Patients treated with Optune® together with temozolomide demonstrated
a significant increase in progression free and overall survival compared
to patients treated with temozolomide alone

EF-14 patients treated with Optune together with temozolomide
experienced a 70 percent improvement in survival rate at four years
compared to patients treated with temozolomide alone

ST. HELIER, Jersey–(BUSINESS WIRE)– Novocure (NASDAQ:NVCR) announced today that a long-term analysis of the
full trial cohort from its phase 3 pivotal EF-14 trial of Optune® in
combination with temozolomide for the treatment of newly diagnosed
glioblastoma (GBM) confirmed the superior survival results seen at
interim analysis. The long-term analysis demonstrated superior two-,
three- and four-year survival of patients treated with Optune together
with temozolomide compared to temozolomide alone. The interim analysis
results – published in the Journal of the American Medical
Association (JAMA)
1 in December 2015 – showed
significant extension of both progression free and overall survival in
newly diagnosed GBM patients receiving Optune with temozolomide compared
to temozolomide alone.

EF-14 Principal Investigator Roger Stupp, M.D., Professor at the
University of Zurich and Director of Department of Oncology at the
Zurich University Hospital, Zurich, Switzerland, will present these late
breaking results at the 21st Annual Scientific Meeting of the
Society for Neuro-Oncology (SNO) on Nov. 18, in Scottsdale, Arizona.

“The analysis of the full dataset confirms the improvement in both
progression free and overall survival we saw in the trial’s interim
analysis, and demonstrates superior long-term survival,” Dr. Stupp said.
“These mature results further validate Optune as a standard of care
treatment option for glioblastoma, providing patients with a therapy
that can extend their survival while maintaining their quality of life.”

“We are excited that Novocure’s long-term analysis of the EF-14 trial
confirms the interim analysis results of superior overall and
progression free survival, while providing new data on potential
long-term survival benefits for newly diagnosed GBM patients,” said
Elizabeth M. Wilson, President and CEO of the American Brain Tumor
Association. “GBM patients need better treatment options, and it is a
great day when new evidence shows that we are making progress in
treating this disease.”

The long-term analysis of all patients (n=695) shows that:

  • Patients treated with Optune together with temozolomide demonstrated a
    significant increase in median progression free survival (PFS)
    compared to temozolomide alone (median PFS of 6.7 months versus 4.0
    months, respectively, hazard ratio=0.63, p=0.00005).
  • Patients treated with Optune together with temozolomide demonstrated a
    significant increase in median overall survival (OS) compared to
    temozolomide alone (median OS from randomization of 20.8 months versus
    16.0 months, respectively, hazard ratio=0.65, p=0.0006)
  • The percentage of patients alive at two years in the Optune together
    with temozolomide arm was 43 percent compared to 30 percent in the
    temozolomide alone arm, a 43% increase in the chance of living two
    years.
  • The percentage of patients alive at four years in the Optune together
    with temozolomide arm was 17 percent compared to 10 percent in the
    temozolomide alone arm, a 70% increase in the chance of living four
    years.
  • Consistent with the interim analysis, the OS and PFS benefit of Optune
    together with temozolomide compared to temozolomide alone was seen
    across all patient subgroups tracked in the EF-14 trial, including
    patient age, performance status and tumor genetics.
  • The safety profile in the long-term analysis was consistent with the
    interim analysis of the EF-14 trial.

“The long-term analysis further supports our data showing that Optune
together with temozolomide is a better treatment option for newly
diagnosed GBM patients compared to temozolomide alone,” said Asaf
Danziger, Novocure’s CEO. “We believe these results will give health
care providers further confidence in our therapy and transform the
standard of care in newly diagnosed GBM. Our priority is to improve the
lives of GBM patients, and we believe these results will help us to
accomplish our mission.”

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 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.

Do not use Optune if you are known to be sensitive to conductive
hydrogels. In this case, skin contact with the gel used with Optune may
commonly cause increased redness and itching, and rarely may even lead
to severe allergic reactions such as shock and respiratory failure.
