Business Wire

TOKYO -- December 19, 2012

R-Tech Ueno (JASDAQ:4573):

Sucampo Pharmaceuticals, Inc. (hereinafter referred to as "Sucampo") announced
that it has received approval by the U.S. Food and Drug Administration (FDA)
of the supplemental new drug application (sNDA) to change to Package Insert
(PI) for RESCULA^® ophthalmic solution. (Please refer to Sucampo press release
as of December 12, 2012)

The approved change to the PI will make it possible to prescribe RESCULA^®
ophthalmic solution as a first-line therapeutic agent for open-angle glaucoma
or ocular hypertension, or to concomitantly administer it with other
intraocular pressure (IOP) lowering agents. Open-angle glaucoma is the most
common form of glaucoma. RESCULA^® is a BK (Big Potassium) channel activator,
and is different from other IOP lowering agents. Following this approval,
Sucampo intends to commercialize RESCULA^® ophthalmic solution on the US
market in the first quarter of 2013.

In April 2009 our company granted Sucampo to market RESCULA^® in the U.S. and
Canada for glaucoma or ocular hypertension, and transferred the sales right.
We also licensed their use of related patents, and reached an exclusive
manufacturing & supply agreement with them.

Please note this event does not change our performance projection for the full
financial year that was published on August 9, 2012.

In regard to the news of approval of RESCULA^® sNDA and its commercialization
in the U.S., our President, Yukihiko Mashima, M.D., PhD, has the following to
"I am extremely glad to hear of the U.S. approval of RESCULA^® as a first-line
agent for open-angle glaucoma or ocular hypertension, and the news of its
expected commercial market launch there. In glaucoma patients, many of whom
are aged persons, the Japanese PI for RESCULA^® carries no contraindications
or precautions against these. That is why I think the said drug will become a
valuable therapy agent in the U.S. because it provides the patients to
balanced efficacy of IOP reduction with management of side effects. RESCULA^®
ophthalmic solution has a history of showing notable activities of
neuroprotection from the basic researches, and increase ocular circulation
from the clinical studies. It has proved its high usefulness as an ophthalmic
solution product.
We intend to continue our partnership with the licensee, Sucampo, extend our
market beyond Japan and the U.S. to the global market, and further increase
RESCULA^® ophthalmic solution's standing."
