 Additional safety data will be collected from the first patient imaged from each of the first three batches of FDG delivered to our clinical site N3. The chemical structure of our product is identical to authentic FDG. We have performed a minimum of five consecutive 18F-FDG productions with all quality control passing and will have done many more in the course of this CTA review process. The safety record of FDG PET worldwide is undisputable and we expect the number of adverse events in our study to be zero. In addition to baseline assessment, these subjects will have their blood pressure, oxygen saturation, heart rate and temperature monitored every 15 minutes for 2 hours post-procedure. Patients will be questioned as to their general well-being after the scan. If there are concerns that the patients health status has changed during or immediately following the scan, then a physician will provide a more detailed assessment. Each of these three patients will be followed up by telephone, usually the day after the scan to help insure there were no delayed effects. These whole body PET scan images will be reviewed independently by two Nuclear Medicine physicians to confirm an expected biodistribution of radioactivity. If a subject did experience a reaction post-injection that could not immediately be attributed to another condition or exposure, or if the biodistribution of FDG in normal tissue was altered and could not be explained on clinical grounds eg. patient on G-CSF, the tracer would be re-examined and tested for impurities and pyrogens. The safety data collected from these three patients will verify that the FDG produced by the BCCA is behaving as expected.
