Clinical Trial Summary

This study will evaluate the disease free survival rate of a combination of capecitabine [Xeloda] and oxaliplatin (XELOX) with trastuzumab [Herceptin] in patients with resectable gastric cancer. The combination of Xeloda (orally, 1000 mg/m2 on day 1-14 of every cycle) and Herceptin (intravenously, 8 mg/kg loading dose, then 6 mg/kg on days 1-14 of every cycle) will be administered for three cycles prior to surgery to resect the tumor. If complete resection, R0 or microscopic residual tumor R1 is achieved, patients will continue with three cycles of XELOX and Herceptin and then for completion of 12 months treatment with Herceptin alone. Oxaliplatin will be administered intravenously at a dose of 130 mg/m2 on day 1 in every cycle. The anticipated time on study drug will be 12 months.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants With Disease-free Survival (DFS) at Month 18	DFS was the time elapsed from the time of surgery (for complete resection [R0] participants) until the date on which progression or death from any cause was documented (whichever occured first). Progression was defined as target lesions greater than (>) 20 percent (%) increase in the sum of the longest diameter (SLD) taking as reference the smallest SLD recorded since the treatment started (nadir) and minimum 5 millimeter (mm) increase over the nadir. When the sum becomes very small, increases within the measurement error (2-3 mm) can lead to a 20% increase. Participants who did not present progression and who had not died were censored on the last date on which it was known that there was no progression (last response assessment).	Month 18	No
Secondary	Percentage of Participants With Pathological Complete Response (pCR)	pCR was defined as an absence of any invasive cancer cell of the primary tumor after the time of major neoadjuvant chemotherapy, with or without surgery.	Between Days 7 and 21 of the 3rd cycle of neoadjuvant treatment, thereafter, every 9 weeks during adjuvant treatment and then after adjuvant treatment every 3 months until Month 25	No
Secondary	Percentage of Participants With Complete Tumor Resection (R0)	R0 resection was defined as having performed a complete resection of the tumor with adequate tumor-free margins and regional lymph node extirpation.	Between Days 7 and 21 of the 3rd cycle of neoadjuvant treatment, thereafter, every 9 weeks during adjuvant treatment and then after adjuvant treatment every 3 months until Month 25	No
Secondary	Percentage of Participants With Objective Response	An objective response was defined as either a complete response (CR) or a partial response (PR). Using the Response Evaluation Criteria in Solid Tumors (RECIST), CR was defined as the disappearance of all target lesions and all non-target lesions, normalization of tumor marker level, and no new lesions. PR was defined as the disappearance of all target lesions and persistence of greater than or equal to (=) 1 non-target lesions and/or the maintenance of tumor marker level above the normal limits, or, at least a 30% decrease in the sum of the longest diameter of target lesions, and no new lesions or unequivocal progression of existing non-target lesions.	Between Days 7 and 21 of the 3rd cycle of neoadjuvant treatment, thereafter, every 9 weeks during adjuvant treatment and then after adjuvant treatment every 3 months until Month 25	No
