Abstract

Background: The objective of this study was to assess the differential times of submission and approval of CFTR modulators in the United States (US) and the European Union (EU).<br />Methods: By collecting publicly available data from the websites of the Food and Drug Administration and the European Medicines Agency, we quantified differential times in submission, review duration, and approvals of initial marketing authorization and variation of indications of CFTR modulators in the US and the EU by December 31, 2023.<br />Results: Applications regarding marketing of 4 CFTR modulators were submitted 103 (SD ±143) days later in the EU than in the US: 31 (SD ±39) days later for initial approval, and 124 (SD ±155) days for supplemental indications. The regulatory review process was completed in 181 days [IQR, 179 - 182] in the US and 325 days [IQR, 276 - 382] in the EU: 167 days [IQR, 102 - 232] in the US and 346 days [IQR, 302 - 400] in the EU for first approvals, 181 days [IQR, 181 - 182] in the US and 324 days [IQR, 264 - 382] in the EU for supplemental indication approvals. CFTR modulators were approved 267 (SD 143) days later in the EU than in the US: 220 (SD ±76) days for initial approval and 280 (SD ±157) days for supplemental indications.<br />Conclusion: We found significant differences in times of submission and for approval of CFTR modulators between the US and EU, whereby initial approvals and subsequent indication approvals were always first granted in the US.<br />Competing Interests: Declaration of competing interest Enrico Costa - Member of the Committee for Orphan Medicinal Products (COMP) at the EMA.
