Data and Sample Requests
There are two ways to access data and samples from the DCCT/EDIC Study. One is via the NIDDK Repositories, which have data and samples available for distribution through 2011. The second is to apply to collaborate with the EDIC Study. Using the resources below, investigators should first evaluate whether the data and biological specimens required for the research can be provided by the NIDDK Repositories, and if so, the application for access to that material should be submitted to the Repositories, not to the DCCT/EDIC study group. However, if the research requires access to data and/or biological materials that are not available in the NIDDK Repositories, the investigator can submit an application to EDIC using the processes described below.
Accessing data and samples via the NIDDK Repository
For non-renewable samples, you must be granted access through a peer-reviewed application process, either via PAR-11-306, PAR-13-228 or PAR-14-257. See the individual announcements and www.niddkrepository.org for more information.
Collaborating with the EDIC Study
All collaborators should agree to the EDIC Publications and Presentations Policy and the Ancillary Studies Policies that are contained in Chapter 8 of the EDIC Protocol.

- EDIC Publication and Presentations Committee Procedures

Prospective investigators should be aware that there is a finite quantity of specimens in both the EDIC Central Biochemistry Laboratory (CBL) and the NIDDK Repository, and some samples may have been depleted or may have very low volumes. Therefore, a sample of subjects with available specimens may be a biased representation of the DCCT/EDIC cohort. Availiability of adequate numbers of subjects with available specimens will be a criteria on which the Research Review Committee (RRC) will base their evaluations of a new proposal.
*Potential collaborators may require information to allow them to best evaluate the possibilities for collaborations with EDIC or to plan the design (e.g. sample size) for a study. Investigators who would like to obtain specific numbers of cases of specific outcomes that have occurred during EDIC should contact Ms. Patricia A. Cleary at email@example.com.
