The investigators propose to study the efficacy and safety of nab-Paclitaxel in a Phase II trial of patients with locally advanced or metastatic adenocarcinomas of the stomach and gastro-esophageal junction

Adenocarcinomas of the stomach or gastrointestinal junction refractory/resistant to 1st line chemotherapy are considered as an orphan disease with limited (if any) treatment options. The promising results of Nab-Paclitaxel derived from preclinical studies and from clinical trials conducted in breast cancer patients open the field to develop such therapeutic approaches in other cancers types usually treated with taxanes such as gastric and GEJ adenocarcinomas. We design a phase II study in order to evaluate the effect of nab-Paclitaxel as salvage treatment for patients with advanced cancer of the stomach and GEJ previously treated with the DCF regimen.

Inclusion Criteria:

• Age >18 years old
• Disease progression after treatment with the DCF regimen

• Aspartate Aminotransferase and Alanine Aminotransferase less than 2.5 times the upper normal limit
• Creatinine Clearance ≥50 ml/min
• Neutrophil count more than 1.5x 109 /L
• Platelet count more than 100x 109 /L
• Hemoglobin more than 8g/dL
• Before patient enrollment, written informed consent must be given according to Good Clinical Practice guidelines and national/local regulations.

Exclusion Criteria:

• Gastrointestinal bleeding
• Clinically relevant, symptomatic excessive amounts of ascites resulting in patient's discomfort
• CNS metastases
• Subject pregnant or breast feeding, or planning to become pregnant within 6 months after the end of treatment
• Subject (male or female) is not willing to use highly effective methods of contraception (per institutional standard) during treatment and for 6 months (male or female) after the end of treatment
• Known hypersensitivity reaction to the component of the treatment
• Active infection or malnutrition or bowel obstruction

• Medical or psychological condition which in the opinion of the investigator would not permit the subject to complete the study or sign meaningful informed consent
• Second primary tumor other than non-melanoma skin cancer or in situ cervical cancer
