Shionogi Inc. – Why Work For Us?

About Shionogi Inc.

Shionogi Inc. is the U.S. subsidiary of Shionogi & Co., Ltd., a 140-year-old global pharmaceutical company with headquarters in Osaka, Japan. In the U.S., Shionogi Inc. leverages our science-based heritage to develop and commercialize pharmaceutical products to treat unmet medical needs in our core areas of infectious diseases and pain, as well as other areas of high medical need, including chronic liver disease.

It’s Time to Revolutionize Medicine Again

More than 23,000 men, women and children in the U.S. die every year from antibiotic-resistant infections1 while over 4,000 Americans perish from influenza.2 In addition, over 100 million suffer from chronic pain3 and 3.9 million adults in the U.S. are diagnosed with liver disease.4 Shionogi’s mission is to supply the best possible medicines to protect the health and well-being of the patients we serve.

With over 50 years of anti-infective research experience, Shionogi has helped to revolutionize the development of antibacterial and antiviral treatments. As bacteria, pathogens and other viruses adapt to resist existing treatments—causing millions of untreatable infections around the world—Shionogi is pursuing the development of novel treatments to combat this evolving threat.

Shionogi, both itself and through innovative alliances, is also pursuing the development of new treatments in other areas of high medical need, including inflammatory pain, neuropathic pain, Alzheimer’s disease and ADHD.

At Shionogi Inc., we’re intensely focused on developing and commercializing the scientific breakthroughs emerging from our research laboratories in Japan as well as discoveries of our strategic alliance partners. We couple our innovative discovery base with capabilities to advance drug candidates rapidly from lab to clinic to patient, forming, where appropriate, bold new partnerships to accelerate and amplify the availability of these new medications to patients around the world.

Our History

In 1878, Gisaburo Shiono, Sr. founded the company that became Shionogi & Co., Ltd. Still located on the original site in Osaka, Japan, today’s Shionogi retains its entrepreneurial spirit while having the resources of a fully integrated pharmaceutical company serving patients worldwide.

140 Years of Entrepreneurship

Our research scientists have discovered therapeutics including naldemedine, rosuvastatin and dolutegravir, and are currently working on many more potential future products.

In 2008, Shionogi acquired Sciele Pharma, Inc., a specialty pharmaceutical company based in Atlanta, Georgia, and in 2011, merged it with Shionogi’s small existing development organization in New Jersey. The resulting company became Shionogi Inc., which has the mandate to bring Shionogi innovation to U.S. patients. In 2017, Shionogi Inc. gained approval of Symproic®, the first medicine both discovered and globally developed by Shionogi.

Shionogi Inc. now has a development organization capable of conducting multiple simultaneous late-stage clinical programs and submitting new drug application (NDA) filings worldwide, and we are now establishing the commercial capabilities to effectively bring these medicines to the appropriate patients.

Shionogi Leadership Team

Focused on Solutions

The Shionogi Inc. leadership team has decades of combined pharmaceutical and industry experience in developing and commercializing therapeutics. Since 2011, when Shionogi Inc. was established in the U.S., our leadership team has focused on bringing the benefits of Shionogi's small molecule drug innovations to U.S. patients through our own efforts and through multiple inventive collaborations. During this period, Shionogi Inc. gained our first two New Chemical Entity (NCE) approvals while reshaping our business around our science-based heritage and core areas of infectious diseases and pain.
