The FDA recently approved a revolutionary device by Novocure, named Optune Lua, designed to treat non-small cell lung cancer through the creation of electric fields. These fields, according to the manufacturer, interfere with the division of malignant cells, offering a new avenue of treatment when combined with standard therapies such as immunotherapy or chemotherapy. This clearance by the FDA came after observing positive results from the “Lunar” Phase 3 trial, wherein patients using this device alongside standard treatments showed a 26% reduced risk of death over approximately 10 months.
The Lunar trial involved 276 patients who had experienced cancer progression after initial platinum-based chemotherapy. These patients were randomly assigned either the combination of the TTF device and standard therapies (chemo or PD-1 inhibitors like Merck & Co.’s Keytruda) or just the standard therapies alone. The results were statistically significant—those using the TTF device showed a median survival of 13.2 months compared to 9.9 months for those receiving only drug therapy.
Despite these encouraging results, some skepticism exists within the medical and investment communities, particularly surrounding the trial’s methodology. Experts point out potential issues such as the inclusion of immunotherapies in the trial, which are generally used as a first-line treatment rather than alongside chemotherapy in second-line treatments, as was done in the study. Jonathan Chang from Leerink Partners criticized this approach, arguing that Optune Lua should have only been tested with chemotherapy to better reflect real-world practices. Furthermore, he highlighted that the survival improvement specifically between the chemo-only group and those using Optune Lua with chemo wasn’t statistically significant, with just a 2.4-month difference.
Adding to the complexity, the actual influence of PD-1 status on the trial’s results was unclear, with many participants having an unknown PD-1 status. This factor could have potentially skewed the effectiveness data. Future trials, including Lunar-2 and Lunar-4, are set to provide further clarity by evaluating Optune Lua in different treatment combinations and setups, with results expected in 2026 and 2028.
The approval of Optune Lua opens new potential revenue streams for Novocure. Despite a lag in the company’s revenue against its expenditures—recording a shortfall of $207 million in 2023 and $72 million in the first half of 2024—the approval has already positively impacted its market value. Following the announcement, Novocure’s shares initially jumped by 22%, although they later moderated to a 5% increase. This reflects a growing investor confidence in the device’s market potential, likely spurred by the significant market size for lung cancer treatments.
Overall, while the lung cancer approval of Optune Lua introduces a promising technology into the treatment paradigm, its optimal placement within current clinical practices remains under discussion. The forthcoming trial results will be critical in defining how this device can best be integrated with existing therapies to provide the most benefit to patients, potentially paving the way for broader adoption and significant revenue growth for Novocure.
