NCI National Clinical Trials Network (NCTN) Structure

The NCTN structure includes five U.S. Network groups and the Canadian Collaborating Clinical Trials Network. Membership in the individual NCTN groups is based on criteria that are specific to each group. Sites can belong to more than one group, and membership in at least one group allows a site to participate in the trials led by any NCTN group for which their investigators are qualified. Consequently, researchers from the LAPS, NCORP, other academic centers, community practices, and international members associated with the Network groups may all enroll patients onto NCTN trials. Clinical trials led by NCTN groups may receive support from the IROC Group, ITSAs, and tissue banks, according to the scientific needs of the trials.
