• The patient has either (a) measurable disease as defined by Response Evaluation Criteria in Solid Tumors (RECIST) (see Section 11.3) or (b) non-measurable disease with an elevated baseline CA19-9 level (≥2 x the upper limit of normal [ULN]).
• The patient's ECOG performance status is ≤2.
• The patient has adequate hematologic function as defined by an absolute neutrophil count (ANC) ≥1500/mm3 and a platelet count ≥100,000/mm3 obtained within 2 weeks prior to the first dose of study medication.
• The patient has adequate hepatic function as defined by a total bilirubin ≤2.0 mg/dL and transaminases ≤5.0 x ULN obtained within 2 weeks prior to the first dose of study medication.
• The patient has adequate renal function as defined by serum creatinine ≤2.0 x ULN and urine dipstick for proteinuria ≤1+ obtained within 2 weeks prior to the first dose of study medication. If urine dipstick is ≥2+, then a 24-hour urine for protein must demonstrate < 1000 mg of protein in 24 hours to allow participation in the study. Urinalysis is also acceptable.

• If the patient is on full-dose anticoagulation therapy (eg, warfarin or low molecular weight [LMW] heparin), the following criteria must be met:

  • The patient has an in-range INR (usually between 2 and 3) on a stable dose of oral anticoagulant or be on a stable dose of LMW heparin
  • The patient has no active bleeding or pathological condition that carries a high risk of bleeding (e.g., tumor involving major vessels or known varices)

• If the patient is not on full-dose anticoagulation therapy, the following criteria must be met:

  • The patient has adequate coagulation function as defined by INR ≤1.5
  • The patient has a PTT ≤ULN obtained within 2 weeks prior to the first dose of study medication
• If a woman, the patient agrees to use an accepted and effective method of contraception (hormonal or barrier methods, abstinence) prior to study entry and for the duration of the study. If a male and sexually active, the patient agrees to use effective contraception.
• The patient is accessible for treatment and follow-up. Patients enrolled in this trial must be treated at the participating center.
