended even further to 18.3 months versus 15.1 months.
Equally important, Optune Pax significantly delayed disease-related pain progression—a critical factor in maintaining quality of life for pancreatic cancer patients. The median time to pain progression increased to 15.2 months compared to 9.1 months in the control group, representing a substantial improvement in patient comfort and functional well-being.
Notably, the therapy did not introduce significant additional systemic toxicity, with most adverse effects limited to manageable skin irritation at the device application sites. This favorable safety profile enhances its potential for widespread clinical adoption.
Pancreatic cancer remains one of the deadliest malignancies, with limited treatment options and historically poor survival rates. Novocure CEO Frank Leonard described the approval as a milestone not only for the company but for the broader medical community. With Optune Pax now approved, Novocure is poised to redefine treatment standards and capture a meaningful share of the rapidly evolving oncology market while offering renewed hope to patients facing this devastating disease.
