Sucampo Pharma Europe Receives Validation of Marketing AuthorizationApplications



    Sucampo Pharmaceuticals, Inc. (NASDAQ: SCMP) today announced that its

    wholly-owned European subsidiary, Sucampo Pharma Europe Ltd., received

    notice that all of the Marketing Authorization Applications (MAA) for

    lubiprostone, 24 mcg, (AMITIZA®)

    for the indication of Chronic Idiopathic Constipation in adults have

    been received and validated by the individual regulatory agencies in

    Belgium, Denmark, France, Germany, Ireland, the Netherlands, Spain

    Sweden and the United Kingdom. The applications were submitted using the

    decentralized process with the United Kingdom serving as the reference

    member state. With the validation, the agencies will begin their formal

    review of the applications.
    AMITIZA, developed by Sucampo Pharmaceuticals, is an established therapy

    for Chronic Idiopathic Constipation in adults in the United States.

    AMITIZA, 24 mcg, received U.S. Food and Drug Administration (FDA)

    approval in January 2006 and has been available in the United States for

    Chronic Idiopathic Constipation in adults since April 2006. In April

    2008, AMITIZA® 8 mcg

    was approved by the FDA for Irritable Bowel Syndrome with Constipation

    in adult women 18 years of age and older. It is the only approved

    prescription product for this indication in the United States.
    "The validation of our applications and

    initiation of the review process moves us one step closer to achieving

    our goal of international expansion," said

    Ryuji Ueno, M.D., Ph.D., Ph.D., founder, chairman and chief executive

    officer of Sucampo Pharmaceuticals. "We will

    work closely with these regulatory agencies over the coming months to

    address their questions during the review and approval process."
    These applications represent the first major marketing authorization

    effort for Sucampo Pharmaceuticals outside the United States. Sucampo

    Pharmaceuticals continues to review marketing opportunities in other

    parts of the world in order to build upon the current success of AMITIZA® in the United States.
    About AMITIZA® (lubiprostone)
    AMITIZA® (lubiprostone) is indicated for the treatment of Chronic Idiopathic

    Constipation (24 mcg) in adults and for Irritable Bowel Syndrome with

    Constipation (8 mcg) in women 18 years of age and older.
    AMITIZA is contraindicated in patients with known or suspected

    mechanical gastrointestinal obstruction. Patients with symptoms

    suggestive of mechanical gastrointestinal obstruction should be

    thoroughly evaluated by the treating physician to confirm the absence of

    such an obstruction prior to initiating AMITIZA treatment.
    The safety of AMITIZA in pregnancy has not been evaluated in humans.

    AMITIZA should be used during pregnancy only if the benefit justifies

    the potential risk to the fetus. Women who could become pregnant should

    have a negative pregnancy test prior to beginning therapy with AMITIZA

    and should be capable of complying with effective contraceptive measures.
    Patients taking AMITIZA may experience nausea. If this occurs

    concomitant administration of food with AMITIZA may reduce symptoms of

    nausea. Patients who experience severe nausea should inform their

    physician.
    AMITIZA should not be prescribed to patients that have severe diarrhea.

    Patients should be aware of the possible occurrence of diarrhea during

    treatment and inform their physician if the diarrhea becomes severe.
    Patients taking AMITIZA may experience dyspnea within an hour of first

    dose. This symptom generally resolves within three hours, but may recur

    with repeat dosing. Patients who experience dyspnea should inform their

    physician.
    In clinical trials of AMITIZA (24 mcg) in patients with Chronic

    Idiopathic Constipation, the most common adverse reactions (incidence >

    4%) were nausea (29%), diarrhea (12%), headache (11%), abdominal pain

    (8%), abdominal distention (6%), and flatulence (6%).
    In clinical trials of AMITIZA (8 mcg) in patients with Irritable Bowel

    Syndrome with Constipation, the most common adverse reactions (incidence

    > 4%) were nausea (8%), diarrhea (7%), and abdominal pain (5%).
