Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Note 1. Organization, Use of Estimates and Basis of Presentation
	Champions Oncology, Inc. (the “Company”), is engaged in the development and sale of advanced technology solutions and products to personalize the development and use of oncology drugs. The Company’s TumorGraft Technology Platform is a novel approach to personalizing cancer care based upon the implantation of human tumors in immune-deficient mice. The Company uses this technology, in conjunction with related services, to offer solutions for two consumer groups: Personalized Oncology Solutions (“POS”) and Translational Oncology Solutions (“TOS”). POS assists physicians in developing personalized treatment options for their cancer patients through tumor specific data obtained from drug panels and related personalized oncology services. The Company’s TOS business offers a technology platform to pharmaceutical and biotechnology companies using proprietary TumorGraft studies, which the Company believes may be predictive of how drugs may perform in clinical settings.
	The Company has three operating subsidiaries: Champions Oncology (Israel), Limited, Champions Biotechnology U.K., Limited and Champions Oncology Singapore, PTE LTD. For the three and nine months ended January 31, 2015 and 2014, there were no material revenues earned by these subsidiaries.
	The Company’s foreign subsidiaries functional currency is the U.S. dollar. Transaction gains and losses are recognized in earnings. The Company is subject to foreign exchange rate fluctuations in connection with the Company’s international operations.
	These unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission or the SEC. All significant intercompany transactions and accounts have been eliminated. All figures are presented in thousands of U.S. dollars, except share data, or except where expressly stated otherwise. Certain information related to the Company’s organization, significant accounting policies and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States or GAAP has been condensed or omitted. The accounting policies followed in the preparation of these unaudited condensed consolidated financial statements are consistent with those followed in the Company’s annual consolidated financial statements for the year ended April 30, 2014, as filed on Form 10-K. In the opinion of management, these unaudited condensed consolidated financial statements contain all material adjustments necessary to fairly state our financial position, results of operations and cash flows for the periods presented and the presentations and disclosures herein are adequate when read in conjunction with the Company’s Annual Report on Form 10-K for the year ended April 30, 2014.
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
	Reclassification
	Certain prior year amounts have been reclassified to conform to the current year presentation.
	Earnings Per Share
	Basic net loss per share is computed by dividing the net loss for the period by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by dividing the net loss for the period by the weighted-average number of shares of common stock plus dilutive potential common stock considered outstanding during the period. Such dilutive shares consist of incremental shares that would be issued upon exercise of the Company’s derivative warrants.

	Total common stock equivalents		27,116,675			25,910,622
	Liquidity
	Our liquidity needs have typically arisen from the funding of our research and development programs and the launch of new products, working capital requirements, and other strategic initiatives. In the past, we have met these cash requirements through our sales of products and services, cash and cash equivalents, working capital management, and proceeds from certain private placements of our securities. As of January 31, 2015, we had negative working capital of $4.7 million and cash and cash equivalents on hand of $0.2 million.
	On March 11, 2015, (the Company entered into a 2015 Securities Purchase Agreement (the "2015 Securities Purchase Agreement") with related party and non-related party investors for the sale to the investors of units, each unit consisting of one share of the Company's Common Stock, par value $0.001 per share (the "Common Stock") and a warrant to buy 0.55 shares of Common Stock at $0.48 per share (the "Warrants"), at a purchase price of $0.40 per unit, for an aggregate of $14,000,000. See Note 10 for more detail.
	As of March 17, 2015, Management believes that the Company has sufficient cash on hand to continue as a going concern for at least the next 12 months.
	Provision for Income Taxes
	Deferred income taxes have been provided to show the effect of temporary differences between the recognition of expenses for financial and income tax reporting purposes and between the tax basis of assets and liabilities, and their reported amounts in the consolidated financial statements. As of January 31, 2015 and 2014, the Company provided a valuation allowance for all net deferred tax assets, as it is not more likely than not that the assets will not be recovered based on an insufficient history of earnings.
	The income tax provision for the nine months ended January 31, 2015 was $27 as compared to $13 for the corresponding period in the previous year, and primarily consists of income tax obligations payable to the foreign jurisdictions.
	There were no uncertain tax position identified by the Company.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	Note 2. Recently Issued Accounting Pronouncements
	In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers”, which will replace most existing revenue recognition guidance in U.S. Generally Accepted Accounting Principles and is intended to improve and converge with international standards the financial reporting requirements for revenue from contracts with customers. The core principle of ASU 2014-09 is that an entity should recognize revenue for the transfer of goods or services equal to the amount that it expects to be entitled to receive for those goods or services. ASU 2014-09 also requires additional disclosures about the nature, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. ASU 2014-09 allows for both retrospective and prospective methods of adoption and is effective for periods beginning after December 15, 2016. The Company is currently evaluating the impact that the adoption of ASU 2014-09 will have on our financial statements.
	In June 2014, FASB has issued Accounting Standards Update (“ASU”) No. 2014-12, “Compensation – Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period”. This ASU requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. This update further clarifies that compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered.. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Earlier adoption is permitted. The adoption of this standard is not expected to have a material impact on the Company’s condensed consolidated balance sheets and results of operations.
	In August 2014, FASB issued Accounting Standards Update (“ASU”) 2014-15, “Presentation of Financial Statements — Going Concern: Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern”. This ASU requires management to evaluate, in connection with preparing financial statements for each annual and interim reporting period, whether there are conditions or events, considered in the aggregate, that raise substantial doubt about an entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the date that the financial statements are available to be issued when applicable) and provide related disclosures. ASU 2014-15 is effective for the annual period ending after December 15, 2016, and for annual and interim periods thereafter. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2014-15 on its financial statements.

	The Company has in place a 2010 Equity Incentive Plan and a 2008 Equity Incentive Plan. In general, these plans provide for stock-based compensation in the form of (i) Non-statutory Stock Options; (ii) Restricted Stock Awards; and (iii) Stock Appreciation Rights to the Company’s employees, directors and non-employees. The plans also provide for limits on the aggregate number of shares that may be granted, the term of grants and the strike price of option awards.
	Stock-based compensation in the amount of $657 and $941 was recognized for the three months ended January 31, 2015 and 2014, respectively and $2,284 and $1,968 for the nine months ended January 31, 2015 and 2014, respectively.  As of January 31, 2015, $158 of stock compensation is included within accrued liabilities line item on the balance sheet.

	Included in the beginning balances outstanding in the table above are 3,000,000 options granted to the Company’s Chief Executive Officer and President which vest based on service criteria and 3,000,000 options granted to the Company’s Chief Executive Officer and President which vest based on performance criteria.  The service-based conditions of these options provide for vesting to occur monthly over a period of three years.  Since the straight-line method is not available for performance or market-based share-based payments, the 3,000,000 performance-based options will be expensed on an accelerated basis once the Company determines it is probable that the performance-based conditions will be met.
	Stock Purchase Warrants
	As of January 31, 2015 and April 30, 2014, the Company had warrants outstanding for the purchase of 3,276,667 shares of its common stock, all of which were exercisable. Of these warrants, 1,266,667 were issued in connection with the April 2011 Private Placement and 1,860,000 were issued in connection with the January 2013 Private Placement and are accounted for as liabilities. The remaining 150,000 warrants, with an exercise price of $1.00, were accounted for as equity instruments and expired on July 31, 2014. Activity related to these warrants, which expire at various dates through April 2016, is summarized as follows (dollars in thousands):
							Weighted
				Weighted			Average
		Number		Average			Remaining		Aggregate
		of		Exercise			Contractual		Intrinsic
		Shares		Price			Life (Years)		Value
	Outstanding, May 1, 2014	3,276,667		$	0.61		2.9		$	984
	Granted	-			-		-			-
	Exercised	-			-		-			-
	Expired	-150,000			-		-			-
	Outstanding, January 31, 2015	3,126,667		$	0.6		2.3		$	-
	The warrants issued in connection with both the April 2011 Private Placement and January 2013 Private Placement contain certain exercise price reset provisions. Under these provisions, the exercise price of the warrants may be adjusted downward should the Company have future sales of its Common Stock for no consideration or for a consideration per share less than the Per Share Price (as such term is defined in the April 2011 Private Placement and January 2013 Private Placement). These exercise price reset provisions resulted in a downward adjustment to the exercise price of the warrants issued in the April 2011 Private Placement from $0.90 to $0.50.
	The Company has accounted for the warrants issued in connection with the April 2011 Private Placement and January 2013 Private Placement as a liability based on the exercise price reset provisions described above. This liability, which is recorded at fair value on the accompanying consolidated balance sheets, totaled $0.8 million at the time of the close of the January 2013 Private Placement Agreement. As of January 31, 2015 and April 30, 2014, the fair value of these warrants was $0.6 million and $2.01 million, respectively. The change in fair value of these warrants has been, and will be, recognized as other income (expense) on the Company’s consolidated statements of operations. The fair value of these warrants was calculated by the Monte Carlo simulation valuation method. Assumptions used to calculate the fair value of these warrants were as follows:
		January 31,		April 30,
		2015		2014
	Expected term in years	1.2 - 3.0		1.9 - 3.7
	Risk-free interest rates	0.6% - 1.05%		0.4% - 1.17%
	Volatility	73% - 100%		95% - 113%
	Dividend yield	0%		0%
	The Company estimated the volatility based upon the applicable look-back periods or historical volatility observed for the Company. For the Risk-free rate the Company used the yield on a T-bill with maturity closest to the expected time to the warrant expiration.
	In addition to the assumptions above, the Company also takes into consideration whether or not the Company would participate in another round of financing and if that financing is registered or not and what that stock price would be for the financing at that time.
	The Company will continue to adjust the warrant liability for changes in fair value until the earlier of the exercise of the warrants, at which time the liability will be reclassified to stockholders' equity, or expiration of the warrants.
	The Company has granted demand registration rights in connection with the investment in common shares and the common shares underlying the warrants for both the April 2011 Private Placement and January 2013 Private Placement. These rights include the requirement of the Company to file certain registration statements within a specified time period and to have these registration statements declared effective within a specified time period. If the Company is not able to comply with these registration requirements, the Company will be required to pay cash penalties equal to 1.0% of the aggregate Purchase Price paid by the investors for each 30-day period in which a Registration Default, as defined in the Securities Purchase Agreement, exists. These penalties are subject to a 10% limit of the aggregate Purchase Price paid by the investors. The Company may become subject to these penalty provisions if it fails to have a registration statement for the common shares declared effective, or to maintain the effectiveness of such registration statement. The total amount of potential penalties under this registration payment arrangement ranges from $50 to $130 for each 30-day period in which a registration default exists; however, as of January 31, 2015 and April 30, 2014, and through the date of this filing, the Company does not believe these penalties to be probable and accordingly, has not established an accrual for such registration payment arrangements.

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	Note 8. Fair Value
	The carrying value of cash and cash equivalents, accounts receivable, prepaid expenses, deposits and other receivables, accounts payable, and accrued liabilities approximate their fair value based on the liquidity or the short-term maturities of these instruments. The fair value hierarchy promulgated by GAAP consists of three levels:
		·	Level one — Quoted market prices in active markets for identical assets or liabilities;
		·	Level two — Inputs other than level one inputs that are either directly or indirectly observable; and
		·	Level three — Unobservable inputs developed using estimates and assumptions, which are developed by the reporting entity and reflect those assumptions that a market participant would use.
	Determining which category an asset or liability falls within the hierarchy requires significant judgment. The Company evaluates its hierarchy disclosures each quarter. The Company has one liability measured at fair value on a recurring basis, which are warrants that were issued in connection with private placements of the Company’s securities that are discussed more fully in Note 4. As of January 31, 2015 and April 30, 2014, these warrants had an estimated fair value of $0.6 million and $2.01 million, respectively, which was calculated by the Monte Carlo simulation valuation method using level three inputs. The Company has no assets that are measured at fair value on a recurring basis and there were no assets or liabilities measured at fair value on a non-recurring basis during the nine months ended January 31, 2015 and 2014.
	The following table presents information about our warrants liability, which was our only financial instrument measured at fair value on a recurring basis using significant unobservable inputs (Level 3) as of January 31, 2015 and April 30, 2014 (in thousands):

	On February 28, 2015, the Company entered into amendments to the convertible promissory notes issued on December 1, 2014. The amendments extended the maturity dates of the convertible promissory notes to April 1, 2015 (see Note 5).
	On March 11, 2015, the Company entered into a 2015 Securities Purchase Agreement (the "2015 Securities Purchase Agreement") with Battery Ventures IX, L.P. and Battery Investment Partners IX, LLC (collectively, "Battery"), New Enterprise Associates 14, Limited Partnership ("NEA"), Joel Ackerman, Chief Executive Officer and a director of the Company ("Ackerman"), Dr. Ronnie Morris, President and a director of the Company ("Morris"), Daniel Mendelson, a director of the Company ("Mendelson") and certain other investors (collectively with Battery, NEA, Ackerman, Morris and Mendelson, the "Investors"), for the sale to the Investors of units, each unit consisting of one share of the Company's Common Stock, par value $0.001 per share (the "Common Stock") and a warrant to buy 0.55 shares of Common Stock at $0.48 per share (the "Warrants"), at a purchase price of $0.40 per unit, for an aggregate of $14,000,000. The Warrants expire five years after the closing date. Ackerman and Morris converted convertible promissory notes dated December 1, 2014 in the principal amounts of $1 million each, plus accrued interest, into the units at a 5% discount, pursuant to the terms of the convertible promissory notes.
	The Investors have the right to require the Company to repurchase the purchased shares (the "Put Option") for cash for $0.40 per share upon a change of control or sale or exclusive license of substantially all of the Company's assets only if approved by the Company's board of directors. The Put Option will terminate upon the achievement of certain financial and other milestones.
	The Investors have certain participation rights with respect to future financings of the Company. The Company covenanted to register the resale of the shares of Common Stock to be issued to the Investors and the shares of Common Stock issuable upon exercise of the Warrants pursuant to a 2015 Amended and Restated Registration Rights Agreement, to pay certain liquidated damages if the Company fails to file such registration statement by a certain deadline, and to have it declared effective by a certain deadline or keep it effective for a certain period of time.
	The issuance of the shares of Common Stock resulted in the Company issuing an additional  1,865,853 shares of Common Stock to investors who purchased shares of Common Stock pursuant to a Securities Purchase Agreement dated as of March 24, 2011 (the "2011 Securities Purchase Agreement") due to contractual antidilution provisions in that 2011 Securities Purchase Agreement. The Company also amended and restated the 2011 Securities Purchase Agreement to eliminate these antidilution provisions going forward, and conform aspects of the put option in that 2011 Securities Purchase Agreement to terms of the Put Option in the 2015 Securities Purchase Agreement. The Company also issued an additional 1,583,335 warrants to its investors under the 2011 Warrants Agreements under the Securities Purchase Agreement and had its investors agree on certain amendments of the warrants to eliminate the antidilution rights for future transactions, by extending the term of the warrants  by one year, and revising the exercise price to $0.40.
	The Company and its investors have  amended and restated its Securities Purchase Agreement dated January 28, 2013 (the "2013 Securities Purchase Agreement") to conform aspects of the put option in that 2013 Securities Purchase Agreement to the Put Option in the 2015 Securities Purchase Agreement. The Company issued an additional 1,209,001 warrants to investors under the 2013 Warrant Agreements under the Securities Purchase Agreement and had its investors agree on certain amendments of these warrants issued in connection with the 2013 Securities Purchase Agreement to eliminate the antidilution rights for future transactions, by extending the term of the warrant  by one year, revising the exercise price to $0.40.
