What is the scale factor of the smaller prism to the larger prism?
Ensuring patient safety is a priority - FDA must determine that the potential patient benefit justifies the potential risk of the expanded access use of the investigational drug, and that the potential risk is not unreasonable in the context of the disease or condition to be treated. UVM PIs with approved SARE projects that will conduct research that includes human subjects are required to submit their projects to the UVM IRB for either a formal exemption determination or research protocol approval.
