简要总结
Irreversible electroporation is a local ablative technique used in the treatment of pancreatic cancer. In addition to its cytoreductive ability, IRE also induces a systemic immune response. However, this immune response is not potent enough to establish durable regression of the tumor. The immune response can be leveraged by combining IRE with immunotherapy. The primary aim of this study is to determine the safety of IRE + Nivolumab (arm B) and IRE + Nivolumab + CpG (arm C). The secondary aim is to assess efficacy of the experimental arms (B, C) and control arm A (Nivolumab monotherapy), based on overall and progression-free survival as well as locoregional and systemic immune modulation.
详细描述
Pancreatic carcinoma is one of the deadliest types of cancer. In contrast to other cancers, new treatment options have demonstrated only moderate improvements for pancreatic cancer in terms of overall survival. Patients with metastasized disease (stage IV, AJCC) that are treated with chemotherapy in the Netherlands currently present a median overall survival of 6.4 months. Previous research has shown promising results for patients with locally advanced pancreatic cancer (LAPC, stage III, AJCC) with regards to combination treatment with chemotherapy and irreversible electroporation (IRE), a local ablation technique that utilizes electrical pulses to destroy cancerous tissue. In addition to an increase in overall survival, IRE induced a systemic immune response. However, the immune response was not potent enough to generate a lasting anti-tumor effect. Leveraging the body's own immune response by using local and systemic immunotherapy may create a synergistic effect, potentially inducing a durable anti-tumor response. The PANFIRE-III is a prospective randomised phase 1 trial with the primary aim to determine safety of the combination therapies IRE + Nivolumab (arm B) and CpG + IRE + Nivolumab (arm C) in patients with oligo-metastasized pancreatic cancer. The secondary goal is to determine efficacy of the experimental arms (arm B, C) compared to the control arm A (Nivolumab monotherapy). This will be assessed by looking at the overall and progression-free survival as well as the locoregional and systemic immune response. The treatment combination of IRE with immunotherapy has the potential to generate systemic protection by in vivo vaccination against pancreatic cancer cells, hereby inhibiting both local and distant tumor growth.

研究组 & 干预措施
Arm A: Nivolumab
4 weeks after pre-treatment with FOLFIRINOX (4-8 cycles), the patient will start with the Nivolumab scheme. The first month, a biweekly dose of 240 mg will be administered, followed by a monthly dose of 480 mg. This treatment will continue until disease progression.
干预措施: Nivolumab (Drug)
Arm B: IRE + Nivolumab
4 weeks after pre-treatment with FOLFIRINOX (4-8 cycles), the patient will first receive (an incomplete) IRE of the primary pancreatic tumor. 2 weeks thereafter, they will start the Nivolumab scheme. The first month, a biweekly dose of 240 mg will be administered, followed by a monthly dose of 480 mg. This treatment will continue until disease progression.
