1. Business Organization and Basis of Presentation

Description of the Business

Sucampo Pharmaceuticals, Inc. (the Company) is a global biopharmaceutical company focused on the development and commercialization of medicines that meet major unmet medical needs of patients worldwide.

The Company is currently focused on developing compounds known as prostones, which are ion channel activators, to treat gastrointestinal and oncology-based inflammatory disorders.

The Company currently generates revenue primarily from product royalties, development milestone payments, product sales and reimbursements for clinical development activities. The Company expects to continue to incur significant expenses for the next several years as the Company continues its research and development activities, seeks regulatory approvals and additional indications for approved products and other compounds and seeks strategic opportunities for in-licensing non-prostone clinical candidates.

In the United States (U.S.), AMITIZA^® (lubiprostone) is marketed for three gastrointestinal indications under the collaboration and license agreement (as amended in October 2014, the North America Takeda Agreement) with Takeda Pharmaceutical Company Limited (Takeda). These indications are chronic idiopathic constipation (CIC) in adults, irritable bowel syndrome with constipation (IBS-C) in adult women and opioid-induced constipation (OIC) in adults suffering from chronic non-cancer related pain. Under the North America Takeda Agreement, the Company is primarily responsible for clinical development activities while Takeda is responsible for commercialization of AMITIZA in the U.S. and Canada. In Canada, the Company has filed a New Drug Submission (NDS) for AMITIZA for the CIC and OIC indications and anticipates a decision in the second half of 2015. In October 2014, the Company and Takeda executed amendments (Takeda Amendment) to the North America Takeda Agreement which, among other things, extended the term of the North America Takeda Agreement beyond December 2020. During the extended term, Takeda and the Company will split the annual net sales revenue of the branded AMITIZA products. In addition, the North America Takeda Agreement was amended to terminate the Company’s right to perform commercialization activities with respect to AMITIZA and Takeda’s obligation to reimburse the Company for such commercialization activities.

In Japan, AMITIZA is marketed under a license, commercialization and supply agreement (the Japan Mylan Agreement) that was transferred to Mylan, Inc. (Mylan) from Abbott Laboratories, Inc. (Abbott), as of February 27, 2015, as part of Mylan’s acquisition of a product portfolio from Abbott. Mylan markets AMITIZA in Japan for chronic constipation (CC) excluding constipation caused by organic diseases. AMITIZA is Japan’s only prescription medicine for CC. The Company did not experience any significant changes in the commercialization of AMITIZA in Japan as a result of the transfer of the Japan Mylan Agreement from Abbott to Mylan.

In the People’s Republic of China, the Company entered into an exclusive license, development, commercialization and supply agreement (the China Gloria Agreement) with Harbin Gloria Pharmaceuticals Co., Ltd. (Gloria), for AMITIZA in May 2015. Gloria is responsible for all development activities and costs, as well as commercialization and regulatory activities, for AMITIZA in the People’s Republic of China. The Company will be the exclusive supplier of AMITIZA to Gloria at an agreed upon supply price and will be eligible for an additional milestone payment upon the occurrence of a regulatory or, alternatively, a commercial milestone event. As a result of this agreement, the Company recognized a payment of $1.0 million from Gloria, which is the first tranche of the $1.5 million upfront payment agreed to as part of the China Gloria Agreement. In June 2015, the China Food and Drug Administration (CFDA) accepted an Investigational New Drug (IND) application for a pivotal study of AMITIZA in patients with CIC. As a result of this acceptance, the Company recognized a payment of $500,000 from Gloria, which is the second tranche of the $1.5 million upfront payment.

In October 2014, the Company entered into an exclusive license, development, commercialization and supply agreement (the Global Takeda License Agreement) for lubiprostone with Takeda, through which Takeda has the exclusive rights to further develop and commercialize AMITIZA in all global markets, except the U.S., Canada, Japan and the People’s Republic of China. In addition, Takeda will become the marketing authorization holder and will be responsible for all commercialization and regulatory activities in the areas covered by the Global License Agreement. In the United Kingdom (U.K.), the Company made AMITIZA available for CIC and in Switzerland, Takeda markets AMITIZA for CIC and OIC. The Company filed for the OIC indication in the U.K., but in March 2014 the Company received notification from the Medicines and Healthcare Products Regulatory Agency (MHRA) that the application for the OIC indication was not approved and the Company subsequently resubmitted the application for OIC for re-review to MHRA. The Company currently awaits MHRA’s decision on the OIC indication. In January 2015, the Company successfully completed the European mutual recognition procedure for AMITIZA for the treatment of CIC in select European countries, resulting in a recommendation for marketing authorization. As a result of that recommendation, Ireland, Belgium, the Netherlands, Luxembourg, Austria, Germany and Italy have approved AMITIZA for CIC, and the Company anticipates receiving approval by Spain in the second half of 2015.

The Company’s clinical development programs include the following:

Lubiprostone Alternate Formulation

The Company is developing an alternate formulation of lubiprostone, both for adult and pediatric patients who are unable to take capsules and for naso-gastric tube fed patients. Takeda is funding 100% of the costs of this alternate formulation work and the Company expects to initiate a phase 3 trial of the alternate formulation of lubiprostone in adults in the second half of 2015.

Lubiprostone for Pediatric Functional Constipation

The phase 3 program required to support an application for marketing approval of lubiprostone for pediatric functional constipation comprises four clinical trials, two of which are currently ongoing and are both testing the soft gelatin capsule formulation of lubiprostone in patients 6 to 17 years of age. The first of the two trials is a pivotal 12-week, randomized, placebo-controlled trial which was initiated in December 2013. The second trial is a follow-on, long-term safety extension study which was initiated in March 2014. The Company is also evaluating the timing of the initiation of the additional two trials in its phase 3 program for pediatric functional constipation, which will be in children aged 6 months to less than 6 years and will require the alternate formulation of lubiprostone as described above.

Cobiprostone for Oral Mucositis (OM)

In the first quarter of 2014, the Company completed its phase 1b trial that evaluated the safety and pharmacokinetics of an orally applied liquid formulation of cobiprostone. In this phase 1b trial, cobiprostone was well-tolerated overall and revealed low systemic exposure. In May 2015, the FDA granted Fast Track Designation for cobiprostone for the prevention of OM. The FDA has also accepted the Company’s IND application to initiate a phase 2 clinical trial of cobiprostone for the prevention of OM in patients suffering with head and neck cancer receiving concurrent radiation and chemotherapy. The Company plans to initiate a phase 2a study in the second half of 2015. The Company had also filed for orphan drug designation in the European Union (E.U.) but in April 2015 withdrew the application as the target population was estimated to be too large for orphan drug status.

Cobiprostone for Non-Erosive Reflux Disease (NERD)/Gastroesophageal Reflux Disease (GERD)

In December of 2014, the Company initiated a phase 2a program for cobiprostone in NERD/GERD in patients who have had a non-satisfactory response to proton pump inhibitors. The study, conducted in Japan, is currently ongoing.

Unoprostone Isopropyl

In March 2015, the Company announced that it would return all licenses for unoprostone isopropyl to R-Tech Ueno, Ltd (R-Tech). These licenses had provided the Company with exclusive development and commercialization rights to unoprostone isopropyl globally except for Japan, the People’s Republic of China, Taiwan and Korea, and covered certain indications including the lowering of intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension, retinitis pigmentosa and geographic atrophy. Effective May 6, 2015, the Company and R-Tech executed a transfer and termination agreement to effectuate the return of the licenses as well as regulatory, commercial and pharmacovigilance information. As a result of this transfer and termination agreement, the Company received a payment of $2.6 million from R-Tech, consisting of $2.0 million for the transfer and assignment of certain rights and assets, and $0.6 million as a reimbursement of an FDA fee.

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles in the United States of America (GAAP) and the rules and regulations of the U.S. Securities and Exchange Commission (SEC) for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the Company’s Consolidated Financial Statements as of and for the year ended December 31, 2014 included in the Company’s Annual Report on Form 10-K, which was filed with the SEC on March 9, 2015. The financial information as of June 30, 2015, the three and six months ended June 30, 2015, and the three and six months ended June 30, 2014 is unaudited. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. In the opinion of the Company’s management, all adjustments, consisting only of normal recurring adjustments or accruals, considered necessary for a fair statement of the results of these interim periods have been included. The results of the Company’s operations for any interim period are not necessarily indicative of the results that may be expected for any other interim period or for a full fiscal year.

The Condensed Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries: Sucampo AG (SAG) based in Zug, Switzerland, through which the Company conducts certain of its worldwide and European operations; Sucampo Pharma, LLC (SPL) based in Osaka, Japan, through which the Company conducts its Asian operations; Sucampo Pharma Americas LLC, (SPA) based in Bethesda, Maryland, through which the Company conducts its North American operations; and Sucampo Pharma Europe, Ltd., (SPE) based in Oxford, United Kingdom. All significant inter-company balances and transactions have been eliminated.

The preparation of financial statements in conformity with GAAP requires management to make estimates that affect the reported amounts of assets and liabilities at the date of the financial statements, disclosure of contingent assets and liabilities, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

2. Summary of Significant Accounting Policies

Certain Risks, Concentrations and Uncertainties

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist of cash and cash equivalents, restricted cash, investments and receivables. The Company places its cash, cash equivalents and restricted cash with highly rated financial institutions and invests its excess cash in highly rated investments. As of June 30, 2015 and December 31, 2014, approximately $32.5 million, or 25.4%, and $37.0 million, or 33.6%, respectively, of the Company’s cash, cash equivalents, restricted cash and investments were issued or insured by the U.S. government or U.S. government agencies. The Company has not experienced any losses on these accounts related to amounts in excess of insured limits.

Revenues from Takeda, an unrelated party, accounted for 53.6% and 68.1% of the Company’s total revenues for the three months ended June 30, 2015 and 2014, respectively, and 57.4% and 69.6% for the six months ended June 30, 2015 and 2014, respectively.

Revenues from Mylan (formerly Abbott), an unrelated party, accounted for 41.6% and 30.0% of the Company’s total revenues for the three months ended June 30, 2015 and 2014, respectively, and 39.8% and 28.8% for the six months ended June 30, 2015 and 2014, respectively.

Accounts receivable, unbilled accounts receivable and product royalties receivable from Takeda accounted for 73.7% and 88.5% of the Company’s total accounts receivable, unbilled accounts receivable and product royalties receivable at June 30, 2015 and December 31, 2014, respectively.

The Company depends significantly upon collaborations with Takeda and Mylan, and its revenues may be impacted if these relationships are disrupted.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued authoritative guidance which sets forth a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. The guidance is effective for annual reporting periods, including interim reporting periods within those periods, beginning after December 15, 2016, and early adoption is not permitted. Companies may use either a full retrospective or a modified retrospective approach to adopt this guidance. The Company is currently evaluating the impact of this guidance.

On July 9, 2015, the FASB voted to defer the effective date of the above mentioned revenue recognition guidance by one year to December 15, 2017 for interim and annual reporting periods beginning after that date and permitted early adoption of the standard, but not before the original effective date of December 15, 2016

Earnings Per Share [Abstract]

Earnings Per Share [Text Block]

3. Net Income per Share

Basic net income per share is computed by dividing net income by the sum of the weighted average class A common shares outstanding. Diluted net income per share is computed by dividing net income by the weighted average common shares and potential dilutive common shares outstanding. Diluted net loss per share, when applicable, is computed by dividing net loss by the weighted average common shares outstanding without the impact of potential dilutive common shares outstanding because they would have an anti-dilutive impact on diluted net loss per share.

The computation of net income per share for the three and six months ended June 30, 2015 and 2014 is shown below:

	Three Months Ended June 30,				Six Months Ended June 30,

The Company performs fair value measurements in accordance with the Financial Accounting Standards Board’s guidance for fair value measurements and disclosures, which defines fair value as the exchange price that would be received for selling an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. A fair value hierarchy is established which requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The Company classifies its investments into the following categories based on the three levels of inputs used to measure fair value:

Level 1: quoted prices in active markets for identical assets or liabilities;

Level 2: inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; or

Level 3: unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The Company’s assets measured at fair value on a recurring basis, including cash equivalents, which are subject to the fair value disclosure requirements, are as follows:

	Fair Value Measurements at Reporting Date Using
June 30, 2015	Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Inputs		Significant Unobservable Inputs

If quoted prices in active markets for identical assets and liabilities are not available to determine fair value, then the Company uses quoted prices for similar assets and liabilities or inputs other than the quoted prices that are observable, either directly or indirectly. This pricing methodology applies to the Company’s Level 2 investments.

14. Income Taxes

For the three months ended June 30, 2015 and 2014, the Company recorded tax provisions of $3.9 million and $1.8 million, respectively. For the six months ended June 30, 2015 and 2014, the Company recorded tax provisions of $6.7 million and $3.1 million, respectively. The tax provision for the three and six months ended June 30, 2015 primarily pertained to the mix of pre-tax profits generated by the Company’s U.S., Japanese and Swiss subsidiaries and pre-tax profits generated by the Company’s U.S. and Swiss subsidiaries for the three and six months ended June 30, 2014.

The Company will continue to evaluate its valuation allowance position in each jurisdiction on a regular basis and may be in a position to reverse the valuation allowance on the deferred tax assets of its Swiss subsidiary in 2015. The potential tax benefit of such reversal would be approximately $150,000 if recognized in 2015.

Uncertain Tax Positions

The Company had an outstanding income tax liability of approximately $1.1 million, including interest, for uncertain tax positions as of June 30, 2015. The amount represented the aggregate tax effect of differences between tax return positions and the amounts otherwise recognized in the Company’s Condensed Consolidated Financial Statements. As of June 30, 2015, $263,000 is reflected as other current liabilities and $823,000 is reflected as other liabilities in the accompanying Condensed Consolidated Balance Sheets. The liability for uncertain tax positions as of June 30, 2015 mainly pertained to the Company’s interpretation of nexus in certain states related to revenue sourcing for state income tax purposes. During the three and six months ended June 30, 2015, the liability for income taxes has increased approximately $199,000 and increased approximately $244,000, respectively. These changes in the liability are primarily related to the filing positions taken in various jurisdictions related to income tax nexus.

Segment Reporting [Abstract]

Segment Reporting Disclosure [Text Block]

15. Segment Reporting

In the first quarter of 2015, the Company made a number of strategic and operational changes to its business, including re-evaluating and accelerating its pipeline to focus on clinical programs that it believes hold the most promise for patients, the highest likelihood for regulatory approval, and the strongest potential for commercial return. As a result of such changes, the Company combined its reportable geographic segments of Asia, the Americas and Europe into one operating segment: the development and commercialization of pharmaceutical products. This change reflects the manner in which information is now being presented internally and used by the Company’s chief operating decision maker, the Company’s Chief Executive Officer, to allocate resources and assess performance.

Reportable segments include those that meet any of the following quantitative thresholds a) it's reported revenue, including sales to external customers and intersegment sales or transfers is 10 percent or more of the combined revenue, internal and external, of all operating segments b) the absolute amount of its reported profit or loss is 10 percent or more of the greater, in absolute amount of 1) the combined reported profit of all operating segments that did not report a loss or 2) the combined reported loss of all operating segments that did report a loss c) its assets are 10 percent or more of the combined assets of all operating segments.

Accounting Policies, by Policy (Policies)	6 Months Ended
Accounting Policies, by Policy (Policies)	Jun. 30, 2015
Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	*Basis of Presentation* The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles in the United States of America (GAAP) and the rules and regulations of the U.S. Securities and Exchange Commission (SEC) for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the Company’s Consolidated Financial Statements as of and for the year ended December 31, 2014 included in the Company’s Annual Report on Form 10-K, which was filed with the SEC on March 9, 2015. The financial information as of June 30, 2015, the three and six months ended June 30, 2015, and the three and six months ended June 30, 2014 is unaudited. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. In the opinion of the Company’s management, all adjustments, consisting only of normal recurring adjustments or accruals, considered necessary for a fair statement of the results of these interim periods have been included. The results of the Company’s operations for any interim period are not necessarily indicative of the results that may be expected for any other interim period or for a full fiscal year. The Condensed Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries: Sucampo AG (SAG) based in Zug, Switzerland, through which the Company conducts certain of its worldwide and European operations; Sucampo Pharma, LLC (SPL) based in Osaka, Japan, through which the Company conducts its Asian operations; Sucampo Pharma Americas LLC, (SPA) based in Bethesda, Maryland, through which the Company conducts its North American operations; and Sucampo Pharma Europe, Ltd., (SPE) based in Oxford, United Kingdom. All significant inter-company balances and transactions have been eliminated. The preparation of financial statements in conformity with GAAP requires management to make estimates that affect the reported amounts of assets and liabilities at the date of the financial statements, disclosure of contingent assets and liabilities, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Certain Risks, Concentrations and Uncertainties Financial instruments that potentially subject the Company to significant concentrations of credit risk consist of cash and cash equivalents, restricted cash, investments and receivables. The Company places its cash, cash equivalents and restricted cash with highly rated financial institutions and invests its excess cash in highly rated investments. As of June 30, 2015 and December 31, 2014, approximately $32.5 million, or 25.4%, and $37.0 million, or 33.6%, respectively, of the Company’s cash, cash equivalents, restricted cash and investments were issued or insured by the U.S. government or U.S. government agencies. The Company has not experienced any losses on these accounts related to amounts in excess of insured limits. Revenues from Takeda, an unrelated party, accounted for 53.6% and 68.1% of the Company’s total revenues for the three months ended June 30, 2015 and 2014, respectively, and 57.4% and 69.6% for the six months ended June 30, 2015 and 2014, respectively. Revenues from Mylan (formerly Abbott), an unrelated party, accounted for 41.6% and 30.0% of the Company’s total revenues for the three months ended June 30, 2015 and 2014, respectively, and 39.8% and 28.8% for the six months ended June 30, 2015 and 2014, respectively. Accounts receivable, unbilled accounts receivable and product royalties receivable from Takeda accounted for 73.7% and 88.5% of the Company’s total accounts receivable, unbilled accounts receivable and product royalties receivable at June 30, 2015 and December 31, 2014, respectively. The Company depends significantly upon collaborations with Takeda and Mylan, and its revenues may be impacted if these relationships are disrupted.
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued authoritative guidance which sets forth a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. The guidance is effective for annual reporting periods, including interim reporting periods within those periods, beginning after December 15, 2016, and early adoption is not permitted. Companies may use either a full retrospective or a modified retrospective approach to adopt this guidance. The Company is currently evaluating the impact of this guidance. On July 9, 2015, the FASB voted to defer the effective date of the above mentioned revenue recognition guidance by one year to December 15, 2017 for interim and annual reporting periods beginning after that date and permitted early adoption of the standard, but not before the original effective date of December 15, 2016
