Item 8.01.  Other Events.

On September 25, 2012, Sucampo Pharmaceuticals, Inc. ("Sucampo") and Takeda Pharmaceuticals U.S.A., Inc. today announced that the U.S. Food and Drug Administration (FDA) has granted priority review status to their filing of a supplemental new drug application (sNDA).

The sNDA was filed in late July seeking approval for an additional indication for AMITIZA^® (lubiprostone) for the treatment of opioid-induced constipation (OIC) in patients with chronic, non-cancer pain.

The FDA’s priority review, which allows for an abbreviated review period of six months, is granted to drugs that offer either significant advances in treatment or provide a treatment where there is no existing adequate therapy. As a result of this priority review, Sucampo and Takeda expect the FDA’s decision by late January 2013.  

“One of the most common adverse reactions of opioid medications is opioid-induced constipation, a medical condition for which there are currently no approved oral prescription treatment options available,” said Dr. Ryuji Ueno, M.D., Ph.D., Ph.D., Chairman, Chief Scientific Officer, and Chief Executive Officer of Sucampo.  “The priority review of this sNDA application underscores that the management of OIC is an unmet need of patients with chronic pain and highlights the need for new therapies to address this condition.”

The information in this Item 8.01 and Exhibit 99.1 to this Form 8-K shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934 (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such a filing.

(TPUSA) today announced that the U.S. Food and Drug Administration (FDA) has granted priority review of their supplemental new drug application (sNDA) filing.

About AMITIZA

AMITIZA (lubiprostone) is a chloride channel activator indicated for the treatment of chronic idiopathic constipation (CIC) (24 mcg twice daily) in adults and for irritable bowel syndrome with constipation (8 mcg twice daily) in women 18 years of age and older by the FDA in the United States. AMITIZA (lubiprostone) is approved in Japan for the treatment of chronic constipation (excluding constipation caused by organic diseases); in Switzerland for CIC; and in the United Kingdom for CIC.

Important Safety Information

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 healthcare provider 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 healthcare provider.

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 healthcare provider 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 healthcare provider. Some patients have discontinued therapy because of dyspnea.

In clinical trials of AMITIZA (24 mcg twice daily vs. placebo; N=1113 vs. N=316) in patients with Chronic Idiopathic Constipation (CIC), the most common adverse reactions (incidence > 4%) were nausea (29% vs. 3%), diarrhea (12% vs. <1%), headache (11% vs. 5%), abdominal pain (8% vs. 3%), abdominal distension (6% vs. 2%), and flatulence (6% vs. 2%).

In clinical trials of AMITIZA (8 mcg twice daily vs. placebo; N=1011 vs. N=435) in patients with Irritable Bowel Syndrome with Constipation (IBS-C), the most common adverse reactions (incidence > 4%) were nausea (8% vs. 4%), diarrhea (7% vs. 4%), and abdominal pain (5% vs. 5%).

Reduce the dosage in CIC patients with moderate and severe hepatic impairment. Reduce the dosage in IBS-C patients with severe hepatic impairment.
