Japan approves Novocure’s Optune Lua for advanced lung cancer treatment

BAAR, Switzerland - Japan’s Ministry of Health, Labour and Welfare has approved Novocure’s (NASDAQ:NVCR) Optune Lua device for concurrent use with PD-1/PD-L1 inhibitors in adult patients with unresectable advanced or recurrent non-small cell lung cancer (NSCLC) who have progressed on or after platinum-based chemotherapy. The medical device company, currently valued at $1.36 billion, maintains a strong balance sheet with more cash than debt, according to InvestingPro data.

The approval is based on results from the Phase 3 LUNAR trial, which demonstrated a statistically significant 3.3-month improvement in median overall survival for patients treated with Optune Lua in combination with either PD-1/PD-L1 inhibitors or docetaxel compared to those treatments alone.

Patients receiving Optune Lua with a PD-1/PD-L1 inhibitor showed a median overall survival of 19.0 months versus 10.8 months for patients on a PD-1/PD-L1 inhibitor alone, representing an 8.0-month survival extension.

Optune Lua is a wearable medical device that delivers Tumor Treating Fields (TTFields), which are alternating electric fields that disrupt cancer cell division through non-invasive arrays worn by patients.

"With the Ministry of Health, Labour and Welfare approval granted to Optune Lua, we now have a new treatment option available to patients with advanced non-small cell lung cancer," said Dr. Tetsuya Mitsudomi, President of Izumi City General Hospital.

Device-related adverse events occurred in 63.1% of patients, primarily consisting of low-grade skin reactions where the transducer arrays were placed. Only 4% of patients experienced Grade 3 skin toxicity requiring treatment interruption, with no Grade 4 or 5 toxicities reported.

Lung cancer is the leading cause of cancer-related death worldwide, with approximately 120,000 patients diagnosed with NSCLC annually in Japan, according to the company’s press release statement. Despite reporting impressive revenue growth of 14.58% and maintaining a robust gross profit margin of 76.54%, Novocure’s stock has faced headwinds, declining 59% year-to-date. InvestingPro analysis suggests the stock is currently undervalued, with analysts setting price targets ranging from $14.50 to $38.00 per share.

Novocure stated it is focused on launching Optune Lua in Japan as quickly as possible to provide access to patients who have progressed after initial platinum-based treatment. The company’s next earnings report is scheduled for October 23, where investors will gain further insights into the commercial rollout strategy and financial outlook.
