Results from Phase 3 PANOVA-3 clinical trial presented at 2025 ASCO Annual Meeting and ESMO Gastrointestinal Cancers Congress 2025, selected as Best of ASCO 2025 and published in the Journal of Clinical Oncology

Novocure (NASDAQ: NVCR) today reported financial results for the second quarter that ended June 30, 2025. Novocure is a global oncology company working to extend survival in some of the most aggressive forms of cancer by developing and commercializing its innovative therapy, Tumor Treating Fields (TTFields).

“With the first half of 2025 complete, I am pleased to report continued progress towards our clinical, regulatory and commercial milestones. In Q2, we grew our glioblastoma and non-small cell lung cancer businesses and advanced our efforts to bring Tumor Treating Fields therapy to new patient populations,” said Ashley Cordova, CEO, Novocure. “With one launch ongoing and two more on the horizon, we are well-positioned in both the near and long term. This is a pivotal period for Novocure.”

Financial updates for the second quarter ended June 30, 2025:

• Total net revenues for the quarter were $158.8 million, an increase of 6% compared to the same period in 2024. This increase is primarily driven by active patient growth across our major markets.
  • The U.S., Germany, France and Japan contributed $94.3 million, $19.1 million, $18.4 million and $9.5 million, respectively, with other active markets contributing $13.0 million.
  • Revenue in Greater China from Novocure’s partnership with Zai Lab totaled $4.6 million.
  • Recognized revenue from Optune Lua^® in the quarter was $2.4 million, including $1.1 million from non-small cell lung cancer (NSCLC) and $1.3 million from malignant pleural mesothelioma (MPM).
• Gross margin for the quarter was 74% compared to 77% in the prior year. The reduction of gross margin was primarily driven by the roll out of our Head Flexible Electrode (HFE) transducer array for use with Optune Gio^®, the NSCLC launch where we are treating on-label patients at risk prior to establishing broad reimbursement, and increased tariffs.
• Research, development and clinical studies expenses for the quarter were $55.8 million, an increase of 2% from the same period in 2024. This was primarily driven by increased direct clinical trial expenses related to the ramp of the LUNAR-2 and KEYNOTE D58 trials.
• Sales and marketing expenses for the quarter were $57.1 million, an increase of 1% compared to the same period in 2024. This primarily reflects higher costs associated with the expansion of our NSCLC sales force.
• General and administrative expenses for the quarter were $44.0 million, an increase of 17% compared to the same period in 2024. This increase was primarily driven by higher share-based compensation expenses and higher personnel and professional service expenses to support the NSCLC launch and general company build-out, particularly on the enterprise technology side.
• Net loss for the quarter was $40.1 million with loss per share of $0.36.
• Adjusted EBITDA* for the quarter was $(9.9) million.
• Cash, cash equivalents and short-term investments were $911.5 million as of June 30, 2025.

Operational updates for the second quarter ended June 30, 2025:

• As of June 30, 2025, there were 4,331 total active patients on TTFields therapy globally.
• Optune Gio
  • 1,598 prescriptions for Optune Gio for the treatment of glioblastoma were received in the quarter, a decrease of 1% from the same period in 2024. The U.S., Germany, France and Japan contributed 963; 199; 179 and 101 prescriptions, respectively, with the remaining 156 prescriptions contributed by other active markets.
  • As of June 30, 2025, there were 4,194 Optune Gio active patients on therapy, an increase of 7% from the same period in 2024. The U.S., Germany, France and Japan contributed 2,177; 581; 453 and 451 Optune Gio active patients, respectively, with the remaining 532 active patients contributed by other active markets.
• Optune Lua
  • 143 total prescriptions for Optune Lua were received in the quarter. 121 Optune Lua prescriptions were received for the treatment of NSCLC and 22 prescriptions were received for the treatment of MPM.
  • As of June 30, 2025, there were 137 active Optune Lua patients on therapy, including 94 patients treated for metastatic NSCLC and 43 patients treated for MPM.

Quarterly updates and achievements:

• In May 2025, Novocure presented the results of the Phase 3 PANOVA-3 clinical trial at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting. PANOVA-3 met its primary endpoint, demonstrating a statistically significant extension in overall survival in patients treated with TTFields therapy together with gemcitabine and nab-paclitaxel compared to gemcitabine and nab-paclitaxel alone. Patients treated with TTFields therapy also exhibited a statistically significant extension in pain-free survival (secondary endpoint) and distant progression-free survival (post hoc analysis). The presentation was selected for inclusion in ‘Best of ASCO’ program and the data were simultaneously published in the Journal of Clinical Oncology.
• In July 2025, Novocure presented final quality of life data from the PANOVA-3 trial at the European Society for Medical Oncology (ESMO) Gastrointestinal Cancers Congress 2025. Patients treated with TTFields therapy demonstrated a statistically significant and clinically meaningful benefit across multiple quality of life measures of pain (secondary endpoint) and significantly delayed the need for opioid pain medication (post hoc analysis) for patients with unresectable, locally advanced pancreatic adenocarcinoma. A significant delay in deterioration across measures of health status was observed, preserving quality of life longer in patients treated with TTFields therapy.

Anticipated clinical and regulatory milestones:

• Novocure plans the submission of a Premarket Approval (PMA) application to the U.S. Food and Drug Administration (FDA) for the treatment of unresectable, locally advanced pancreatic cancer based on results of the Phase 3 PANOVA-3 clinical trial in Q3 2025.
• Novocure plans the submission of a PMA application to the FDA for the treatment of brain metastases from NSCLC based on results of the Phase 3 METIS clinical trial in H2 2025.
• The topline data readout from the Phase 2 PANOVA-4 clinical trial in metastatic pancreatic cancer is expected in H1 2026.
• The topline data readout from the Phase 3 TRIDENT clinical trial in newly diagnosed glioblastoma is expected in H1 2026.

*Non-GAAP Financial Measurements

We measure our performance based upon a non-U.S. GAAP measurement of earnings before interest, taxes, depreciation, amortization and shared-based compensation ("Adjusted EBITDA"). We believe Adjusted EBITDA is useful to investors in evaluating our operating performance because it helps investors compare the results of our operations from period to period by removing the impact of earnings attributable to our capital structure, tax rate and material non-cash items, specifically share-based compensation.
