NCT ID: NCT00193063

Last Updated: 2014-03-12

Results Overview

The Percentage of Patients Who Experience an Objective Benefit From Treatment. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI or CT: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.

Measure
Gemcitabine/Trastuzumab
All patients entering this trial received treatment with a combination of gemcitabine and trastuzumab. Gemcitabine 1000 mg/m2 was administered intravenously on days 1, 8,and 15 of a 28-day cycle. Trastuzumab was administered as a 4 mg/kg intravenous loading dose on day 1 and subsequently at a dose of 2 mg/kg on a weekly basis.

SECONDARY outcome

Timeframe: 21 Months

The Length of Time, in Months, That Patients Were Alive From Their First Date of Protocol Treatment Until Worsening of Their 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.
