Leukapheresis is performed of which the monocytes are used for differentiation
to dendritic cells using specific cytokines.
Pulsed autologous dendritic cells (MesoPher) are re-injected three times e

Eligibility
Age
18 Years to 99 Years
Inclusion criteria
Inclusion criteria: • Surgically resected pancreatic cancer. • Completed post-operative standard treatment. Patients who did not complete standard of care due to toxicity or who are not able to start standard of care due to specific reasons are allowed to participate in the study after approval of the coordinating investigator. • Patients who received standard of care post-operative treatment must be included within six months after completion of treatment. Patients who did not receive standard of care post-operative treatment must be included within six months after resection. • No disease activity as assessed by radiological imaging. • Patients must be at least 18 years old and must be able to give written informed consent. • Patients must be ambulatory (WHO-ECOG performance status 0,1 or 2) and in stable medical condition. • Patients must have normal organ function and adequate bone marrow reserve: absolute neutrophil count >1.0 x 10E9/l, platelet count > 100 x 10E9/l, and Hb > 6.0 mmol/l (as determined during screening). • Women of childbearing potential must have a negative serum pregnancy test at screening and a negative urine pregnancy test just prior to the first study drug administration on Day 1, and 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, 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. • Positive DTH skin test (induration > 2mm after 48 hrs) against at least one positive control antigen tetanus toxoid (see section 8.3 for DTH skin test procedure). • Ability to return to the hospital for adequate follow-up as required by this protocol. • Written informed consent according to ICH-GCP.
Exclusion criteria
Exclusion criteria: • Medical or psychological impediment to probable compliance with the protocol. • Current or previous treatment with immunotherapeutic agents. • Current use of steroids (or other immunosuppressive agents). Patients must have had 6 weeks of discontinuation and must stop any such treatment during the time of the study. Prophylactic usage of dexamethasone during chemotherapy is excluded from this 6 weeks interval. • Prior malignancy except adequately treated basal cell or squamous cell skin cancer, superficial or in-situ cancer of the bladder or other cancer for which the patient has been disease-free for five years. • Serious concomitant disease, or active infections. • History of autoimmune disease or organ allografts (or with active acute or chronic infection, including HIV and viral hepatitis). • Serious intercurrent chronic or acute illness such as pulmonary disease (asthma or COPD), cardiac disease (NYHA class III or IV), hepatic disease or other illness considered by the study coordinator to constitute an unwarranted high risk for investigational DC treatment. • Known allergy to shell fish (may contain keyhole limpet hemocyanin (KLH). • Pregnant or lactating women. • Inadequate vein access to perform leukapheresis. • Concomitant participation in another clinical trial (except participation in a biobank study). • An organic brain syndrome or other significant psychiatric abnormality which would compromise the ability to give informed consent, and preclude participation in the full protocol and follow-up. • Absence of assurance of compliance with the protocol. Lack of availability for follow-up assessment.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary endpoint of this project proposal is to determine the feasibility of administering MesoPher after standard of care adjuvant therapy in patients with resected pancreatic cancer. We deem this treatment feasible in case 8 out of 10 patients are able to complete the proposed treatment. | — |
Secondary
| Measure | Time frame |
|---|---|
| As a secondary endpoint we will assess the safety of MesoPher in surgically resected pancreatic cancer patients. In addition, we will determine the systemic immune profile, with emphasis on T lymphocytes, in surgically resected pancreatic cancer patients; and investigate how these immune profiles are affected by MesoPher treatment for individual patients. W will also look at efficacy of the treatment. | — |
