Rigel Pharmaceuticals Settles Patent Dispute Over TAVALISSE® with Annora Pharma

Resolution of TAVALISSE® Patent Litigation

Rigel Pharmaceuticals, Inc. (Nasdaq: RIGL) has recently announced a significant development in its patent litigation concerning TAVALISSE® (fostamatinib disodium hexahydrate). The company has successfully entered into a settlement agreement with Annora Pharma Private Ltd., Hetero Labs Ltd., and Hetero USA, Inc., collectively referred to as Annora. This agreement resolves ongoing patent disputes related to Rigel's product pertaining to chronic immune thrombocytopenia (ITP).

The genesis of this litigation arose when Annora submitted an Abbreviated New Drug Application (ANDA) to the U.S. Food and Drug Administration (FDA) to market a generic version of TAVALISSE®. This move raised concerns for Rigel regarding its intellectual property rights. However, the settlement now allows Annora to potentially offer this generic alternative in the U.S. market starting in the second quarter of 2032, under certain conditions.

According to Rigel’s President and CEO, Raul Rodriguez, the settlement stands as a testament to the strength of Rigel's intellectual property protections for TAVALISSE. He emphasized the company’s ongoing commitment to advancing its portfolio of innovative therapies tailored to improve the lives of patients dealing with hematological disorders and various forms of cancer.

Understanding Immune Thrombocytopenia (ITP)

To appreciate the importance of TAVALISSE, it is essential to understand ITP, which is a condition where the immune system erroneously attacks and destroys the body’s platelets. These platelets are crucial for blood clotting and healing. Patients suffering from ITP experience symptoms such as excessive bruising and bleeding, and those with chronic ITP may face elevated risks of severe bleeding incidents that can lead to significant health complications or even mortality.

Current treatment options for ITP are somewhat limited. They typically encompass steroids, blood platelet production boosters (thrombopoietin receptor agonists), and splenectomy, but these treatments do not work effectively for all patients. Consequently, many patients are left in need of additional, effective treatment alternatives.

TAVALISSE® has been tailored specifically for adults with chronic ITP who have not experienced adequate responses from prior treatments. The settlement not only aids in fortifying Rigel's market presence but also highlights a critical move towards ensuring broader patient access to this necessary medication.
