MIGALASTAT HYDROCHLORIDE, NDA 208623
The patents and exclusivities FDA's Orange Book lists for NDA 208623 as captured on 14 October 2026, each date named by its rule and its rows, and the rows of FDA's Paragraph IV list that give this NDA's number, as captured on 17 October 2026. Listed protection is a range of dates, never one date.
FDA capture · review pending. Each row is shown as captured from FDA's Orange Book files and Paragraph IV list. Dates are FDA's own; spreadsheet day numbers are shown as dates, and a cell that cannot be read as one date is shown as written and left out of the range. Where FDA lists a *PED row without flags, its flags are read from the base row and marked so. A Paragraph IV row is placed here only by the number in its RLD/NDA cell; nothing is joined by name. How this page reads FDA's files has not been independently reviewed by a regulatory-affairs reviewer.

Listed protection is a range of the dates FDA lists, not a forecast of market entry, and not legal, regulatory or investment advice.
Dates as listed in FDA's Orange Book capture of 14 October 2026. This page does not say whether a date has passed; compare it with today's date and FDA's current Orange Book. This page shows only what the capture of 14 October 2026 lists. It does not show patents or exclusivities listed before and since removed.

Listed exclusivities
Each exclusivity FDA lists for NDA 208623, with its code, FDA's definition of the code where the store's code list gives one, and its date as listed.
The Orange Book capture of 14 October 2026 lists no exclusivity for NDA 208623.
Paragraph IV list rows giving NDA 208623
The rows of FDA's Paragraph IV certifications list as captured on 17 October 2026 whose RLD/NDA cell gives NDA 208623, each cell as listed.
FDA's Paragraph IV list names no patent number, so it does not say which of the patents on this page an applicant certified against.
The list gives the last qualifying patent's expiry without pediatric exclusivity; in the app's Patents view, the Orange Book lists any *PED period as a separate row with its own date. The two dates describe different things. A blank cell is one FDA left blank in its list. Dates are FDA's own; the last qualifying patent expiry is not recomputed from the Orange Book.
Rows whose RLD/NDA cell we could not read as exactly one NDA number are kept apart on the list page; some may concern this product.
