Data Sharing Requests

Per National Cancer Institute's National Clinical Trials Network (NCTN) guidelines, any investigator may submit a request for data from published Alliance or legacy American College of Surgeons Oncology Group (ACOSOG), Cancer and Leukemia Group B (CALGB), or North Central Cancer Treatment Group (NCCTG) trials.

To submit a data request, the investigator should complete an Alliance Data Sharing Request Form and send it by e-mail to concepts@allianceNCTN.org. Once received, the request will be forwarded to the Alliance Statistics and Data Center (SDC). The SDC will confirm the availability of the data. Once the SDC confirms availability, the investigator will be asked to provide documentation of Institutional Review Board (IRB) approval or exemption from their institution, as well as to submit an Alliance Data Release Agreement. Once the IRB documentation and the data release agreement are received from the requesting investigator, the SDC will be notified that the requested data may be released.
