On October 2, 2017 Rigel Pharmaceuticals, Inc. (Nasdaq:RIGL) reported that during the company’s mid-cycle meeting with the U.S. Food and Drug Administration (FDA) the FDA indicated that, at this point, it is not planning to hold an Oncology Drugs Advisory Committee (ODAC) meeting to discuss the New Drug Application (NDA) for fostamatinib in patients with chronic or persistent immune thrombocytopenia (ITP) (Press release, Rigel, OCT 2, 2017, View Source [SID1234520747]). Additionally, the FDA indicated that it anticipates meeting the Prescription Drug User Fee Act (PDUFA) action date for the application review, which is April 17, 2018. In an earlier communication, the FDA had conditionally approved the proprietary name TavalisseTM.

“Since we submitted our NDA this spring, we have worked collaboratively with the FDA to answer routine questions as they arise,” said Anne-Marie Duliege, MD, executive vice president and chief medical officer of Rigel. “Our positive interactions with the FDA, including their customary biomedical monitoring (BIMO) inspections at our facilities and clinical sites, are in-line with our expectations and have progressed well. We will continue to work closely with the agency and remain committed to bringing fostamatinib to patients with ITP who are in need of new treatment options.”

About ITP
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. Currently approved therapies for ITP include steroids, blood platelet production boosters (TPO-RAs) and splenectomy. However, not all patients derive a benefit from existing therapies. As a result, there remains a significant medical need for additional treatment options for patients with ITP.
