Novocure Announces FDA Approval of IDE Supplement for Phase 3 Pivotal LUNAR Trial of Tumor Treating Fields in Non-Small Cell Lung Cancer

IDE supplement incorporates recommended changes from the interim analysis of the LUNAR trial conducted by an independent data monitoring committee

ST. HELIER, Jersey–(BUSINESS WIRE)–#lcsm–Novocure (NASDAQ: NVCR) today announced the U.S. Food and Drug Administration (FDA) has approved the company’s Investigational Device Exemption (IDE) supplement, reducing the enrollment requirement for its LUNAR trial to 276 patients with 12 months follow-up. LUNAR is a phase 3 pivotal trial testing the effectiveness of Tumor Treating Fields in combination with immune checkpoint inhibitors or docetaxel versus immune checkpoint inhibitors or docetaxel alone for patients with stage 4 NSCLC who progressed during or after platinum-based therapy.

The IDE supplement incorporates recommended changes from the interim analysis of the LUNAR trial conducted by an independent data monitoring committee (DMC). After review of the interim analysis report earlier this year, the DMC concluded that the LUNAR trial should continue with no evidence of increased systemic toxicity. The DMC also stated that it is likely unnecessary and possibly unethical for patients randomized to the control arm of the trial to continue accrual according to the original protocol. The DMC recommended a reduced sample size of approximately 276 patients with 12 months follow-up which it believes will provide sufficient overall power for both primary and secondary endpoints. The DMC recommended no other changes to the trial design. Novocure remains blinded to all data.

“We are very pleased with the FDA approval of the DMC’s recommended protocol adjustments and are grateful for the FDA’s prompt review,” said Asaf Danziger, Novocure’s CEO. “We now anticipate last patient enrollment in the LUNAR trial in the fourth quarter of 2021 with final data available in 2022 and look forward to sharing data from the LUNAR trial as quickly as possible.”

About LUNAR

LUNAR is a phase 3 pivotal trial testing the effectiveness of TTFields in combination with immune checkpoint inhibitors or docetaxel versus immune checkpoint inhibitors or docetaxel alone for patients with stage 4 NSCLC who progressed during or after platinum-based therapy. It is estimated that approximately 46,000 patients receive second-line treatment for stage 4 NSCLC each year in the U.S. The primary endpoint is superior overall survival of patients treated with TTFields plus immune checkpoint inhibitors or docetaxel versus immune checkpoint inhibitors or docetaxel alone. TTFields is intended principally for use in combination with other standard-of-care treatments, and LUNAR was designed to generate data that contemplates multiple outcomes, all of which Novocure believes will be clinically meaningful.

About Tumor Treating Fields

Tumor Treating Fields, or TTFields, are electric fields that disrupt cancer cell division.

When cancer develops, rapid and uncontrolled division of unhealthy cells occurs. Electrically charged proteins within the cell are critical for cell division, making the rapidly dividing cancer cells vulnerable to electrical interference. All cells are surrounded by a bilipid membrane, which separates the interior of the cell, or cytoplasm, from the space around it. This membrane prevents low frequency electric fields from entering the cell. TTFields, however, have a unique frequency range, between 100 to 500 kHz, enabling the electric fields to penetrate the cancer cell membrane. As healthy cells differ from cancer cells in their division rate, geometry and electric properties, the frequency of TTFields can be tuned to specifically affect the cancer cells while leaving healthy cells mostly unaffected.

Whether cells are healthy or cancerous, cell division, or mitosis, is the same. When mitosis starts, charged proteins within the cell, or microtubules, form the mitotic spindle. The spindle is built on electric interaction between its building blocks. During division, the mitotic spindle segregates the chromosomes, pulling them in opposite directions. As the daughter cells begin to form, electrically polarized molecules migrate towards the midline to make up the mitotic cleavage furrow. The furrow contracts and the two daughter cells separate. TTFields can interfere with these conditions. When TTFields are present in a dividing cancer cell, they cause the electrically charged proteins to align with the directional forces applied by the field, thus preventing the mitotic spindle from forming. Electrical forces also interrupt the migration of key proteins to the cell midline, disrupting the formation of the mitotic cleavage furrow. Interfering with these key processes disrupts mitosis and can lead to cell death.

TTFields is intended principally for use together with other standard-of-care cancer treatments. There is a growing body of evidence that supports TTFields’ broad applicability with certain other cancer therapies, including radiation therapy, certain chemotherapies and certain immunotherapies. In clinical research and commercial experience to date, TTFields has exhibited no systemic toxicity, with mild to moderate skin irritation being the most common side effect.

Fundamental scientific research extends across two decades and, in all preclinical research to date, TTFields has demonstrated a consistent anti-mitotic effect. The TTFields global development program includes a broad range of clinical trials across all phases, included four phase 3 pivotal trials in a variety of tumor types. To date, more than 18,000 patients have been treated with TTFields.

Use of Tumor Treating Fields for the treatment of NSCLC is investigational only.
