Newly Diagnosed GBM

Designed to extend survival in ndGBM1, 4

Since 2005, EF-14 is the only positive phase 3 trial in GBM.19

The trial included 695 patients with newly diagnosed GBM1,3,20

Flowchart of treatment study structure for newly diagnosed GBM with Optune Gio, including surgery, radiation, and progression treatment options.

Efficacy endpoints1,20

  • Primary endpoint: PFS, assessed centrally
  • Powered secondary endpoint: OS
  • Additional secondary endpoints: PFS6, 1- and 2-year survival, QoL, radiological response rates

Key inclusion criteria1,3

  • Underwent maximal debulking surgery and radiotherapy concomitant with TMZ
  • KPS ≥70

Key exclusion criteria1

  • Progressive disease per Macdonald criteria, following concomitant chemoradiation
  • Implanted electronic medical devices
  • Significant comorbidities at baseline that would prevent maintenance TMZ treatment
  • Infratentorial tumor(s)

Optune Gio can be continued past first progression1

Give your newly diagnosed patients the best chance at extending survival1, 3

As part of your treatment approach, incorporating Optune Gio with other available options such as surgery, radiation, and TMZ can contribute to redefining your patients’ treatment results1,3

Based on EF-14, incorporating Optune Gio into your treatment paradigm may add nearly 5 months to median overall survival (P<0.001).1,3

In newly diagnosed GBM,

A post hoc analysis of the EF-14§ study demonstrated that Optune Gio + TMZ was associated with increased survival in elderly patients22

OS in patients 65 years and older

  • This post hoc subgroup analysis included data from all 134 patients 65 years of age and older in the intent-to-treat population and compared OS, PFS, and safety between the 2 treatment arms: Optune Gio + TMZ (n=89) vs TMZ alone (n=45)
  • Patient baseline characteristics and known prognostic factors were balanced between the 2 treatment groups
  • Median patient age and KPS were 69 years and 90, respectively
  • Survival rates for patients 65 years of age and older were consistent with the overall trial population

Optune Gio + TMZ in elderly patients showed no significant increase in AEs

  • No significant increase in systemic AEs in patients treated with Optune Gio + TMZ (46%) vs TMZ alone (40%)
  • SAEs were reported in 39% of patients treated with Optune Gio + TMZ and in 33% of patients treated with TMZ alone. None were considered related to treatment with Optune Gio
  • The rate of grade 1 or 2 medical device site reaction was 51% for Optune Gio + TMZ compared with 0% for TMZ alone, and severe (grade 3) skin involvement occurred in 2% of patients treated with Optune Gio + TMZ

Optune Gio + TMZ was also associated with improved PFS vs TMZ alone in elderly patients

  • Median PFS: 6.5 months vs 3.9 months; HR: 0.47 (95% CI, 0.30-0.74)

Consider Optune Gio as an option for your patients over 65

Efficacy in patients with biopsy only

In newly diagnosed GBM,

A post hoc analysis of the EF-14§ study showed Optune Gio + TMZ was associated with increased median OS vs TMZ alone in patients ineligible for surgical resection3

The EF-14 pivotal phase 3 trial included patients with newly diagnosed GBM who only had a biopsy3

Comparison table of surgical interventions for Optune Gio + TMZ versus TMZ alone, including biopsy, partial, and gross total resection.
  • The study protocol defined surgery as surgical resection to the extent safely feasible or biopsy3
  • In the EF-14 trial:
    • 13% of patients in each study arm only had a biopsy3
    • 3 patients treated with Optune Gio + TMZ and 1 patient in the TMZ alone group were included in the analysis at 48 months6

Patients with biopsy only are especially vulnerable to progression—help protect them with Optune Gio6

”Many people in the Optune [Gio] community remain active, working, biking, hunting, etc, while wearing the device, so it is possible to not allow it to be ‘invasive,’ but each of us has our own sensitivities, so the main thing is you make the choice that is right for you.”

 

—Caregiver (American Tumor Association forum)

Optune Gio + TMZ may give your patients the opportunity to extend survival without negatively impacting their daily activities, compared with TMZ alone

The flexibility to choose their treatment time

Patients may “bank hours”—wearing the device more on some days and less on others—as long as they average 75% of the month using the device.12

Graph illustrating daily use differences between Miriam and Kelvin throughout the week

Encourage a routine: Upfront, it can help to set a goal of 30, 60, or 90 days in which they commit to exploring their comfort zones

  • The recommended time for using Optune Gio is 18 hours a day
  • Kelvin and Miriam took different approaches to making Optune Gio work for them
  • Miriam wore Optune Gio extra hours over the weekend because she had a business trip midweek
  • Kelvin wore Optune Gio for roughly the same number of hours each day
  • Both patients averaged 18 hours/day over the course of the week shown

With Optune Gio, patients can control their GBM treatment on their terms

Optune Gio did not add systemic side effects during the EF-14 trial

There were no significant increases in serious AEs compared with TMZ alone, and no late-emerging serious AEs were seen in the 5-year follow-up1,3

Adverse events table for grade 3/4 side effects over 5 years, comparing Optune Gio + TMZ vs TMZ alone in common disorders.

The only device-related AEs from the clinical trial were skin related

  • Mild-to-moderate skin irritation, the most common device-related side effect with Optune Gio, was typically manageable, reversible, and did not result in treatment discontinuation26
  • The rate of grade 1/2 medical device site reaction was 52% for Optune Gio + TMZ compared with 0% for TMZ alone, and severe (grade 3) skin involvement occurred in 2% of patients treated with Optune Gio + TMZ3
  • Grade 3/4 AEs were well balanced between arms. None of the systemic grade 3/4 AEs were considered related to Optune Gio by any of the investigators1

The M3 approach to managing dAEs can help extend time on treatment12

While dermatologic AEs (dAEs) can be common for patients using Optune Gio, you can help maximize time on treatment by getting ahead of them with the M3 approach

Mitigate by prepping12,27:

  • Clean the scalp before shaving and make sure to clean the electric razor per the manufacturer’s guidelines after every shave
  • Apply mineral oil before shaving to cleanse the skin and help remove bacteria and scale

Monitor symptoms12

  • Tell your patient to report any redness, rash, or itching as soon as possible
  • Encourage patients to report and keep a photographic diary of any skin problems

Manage with proper treatment12

  • Depending on skin diagnosis, recommended treatments typically include topical antibiotics or topical corticosteroids

Indications For Use

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

 

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

 

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

 

Warnings and precautions

Optune Gio can only be prescribed by a healthcare provider that has completed the required certification training provided by Novocure (the device manufacturer).

 

Do not prescribe Optune Gio for patients that are pregnant, you think might be pregnant or are trying to get pregnant, as the safety and effectiveness of Optune Gio in these populations have not been established.

 

The most common (≥10%) adverse events involving Optune Gio in combination with temozolomide were thrombocytopenia, nausea, constipation, vomiting, fatigue, medical device site reaction, headache, convulsions, and depression.

 

The most common (≥10%) adverse events seen with Optune Gio monotherapy were medical device site reaction and headache.
The following adverse reactions were considered related to Optune Gio when used as monotherapy: medical device site reaction, headache, malaise, muscle twitching, fall, and skin ulcer.

 

Use of Optune Gio in patients with an inactive implanted medical device in the brain has not been studied for safety and effectiveness, and use of Optune Gio in these patients could lead to tissue damage or lower the chance of Optune Gio being effective.

 

If the patient has an underlying serious skin condition on the scalp, evaluate whether this may prevent or temporarily interfere with Optune Gio treatment.
