Abstract
BACKGROUND: NovoTTF-100A System is an FDA-approved treatment for recurrent glioblastoma (GBM) and is defined as a device of high unmet medical need in Japan. Subsequently, the device has been made available on a restricted case basis for compassionate use in Japan. Here we report initial experience with 10 patients treated at Tokyo Women's Medical University, Kashiwaba Neurosurgical Hospital and Japanese Red Cross Medical Center. METHODS: Using retrospective chart review, we analyzed patient demographics, tumor size, location, and treatment compliance with NovoTTF-100A System from the device log files. Duration of therapy was estimated using the Kaplan-Meier estimate. Adverse event frequency and severity was also evaluated. RESULTS: Ten (10) patients with supra-tentorial recurrent GBM were treated between July 8, 2013 and June 3, 2014 at 3 Japanese hospitals. 80% were male and 20% female. The median age was 41 years (range 32-66). The average baseline tumor burden was 13.3 cm2. 40% of patients had bi-hemispheric tumors and 30% left hemispheric tumors. The K-M median duration of therapy was 7.8 months. Average daily device compliance was 17.4 hours. This is consistent with prior global studies which have demonstrated average daily device compliance of 70-80%. The device was well-tolerated with no reported serious adverse events. The only device-related adverse events were mild skin irritation. CONCLUSIONS: NovoTTF-100A System was safe and well-tolerated in an initial cohort of Japanese patients with GBM. Device usage and compliance was consistent with that observed in non-Japanese patients.
