Health economics and outcomes research showed post-Stupp therapeutic developments, including TTFields, significantly increase overall survival in a large commercially insured population
The largest safety dataset to date of more than 23,000 patients reinforced that TTFields therapy is well-tolerated in patients with high-grade gliomas
Novocure (NASDAQ: NVCR) today announced 25 abstracts on Tumor Treating Fields (TTFields) therapy will be featured at the Society for Neuro-Oncology (SNO) 2022 Annual Meeting from Nov. 16 to Nov. 20 in Tampa. The presentations cover a broad range of topics, including TTFields’ multimodal mechanism of action, safety and tolerability, and health economics and outcomes research (HEOR).
New research in HEOR includes an analysis by a coalition of researchers at Central Brain Tumor Registry of the United States (CBTRUS), Duke University and the National Cancer Institute that utilized commercial claims and population-based datasets to better understand potential treatment factors associated with improved survival for glioblastoma (GBM) (Corey Neff, M.P.H., Department of Neurosurgery, Duke University School of Medicine in Durham, North Carolina, et al.) The presentation, “Improvements in survival for glioblastoma in the post-Stupp protocol era,” showed that survival in GBM has continued to improve over time in the post-Stupp protocol era, which may be due to developments of new therapeutic approaches. The analysis showed post-Stupp therapeutic developments, including TTFields, significantly increase overall survival in the commercially insured population. Of the 19,414 identified adult patients with GBM, 3,061 used TTFields therapy. These patients experienced an extended median overall survival compared to patients who were not treated with TTFields (17.6 months versus 13.1 months, respectively; hazard ratio: 0.77; P<0.001).
A presentation by Maciej M. Mrugala, M.D., Ph.D., M.P.H., Director of the Neuro-Oncology Program at the Mayo Clinic College of Medicine and Science in Phoenix, analyzed post-market safety data from more than 23,000 high-grade glioma patients who received TTFields therapy in the last decade, representing the largest safety dataset to date. These global real-world data reinforced the findings from our EF-14 phase 3 pivotal study that TTFields therapy is well-tolerated in GBM patients, with no new safety signals identified. There were no observed differences by type of GBM diagnoses and by age subgroups. These data are consistent with previous findings in that TTFields therapy is not associated with added systemic toxicity; localized skin irritation is the most common adverse event and can be managed with appropriate prophylaxis and treatment strategies.
A presentation highlighting TTFields therapy as a treatment for newly diagnosed GBM includes the first results of the PriCoTTF phase 1/2 study, which met its primary endpoint demonstrating the safety and tolerability of TTFields concomitant with radiotherapy, presented by Sied Kebir, M.D., Deputy Head of the Division of Clinical Neurooncology at University Medicine Essen in Germany.
Josef Vymazal, M.D., Deputy Director of Na Homolce Hospital in Prague, will present data from 18 years of clinical practice experience with newly diagnosed GBM patients. Patients who received TTFields therapy demonstrated improvements in progression free survival and overall survival compared to controls (hazard ratio: 0.55, P=0.006; and 0.61, P=0.027 respectively). This is one of several extensive studies assessing survival outcomes in newly diagnosed GBM patients treated with TTFields therapy conducted at a single center to date.
“We are honored and proud of the volume and depth of TTFields research featured at the SNO 2022 Annual Meeting,” said Frank Leonard, President of Novocure’s U.S. CNS (central nervous system) Cancers Franchise. “Over the last 15 years, SNO has been an important meeting for Novocure as Tumor Treating Fields therapy has become ingrained within the neuro-oncology community and as our science continues to evolve. We look forward to gathering and participating in this essential scientific exchange for the advancement of neuro-oncology.”
All poster presentations will occur from 7:30 p.m. to 9:30 p.m. EST Friday, Nov. 18, in West/Central Hall.

About Tumor Treating Fields Therapy
Tumor Treating Fields (TTFields) are electric fields that exert physical forces to kill cancer cells via a variety of mechanisms. TTFields do not significantly affect healthy cells because they have different properties (including division rate, morphology, and electrical properties) than cancer cells. The multiple, distinct mechanisms of TTFields therapy work together to selectively target and kill cancer cells. Due to its multimechanistic actions, TTFields therapy can be added to cancer treatment modalities in approved indications and demonstrates enhanced effects across solid tumor types when used with chemotherapy, radiotherapy, immune checkpoint inhibition, or PARP inhibition in preclinical models. TTFields therapy provides clinical versatility that has the potential to help address treatment challenges across a range of solid tumors.
