Business Overview [Abstract]
Business Overview	1. Immunomedics is a clinical-stage biopharmaceutical company that develops monoclonal antibody-based products for the targeted treatment of cancer, autoimmune and other serious diseases. The Company has continued to transition its focus away from the development and commercialization of diagnostic imaging products in order to accelerate the development of its therapeutic product candidates, although the Company still manufactures and commercializes its LeukoScan ® product in territories where regulatory approvals have previously been granted in Europe, Canada and in other markets outside the U.S. LeukoScan ® is indicated for diagnostic imaging for determining the location and extent of infection and inflammation in bone of patients with suspected osteomyelitis, including patients with diabetic foot ulcers. The Company has two foreign subsidiaries, Immunomedics B.V. in the Netherlands and Immunomedics GmbH in Rodermark, Germany, that assist the Company in managing sales efforts and coordinating clinical trials in Europe. In addition, included in the accompanying condensed financial statements is the majority-owned U.S. subsidiary, IBC Pharmaceuticals, Inc. (“IBC”), which works on the development of novel cancer radiotherapeutics using patented pre-targeting technologies with proprietary, bispecific antibodies. The accompanying unaudited condensed consolidated financial statements of Immunomedics, which incorporate our subsidiaries, have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), for interim financial information and the instructions to the Quarterly Report on Form 10‑Q and Regulation S‑X. Accordingly, the statements do not include all of the information and footnotes required by GAAP for complete annual financial statements. With respect to the financial information for the interim periods included in this Quarterly Report on Form 10-Q, which is unaudited, management believes that all adjustments (consisting of normal recurring accruals), considered necessary for a fair presentation of the results for such interim periods have been included. Operating results for the three-month period ended September 30, 2016 are not necessarily indicative of the results that may be expected for the full fiscal year ending June 30, 2017, or any other period. Immunomedics is subject to significant risks and uncertainties, including, without limitation, the risk that the Company may be unable to successfully obtain financing for product development; the Company’s inability to further identify, develop and achieve commercial success for new products and technologies; the possibility of delays in the research and development necessary to select drug development candidates and delays in clinical trials; the risk that clinical trials may not result in marketable products; the risk that the Company or its’ collaborators may be unable to secure regulatory approval of and market its drug candidates; the Company’s dependence upon pharmaceutical and biotechnology collaborations; the levels and timing of payments under the Company’s collaborative agreements, if any; uncertainties about the Company’s ability to obtain new corporate collaborations and acquire new technologies on satisfactory terms, if at all; the development or regulatory approval of competing products; the Company’s ability to protect its proprietary technologies; patent-infringement claims; and risks of new, changing and competitive technologies and regulations in the United States and internationally. Since its inception in 1982, Immunomedics’ principal sources of funds have been the private and public sale of equity and debt securities, and revenues from licensing agreements, including up-front and milestone payments, funding of development programs, and other forms of funding from collaborations. As of September 30, 2016 the Company had $33.0 million in cash, cash equivalents and marketable securities. On October 12, 2016, the Company received net proceeds of approximately $28.5 million from the sale of common stock and warrants to purchase common stock. During fiscal 2017, the Company plans to continue its Phase 2 clinical trials of sacituzumab govitecan (IMMU-132) in patients with metastatic triple negative breast cancer (TNBC), metastatic non-small-cell lung cancer (NSCLC), small-cell lung cancer (SCLC), and metastatic urothelial cancers. The Company also plans to continue, without interruption, the preparation and initiation of the Phase 3 confirmatory clinical trial in TNBC, and the large-scale manufacture of IMMU-132. These activities are necessary to support the planned submission of a BLA to FDA for accelerated approval of IMMU-132 in metastatic triple-negative breast cancer. The Company anticipates that it can also continue its other operations and research and development programs at a reduced spending level. Based on the Company’s cash flow projections, it believes its cash balance as of September 30, 2016, in addition to the approximately $28.5 million in net proceeds the Company received from the sale of stock and warrants in October 2016, is sufficient to continue its planned operations and research and development programs, as described above, for at least the next twelve months. The Company will require additional funding to complete its clinical trials currently underway or planned, continue research and new development programs, and continue operations. The Company continues to pursue potential strategic licensing or collaboration agreements as a possible source of financing to fund its business plan. These business arrangements may be with new or existing partners and may include the Company’s clinical development programs as well as any of its intellectual property estate. Other potential sources of funding include equity and potential debt financing. Until the Company can generate significant cash through strategic licensing or collaboration agreements, it expects to continue to fund its operations with its current financial resources. These financial resources may not be adequate to sustain the Company’s operations. Consequently, if the Company cannot obtain sufficient funding through strategic licensing or collaborations, it could be required to finance future cash needs through the sale of additional equity and/or debt securities in capital markets. However, there can be no assurance that the Company will be able to raise the additional capital needed to complete its pipeline of research and development programs on commercially acceptable terms, if at all. The capital markets have experienced volatility in recent years, which has resulted in uncertainty with respect to availability of capital and hence the timing to meet an entity’s liquidity needs. The Company’s existing debt may also negatively impact the Company’s ability to raise additional capital. If the Company is unable to raise capital on acceptable terms, its ability to continue its business would be materially and adversely affected. Having insufficient funds may require the Company to further delay, scale-back, or eliminate some or all of its programs, or renegotiate less favorable terms than it would otherwise choose. Failure to obtain adequate financing also may adversely affect its ability to operate as a going concern.

Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. These unaudited condensed consolidated interim financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended June 30, 2016. The Company adheres to the same accounting policies in preparation of its interim financial statements. Principles of Consolidation and Presentation The condensed consolidated financial statements include the accounts of Immunomedics and its subsidiaries. Noncontrolling interests in consolidated subsidiaries in the condensed consolidated balance sheets represent minority stockholders’ proportionate share of the deficit in such subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Financial Instruments The carrying amounts of cash and cash equivalents, other current assets and current liabilities approximate fair value due to the short-term maturity of these instruments. The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Marketable Securities Marketable securities, all of which are available-for-sale, consists of corporate debt securities, U.S. bonds, U.S. sponsored agencies and municipal bonds. Corporate debt securities include Eurodollar issues of U.S. corporations, and U.S. dollar denominated issues of foreign corporations. Marketable securities are carried at fair value, with unrealized gains and losses, net of related income taxes, reported as accumulated other comprehensive loss, except for losses from impairments which are determined to be other-than-temporary. Realized gains and losses, and declines in value judged to be other-than-temporary on available-for-sale securities are included in the determination of net loss and are included in interest and other income (net), at which time the average cost basis of these securities are adjusted to fair value. Fair values are based on quoted market prices at the reporting date. Interest and dividends on available-for-sale securities are included in interest and other income (net). Inventory Inventory, which consists of raw materials, work-in-process and the finished product of LeukoScan ® , is stated at the lower of cost (which approximates first-in, first-out) or market, and includes materials, labor and manufacturing overhead. Revenue Recognition The Company has accounted for revenue arrangements that include multiple deliverables as a separate unit of accounting if both of the following criteria are met: a) the delivered item has value to the customer on a standalone basis, and b) if the right of return exists, delivery of the undelivered items is considered probable and substantially in the control of the vendor. If these criteria are not met, the revenue elements must be considered a single unit of accounting for purposes of revenue recognition. The Company allocates revenue consideration, excluding contingent consideration, based on the relative selling prices of the separate units of accounting contained within an arrangement containing multiple deliverables. Relative selling prices are determined using vendor specific objective evidence, if it exists; otherwise third-party evidence or the Company’s best estimate of selling price is used for each deliverable. Payments received under contracts to fund certain research activities are recognized as revenue in the period in which the research activities are performed. Payments received in advance that are related to future performance are deferred and recognized as revenue when the research projects are performed. Upfront nonrefundable fees associated with license and development agreements where the Company has continuing involvement in the agreement are recorded as deferred revenue and recognized over the estimated service period. The Company estimates the period of continuing involvement based on the best evidential matter available at each reporting period. If the estimated service period is subsequently modified, the period over which the upfront fee is recognized is modified accordingly on a prospective basis. In order to determine the revenue recognition for contingent milestones, the Company evaluates the contingent milestones using the criteria as provided by the Financial Accounting Standards Boards (“FASB”) guidance on the milestone method of revenue recognition, as explained in ASU 2010-17, “ Milestone Method of Revenue Recognition,” at the inception of a collaboration agreement. The criteria requires that (i) the Company determines if the milestone is commensurate with either its performance to achieve the milestone or the enhancement of value resulting from the Company’s activities to achieve the milestone, (ii) the milestone be related to past performance, and (iii) the milestone be reasonable relative to all deliverable and payment terms of the collaboration arrangement. If these criteria are met then the contingent milestones can be considered as substantive milestones and will be recognized as revenue in the period that the milestone is achieved. Royalties are recognized as earned in accordance with the terms of various research and collaboration agreements. Revenue from the sale of diagnostic products is recorded when there is persuasive evidence that an arrangement exists, delivery has occurred, the price is fixed and determinable or collectability is reasonably assured. Allowances, if any, are established for uncollectible amounts, estimated product returns and discounts. Since allowances are recorded based on management’s estimates, actual amounts may be different in the future. Research and Development Costs Research and development costs are expensed as incurred. Costs incurred for clinical trials for patients and investigators are expensed as services are performed in accordance with the agreements in place with the institutions. Reimbursement of Research & Development Costs Research and development costs that are reimbursable under collaboration agreements are included as a reduction of research and development expenses. The Company records these reimbursements as a reduction of research and development expenses as the Company’s partner in the collaboration agreement has the financial risks and responsibility for conducting these research and development activities. Stock-Based Compensation The Company utilizes stock-based compensation in the form of stock options, stock appreciation rights, stock awards, stock unit awards, performance shares, cash-based performance units and other stock-based awards, each of which may be granted separately or in tandem with other awards. The grant-date fair value of stock awards is based upon the underlying price of the stock on the date of grant. The grant-date fair value of stock option awards must be determined using an option pricing model. Option pricing models require the use of estimates and assumptions as to (a) the expected term of the option, (b) the expected volatility of the price of the underlying stock and (c) the risk-free interest rate for the expected term of the option. The Company uses the Black-Scholes-Merton option pricing formula for determining the grant-date fair value of such awards. The expected term of the option is based upon the contractual term and expected employee exercise and expected post-vesting employment termination behavior. The expected volatility of the price of the underlying stock is based upon the historical volatility of the Company’s stock computed over a period of time equal to the expected term of the option. The risk free interest rate is based upon the implied yields currently available from the U.S. Treasury yield curve in effect at the time of the grant. Pre-vesting forfeiture rates are estimated based upon past voluntary termination behavior and past option forfeitures. The following table sets forth the weighted-average assumptions used to calculate the fair value of options granted for the three-month periods ended September 30, 2016 and 2015: Three Months Ended September 30, 2016 2015 Expected dividend yield 0% 0% Expected option term (years) 5.05 5.03 Expected stock price volatility 62% 56% Risk-free interest rate 1.16% - 1.21% 1.51% - 1.61% The Company uses historical data to estimate forfeitures. The expected term of options granted represents the period of time that options granted are expected to be outstanding. Expected stock price volatility was calculated based on the Company’s daily stock trading history. The risk-free rate for periods within the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Changes in any of these assumptions could impact, potentially materially, the amount of expense recorded in future periods related to stock-based awards. Income Taxes The Company uses the asset and liability method to account for income taxes, including the recognition of deferred tax assets and deferred tax liabilities for the anticipated future tax consequences attributable to differences between financial statement amounts and their respective tax bases. The Company reviews its deferred tax assets for recovery. A valuation allowance is established when the Company believes that it is more likely than not that its deferred tax assets will not be realized. Changes in valuation allowances from period to period are included in the Company’s tax provision in the period of change. The Company has recorded a full valuation allowance against its net deferred tax assets as of September 30, 2016. At June 30, 2016, the Company has available net operating loss carry forwards for federal income tax reporting purposes of approximately $288.7 million and for state income tax reporting purposes of approximately $108.5 million, which expire at various dates between fiscal 2017 and 2036. Pursuant to Section 382 of the Internal Revenue Code of 1986, as amended, the annual utilization of a company’s net operating loss and research credit carry forwards may be limited if the Company experiences a change in ownership as defined in Section 382 of the Internal Revenue Code. The Company’s net operating loss carry forwards available to offset future federal taxable income arising before such ownership changes may be limited. Similarly, the Company may be restricted in using its research credit carry forwards arising before such ownership changes to offset future federal income tax expense. The Company’s U.S. operations reported a net loss for the three-month periods ended September 30, 2016 and 2015, resulting in a tax benefit that was fully offset by a valuation allowance. Income taxes were provided for profitable foreign jurisdictions during the first three months of fiscal 2016 at the estimated annual tax rate. The foreign jurisdictions during the first three months of fiscal 2017 reported a net loss, resulting in a tax benefit that was fully offset by a valuation allowance. The Company has no liability for uncertain tax positions as of September 30, 2016. Net Loss Per Share Allocable to Common Stockholders Net loss per basic and diluted common share allocable to common stockholders is based on the net loss for the relevant period, divided by the weighted-average number of common shares outstanding during the period. For purposes of the diluted net loss per common share calculations, the exercise or conversion of all potential common shares is not included because their effect would have been anti-dilutive, due to the net loss recorded for the three-month periods ended September 30, 2016 and 2015. The common stock equivalents excluded from the diluted per share calculation are 26,762,930 and 27,839,015 shares at September 30, 2016 and 2015, respectively. Net Comprehensive Loss Net comprehensive loss consists of net loss, unrealized loss on available for sale securities and foreign exchange translation adjustments and is presented in the condensed consolidated statements of comprehensive loss. Recently Issued Accounting Pronouncements In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows: Clarification of Certain Cash Receipts and Cash Payments”, which eliminates the diversity in practice related to the classification of certain cash receipts and payments in the statement of cash flows, by adding or clarifying guidance on eight specific cash flow issues. ASU 2016-15 is effective for annual and interim reporting periods beginning after December 15, 2017 and early adoption is permitted. ASU 2016-15 provides for retrospective application for all periods presented. The Company is assessing ASU 2016-15’s impact and will adopt it when effective. In March 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting” which simplified several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Public companies will be required to adopt this standard in annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted in any interim or annual period provided that the entire standard is adopted. The Company does not expect ASU 2016-09 to have a material impact on the consolidated financial statement presentation. In February 2016, the FASB issued ASU 2016-02, “ Leases ”. This standard requires a lessee to record on the balance sheet the assets and liabilities for the rights and obligations created by lease terms of more than 12 months. The amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, and early application is permitted. The Company is assessing ASU 2016-02’s impact and will adopt it when effective. In August 2014, the FASB issued ASU 2014-15, “ Presentation of Financial Statements – Going Concern: Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern ”. This guidance clarifies that an entity’s management should evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. The amendments in this update are effective for annual reporting periods ending after December 15, 2016, and annual and interim periods thereafter, and early application is permitted. The Company is assessing ASU 2014-15’s impact and will adopt it when effective. On May 28, 2014, the FASB issued ASU 2014-09, “ Revenue from Contracts with Customers, ” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In August 2015, with the issuance of ASU 2015-14, the FASB amended the effective date of this ASU to fiscal years beginning after December 15, 2017, and early adoption is permitted only for fiscal years beginning after December 15, 2016. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is assessing ASU 2014-09’s impact and will adopt it when effective.

Convertible Senior Notes [Abstract]
Convertible Senior Notes	4. In February 2015, the Company issued $100.0 million of Convertible Senior Notes (net proceeds of approximately $96.3 million after deducting the initial purchasers’ fees and offering expenses) in a private offering exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”), in reliance upon Rule 144A under the Securities Act. The Convertible Senior Notes will mature on February 15, 2020, unless earlier purchased or converted. The debt issuance costs of approximately $3.7 million, primarily consisting of underwriting, legal and other professional fees, are amortized over the term of the Convertible Senior Notes. The Convertible Senior Notes are senior unsecured obligations of the Company. Interest at 4.75% is payable semiannually on February 15 and August 15 of each year. The effective interest rate on the Convertible Senior Note was 5.48% for the period from the date of issuance through September 30, 2016. The Convertible Senior Notes are convertible at the option of holders into approximately 19.6 million shares of Immunomedics common stock at any time prior to the close of business on the day immediately preceding the maturity date. The conversion rate will initially be 195.8336 shares of common stock per $1,000 principal amount of Convertible Senior Notes (equivalent to an initial conversion price of approximately $5.11 per share of Immunomedics common stock). If the Company undergoes a fundamental change (as defined in the indenture governing the Convertible Senior Notes), holders may require Immunomedics to purchase for cash all or part of the Convertible Senior Notes at a purchase price equal to 100% of the principal amount of the Convertible Senior Notes to be purchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change purchase date, subject to certain exceptions. In addition, if certain make-whole fundamental changes (as defined in the indenture governing the Convertible Senior Notes) occur, Immunomedics will, in certain circumstances, increase the conversion rate for any Convertible Note converted in connection with such make-whole fundamental change. The indenture does not limit the amount of debt which may be issued by the Company under the indenture or otherwise, does not contain any financial covenants or restrict the Company from paying dividends, selling or disposing of assets, or issuing or repurchasing its other securities, provided that such event is not deemed to be a fundamental change (as defined in the indenture governing the Convertible Senior Notes). The indenture contains customary terms and covenants and events of default. If an event of default with respect to the Convertible Senior Notes occurs, holders may, upon satisfaction of certain conditions, accelerate the principal amount of the Convertible Senior Notes plus premium, if any, and accrued and unpaid interest, if any. In addition, the principal amount of the Convertible Senior Notes plus premium, if any, and accrued and unpaid interest, if any, will automatically become due and payable in the case of certain types of bankruptcy or insolvency events of default involving the Company. Total interest expense for the Convertible Senior Notes for both three-month periods ended September 30, 2016 and 2015 was $1.4 million. Included in interest expense is the amortization of debt issuance costs of $0.2 million for both three-month periods ended September 30, 2016 and 2015.

Estimated Fair Value of Financial Instruments [Abstract]
Estimated Fair Value of Financial Instruments	5. The Company’s financial instruments consist of cash and cash equivalents, marketable securities, accounts receivable, accounts payable and accrued expenses, and Convertible Senior Notes. The carrying amount of accounts receivable, accounts payable and accrued expenses are generally considered to be representative of their respective fair values because of the short-term nature of those instruments as of September 30, 2016 and June 30, 2016. The Company has categorized its other financial instruments, based on the priority of the inputs to the valuation technique, into a three-level fair value hierarchy as set forth below. If the inputs used to measure the financial instruments fall within different levels of the hierarchy, the categorization is based on the lowest level input that is significant to the fair value measurement of the instrument. Financial instruments recorded on the condensed consolidated balance sheets as of September 30, 2016 and June 30, 2016 are categorized based on the inputs to the valuation techniques as follows (in thousands): · Level 1 – Financial instruments whose values are based on unadjusted quoted prices for identical assets or liabilities in an active market which the company has the ability to access at the measurement date (examples include active exchange-traded equity securities and most U.S. Government and agency securities). · Level 2 – Financial instruments whose value are based on quoted market prices in markets where trading occurs infrequently or whose values are based on quoted prices of instruments with similar attributes in active markets. · Level 3 – Financial instruments whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. These inputs reflect management’s own assumptions about the assumptions a market participant would use in pricing the asset.

Stock Incentive Plan [Abstract]
Stock Incentive Plan	7. The Company has a stock incentive plan, the Immunomedics, Inc. 2014 Long-Term Incentive Plan (the “Plan”), that includes a discretionary grant program, a stock issuance program and an automatic grant program. The plan was established to promote the interests of the Company, by providing eligible persons with the opportunity to acquire a proprietary interest in the Company as an incentive to remain with the organization and to align the employee’s interest with our stockholders. Under the Plan option awards are generally granted with an exercise price equal to the closing price of the Company’s common stock on the date of grant. Those option awards generally vest based on four years of continuous service and have seven year contractual terms. Option awards that are granted to non-employee Board members under the annual option grant program are granted with an exercise price equal to the closing price of the Company’s common stock on the date of grant, are vested immediately and have seven year contractual terms. At September 30, 2016, there were 15,723,248 shares of common stock reserved for possible future issuance under the Plan, both currently outstanding (6,179,570 shares) and those available to be issued for future grants (9,543,678 shares). The weighted average fair value at the date of grant for options granted during the three-month periods ended September 30, 2016 and 2015 were $1.75 and $0.87 per share, respectively. The Company uses historical data to estimate employee forfeitures for employees, executive officers and outside directors. The expected term of options granted represents the period of time that options granted are expected to be outstanding and the expected stock price volatility is based on the Company’s daily stock trading history. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Information concerning options for the three-month period ended September 30, 2016 is summarized as follows: Weighted Weighted Average Average Remaining Aggregate Exercise Contractual Intrinsic Shares Price Life Value (in 000’s) Outstanding, July 1, 2016 $ Granted $ Exercised $ Cancelled or forfeited $ Outstanding, September 30, 2016 $ 3.93 $ Exercisable, September 30, 2016 $ 3.12 $ A summary of the Company’s non-vested restricted and performance stock units at September 30, 2016, and changes during the three-month period ended September 30, 2016 are presented below: Weighted-Average per Share of Outstanding Non-Vested Market Value on Restricted and Performance Stock Units Number of Awards Grant Date Non-vested at July 1, 2016 $ Restricted Units Granted (a) $ Vested/Exercised $ Non-vested at September 30, 2016 $ (a) For the three-month period ended September 30, 2016, 106,061 restricted stock units were awarded to the Company’s President and Chief Executive Officer.

All or a portion of the Performance Units vest based upon the level of achievement of the milestones set forth in each agreement, which is expected to be achieved within five years of the grant date. The Performance Units that vest based upon attainment of the performance milestone will be exercisable based on a percentage basis on the attainment of anniversary dates. During the three-month period ended September 30, 2016, the Company awarded 9,746 of these restricted stock units to the executive officers as a result of achieving certain continued service requirements.

Collaboration Agreement [Abstract]
Collaboration Agreement	10. The Bayer Group (formerly Algeta ASA) In fiscal 2013 the Company entered into a collaboration agreement, referred to herein as the Collaboration Agreement, with Algeta ASA (subsequently acquired by The Bayer Group “Bayer”), for the development of epratuzumab to be conjugated with Algeta’s proprietary thorium-227 alpha-pharmaceutical payload. Under the terms of the Collaboration Agreement, the Company manufactured and supplied clinical-grade epratuzumab to Bayer, which has rights to evaluate the potential of a Targeted Thorium Conjugate (TTC), linking thorium-227 to epratuzumab, for the treatment of patients with cancer. Bayer has the right to terminate the Collaboration Agreement with three months prior written notice, subject to certain provisions. Bayer will fund all non-clinical and clinical development costs up to the end of Phase 1 clinical testing. Upon successful completion of Phase 1 testing, the parties shall negotiate terms for a license agreement at Bayer’s request. The Company and Bayer have agreed to certain parameters in the Collaboration Agreement. Under the terms of the Collaboration Agreement, as amended, Immunomedics received an upfront cash payment and other payments aggregating $6.0 million, which have been recognized in prior periods upon the Company fulfilling its obligations under the Collaboration Agreement. For the year ended June 30, 2015, the Company recognized $1.0 million in license and other revenue for the completion of the clinical development milestone as described in the Collaboration Agreement, which required the shipment of sufficient quantities of clinical grade material to Bayer to complete their Phase 1 clinical trial. In addition, in January 2016 and 2015, the Company recorded revenue of $0.3 million representing an anniversary payment under the agreement. The contract provides for the Company to receive one more similar payment of $0.3 million, representing “anniversary payment” over the 2017 fiscal year.

Commitments and Contingencies [Abstract]
Commitments and Contingencies	11. Employment Contracts Effective July 1, 2015, the Company entered into the Amended and Restated Employment Agreement with Dr. Goldenberg pertaining to Dr. Goldenberg’s service to the Company as the Company’s Chairman of the Board, Chief Scientific Officer and Chief Patent Officer. The Amended and Restated Goldenberg Agreement will continue, unless earlier terminated by the parties, until July 1, 2020. Dr. Goldenberg’s current annual base salary under the Amended and Restated Goldenberg Agreement is $0.6 million, which shall be reviewed annually for appropriate increases by the Board or the Compensation Committee. Dr. Goldenberg is also eligible to participate in the Company’s incentive compensation plan in place for its senior level executives. Dr. Goldenberg’s annual bonus target is 50% of his base salary, subject to achievement of performance goals established by the Compensation Committee, with a potential payout from 0 to 150% of the target amount. For the 2016 fiscal year, the strategic goal to out-license sacituzumab govitecan was not met. Taking into account the importance to the Company of out-licensing sacituzumab govitecan, the Compensation Committee determined that although certain individual performance goals were met, the Company’s overall strategic plan had not been accomplished and, therefore, that any cash incentive payment that Dr. Goldenberg was eligible for, based on his performance during 2016, would not be granted. Dr. Goldenberg will also be eligible to receive equity compensation awards under the Plan, or any such successor equity compensation plan as may be in place from time to time, at the discretion of the Compensation Committee. In lieu of any annual performance equity or equity-based grants throughout the term of the Amended and Restated Goldenberg Agreement, Dr. Goldenberg received a grant of 1,500,000 Restricted Stock Units (as such term is defined in the Plan), which shall vest, if at all, after the three 3 year period commencing on the grant date of July 14, 2015, provided the applicable milestones based on achievement of certain market conditions (stock prices) are met and conditioned upon Dr. Goldenberg's continued employment through the vesting period, subject to the terms and conditions of the Restricted Stock Units Notice and the Restricted Stock Units Agreement and such other terms and conditions as set forth in the grant agreement. Dr. Goldenberg is also eligible to receive certain additional incentive compensation during the agreement term. For any fiscal year in which the Company records an annual net loss, Dr. Goldenberg shall receive a sum equal to 0.75% of the consideration the Company receives from any licensing agreement, sale of intellectual property or similar transaction with any third party, with certain exceptions as defined in the Goldenberg Agreement. For any fiscal year in which the Company records net income, Dr. Goldenberg shall receive a sum equal to 1.50% of the Company’s Annual Net Revenue as defined in the Goldenberg Agreement for each such fiscal year, and thereafter throughout the non-competition period, as described in the Agreement. Dr. Goldenberg is also eligible to receive royalty payments on royalties received by the Company. For each fiscal year the Company shall pay Dr. Goldenberg a sum equal to a percentage of the annual royalties the Company receives on each of the products for which Dr. Goldenberg is an Inventor, and all products using, related to or derived from products for which Dr. Goldenberg is an Inventor. The percentage of royalties that the Company will pay to Dr. Goldenberg on each patented product will be determined based on the percentage of royalties that the Company must pay to external third parties. Dr. Goldenberg is also eligible to receive minimum payments of $150 thousand during each of the fiscal years, payable in equal quarterly payments, as an advance against the amounts due as additional incentive compensation, royalty payments and dispositions of undeveloped assets. In the event the Company completes a disposition of the Company’s undeveloped assets for which Dr. Goldenberg was an Inventor, the Company will pay Dr. Goldenberg a sum equal to at least twenty percent or more of the consideration the Company receives from each disposition. The Company’s obligation to compensate Dr. Goldenberg upon dispositions of undeveloped assets applies to all dispositions completed within the contract term or within three years thereafter. For the 2016, 2015 and 2014 fiscal years, Dr. Goldenberg received the minimum payment under the employment agreement. Dr. Goldenberg also is compensated by IBC Pharmaceuticals as discussed in greater detail below. Cynthia L. Sullivan Effective July 1, 2014, the Company entered into the Fifth Amended and Restated Employment Agreement with Cynthia L. Sullivan pertaining to Ms. Sullivan’s service to the Company as the Company’s President and Chief Executive Officer (the “Amended Sullivan Agreement”), which terminates on June 30, 2017. Ms. Sullivan’s current annual base salary under the Amended Sullivan Agreement is $0.7 million, which is reviewed annually for appropriate increases by the Board or the Compensation Committee. Ms. Sullivan’s annual bonus target is 50% of her base salary, subject to achievement of performance goals, with a potential payout from 0% to 150% of the target amount. For the 2016 fiscal year, the strategic goal to out-license sacituzumab govitecan was not met. Taking into account the importance to the Company of out-licensing sacituzumab govitecan, the Compensation Committee determined that although certain individual performance goals were met, the Company’s overall strategic plan had not been accomplished and, that any cash incentive payment that Ms. Sullivan was eligible for, based on her performance during 2016, would not be granted. Ms. Sullivan is also eligible to receive equity compensation awards under the Plan, or any such successor equity compensation plan as may be in place from time to time. Legal Matters The following is a summary of legal matters that are outstanding: Patent litigation: Immunomedics filed a first amended complaint on October 22, 2015 and a second amended complaint on January 14, 2016 in the United States District Court for the District of New Jersey, against Roger Williams Medical Center (“RWMC”), Richard P. Junghans, M.D., Ph.D. and Steven C. Katz, M.D. The second amended complaint alleges that RWMC and Dr. Junghans breached a Material Transfer Agreement (“MTA”) through which it provided to them a monoclonal antibody known as MN-14 and related materials. Defendants are alleged to have breached the MTA and to have been negligent by, among other things, using the materials beyond the agreed-upon Research Project, sharing confidential information, failing to provide Immunomedics with a right of first refusal, failing to notify Immunomedics of intended publications prior to publishing, and refusing to return the materials upon request. Immunomedics also asserts defendants: claims of conversion, tortious interference, unjust enrichment, and infringement of three patents owned by Immunomedics. On January 28, 2016, defendants filed an Answer to the Second Amended Complaint. Immunomedics and defendants are currently engaged in fact discovery and the exchange of patent disclosures. Shareholder complaints: Class Action Shareholder Federal Securities Cases. Two purported class action cases have been filed in the United States District Court for the District of New Jersey; namely, Fergus v. Immunomedics, Inc., et al., No. 2:16-cv-03335, filed June 9, 2016; and Becker v. Immunomedics, Inc., et al., No. 2:16-cv-03374, filed June 10, 2016. These cases arise from the same alleged facts and circumstances, and seek class certification on behalf of purchasers of our common stock between April 20, 2016 and June 2, 2016 (with respect to the Fergus matter) and between April 20, 2016 and June 3, 2016 (with respect to the Becker matter). These cases concern the Company's statements in press releases, investor conference calls, and SEC filings beginning in April 2016 that the Company would present updated information regarding its IMMU-132 breast cancer drug at the 2016 American Society of Clinical Oncology ("ASCO") conference in Chicago, Illinois. The complaints allege that these statements were false and misleading in light of June 2, 2016 reports that ASCO had cancelled the presentation because it contained previously reported information. The complaints further allege that these statements resulted in artificially inflated prices for our common stock, and that the Company and certain of its officers are thus liable under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934. As of the date hereof, service of the initiating papers in these actions has not been made on the Company. Other matters: Immunomedics is also a party to various claims and litigation arising in the normal course of business, which includes some or all of certain of its patents. While it is not possible to determine the outcome of these matters, the Company believes that the resolution of all such matters will not have a material adverse effect on its consolidated financial position or liquidity, but could possibly be material to its consolidated results of operations in any one accounting period.

Summary of Significant Accounting Policies [Abstract]
Principles of Consolidation and Presentation	Principles of Consolidation and Presentation The condensed consolidated financial statements include the accounts of Immunomedics and its subsidiaries. Noncontrolling interests in consolidated subsidiaries in the condensed consolidated balance sheets represent minority stockholders’ proportionate share of the deficit in such subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Financial Instruments	Financial Instruments The carrying amounts of cash and cash equivalents, other current assets and current liabilities approximate fair value due to the short-term maturity of these instruments. The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents.
Marketable Securities	Marketable Securities Marketable securities, all of which are available-for-sale, consists of corporate debt securities, U.S. bonds, U.S. sponsored agencies and municipal bonds. Corporate debt securities include Eurodollar issues of U.S. corporations, and U.S. dollar denominated issues of foreign corporations. Marketable securities are carried at fair value, with unrealized gains and losses, net of related income taxes, reported as accumulated other comprehensive loss, except for losses from impairments which are determined to be other-than-temporary. Realized gains and losses, and declines in value judged to be other-than-temporary on available-for-sale securities are included in the determination of net loss and are included in interest and other income (net), at which time the average cost basis of these securities are adjusted to fair value. Fair values are based on quoted market prices at the reporting date. Interest and dividends on available-for-sale securities are included in interest and other income (net).
Inventory	Inventory Inventory, which consists of raw materials, work-in-process and the finished product of LeukoScan ® , is stated at the lower of cost (which approximates first-in, first-out) or market, and includes materials, labor and manufacturing overhead.
Revenue Recognition	Revenue Recognition The Company has accounted for revenue arrangements that include multiple deliverables as a separate unit of accounting if both of the following criteria are met: a) the delivered item has value to the customer on a standalone basis, and b) if the right of return exists, delivery of the undelivered items is considered probable and substantially in the control of the vendor. If these criteria are not met, the revenue elements must be considered a single unit of accounting for purposes of revenue recognition. The Company allocates revenue consideration, excluding contingent consideration, based on the relative selling prices of the separate units of accounting contained within an arrangement containing multiple deliverables. Relative selling prices are determined using vendor specific objective evidence, if it exists; otherwise third-party evidence or the Company’s best estimate of selling price is used for each deliverable. Payments received under contracts to fund certain research activities are recognized as revenue in the period in which the research activities are performed. Payments received in advance that are related to future performance are deferred and recognized as revenue when the research projects are performed. Upfront nonrefundable fees associated with license and development agreements where the Company has continuing involvement in the agreement are recorded as deferred revenue and recognized over the estimated service period. The Company estimates the period of continuing involvement based on the best evidential matter available at each reporting period. If the estimated service period is subsequently modified, the period over which the upfront fee is recognized is modified accordingly on a prospective basis. In order to determine the revenue recognition for contingent milestones, the Company evaluates the contingent milestones using the criteria as provided by the Financial Accounting Standards Boards (“FASB”) guidance on the milestone method of revenue recognition, as explained in ASU 2010-17, “ Milestone Method of Revenue Recognition,” at the inception of a collaboration agreement. The criteria requires that (i) the Company determines if the milestone is commensurate with either its performance to achieve the milestone or the enhancement of value resulting from the Company’s activities to achieve the milestone, (ii) the milestone be related to past performance, and (iii) the milestone be reasonable relative to all deliverable and payment terms of the collaboration arrangement. If these criteria are met then the contingent milestones can be considered as substantive milestones and will be recognized as revenue in the period that the milestone is achieved. Royalties are recognized as earned in accordance with the terms of various research and collaboration agreements. Revenue from the sale of diagnostic products is recorded when there is persuasive evidence that an arrangement exists, delivery has occurred, the price is fixed and determinable or collectability is reasonably assured. Allowances, if any, are established for uncollectible amounts, estimated product returns and discounts. Since allowances are recorded based on management’s estimates, actual amounts may be different in the future.
Research and Development Costs	Research and Development Costs Research and development costs are expensed as incurred. Costs incurred for clinical trials for patients and investigators are expensed as services are performed in accordance with the agreements in place with the institutions.
Reimbursement of Research & Development Costs	Reimbursement of Research & Development Costs Research and development costs that are reimbursable under collaboration agreements are included as a reduction of research and development expenses. The Company records these reimbursements as a reduction of research and development expenses as the Company’s partner in the collaboration agreement has the financial risks and responsibility for conducting these research and development activities.
Stock-Based Compensation	Stock-Based Compensation The Company utilizes stock-based compensation in the form of stock options, stock appreciation rights, stock awards, stock unit awards, performance shares, cash-based performance units and other stock-based awards, each of which may be granted separately or in tandem with other awards. The grant-date fair value of stock awards is based upon the underlying price of the stock on the date of grant. The grant-date fair value of stock option awards must be determined using an option pricing model. Option pricing models require the use of estimates and assumptions as to (a) the expected term of the option, (b) the expected volatility of the price of the underlying stock and (c) the risk-free interest rate for the expected term of the option. The Company uses the Black-Scholes-Merton option pricing formula for determining the grant-date fair value of such awards. The expected term of the option is based upon the contractual term and expected employee exercise and expected post-vesting employment termination behavior. The expected volatility of the price of the underlying stock is based upon the historical volatility of the Company’s stock computed over a period of time equal to the expected term of the option. The risk free interest rate is based upon the implied yields currently available from the U.S. Treasury yield curve in effect at the time of the grant. Pre-vesting forfeiture rates are estimated based upon past voluntary termination behavior and past option forfeitures. The following table sets forth the weighted-average assumptions used to calculate the fair value of options granted for the three-month periods ended September 30, 2016 and 2015: Three Months Ended September 30, 2016 2015 Expected dividend yield 0% 0% Expected option term (years) 5.05 5.03 Expected stock price volatility 62% 56% Risk-free interest rate 1.16% - 1.21% 1.51% - 1.61% The Company uses historical data to estimate forfeitures. The expected term of options granted represents the period of time that options granted are expected to be outstanding. Expected stock price volatility was calculated based on the Company’s daily stock trading history. The risk-free rate for periods within the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Changes in any of these assumptions could impact, potentially materially, the amount of expense recorded in future periods related to stock-based awards.
Income Taxes	Income Taxes The Company uses the asset and liability method to account for income taxes, including the recognition of deferred tax assets and deferred tax liabilities for the anticipated future tax consequences attributable to differences between financial statement amounts and their respective tax bases. The Company reviews its deferred tax assets for recovery. A valuation allowance is established when the Company believes that it is more likely than not that its deferred tax assets will not be realized. Changes in valuation allowances from period to period are included in the Company’s tax provision in the period of change. The Company has recorded a full valuation allowance against its net deferred tax assets as of September 30, 2016. At June 30, 2016, the Company has available net operating loss carry forwards for federal income tax reporting purposes of approximately $288.7 million and for state income tax reporting purposes of approximately $108.5 million, which expire at various dates between fiscal 2017 and 2036. Pursuant to Section 382 of the Internal Revenue Code of 1986, as amended, the annual utilization of a company’s net operating loss and research credit carry forwards may be limited if the Company experiences a change in ownership as defined in Section 382 of the Internal Revenue Code. The Company’s net operating loss carry forwards available to offset future federal taxable income arising before such ownership changes may be limited. Similarly, the Company may be restricted in using its research credit carry forwards arising before such ownership changes to offset future federal income tax expense. The Company’s U.S. operations reported a net loss for the three-month periods ended September 30, 2016 and 2015, resulting in a tax benefit that was fully offset by a valuation allowance. Income taxes were provided for profitable foreign jurisdictions during the first three months of fiscal 2016 at the estimated annual tax rate. The foreign jurisdictions during the first three months of fiscal 2017 reported a net loss, resulting in a tax benefit that was fully offset by a valuation allowance. The Company has no liability for uncertain tax positions as of September 30, 2016.
Net Loss Per Share Allocable to Common Stockholders	Net Loss Per Share Allocable to Common Stockholders Net loss per basic and diluted common share allocable to common stockholders is based on the net loss for the relevant period, divided by the weighted-average number of common shares outstanding during the period. For purposes of the diluted net loss per common share calculations, the exercise or conversion of all potential common shares is not included because their effect would have been anti-dilutive, due to the net loss recorded for the three-month periods ended September 30, 2016 and 2015. The common stock equivalents excluded from the diluted per share calculation are 26,762,930 and 27,839,015 shares at September 30, 2016 and 2015, respectively.
Net Comprehensive Loss	Net Comprehensive Loss Net comprehensive loss consists of net loss, unrealized loss on available for sale securities and foreign exchange translation adjustments and is presented in the condensed consolidated statements of comprehensive loss.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows: Clarification of Certain Cash Receipts and Cash Payments”, which eliminates the diversity in practice related to the classification of certain cash receipts and payments in the statement of cash flows, by adding or clarifying guidance on eight specific cash flow issues. ASU 2016-15 is effective for annual and interim reporting periods beginning after December 15, 2017 and early adoption is permitted. ASU 2016-15 provides for retrospective application for all periods presented. The Company is assessing ASU 2016-15’s impact and will adopt it when effective. In March 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting” which simplified several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Public companies will be required to adopt this standard in annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted in any interim or annual period provided that the entire standard is adopted. The Company does not expect ASU 2016-09 to have a material impact on the consolidated financial statement presentation. In February 2016, the FASB issued ASU 2016-02, “ Leases ”. This standard requires a lessee to record on the balance sheet the assets and liabilities for the rights and obligations created by lease terms of more than 12 months. The amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, and early application is permitted. The Company is assessing ASU 2016-02’s impact and will adopt it when effective. In August 2014, the FASB issued ASU 2014-15, “ Presentation of Financial Statements – Going Concern: Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern ”. This guidance clarifies that an entity’s management should evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. The amendments in this update are effective for annual reporting periods ending after December 15, 2016, and annual and interim periods thereafter, and early application is permitted. The Company is assessing ASU 2014-15’s impact and will adopt it when effective. On May 28, 2014, the FASB issued ASU 2014-09, “ Revenue from Contracts with Customers, ” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In August 2015, with the issuance of ASU 2015-14, the FASB amended the effective date of this ASU to fiscal years beginning after December 15, 2017, and early adoption is permitted only for fiscal years beginning after December 15, 2016. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is assessing ASU 2014-09’s impact and will adopt it when effective.
