News Releases

Taiho Pharmaceutical Co., Ltd. (hereinafter “Taiho”) announced today that it has submitted to the Japanese Ministry of Health, Labour and Welfare a new drug application for an NK₁ receptor antagonist antiemetic drug (development code: Pro-NETU; generic name: fosnetupitant chloride hydrochloride; hereinafter “fosnetupitant”) for gastrointestinal symptoms (nausea and vomiting) associated with cancer chemotherapy.

Fosnetupitant is an NK₁ receptor antagonist antiemetic drug developed for the prevention of chemotherapy-induced nausea and vomiting. It is a phosphorylated pro-drug preparation (injection) of netupitant, the active component. The prevention of chemotherapy-induced nausea and vomiting is considered important in clinical practice. Taiho acquired exclusive development and marketing rights for fosnetupitant in Japan under a license agreement signed in April 2011 with Helsinn Healthcare SA and has conducted clinical trials in Japan since then.

The new drug application is based on the results of a Phase III clinical trial comparing the efficacy and safety of fosnetupitant and fosaprepitant (NK₁ receptor antagonist) in patients receiving highly emetogenic chemotherapy. In the trial, either fosnetupitant (235 mg) or fosaprepitant (150 mg) was administered in a single I.V. dose prior to administration of the chemotherapeutic agent, in combination with palonosetron (5-HT₃ receptor antagonist) and dexamethasone. Details of the trial results will be presented at a future medical conference.

Within Taiho’s mainstay field of oncology, the company is also focusing on cancer supportive care. Under a former distribution and license agreement effective as of January 2004 with Helsinn Healthcare SA, Taiho has been marketing the 5-HT₃ receptor antagonist Aloxi^® (generic name: palonosetron hydrochloride) in Japan since April 2010.

Taiho will work to secure approval of fosnetupitant, aiming to deliver the agent as soon as possible as a new treatment which can contribute to improving quality of life for patients, thereby contributing to comprehensive care in cancer.

Taiho Pharmaceutical, a subsidiary of Otsuka Holdings Co., Ltd., is an R&D-driven specialty pharma company with a focus on oncology. Taiho Pharmaceutical also has development programs in allergy and immunology, urology and consumer healthcare products. Our corporate philosophy is simple: “We strive to improve human health and contribute to a society enriched by smiles.”
