METHOTREXATE, NDA 204824

The patents and exclusivities FDA's Orange Book lists for NDA 204824 as captured on 14 October 2026, each date named by its rule and its rows, and any rows of FDA's Paragraph IV list captured on 17 October 2026 that give this NDA's number. 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 204824, 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 204824.

Paragraph IV list rows giving NDA 204824

The rows of FDA's Paragraph IV certifications list as captured on 17 October 2026 whose RLD/NDA cell gives NDA 204824, each cell as listed.

Rows with no NDA number this page can match are kept apart on the list page; some may concern this product.

No row of the Paragraph IV list captured on 17 October 2026 gives NDA 204824 in its RLD/NDA cell. This does not mean no certification was submitted or that no application challenges a patent listed here.

Notes from the trace

  • R6 tentative approvals: not in the Orange Book data files as captured; the Drugs@FDA join is a later ruling.
