Cyclosporine Eye Drops 0.09%

Eye Drops 0.09% is a novel, twice-a-day, preservative-free,
clear ophthalmic solution using a globally patented nanotechnology. The product
uses a unique, first-in-class vehicle in which the cyclosporine molecules are
surrounded by tiny structures called “micelles”. This micelle encapsulation improves
tissue penetration and safety. Currently, the product has been approved for
marketing in the U.S. under the brand name of CequaTM for increasing
tear production in patients with dry eye, and also been approved for
commercialization in Australia.

China, the incidence of dry eye is 21%-30%, of which moderate-to-severe
patients are about 118-168 million. Although various symptom alleviating agents
such as artificial tears are available in the market, there are few
satisfactory options in practice. In addition, in terms of ophthalmic
cyclosporine, related treatment options are still limited due to the historic
challenge of making an optic formulation of this agent at a relatively higher concentration
without increasing side effects. Once approved in China, the product is
expected to meet the clinical needs of patients with dry eye, providing them a safe
and effective treatment option.
