The PANOVA trial (also known as the “EF-20 trial”) is a Pilot (analogous to drug Phase II), single arm trial. It is designed to test the safety and preliminary efficacy of a medical device, the NovoTTF-100L(P) system  in patients with pancreatic cancer which is not amenable to surgical resection, when the device is combined with standard chemotherapy for pancreatic cancer. The device administers TTFields to patients concomitantly to the best standard of care treatments which would normally be used to treat their pancreatic cancer – gemcitabine or nab-paclitaxel (brand name: abraxane). The trial is expected to enroll a total of 40 patients. The first 20 patients have been enrolled in the trial and received gemcitabine alongside with TTFields. The next 20 patients are going to be treated with nab-paclitaxel (abraxane) combined with TTFields. The trial is now enrolling patients in multiple centers in Europe.

The PANOVA Trial Design

Patients with newly diagnosed, unresectable and previously untreated pancreatic adenocarcinoma are candidates for the clinical trial. Final eligibility can only be determined by the clinical trial physician at one of the clinical trial sites. All patients enrolled in the trial will receive the best standard treatments (including chemotherapy) for their pancreatic cancer and for any other medical condition, similar to patients who are not participating in the trial, together with TTFields. TTFields will be administered continuously to all patients enrolled in the trial, until disease progression. Eligible patients will start both chemotherapy and TTFields at the same time, and should therefore consult with their treating doctor about their potential participation in the trial soon after being diagnosed with pancreatic cancer.

In order to apply the NovoTTF-100L(P) device, the patient needs to wear four transducer arrays taped around the abdominal region. Routine transducer array placement (every 3-4 days) will require shaving of hair-containing skin surfaces with a simple shaver provided at treatment start, if relevant. Since the transducer arrays are placed on skin covered by clothes, they may not be visible to others.

The use of the device will start in an outpatient setting and will include training on the operation of the equipment by a qualified Novocure Device Support Specialist (DSS). Patients will continue to use the device at home. Patients using the NovoTTF-100L(P) System can maintain the use of the device alone (with the help of a family member or a care giver if needed) or receive support from their DSS.

The system is user-friendly and all technical aspects related to using it are maintained by the DSS. The DSS can also help patients in finding technical solutions to allow each individual to receive TTFields while maintaining his/her normal daily routines.


For the complete list of eligibility criteria please go to clinical or consult with a PANOVA trial physician:

Trial Costs

The trial sponsor (Novocure) will pay for reasonable treatment related solutions, including the NovoTTF-100L(P) system and accessories. The trial sponsor will also reimburse patients for travel costs related to trials procedure. Such reimbursement can only be done according to the policy of the trial center the patient is treated at and upon approval by the trial sponsor. Please consult with the clinical trial team at the center prior to enrolling in the trial about the local reimbursement policy and your rights. Patients and their insurance will be responsible for medical treatments received in the normal course of patient care.
