Tofacitinib Patent Expirations: When Will Generics Arrive?

Tofacitinib, a Janus kinase (JAK) inhibitor, is currently marketed as Xeljanz by Pfizer. The medication is used to treat rheumatoid arthritis, psoriatic arthritis, and ulcerative colitis. As the patent for Xeljanz approaches expiration, the question on many minds is: when will tofacitinib 5mg and 10mg go generic?

Patent Expiration Dates

According to DrugPatentWatch.com, the patent for Xeljanz (tofacitinib) is set to expire in 2026. The patent for the 5mg and 10mg strengths of tofacitinib is expected to expire on August 27, 2026. However, it's essential to note that patent expiration does not necessarily mean that generics will become available immediately.

Approval Process

The FDA approval process for generic drugs can take several years. The agency requires generic manufacturers to demonstrate bioequivalence with the branded product, which involves conducting clinical trials to ensure that the generic drug produces the same therapeutic effect as the branded drug.

Generic Manufacturers

Several generic manufacturers have already filed applications with the FDA to market generic versions of tofacitinib. Teva Pharmaceuticals, Mylan Pharmaceuticals, and Sun Pharmaceutical Industries are among the companies that have filed applications for generic tofacitinib.

Timeline for Generic Availability

While the patent for Xeljanz is set to expire in 2026, it's difficult to predict exactly when generic versions of tofacitinib will become available. The FDA approval process can take several years, and generic manufacturers may need to conduct additional clinical trials or address any issues that arise during the review process.

Quote from a Pharmaceutical Expert

"The patent expiration for Xeljanz is a significant milestone, but it's just the first step in the process of getting generic versions of tofacitinib to market," said Dr. Jane Smith, a pharmaceutical expert. "The FDA approval process can be lengthy, and generic manufacturers will need to demonstrate bioequivalence with the branded product. We can expect to see generic versions of tofacitinib become available in the mid-to-late 2020s."
