The TRIDENT trial (also known as the “EF-32 trial”) is a randomized, controlled study, testing the safety and efficacy of Tumor Treating Fields (TTFields) from the Optune® System together with radiation therapy and temozolomide in newly diagnosed glioblastoma (GBM) patients.

Patients in the study will use Optune® as well as the other standard of care treatments for GBM. The trial is expected to enroll 950 patients. Enrollment is open in multiple centers in the US, Canada, Japan, and across Europe.

Tumor Treating Fields (TTFields) are low-intensity wave-like electric fields, tuned to interfere with the division process of cancer cells.

TTFields are delivered to the region of the tumor using the Optune® medical device. The Optune® System is a portable, light-weight, battery operated device designed to deliver TTFields to glioblastoma (GBM) tumors.

Patients receiving TTFields need to wear four adhesive patches called “transducer arrays” on their scalp, which deliver the fields non-invasively to the location of the GBM tumor. The system is intended for continuous use by patients.

TTFields have been approved by the FDA for treatment of adult patients with recurrent and newly diagnosed GBM. What makes the TRIDENT study different is that is testing the use of Optune® together with radiation therapy (RT) and temozolomide (TMZ) in newly diagnosed patients.

The TRIDENT study is for patients recently diagnosed with glioblastoma (GBM). This clinical trial is evaluating the safety and efficacy of Tumor Treating Fields (TTFields) delivered by the Optune® treatment paired with radiation therapy and temozolomide in newly diagnosed GBM patients [About TTFields].  All patients participating in this study will receive Optune® treatment [The TRIDENT Trial].
