Novocure Reports Positive Top-line Results from STELLAR Phase 2 Pilot Trial in Mesothelioma

Final STELLAR data exceeded the results of the interim analysis for all efficacy endpoints

Novocure plans to submit a Humanitarian Device Exemption application to the FDA for approval

ST. HELIER, Jersey–(BUSINESS WIRE)– Novocure (NASDAQ: NVCR) announced today positive top-line results from its STELLAR phase 2 pilot trial in mesothelioma demonstrating clinically meaningful improvements in overall survival and progression free survival among patients who received Tumor Treating Fields plus standard of care chemotherapy, pemetrexed and cisplatin or carboplatin, compared to historical control data of patients who received standard of care chemotherapy alone.

The final data exceeded the results of the interim analysis presented in December 2016 at the International Association for the Study of Lung Cancer (IASLC) 17th World Conference on Lung Cancer for all efficacy endpoints. No device-related serious adverse events were reported. Novocure will submit the full data for presentation at an upcoming medical conference.

“We are extremely pleased with these top-line results, which bring us one step closer to realizing the potential for a new treatment for mesothelioma patients in desperate need,” said Dr. Eilon Kirson, Novocure’s Chief Science Officer and Head of Research and Development. “Mesothelioma is the first torso indication for which Novocure will pursue FDA approval. The STELLAR data reinforce our belief that Tumor Treating Fields may be a broadly applicable platform technology for the treatment of solid tumors. We look forward to sharing the detailed results of the study with the lung cancer community at an upcoming medical conference.”

Novocure previously received Humanitarian Use Device (HUD) designation for the use of Tumor Treating Fields for the treatment of pleural mesothelioma. Based upon the final STELLAR data, Novocure plans to submit a Humanitarian Device Exemption (HDE) application to the FDA for approval. An approved HDE would allow Novocure to market Tumor Treating Fields in combination with standard of care chemotherapy as a treatment for pleural mesothelioma in the United States.

Tumor Treating Fields in combination with standard of care chemotherapy is an investigational treatment for pleural mesothelioma and is not approved for this indication. These results are preliminary top-line data and are subject to further analysis.

About STELLAR

The STELLAR trial is a phase 2 pilot single-arm, open-label, multi-center trial designed to test the efficacy and safety of Tumor Treating Fields in combination with standard of care chemotherapy, pemetrexed combined with cisplatin or carboplatin, in 80 patients with unresectable, previously untreated malignant pleural mesothelioma. The historical control for this trial is the results of the 2003 pemetrexed phase 3 FDA registration trial.

An interim analysis of the first 42 patients enrolled in the trial with an average follow-up time of 11.5 months was presented at the International Association for the Study of Lung Cancer in December 2016. The one-year survival rate of patients treated with Tumor Treating Fields combined with pemetrexed and cisplatin or carboplatin was 80 percent (compared to 50 percent in pemetrexed and cisplatin-alone historical controls). Median progression free survival in the Tumor Treating Fields-treated group was 7.3 months (compared to 5.7 months in pemetrexed and cisplatin-alone historical controls) and one-year survival rate was 79.7 percent (compared to 50.3 percent in pemetrexed and cisplatin-alone historical controls). Median overall survival had not yet been reached. No device-related serious adverse events had been reported to date.

About Mesothelioma

Malignant mesothelioma is a rare thoracic solid tumor cancer that has been strongly linked to asbestos exposure. It has a long latency period of at least 20-30 years following exposure, and global incidence is still increasing in countries where asbestos is still in use. There are approximately 3,000 new cases of mesothelioma annually in the United States. The prognosis of mesothelioma patients is very poor, with a median overall survival of approximately 12 months in most reported studies.
