The Company’s headquarters and research facility are located in Hayward, California. The Company’s activities are subject to significant risks and uncertainties, including the need for additional capital. The Company has not yet commenced any revenue-generating operations, does not have any cash flows from operations, and will need to raise additional capital to finance its operations. However, there can be no assurances that the Company will be able to obtain additional financing on acceptable terms and in the amounts necessary to fully fund its operating requirements.

| Summary Of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Basis of Presentation In the opinion of the Company’s management, the accompanying unaudited condensed consolidated financial statements (“Financial Statements”) have been prepared on a basis consistent with the Company’s December 31, 2017 audited Consolidated Financial Statements and include all adjustments, consisting of only normal recurring adjustments, necessary to fairly state the information set forth herein. The Financial Statements have been prepared in accordance with the applicable rules and regulations of the Securities and Exchange Commission and, as permitted by such rules and regulations, omit certain information and footnote disclosures necessary to present the financial statements in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). The condensed consolidated balance sheet as of December 31, 2017 was derived from the audited consolidated financial statements as of that date, but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These Financial Statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. The results of operations for the three and six-month periods ended June 30, 2018 are not necessarily indicative of the results to be expected for the entire year or any future periods. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates and assumptions that affect the amounts reported in the Financial Statements and accompanying notes to the Financial Statements. Estimates include, but are not limited to, the valuation of cash equivalents and investments, the valuation and recognition of share-based compensation and the useful lives assigned to long-lived assets. The Company evaluates its estimates and assumptions based on historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. Actual results could differ materially from these estimates. Significant Accounting Policies There have been no material changes to the Company’s significant accounting policies during the three and six-month period ended June 30, 2018, as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. Principles of Consolidation The accompanying consolidated financial statements include the financial statements of Pulse and its wholly-owned subsidiaries. Intercompany balances and transactions, if any, have been eliminated in consolidation. Net Loss per Share The Company calculates basic net loss per share by dividing net loss by the weighted average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potential dilutive common stock equivalents outstanding during the period. For purposes of this calculation, options to purchase common stock and common stock warrants are considered common stock equivalents. Potential common shares that have an anti-dilutive effect (i.e., those that increase income per share or decrease loss per share) are excluded from the calculation of diluted net loss per share. Basic and diluted net loss per common share is the same for all periods presented because all warrants, stock options and restricted stock units outstanding are anti-dilutive. The following outstanding stock options, warrants and restricted stock units were excluded from the computation of diluted net loss per share for the periods presented because including them would have had an anti-dilutive effect:
Certain items in prior period financial statements have been reclassified to conform to the presentation in the current period financial statements. Such reclassifications did not impact the Company's previously reported net loss or financial position. Recent Accounting Pronouncements During February 2016, the FASB issued ASU No. 2016-02, Leases, which amends the existing accounting standards for leases. The new standard requires lessees to record a right-of-use asset and a corresponding lease liability on the balance sheet (with the exception of short-term leases). For lessees, leases will continue to be classified as either operating or financing in the income statement. This ASU becomes effective for the Company in the first quarter of fiscal year 2019 and early adoption is permitted. This ASU is required to be applied with a modified retrospective approach and requires application of the new standard at the beginning of the earliest comparative period presented. The Company generally does not finance purchases of equipment or other capital assets, but does lease its facilities. While the Company is continuing to assess all potential impacts of this standard, it expects that most of its lease commitments will be subject to the updated standard and recognized as lease liabilities and right-of-use assets upon adoption.

| Fair Value Of Financial Instruments | 3. Fair Value of Financial Instruments The authoritative guidance with respect to fair value established a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three levels, and requires that assets and liabilities carried at fair value be classified and disclosed in one of three categories, as presented below. Level 1 - Observable inputs such as quoted prices in active markets for an identical asset or liability that the Company has the ability to access as of the measurement date. Financial assets and liabilities utilizing Level 1 inputs include money market funds. Level 2 - Inputs, other than quoted prices included within Level 1, which are directly observable for the asset or liability or indirectly observable through corroboration with observable market data. Financial assets and liabilities utilizing Level 2 inputs include commercial paper, corporate bonds, and asset-backed securities. Level 3 - Unobservable inputs for which there is little or no market data for the asset or liability which requires the reporting entity to develop its own assumptions. The Company did not classify any of its investments within Level 3 of the fair value hierarchy. The following table sets forth the fair value of the Company’s financial assets measured on a recurring basis as of June 30, 2018 and December 31, 2017, respectively (in thousands):
The Company did not have any financial liabilities measured on a recurring basis as of June 30, 2018 or December 31, 2017. During the six-month period ended June 30, 2018, there were no transfers between Level 1, Level 2 or Level 3 assets or liabilities reported at fair value on a recurring basis and the valuation techniques used did not change compared to the Company’s established practice.

| Stockholders' Equity And Stock-Based Compensation | 8. Stockholders’ Equity and Stock-Based Compensation Private Placements In February 2017, the Company entered into a securities purchase agreement, pursuant to which the Company, in a private placement, issued and sold an aggregate of 819,673 shares of the Company’s common stock, par value $0.001 per share, at a price per share of $6.10, for net proceeds of approximately $5.0 million. In September 2017, the Company entered into a securities purchase agreement with an existing investor, pursuant to which the Company, in a private placement, issued and sold an aggregate of 2,000,000 shares of the Company’s common stock, par value $0.001 per share, at a price per share of $15.02, for net proceeds of approximately $29.9 million. Warrants In connection with a private placement offering of the Company’s shares of common stock in 2014, the Company issued warrants as compensation to the placement agent to purchase a total of 299,625 shares of its common stock at a price of $2.67 per share (the “Private Placement Warrants”). The Private Placement Warrants are exercisable for period of seven years. As of June 30, 2018, there were a total of 91,876 of Private Placement Warrants outstanding. In connection with the closing of the Company’s initial public offering in 2016, the Company issued warrants as compensation to its underwriters, as representatives of the underwriters of its initial public offering to purchase a total of 574,985 shares of its common stock at a price of $5.00 per share (“the IPO Warrants”). The IPO Warrants are exercisable for a period of five years. As of June 30, 2018, there were a total of 157,833 of the IPO Warrants outstanding. Equity Plans 2017 Equity Incentive Plan and 2017 Inducement Equity Incentive Plan The Board of Directors of the Company (the “Board”) previously adopted, and the Company’s stockholders approved, the Company’s 2017 Equity Incentive Plan (the “2017 Plan”). The 2017 Plan has a 10-year term, and provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, performance units, and performance shares to employees, directors and consultants of the Company and any parent or subsidiary of the Company, as the Compensation Committee of the Board may determine. Subject to an annual evergreen increase and adjustment in the case of certain capitalization events, the Company initially reserved 1,500,000 shares of the Company’s common stock for issuance pursuant to awards under the 2017 Plan. In addition, shares remaining available under the Company’s 2015 Equity Incentive Plan, as amended (the “2015 Plan”), and shares reserved but not issued pursuant to outstanding equity awards that expire or terminate without being exercised or that are forfeited or repurchased by the Company will be added to the shares of common stock available for issuance under the 2017 Plan. The 2017 Plan is administered by the Board’s Compensation Committee. Effective January 1, 2018, the number of shares of common stock available under the 2017 Plan increased by 672,915 shares pursuant to the evergreen provision of the 2017 Plan. Pursuant to the 2017 Plan, the 2018 share increase is determined based on the least of (i) 1,200,000 shares, (ii) 4% of the Company’s common stock outstanding at December 31 of the immediately preceding year, or (iii) such number of shares as determined by the Board. As of June 30, 2018, 659,061 shares of common stock remained available for issuance under the 2017 Plan. During November 2017, the Board adopted the 2017 Inducement Equity Incentive Plan (the “Inducement Plan”) and reserved 1,000,000 shares of the Company’s common stock for issuance pursuant to equity awards granted under the Inducement Plan. The Inducement Plan was adopted without stockholder approval. The Inducement Plan has a 10-year term, and provides for the grant of equity-based awards, including nonstatutory stock options, restricted stock units, restricted stock, stock appreciation rights, performance shares and performance units, and its terms are substantially similar to the 2017 Plan, including with respect to treatment of equity awards in the event of a “merger” or “change in control” as defined under the Inducement Plan. Options issued under the Inducement Plan may have a term up to ten years and have variable vesting provisions. New hire grants generally vest 25% upon the first anniversary of the grant and 1/48th monthly thereafter, over the subsequent 36 months. Equity-based awards issued under the Inducement Plan are only issuable to individuals not previously engaged as employees or non-employee directors of the Company prior to the Inducement Plan’s adoption date. As of June 30, 2018, 425,000 shares of common stock remained available for issuance under the Inducement Plan. 2017 Employee Stock Purchase Plan The Board previously adopted and the stockholders approved the Company’s 2017 Employee Stock Purchase Plan (the “2017 ESPP”). The 2017 ESPP is a broad-based plan that provides employees of the Company and its designated affiliates with the opportunity to become stockholders through periodic payroll deductions that are applied towards the purchase of Company common shares at a discount from the then-current market price. Subject to adjustment in the case of certain capitalization events, a total of 250,000 common shares of the Company were available for purchase at adoption of the 2017 ESPP. Effective January 1, 2018, the number of shares of common stock available under the 2017 ESPP increased by 252,343 shares pursuant to the evergreen provision of the 2017 ESPP. Pursuant to the 2017 ESPP, the annual share increase pursuant to the evergreen provision is determined based on the least of (i) 450,000 shares, (ii) 1.5% of the Company’s common stock outstanding at December 31 of the immediately preceding year, or (iii) such number of shares as determined by the Board. During the six-month period ended June 30, 2018, the Company issued 12,239 shares of common stock under the 2017 ESPP. As of June 30, 2018, 490,104 shares of common stock remained available for issuance under the 2017 ESPP. A summary of stock option activity under the 2015 Plan, 2017 Plan and Inducement Plan for the six-months ended June 30, 2018 is presented below:
The table above excludes 192,500 performance stock options granted during the six-month period ended June 30, 2018 for which the performance criteria had not been established as of June 30, 2018. Stock-based Compensation Total stock-based compensation expense consisted of the following (in thousands):
The Company estimated the fair value of employee stock options on the grant date using the Black-Scholes option pricing model. The estimated fair value of employee stock options is amortized on a straight-line basis over the requisite service period of the awards. The Company reviews, and when deemed appropriate, updates the assumptions used on a periodic basis. Due to the limited trading history of the Company’s common stock, the Company utilizes a portfolio of comparable companies to estimate volatility. The fair value of employee stock options was estimated using the following weighted-average assumptions:
The Company estimated the fair value of ESPP on the grant date using the Black-Scholes option pricing model. The estimated fair value of ESPP is amortized on a straight-line basis over the requisite service period of the awards. The Company reviews, and when deemed appropriate, updates the assumptions used on a periodic basis. The Company utilizes its estimated volatility in the Black-Scholes option pricing model to determine the fair value of ESPP. The fair value of ESPP was estimated using the following weighted-average assumptions:
The fair value of restricted stock unit (“RSUs”) awards is determined based on the number of units granted and the closing price of the Company’s common stock as of the grant date. The estimated fair value of RSUs is recognized on a straight-line basis over the requisite service period. In the three-month period ended June 30, 2017, the Company granted 160,974 RSUs, all of which vested, pursuant to which no shares were issued, during June 2018. Additional paid in capital was reduced by $0.1 million for tax payments related to shares withheld in connection with the vesting of the RSUs. The stock-based compensation expense related to these RSUs was approximately $0.9 million and $2.1 million and for the three and six-month periods ended June 30, 2018, respectively. During the three-month period ended September 30, 2017, the Company granted 68,800 RSUs to certain employees which vest 50% on June 1, 2019 with the remaining 50% vesting on June 1, 2021. In the event of a change in control, these RSUs vest 100%. The stock-based compensation expense related to these RSUs was approximately $0.1 million and $0.2 million for the three-month and six-month periods ended June 30, 2018, respectively.

| Research Grants And Agreements | 9. Research Grants and Agreements Sponsored Research Agreement The Company entered into a Sponsored Research Agreement (“SRA”) with ODURF during 2014 pursuant to which the Company may annually sponsor research activities performed by ODURF’s Frank Reidy Center. ODURF is compensated by the Company for its conduct of each study in accordance with the budget and payment terms set forth in the applicable task order. During the second quarters of 2017 and 2016, the Company agreed to sponsor $0.7 million and $1.0 million, respectively, in research during the subsequent 12-month period to be funded through monthly payments made upon ODURF certifying, to the Company’s reasonable satisfaction, that ODURF has met its obligations pursuant to the specified task order and statement of work. The principal investigator may transfer funds with the budget as needed without the Company’s approval so long as the obligations of ODURF under the task order and statement of work remain unchanged and unimpaired. As of June 30, 2018, no amount remained payable under this agreement. In addition, during 2017, the Company agreed to provide $0.3 million in research funding to researchers affiliated with ODURF and Eastern Virginia Medical School matching funds made available to those researchers by the Virginia Biosciences Health Research Corporation. The Company’s sponsorship affords access to certain intellectual property, if any, developed during the project. As of June 30, 2018, $75,000 remained available under this agreement.

| Commitments And Contingencies | 10. Commitments and Contingencies Operating Leases As of June 30, 2018, the Company leases approximately 15,700 square feet for its corporate headquarters in Hayward, California (the “Premises”). The lease commenced on July 1, 2017 and expires in August 2022, with an option to extend the lease term for an additional five years. Under the terms of the lease agreement, the landlord provided an allowance for tenant improvements in the amount of $2.1 million, which was recorded as deferred rent at the inception of the lease term. Rent expense associated with future minimum lease payments is reduced by amortization of the tenant improvement allowance over the life of the lease. An offsetting amount was recorded as leasehold improvements at the inception of the lease term. Leasehold improvements are depreciated over the lease term. Future minimum lease payments under non-cancelable operating leases as of June 30, 2018 are as follows (in thousands):
The Company leased approximately 4,300 square feet of corporate offices and research facilities in Burlingame, California, at a monthly cost of approximately $21,000. This lease expired on June 30, 2017. During the three-month periods ended June 30, 2018 and 2017, rent expense, including common area maintenance charges, was approximately $69,000 and $74,000, respectively. During the six-month periods ended June 30, 2018 and 2017, rent expense, including common area maintenance charges, was approximately $0.1 million, and $0.1 million, respectively. Indemnification The Company and certain directors have received subpoenas from the Securities and Exchange Commission requesting documents and other information in connection with an investigation into trading in the Company’s stock in advance of the Company’s September 2017 private placement equity financing. The Company is cooperating with the investigation. The Company maintains indemnification agreements with its directors and officers that may require the Company to indemnify them against liabilities that arise by reason of their status or service as directors or officers, except as prohibited by applicable law. At this time, the Company is unable to estimate a possible loss, if any, associated with the matter described above. From time to time, the Company may be involved in a variety of claims, lawsuits, investigations and proceedings relating to securities laws, product liability, patent infringement, contract disputes and other matters relating to various claims that arise in the normal course of our business in addition to governmental and other regulatory investigations and proceedings. In addition, third parties may, from time to time, assert claims against the Company in the form of letters and other communications. The Company currently believes that these ordinary course matters will not have a material adverse effect on our business; however, the results of litigation and claims are inherently unpredictable. Regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources and other factors.

| Summary Of Significant Accounting Policies [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Basis Of Presentation | Basis of Presentation In the opinion of the Company’s management, the accompanying unaudited condensed consolidated financial statements (“Financial Statements”) have been prepared on a basis consistent with the Company’s December 31, 2017 audited Consolidated Financial Statements and include all adjustments, consisting of only normal recurring adjustments, necessary to fairly state the information set forth herein. The Financial Statements have been prepared in accordance with the applicable rules and regulations of the Securities and Exchange Commission and, as permitted by such rules and regulations, omit certain information and footnote disclosures necessary to present the financial statements in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). The condensed consolidated balance sheet as of December 31, 2017 was derived from the audited consolidated financial statements as of that date, but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These Financial Statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. The results of operations for the three and six-month periods ended June 30, 2018 are not necessarily indicative of the results to be expected for the entire year or any future periods.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Use Of Estimates | Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates and assumptions that affect the amounts reported in the Financial Statements and accompanying notes to the Financial Statements. Estimates include, but are not limited to, the valuation of cash equivalents and investments, the valuation and recognition of share-based compensation and the useful lives assigned to long-lived assets. The Company evaluates its estimates and assumptions based on historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. Actual results could differ materially from these estimates.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Significant Accounting Policies | Significant Accounting Policies There have been no material changes to the Company’s significant accounting policies during the three and six-month period ended June 30, 2018, as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Principles of Consolidation | Principles of Consolidation The accompanying consolidated financial statements include the financial statements of Pulse and its wholly-owned subsidiaries. Intercompany balances and transactions, if any, have been eliminated in consolidation.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Net Loss Per Share | Net Loss per Share The Company calculates basic net loss per share by dividing net loss by the weighted average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potential dilutive common stock equivalents outstanding during the period. For purposes of this calculation, options to purchase common stock and common stock warrants are considered common stock equivalents. Potential common shares that have an anti-dilutive effect (i.e., those that increase income per share or decrease loss per share) are excluded from the calculation of diluted net loss per share. Basic and diluted net loss per common share is the same for all periods presented because all warrants, stock options and restricted stock units outstanding are anti-dilutive. The following outstanding stock options, warrants and restricted stock units were excluded from the computation of diluted net loss per share for the periods presented because including them would have had an anti-dilutive effect:
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Reclassifications | Reclassifications Certain items in prior period financial statements have been reclassified to conform to the presentation in the current period financial statements. Such reclassifications did not impact the Company's previously reported net loss or financial position.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Recent Accounting Pronouncements | Recent Accounting Pronouncements During February 2016, the FASB issued ASU No. 2016-02, Leases, which amends the existing accounting standards for leases. The new standard requires lessees to record a right-of-use asset and a corresponding lease liability on the balance sheet (with the exception of short-term leases). For lessees, leases will continue to be classified as either operating or financing in the income statement. This ASU becomes effective for the Company in the first quarter of fiscal year 2019 and early adoption is permitted. This ASU is required to be applied with a modified retrospective approach and requires application of the new standard at the beginning of the earliest comparative period presented. The Company generally does not finance purchases of equipment or other capital assets, but does lease its facilities. While the Company is continuing to assess all potential impacts of this standard, it expects that most of its lease commitments will be subject to the updated standard and recognized as lease liabilities and right-of-use assets upon adoption.
