Zai Lab and Novocure Announce Pivotal LUNAR Study in Non-Small Cell Lung Cancer Met Primary Overall Survival Endpoint

The LUNAR study met its primary endpoint, demonstrating a statistically significant and clinically meaningful improvement in overall survival

The full LUNAR data will be presented at a future medical congress

SHANGHAI and CAMBRIDGE, Mass. and ROOT, Switzerland, Jan. 05, 2023 (GLOBE NEWSWIRE) -- Zai Lab Limited (Nasdaq: ZLAB; HKEX: 9688) and Novocure (NASDAQ: NVCR) today announced the LUNAR study met its primary endpoint, demonstrating a statistically significant and clinically meaningful improvement in overall survival over standard therapies alone. The LUNAR study is a pivotal, open-label, randomized study evaluating the safety and efficacy of Tumor Treating Fields (TTFields) together with standard therapies for stage 4 non-small cell lung cancer (NSCLC) following progression while on or after treatment with platinum-based therapy.

The LUNAR study also showed a statistically significant and clinically meaningful improvement in overall survival when patients were treated with TTFields and immune checkpoint inhibitors (ICI), as compared to those treated with immune checkpoint inhibitors alone, and a positive trend in overall survival when patients were treated with TTFields and docetaxel versus docetaxel alone. Patient enrollment was well balanced between the ICI and docetaxel cohorts of the experimental and control arms, and control arms performed in line with prior studies. TTFields therapy was well tolerated by patients enrolled in the experimental arm of the study.

“We are pleased with the positive readout of the LUNAR study. Prior to LUNAR, the last phase 3 trial to lead to significant improvement in overall survival in late-stage, platinum-resistant non-small cell lung cancer was six years ago, underlining the difficulty in treating this disease,” said William Doyle, Novocure’s Executive Chairman. “We are also pleased by the profound performance of the TTFields together with immunotherapy, which has the potential to meaningfully extend patient survival beyond what was previously possible. I would like to thank our patients and investigators for their courage and dedication in completing LUNAR. And, I would like to thank Novocure’s employees for their unrelenting commitment to patients and their perseverance in propelling Novocure to this major milestone.”

“We are excited about the potential of TTFields to address the unmet medical needs of lung cancer patients around the world. In China, lung cancer is the most common cancer type with approximately 700,000 new NSCLC cases diagnosed each year,” said Dr. Samantha Du, Founder, Chairperson, and CEO of Zai Lab. “We are pleased to contribute and be a part of the LUNAR study and this partnership is yet another great example of how collaboration benefits everyone.”

Novocure plans to release the full results of the LUNAR study at a future medical conference. Novocure expects to file a Premarket Approval application with the U.S. Food and Drug Administration (FDA) in the second half of 2023. Novocure also expects to file for a CE Mark in the European Union concurrently with the FDA submission.

About LUNAR
LUNAR is a pivotal study testing the safety and effectiveness of TTFields when used together with immune checkpoint inhibitors or docetaxel (experimental arm) versus immune checkpoint inhibitors or docetaxel alone (control arm) 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. The powered secondary endpoints are superior overall survival of patients treated with TTFields plus immune checkpoint inhibitor versus immune checkpoint inhibitor alone (ICI cohort) and superior overall survival of patients treated with TTFields plus docetaxel versus docetaxel alone (docetaxel cohort). TTFields is intended principally for use with other concomitant 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 Non-Small Cell Lung Cancer in China
Lung cancer is the most commonly diagnosed cancer type and the leading cause of cancer death in China. There were approximately 815,563 new cases and 714,699 deaths of lung cancer in China in 2020, respectively. NSCLC accounts for approximately 85% of lung cancer, and approximately 70% of NSCLC is locally advanced or metastatic at initial diagnosis. Similar to the global clinical practice, physicians use different combinations of surgery, radiation and pharmacological therapies to treat NSCLC, depending on the stage of the disease. Surgery, which may be curative in a subset of patients, is usually used in early stages of the disease. Since 1991, radiation with a combination of platinum-based chemotherapy drugs has been the first-line standard of care for locally advanced or metastatic NSCLC. Certain immune checkpoint inhibitors have been approved for the first-line treatment of NSCLC and the standard of care in this setting appears to be evolving rapidly. The standard of care for second-line treatment is also evolving and may include platinum-based chemotherapy for patients who received immune checkpoint inhibitors as their first-line regimen, pemetrexed, docetaxel or immune checkpoint inhibitors.

About Tumor Treating Fields Therapy
Tumor Treating Fields (TTFields) are electric fields that exert physical forces to kill cancer cells via a variety of mechanisms. TTFields do not significantly affect healthy cells because they have different properties (including division rate, morphology, and electrical properties) than cancer cells. The multiple, distinct mechanisms of TTFields therapy work together to selectively target and kill cancer cells. Due to its multimechanistic actions, TTFields therapy can be added to cancer treatment modalities in approved indications and demonstrates enhanced effects across solid tumor types when used with chemotherapy, radiotherapy, immune checkpoint inhibition, or PARP inhibition in preclinical models. TTFields therapy provides clinical versatility that has the potential to help address treatment challenges across a range of solid tumors.
