Irreversible Electroporation (IRE) Followed by Nivolumab in Patients With Metastatic Pancreatic Cancer.
Irreversible Electroporation (IRE) Followed by Nivolumab in Patients With Metastatic Pancreatic Cancer: a Multicenter Single-arm Phase II Trial
Study Overview
Detailed Description
The prognosis of patients newly diagnosed with pancreatic ductal adenocarcinoma (PDAC) is extremely poor with a 5-year overall survival rate of less than 5%. To improve this dismal outcome, new treatment approaches are urgently needed. So far, immune-checkpoint therapy was not successful in patients with PDAC. Given the poor response to conventional chemotherapy, there is an imperative need to make PDACs amenable to immune-checkpoint therapy. Irreversible electroporation (IRE) is a relatively novel and safe ablation technique that destroys tumors by using apoptosis-inducing electrical currents inducing local and systemic pro-inflammatory cytokine expression and enhances the presence of cytotoxic CD8+ T-cells, while the apoptotic cell material preserves neo-antigen properties detectable by dendritic cells. This effect might be further enhanced by immune-checkpoint therapy.
The rationale of our study is to convert immunologically cold PDACs into hot PDACs by triggering an enhanced local and systemic immune response. We hypothesize that among patients with metastatic PDAC, the IRE of one liver metastasis followed by the administration of an immune-checkpoint inhibitor leads to a measurable radiological response in a selected non-treated liver metastasis. Furthermore, we hypothesize that the immune response is both local in the form of tumor infiltrating lymphocytes (TILS) and an immunologically activated tumor microenvironment in the IRE-treated metastasis, as well as systemic as evidenced by an abscopal response in the IRE-untreated metastatic and primary site.
The objective of the trial is to examine whether for patients with metastatic PDAC the combination of IRE of one liver metastasis followed by the administration of five doses of nivolumab leads to a measurable radiological response in a selected non-treated liver metastasis.
To demonstrate that the trial treatment leads to a measurable immune response, multiple translational research projects will assess the effect of IRE and nivolumab on the development of the local and peripheral tumor immune response over time.

The choice of chemotherapy regimen is based on the decision of the treating medical oncologist.
- Patients with a prior malignancy and treated with curative intention are eligible if all treatment of that malignancy was completed at least 2 years before registration and the patient has no evidence of that disease at registration. Note: Less than 2 years is acceptable for malignancies with low risk of recurrence and/or no late recurrence.

- Patients must be willing to travel to the hospital where IRE and biopsy will be performed (Claraspital Basel).
- Age ≥ 18 years
- WHO performance status 0-1

- Adequate coagulation function: INR ≤ 1.5 x ULN (the ULN for INR is defined with the value 1.2 for all sites, in case no ULN is documented in the lab certificates/sheets). In case patient is under anti-vitamin K treatment, INR >1.5 x ULN is allowed; however, the patient has to be switched to LMWH treatment prior to any trial intervention.

A negative pregnancy test before inclusion into the trial is required for all women of childbearing potential (for nivolumab product information).

- Any concomitant drugs contraindicated for use with the trial treatment according to the approved product information
- Known hypersensitivity to nivolumab or to any component of nivolumab, to stainless steel or to contrast agents.
- Any other serious underlying medical (in particular coagulation deficiencies), psychiatric, psychological, familial or geographical condition, which in the judgment of the investigator may interfere with the planned staging, treatment and follow-up, affect patient compliance or place the patient at high risk from treatment-related complications.

Experimental: Nivolumab
Nivolumab treatment will be given every 2 weeks at a standard flat dose of 240 mg for a total of 5 doses, and the IRE procedure will be performed using the standard setting to ablate tumors at the level of the liver that is well tolerated by the patients.
Two weeks after the last dose of nivolumab ("Week 8"), radiological restaging will be performed (="Week 10").
|
The patients start treatment with nivolumab on day 1 after IRE and will be given nivolumab at a flat dose of 240 mg every 2 weeks (q2wk) for 5 cycles until Week 8.
