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. or the Company, is engaged in the development 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 customer groups:
| · | Our Personalized Oncology Solutions, or POS, business, which provides services to physicians and patients looking for information to help guide the development of personalized treatment plans.
| · | Our Translational Oncology Solutions, or TOS, business, which provides services to pharmaceutical and biotechnology companies seeking personalized approaches to drug development that will lower costs and increase the speed of developing new drugs, as well as increase the adoption of existing drugs.
The Company has three operating subsidiaries: Champions Oncology (Israel), Limited, Champions Biotechnology U.K., Limited and Champions Oncology Singapore, PTE LTD. To date, there have been no material revenues earned by these subsidiaries. The financial statements of the Company’s foreign subsidiaries, all of which have a functional currency other than the U.S. dollar, have been translated into the U.S. dollar for the Company’s consolidated financial statements for each period being presented. Translation gains and losses are recognized as a component of accumulated other comprehensive loss in the accompanying consolidated balance sheets. Transaction gains and losses are recognized in earnings in other (expense) income. 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, 2013, 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, 2013. 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. Basic loss per share is calculated by dividing loss available to common shareholders by the weighted average number of common shares (including redeemable common stock) outstanding for the year. Diluted loss per share is calculated based on the weighted average number of common shares (including redeemable common stock) outstanding for the year, plus the dilutive effect of common stock purchase warrants, stock options and restricted stock units using the treasury stock method. Contingently issuable shares are included in the calculation of basic earnings per share when all contingencies surrounding the issuance of the shares are met and the shares are issued or issuable. Contingently issuable shares are included in the calculation of dilutive earnings per share as of the beginning of the reporting period if, at the end of the reporting period, all contingencies surrounding the issuance of the shares are satisfied or would be satisfied if the end of the reporting period were the end of the contingency period. Due to the net losses for the three and six months ended October 31, 2013 and 2012, basic and diluted loss per share were the same, as the effect of potentially dilutive securities would have been anti-dilutive. The following table reflects the total potential share-based instruments outstanding at October 31, 2013 and 2012 that could have an effect on the future computation of dilution per common share:
|  | October 31, |
|  | 2013 |  | 2012 |
Stock options |  | 15,473,955 |  | 14,643,955 |
Warrants |  | 3,276,667 |  | 1,416,667 |
Total common stock equivalents |  | 18,750,622 |  | 16,060,622 |
