Red Journal Publishes Data Supporting Personalized Treatment Planning to Increase TTFields Efficacy for Patients with Glioblastoma
Novocure (NASDAQ: NVCR) announced today that a computational study analyzing the effect of transducer layout on Tumor Treating Fields, or TTFields, distribution has been published in the International Journal of Radiation Oncology • Biology • Physics, also known as the Red Journal. The study results suggest that customizing transducer array layouts based on tumor locations can significantly increase field strength within tumors.
The anti-mitotic effect of TTFields is dose-dependent starting at an electric field strength of 1 V/cm and increasing with increasing field intensity. Consistent with prior research, the average electric field induced in the published model exceeded the therapeutic threshold of 1 V/cm in all tumors. Field strength within a tumor did not correlate with its size or shape but was dependent on tumor location. Field strength always increased when the array layout was adapted according to the anatomic location of the tumor.
The full study can be accessed here.
Novocure offers a transducer array layout system, the NovoTAL System, allowing certified Optune prescribers to optimize TTFields therapy for each glioblastoma, or GBM, patient. The personalized transducer array layout maximizes the intensity of TTFields within a patient's tumor based on morphological measurements of the head, tumor size and location. With the NovoTAL system, healthcare providers who have been trained and certified can generate transducer array layout maps for their Optune patients as an office-based procedure.
About Tumor Treating Fields Therapy
Tumor Treating Fields (TTFields) therapy is delivered by a portable, non-invasive medical device designed for continuous use by patients. In vitro and in vivo studies have shown that TTFields therapy slows and reverses tumor growth by inhibiting mitosis, the process by which cells divide and replicate. TTFields therapy creates low intensity, alternating electric fields within a tumor that exert physical forces on electrically charged cellular components, preventing the normal mitotic process and causing cancer cell death.
In the United States, Optune is intended as a treatment for adult patients (22 years of age or older) with histologically-confirmed glioblastoma multiforme (GBM).
In the United States, Optune with temozolomide is indicated for the treatment of adult patients with newly diagnosed, supratentorial glioblastoma following maximal debulking surgery and completion of radiation therapy together with concomitant standard of care chemotherapy.
In the United States, for the treatment of recurrent GBM, Optune is indicated following histologically-or radiologically-confirmed recurrence in the supratentorial region of the brain after receiving chemotherapy. The device is intended to be used as a monotherapy, and is intended as an alternative to standard medical therapy for GBM after surgical and radiation options have been exhausted.
In the European Union, Optune is intended for the treatment of patients with newly diagnosed GBM, after surgery and radiotherapy with adjuvant temozolomide, concomitant to maintenance temozolomide. The treatment is intended for adult patients, 18 years of age or older, and should be started more than four weeks after surgery and radiation therapy with adjuvant temozolomide. Treatment may be given together with maintenance temozolomide and after maintenance temozolomide is stopped.
In the European Union, Optune is also intended for the treatment of patients with recurrent GBM who have progressed after surgery, radiotherapy and temozolomide treatment for their primary disease. The treatment is intended for adult patients, 18 years of age or older, and should be started more than 4 weeks after the latest surgery, radiation therapy or chemotherapy.
Patients should only use Optune under the supervision of a physician properly trained in use of the device. Full prescribing information is available at www.optune.com/safety or by calling toll free 1-855-281-9301 in the US or by email at supportEMEA@novocure.com in the European Union.
