Description of Business and Summary of Significant Accounting Policies | 1. Description of Business and Summary of Significant Accounting Policies Chiasma, Inc. is a biopharmaceutical company incorporated in 2001 under the laws of the State of Delaware. The Company is dedicated to improving the lives of patients suffering from orphan diseases by developing and commercializing novel oral therapies that are currently available only as injections. The Company has completed a multinational Phase 3 clinical trial of its most advanced Transient Permeability Enhancer (“TPE”) platform-based product candidate, octreotide capsules, for the treatment of acromegaly and its New Drug Application (“NDA”) was accepted for filing by the United States Food and Drug Administration (“FDA”) in August 2015. On the Prescription Drug User Fee Act (“PDUFA”) date of April 15, 2016, the FDA issued the Company a Complete Response Letter (“CRL”) regarding the NDA, indicating that the review is complete and the NDA is not ready for approval in its present form. The FDA expressed concerns regarding certain aspects of the Company’s single-arm, open-label Phase 3 clinical trial and strongly recommended that the Company conduct a randomized, double-blind and controlled trial that enrolls patients from the United States and is of sufficiently long duration to ensure that control of disease activity is stable at the time point selected for the primary efficacy assessment. In addition, the FDA advised that, during a recent site inspection, certain deficiencies were conveyed to the representative of one of the Company’s suppliers that would need to be resolved before approval. The Company has requested an End of Review meeting with the FDA to discuss the concerns the FDA raised in the CRL. Requesting the meeting does not necessarily mean that the FDA will grant the meeting in a timely manner, or at all. Even if the FDA grants the meeting, there are no assurances that such a meeting will lead to resolution of each of the concerns raised in the CRL or that it will not foreclose any otherwise available opportunity to meet with the FDA regarding the CRL or the NDA in the future. 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”. The Company’s product development facilities are in Israel. In addition to the regulatory uncertainty created by the CRL, the Company is also subject to risks common to companies in the biopharmaceutical development industry. There can be no assurance that the Company’s research and development will be successfully completed, that adequate protection for the Company’s intellectual property will be obtained, that any products developed will obtain required regulatory approval or that any approved products will be commercially viable. Even if the Company’s development efforts are successful, it is uncertain when, if ever, the Company will generate significant product sales. The Company operates in an environment of rapid technological change and substantial competition from pharmaceutical and biotechnology companies. Liquidity The Company has incurred significant losses from operations since its inception and expects losses to continue for at least the next several years. The Company is heavily dependent on the regulatory approval and subsequent commercial success of its lead product candidate, octreotide capsules for the treatment of acromegaly in the United States and Europe, both of which may never occur. The Company expects to continue to conduct its recently initiated international Phase 3 clinical trial of octreotide capsules in acromegaly to support potential regulatory approval in Europe. The Company is currently revisiting all areas of investment and resources in light of our recent receipt of the CRL to potentially enable an overall reduction of its 2016 expenses and extension of our cash runway beyond mid-2017. As a public company, the Company will continue to incur costs associated with operating as a public company. Therefore, the Company expects 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 the Company’s cost structure. As a result of the CRL received from the FDA in April 2016, the Company’s ability to generate product revenues has been delayed indefinitely. The Company plans to continue to fund its 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 the Company, or at all. If the Company is not able to secure adequate additional funding, the Company may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible, or suspend or curtail planned programs. Any of these actions could materially harm the Company’s business, results of operations and future prospects. Basis of Presentation The Company has prepared the accompanying unaudited condensed consolidated financial statements pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“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 the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. 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, the Company has prepared the accompanying unaudited condensed consolidated financial statements on the same basis as its 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. The results of operations for the three months ended March 31, 2016, are not necessarily indicative of the operating results for the full year or for any other subsequent interim period. On July 21, 2015, the Company completed the sale of 7,319,750 shares of its common stock in its IPO, at a price to the public of $16.00 per share, resulting in net proceeds to the Company of approximately $106.5 million after deducting underwriting discounts and commissions and offering expenses payable by the Company. In preparation for the IPO, the Company’s board of directors and stockholders approved a 1-for-9.132 reverse stock split (the “Reverse Split”) of the Company’s common stock effective June 30, 2015. In connection with the closing of the IPO on July 21, 2015, all of the Company’s outstanding redeemable convertible preferred stock automatically converted into 16,403,011 shares of common stock. All previously reported common stock share amounts in the accompanying financial statements and related notes have been retroactively adjusted to reflect the reverse stock split. The significant increase in shares outstanding in July 2015 is expected to impact the year-over-year comparability of the Company’s net loss per share calculations throughout 2016. Cash Equivalents Cash and cash equivalents consist of highly liquid instruments purchased with an original maturity of three months or less at the date of purchase. Marketable Securities The Company’s investments primarily consisted of commercial paper, corporate and government debt securities. These marketable securities are classified as available-for-sale, and as such, are reported at fair value on the Company’s condensed consolidated balance sheets. Unrealized holding gains and losses are reported within accumulated other comprehensive income 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 expense, net, on the Company’s condensed consolidated statements of operations. If a decline in the fair value of a marketable security below the Company’s 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 the Company to significant concentration of credit risk consist primarily of cash, cash equivalents, marketable securities and long-term restricted deposits. Periodically, the Company maintains deposits in financial institutions in excess of government insured limits. Management believes that the Company is not exposed to significant credit risk as the Company’s deposits are held at financial institutions that management believes to be of high credit quality and the Company has not experienced any significant losses in these deposits. The Company regularly invests 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. The Company believes that the market risk arising from its 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. The Company bases these estimates and assumptions on historical experience when available, and on various factors that it believes 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, the fair value of common stock and other equity instruments, accounting for stock-based compensation, present value of long-term purchase obligation, income taxes, useful lives of long-lived assets, and accounting for certain accruals. The Company assesses the above estimates on an ongoing basis; however, actual results could materially differ from those estimates. Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued new revenue recognition guidance which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most current revenue recognition guidance. The new standard also requires significantly expanded disclosures regarding the qualitative and quantitative information of an entity’s nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The guidance is currently effective for the Company in 2018. Early adoption is permitted in 2017. The Company is currently evaluating the impact the standard may have on its consolidated financial statements. In August 2014, the FASB issued new guidance which requires management to assess an entity’s ability to continue as a going concern and to provide related disclosures in certain circumstances. The requirements of the standard will be effective for the annual and interim financial statement periods ending after December 15, 2016, with early adoption permitted. The Company adopted this guidance effective January 2016. The adoption of this standard did not have a material impact on the Company’s condensed consolidated financial statements. In April 2015, the FASB issued new guidance which requires the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability, consistent with the current treatment of debt discounts. The Company adopted this guidance effective January 2016. The adoption of this standard did not have a material impact on the Company’s condensed consolidated balance sheet. In July 2015, the FASB issued new guidance which requires an entity to measure inventory at the lower of cost and net realizable value. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. This guidance does not apply to inventory that is measured using last-in, first-out. The guidance is effective for the Company in 2017. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements. In November 2015, the FASB issued new guidance which requires all deferred income taxes be presented on the balance sheet as noncurrent. The new guidance is intended to simplify financial reporting by eliminating the requirement to classify deferred taxes between current and noncurrent. The guidance is effective for the Company in 2017. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements. In February 2016, the 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. The guidance is effective for the Company in 2019. A modified retrospective transition approach 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. The Company is currently evaluating the impact the standard may have on its consolidated financial statements. In March 2016, the FASB issued guidance simplifying aspects of the accounting for employee share-based payments, including the accounting for income taxes, forfeitures, statutory withholding requirements, and classification on the statement of cash flows. The standard is effective for interim and annual periods beginning after December 15, 2016, with early adoption permitted. The Company is currently evaluating the impact the standard may have on its consolidated financial statements. |
