Santen’s Verkazia® (Cyclosporine Ophthalmic Emulsion) 0.1% Now Available for the Treatment of Vernal Keratoconjunctivitis in Children and Adults in the United States

May 2, 2022 11:05 UTC

EMERYVILLE, Calif.--(BUSINESS WIRE)-- Santen, Inc., the U.S. subsidiary of Santen Pharmaceutical Co., Ltd. (hereinafter, Santen), a global company focused exclusively on eye care, today announced that Verkazia® (cyclosporine ophthalmic emulsion) 0.1% is now available in the United States for the treatment of vernal keratoconjunctivitis (VKC), a rare and recurrent allergic eye condition that causes severe inflammation of the surface of the eye. Verkazia – which is administered as an eye drop – is the first and only FDA-approved topical immunomodulator (drug that suppresses the immune system) for the treatment of VKC in children and adults.

“We are proud to make Verkazia available for all those with VKC in the United States who have lacked optimal treatment options for this condition. VKC can often disrupt everyday activities due to the debilitating symptoms including eye itching, tearing, pain, light sensitivity and even blurred vision,” said Shigeo Taniuchi, President and CEO of Santen. “This is also a monumental milestone for Santen as we deliver an innovative solution that we have brought from the development stage to commercialization within the U.S. market – the largest ophthalmology market in the world. In addition, having a treatment option for the rare disease VKC will strengthen our existing product portfolio for ocular surface disease in the United States. This is the first step for us to address the unmet needs of VKC patients, by helping those who have been struggling with symptoms to resume their daily lives.”

Verkazia is a prescription-only, uniquely formulated cationic nanoemulsion that provides improved ocular bioavailability of cyclosporine, which has been shown to be effective in the management of VKC.1 Verkazia is thought to act by blocking the release of pro-inflammatory cytokines – such as IL-2 – that can cause the chronic, severe, potentially debilitating allergic inflammation of the ocular surface seen in patients affected by VKC.2,3

“The symptoms associated with VKC, such as itching and eye pain, can affect quality of life and prevent those affected from participating in normal daily activities like school or sports. And if left untreated, severe cases of VKC can even lead to vision loss,” said Dr. Sherif El-Harazi, ophthalmologist, Medical Director and Founder of Lugene Eye Institute and Global Research Management in Glendale, California. “The availability of this proven treatment will be an important new tool to help patients with VKC get back to living their lives.”

About Verkazia

Worldwide, Verkazia is available for the treatment of VKC in the United States, Canada, and select countries across Asia and Europe. In several countries, it has been designated as an orphan drug.

The FDA approved Verkazia in June 2021 based on data from two randomized, multi-center, double-masked, vehicle-controlled, clinical trials (VEKTIS Study and NOVATIVE Study). In the studies, Verkazia demonstrated improvements in inflammation of the cornea (keratitis score) and ocular itching. The most common adverse reactions reported in greater than 5 percent of patients were eye pain (12%) and eye pruritus (8%), which were usually transitory and occurred during instillation.

Verkazia is an important addition to the commercial products Santen has offered since the acquisition of Eyevance Pharmaceuticals in late 2020.
