The Agency provided recommendations specific to the moderate to severe chronic plaque psoriasis sNDA.

About XELJANZ

XELJANZ (tofacitinib citrate) is a prescription medicine called a Janus kinase (JAK) Inhibitor.

XELJANZ is the first and only JAK inhibitor approved in over 40 countries around the world for the treatment of moderate to severe rheumatoid arthritis (RA) as a second-line therapy after failure of one or more disease-modifying antirheumatic drugs (DMARDs). The clinical profile of XELJANZ in RA has been studied in approximately 6,200 patients with approximately 16,800 patient-years of drug exposure in the global clinical development program for XELJANZ in moderate to severe RA.

Pfizer is committed to advancing the science of JAK inhibition and enhancing understanding of XELJANZ through a robust clinical development program in a range of immune-mediated inflammatory conditions in the areas of rheumatology, dermatology and gastroenterology.
