Objective Response Rate (ORR) [ Time Frame: one year ]
The primary endpoint is the ORR within the first 6 treatment cycles, defined as the percentage of participants with a confirmed reduction in tumor size fulfilling the criteria for complete or partial response (CR or PR) according to RECIST. CR=disappearance of all target lesions, PR=30% decrease in the sum of the longest dimensions of the target lesions taking as a reference the baseline sum longest dimensions

Descriptive Information
Brief Title  ICMJE Efficacy and Safety of Sunitinib in Metastatic Gastric Cancer
Official Title  ICMJE An Open-label, Multicenter Phase II Trial of Sunitinib for Patients With Chemo-refractory Metastatic Gastric Cancer
Brief Summary

This trial will be conducted to evaluate the efficacy, safety, and tolerability of sunitinib (sunitinib-malate) as a second-line palliative therapy in metastatic gastric cancer. Despite the efforts in front-line therapy, second-line protocols have not yet been established in randomized clinical trials for those patients. Although many patients are still in good performance status and present with low tumor burden after failure of first-line chemotherapy, they may clearly benefit from second-line treatment. Increasingly more metachronic metastatic patients are urging for new platinum-free therapeutic options due to the fast-growing use of (neo-) adjuvant platin-based protocols.

So far, only sparse data on chemotherapy are available after failure of platin-based protocols. Nearly only irinotecan-containing combinations have properly been analyzed, and produced excellent response rates and survival times of up to 30% and 7.6 months, respectively. However, irinotecan has not been approved yet for this indication. In addition, as irinotecan-containing regimens have been submitted for approval for first-line therapy, second-line regimens in irinotecan-refractory patients have not been evaluated in any trial. Thus, there is an urgent need to establish new second-line treatment options for both, cisplatinum- or irinotecan-combination refractory patients with advanced or metastatic gastric cancer.

Sunitinib inhibits the receptor tyrosine kinases (RTKs) involved in tumor proliferation and angiogenesis, specifically the VEGFR, PDGFR, KIT, FLT-3, and RET. The VEGF pathway has been shown to be a significant factor in metastatic gastric cancer. In gastric carcinoma cells, VEGF ligands and its receptors are definitely involved in the process of tumor progression. KDR and FLT-1 are expressed widely and VEGF stimulated KDR-positive tumor cell growth directly. The ligand VEGF-C has also been shown to be involved in progression of human gastric carcinoma, particularly via lymphangiogenesis. In addition, peritoneal metastases of some cancers such as gastric cancers were largely dependent on VEGF. Therefore, patients with chemo-refractory metastatic gastric cancer might benefit from VEGFR inhibitory therapy with sunitinib.

Eligibility Criteria  ICMJE

Inclusion Criteria:

  • Signed and dated informed consent of the patient before the start of specific protocol procedures
  • Histologically proven adenocarcinoma of stomach, esophagogastric junction or lower esophagus (Barrett carcinoma)
  • Measurable metastatic disease according to the Response Evaluation Criteria in Solid Tumors (RECIST). If locally recurrent disease, it must be associated with at least one measurable lymph node (> 20 mm by computed tomography [CT] scan or > 10 mm with spiral CT).
  • Failure of prior palliative chemotherapy/chemotherapies (at least one irinotecan- or cisplatin-based). Failure is defined either by progression of disease or by significant toxicity that precludes further treatment.
  • At least 3 weeks from previous chemotherapy at first dose of trial drug
  • Resolution of all acute toxic side effects of prior therapy or surgical procedures to grade ≤ 1 National Cancer Institute-Common Toxicity Criteria (NCI-CTC) (except for the laboratory values)
  • Adequate organ function as defined by the following criteria:

    • Serum aspartate transaminase (AST; serum glutamic oxaloacetic transaminase [SGOT]) and serum alanine transaminase (ALT; serum glutamic pyruvic transaminase [SGPT]) ≤ 2.5 x upper limit of normal (ULN), or AST and ALT ≤ 5 x ULN if liver function abnormalities are due to underlying malignancy
    • Total serum bilirubin ≤ 1.5 x ULN
    • Absolute neutrophil count (ANC) ≥1500/microL
