What this study is testing
Phase II: An improvement in the progression-free survival (PFS) per RECIST 1.1 of adjuvant dendritic cell therapy (MesoPher) in patients with ABC borderline resectable pancreatic cancer (exploratory) Phase III: To investigate the overall survival (OS) of MesoPher treatment.

Who can take part
You may be able to join if
- At registration: ABC borderline resectable pancreatic cancer, histologically or cytologically confirmed. ABC borderline is defined as resectable pancreatic cancer with a CA-19.9 level > 500 kU/L at diagnosis or borderline resectable pancreatic cancer. Resectability criteria are defined by the DPCG criteria.
- Laboratory tests: ASAT/ALAT <5xULN (upper limit of normal), bilirubin <1.5xULN, Lactate dehydrogenase value < ULN and albumin value > 30.
- Women of childbearing potential (WOCB) must have a negative serum pregnancy test at screening. They must be willing to use an effective contraceptive method (intrauterine devices, hormonal contraceptives, contraceptive pill, implants, transdermal patches, hormonal vaginal devices, infusions with prolonged release) or true abstinence (when this is in line with the preferred and usual lifestyle*) during the study and for at least 12 months after the last study drug administration. *True abstinence is acceptable when this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (such as calendar, ovulation, symptothermal, and post-ovulation methods) and withdrawal are not acceptable methods of contraception.
- Men must be willing to use an effective contraceptive method (e.g. condom, vasectomy) during the study and for at least 12 months after the last study drug administration.
- Ability to return to the hospital for adequate follow-up as required by this protocol.
- Written informed consent according to ICH-GCP.
You likely can't join if
- At registration: a. Metastatic or locally advanced (unresectable) pancreatic cancer according to the DPCG criteria. b. Resectable pancreatic cancer with a CA19-9 < 500 kU/L at registration, unless predefined exception criteria (e.g. CA19-9 non-producer with PET-CT showing no distant metastases and no metabolic progression) are met and eligibility is confirmed by the central study team.
- Has a known additional malignancy that is progressing or has required active treatment within the past two years. Participants with basal cell carcinoma of the skin, squamous cell carcinoma of the skin or carcinoma in situ (e.g., breast cancer, cervical cancer in situ) that have undergone potentially curative therapy are not excluded.
- Has active autoimmune disease that has required systemic treatment in the past two years (i.e. with the use of disease-modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered systemic treatment and is allowed.
- Has a history of (non-infectious) pneumonitis that required steroids or has current pneumonitis.
- Has an active infection requiring systemic therapy.
- Has a known history of Human Immunodeficiency Virus (HIV) infection.

- Written informed consent according to ICH-GCP.
- Inclusion and randomisation: Borderline resectable or resectable tumours according to the DPCG criteria. CA-19.9 levels of no more than 500 kU/L at the time of screening, and a valid reduction during neoadjuvant FOLFIRINOX according to the treating physician. Predefined exceptions apply for CA19-9 non-producers with PET-CT showing no metabolic progression, and for patients with CA19-9 levels above 500 kU/L who have demonstrated a valid reduction during FOLFIRINOX and are deemed clinically eligible by the treating physician, subject to approval after consultation with the central study team.
- Patients must be at least 18 years old and be able to give written informed consent.
- WHO performance status 0-1.
- Patients must be able to undergo surgery.
- Patients must have normal organ function and adequate bone marrow reserve: absolute neutrophil count > 1.0 x 109/l, total leucocyte count ≥ 3.0 x 109/l, platelet count > 100 x 109/l, renal function E-GFR ≥ 50 ml/min, and Hb > 6.0 mmol/l.
What rules you out
