  Purpose

Study Design:

This is a single institution pilot study to recruit 4 patients with operable pancreatic cancer scheduled for a pancreatectomy and 4 age/sex matched normal controls. Both groups will receive a single oral dose of radiolabeled MelQx followed by serial blood draws over an 8 hour period and urine collections over a 24 hour period. In addition, normal pancreatic tissue and normal small bowel tissue will be collected by Tissue Procurement from resected (waste) tissue at the time of pancreatectomy on the 4 pancreatic cancer patients.

Primary Outcome Measures:
  • Pharmacokinetic Metabolite Profile of Radiolabeled MeIQx in Blood [ Time Frame: Pre MeIQx Administration, 1/2, 1, 2, 4, 6, 8 Hours Post MeIQx Administration ] [ Designated as safety issue: No ]
    Metabolite levels will be expressed as the percent of total recovered radioactivity in plasma. Metabolite profiles will be qualitatively compared between cases and controls, which will include the mean, median, standard deviation, range and 90% confidence interval for the major detoxification metabolites.

  • Pharmacokinetic Metabolite Profile of Radiolabeled MeIQx in Urine [ Time Frame: 0-4, 4-8 and 8-24 Hours Post MeIQx Administration ] [ Designated as safety issue: No ]
    Metabolite levels will be expressed as the percent of total recovered radioactivity in urine. Metabolite profiles will be qualitatively compared between cases and controls, which will include the mean, median, standard deviation, range and 90% confidence interval for the major detoxification metabolites.


Secondary Outcome Measures:
  • Quantify [14C]MeIQx-DNA adducts in human pancreas [ Time Frame: 4-8 Hours Post MeIQx Administration ] [ Designated as safety issue: No ]
    In the pancreatic cancer patients, uninvolved/normal resected (waste) tissue from the surgery will be sent to Lawrence Livermore National Laboratory (LLNL) for DNA extraction following previously published methods. New [14C]MeIQx-DNA adducts formed at physiological concentrations will be detected and quantified in resected tissue with highly sensitive accelerator mass spectrometry (AMS).

  • Quantify ambient adducts in the human pancreas [ Time Frame: 4-8 Hours Post Administration ] [ Designated as safety issue: No ]
    DNA adducts already present in resected tissue will be quantified and characterized with a newly improved technique, electrospray capillary high performance liquid chromatography-tandem mass spectrometry (LC-MS/MS).

Arms Assigned Interventions
Active Comparator: Healthy Control Participants
age/sex matched normal controls - the subject will swallow a capsule with a dietary relevant dose of MeIQx
Radiation: MeIQx
On the day of administration, the subject will swallow a capsule with a dietary relevant dose of MeIQx, 21 µg, labeled with a very low level of 14-carbon. The radioactive dose for MeIQx, 0.002 mSv (4.3 µCi), or less than an average dental x-ray.
Other Name: [14C]-MeIQx (2 Amino-3,8-dimethylimidazo[4,5 f]quinoxaline-2-[14C])
Active Comparator: Pancreatic Cancer Patients
Patients with operable pancreatic cancer scheduled for a pancreatectomy at the University of Minnesota Medical Center.
Radiation: MeIQx

Detailed Description:

This is not a therapeutic trial. It is an etiologic investigation of meat-borne carcinogens and possible role in pancreatic cancer.
