Trial of Lapatinib Versus Lapatinib With Capecitabine in Her2+ Metastatic Gastro-Esophageal Cancer (GastroLap)

Lapatinib Versus Lapatinib With Capecitabine as Second-line Treatment in Her2-Overexpressing Metastatic Gastro-Esophageal Cancer: A Randomized Phase II Trial

Combining Erb inhibitors, such lapatinib, and TS inhibitors, such as capecitabine, may be a beneficial contribution to current treatment paradigms since preclinical data suggest that lapatinib alone can decrease TS mRNA and is synergistic with capecitabine in some cell lines, which may contribute to clinical benefit. The study described in this protocol has been designed to establish the anti-tumor activity of Lapatinib with or without capecitabine in the treatment of Her2 overexpressing metastatic gastric- and gastro-esophageal cancer, and to search for molecular correlates that may be associated with response to this compound.

The majority of patients with metastatic gastric and gastro-esophageal cancer undergo first-line combined chemotherapy (e.g. platin derivates and fluoropyrimidines, sometimes combined to a taxane), but the role of second-line chemotherapy has not yet been defined. Therefore, progression during or shortly after first-line chemotherapy is a medical condition no standard medical approach exists. The overexpression of EGFR and Her2 in gastric and gastroesophageal cancer make these indications prime candidate for treatment with the dual ErbB1/2 tyrosine kinase inhibitor (TKI) Lapatinib.

• At least one prior chemotherapy for metastatic disease with progression during or no later than 6 months after last administration of chemotherapy. Chemotherapy must have contained a platinum compound (cisplatin or oxaliplatin)
• Her2 overexpression measured by FISH (amplification or increased gene copy number). Immunohistochemistry (ICH) 3+ can be included in case of an uncertain FISH test.
• Patient willing to allow for biomarker analyses on his tumor tissue.
• Written informed consent given prior to any protocol specific procedures according to the local regulatory requirements
• Age >= 18 years
• Eastern Cooperative Oncology Group Performance Status (ECOG-PS) <= 2

Renal function: The calculated creatinine clearance should be .60 mL/min
• Eligibility of patients receiving medications or substances known to affect, or with the potential to affect the activity or pharmacokinetics of lapatinib will be determined following review of their use by the local Principal Investigator. A list of medications and substances known or with the potential to interact with CYP450 isoenzymes is provided in: Cytochrome P-450 Enzymes and Drug metabolism. In: Lacy CF, Armstrong LL, Goldman MP, Lance LL eds. Drug Information Handbook 8TH ed. Hudson, OH; LexiComp Inc. 2000: 1364-1371
• Able to swallow and retain oral medication
• Negative pregnancy test (urine or serum) within 28 days prior to randomization for all women of childbearing potential (has to be verified within 7 days prior to randomization and during the study according the judgement of the investigator)
• Willingness to perform double-barrier contraception during study and 6 months after end of treatment
• Ability to understand and the willingness to sign a written informed consent document
• Willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.

Exclusion Criteria:
