Descriptive Information
Brief Title  ICMJE Targeted PARP or MEK/ERK Inhibition in Patients With Pancreatic Cancer
Official Title  ICMJE A Window of Opportunity Strategy for Targeted PARP or MEK/ERK Inhibition in Patients With Pancreatic Ductal Adenocarcinoma
Brief Summary This phase II trial feasibility study aims to determine how cobimetinib or olaparib works in patients with pancreatic cancer. Validation of cobimetinib and olaparib molecular targets will be explored by comparing pre-treatment biopsies with post-treatment specimens. This knowledge will help design future biomarker driven trials to determine whether giving cobimetinib plus olaparib will work better than standard treatments in patients with pancreatic cancer.
Detailed Description

PRIMARY OBJECTIVE:

I. Assess the feasibility of collecting tumor tissue for biomarker evaluation prior to and after window therapy with either cobimetinib or olaparib.

SECONDARY OBJECTIVES:

I. Assess preliminary safety and tolerability of cobimetinib. II. Assess preliminary safety and tolerability of olaparib.

EXPLORATORY OBJECTIVES:

I. Identify predictive biomarkers of sensitivity to cobimetinib or olaparib. II. Identify emerging mechanism(s) of resistance to cobimetinib or olaparib. III. Determine cellular and molecular changes in pancreatic tumor cells exposed to cobimetinib or olaparib.

IV. Identify tumor markers suggestive of combinatorial therapy that could overcome resistance to therapy.

OUTLINE: Patients are assigned to 1 of 2 arms.

ARM I: Patients receive cobimetinib orally (PO) once daily (QD) on days 1-10 in the absence of disease progression or unacceptable toxicity. Within 12-24 hours, patients undergo biopsy or surgery as clinically appropriate per institutional standards for management of patient's disease.

ARM II: Patients receive olaparib PO twice daily (BID) on days 1-10 in the absence of disease progression or unacceptable toxicity. Within 12-24 hours, patients undergo biopsy or surgery as clinically appropriate per institutional standards for management of patient's disease.

After completion of study treatment, patients are followed up for 30 days.

Inclusion Criteria:

  • Ability to understand and the willingness to sign a written informed consent document

  • Clinically-confirmed diagnosis of adenocarcinoma of the pancreas (resectable, borderline resectable, locally advanced, or metastatic disease at presentation) are eligible
  • Participants may be treatment naive or have received prior therapy for the treatment of their PDAC. A minimum washout period of 10-days after completing the most recent line of therapy is required before a participant can initiate treatment with study agent (i.e., cobimetinib or olaparib)
  • Based on available imaging, participant must have at least one disease lesion that can be biopsied in accordance with institutional standards
  • Hemoglobin >= 10.0 g/dL with no blood transfusion within 28 days of starting treatment (at time of registration and within 4 weeks prior to initiating window treatment)
