Genistein in Treating Patients With Pancreatic Cancer That Can Be Removed by Surgery

July 29, 2020 updated by: Jonsson Comprehensive Cancer Center

A Pre-Surgical, Randomized Clinical Trial of Genistein in Resectable Pancreatic Adenocarcinoma

RATIONALE: Genistein may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Giving genistein before surgery may be an effective treatment for pancreatic cancer.

PURPOSE: This randomized phase II trial is studying genistein to see how well it works in treating patients with pancreatic cancer that can be removed by surgery.

Detailed Description

OBJECTIVES:

Primary

  • To determine changes in microvessel density of the tumor specimen after 2 weeks of treatment with genistein in patients with resectable pancreatic adenocarcinoma.

Secondary

  • To evaluate the safety and tolerability of genistein in these patients by looking at the impact of genistein on pancreatic cancer angiogenesis and on the angiogenic factors VEGF, CXCL1, CXCL5, and CXCL8.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients receive neoadjuvant oral genistein once daily for 2 weeks in the absence of disease progression or unacceptable toxicity.
  • Arm II: Patients receive no specific neoadjuvant therapy. In both arms, patients undergo surgical resection in week 3.

Blood, urine, and tissue samples are collected at baseline and at the time of surgery for laboratory biomarker studies. Samples are analyzed for VEGF, CXCL1, CXCL5, and CXCL8 by ELISA and for genistein by mass spectrometry.

Description

Inclusion Criteria:

  • Adults over the age of 18 capable of giving informed consent

Exclusion criteria:

  • comorbid disease or medical condition that would impair the ability of the patient to receive or comply with the study protocol
  • hypersensitivity to genistein or to any of the excipients of genistein
  • prior chemotherapy or radiotherapy for pancreatic adenocarcinoma
  • concomitant use of warfarin, tamoxifen, or raloxifene.
  • pregnancy or inadequate contraception.
  • lactating females
