Description of Business and Summary of Significant Accounting Policies | 1. Description of Business and Summary of Significant Accounting Policies Chiasma, Inc. is a clinical-stage biopharmaceutical company incorporated in 2001 under the laws of the State of Delaware. Chiasma, Inc. is headquartered in Massachusetts and has two wholly owned subsidiaries; Chiasma (Israel) Ltd., and Chiasma Securities Corp, collectively referred to as “the Company,” “we,” “us,” “our” or “Chiasma”. We are a clinical-stage biopharmaceutical company focused on improving the lives of patients who face challenges associated with their existing treatments for rare and serious chronic disease. Employing our proprietary Transient Permeability Enhancer (“TPE”) technology platform, we seek to develop oral medications that are currently available only as injections. We are currently developing oral octreotide capsules, conditionally trade-named “MYCAPSSA”, our sole TPE platform-based clinical product 56 adult acromegaly patients. We initiated this trial following our agreement with the United States Food and Drug Administration (“FDA”) on the design of the trial, reached through a Special Protocol Assessment in August 2017. Acromegaly is a rare and debilitating condition that results in the body’s production of excess growth hormone. Octreotide is an analog of somatostatin, a natural inhibitor of growth hormone secretion. Octreotide capsules have been granted orphan designation in the United States and the European Union for the treatment of acromegaly. We retain worldwide rights to develop and commercialize octreotide capsules with no royalty obligations to third parties. We are also currently conducting an international Phase 3 clinical trial, referred to as MPOWERED, of oral octreotide capsules for the maintenance treatment of adult patients with acromegaly to support regulatory approval in the European Union by the European Medicines Agency (“EMA”). The MPOWERED trial is a global, randomized, open-label and active-controlled 15-month trial initially designed to enroll up to 150 In October 2018, 80 patients were randomized following the six-month run-in phase in the MPOWERED trial. In October 2018, we also elected to resume enrollment in the trial in an effort to enroll up to 15 additional patients exclusively located in the United States in order to gain further U.S. investigator and patient experience with octreotide capsules. Liquidity We have incurred significant losses from operations since our inception and expect losses to continue for at least the next several years. We are heavily dependent on the regulatory approval and subsequent commercial success of our product candidate, octreotide capsules for the treatment of acromegaly, in the United States and European Union, both of which may never occur. We expect to continue with international Phase 3 CHIASMA OPTIMAL clinical trial of octreotide capsules in acromegaly and our ongoing international Phase 3 MPOWERED clinical trial of octreotide capsules in acromegaly to support potential regulatory approval in the European Union. We continue to focus our resources on the development of octreotide capsules for the maintenance treatment of adult acromegaly patients. We currently expect our existing cash, cash equivalents and marketable securities to fund our operations for at least one year after the date these condensed consolidated financial statements are issued. We expect to continue to incur significant operating losses for the foreseeable future. Successful transition to attaining profitable operations is dependent upon achieving a level of revenues adequate to support our cost structure. We plan to continue to fund our losses from operations and capital funding needs from existing balances of cash, cash equivalents and marketable securities and potentially through the issuance of debt and/or equity or through collaborations or license agreements with other companies. Debt or equity financing may not be available on a timely basis on terms acceptable to us, or at all. If we are not able to secure adequate additional funding, we may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible, suspend or curtail our planned development of octreotide capsules, or delay our commercial preparations or launch readiness even if octreotide capsules are approved by the FDA or EMA. Any of these actions could materially harm our business, results of operations and future prospects. Failure to obtain regulatory approval of octreotide capsules in acromegaly will prevent us from commercializing the product candidate, which could raise significant concerns about our continued viability as a business. On April 2, 2019, we completed a follow-on underwritten public offering of 6,315,790 shares of common stock at a public offering price of $4.75 per share, before underwriting discounts and commissions, and on April 3, 2019, we closed on the sale of an additional 947,368 shares of common stock pursuant to the underwriters’ option at a public offering price of $4.75 per share, before underwriting discounts and commissions. Aggregate gross proceeds were $34.5 million while net proceeds received after underwriting fees and offering expenses were approximately $32.2 million. On July 30, 2019, we completed a follow-on underwritten public offering of 10,000,000 shares of common stock at a public offering price of $5.50 per share, before underwriting discounts and commissions. Aggregate gross proceeds were $55.0 million while net proceeds received after underwriting fees and offering expenses were approximately $51.5 million. In addition, we granted the underwriters a 30-day option to purchase up to an additional 1,500,000 shares of our common stock at the public offering price, less underwriting discounts and commissions which has not yet been exercised. These offerings were made pursuant to a prospectus dated March 22, 2018 and prospectus supplements dated March 29, 2019 and July 26, 2019, respectively, in connection with drawdowns from our shelf registration statement on Form S-3, which the U.S. Securities and Exchange Commission (“SEC”) declared effective on May 3, 2018. Basis of Presentation We have prepared the accompanying unaudited condensed consolidated financial statements pursuant to the rules and regulations of the SEC regarding interim financial reporting. Accordingly, certain information and footnote disclosures required by accounting principles generally accepted in the United States (“U.S. GAAP”) for annual financial statements have been condensed or omitted. The information included in this quarterly report on Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2018. The year-end condensed consolidated balance sheet data presented for comparative purposes was derived from our audited financial statements but does not include all disclosures required by U.S. GAAP. In the opinion of management, we have prepared the accompanying unaudited condensed consolidated financial statements on the same basis as our audited financial statements, and these financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results of the interim periods presented. Interim results are not necessarily indicative of results for a full year or for any other subsequent interim period. Cash Equivalents Cash equivalents consist of highly liquid instruments that mature within three months or less from the date of purchase. Marketable Securities Our investments primarily consist of commercial paper and corporate and government debt securities. These marketable securities are classified as available-for-sale, and as such, are reported at fair value on our condensed consolidated balance sheets. Unrealized holding gains and losses are reported within accumulated other comprehensive income (loss) as a separate component of stockholders’ equity. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization, together with interest on securities, are included in other income, net, on our condensed consolidated statements of operations. If a decline in the fair value of a marketable security below our cost basis is determined to be other than temporary, such marketable security is written down to its estimated fair value as a new cost basis and the amount of the write-down is included in earnings as an impairment charge. The cost of securities sold is based on the specific identification method. Concentrations of credit risk Financial instruments that potentially subject us to significant concentration of credit risk consist primarily of cash, cash equivalents and marketable securities. We routinely maintain deposits in financial institutions in excess of government insured limits. Management believes that we are not exposed to significant credit risk as our deposits are held at financial institutions that management believes to be of high credit quality and we have not experienced any significant losses in these deposits. We regularly invest excess operating cash in deposits with major financial institutions and money market funds and in notes issued by the U.S. government, as well as in fixed income investments and U.S. bond funds, both of which can be readily purchased and sold using established markets. We believe that the market risk arising from our holdings of these financial instruments is mitigated based on the fact that many of these securities are either government backed or of high credit rating. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, and expenses, and the disclosure of contingent assets and liabilities as of and during the reporting period. We base these estimates and assumptions on historical experience when available, and on various factors that we believe to be reasonable under the specific circumstances. Significant estimates relied upon in preparing the accompanying condensed consolidated financial statements include, but are not limited to, accounting for stock-based compensation, income taxes, and accounting for certain accruals. We assess the above estimates on an ongoing basis; however, actual results could materially differ from those estimates. Recently Issued Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued new guidance which establishes a right-of-use model that requires a lessee to record an asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. A modified retrospective approach, which includes a number of optional practical expedients, is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. On January 1, 2019, we adopted this standard using a modified retrospective approach. As of January 1, 2019, we recorded a right-of-use asset of $0.3 million and an operating lease liability of $0.3 million. For additional information regarding how we are accounting for leases under this standard refer to Note 10. In June 2018, the FASB issued new guidance which changes certain aspects of the accounting for share-based payments granted to nonemployees. Under this guidance, most of the treatment for share-based payments granted to nonemployees would be aligned with the requirements for share-based payments granted to employees. The new standard is effective beginning January 1, 2019. We adopted this standard on January 1, 2019 and thus ceased the re-measurement of non-employee awards. The adoption of this standard did not have a material impact on our condensed consolidated financial statements. In June 2016, the FASB issued new guidance which will require more timely recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The new guidance requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. The new guidance also requires enhanced disclosures regarding significant estimates and judgments used in estimating credit losses. This guidance is effective January 1, 2020 and early adoption of this standard is permitted. We plan to adopt this standard on January 1, 2020. We are currently evaluating the impact the standard may have on our condensed consolidated financial statements. |
