Novocure Announces Preliminary 2015 Operating Statistics

ST. HELIER, Jersey

Novocure (NASDAQ: NVCR), a commercial stage oncology company pioneering a novel therapy for solid tumors, will provide a business update as well as its preliminary operating statistics for the fourth quarter and full year 2015 at the 34^th Annual J.P. Morgan Healthcare Conference. The fourth quarter of 2015 was marked by substantial growth versus the prior quarter driven primarily by the FDA approval for Optune in newly diagnosed glioblastoma on October 5, 2015. This growth was largely achieved prior to the peer-reviewed publication of the successful EF-14 newly diagnosed glioblastoma phase 3 clinical trial in the Journal of the American Medical Association (JAMA) on December 15, 2015.

“The fourth quarter of 2015 was an outstanding quarter for Novocure and the momentum from 2015 positions us for another year of strong growth in 2016,” said Asaf Danziger, Novocure’s Chief Executive Officer. “The FDA approval of Optune for newly diagnosed glioblastoma was a key catalyst of our commercial business and we enter 2016 focused on communicating our superior outcomes in glioblastoma as we work to transform the standard of care for this disease.”

• 1,774 prescriptions were received in the year, an increase of 151% versus the prior year. 1,607 of the prescriptions were received in the U.S. and 167 were received outside of the U.S., primarily in Europe.

About Tumor Treating Fields (TTFields)

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.

Approved Indications

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 supra-tentorial 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 4 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.

In Japan, Optune (the NovoTTF-100A System) is approved for the treatment of adult patients with recurrent supra-tentorial glioblastoma after all possible surgical and radiation therapy options have been exhausted.

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.
