Share All Cancer Drug Approval Data: Study
Researchers in the U.S. and Australia say that while there has been a substantial increase in individual participant data (IPD) sharing for industry-sponsored oncology trials in the past five years, much more needs to be done. An investigation published in JAMA Oncology found that of the 304 trials that underpinned FDA registration of 115 anticancer medicines over the past 10 years, 45% were eligible for IPD sharing but 55% were not eligible.
“Although inroads have been made toward improving IPD transparency over the past five years,” the article says, “these findings suggest that a substantial portion of pivotal oncology trials that support the FDA registration of modern anticancer medicines remain unavailable to qualified researchers…. Because these trials form the basis of safety and efficacy claims for new medicines, we question whether it is justified that the data are unavailable to independent scrutiny. On the basis of our findings, we reiterate calls that transparency policies need updating so that all IPD that inform results presented in a product label or underpin drug registration are immediately eligible for sharing.”
