First Patient Enrolled in RTOG Trial of Optune® together with Bevacizumab for Patients with Bevacizumab-Refractory Recurrent Glioblastoma

The RTOG 3503 phase 2 pilot trial is the first consortium study to test treatment with Optune

ST. HELIER, Jersey–(BUSINESS WIRE)– Novocure™ (NASDAQ: NVCR) announced today that the first patient has been enrolled in the RTOG Foundation’s phase 2 pilot trial testing Optune together with bevacizumab for patients with bevacizumab-refractory recurrent glioblastoma (GBM).

Optune is an FDA-approved Tumor Treating Fields (TTFields) delivery system for the treatment of newly diagnosed and recurrent GBM. In recurrent GBM, both Optune and bevacizumab are approved as monotherapies. The current trial intends to test the efficacy and safety of Optune in combination with bevacizumab for the treatment of patients with bevacizumab-refractory recurrent GBM.

“The results of this trial will provide additional information to the brain tumor research community on the safety and effectiveness of using Optune in combination with bevacizumab in patients with bevacizumab-refractory recurrent GBM,” said Dr. Manmeet Ahluwalia, Dean and Diane Miller Endowed Chair in NeuroOncology at Cleveland Clinic and Co-Principal Investigator of the trial. “These patients face a dismal prognosis and are in need of treatment options.”

The RTOG Foundation Study RTOG 3503 is planned to include 85 patients at 20 institutions in the United States. Patients must have a recurrence or progression of GBM or other grade IV glioma after being treated with bevacizumab. The trial will determine the efficacy of Optune together with bevacizumab measured by overall survival at six months. Additional endpoints include overall and progression-free survival from time of registration, response rates, and toxicities of bevacizumab with Optune.

“This is the first consortium study of TTFields, demonstrating the continued and mounting interest in Optune from the scientific community,” said Dr. Eilon Kirson, Chief Science Officer and Head of Research and Development at Novocure. “Our EF-11 phase 3 pivotal trial in recurrent GBM patients suggested that in a subgroup of patients who were refractory to bevacizumab Optune monotherapy led to an extension in survival versus chemotherapy. We are excited that RTOG is researching the potential benefit of Optune together with bevacizumab in this difficult-to-treat population of patients.”

“For 40 years, RTOG has conducted studies designed to improve the survival and quality of life of cancer patients,” said Dr. Jeffrey J. Raizer, Co-Founding-Director of the Northwestern Brain Tumor Institute and Co-Principal Investigator of the trial. “RTOG is excited to partner with Novocure on this important study, and I am pleased to be able to offer Optune to patients in this study.”

Treatment with TTFields is not approved in combination with bevacizumab for the treatment of patients with bevacizumab-refractory recurrent GBM by the U.S. Food and Drug Administration. The safety and effectiveness of TTFields in combination with bevacizumab for the treatment of patients with bevacizumab-refractory recurrent GBM has not been established.

The RTOG Foundation, Inc., a nonprofit research organization, is an international leader in conducting practice-changing clinical trials involving advanced radiotherapy techniques and their combination with new classes of anti-cancer biomarker driven therapies. RTOG Foundation is the successor to the Radiation Therapy Oncology Group, a 40-year participant in the cooperative group program funded by the National Cancer Institute (NCI). RTOG’s mission then and now is to improve the survival and quality of life of cancer patients. RTOG trials employ translational research strategies to identify patient subgroups that are at risk for failure with existing treatments and identify new treatment options for these patients. RTOG designs and conducts NCI-funded trials as a founding member of NRG Oncology and collaborates with industry partners to identify and test promising new agents through multisite private sector trials. This trial is funded entirely through corporate support from Novocure and has not been approved by the NCI.

Approved Indications

Optune is intended as a treatment for adult patients (22 years of age or older) with histologically-confirmed glioblastoma multiforme (GBM).

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.

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.

Important Safety Information

Contraindications: Do not use Optune if you have an active implanted medical device, a skull defect (such as, missing bone with no replacement), or bullet fragments. Use of Optune together with implanted electronic devices has not been tested and may theoretically lead to malfunctioning of the implanted device. Use of Optune together with skull defects or bullet fragments has not been tested and may possibly lead to tissue damage or render Optune ineffective.
