• The 52 NASs approved by all six authorities in 2014-2018 were analysed according to orphan designation status as well as company. Out of the 52 NASs, only 10 NASs received an orphan designation across all the authorities, which may be due to differences in criteria for obtaining the designation within each agency, as well as the differences in the indication submitted by the sponsor and eventually approved.
• For EMA, 17 of the NASs were designated as orphan, compared with 28 for FDA, 21 for PMDA, 22 for Swissmedic and 20 for TGA. Health Canada does not have an orphan policy, however, this analysis considers NASs that were classified as orphan by either FDA, EMA or TGA and approved by Health Canada, with 29 NASs meeting such criteria.
• In general, the median submission gap for orphan NASs was longer compared with non-orphan NASs across all the authorities, which may be due to sponsor size. Indeed, the majority of orphan NASs were approved by non-top companies, highlighting the important role of smaller companies to drive innovation. On the other hand, the median approval timelines across all the agencies for orphan products were faster compared with non-orphans, which is likely due to the use of expedited pathways to prioritise the approval of such medicines.
