Tesaro Announces Validation Of Marketing Authorization Application For Oral Rolapitant By European Medicines Agency

WALTHAM, Mass., March 23, 2016 (GLOBE NEWSWIRE) -- TESARO, Inc. (NASDAQ:TSRO), an oncology-focused biopharmaceutical company, today announced that the Marketing Authorisation Application (MAA) for oral rolapitant has been submitted to and validated by the European Medicines Agency. Rolapitant is a substance P/neurokinin-1 (NK-1) receptor antagonist that is marketed by TESARO in the United States under the brand name VARUBI®.

"TESARO is committed to advancing new therapeutic options for patients with cancer, and the oral rolapitant MAA submission represents a significant milestone for the Company," said Mary Lynne Hedley, Ph.D., President and COO of TESARO. "We believe rolapitant could become an important new treatment option for the prevention of nausea and vomiting for patients in Europe who are undergoing emetogenic chemotherapy."

The oral rolapitant MAA is supported by data from four controlled studies covering a spectrum of patients receiving emetogenic chemotherapy. One study enrolled patients receiving moderately emetogenic chemotherapy (MEC), and three studies enrolled patients receiving cisplatin-based highly emetogenic chemotherapy (HEC). The top-line results of each of the three Phase 3 studies of rolapitant were presented in detail at the American Society for Clinical Oncology (ASCO) annual meeting in June 2014. Oral rolapitant was approved by the U.S. Food and Drug Administration on September 1, 2015 and is marketed by TESARO in the United States under the brand name VARUBI®.

"TESARO has an exciting pipeline of oncology therapeutics, and with the filing of our MAA for oral rolapitant today and our planned niraparib MAA filing in the second half of this year, we look forward to globalizing our mission of providing transformative therapies to people bravely facing cancer," said Orlando Oliveira, Senior Vice President and General Manager of TESARO International.

About Chemotherapy-Induced Nausea and Vomiting (CINV)

Chemotherapy-induced nausea and vomiting is a debilitating, yet often preventable, side effect of chemotherapy. More than 50% of patients undergoing highly or moderately emetogenic chemotherapy may experience delayed CINV (25 to 120 hours post chemotherapy)—even when prescribed a 5-HT3 receptor antagonist and corticosteroid.

Blocking both 5-HT3 and NK-1 receptors has been shown to offer better control of nausea and vomiting than inhibiting 5-HT3 receptors alone. Adding a single dose of VARUBI to an antiemetic regimen, including a 5-HT3 receptor antagonist and corticosteroid, further improves prevention of CINV in the delayed phase following chemotherapy.

About VARUBI® (Rolapitant)

VARUBI is a substance P/neurokinin-1 (NK-1) receptor antagonist indicated in combination with other antiemetic agents in adults for the prevention of delayed nausea and vomiting associated with initial and repeat courses of emetogenic cancer chemotherapy, including, but not limited to, highly emetogenic chemotherapy. VARUBI is contraindicated in patients receiving thioridazine, a CYP2D6 substrate. The inhibitory effect of a single dose of VARUBI on CYP2D6 lasts at least seven days and may last longer. Avoid use of pimozide; monitor for adverse events if concomitant use with other CYP2D6 substrates with a narrow therapeutic index cannot be avoided. Please see full prescribing information, including additional important safety information, available at www.varubirx.com.

An intravenous formulation of rolapitant is also being developed. TESARO licensed exclusive rights for the development, manufacture, commercialization, and distribution of VARUBI (rolapitant) from OPKO Health, Inc.
