Plain English Summary
Background and study aims
Pancreatic cancer is the third most common cancer related cause of death. Even in the 15% of patients who are eligible for surgical resection, less than 10% of patients surviving after 5 years. Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is an established treatment capable of curing a variety of hematopoietic malignancies, taking advantage of the graft-versus-tumor effect (GVT). It works best when the underlying neoplasm has been turned into a stage of minimal disease by chemotherapy. There have been attempts of applying allo-HSCT to advanced solid tumors including pancreatic cancer with limited success but studies of allo-HSCT in solid tumors in minimal disease situations have never been performed. The aim of this study is to provide evidence for the clinical value of allo-HSCT in pancreatic cancer put into a minimal disease status by effective surgical resection and standard adjuvant chemotherapy. We want to find out if allo-HSCT can change the unfavourable natural course of this disease and whether allo-HSCT is able to provide long-term disease control to an extent otherwise not possible in pancreatic cancer and improve survival of affected patients.
Who can participate?
Patients with histologically proven diagnosis of pancreatic ductal adenocarcinoma having undergone radical resection (R1/R0 local resection) within the last 4-6 months at the University Hospital Heidelberg, who are matching the inclusion criteria.
What does the study involve?
Patients will undergo conditioning for allo-HSCT (fludarabine 30mg/mE2/d d -6 through d -2, cyclophosphamide 60mg/kg/d d-3 and d -2) followed by transplantation of allogeneic unmanipulated peripheral blood stem cells on d 0. Standard GVHD prophylaxis with CSA (target level 150-200; start d -1, taper d +60 onwards in the absence of GVHD) and MMF (2x1g; start d 0, stop d +30 in the absence of acute GVHD) will be instituted.

Treatment
Patient information sheet
Condition
Pancreatic cancer resected in curative intention (Adjuvant setting)
Intervention
Eligible patients will be screened immediately after successful surgical resection, have a donor search initiated, and subjected to standard adjuvant chemotherapy.
Only those patients who underwent adjuvant chemotherapy without disease progression and who have a matched related stem cell donor available will be registered for the trial. Patients without a matched related donor will not be registered for the trial but may be used a historical control outside of the protocol.
Patients will undergo conditioning for allo-HSCT (fludarabine 30mg/mE2/d d -6 through d -2, cyclophosphamide 60mg/kg/d d-3 and d -2) followed by transplantation of allogeneic unmanipulated peripheral blood stem cells on d 0. Standard graft-versus-host disease (GVHD) prophylaxis with cyclosporine (CSA) (target level 150-200; start d -1, taper d +60 onwards in the absence of GVHD) and mycophenolate mofetil (MMF) (2x1g; start d 0, stop d +30 in the absence of acute GVHD) will be instituted.

Primary outcome measure
2-year progression-free survival (PFS) from registration.
Secondary outcome measures
1. 2-year PFS and overall survival (OS) after surgical resection
2. 2-year overall survival (OS) from registration
3. Minimal residual disease kinetics at screening day, registration day, 1, 3, 6, 12, 18 and 24 months according to study protocol (MRD; measured by tumor serum marker levels) and their correlation with immune events

2. Prevalence of chronic graft-versus-host-disease at 6, 12 and 24 months from allo-HSCT
3. Quality of life at day -28, day +28, day +100, day +180, day +360, day +720 before/after allo-HSCT
