Novocure’s Head Flexible Electrode (HFE) Transducer Arrays
Novocure has announced that its Head Flexible Electrode (HFE) transducer arrays have received approval from the U.S. Food and Drug Administration (FDA) for use with Optune Gio® in treating adult patients with glioblastoma multiforme (GBM), a type of brain cancer.
Optune Gio is a portable, wearable device designed to deliver Tumor Treating Fields (TTFields)—alternating electric fields aimed at disrupting the rapid division of cancer cells. These fields are delivered via wearable arrays, providing a non-invasive treatment option for patients. TTFields work by generating physical forces that target the electrically charged components of dividing cancer cells, ultimately interrupting their ability to proliferate.
The newly approved HFE arrays represent a significant advancement in the technology, replacing the ceramic discs used in the previous versions of the Optune Gio arrays. Made from a flexible polymer material, the new HFE arrays are not only lighter, weighing one-third less than their predecessors, but are also 50% thinner. This design innovation is expected to enhance patient comfort while continuing to provide effective treatment.
Mukund Paravasthu, Chief Operating Officer of Novocure, highlighted the company’s commitment to delivering innovations that make a meaningful difference for patients. He emphasized the comfort benefits of the new HFE arrays, which are lighter, thinner, and designed for better patient wearability. Novocure plans to implement a controlled transition plan to convert existing Optune Gio users in the U.S. to the new HFE arrays through the first half of 2025.

The FDA’s approval of Novocure’s Head Flexible Electrode (HFE) arrays marks a significant milestone in the ongoing evolution of non-invasive cancer treatments. Optune Gio has long been recognized as a promising therapeutic option for glioblastoma multiforme (GBM), and this latest iteration with the HFE arrays looks set to further improve the patient experience.
First, the technical enhancements to the Optune Gio device should not be underestimated. The shift from rigid ceramic discs to flexible polymer arrays is a move that directly addresses one of the key limitations of the original design: comfort. The previous version of the device, while effective in treating GBM, could be cumbersome and uncomfortable for patients, especially those required to wear the device for extended periods. By reducing the weight by a third and decreasing the thickness by half, the HFE arrays promise to make the treatment more comfortable, which is crucial when considering the psychological and physical burdens that patients with GBM already face.
However, while the reduction in size and weight will undoubtedly improve wearability, the core mechanism of the Optune Gio device remains unchanged: delivering Tumor Treating Fields (TTFields) to disrupt cancer cell division. This treatment has been proven to slow tumor growth, but its success is contingent on patient adherence. As Optune Gio becomes more comfortable with the new arrays, patient compliance with the long hours of treatment required could improve, further increasing the potential efficacy of the device.
From a broader market perspective, Novocure’s continual innovation is a strategic response to the competitive and fast-evolving field of cancer treatment. GBM remains one of the most aggressive forms of brain cancer, with limited treatment options available. In this context, any technological improvement that enhances a product’s usability without compromising its efficacy is a valuable development. Moreover, Novocure’s commitment to transitioning current Optune Gio users to the new HFE arrays by 2025 speaks to the company’s focus on long-term patient care and product integration. This transition plan will likely be a critical aspect of maintaining customer loyalty while expanding the product’s user base.
On the downside, the cost of Optune Gio and its associated treatment is a point that remains largely unaddressed in this announcement. Even with the new, lighter arrays, the financial burden of purchasing or renting the device, along with the costs of the consumables (such as the transducer arrays), could be a barrier for some patients. Insurance coverage and reimbursement policies will continue to play a major role in determining the accessibility of this treatment, particularly as Novocure seeks to transition all U.S. users to the new arrays.
Finally, while the HFE arrays provide a promising advancement in the product’s design, Novocure’s ongoing commitment to innovation and patient-centric improvements is what stands out the most in this update. The company’s focus on refining its technology to meet patient needs is a key differentiator that could further establish Optune Gio as a leader in the treatment of glioblastoma. However, future iterations of this technology will need to address both cost-effectiveness and broader accessibility to make a more significant impact in the global fight against GBM.
