Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Organization, Basis of Presentation and Liquidity | 1. Organization, Basis of Presentation and Liquidity Organization Aradigm Corporation (the “Company,” “we,” “our,” or “us”) is a California corporation, incorporated in 1991, focused on the development and commercialization of drugs delivered by inhalation for the treatment and prevention of severe respiratory diseases. The Company’s principal activities to date have included conducting research and development and developing collaborations. Management does not anticipate receiving revenues from the sale of any of its products during the 2016 fiscal year. The Company operates as a single operating segment. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Certain information and footnote disclosures normally included in financial statements prepared in accordance with United States GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). In the opinion of management, the financial statements reflect all adjustments, which are of a normal recurring nature, necessary for fair presentation. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015, as filed with the SEC on March 30, 2016 (the “2015 Annual Report on Form 10-K”). The results of the Company’s consolidated operations for the interim periods presented are not necessarily indicative of operating results for the full fiscal year or any future interim period. The consolidated balance sheet at December 31, 2015 has been derived from the audited financial statements at that date, but does not include all of the information and footnotes required by GAAP for complete financial statements. For further information, please refer to the consolidated financial statements and notes thereto included in the 2015 Annual Report on Form 10-K. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All inter-company accounts and transactions have been eliminated in consolidation. Liquidity The Company has incurred significant operating losses and negative cash flows from operations. At June 30, 2016, the Company had an accumulated deficit of $422.3 million, working capital of $30.5 million and shareholders’ equity of $15.5 million. The Company had cash and cash equivalents of approximately $31.2 million as of June 30, 2016. Management believes that this amount, together with the proceeds from the second closing of the convertible debt transaction described in Note 7 and Note 11 below, will be sufficient to meet its obligations through at least December 31, 2016. However, the Company’s business strategy will require it to raise additional capital through equity or debt financing(s), strategic transactions or otherwise, to develop and seek regulatory approval of the Company’s investigational product candidate. In addition, the Company may decide to raise capital opportunistically. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Use of Estimates The preparation of financial statements, in conformity with GAAP, requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These estimates include useful lives for property and equipment and related depreciation calculations, accruals for clinical trial expenses, assumptions for valuing options and warrants, and income taxes. Actual results could differ from these estimates. Cash and Cash Equivalents All highly liquid investments with maturities of three months or less at the time of purchase are classified as cash equivalents. Restricted Cash The Company classifies transfers to the restricted cash balance in the statement of cash flows based on the nature of the restriction. At June 30, 2016, the Company has $1.8 million in restricted cash held in an interest bearing escrow account for the purpose of making future interest payments on the Convertible Notes, see Note 7. The Company is required to maintain such deposits sufficient to pay all required payments of interest through May 1, 2017. Property and Equipment The Company records property and equipment at cost and calculates depreciation using the straight-line method over the estimated useful lives of the respective assets. Machinery and equipment includes external costs incurred for validation of the equipment. The Company does not capitalize internal validation expense. Computer equipment and software includes capitalized computer software. All of the Company’s capitalized software is purchased; the Company has no internally-developed computer software. Leasehold improvements are amortized over the shorter of the term of the lease or useful life of the improvement. Impairment of Long-Lived Assets The Company reviews for impairment whenever events or changes in circumstances indicate that the carrying amount of property and equipment may not be recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. In the event that such cash flows are not expected to be sufficient to recover the carrying amount of the assets, the assets are written down to their estimated fair values and the loss is recognized in the consolidated statements of operations. Convertible Instruments The Company accounts for hybrid contracts that feature conversion options in accordance with generally accepted accounting principles in the United States. ASC 815, Derivatives and Hedging Activities The Company accounts for convertible instruments (when it has determined that the embedded conversion options should be bifurcated from their host instruments) in accordance with ASC 815. Under ASC 815, a portion of the proceeds received upon the issuance of the hybrid contract is allocated to the fair value of the derivative. The derivative is subsequently marked to market at each reporting date based on current fair value, with the changes in fair value reported in results of operations. Warrants Issued in Connection with Financings For warrants where there is a possibility that the Company may have to settle the warrants in cash, the Company records the fair value of the issued warrants as a liability at each reporting date and records changes in the estimated fair value as a non-cash gain or loss in the condensed consolidated statements of operations. The fair values of these warrants have been determined using the Black Scholes Merton Option Pricing valuation model (the “Black-Scholes Model”). The Black-Scholes Model provides for assumptions regarding volatility, call and put features and risk-free interest rates within the total period to maturity. These values are subject to a significant degree of judgment on the part of the Company. Accounting for Costs Associated with Exit or Disposal Activities The Company recognizes a liability for the cost associated with an exit or disposal activity that is measured initially at its fair value in the period in which the liability is incurred. The Company accounted for the partial sublease of its headquarters building as an exit activity and recorded the sublease loss in its Condensed Consolidated Statement of Operations and Comprehensive Loss (see Note 5). Costs to terminate an operating lease or other contracts are (a) costs to terminate the contract before the end of its term or (b) costs that will continue to be incurred under the contract for its remaining term without economic benefit to the entity. In periods subsequent to initial measurement, changes to the liability are measured using the credit-adjusted risk-free rate that was used to measure the liability initially. Revenue Recognition Contract revenues consist of revenues from grants, collaboration agreements and feasibility studies. License and collaboration revenue is primarily generated through agreements with strategic partners for the development and commercialization of our product candidates. The terms of the agreement typically include non-refundable upfront fees, funding of research and development activities, payments based upon achievement of milestones and royalties on net product sales. The Company recognizes revenue under the provisions of the Securities and Exchange Commission issued Staff Accounting Bulletin 104, Topic 13, Revenue Recognition Revised and Updated (“SAB Topic 13”) and ASC 605-25, Revenue Recognition-Multiple Elements. Revenue for arrangements not having multiple deliverables, as outlined in ASC 605-25, is recognized once costs are incurred and collectability is reasonably assured. Revenue is recognized when there is persuasive evidence that an arrangement exists, delivery has occurred, the price is fixed and determinable and collection is reasonably assured. Multiple-deliverable arrangements, such as license and development agreements, are analyzed to determine whether the deliverables can be separated or whether they must be accounted for as a single unit of accounting. When deliverables are separable, consideration received is allocated to the separate units of accounting based on the relative selling price method and the appropriate revenue recognition principles are applied to each unit. When the Company determines that an arrangement should be accounted for as a single unit of accounting, it must determine the period over which the performance obligations will be performed and revenue will be recognized. The Company estimates its performance period used for revenue recognition based on the specific terms of each agreement, and adjusts the performance periods, if appropriate, based on the applicable facts and circumstances. Significant management judgment may be required to determine the level of effort required under an arrangement and the period over which the Company is expected to complete its performance obligations under the arrangement. If the Company cannot reasonably estimate when its performance obligations either are completed or become inconsequential, then revenue recognition is deferred until the Company can reasonably make such estimates. Revenue is then recognized over the remaining estimated period of performance using the cumulative catch-up method. The Company adopted the provisions of Accounting Standards Update No. 2009-13, Revenue Recognition (Topic 605); Multiple-Deliverable Revenue Arrangements (“ASU 2009-13”) for new and materially modified arrangements originating on or after January 1, 2010. ASU 2009-13 provides updated guidance on how the deliverables in an arrangement should be separated, and how consideration should be allocated, and it changes the level of evidence of standalone selling price required to separate deliverables by allowing a vendor to make its best estimate of the standalone selling price of deliverables when vendor-specific objective evidence or third-party evidence of selling price is not available. The Company allocates non-contingent consideration to each stand-alone deliverable based upon the relative selling price of each element. When applying the relative selling price method, the Company determines the selling price for each deliverable using vendor-specific objective evidence, or VSOE, of selling price, if it exists, or third-party evidence, or TPE, of selling price, if it exists. If neither VSOE nor TPE of selling price exist for a deliverable, the Company uses best estimated selling price, or BESP, for that deliverable. Assuming the elements meet the revenue recognition guidelines, the revenue recognition methodology prescribed for each unit of accounting is summarized below: Upfront Fees Funded Research and Development and Grant Revenue Milestones Royalties Research and Development Research and development expenses consist of costs incurred for company-sponsored, collaborative and contracted research and development activities. These costs include direct and research-related overhead expenses. The Company expenses research and development costs as such costs are incurred. Stock-Based Compensation The Company accounts for share-based payment arrangements in accordance with ASC 718, Compensation-Stock Compensation Equity-Equity Based Payments to Non-Employees Income Taxes The Company makes certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments occur in the calculation of certain tax assets and liabilities, which arise from differences in the timing of recognition of revenue and expense for tax and financial statement purposes. As part of the process of preparing the financial statements, the Company is required to estimate income taxes in each of the jurisdictions in which it operates. This process involves the Company estimating its current tax exposure under the most recent tax laws and assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities which are included in the Company’s consolidated balance sheets. The Company estimated its current tax exposure to be zero as it expects to be able to utilize its net operating loss carryovers (NOLs) to offset the income recognized in the quarter and year to date. The Company has updated its Section 382 analysis through December 31, 2015 and noted no additional changes since the last change in 2010. The Company assesses the likelihood that it will be able to recover its deferred tax assets. The Company considers all available evidence, both positive and negative, including the historical levels of income and losses, expectations and risks associated with estimates of future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for a valuation allowance. If the Company does not consider it more likely than not that it will recover its deferred tax assets, the Company records a valuation allowance against the deferred tax assets that it estimates will not ultimately be recoverable. At June 30, 2016, and December 31, 2015 the Company believed that the amount of its deferred income taxes would not be ultimately recovered. Accordingly, the Company recorded a full valuation allowance for deferred tax assets. However, should there be a change in the Company’s ability to recover its deferred tax assets the Company would recognize a benefit to its tax provision in the period in which it determines that it is more likely than not that it will recover its deferred tax assets. Net Income/(Loss) Per Common Share Basic net income/(loss) per common share is computed using the weighted-average number of shares of common stock outstanding during the period less the weighted-average number of restricted shares of common stock subject to repurchase. Potentially dilutive securities were not included in the net loss per common share calculation for the three and six months ended June 30, 2016, and 2015 because the inclusion of such shares would have had an anti-dilutive effect. Comprehensive Income (Loss) Comprehensive loss refers to revenues, expenses, gains and losses that under U.S. GAAP are included in comprehensive loss but are excluded from net loss as these amounts are recorded directly as an adjustment to shareholders’ equity. Comprehensive loss for the periods presented was comprised solely of the Company’s consolidated net loss. There were no changes in equity that were excluded from the Company’s consolidated net loss for all periods presented. Recently Issued Accounting Pronouncements There have been no recent accounting pronouncements or changes in accounting pronouncements during the six months ended June 30, 2016, as compared to the recent accounting pronouncements described in the Company’s 2015 Annual Report on Form 10-K that are of significance or potential significance to the Company. |

Convertible Notes and Warrants | 7. Convertible Notes and Warrants On April 21, 2016, the Company entered into a securities purchase agreement to conduct a private offering (the “Convertible Note Financing”) consisting of $23 million aggregate principal amount of its 9% senior convertible notes convertible into shares of common stock (the “Convertible Notes”) and 263,436 warrants to purchase shares of the Company’s common stock (the “Warrants”). The Convertible Notes bear interest at a rate of 9% per year, payable semiannually in arrears on November 1 and May 1 of each year commencing on November 1, 2016. The Convertible Notes mature on May 1, 2021, unless earlier redeemed or converted. The Convertible Notes are senior unsecured and unsubordinated obligations; rank equal in right of payment to the Company’s existing and future unsecured indebtedness that is not subordinated and are effectively subordinated in right of payment to the Company’s existing and future secured indebtedness. The Convertible Notes are initially convertible into the Company’s common stock at a conversion rate of 191.9386 shares of common stock per $1,000 principal amount of Convertible Notes, representing an initial effective conversion price of $5.21 per share of common stock. The conversion rate may be subject to adjustment upon the occurrence of certain specified events as provided in the indenture governing the Convertible Notes, dated April 25, 2016 between the Company and U.S. Bank National Association, as trustee (the “Indenture”), but will not be adjusted for accrued but unpaid interest. Upon conversion of a Convertible Note, the Company will settle the conversion obligation in common stock equal to the conversion rate, together with a cash payment, if applicable. The Convertible Notes are convertible at the option of the holders at any time prior to April 29, 2021, except that, prior to shareholder approval of the issuance of the Convertible Notes, the Warrants and the underlying shares (“Shareholder Approval”), in the event that the aggregate number of shares of common stock issuable to the holders at any time would exceed 19.99% of the total number of shares of common stock outstanding on April 20, 2016 (the “Conversion Share Cap”), the number of shares issued in any such conversion would be capped at the Conversion Share Cap of 25.9476 shares per $1,000 principal amount of Convertible Notes. Shareholder approval was obtained on June 9, 2016 at which point the Conversion Share Cap was no longer applicable. Holders of the Convertible Notes who convert their Convertible Notes in connection with a make-whole fundamental change, as defined in the Indenture, may be entitled to a make-whole premium in the form of an increase to the conversion rate during a specified period following the effective date of the make-whole fundamental change. In addition, upon the occurrence of a fundamental change prior to the maturity date of the Convertible Notes, as defined in the Indenture, holders of the Convertible Notes may require the Company to purchase all or a portion of their Convertible Notes for cash at a price equal to 100% of the principal amount of the Convertible Notes to be purchased plus any accrued but unpaid interest to, but excluding, the fundamental change purchase date. On or after December 1, 2017, the Company may redeem for cash all or a portion of the Convertible Notes if the last reported sale price of the Company’s common stock is at any time equal to or greater than 200% of the conversion price then in effect for at least twenty trading days immediately preceding the date on which the Company provides notice of redemption, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. The Indenture provides for customary events of default which may result in the acceleration of the maturity of the Notes, including, but not limited to, cross acceleration to certain other indebtedness of the Company and its subsidiaries. In the case of an event of default arising from specified events of bankruptcy or insolvency or reorganization all outstanding Convertible Notes will become due and payable immediately without further action or notice. If any other event of default under the Indenture occurs or is continuing, the trustee or holders of at least 25% in aggregate principal amount of the then outstanding Convertible Notes may declare all of the Convertible Notes to be due and payable immediately. The Warrants have a five-year term and are exercisable at $5.21 per share of common stock. The exercise price is subject to adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events or upon any distributions of assets, including cash, stock or other property to the Company’s shareholders. The Warrants are exercisable commencing on the later of October 25, 2016 and the date of the public release of top line data related to the conclusion of the ORBIT-3 and ORBIT-4 Phase 3 pivotal clinical trials for the Company’s investigational product Pulmaquin ® In accounting for the Convertible Notes and Warrants, the Company bifurcated a derivative liability from the debt host and discounted the Convertible Notes for the estimated fair value of the conversion feature and the freestanding Warrants issued in connection with the Convertible Notes. The liability components were measured by estimating their fair value as of the commitment date. On June 9, 2016, the Company obtained Shareholder Approval, at which point the Conversion Share Cap was lifted. As a result, the bifurcated derivative and warrant liability met the equity classification criteria under ASC 815-40-25 and the liabilities were remeasured at fair value on June 9, 2016 and reclassified to permanent equity. The equity component will not be remeasured in subsequent periods provided that the component continues to meet the conditions necessary for equity classification. The excess of the aggregate face value of the Convertible Notes over the estimated fair value of the liability components is recognized as a debt discount which will be amortized over the term of the Convertible Notes using the effective interest rate method. Amortization of the debt discount is recognized as non-cash interest expense. On April 25, 2016, the initial closing of the Convertible Notes took place under which the Company raised $20 million from a total of two investors and issued 4,319 Warrants to one investor. Of the $20 million $19.9 million was financed by Grifols, a related party to the Company, see Note 8. There were 3,319,820 common shares underlying the conversion feature that was bifurcated as a derivative liability due to the Conversion Share Cap. The Company deposited $1.8 million of the net proceeds into an escrow account after the initial closing to fund, when due, the first two scheduled semi-annual interest payments on the notes. The effective interest rate of the liability component was equal to 22.9% for the three and six months ended June 30, 2016. The financing costs of $2.1 million incurred in connection with the issuance of the Convertible Notes were allocated to the derivative liability, warrant liability and Convertible Note components based on their relative fair values. At June 30, 2016, financing costs of $1.9 million were paid and financing costs of $264,000 were recorded in other accrued liabilities. Financing costs of $1.2 million allocated to the Convertible Note host are being amortized using the effective interest rate method and recognized as non-cash interest expense over the expected term of the Convertible Notes. Financing costs of $936,000 allocated to derivative and Warrant liability components were expensed as financing costs and are included in other expense in the Condensed Consolidated Statement of Operations and Comprehensive Loss. The derivative and warrant liabilities are measured at fair value using certain estimated inputs, which are classified within Level 3 of the valuation hierarchy. The following assumptions were used in the Black-Scholes Model to measure the fair value of the derivative and Warrants as of June 9, 2016 and April 21, 2016: June 9, 2016 April 21, 2016 Fair value of underlying stock – per share $ 4.48 $ 4.55 Risk-free interest rate 1.20 % 1.35 % Expected life (years) 4.9 5 Expected volatility 73.16 % 73.95 % Dividend yield 0.0 % 0.0 % The following table summarizes the activity in the derivative liability and the warrant liability for the three months ended June 30, 2016: Three Months Ended June 30, 2016 (in thousands) Fair Value Fair Value of Change in Reclassifications to Equity Fair Value 2016 Derivative liability $ — $ 8,748 $ (386 ) $ (8,362 ) $ — Warrant liability — 11 — (11 ) — Total $ — $ 8,759 $ (386 ) $ (8,373 ) $ — For the three and six months ended June 30, 2016, the Company recognized a gain of $386,000 and $500 on the derivative and warrant liabilities, respectively, related to the change in fair value from the date of commitment to the date the instruments met the equity classification criteria on June 9, 2016 at which point $8.4 million was reclassified from liabilities to equity.

Stock-Based Compensation and Stock Options and Awards | 9. Stock-Based Compensation and Stock Options and Awards The following table shows the stock-based compensation expense included in the accompanying Condensed Consolidated Statements of Operations and Comprehensive Loss for the three and six months ended June 30, 2016 and 2015 (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 Costs and expenses: Research and development $ 207 $ 139 $ 374 $ 217 General and administrative 193 118 426 225 Total stock-based compensation expense $ 400 $ 257 $ 800 $ 442 There was no capitalized stock-based employee compensation cost for the three and six months ended June 30, 2016 and 2015. Since the Company did not record a tax provision during the quarters ended June 30, 2016 and 2015, there was no recognized tax benefit associated with stock-based compensation expense. In March 2016, the Company granted to the officers certain stock option bonus grants, (contingent upon shareholder approval which was received in June 2016) whose vesting is dependent upon meeting certain specified company-wide performance goals. These options were granted at-the-money, contingently vest upon achievement of performance goals, and have contractual lives of ten years. Stock Option Plans: 2005 Equity Incentive Plan (the “2005 Plan”), and 2015 Equity Incentive Plan (the “2015” Plan) On March 13, 2015 the Board adopted and, on May 14, 2015 the Company’s shareholders approved, the 2015 Plan. The 2015 Plan replaces the Company’s 2005 Plan, which expired in March 2015. The 2015 Plan is intended to promote our long-term success and increase shareholder value by attracting, motivating, and retaining non-employee directors, officers, employees, advisors, consultants and independent contractors, and allows the flexibility to grant a variety of awards to eligible individuals, thereby strengthening their commitment to the Company’s success and aligning their interests with those of the Company’s shareholders. The Company did not request that shareholders authorize any new shares of Common Stock in connection with the approval of the 2015 Plan; rather, the shares authorized for issuance under the 2005 Plan were available for issuance under the 2015 Plan. In March 2016, the Company’s Board of Directors amended, and in June 2016 the Company’s shareholders approved, the amendment to the 2015 Plan increasing the shares of common stock authorized for issuance by 2,400,000 shares. Stock Option Activity The following is a summary of activity under the 2005 Plan and the 2015 Plan for the six months ended June 30, 2016: Shares Available for Balance at January 1, 2016 252,725 Increase in authorized shares 2,400,000 Options granted (707,823 ) Options cancelled 10,616 Awards granted (166,000 ) Balance at June 30, 2016 1,789,518 Options Outstanding Number of Shares Weighted Average Exercise Price Weighted Aggregate Outstanding at January 1, 2016 947,142 $ 11.40 Options granted 707,823 $ 4.10 Options cancelled (10,616 ) $ 73.79 Outstanding at June 30, 2016 1,644,349 $ 7.85 8.45 $ 199,720 Exercisable at June 30, 2016 464,966 $ 13.06 6.75 $ 1,708 During the six months ended June 30, 2016, zero stock options were exercised. The total amount of unrecognized compensation cost related to non-vested stock options and stock purchases, net of forfeitures, was $2.0 million as of June 30, 2016. This amount will be recognized over a weighted average period of 1.39 years. A summary of the Company’s unvested restricted stock award activities as of June 30, 2016 is presented below representing the maximum number of shares that could be earned or vested under the 2005 Plan and the 2015 Plan: Number Shares Weighted Average Grant Date Fair Balance at December 31, 2015 300 $ 57.60 Restricted shares granted 166,000 $ 3.87 Restricted share awards vested (4,687 ) $ 4.04 Balance at June 30, 2016 161,613 $ 3.97 For restricted stock awards the Company recognizes compensation expense over the vesting period for the fair value of the stock award on the measurement date. The Company retained purchase rights with respect to 162,000 shares of unvested restricted stock awards issued pursuant to stock purchase agreements at no cost per share as of June 30, 2016. As of June 30, 2016, there was approximately $515,000 of total unrecognized compensation costs, net of forfeitures, related to non-vested stock award which are expected to be recognized over a weighted average period of 2.51 years. |

Net Loss and Comprehensive Loss Per Common Share The Company computes basic net loss per common share using the weighted-average number of shares of common stock outstanding during the period less the weighted-average number of shares of common stock subject to repurchase. The effects of including the incremental shares associated with options, warrants and unvested restrictive are anti-dilutive, and are not included in the diluted weighted average number of shares of common stock outstanding for the six months ending June 30, 2016 and 2015. The Company excluded the following securities from the calculation of diluted net loss per common share for the six months ended June 30, 2016 and 2015, as their effect would be anti-dilutive (in thousands): Six months ended June 30, 2016 2015 Common shares underlying convertible notes 3,839 — Outstanding stock options 1,644 885 Unvested restricted stock 162 — Unvested restricted stock units 10 10 |

Subsequent Events [Abstract] | |
Subsequent Events | 11. Subsequent Events On July 14, 2016, the Company completed the second closing of its Convertible Note Financing. See Note 7 for information on the first closing of the Convertible Note Financing. The second closing occurred after the Company’s resale registration statement on Form S-1 relating to the Convertible Notes and the Warrants issued in connection with the private placement was declared effective by the Securities and Exchange Commission. The Company issued $3 million of the Convertible Notes and the Warrants in the second closing. The initial conversion price of the Convertible Notes is $5.21 per share of common stock, equivalent to an initial conversion rate of 191.9386 shares of common stock per $1,000 aggregate principal amount of notes. The Warrants are exercisable at an exercise price of $5.21 per share beginning on the later of 180 days after the date of issuance or the date the Company issues a press release announcing data related to the ORBIT-3 and ORBIT-4 Phase 3 pivotal clinical trials for the Company’s investigational product Pulmaquin inhaled ciprofloxacin. The Company deposited $215,250 of the net proceeds into an escrow account to fund, when due, the first two scheduled semi-annual interest payments on the notes. The Company intends to use the remaining net proceeds to fund the current clinical development and regulatory submission for licensure of Pulmaquin and for general corporate purposes. |
Summary of Significant Accoun17
Summary of Significant Accounting Policies (Policies) | 6 Months Ended |
Jun. 30, 2016 | |
Accounting Policies [Abstract] | |
Use of Estimates | Use of Estimates The preparation of financial statements, in conformity with GAAP, requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These estimates include useful lives for property and equipment and related depreciation calculations, accruals for clinical trial expenses, assumptions for valuing options and warrants, and income taxes. Actual results could differ from these estimates. |
Cash and Cash Equivalents | Cash and Cash Equivalents All highly liquid investments with maturities of three months or less at the time of purchase are classified as cash equivalents. |
Restricted Cash | Restricted Cash The Company classifies transfers to the restricted cash balance in the statement of cash flows based on the nature of the restriction. At June 30, 2016, the Company has $1.8 million in restricted cash held in an interest bearing escrow account for the purpose of making future interest payments on the Convertible Notes, see Note 7. The Company is required to maintain such deposits sufficient to pay all required payments of interest through May 1, 2017. |
Property and Equipment | Property and Equipment The Company records property and equipment at cost and calculates depreciation using the straight-line method over the estimated useful lives of the respective assets. Machinery and equipment includes external costs incurred for validation of the equipment. The Company does not capitalize internal validation expense. Computer equipment and software includes capitalized computer software. All of the Company’s capitalized software is purchased; the Company has no internally-developed computer software. Leasehold improvements are amortized over the shorter of the term of the lease or useful life of the improvement. |
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets The Company reviews for impairment whenever events or changes in circumstances indicate that the carrying amount of property and equipment may not be recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. In the event that such cash flows are not expected to be sufficient to recover the carrying amount of the assets, the assets are written down to their estimated fair values and the loss is recognized in the consolidated statements of operations. |
Convertible Instruments | Convertible Instruments The Company accounts for hybrid contracts that feature conversion options in accordance with generally accepted accounting principles in the United States. ASC 815, Derivatives and Hedging Activities The Company accounts for convertible instruments (when it has determined that the embedded conversion options should be bifurcated from their host instruments) in accordance with ASC 815. Under ASC 815, a portion of the proceeds received upon the issuance of the hybrid contract is allocated to the fair value of the derivative. The derivative is subsequently marked to market at each reporting date based on current fair value, with the changes in fair value reported in results of operations. |
Warrants Issued in Connection with Financings | Warrants Issued in Connection with Financings For warrants where there is a possibility that the Company may have to settle the warrants in cash, the Company records the fair value of the issued warrants as a liability at each reporting date and records changes in the estimated fair value as a non-cash gain or loss in the condensed consolidated statements of operations. The fair values of these warrants have been determined using the Black Scholes Merton Option Pricing valuation model (the “Black-Scholes Model”). The Black-Scholes Model provides for assumptions regarding volatility, call and put features and risk-free interest rates within the total period to maturity. These values are subject to a significant degree of judgment on the part of the Company. |
Accounting for Costs Associated with Exit or Disposal Activities | Accounting for Costs Associated with Exit or Disposal Activities The Company recognizes a liability for the cost associated with an exit or disposal activity that is measured initially at its fair value in the period in which the liability is incurred. The Company accounted for the partial sublease of its headquarters building as an exit activity and recorded the sublease loss in its Condensed Consolidated Statement of Operations and Comprehensive Loss (see Note 5). Costs to terminate an operating lease or other contracts are (a) costs to terminate the contract before the end of its term or (b) costs that will continue to be incurred under the contract for its remaining term without economic benefit to the entity. In periods subsequent to initial measurement, changes to the liability are measured using the credit-adjusted risk-free rate that was used to measure the liability initially. |
Revenue Recognition | Revenue Recognition Contract revenues consist of revenues from grants, collaboration agreements and feasibility studies. License and collaboration revenue is primarily generated through agreements with strategic partners for the development and commercialization of our product candidates. The terms of the agreement typically include non-refundable upfront fees, funding of research and development activities, payments based upon achievement of milestones and royalties on net product sales. The Company recognizes revenue under the provisions of the Securities and Exchange Commission issued Staff Accounting Bulletin 104, Topic 13, Revenue Recognition Revised and Updated (“SAB Topic 13”) and ASC 605-25, Revenue Recognition-Multiple Elements. Revenue for arrangements not having multiple deliverables, as outlined in ASC 605-25, is recognized once costs are incurred and collectability is reasonably assured. Revenue is recognized when there is persuasive evidence that an arrangement exists, delivery has occurred, the price is fixed and determinable and collection is reasonably assured. Multiple-deliverable arrangements, such as license and development agreements, are analyzed to determine whether the deliverables can be separated or whether they must be accounted for as a single unit of accounting. When deliverables are separable, consideration received is allocated to the separate units of accounting based on the relative selling price method and the appropriate revenue recognition principles are applied to each unit. When the Company determines that an arrangement should be accounted for as a single unit of accounting, it must determine the period over which the performance obligations will be performed and revenue will be recognized. The Company estimates its performance period used for revenue recognition based on the specific terms of each agreement, and adjusts the performance periods, if appropriate, based on the applicable facts and circumstances. Significant management judgment may be required to determine the level of effort required under an arrangement and the period over which the Company is expected to complete its performance obligations under the arrangement. If the Company cannot reasonably estimate when its performance obligations either are completed or become inconsequential, then revenue recognition is deferred until the Company can reasonably make such estimates. Revenue is then recognized over the remaining estimated period of performance using the cumulative catch-up method. The Company adopted the provisions of Accounting Standards Update No. 2009-13, Revenue Recognition (Topic 605); Multiple-Deliverable Revenue Arrangements (“ASU 2009-13”) for new and materially modified arrangements originating on or after January 1, 2010. ASU 2009-13 provides updated guidance on how the deliverables in an arrangement should be separated, and how consideration should be allocated, and it changes the level of evidence of standalone selling price required to separate deliverables by allowing a vendor to make its best estimate of the standalone selling price of deliverables when vendor-specific objective evidence or third-party evidence of selling price is not available. The Company allocates non-contingent consideration to each stand-alone deliverable based upon the relative selling price of each element. When applying the relative selling price method, the Company determines the selling price for each deliverable using vendor-specific objective evidence, or VSOE, of selling price, if it exists, or third-party evidence, or TPE, of selling price, if it exists. If neither VSOE nor TPE of selling price exist for a deliverable, the Company uses best estimated selling price, or BESP, for that deliverable. Assuming the elements meet the revenue recognition guidelines, the revenue recognition methodology prescribed for each unit of accounting is summarized below: Upfront Fees Funded Research and Development and Grant Revenue Milestones Royalties |
Research and Development | Research and Development Research and development expenses consist of costs incurred for company-sponsored, collaborative and contracted research and development activities. These costs include direct and research-related overhead expenses. The Company expenses research and development costs as such costs are incurred. |
Stock-Based Compensation | Stock-Based Compensation The Company accounts for share-based payment arrangements in accordance with ASC 718, Compensation-Stock Compensation Equity-Equity Based Payments to Non-Employees |
Income Taxes | Income Taxes The Company makes certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments occur in the calculation of certain tax assets and liabilities, which arise from differences in the timing of recognition of revenue and expense for tax and financial statement purposes. As part of the process of preparing the financial statements, the Company is required to estimate income taxes in each of the jurisdictions in which it operates. This process involves the Company estimating its current tax exposure under the most recent tax laws and assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities which are included in the Company’s consolidated balance sheets. The Company estimated its current tax exposure to be zero as it expects to be able to utilize its net operating loss carryovers (NOLs) to offset the income recognized in the quarter and year to date. The Company has updated its Section 382 analysis through December 31, 2015 and noted no additional changes since the last change in 2010. The Company assesses the likelihood that it will be able to recover its deferred tax assets. The Company considers all available evidence, both positive and negative, including the historical levels of income and losses, expectations and risks associated with estimates of future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for a valuation allowance. If the Company does not consider it more likely than not that it will recover its deferred tax assets, the Company records a valuation allowance against the deferred tax assets that it estimates will not ultimately be recoverable. At June 30, 2016, and December 31, 2015 the Company believed that the amount of its deferred income taxes would not be ultimately recovered. Accordingly, the Company recorded a full valuation allowance for deferred tax assets. However, should there be a change in the Company’s ability to recover its deferred tax assets the Company would recognize a benefit to its tax provision in the period in which it determines that it is more likely than not that it will recover its deferred tax assets. |
Net Income/(Loss) Per Common Share | Net Income/(Loss) Per Common Share Basic net income/(loss) per common share is computed using the weighted-average number of shares of common stock outstanding during the period less the weighted-average number of restricted shares of common stock subject to repurchase. Potentially dilutive securities were not included in the net loss per common share calculation for the three and six months ended June 30, 2016, and 2015 because the inclusion of such shares would have had an anti-dilutive effect. |
Comprehensive Income (Loss) | Comprehensive Income (Loss) Comprehensive loss refers to revenues, expenses, gains and losses that under U.S. GAAP are included in comprehensive loss but are excluded from net loss as these amounts are recorded directly as an adjustment to shareholders’ equity. Comprehensive loss for the periods presented was comprised solely of the Company’s consolidated net loss. There were no changes in equity that were excluded from the Company’s consolidated net loss for all periods presented. |
Recently Issued Accounting Pronouncements | Recently Issued Accounting Pronouncements There have been no recent accounting pronouncements or changes in accounting pronouncements during the six months ended June 30, 2016, as compared to the recent accounting pronouncements described in the Company’s 2015 Annual Report on Form 10-K that are of significance or potential significance to the Company. |
