Rigel Announces Tavalisse(TM) as Proprietary Name for Fostamatinib in the United StatesSOUTH SAN FRANCISCO, Calif., April 27, 2017 -- (Healthcare Sales & Marketing Network) -- Rigel Pharmaceuticals, Inc. (Nasdaq: RIGL) today announced that the U.S. Food and Drug Administration (FDA) has conditionally accepted the proprietary name Tavalisse™ for the company's investigational product candidate, fostamatinib disodium, an oral spleen tyrosine kinase (SYK) inhibitor. In addition, Rigel has applied to the U.S. Patent and Trademark Office to obtain federal registration of the Tavalisse mark.
The name Tavalisse (pronounced - ta vah lees') was developed based on the FDA's Guidance for Industry, Contents of a Complete Submission for the Evaluation of Proprietary Names. Created with the help of experts in this field, the proprietary name development included input from prescribers, pharmacists, linguists and employees to create a unique and approachable name.
Earlier this month, the company announced that it submitted a New Drug Application (NDA) to the FDA for Tavalisse in patients with chronic and persistent immune thrombocytopenia (ITP). The FDA previously granted Orphan Drug designation to Tavalisse for the treatment of patients with ITP.
The NDA is supported by data from the Phase 3 clinical program for Tavalisse in ITP, which was comprised of three studies, two randomized placebo-controlled studies (Studies 047 and 048) and an open-label extension study (Study 049). In total, 163 ITP patients have been treated with Tavalisse and included in the NDA submission. Across all indications, Tavalisse has been evaluated in over 4,600 subjects.
In patients with ITP, the immune system attacks and destroys the body's own blood platelets, which play an active role in blood clotting and healing. Common symptoms of ITP are excessive bruising and bleeding. People suffering with chronic ITP may live with increased risk of severe bleeding events that can result in serious medical complication, or even death. Current therapies for ITP include steroids, blood platelet production boosters (TPOs) and splenectomy. However, a portion of patients do not derive a benefit from existing therapies. As a result, there remains a significant medical need for additional treatment options for patients with ITP.
Tavalisse is an oral investigational drug candidate with a unique mechanism of action designed to inhibit SYK kinase, a key player in the immune process that leads to platelet destruction in ITP. Unlike other therapies that modulate the immune system in different ways or stimulate platelet production, Tavalisse may address the underlying autoimmune cause of ITP by impeding platelet destruction.
