The original policy of the Coalition for Epidemic Preparedness Innovations required that funded parties pre-register any trials in a clinical trials registry, publish results within a year of study completion (except with compelling reason and permission of CEPI), publish results in open-access articles, and have mechanisms for securely sharing underlying data and results, including negative results, in a way that preserves trial volunteer privacy. In May 2018 the CEPI proposed changing the policy to remove these provisions.[37] The policy was changed by the CEPI in December 2018.[38][39]
