‘Out-of-the-Box’ Approach Plus Temozolomide Extends Survival in Glioblastoma

Excerpt:

“Using a novel approach called tumor-treating fields—which involves the delivery of low-intensity electric fields to the brain by a patient-operated device—along with standard-of-care temozolomide therapy improved overall survival and progression-free survival vs temozolomide alone in patients with glioblastoma, according to the final results of a phase III trial presented at the 2017 American Association for Cancer Research (AACR) Annual Meeting. Patients treated with tumor-treating fields plus temozolomide had a 37% reduced risk of death compared with those randomized to receive temozolomide alone.”

TTFields Significantly Improve Survival in GBM

Excerpt:

“A landmark analysis of findings from the EF-14 trial testing the efficacy and safety of tumor treating fields (TTFields) for the treatment of patients with glioblastoma multiforme (GBM) has found that the risk of death was reduced by 37% and overall survival (OS) was extended by a median of 5 months with the use of the device.

“Two-, 3-, 4-, and 5-year overall and progression-free survival (PFS) rates for patients who received TTFields with adjuvant temozolomide were significantly improved over patients who received temozolomide alone, reported Roger Stupp, MD, professor of neurological surgery at Northwestern University Feinberg School of Medicine and associate director for strategic initiatives at the Robert H. Lurie Comprehensive Cancer Center.”

Brain Cancer Survival Improves with Novel Electrical Device, Data Suggest

Excerpt:

“A wearable medical device that delivers electrical fields through the scalp helped to extend the survival of patients with lethal brain tumors, according to data presented Sunday.

“In a study involving major medical centers in the United States and abroad, the novel treatment was used to administer alternating, low-intensity ‘tumor-treating fields’ to newly diagnosed glioblastoma patients who also were getting chemotherapy. Such electrical fields may block the division of cancer cells and cause their demise, according to Roger Stupp, the study’s lead investigator and a neuro-oncologist at the Northwestern University Feinberg School of Medicine.”

New Study Aims to Extend TTFields Beyond Grade IV Brain Cancer Domain

Excerpt:

“The use of tumor treating fields (TTFields) as a treatment for patients with brain tumors has, thus far, largely been focused on in glioblastoma, but an upcoming trial aims to expand the use of the device to the grade III patient population, says Daniel O’Connell, MD.

“Currently, the device is only FDA approved for use in grade IV brain tumors, but O’Connell, a neuro-oncologist at UCLA’s David Geffen School of Medicine, anticipates the FDA will grant its approval for use in grade III tumors within the next 2 to 3 months.”

Preliminary Phase 2 Data Demonstrate Tumor Treating Fields Is Safe In Patients With Brain Metastases Originating From Non-Small Cell Lung Cancer

“Preliminary data from COMET, a phase 2 randomized trial sponsored by Novocure (NASDAQ: NVCR), show that the use of Tumor Treating Fields (TTFields) therapy is safe in the treatment of brain metastases originating from non-small cell lung cancer (NSCLC). The results of a preliminary analysis of the ongoing European study were presented Nov. 20 at the 20 th Annual Society for Neuro-Oncology Meeting in San Antonio.

“The preliminary analysis of the randomized COMET trial included 17 patients, six of whom were treated with TTFields plus supportive care and 11 of whom received supportive care alone, following stereotactic radiosurgery with or without surgical resection of the brain metastases. Patients treated with TTFields plus supportive care received TTFields applied to the brain at the specific frequency of 150 kHz, which has been shown in preclinical studies to be the optimal frequency for inhibiting mitosis of NSCLC cells. In both arms of the study, a total of 26 adverse events were reported, most of which stemmed from the underlying NSCLC. A single event, mild dermatitis, was the only complication linked to TTFields therapy. No serious adverse events related to TTFields therapy were reported.”
