Trial Outcomes & Findings for Study of 5-FU, Oxaliplatin, & Lapatinib Combined With Radiation Therapy to Treat HER2 Positive Esophagogastric Cancer (NCT NCT01769508)

NCT ID: NCT01769508

Last Updated: 2016-06-13

Results Overview

Defined as the absence of invasive tumor in esophagogastric and lymph node tissue removed at time of surgery, as judged by the local pathologist. An improvement in pCR rate from 30 percent (historical) to 50 percent is the primary efficacy endpoint.

SECONDARY outcome

Timeframe: 18 months

Time to progression is defined as the time between day 1 cycle 1 and time to first documented disease progression. Disease progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.
