p. administration and restimulation with trAb in patients with PC. Patients and methods Objectives and study approval This study was designed as a sequential dose-escalating, feasibility study for compassionate use of trAb in the induction of tumor immunity. The study was carried out according to the principles of the Declaration of Helsinki and good clinical practice guidelines. It was approved by the Ethics committee of the see more Ludwig-Maximilians-University, Munich, Germany. Informed consent was obtained from all patients prior to treatment. Patients Patients enrolled in this study had histologically confirmed diagnosis of PC. Inclusion

criteria were Karnofsky performance status ≥ 60%, white blood cell count > 2000/mm3 and a relative T-cell count > 10%. Exclusion criteria included prior immunotherapy, significant heart disease or arrhythmia,

known allergic reactions or Neuronal Signaling autoimmune disease, significant liver, kidney, pulmonary or haematological disease, acute or chronical infection and paracentesis of malignant ascites > 1000 ml within 30 days before treatment. Patients were included independent of any prior conventional therapy, i.e. chemotherapy, radiation or tumor surgery. An interval of more than 30 days between any chemotherapy and the start of the trAb therapy was required. A recovery interval of at least 7 days after abdominal surgery with {Selleck Anti-infection Compound Library|Selleck Antiinfection Compound Library|Selleck Anti-infection Compound Library|Selleck Antiinfection Compound Library|Selleckchem Anti-infection Compound Library|Selleckchem Antiinfection Compound Library|Selleckchem Anti-infection Compound Library|Selleckchem Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|buy Anti-infection Compound Library|Anti-infection Compound Library ic50|Anti-infection Compound Library price|Anti-infection Compound Library cost|Anti-infection Compound Library solubility dmso|Anti-infection Compound Library purchase|Anti-infection Compound Library manufacturer|Anti-infection Compound Library research buy|Anti-infection Compound Library order|Anti-infection Compound Library mouse|Anti-infection Compound Library chemical structure|Anti-infection Compound Library mw|Anti-infection Compound Library molecular weight|Anti-infection Compound Library datasheet|Anti-infection Compound Library supplier|Anti-infection Compound Library in vitro|Anti-infection Compound Library cell line|Anti-infection Compound Library concentration|Anti-infection Compound Library nmr|Anti-infection Compound Library in vivo|Anti-infection Compound Library clinical trial|Anti-infection Compound Library cell assay|Anti-infection Compound Library screening|Anti-infection Compound Library high throughput|buy Antiinfection Compound Library|Antiinfection Compound Library ic50|Antiinfection Compound Library price|Antiinfection Compound Library cost|Antiinfection Compound Library solubility dmso|Antiinfection Compound Library purchase|Antiinfection Compound Library manufacturer|Antiinfection Compound Library research buy|Antiinfection Compound Library order|Antiinfection Compound Library chemical structure|Antiinfection Compound Library datasheet|Antiinfection Compound Library supplier|Antiinfection Compound Library in vitro|Antiinfection Compound Library cell line|Antiinfection Compound Library concentration|Antiinfection Compound Library clinical trial|Antiinfection Compound Library cell assay|Antiinfection Compound Library screening|Antiinfection Compound Library high throughput|Anti-infection Compound high throughput screening| laparotomy was mandatory. All patients had a surgical procedure (explorative laparotomy or laparoscopy, resection of intra-abdominal metastases), where isolation of autologous tumor samples was possible. Isolation and storage of autologous tumor cells Autologous tumor samples were taken during surgery (explorative laparotomy or laparoscopy, resection of intra-abdominal metastasis). The surgical procedure was independent from study inclusion. Patients were only included if more than 5 × 106 autologous tumor cells were successfully

isolated, and if EpCAM antigen or HER2/neu antigen was found on > 10% of all viable cells ifoxetine from autologous tumor cell preparations. Analysis of autologous tumor cells was performed by immunohistochemical APAAP staining [23] using the antibodies HO3 (anti-EpCAM; mouse IgG2a, TRION Pharma) or C215 (anti EpCAM; mouse IgG2a; kindly provided by M. Dohlsten, Pharmacia, Uppsala, Sweden) for EpCAM or 2502A (anti Her2/neu; mouse IgG2a; Trion Pharma, Munich, Germany) for HER2/neu. After surgical resection autologous tumor probes were dissected into 2–3 mm3 pieces which were then immersed in RPMI 1640 medium (containing 0.05% Collagenase type 4, 0.02% DNAse type 1, Penstrep, Gentamycin and Amphotericin B; all reagents from Invitrogen, Carlsbad, California). This mixture was incubated overnight at 37°C and filtered through a flexible grid to exclude undigested tissue fragments.
