Clinical Trial Summary

This is a non-randomized, concurrent control study, designed to confirm that the efficacy of the NovoTTF-100A System in patients with recurrent GBM treated in a real life settings following approval is comparable to that of BSC chemotherapy patients. The device is a portable, battery operated device that was approved for the treatment of adult patients (22 years of age or older) with histologically-confirmed glioblastoma multiforme (GBM), 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.

Description:

PAST CLINICAL EXPERIENCE:

The effect of the electric fields generated by the NovoTTF-100A device (TTFields, TTF) has been tested in a large prospective, randomized trial, in 237 recurrent GBM patients. The outcome of subjects treated with the NovoTTF-100A device was compared to those treated with an effective best standard of care chemotherapy (including bevacizumab). NovoTTF-100A subjects had comparable overall survival to subjects receiving the best available chemotherapy in the US today. Similar results showing comparability of NovoTTF-100A to BSC chemotherapy were seen in all secondary endpoints.

Recurrent GBM patients treated with the NovoTTF-100A device in this trial experienced fewer side effects in general, significantly fewer treatment related side effects, and significantly lower gastrointestinal, hematological and infectious adverse events compared to controls. The only device-related adverse events seen were a mild to moderate skin irritation beneath the device electrodes. Finally, quality of life measures were better in NovoTTF-100A subjects as a group when compared to subjects receiving effective best standard of care chemotherapy.

DESCRIPTION OF THE TRIAL:

Patients with GBM whose disease has first recurred despite standard treatment (Surgery, radiation therapy, Temozolomide treatment) and meet all of the requirements for participation in the study will be recruited to one of two groups based on patient preference alone:

1. Treatment with the NovoTTF-100A device, or

2. Treatment with the best standard of care practiced at each of the participating centers.

If recruited to the best standard of care group, patients will receive a chemotherapeutic agent chosen based on their prior treatments and the standard of care practiced at each treating center.

If recruited to the NovoTTF-100A group, the patients will be treated continuously until tumor progression. NovoTTF-100A treatment will consist of wearing four electrically insulated electrodes on the head. Electrode placement will require shaving of the scalp before treatment. Patients will continue treatment at home where they can maintain their regular daily routine.

During the trial, regardless of whether assigned to the NovoTTF-100A treatment group or the best standard of care group, patients will need to return once every month the hospital outpatient clinics where they will be examined by a physician. These routine visits will continue for as long as the patient's disease is not progressing.

During the visits to the clinic patients will be examined physically and neurologically, as well as fill in neuro-cognitive questionnaires. Adverse events data will be collected from all patients.. After this follow up plan, patients will be contacted once per month by telephone to answer basic questions about their health status.

SCIENTIFIC BACKGROUND:

TTFields are alternating electric fields of low intensity. This means that they change their direction repetitively many times a second. Since they change direction very rapidly (200 thousand times a second), they do not cause muscles to twitch, nor do they have any effects on other electrically activated tissues in the body (brain, nerves and heart). Since the intensities of TTFields in the body are very low, they do not cause heating.

The breakthrough finding made by NovoCure was that finely tuned alternating fields of very low intensity, now termed TTFields (Tumor Treating Fields), cause a significant slowing in the growth of cancer cells. Due to the unique geometric shape of cancer cells when they are multiplying, TTFields cause the building blocks of these cells to move and pile up in such a way that the cells physically explode. In addition, cancer cells also contain miniature building blocks which act as tiny motors in moving essential parts of the cells from place to place. TTFields cause these tiny motors to fall apart since they have a special type of electric charge.

As a result of these two effects, cancer tumor growth is slowed and can even reverse after continuous exposure to TTFields.

Other cells in the body (normal healthy tissues) are affected much less than cancer cells since they multiply at a much slower rate if at all. In addition TTFields can be directed to a certain part of the body, leaving sensitive areas out of their reach.

In conclusion, TTField hold the promise of serving as a brand new cancer treatment with very few side effects and promising affectivity in slowing or reversing this disease.
