Children’s Oncology Group Data Sharing Statement:
The Children’s Oncology Group Data Sharing policy describes the release
and use of COG individual subject data for use in research projects in
accordance with National Clinical Trials Network (NCTN) Program and NCI
Community Oncology Research Program (NCORP) Guidelines. Only data
expressly released from the oversight of the relevant COG Data and
Safety Monitoring Committee (DSMC) are available to be shared. Data
sharing will ordinarily be considered only after the primary study
manuscript is accepted for publication. For phase 3 studies,
individual-level de-identified datasets that would be sufficient to
reproduce results provided in a publication containing the primary study
analysis can be requested from the NCTN/NCORP Data Archive at
https://nctn-data-archive.nci.nih.gov/. Data are available to
researchers who wish to analyze the data in secondary studies to enhance
the public health benefit of the original work and agree to the terms
and conditions of use. For non-phase 3 studies, data are available
following the primary publication. An individual-level de-identified
dataset containing the variables analyzed in the primary results paper
can be expected to be available upon request. Requests for access to COG
protocol research data should be sent to:
datarequest@childrensoncologygroup.org. Data are available to
researchers whose proposed analysis is found by COG to be feasible and
of scientific merit and who agree to the terms and conditions of use.
For all requests, no other study documents, including the protocol, will
be made available and no end date exists for requests. In addition to
above, release of data collected in a clinical trial conducted under a
binding collaborative agreement between COG or the NCI Cancer Therapy
Evaluation Program (CTEP) and a pharmaceutical/biotechnology company
must comply with the data sharing terms of the binding
collaborative/contractual agreement and must receive the proper
approvals.
