For Clinical Trials

The CTC highly recommends that any company/team developing a trial, request to meet with the CTC early in the development stage of their trial. Email Jayne Dixon Weber for more information. Once the trial has been approved by the CTC, the NFXF will provide the list of Frequently Asked Questions (FAQs) for the company to complete, and will proceed with the website posting.
