Objective To describe early experience with sharing clinical research data through the Yale University Open Data Access (YODA) Project.

Design Cross-sectional analysis of all submitted proposals by investigators to use clinical research data being made available by Johnson & Johnson (J & J) through the YODA Project, since the inception of the initiative in October 2014, including approval, data access, and publication status.

Results Of the clinical trials conducted by J & J, to date, 189 trials have been reviewed by J & J and determined to be available for sharing with external investigators, most commonly of therapies used for the treatment of bipolar disorder and schizophrenia. In addition to 1 medical device trial and 188 pharmaceutical trials, J & J continues to review trials for eligibility, and additional trials can be made available on request, including trials of consumer products. As of June 2017, the YODA Project had received 73 proposals from external investigators to use data from 159 trials; the median number of trials requested was 3 (interquartile range [IQR], 1-9; maximum, 50). Among the 73 proposals, 65 (89.0%) have been approved by an independent review panel and 2 (2.8%) are under review; 6 (8.2%) were withdrawn or closed owing to patient privacy concerns, unavailability of needed data elements, or lack of research proposal clarity. The most common study purposes proposed were to address secondary research questions (n = 39), combine data as part of larger meta-analyses (n = 35), and/or validate previously published studies (n = 17). Of the 65 approved proposals, 50 researchers have access to the data and are working on their projects (median duration of access, 43.7 weeks; IQR, 21.0-71.5), 8 are awaiting execution of their Data Use Agreement or data preparation, and 5 have completed their projects, 2 of which resulted in publications in the peer-reviewed literature, and 3 of which have submitted a manuscript for publication. In both cases, the final publication represented the originally proposed research. The authors of the remaining 2 proposals did not pursue their projects.

Conclusions Early experience sharing data through the YODA Project has demonstrated a demand for shared clinical research data as a resource for investigators. As trial funders and investigators increasingly share data, and make use of shared data, it is essential to understand best practices and incentives to ensure success.
