When does the Novartis patent for Tasigna (nilotinib) expire? Novartis’ primary patent covering Tasigna, which claims the chemical composition and use of nilotinib, expires on 31 December 2024【1】. What happens after the patent expires? Once the patent lapses, other manufacturers may develop and market biosimilar or generic versions of nilotinib, subject to regulatory approval. The drug will then enter a competitive pricing environment, potentially lowering costs for patients and insurers. How long did the exclusivity period last? The original patent filing was in 2006, giving it an 18‑year term (standard in the U.S.) plus any additional time for regulatory exclusivity granted by the FDA. The 2024 expiration reflects the standard 18‑year life from filing. Who holds the patent and are there other related patents? Novartis holds the key composition‑of‑matter patent, but there are additional patents on formulations, delivery systems, and manufacturing processes that may extend market protection in certain regions. However, the main composition patent expires in 2024【1】. When can competitors expect to launch generic versions? Generic manufacturers must first obtain FDA approval, which typically occurs after the patent expires or if a court allows earlier entry. With the 2024 expiry, it is feasible that generics could appear in the market by 2025–2026, depending on regulatory timelines. Is there a risk of litigation before the patent expires? Some companies have challenged Novartis’ patents in the past. If a court finds a patent invalid or unpatented, competitors could seek market entry sooner. As of now, no major litigation is pending that would alter the 2024 expiration date【1】. Where can I find more detailed patent information?
