Santen Announces U.S. FDA Filing Acceptance Of New Drug Application (NDA) For Intravitreal Sirolimus (DE-109) In The Treatment Of Non-Infectious Uveitis Of The Posterior Segment

OSAKA, Japan--(BUSINESS WIRE)--Santen Pharmaceutical Co., Ltd. (hereinafter, “Santen”), a specialized ophthalmology company headquartered in Osaka, Japan, today announced that the U.S. Food and Drug Administration (FDA) has accepted for review the New Drug Application (NDA) for intravitreal (IVT) sirolimus (440 µg), development code DE-109, for the treatment of non-infectious uveitis of the posterior segment (NIU-PS). The FDA has set an action date of December 24, 2017 to complete its review of the IVT sirolimus NDA, per the Prescription Drug User Fee Act (PDUFA). IVT sirolimus was granted orphan drug designation by the FDA and the European Commission (EC) in 2011.

IVT sirolimus, an mTOR inhibitor, is an investigational first-in-class targeted, immunoregulator being developed by Santen for the treatment of patients with NIU-PS. NIU-PS is a progressive and chronic inflammatory disease of the eye that can lead to vision impairment and blindness. The NDA for IVT sirolimus is supported by data from the SAKURA Program, the largest Phase III global clinical program to date evaluating patients with NIU-PS.

“The FDA acceptance of the NDA for IVT sirolimus is an important milestone, and brings us closer to potentially offering a locally-administered treatment option for patients with NIU-PS,” said Naveed Shams, M.D. Ph.D, Chief Scientific Officer and Head of Global R&D at Santen.

About IVT Sirolimus
IVT sirolimus (440 µg), an mTOR inhibitor, is a first-in-class targeted immunoregulator being developed for the treatment of NIU-PS – a progressive and chronic inflammatory disease of the eye. IVT sirolimus inhibits the protein kinase, mTOR, which plays a key role in inflammation. The result is immunoregulation by: interrupting the inflammatory cascade through the inhibition of T-cell activation, differentiation and proliferation; and, promoting immune tolerance, increasing regulatory T lymphocytes (Tregs).

About Uveitis
Uveitis is a leading cause of preventable blindness in working-age adults and is estimated to account for 10 to 15 percent of cases of total blindness in the developed world.1 It is characterized by intraocular inflammation that is often chronic, can flare up at any time and can lead to visual impairment and vision loss. NIU-PS includes intermediate, posterior and panuveitis.
