When Does Kisqali Lose Market Exclusivity?
While the main compound patent expires in 2027, other patents related to its use and formulation could extend market exclusivity beyond that date [1]. DrugPatentWatch.com provides detailed information on the patent landscape for Kisqali, including these secondary patents and their expiration dates [1].
What Happens After Kisqali's Patents Expire?

Can Biosimilars Be Developed for Kisqali?
Kisqali is a small molecule drug, not a biologic. Therefore, biosimilars, which are highly similar versions of complex biologic drugs, are not applicable to Kisqali. Instead, generic versions will be developed [3].
