DOTATOC PET/CT for Imaging NET Patients

DOTATOC PET/CT for Imaging NET Patients

Official Title

Evaluation of the Safety and Sensitivity of 68Ga-DOTATOC PET/CT for Imaging NET Patients

Brief Summary

      Neuroendocrine tumours (NETs) are generally slow growing, but some can be aggressive and
      resistant to treatment. Compared to healthy cells, the surface of these tumor cells has a
      greater number of special molecules called somatostatin receptors (SSTR). Somatostatin
      receptor scintigraphy and conventional imaging are used to detect NETs.

      This study proposes 68Gallium(68Ga)-DOTATOC positron emission tomography/computed tomography
      (PET/CT) is superior to current imaging techniques. The goal is to evaluate the safety and
      sensitivity of 68Ga-DOTATOC PET/CT at detecting NETs and other tumors with over-expression of
      somatostatin receptors.
    

Detailed Description

      Each subject will have two PET/CT scans, one using 68Ga-DOTATOC and the other using
      18-Fluoride-Fluorodeoxyglucose (18F-FDG). The 68Ga-DOTATOC radioactive tracer is manufactured
      for this study under a Clinical Trial Application filed with Health Canada. 18F-FDG is
      considered standard care and has been approved by Health Canada.

      After providing informed written consent subjects will complete a medical history
      questionnaire.

      Monitoring of adverse events There will be short-term evaluation of adverse events by
      comparison of vital signs before and after administration of 68Ga-DOTATOC. Twenty-four hours
      after 68Ga-DOTATOC administration the study coordinator will call the patient and see if they
      have experienced any adverse events during that time period and complete the adverse event
      questionnaire found in section 9.6.

      Follow-up Assessments

      The following information will be collected up to 3 years following the PET/CT scans:

        -  Initiation of a new treatment

        -  Laboratory results and pathology reports

        -  Results of imaging studies

        -  Final clinical diagnosis by physician and relevant clinical notes

      The study is expected to take approximately 4 years for accrual.
