Xiidra, a prescription eye drop used to treat dry eye disease, is not expected to have a generic version available in 2026. The current patent exclusivity for Xiidra is anticipated to extend beyond that year.
When does Xiidra's patent exclusivity end?
DrugPatentWatch.com data indicates that the primary patents protecting Xiidra are set to expire in 2030 [1]. This means that generic manufacturers are unlikely to be able to launch their versions of the drug before this date, barring any successful patent challenges or settlements.
What happens if Xiidra patents are challenged?
While the current patent landscape suggests 2030 for generic availability, patent litigation can alter these timelines. If a patent is successfully challenged and invalidated, or if a settlement is reached between the brand manufacturer and a generic company, a generic version could potentially become available sooner than 2030. However, such outcomes are not guaranteed and depend on the legal proceedings.
Can biosimilars enter before patent expiry?
Xiidra is a small molecule drug, not a biologic. Therefore, biosimilars, which are versions of biologic drugs, are not applicable to Xiidra. The potential for generic competition for Xiidra falls under small molecule generic drug pathways.
How does Xiidra work to treat dry eye disease?
Xiidra works by inhibiting the T-cell binding of leukocyte function-associated antigen-1 (LFA-1) to intercellular adhesion molecule-1 (ICAM-1). This interaction plays a role in the inflammatory process that can contribute to dry eye disease [2]. By reducing this inflammation, Xiidra aims to improve the signs and symptoms of dry eye.
What are the alternatives to Xiidra for dry eye disease?
Several other prescription and over-the-counter treatments are available for dry eye disease. These include artificial tears, prescription eye drops like cyclosporine (Restasis, Cequa) and lifitegrast (also the active ingredient in Xiidra), and punctal plugs. The best treatment approach depends on the individual's specific condition and the underlying causes of their dry eye.
What is the cost of Xiidra?
The cost of Xiidra can vary depending on insurance coverage and pharmacy. Without insurance, a prescription for Xiidra can be expensive. Manufacturer discount programs or savings cards may be available to help eligible patients reduce their out-of-pocket costs.
