Administration, seeking approval to make a generic of Xeljanz, Tofacitinib, in 5- and 10-mg dosages.


Xeljanz is used to treat rheumatoid arthritis, psoriatic arthritis, and ulcerative colitis.


Pfizer sought the injunction order to prevent Aurobindo Pharma and its US arm from making and selling the drug in the US before its patent expiry.


Pfizer’s patents on the said drug set to expire in 2023 and 2025.
