Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
BASIS OF PRESENTATION AND MANAGEMENT PLANS | BASIS OF PRESENTATION AND MANAGEMENT PLANS The accompanying financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America. Any reference in these footnotes to applicable guidance is meant to refer to the authoritative U.S. generally accepted accounting principles (“GAAP”) as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”). The Company has not generated any revenue from product sales to date and, if the Company does not successfully obtain regulatory approval and commercialize any of its product candidates, the Company will not be able to generate product revenue or achieve profitability. As of December 31, 2017, the Company had an accumulated deficit of $322.5 million . The Company is subject to risks common to companies in the biotechnology industry and the future success of the Company is dependent on its ability to successfully complete the development of, and obtain regulatory approval for, its product candidates, manage the growth of the organization, obtain additional financing necessary in order to develop, launch and commercialize its product candidates, and compete successfully with other companies in its industry. |

Accounting Policies [Abstract] | |
SIGNIFICANT ACCOUNTING POLICIES | SIGNIFICANT ACCOUNTING POLICIES Use of Estimates The preparation of the financial statements in accordance with GAAP requires management to make certain estimates and judgments that affect the reported amounts of assets, liabilities, and expenses. Actual results could differ from those estimates. Consolidation All financial information presented includes the accounts of the Company and its wholly-owned subsidiaries, neither of which have had any material activity to date. All significant intercompany balances and transactions have been eliminated in consolidation. Revenue Recognition The Company has not yet generated any revenue from product sales. The Company’s source of revenue in 2017, 2016 and 2015 has been from grants. When grant funds are received after costs have been incurred, the Company accrues revenue and records a grant receivable. Cash received from grants in advance of incurring qualifying costs is recorded as deferred revenue, and recognized as revenue when qualifying costs are incurred. Cash and Cash Equivalents The Company considers all short-term, highly liquid investments with maturity of three months or less from the date of purchase to be cash equivalents. Investment Securities Consistent with its investment policy, the Company invests its cash allocated to fund its short-term liquidity requirements with prominent financial institutions in bank depository accounts and institutional money market funds. The Company invests the remainder of its cash in corporate debt securities and municipal bonds rated at least A quality or equivalent, U.S. Treasury notes and bonds and U.S. and state government agency-backed securities. The Company determines the appropriate classification of investment securities based on whether they represent the investment of funds available for current operations, as defined in ASC 210-10-45-1 and ASC 210-10-45-2. The Company reevaluates its classification as of each balance sheet date. All investment securities owned are classified as available-for-sale. The cost of securities sold is based on the specific identification method. Investment securities are recorded as of each balance sheet date at fair value, with unrealized gains and, to the extent deemed temporary, unrealized losses reported as accumulated other comprehensive gain (loss), a separate component of stockholders' equity. Interest and dividend income on investment securities, accretion of discounts and amortization of premiums and realized gains and losses are included in interest income in the statements of operations and comprehensive income (loss). An investment security is considered to be impaired when a decline in fair value below its cost basis is determined to be other than temporary. The Company evaluates whether a decline in fair value of an investment security is below its cost basis is other than temporary using available evidence. In the event that the cost basis of the investment security exceeds its fair value, the Company evaluates, among other factors, the amount and duration of the period that the fair value is less than the cost basis, the financial health of and business outlook for the issuer, including industry and sector performance, and operational and financing cash flow factors, overall market conditions and trends, the Company’s intent to sell the investment security and whether it is more likely than not the Company would be required to sell the investment security before its anticipated recovery. If a decline in fair value is determined to be other than temporary, the Company records an impairment charge in the statement of operations and comprehensive loss and establishes a new cost basis in the investment. Property and Equipment Leasehold improvements, furniture, equipment and software are recorded at cost and are depreciated using the straight-line method over the estimated useful lives of the related assets, which range from three to five years. Leasehold improvements are amortized over the shorter of the estimated useful life or the remaining lease term. Impairment of Long-Lived Assets The Company reviews long-lived assets for impairment when events or changes in business conditions indicate that their carrying value may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. There were no impairment charges related to long-lived assets for the years ended December 31, 2017, 2016 and 2015. Debt Issuance Costs Costs related to debt issuance are presented in the balance sheet as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts and are amortized using the effective interest method. Amortization of debt issuance costs are included in interest expense. Rent and Deferred Rent The Company recognizes rent expense for leases with increasing annual rents on a straight-line basis over the term of the lease. The amount of rent expense in excess of cash payments is classified as deferred rent. Any lease incentives received are deferred and amortized over the term of the lease. Fair Value of Financial Instruments Accounting standards include disclosure requirements around fair values used for certain financial instruments and establish a fair value hierarchy. The three-tier hierarchy prioritizes valuation inputs into three levels based on the extent to which inputs used in measuring fair value are observable in the market, as described further in Note 5. The Company believes the recorded values of its financial instruments, including cash and cash equivalents, accounts payable and accrued liabilities approximate their fair values due to the short-term nature of these instruments. Financial Instruments and Credit Risks Financial instruments that potentially subject the Company to credit risk include cash and cash equivalents, investment securities, and accounts receivable. Cash is deposited in demand accounts in federally insured domestic institutions to minimize risk. Insurance is provided through the Federal Deposit Insurance Corporation (“FDIC”) and Security Investor Protection Corporation (“SIPC”). Although the balances in these accounts exceed the federally insured limit from time to time, the Company has not incurred losses related to these deposits. Equity Issuance Costs Equity issuance costs represent costs paid to third parties in order to obtain equity financing. These costs have been netted against the proceeds of the equity issuances. Licenses and Patents Licenses and patent costs for technologies that are utilized in research and development and have no alternative future use are expensed as incurred. Costs related to the license of patents from third parties and internally developed patents are classified as research and development expenses. Legal costs related to patent applications and maintenance are classified as general and administrative expenses. Clinical Trials The Company estimates its clinical trial expense accrual for a given period based on the number of patients enrolled at each site, estimated cost per patient, and the length of time each patient has been in the trial, less amounts previously billed. These accruals are recorded in accrued expenses and other current liabilities, and the related expense is recorded in research and development expense. Research and Development Research and development expenses consist of expenses incurred in performing research and development activities, including compensation and benefits for research and development employees and consultants, facilities expenses, overhead expenses, cost of laboratory supplies, manufacturing expenses, fees paid to third parties and other outside expenses. Research and development costs are expensed as incurred. Clinical trial and other development costs incurred by third parties are expensed as the contracted work is performed. The Company accrues for costs incurred as the services are being provided by monitoring the status of the clinical trial or project and the invoices received from its external service providers. The Company estimates depend on the timeliness and accuracy of the data provided by the vendors regarding the status of each project and total project spending. The Company adjusts its accrual as actual costs become known. Where contingent milestone payments are due to third parties under research and development arrangements, the milestone payment obligations are expensed when the milestone events are achieved. Collaboration Agreements The Company enters into collaboration agreements that include varying arrangements regarding which parties perform and bear the costs of research and development activities. The Company may share the costs of research and development activities with a collaborator, or the Company may be reimbursed for all or a significant portion of the costs of the Company's research and development activities. The Company records its internal and third-party development costs associated with these collaborations as research and development expenses. When the Company is entitled to reimbursement of all or a portion of the research and development expenses that it incurs under a collaboration, the Company records those reimbursable amounts as a deduction to the research and development expenses. If the collaboration is a cost-sharing arrangement in which both the Company and its collaborator perform development work and share costs, the Company also recognizes, as research and development expenses in the period when its collaborator incurs development expenses, the portion of the collaborator's development expenses that the Company is obligated to reimburse. Contract Manufacturing Services Contract manufacturing services are expensed as incurred. Prepaid expenses are capitalized and amortized as services are performed. Share-Based Compensation The Company accounts for its share-based compensation in accordance with ASC 718, Compensation — Stock Compensation , which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees and directors to be recognized in the financial statements, based on their fair value. The Company measures share-based compensation to consultants in accordance with ASC 505-50, Equity-Based Payments to Non-Employees , and recognizes the fair value of the award over the period the services are rendered. The Company uses the Black-Scholes option-pricing model to estimate the fair value of stock option awards. The fair value is recognized as expense, net of estimated forfeitures, over the requisite service period, which is generally the vesting period of the respective award on a straight-line basis. Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. This method also requires the recognition of future tax benefits such as net operating loss and tax credit carry forwards, to the extent that realization of such benefits is more likely than not. A valuation allowance is recorded when the realization of future tax benefits is uncertain. The Company records a valuation allowance for the full amount of deferred tax assets, which would otherwise be recorded for tax benefits relating to the operating loss and tax credit carryforwards, as realization of such deferred tax assets cannot be determined to be more likely than not. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the statement of operations in the period that includes the enactment date. On December 22, 2017, the U.S. government enacted tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “2017 Tax Act”). The 2017 Tax Act significantly revises how U.S. taxes corporations. The Company is currently evaluating provisions of the 2017 Tax Act, which among other things, lowers the U. S. corporate income tax rate from 35% to 21% and moves toward a territorial tax system. As a result, an adjustment has been recorded to the deferred tax asset and a corresponding adjustment to the full valuation allowance. As the Company does not have all of the necessary information to analyze all income tax effects of the 2017 Tax Act, the Company will continue to evaluate tax reform and adjust the provisional amounts related to deferred income tax as additional information is obtained. The Company expects to complete a detailed analysis no later than the fourth quarter of 2018. The Company accounts for uncertain tax positions in accordance with the provisions of ASC 740, Income Taxes . When uncertain tax positions exist, the Company recognizes the tax benefit of tax positions to the extent that the benefit will more likely than not be realized. The determination as to whether the tax benefit will more likely than not be realized is based upon the technical merits of the tax position as well as consideration of the available facts and circumstances. As of December 31, 2017, 2016 and 2015, the Company had no uncertain tax positions and no interest or penalties have been charged to the Company for the years ended December 31, 2017, 2016 and 2015. If incurred, the Company will classify any interest and penalties as a component of interest expense and operating expense, respectively. The Company is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The tax years 2005 through 2017 remain open to examination by the Internal Revenue Service. Comprehensive Loss Comprehensive income (loss) is defined as the change in equity of a business enterprise during a period, from transactions, and other events and circumstances from non-owner sources. Components of comprehensive income (loss) includes, among other items, unrealized gains and losses on the changes in fair value of investments. These components are added, net of their related tax effect, to the reported net income (loss) to arrive at comprehensive income (loss). The components of accumulated other comprehensive loss at December 31, 2017 and 2016, on the Company’s balance sheet was comprised of the net unrealized holding losses on the Company’s investment securities. See Note 5 for further detail of the unrealized holding gains and losses on the Company’s investment securities. Net Loss and Net Loss per Share of Common Stock Attributable to Common Stockholders Basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of share of common stock outstanding during the period without consideration for common stock equivalents. The following outstanding shares of common stock equivalents were excluded from the computations of diluted net loss per shares of common stock attributable to common stockholders for the periods presented as the effect of including such securities would be anti-dilutive.

The classification guidance under ASU No. 2016-09 requires the recognition of excess tax benefits from share-based compensation arrangements as a discrete item within income tax benefit rather than additional paid-in capital and the classification guidance requiring presentation of excess tax benefits from share-based compensation arrangements as an operating activity on the statement of cash flows, rather than as a financing activity. The adoption of ASU No 2016-09 had no immediate impact on the Company's financial statements and related disclosures because the Company does not currently recognize a tax benefit related to share-based compensation expense as it maintains net operating loss carryforwards and has established a valuation allowance against the entire net deferred tax asset as of December 31, 2017. Further, the Company has elected to continue to estimate the number of stock-based awards expected to vest, as permitted by ASU 2016-09, rather than electing to account for forfeitures as they occur. In August 2016, the FASB issued ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments,” which provides guidance on the classification of certain cash receipts and payments in the statement of cash flows. The pronouncement is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods. Earlier application is permitted in any interim or annual period. The Company adopted this standard in 2017, with no material effect upon its financial statements. New Accounting Requirements and Disclosures In January 2016, the FASB issued ASU No. 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-01 requires that most equity investments be measured at fair value, with subsequent changes in fair value recognized in net income. The pronouncement also impacts financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. This pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and early adoption is not permitted. The Company does not believe that the adoption of this pronouncement will have a material impact on the Company’s consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, “Leases,” which requires companies that lease assets to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in its balance sheet. The pronouncement will also require additional disclosures about the amount, timing and uncertainty of cash flows arising from leases. This pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, and early adoption is permitted. The Company is currently evaluating the impact of this pronouncement on the Company's consolidated financial statements. |

CASH, CASH EQUIVALENTS AND RESTRICTED CASH | CASH, CASH EQUIVALENTS AND RESTRICTED CASH At December 31, 2017 and 2016, the Company maintained $6.2 million and $9.6 million as restricted cash. During 2017, $4.2 million was received from the Cancer Prevention and Research Institute of Texas, or “CPRIT”, and is being held in a separate account to be used for costs solely related to the CPRIT grant. Release of the CPRIT funds are subject to the terms of the grant agreement and requirements therein and require the authorization of CPRIT. The remaining $2 million of restricted cash in 2017 and the $9.6 million in 2016 is held in escrow to cover specific construction of manufacturing improvement costs related to the facility lease. The release of the escrowed funds is subject to the terms of the escrow agreement and requirements therein including approval by both the Company and the landlord based on authorized completion of certain aspects of the manufacturing improvements.

FAIR VALUE OF MEASUREMENTS AND INVESTMENT SECURITIES | FAI R VALU E O F MEASUREMENTS AND INVESTMENT SECURITIES The Company follows ASC, Topic 820, Fair Value Measurements and Disclosures , or ASC 820, for application to financial assets. ASC 820 defines fair value, provides a consistent framework for measuring fair value under GAAP and requires fair value financial statement disclosures. ASC 820 applies only to the measurement and disclosure of financial assets that are required or permitted to be measured and reported at fair value under other ASC topics (except for standards that relate to share-based payments such as ASC Topic 718, Compensation – Stock Compensation ). The valuation techniques required by ASC 820 may be based on either observable or unobservable inputs. Observable inputs reflect readily obtainable data from independent sources, and unobservable inputs reflect the Company’s market assumptions. These inputs are classified into the following hierarchy: Level 1 Inputs – quoted prices (unadjusted) in active markets for identical assets that the reporting entity has the ability to access at the measurement date; Level 2 Inputs – inputs other than quoted prices included within Level 1 that are observable for the asset, either directly or indirectly; and Level 3 Inputs – unobservable inputs for the assets. The following tables present the Company’s investment securities (including, if applicable, those classified on the Company’s balance sheet as cash equivalents) that are measured at fair value on a recurring basis as of December 31, 2017 and 2016: Fair Value Measurements at Reporting Date Using Balance at Quoted prices in active Significant other Significant unobservable (in thousands) Cash Equivalents: Money market funds 25,550 25,550 — — Total Cash Equivalents $ 25,550 $ 25,550 $ — $ — Investment Securities: U.S. government agency-backed securities $ 22,604 $ — $ 22,604 $ — Corporate debt securities 38,821 — 38,821 — Total Investment Securities $ 61,425 $ — $ 61,425 $ — Fair Value Measurements at Reporting Date Using Balance at Quoted prices in active Significant other Significant unobservable (in thousands) Cash Equivalents: Money market funds $ 23,459 $ 23,459 $ — $ — Total Cash Equivalents $ 23,459 $ 23,459 $ — $ — Investment Securities: U.S. government agency-backed securities $ 25,908 $ — $ 25,908 $ — Corporate debt securities 42,053 — 42,053 — Municipal bonds 2,671 — 2,671 — Total Investment Securities $ 70,632 $ — $ 70,632 $ — U.S. Treasury, U.S. government agency-backed securities, corporate debt securities and municipal bonds are valued based on various observable inputs such as benchmark yields, reported trades, broker/dealer quotes, benchmark securities and bids.

At December 31, 2016, the Company classified all of its available -for-sale investment securities, including those with maturities beyond one year, as current assets on the accompanying balance sheets based on the highly liquid nature of the investment securities and because these investment securities were considered available for use in current operations. In 2017, however, the Company reclassified the investment in securities with maturity dates beyond one year as non-current assets as the Company does not intend to utilize them to fund current operations. |

DEBT | DEBT Hercules Loan On March 10, 2016 (the “Hercules Closing Date”), the Company entered into a Loan and Security Agreement (the “Hercules Loan Agreement”) with Hercules Capital, Inc., Hercules Technology II, L.P., and Hercules Technology III, L.P., or collectively, “Hercules”, as a lender, under which the Company borrowed $15.0 million . The Company borrowed an additional $5.0 million and $10.0 million on September 15, 2016 and March 8, 2017, respectively. The total debt was secured by a lien covering substantially all of the assets of the Company, excluding intellectual property, but including proceeds from the sale, license, or disposition of intellectual property . The interest rate was calculated at a rate equal to the greater of either (i) 9.35% plus the prime rate as reported in The Wall Street Journal minus 3.50% , or (ii) 9.35% . The interest rate on amounts borrowed under the Loan Agreement was 9.6% at December 31, 2016; there was no debt outstanding under the Hercules Loan Agreement at December 31, 2017, as discussed below. Payments under the Loan Agreement were interest only for 18 months from the Hercules Closing Date, which was extended to 24 months upon the Company achieving certain milestones. The interest only period was to be followed by equal monthly payments of principal and interest amortized over the remaining months through the maturity date of March 1, 2020 (the “Hercules Loan Maturity Date”). In addition to any remaining principal balance and accrued interest, upon the Hercules Loan Maturity date or such earlier date specified in the Hercules Loan Agreement, a final payment became due equal to $2.1 million (the “Final Hercules Facility Charge”). The Company’s obligations under the Loan Agreement were secured by a security interest in substantially all of its assets, other than its intellectual property. Under the Hercules Loan Agreement, if the Company prepaid the loan, including interest, prior to the date that is 24 months following March 10, 2016, it would pay Hercules a prepayment charge based on a prepayment fee equal to 2.00% of the amount prepaid; if the prepayment occurred thereafter, it would pay Hercules a prepayment charge based on a prepayment fee equal to 1.00% of the amount prepaid. On December 21, 2017, the Company repaid the outstanding balance, accrued interest and Final Hercules Facility Charge totaling $32.9 million , which included a prepayment charge of $ 0.6 million with proceeds from a new loan from Oxford Finance, LLC, discussed below. The Company accounted for the transaction as a debt extinguishment and recorded a loss of $1.8 million in the year ended December 31, 2017. Oxford Loan On December 21, 2017 (the “Oxford Closing Date”), the Company entered into a loan and security agreement (the “Oxford Loan Agreement”) with Oxford Finance LLC, as the collateral agent and a lender, pursuant to which the Company borrowed $35.0 million in a single term loan (the “Oxford Loan”) on the Oxford Closing Date. As discussed above, on the Oxford Closing Date, the Company used approximately $32.9 million of the proceeds from the Oxford Loan to repay its indebtedness to Hercules. The Company’s obligations under the Oxford Loan Agreement are secured by a first priority security interest in substantially all of the Company’s current and future assets, other than its intellectual property. The Company has also agreed not to encumber its intellectual property assets, except as permitted by the Oxford Loan Agreement. The Oxford Loan matures on December 1, 2022 (the “Oxford Maturity Date”) and will be interest-only through January 31, 2020, followed by 35 equal monthly payments of principal and unpaid accrued interest. The Oxford Loan bears interest at a floating per annum rate equal to (i) 7.25% plus (ii) the greater of (a) the 30 -day U.S. Dollar LIBOR rate reported in The Wall Street Journal on the last business day of the month that immediately precedes the month in which the interest will accrue and (b) 1.25% . The interest rate on amounts borrowed under the Oxford Loan Agreement was 8.8% at December 31, 2017. The Company will be required to make a final payment of 8.70% of the principal amount of the Oxford Loan borrowed (the “Oxford Final Payment Fee”), payable on the earlier of (i) the Oxford Maturity Date, (ii) the acceleration of the Oxford Loan, or (iii) the prepayment of the Oxford Loan. The Company may prepay all, but not less than all, of the borrowed amounts, provided that the Company will be obligated to pay a prepayment fee equal to (i) 3.00% of the outstanding principal balance if prepaid on or before the first anniversary of the Closing Date, (ii) 2.00% of the outstanding principal balance, if prepaid after the first anniversary and before the second anniversary of the Closing Date, and (iii) 1.00% of the outstanding principal balance prepaid thereafter and prior to the Maturity Date (each, a “Prepayment Fee”).While any amounts are outstanding under the Oxford Loan Agreement, the Company is subject to a number of affirmative and restrictive covenants, including covenants regarding delivery of financial statements, payment of taxes, maintenance of insurance, dispositions of property, business combinations or acquisitions, incurrence of additional indebtedness and transactions with affiliates, among other customary covenants. The Company is also restricted from paying dividends or making other distributions or payments of its capital stock, subject to limited exceptions. Upon the occurrence of certain events, including but not limited to the Company’s failure to satisfy its payment obligations under the Oxford Loan Agreement, the breach of certain of its other covenants under the Oxford Loan Agreement, or the occurrence of a material adverse change, the collateral agent will have the right, among other remedies, to declare all principal and interest immediately due and payable, and the lender will have the right to receive the Oxford Final Payment Fee and, if the payment of principal and interest is due prior to the Oxford Maturity Date, a Prepayment Fee. The Company paid expenses related to the Oxford Loan Agreement of $0.1 million , which, along with the final facility charge of $3.0 million , have been recorded as deferred financing costs, which offset long-term debt on the Company's balance sheet. The deferred financing costs are being amortized over the term of the loan as interest expense. During the year ended December 31, 2017, interest expense included $0.02 million of amortized deferred financing costs. The total gross payments due under our debt arrangements are as follows: As of December 31, 2017 Year (in thousands) 2018 $ — 2019 — 2020 11,000 2021 12,000 Thereafter 15,045 Total debt $ 38,045 Less deferred financing costs (3,099 ) Less current portion — Total long-term debt $ 34,946 Management believes that the carrying value of the debt facility approximates its fair value, as the Company's debt facility bears interest at a rate that approximates prevailing market rates for instruments with similar characteristics. The fair value of the Company's debt facility is determined under Level 2 in the fair value hierarchy. |

GRANT REVENUE | GRANT REVENUE Cancer Research Grant Contract On August 9, 2017, the Company entered into a Cancer Research Grant Contract (the “CPRIT Agreement”) with CPRIT, pursuant to which CPRIT awarded a grant of approximately $16.9 million to the Company to fund development of BPX-501 for hematologic cancer (the “CPRIT Award”). The CPRIT Award is contingent upon funds being available during the term of the Agreement and subject to CPRIT’s ability to perform its obligations under the Agreement. The Company and CPRIT will retain joint ownership over any intellectual property developed under the Agreement. With respect to non-commercial use of any intellectual property developed under the CPRIT Agreement (the “CPRIT Project Results”), the Company agreed to grant to CPRIT a sublicensable, nonexclusive, irrevocable, royalty-free, perpetual worldwide license to any intellectual property of the Company that is necessary to exploit the CPRIT Project Results. The CPRIT Agreement permits the Company to license any CPRIT Project Results, subject to the Company retaining an exclusive sublicensable license to exploit the CPRIT Project Results for non-commercial purposes. The Company is obligated to make revenue-sharing payments to CPRIT with respect to net sales of any product covered by the Agreement, up to a maximum repayment of 400% of the aggregate amount paid to the Company by CPRIT under the CPRIT Agreement. The payments are determined as a percentage of net sales ranging from the low to mid-single digits, which may be reduced if the Company is required to obtain a license from a third party to sell any such product. In addition, upon meeting the foregoing limitation on revenue-sharing payments, the Company agreed to make continued revenue-sharing payments to CPRIT of less than 1% of net sales. The CPRIT Agreement will expire on February 29, 2020 unless terminated earlier by: mutual consent of the parties; CPRIT upon an event of default by the Company as specified in the CPRIT Agreement; CPRIT if allocated funds become unavailable or CPRIT is unable to obtain additional funds; or the Company in its sole discretion. During 2017, the Company received $4.2 million in advance funding from CPRIT, which was recorded as deferred revenue. As of December 31, 2017, the Company incurred expenses and accrued revenue of $0.1 million for work performed under the CPRIT grant. NIH Grant During 2013, we entered into a grant agreement with the NIH. The grant was a modular multi-year grant with funds being awarded each year based on the progress of the program being funded. Grant money is not received until expenses for the program are incurred. We have been awarded approximately $1.4 million to date. The grant expired March 31, 2017. |

Disclosure of Compensation Related Costs, Share-based Payments [Abstract] | |
SHARE-BASED COMPENSATION PLANS | SHARE-BASED COMPENSATION PLANS The Company has four share-based compensation plans, which authorize the granting of shares of common stock and options to purchase common stock to employees and directors of the Company, as well as non-employee consultants, and allows the holder of the option to purchase common stock at a stated exercise price. Options vest according to the terms of the grant, which may be immediately or based on the passage of time, generally over four years, and have a term of up to 10 years. Unexercised stock options terminate on the expiration date of the grant. The Company recognizes the share-based compensation expense over the requisite service period of the individual grantees, which generally equals the vesting period. At December 31, 2017, the Company had share-based awards outstanding under four share-based compensation plans, as follows: 2006 Stock Option Plan The 2006 Stock Option Plan (the “2006 Plan”) provided for the issuance of non-qualified stock options to employees, including officers, non-employee directors and consultants to the Company. As of December 31, 2017, there were 128,188 shares of common stock reserved for issuance pursuant to outstanding options granted under the 2006 Plan. The 2006 Plan was terminated by the Board in October 2014. 2011 Stock Option Plan The 2011 Stock Option Plan (the “2011 Plan”) provided for the issuance of incentive and non-qualified stock options to employees, including officers, non-employee directors and consultants to the Company. As of December 31, 2017, there were 1,652,834 shares of common stock reserved for issuance pursuant to outstanding options granted under the 2011 Plan. The 2011 Plan replaced the 2006 Plan. The 2011 Plan terminated upon the effectiveness of the 2014 Plan described below. 2014 Equity Incentive Plan The 2014 Equity Incentive Plan (the “2014 Plan”) became effective in December 2014, upon the closing of the IPO. The 2014 Plan provides for the issuance of equity awards, including incentive and non-qualified stock options and restricted stock awards to employees, including officers, non-employee directors and consultants to the Company or its affiliates. The 2014 Plan also provides for the grant of performance cash awards and performance-based stock awards. On June 14, 2017, the stockholders approved an amendment to the 2014 Plan to, among other things, increase the number of shares of common stock authorized for issuance under the 2014 Plan by 3,100,000 shares and eliminate the prior provision in the 2014 Plan that allowed the Company’s Board of Directors to reprice stock options without stockholder approval. The aggregate number of shares of common stock that are authorized for issuance under the 2014 Plan is 6,090,354 shares, plus any shares subject to outstanding options that were granted under the 2011 Plan or 2006 Plan that are forfeited, terminated, expired or are otherwise not issued. As of December 31, 2017, there were 3,646,113 outstanding awards, comprised of 2,875,450 options, 630,000 inducement option awards, 96,250 restricted stock units, 29,413 shares of restricted stock and 15,000 inducement restricted stock units. At December 31, 2016, there were 2,334,497 options and 58,825 shares of restricted stock outstanding. As of December 31, 2017, there were 3,095,351 shares remaining to be issued. 2014 Employee Stock Purchase Plan The 2014 Employee Stock Purchase Plan (the “ESPP”) provides for eligible Company employees, as defined by the ESPP, to be given an opportunity to purchase the Company's common stock at a discount, through payroll deductions, with stock purchases being made upon defined purchase dates. The ESPP authorizes the issuance of up to 550,000 shares of the Company's common stock to participating employees, and allows eligible employees to purchase shares of common stock at a 15% discount from the grant date fair market value. During the year ended December 31, 2017 and 2016, 34,654 and 33,629 shares were purchased under the ESPP. As of December 31, 2017, there were 460,027 shares remaining to be issued. A summary of activity within the ESPP follows: Year Ended December 31, 2017 2016 (amounts in thousands) Deductions from employees $ 276 $ 375 Share-based compensation expense recognized $ 225 $ 244 Remaining share-based compensation expense $ 264 $ 406 Proceeds received by the Company for ESPP $ 293 $ 369 Weighted-average purchase price per common share $ 8.43 $ 10.97 Number of shares purchased by employees under ESPP 34,654 33,629 Share-Based Compensation Expense The valuation of the share-based compensation awards is a significant accounting estimate that requires the use of judgment and assumptions that are likely to have a material impact on the financial statements. The fair value of option grants is determined using the Black-Scholes option-pricing model. Expected volatilities utilized in the model are based on implied volatilities from traded stocks of peer companies. Similarly, the dividend yield is based on historical experience and the estimate of future dividend yields. The risk-free interest rate is derived from the U.S. Treasury yield curve in effect at the time of grant. The expected term of the options is based on the average period the stock options are expected to remain outstanding. As the Company does not have sufficient historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior, the expected term is calculated as the midpoint between the weighted-average vesting term and the contractual expiration period also known as the simplified method. The fair values of the option grants have been estimated, with the following weighted-average assumptions: Year Ended December 31, 2017 2016 2015 Risk-free interest rate 2.06 % 1.77 % 1.71 % Volatility 72 % 72 % 74 % Expected life (years) 6.08 6.08 6.08 Expected dividend yield 0 % 0 % 0 % Share-based compensation for the years ended December 31, 2017, 2016 and 2015, are as follows: Year Ended December 31, 2017 2016 2015 (in thousands) General and administrative $ 7,128 $ 6,681 $ 4,832 Research and development 6,441 5,656 3,577 Total $ 13,569 $ 12,337 $ 8,409 Stock option activity for the years ended December 31, 2017 and 2016 is as follows: Options Outstanding Stock Options Weighted-Average Exercise Price Weighted-Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (1) (in thousands) Balance at December 31, 2015 3,628,973 $ 10.32 8.03 $ 39,021 Granted 1,159,957 $ 17.43 Exercised (190,055) $ 4.07 $ 2,448 Forfeited (66,755) $ 12.46 Balance at December 31, 2016 4,532,120 $ 12.37 7.58 $ 20,453 Granted (2) 1,504,625 $ 11.67 Exercised (344,958) $ 4.31 Forfeited (405,315) $ 16.97 Balance at December 31, 2017 5,286,472 $ 12.35 7.35 $ 7,223 Exercisable as of December 31, 2017 2,875,255 $ 11.06 6.30 $ 6,934 (1) The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying options and the estimated fair value of the common stock for the options that were in the money at December 31, 2017.

Income Tax Disclosure [Abstract] | |
INCOME TAXES | INCOME TAXES On December 22, 2017, the U.S. government enacted tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “2017 Tax Act”). The 2017 Tax Act significantly revises how U.S. taxes corporations. The Company is currently evaluating provisions of the 2017 Tax Act, which among other things, lowers the U.S. corporate income tax rate from 35% to 21% and moves toward a territorial tax system. As a result, an adjustment has been recorded to the deferred tax asset and a corresponding adjustment to the full valuation allowance. As the Company does not have all of the necessary information to analyze all income tax effects of the 2017 Tax Act, the Company will continue to make and refine calculations and estimates as additional information is obtained, which could potentially affect the provisional amounts relating to the deferred income taxes, including but not limited to deferred tax assets related to share-based compensation expenses. Where the Company has not yet been able to make reasonable estimates of the impact of certain elements, the Company has not recorded any amounts related to those elements and has continued accounting for them in accordance with ASC 740 on the basis of the tax laws in effect immediately prior to the enactment of the 2017 Tax Act. The Company expects to complete a detailed analysis no later than the fourth quarter of 2018. The Company accounts for uncertain tax positions in accordance with the provisions of ASC 740, Income Taxes. When uncertain tax positions exist, the Company recognizes the tax benefit of tax positions to the extent that the benefit will more likely than not be realized. The determination as to whether the tax benefit will more likely than not be realized is based upon the technical merits of the tax position as well as consideration of the available facts and circumstances. As of December 31, 2017, 2016 and 2015, the Company had no uncertain tax positions and no interest or penalties have been charged to the Company for the years ended December 31, 2017, 2016 and 2015. If incurred, the Company will classify any interest and penalties as a component of interest expense and operating expense, respectively. The Company is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The tax years 2005 through 2017 remain open to examination by the Internal Revenue Service. The reconciliation between federal income taxes at the statutory rate and the Company’s income tax expense for the year is as follows: December 31, 2017 2016 2015 (in thousands) Tax benefit at statutory rate $ (31,204 ) $ (23,542 ) $ (16,506 ) Stock options 860 394 12 Other (36 ) 54 (165 ) U.S. tax reform rate change 37,848 — — Stock compensation 333 — — Deferred tax valuation allowances (1,824 ) 24,872 17,920 Research and development credit (5,977 ) (1,778 ) (1,261 ) Income tax expense $ — $ — $ — Deferred income taxes reflect the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes, and the amounts used for income tax purposes. Significant components of the Company’s deferred taxes as of December 31, 2017 and 2016 are as follows: December 31, 2017 2016 (in thousands) Deferred tax assets: Net operating loss carryforward $ 46,772 $ 48,152 Stock compensation 4,900 5,146 Intangible assets 8,820 14,920 Research and development credit 10,273 4,296 Other 648 702 Total deferred tax assets 71,413 73,216 Valuation allowance (71,413 ) (73,216 ) Net deferred tax assets $ — $ — As of December 31, 2017 and 2016, the Company had gross federal income tax net operating loss (NOL) carryforwards of $222.7 million and $142.2 million , respectively, and federal research tax credits of $10.3 million and $4.3 million , respectively. The Internal Revenue Code Section 382 limits NOL and tax credit carry forwards when an ownership change of more than 50% of the value of the stock in a loss corporation occurs. Accordingly, the ability to utilize remaining NOL and tax credit carryforwards may be significantly restricted. The NOL carryforwards will expire beginning in 2025 , if not utilized. In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax asset will be realized. The ultimate realization of deferred tax assets is dependent upon the Company attaining future taxable income during periods in which those temporary differences become deductible. Due to the uncertainty surrounding the realization of the benefits of its deferred assets, including NOL carryforwards, the Company has provided a 100% valuation allowance on its deferred tax assets at December 31, 2017 and 2016. The changes in the valuation allowance were a decrease of $1.8 million and an increase of $24.9 million for the years ended December 31, 2017 and 2016, respectively. |

Accounting Policies [Abstract] | |
Use of Estimates | Use of Estimates The preparation of the financial statements in accordance with GAAP requires management to make certain estimates and judgments that affect the reported amounts of assets, liabilities, and expenses. Actual results could differ from those estimates. |
Consolidation | Consolidation All financial information presented includes the accounts of the Company and its wholly-owned subsidiaries, neither of which have had any material activity to date. All significant intercompany balances and transactions have been eliminated in consolidation. |
Revenue Recognition | Revenue Recognition The Company has not yet generated any revenue from product sales. The Company’s source of revenue in 2017, 2016 and 2015 has been from grants. When grant funds are received after costs have been incurred, the Company accrues revenue and records a grant receivable. Cash received from grants in advance of incurring qualifying costs is recorded as deferred revenue, and recognized as revenue when qualifying costs are incurred. |
Cash and Cash Equivalents | Cash and Cash Equivalents The Company considers all short-term, highly liquid investments with maturity of three months or less from the date of purchase to be cash equivalents. |
Investment Securities | Investment Securities Consistent with its investment policy, the Company invests its cash allocated to fund its short-term liquidity requirements with prominent financial institutions in bank depository accounts and institutional money market funds. The Company invests the remainder of its cash in corporate debt securities and municipal bonds rated at least A quality or equivalent, U.S. Treasury notes and bonds and U.S. and state government agency-backed securities. The Company determines the appropriate classification of investment securities based on whether they represent the investment of funds available for current operations, as defined in ASC 210-10-45-1 and ASC 210-10-45-2. The Company reevaluates its classification as of each balance sheet date. All investment securities owned are classified as available-for-sale. The cost of securities sold is based on the specific identification method. Investment securities are recorded as of each balance sheet date at fair value, with unrealized gains and, to the extent deemed temporary, unrealized losses reported as accumulated other comprehensive gain (loss), a separate component of stockholders' equity. Interest and dividend income on investment securities, accretion of discounts and amortization of premiums and realized gains and losses are included in interest income in the statements of operations and comprehensive income (loss). An investment security is considered to be impaired when a decline in fair value below its cost basis is determined to be other than temporary. The Company evaluates whether a decline in fair value of an investment security is below its cost basis is other than temporary using available evidence. In the event that the cost basis of the investment security exceeds its fair value, the Company evaluates, among other factors, the amount and duration of the period that the fair value is less than the cost basis, the financial health of and business outlook for the issuer, including industry and sector performance, and operational and financing cash flow factors, overall market conditions and trends, the Company’s intent to sell the investment security and whether it is more likely than not the Company would be required to sell the investment security before its anticipated recovery. If a decline in fair value is determined to be other than temporary, the Company records an impairment charge in the statement of operations and comprehensive loss and establishes a new cost basis in the investment. |
Property and Equipment | Property and Equipment Leasehold improvements, furniture, equipment and software are recorded at cost and are depreciated using the straight-line method over the estimated useful lives of the related assets, which range from three to five years. Leasehold improvements are amortized over the shorter of the estimated useful life or the remaining lease term. |
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets The Company reviews long-lived assets for impairment when events or changes in business conditions indicate that their carrying value may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. There were no impairment charges related to long-lived assets for the years ended December 31, 2017, 2016 and 2015. |
Debt Issuance Costs | Debt Issuance Costs Costs related to debt issuance are presented in the balance sheet as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts and are amortized using the effective interest method. Amortization of debt issuance costs are included in interest expense. |
Rent and Deferred Rent | Rent and Deferred Rent The Company recognizes rent expense for leases with increasing annual rents on a straight-line basis over the term of the lease. The amount of rent expense in excess of cash payments is classified as deferred rent. Any lease incentives received are deferred and amortized over the term of the lease. |
Fair Value of Financial Instruments | Fair Value of Financial Instruments Accounting standards include disclosure requirements around fair values used for certain financial instruments and establish a fair value hierarchy. The three-tier hierarchy prioritizes valuation inputs into three levels based on the extent to which inputs used in measuring fair value are observable in the market, as described further in Note 5. The Company believes the recorded values of its financial instruments, including cash and cash equivalents, accounts payable and accrued liabilities approximate their fair values due to the short-term nature of these instruments. |
Financial Instruments and Credit Risks | Financial Instruments and Credit Risks Financial instruments that potentially subject the Company to credit risk include cash and cash equivalents, investment securities, and accounts receivable. Cash is deposited in demand accounts in federally insured domestic institutions to minimize risk. Insurance is provided through the Federal Deposit Insurance Corporation (“FDIC”) and Security Investor Protection Corporation (“SIPC”). Although the balances in these accounts exceed the federally insured limit from time to time, the Company has not incurred losses related to these deposits. |
Equity Issuance Costs | Equity Issuance Costs Equity issuance costs represent costs paid to third parties in order to obtain equity financing. These costs have been netted against the proceeds of the equity issuances. |
Licenses and Patents | Licenses and Patents Licenses and patent costs for technologies that are utilized in research and development and have no alternative future use are expensed as incurred. Costs related to the license of patents from third parties and internally developed patents are classified as research and development expenses. Legal costs related to patent applications and maintenance are classified as general and administrative expenses. |
Clinical Trials | Clinical Trials The Company estimates its clinical trial expense accrual for a given period based on the number of patients enrolled at each site, estimated cost per patient, and the length of time each patient has been in the trial, less amounts previously billed. These accruals are recorded in accrued expenses and other current liabilities, and the related expense is recorded in research and development expense. |
Research and Development | Research and Development Research and development expenses consist of expenses incurred in performing research and development activities, including compensation and benefits for research and development employees and consultants, facilities expenses, overhead expenses, cost of laboratory supplies, manufacturing expenses, fees paid to third parties and other outside expenses. Research and development costs are expensed as incurred. Clinical trial and other development costs incurred by third parties are expensed as the contracted work is performed. The Company accrues for costs incurred as the services are being provided by monitoring the status of the clinical trial or project and the invoices received from its external service providers. The Company estimates depend on the timeliness and accuracy of the data provided by the vendors regarding the status of each project and total project spending. The Company adjusts its accrual as actual costs become known. Where contingent milestone payments are due to third parties under research and development arrangements, the milestone payment obligations are expensed when the milestone events are achieved. |
Collaboration Agreements | Collaboration Agreements The Company enters into collaboration agreements that include varying arrangements regarding which parties perform and bear the costs of research and development activities. The Company may share the costs of research and development activities with a collaborator, or the Company may be reimbursed for all or a significant portion of the costs of the Company's research and development activities. The Company records its internal and third-party development costs associated with these collaborations as research and development expenses. When the Company is entitled to reimbursement of all or a portion of the research and development expenses that it incurs under a collaboration, the Company records those reimbursable amounts as a deduction to the research and development expenses. If the collaboration is a cost-sharing arrangement in which both the Company and its collaborator perform development work and share costs, the Company also recognizes, as research and development expenses in the period when its collaborator incurs development expenses, the portion of the collaborator's development expenses that the Company is obligated to reimburse. |
Contract Manufacturing Services | Contract Manufacturing Services Contract manufacturing services are expensed as incurred. Prepaid expenses are capitalized and amortized as services are performed. |
Share-Based Compensation | Share-Based Compensation The Company accounts for its share-based compensation in accordance with ASC 718, Compensation — Stock Compensation , which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees and directors to be recognized in the financial statements, based on their fair value. The Company measures share-based compensation to consultants in accordance with ASC 505-50, Equity-Based Payments to Non-Employees , and recognizes the fair value of the award over the period the services are rendered. The Company uses the Black-Scholes option-pricing model to estimate the fair value of stock option awards. The fair value is recognized as expense, net of estimated forfeitures, over the requisite service period, which is generally the vesting period of the respective award on a straight-line basis. |
Income Taxes | Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. This method also requires the recognition of future tax benefits such as net operating loss and tax credit carry forwards, to the extent that realization of such benefits is more likely than not. A valuation allowance is recorded when the realization of future tax benefits is uncertain. The Company records a valuation allowance for the full amount of deferred tax assets, which would otherwise be recorded for tax benefits relating to the operating loss and tax credit carryforwards, as realization of such deferred tax assets cannot be determined to be more likely than not. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the statement of operations in the period that includes the enactment date. On December 22, 2017, the U.S. government enacted tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “2017 Tax Act”). The 2017 Tax Act significantly revises how U.S. taxes corporations. The Company is currently evaluating provisions of the 2017 Tax Act, which among other things, lowers the U. S. corporate income tax rate from 35% to 21% and moves toward a territorial tax system. As a result, an adjustment has been recorded to the deferred tax asset and a corresponding adjustment to the full valuation allowance. As the Company does not have all of the necessary information to analyze all income tax effects of the 2017 Tax Act, the Company will continue to evaluate tax reform and adjust the provisional amounts related to deferred income tax as additional information is obtained. The Company expects to complete a detailed analysis no later than the fourth quarter of 2018. The Company accounts for uncertain tax positions in accordance with the provisions of ASC 740, Income Taxes . When uncertain tax positions exist, the Company recognizes the tax benefit of tax positions to the extent that the benefit will more likely than not be realized. The determination as to whether the tax benefit will more likely than not be realized is based upon the technical merits of the tax position as well as consideration of the available facts and circumstances. As of December 31, 2017, 2016 and 2015, the Company had no uncertain tax positions and no interest or penalties have been charged to the Company for the years ended December 31, 2017, 2016 and 2015. If incurred, the Company will classify any interest and penalties as a component of interest expense and operating expense, respectively. The Company is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The tax years 2005 through 2017 remain open to examination by the Internal Revenue Service. |
Comprehensive Loss | Comprehensive Loss Comprehensive income (loss) is defined as the change in equity of a business enterprise during a period, from transactions, and other events and circumstances from non-owner sources. Components of comprehensive income (loss) includes, among other items, unrealized gains and losses on the changes in fair value of investments. These components are added, net of their related tax effect, to the reported net income (loss) to arrive at comprehensive income (loss). The components of accumulated other comprehensive loss at December 31, 2017 and 2016, on the Company’s balance sheet was comprised of the net unrealized holding losses on the Company’s investment securities. See Note 5 for further detail of the unrealized holding gains and losses on the Company’s investment securities. |
Net Loss and Net Loss per Share of Common Stock Attributable to Common Stockholders | Net Loss and Net Loss per Share of Common Stock Attributable to Common Stockholders Basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of share of common stock outstanding during the period without consideration for common stock equivalents. |
New Accounting Standards, Requirements and Disclosures | Application of New Accounting Standards During 2017, the Company adopted ASU No. 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” , which is intended to simplify the financial reporting of the income tax impacts of share-based compensation arrangements. The classification guidance under ASU No. 2016-09 requires the recognition of excess tax benefits from share-based compensation arrangements as a discrete item within income tax benefit rather than additional paid-in capital and the classification guidance requiring presentation of excess tax benefits from share-based compensation arrangements as an operating activity on the statement of cash flows, rather than as a financing activity. The adoption of ASU No 2016-09 had no immediate impact on the Company's financial statements and related disclosures because the Company does not currently recognize a tax benefit related to share-based compensation expense as it maintains net operating loss carryforwards and has established a valuation allowance against the entire net deferred tax asset as of December 31, 2017. Further, the Company has elected to continue to estimate the number of stock-based awards expected to vest, as permitted by ASU 2016-09, rather than electing to account for forfeitures as they occur. In August 2016, the FASB issued ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments,” which provides guidance on the classification of certain cash receipts and payments in the statement of cash flows. The pronouncement is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods. Earlier application is permitted in any interim or annual period. The Company adopted this standard in 2017, with no material effect upon its financial statements. New Accounting Requirements and Disclosures In January 2016, the FASB issued ASU No. 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-01 requires that most equity investments be measured at fair value, with subsequent changes in fair value recognized in net income. The pronouncement also impacts financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. This pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and early adoption is not permitted. The Company does not believe that the adoption of this pronouncement will have a material impact on the Company’s consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, “Leases,” which requires companies that lease assets to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in its balance sheet. The pronouncement will also require additional disclosures about the amount, timing and uncertainty of cash flows arising from leases. This pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, and early adoption is permitted. The Company is currently evaluating the impact of this pronouncement on the Company's consolidated financial statements. |
