About this study
Official title: PANOVA-4: Pilot, Single Arm Study of Tumor Treating Fields (TTFields, 150kHz) Concomitant With Atezolizumab, Gemcitabine and Nab-Paclitaxel as First-Line Treatment for Metastatic Pancreatic Ductal Adenocarcinoma (mPDAC)
The PANOVA-4 study is designed to evaluate the safety and efficacy of Tumor Treating Fields (TTFields) therapy together with atezolizumab, gemcitabine and nab-paclitaxel, for the treatment of metastatic pancreatic cancer. The study is intended for patients who have been diagnosed with metastatic pancreatic cancer and have not received prior systemic therapy.
Read the detailed description
The PANOVA-4 study is an international, multi-center, research study for female and male adult patients diagnosed with metastatic pancreatic ductal adenocarcinoma (mPDAC).
The purpose of the study is to test the efficacy and safety of TTFields, delivered using the NovoTTF-200T Treatment Kit, concomitantly with atezolizumab, gemcitabine and nab-paclitaxel as first line treatment for Metastatic Pancreatic Ductal Adenocarcinoma (mPDAC).
The chemotherapy used in this study, gemcitabine and nab-paclitaxel, are standard-of-care treatment for metastatic pancreatic cancer. The atezolizumab drug and the NovoTTF-200T device are investigational for this tumor type. Atezolizumab is an immunotherapy drug that works with the immune system to help fight cancer. NovoTTF-200T is a non-invasive medical device that delivers Tumor Treating Fields (TTFields) at 150kHz to the cancer in the abdominal region, where the tumor is located.
The study is expected to enroll 76 patients in centers around the world. The expected duration on study per patient is approximately 12 months.
Patients with previously untreated mPDAC who meet all inclusion criteria and none of the exclusion criteria as determined by the investigator will initiate study treatment within 28 days from signing the Informed Consent Form (ICF) to receive TTFields (150 kHz), atezolizumab, gemcitabine and nab-paclitaxel.
All patients enrolled in the study will receive continuous TTFields therapy concomitant with monthly atezolizumab treatments for their metastatic pancreatic cancer and weekly gemcitabine and nab-paclitaxel.
While on the study, patients will be asked to visit the clinic every 4 weeks, in order to perform a physical examination, blood tests,and some other assessments. Patients will be asked to have a radiological examination (CT scan of the chest abdomen and pelvis) every 8 weeks to assess the status of the disease.
Study treatments will continue until disease progression according to RECIST v1.1, or loss of clinical benefit.
Patients who experience disease progression will be permitted to continue study treatments if there is evidence of clinical benefit.
Subjects will return to the clinic for one final visit approximately 30 days after discontinuation of the last study treatment.
Following the final visit, the subjects will be contacted every three months by telephone to answer basic questions about their health status.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Tumor Treating FieldsDevice
Also called NovoTTF-200T
The NovoTTF-200T is a portable, battery operated system intended for continuous home use, which delivers TTFields at a frequency of 150kHz to the patient by means of insulated transducer arrays. The NovoTTF-200T produces TTFields that exert electric forces intended to disrupt cancer cell division.
TTFields at 150 kHz application will be continuous for at least 18 hours a day on average. TTFields will be continued until disease progression according to RECISTv1.1 or loss of clinical benefit.
AtezolizumabDrug
Also called Tecentriq (Brand name)
Atezolizumab is a humanized IgG1 monoclonal antibody which targets human PD-L1and inhibits its interaction with its receptors, PD-1 and B7.1 (CD80). Both of these interactions are reported to provide inhibitory signals to T cells. Atezolizumab is administered as an intravenous solution.
Atezolizumab may continue until disease progression according to RECIST v1.1 or loss of clinical benefit.
GemcitabineDrug
Also called Gemzar
Gemcitabine is a standard of care chemotherapy drug administered as an intravenous infusion.
Gemcitabine may continue until disease progression according to RECIST v1.1 or loss of clinical benefit.
nab-paclitaxelDrug
Also called Abraxane
Nab-paclitaxel is a standard of care chemotherapy drug administered as an intravenous infusion.
Nab-paclitaxel may continue until disease progression according to RECIST v1.1 or loss of clinical benefit.

| AtezolizumabAlso: Tecentriq (Brand name)Atezolizumab is a humanized IgG1 monoclonal antibody which targets human PD-L1and inhibits its interaction with its receptors, PD-1 and B7.1 (CD80). Both of these interactions are reported to provide inhibitory signals to T cells. Atezolizumab is administered as an intravenous solution. Atezolizumab may continue until disease progression according to RECIST v1.1 or loss of clinical benefit. | Drug | TTFields + atezolizumab + gemcitabine and nab-paclitaxel |
| GemcitabineAlso: GemzarGemcitabine is a standard of care chemotherapy drug administered as an intravenous infusion. Gemcitabine may continue until disease progression according to RECIST v1.1 or loss of clinical benefit. | Drug | TTFields + atezolizumab + gemcitabine and nab-paclitaxel |
| nab-paclitaxelAlso: AbraxaneNab-paclitaxel is a standard of care chemotherapy drug administered as an intravenous infusion. Nab-paclitaxel may continue until disease progression according to RECIST v1.1 or loss of clinical benefit. | Drug | TTFields + atezolizumab + gemcitabine and nab-paclitaxel |
Primary outcome
Disease control rate (DCR)
Time frame: at least 16 weeks for SD or confirmed PR/CR
Disease control rate (DCR) will be measured by the proportion of patients who had either stable disease (SD) for at least 16 weeks or confirmed partial response (PR) or complete response (CR) according to RECIST v1.1
7 secondary outcomes
Overall survival (OS)
Time frame: up to 4 years
Progression-free survival (PFS)
Time frame: up to 4 years
1-Year survival rate
Time frame: alive at 1 year following treatment initiation
Objective response rate (ORR)
Time frame: up to 4 years
Progression free survival at 6 months (PFS6)
Time frame: 6 months following treatment initiation
Duration of response (DOR)
Time frame: up to 4 years
Rate of of patients with treatment emergent adverse events
Time frame: up to 4 years

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 42 inclusion and 49 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 4 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 15 sites in Spain, Czechia, Germany, Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Disease control rate (DCR) (time frame: at least 16 weeks for SD or confirmed PR/CR). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Sep 2026.
