Selumetinib and Erlotinib Hydrochloride in Treating Patients With Locally Advanced or Metastatic Pancreatic Cancer

PRIMARY OBJECTIVES: l. To assess overall survival (as measured by median survival and proportion of patients alive at 24 weeks) in patients with advanced pancreatic cancer who have received one prior line of systemic therapy when treated with the combination of AZD6244 (selumetinib) and erlotinib (erlotinib hydrochloride). SECONDARY OBJECTIVES: I. Progression-free survival (median progression-free survival \[PFS\] and proportion of patients with PFS at 12 and 24 weeks). II. Cancer antigen (CA)19-9 biomarker response (defined as a 50% decline in serum CA19-9 level from baseline in patients with \> 2 x upper limit of normal \[ULN\] CA19-9 measurement). III. Objective radiographic response by Response Evaluation Criteria in Solid Tumors (RECIST) criteria. IV. Safety and toxicity profile of the combination of AZ6244 and erlotinib. OUTLINE: Patients receive selumetinib orally (PO) once daily (QD) and erlotinib hydrochloride PO QD on days 1-21. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 2-3 months.
