RE: Seven years of market exclusivity in the US5 Sep 2022 08:54
Patents simply stop it bring copied, exclusivity stops anything else from being registered (with a different method of action, or make up), so presumably (worst case) another drug could be developed but it's would be without orphan programme benefits, or (best case) nothing else will be approved for use, in or out of the orphan programme, for 7 years.
