When medicines are granted a Conditional Marketing Authorisation (CMA) in Europe, specific obligations are requested to obtain comprehensive data on benefits and risks. We performed a retrospective cohort study to characterize obligations, examine changes to their description and due dates after initial authorization, determine timing of data submission relative to due dates, and identify drug-related, procedure-related, and obligation-related factors associated with change. We identified 69 obligations for 26 medicines conditionally authorized between 2006 and 2016. We found 39 changes to 27 obligations (39% of obligations), of which four substantially changed the obligation. For 55% of obligations, data submission was delayed. Eleven factors were associated with change, including the use of CMA as a rescue option. The results are potentially indicative of a continuous search by regulators to reduce uncertainties. Submission delays impact public health negatively by prolonging exposure of patients to unknown risks, particularly when the level of uncertainty is high.
