Novocure announced that the final patient has been enrolled in phase 3 pivotal INNOVATE-3 trial evaluating the efficacy of Tumor Treating Fields (TTFields) together with paclitaxel for treatment of patients with platinum-resistant ovarian cancer. Following the completion of enrollment, an independent Data Monitoring Committee (DMC) will conduct the pre-specified interim analysis pursuant to the trial protocol. Final data from the INNOVATE-3 trial is anticipated in 2023. INNOVATE-3 is a randomized, open-label study which was designed to enroll 540 adult patients with recurrent, platinum-resist ovarian cancer. Patients have been randomized to receive either weekly paclitaxel alone or weekly paclitaxel concomitant with TTFields tuned to 200 kHz until progression. The primary endpoint is overall survival. Secondary endpoints include progression free survival, objective response rate, severity and frequency of adverse events, time to undisputable deterioration in health-related quality of life or death, and quality of life. The European Network for Gynecological Oncological Trials (ENGOT) and The GOG Foundation Inc. collaborated with Novocure on the design and facilitation of this trial. In the U.S., ovarian cancer ranks fifth in cancer deaths among women, with approximately 24,000 women diagnosed each year. Ovarian cancer incidence increases with age, and the median age at time of diagnosis is 63 years old. Physicians use different combinations of surgery and pharmacological therapies to treat ovarian cancer, depending on the stage of the disease. Surgery is usually used in early stages of the disease and is usually combined with chemotherapy, including paclitaxel and platinum-based chemotherapy. Unfortunately, the majority of patients are diagnosed at an advanced stage when the cancer has spread outside of the ovaries to include regional tissue involvement and/or metastases. Platinum-based chemotherapy remains part of the standard of care in advanced ovarian cancer, but most patients with advanced ovarian cancer will have tumor progression or, more commonly, recurrence. Almost all patients with recurrent disease ultimately develop platinum resistance, and the prognosis for this population remains poor. 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.
