Sucampo Reports Second Quarter 2014 Financial Results and Corporate Update

Positive Net Income Driven by Strong Revenue Growth in Product Royalty and Product Sales

CEO Peter Greenleaf to Discuss Results of Sucampo's Strategic Review

Company Raises Full Year 2014 Earnings Guidance

Company to host conference call today at 8:30 am Eastern

BETHESDA, Md., Aug. 5, 2014 (GLOBE NEWSWIRE) -- Sucampo Pharmaceuticals, Inc. (Sucampo) (Nasdaq:SCMP) today reported consolidated financial results for the second quarter and six months ended June 30, 2014. Sucampo reported year over year growth of 16% to $13.9 million in product royalty revenue and 122% to $7.5 million in product sales, net income of $1.6 million and fully-diluted earnings per share of $0.04 during the second quarter of 2014.

"In the second quarter, Sucampo continued to make excellent progress driven by our strong financial performance. AMITIZA royalty revenue in the U.S. and product sales revenue in Japan grew impressively, and in Europe we made important strides in increasing access to AMITIZA for the U.K. and Swiss markets. In addition, we continued to make significant progress against our 2014 objectives as well as in planning for Sucampo's continued evolution, advancing our clinical development programs, focusing our resources on value-enhancing activities, and strengthening our management team," said Peter Greenleaf, Chief Executive Officer of Sucampo. "During this morning's call, I look forward to sharing the results of our strategic review and my views of how we will focus Sucampo on our core capabilities of scientific innovation to accelerate patient, healthcare provider, and shareholder value."

Second Quarter 2014 Operational Review

AMITIZA

• In the United States (U.S.), AMITIZA^® (lubiprostone) total prescriptions were 327,941, an increase of 4.3%, compared to the second quarter of 2013. Net sales of AMITIZA, reported by Takeda Pharmaceuticals U.S.A., Inc. (Takeda) for royalty calculation purposes, increased 16% to $77.0 million for the second quarter of 2014, compared to $66.7 million in the same period of 2013. Net sales of AMITIZA, reported by Takeda for royalty calculation purposes, increased 16% to $152.0 million for the first six months of 2014, compared to $131.5 million in the same period of 2013.
   
• In Japan, Sucampo's revenue from sales of AMITIZA to Abbott for the second quarter of 2014 was $7.2 million, an increase of $3.9 million compared to the same period of 2013. Sucampo's revenue from sales of AMITIZA to Abbott for the first six months of 2014 was $13.3 million, an increase of $7.8 million compared to the same period of 2013.
   
• In Switzerland, Swissmedic, the Swiss Agency for Therapeutic Products, approved AMITIZA for the treatment of opioid-induced constipation (OIC) in chronic, non-cancer adult patients. This is the second indication for AMITIZA in Switzerland, where it is also approved for the treatment of chronic idiopathic constipation (CIC).
   
• In the United Kingdom (U.K.), the National Institute for Health and Care Excellence released the technology appraisal guidance for the recommendation of the use of AMITIZA in the treatment of CIC and associated symptoms in adults who have failed laxatives. Sucampo continued to make progress in planning for approval through the Mutual Recognition Procedure (MRP) in an additional 29 European Union countries for AMITIZA for CIC. We anticipate that the MRP will commence during the third quarter of 2014.

RESCULA

• On July 15, 2014, Sucampo received an approval letter from the U.S. Food and Drug Administration (FDA) to its prior approval supplement in response to FDA's review of the revised drug master file of R-Tech Ueno, Ltd. The approval letter provides for the addition of Nitto Medic in Japan as a new production site for RESCULA^® (unoprostone isopropyl ophthalmic solution) 0.15%.

Research and Development

• Obtained results from a phase 1b trial evaluating the safety and pharmacokinetics of an orally-administered ion channel activator, which was found to be generally well-tolerated. This compound is in clinical development for lumbar spinal stenosis (LSS), a degenerative disease of the lumbar spine.

Corporate

• Peter Lichtlen, M.D., Ph.D., was appointed Chief Medical Officer.
   
• Max Donley was appointed Executive Vice President of Human Resources.

Second Quarter 2014 Financial Review

• Net income was $1.6 million, or $0.04 per diluted share, for the second quarter of 2014 compared to a net income of $6.2 million, or $0.15 per diluted share, in the same period in 2013. Net income was $2.4 million, or $0.05 per diluted share, for the first six months of 2014 compared to a net income of $3.2 million, or $0.07 per diluted share, in the same period in 2013. The decrease for both periods was driven by the receipt in 2013 of a $10.0 million milestone payment from Takeda upon the first commercial sale of AMITIZA for OIC.
   
• Total revenues were $24.1 million for the second quarter of 2014 compared to $27.0 million in the same period in 2013, a decrease of 11%. Total revenues were $46.2 million for the first six months of 2014 compared to $43.9 million in the same period in 2013, an increase of 5%. The decrease for the second quarter 2014 was primarily due to the 2013 receipt of the $10.0 million milestone payment from Takeda upon the first commercial sale of AMITIZA for OIC. The increase for the first six months of 2014 was primarily due to the higher royalty revenue on AMITIZA net sales in the U.S. and the growth of AMITIZA sales in Japan partially offset by lower R&D revenue as a result of the OIC milestone received in the prior year period.
   
• Costs of goods sold were $3.8 million for the second quarter of 2014 compared to $1.9 million for the same period of 2013. Costs of goods sold were $7.2 million for the first six months of 2014 compared to $3.2 million for the same period of 2013. The increase was primarily due to greater volume of AMITIZA sales in Japan.
   
• R&D expenses were $4.3 million for the second quarter of 2014 compared to $4.4 million for the same period of 2013, a decrease of 4%. R&D expenses were $9.4 million for the first six months of 2014 compared to $10.1 million for the same period of 2013, a decrease of 7%. The decrease for both periods was primarily due to the lower costs associated with our LSS trials, partially offset by increased costs of our lubiprostone pediatric trial.
   
• G&A expenses were $8.2 million for the second quarter of 2014 compared to $6.0 million for the same period of 2013, an increase of 37%. G&A expenses were $15.5 million for the first six months of 2014 compared to $13.2 million for the same period of 2013, an increase of 17%. The increase for both periods was primarily due to legal fees from prosecuting our patent infringement lawsuit filed in February 2013.
   
• Selling & Marketing expenses were $4.0 million for the second quarter of 2014 compared to $4.6 million for the same period of 2013, a decrease of 12%. Selling & Marketing expenses were $7.7 million for the first six months of 2014 compared to $9.9 million for the same period of 2013, a decrease of 23%. The decrease for both periods was primarily due to the replacement of our in-house sales force in 2013 with a lower-cost contract sales force in 2014 and lower samples expense for RESCULA.

Cash, Cash Equivalents, Restricted Cash and Marketable Securities

At June 30, 2014, cash, cash equivalents, restricted cash and investments were $103.6 million compared to $95.9 million at December 31, 2013.

Guidance

Sucampo today increased its earnings guidance for 2014. Sucampo now expects full year 2014 GAAP net income to be in the range of $4.0 million to $6.0 million, or $0.08 to $0.13 per diluted share.
