Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal disease with conventional treatments having little impact on disease course. Novel approaches are urgently needed to address inherent resistance to the current therapies and to identify new drugs or combinations that will have a high chance of success in pancreatic cancer patients. This proof-of-concept trial is studying the "dynamic" tumor response after the administration of a short course of gemcitabine and nab-paclitaxel (Abraxane) (a) during a window interval (4 weeks= 1 cycle) before surgery in resectable pancreatic cancer (cohort 1 = 21 patients) and (b) during at least 8 weeks (2 cycles) in locally advanced or metastatic pancreatic cancer (cohort 2 = 10 patients).

Eligibility |
Inclusion Criteria: - Histo(cyto)logically proven ductal pancreatic adenocarcinoma; - Resectable or potentially resectable tumor; resectability assessed during a multidisciplinary meeting with expert surgeon and radiologist (cohort 1), or locally advanced and/or metastatic tumor (cohort 2); - First line chemotherapy; - Age > 18 years; - WHO performance status (PS) grade 0 or 1; - Absolute neutrophil count > 1.5 x 10 9 / L, platelets > 100 x 10 9/ L, creatinine clearance (Cockcroft and Gault formula) > 60 ml/min, haemoglobin level > 10 g/dl (transfusions authorized), bilirubin<1.5 g/dl; - Optimal biliary drainage; - Women of child-bearing potential (WCBP), defined as a sexually mature woman who has not undergone a hysterectomy or tubal ligation of who has not been naturally postmenopausal for at least 24 consecutive months, must have a negative serum or urine pregnancy test prior to treatment. All WCBP, all sexually active male patients, and all partners of patients must agree to use adequate methods of birth control throughout the study; - Signed informed consent. Exclusion Criteria: - Previous anticancer therapy for the pancreatic adenocarcinoma; - Biliary obstruction without endoscopic biliary drainage; - Any contre-indication for surgery; - Prior malignancy (except non-melanoma skin cancer, and in situ carcinoma of the uterine cervix treated with a curative intent and any other tumor in complete remission with a disease-free interval > 3 years); - Uncontrolled congestive heart failure or angina pectoris, myocardial infarction within 1 year prior to study entry, uncontrolled hypertension (systolic pressure > 160 mm or diastolic pressure > 100 mm under well conducted antihypertensive treatment), QT prolongation; - Major uncontrolled infection; - Severe hepatic impairment; - Any medical, psychological, or social condition, which, in the opinion of the investigator, could hamper patient's compliance to the study protocol and/or assessment/interpretation of the data; - Pregnant or lactating women, or patients of both genders with procreative potential not using adequate contraceptive methods; - Patients receiving or having received any investigational treatment within 4 weeks prior to study entry, or participating to another clinical study; patients previously enrolled into this study. |

Other | Tumor response as assessed by Response Evaluation Criteria in Solid Tumors (RECIST) criteria | 4 weeks (duration of 1 cycle of neoadjuvant chemotherapy for resectable patients); 8 weeks (duration of 2 cycles of treatment for locally advanced and metastatic patients) | ||
Other | Effect of treatment on selected biomarkers in tumor resection specimens (cohort 1) and in case of obtaining tissue by Endoscopic Ultrasound-Guided Fine Needle Aspiration (EUS-FNA) (cohort 2) | Evaluation of biomarkers involved in gemcitabine and nab-paclitaxel activity : human equilibrative nucleoside transporter 1 (hENT1), deoxycytidine kinase (dCK), cytidine deaminase (CDA), secreted protein acidic and rich in cysteine (SPARC), taxanes-related biomarkers. | 4 weeks (duration of 1 cycle of neoadjuvant chemotherapy for resectable patients); 8 weeks (duration of 2 cycles of treatment for locally advanced and metastatic patients) | |
Primary | Dynamic tumor response rate as defined by a 40% modification of tumoral perfusion and cellular density parameters. | In order to detect changes in the tumor microenvironment and to monitor treatment efficacy, Dynamic Contrast Enhanced-Magnetic Resonance Imaging (DCE-MRI) and Diffusion Weighted-Magnetic Resonance Imaging (DW-MRI) constitute tools more and more used. The acquired data can be analyzed using a pharmacokinetic model to obtain quantitative parameters relative to tissue perfusion and vascular permeability (Ktrans, a volume transfer constant of contrast agent between blood plasma and the extravascular extracellular space; Apparent Coefficient Diffusion as a surrogate marker of tissue cellularity). DCE/DW-MRI will be achieved before each chemotherapy treatment (and also before surgery for resectable patients). Each patient will be his/her own control by comparing serial imaging results with those of the baseline MRI. | 4 weeks (duration of 1 cycle of neoadjuvant chemotherapy for resectable patients); 8 weeks (duration of 2 cycles of treatment for locally advanced and metastatic patients) | |
Secondary | Number of participants with adverse events as assessed by National Cancer Institute (NCI) Common Toxicity Criteria for Adverse Effects (CTCAE) V4.0. | Number of participants with (serious) adverse events will be considered as a measure of safety of the whole therapeutic sequence (gemcitabine+Abraxane+surgery for resectable patients; gemcitabine+Abraxane for locally advanced/metastatic patients) | 12 months |
