“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.”
