• For Group 1, patients who are HER 2 positive.
• Any other concurrent uncontrolled illness including, but not limited to, active or ongoing symptomatic infection requiring IV antibiotic treatment, uncontrolled diabetes, hepatic, renal, or respiratory illness.
• Severe or unstable angina, myocardial infarction or ischemia, symptomatic congestive heart failure, arterial or venous thromboembolism requiring coronary artery bypass graft or stent within the past 6 months or clinically significant cardiac dysrhythmia or New York Heart Association class II ~ IV heart disease within 6 months of randomization.

Group 1	IDX-1197+XELOX	-
Group 2	IDX-1197+Irinotecan	-

Primary Outcome Measures

Name	Time	Method
Maximum Tolerated Dose (MTD) and Recommended Phase 2 Dose (RP2D)	through study completion (Up to 12 months)	To determine the MTD and RP2D of IDX-1197 when given in combination with XELOX or Irinotecan. This will be accomplished by the standard 3+3 dose escalation design. If 2 of the 3 to 6 patients in a particular dose level experience a DLT, the dose escalation should be stopped at this dose level, and the MTD will be determined.
Dose Limiting Toxicities (DLTs)	during the first 21-day cycle for Group 1 and through first 2 cycles (14 days each) for Group 2	Occurrence of DLTs
