CNTN Executive Committee

The CNTN/RCEN Executive Committee, was established to review and provide feedback to investigators on their proposed trials, and subsequently to facilitate the conduct of multi-center clinical trials in nephrology. This Committee is comprised of Canadian experts in randomized trial methodology and conduct. They can provide feedback to investigators at any stage of the trial proposal, offering suggestions on how to improve the methodology with the goal of increasing success of peer-reviewed funding. In addition, this Committee has developed a network of participating clinical trial sites that can be contacted by investigators for patient recruitment.

The committee thus offers three types of support to investigators:

  • Brief review by one committee member with feedback
  • Formal review by 2 reviewers and discussion with entire committee, with potential for Letter of Endorsement that can be sent to funding agencies
  • Facilitation of sites for multi-centre trials
