Basis Of Presentation	'
	1. Basis of Presentation
	The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The consolidated financial statements include the accounts of Aratana Therapeutics, Inc. (the “Company” or “Aratana”) and its wholly owned subsidiaries. The Company has one operating segment. All intercompany balances and transactions have been eliminated in consolidation. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements of the Company for the year ended December 31, 2013 and the notes thereto in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 26, 2014. In the opinion of management, all adjustments, consisting of a normal and recurring nature, considered necessary for a fair presentation, have been included.
	The Company expects that its cash, cash equivalents, and short-term investments, which include the net proceeds received in its public offering of common stock that closed on September 22, 2014, and existing Credit Facility (Note 11) will fund operations through December 31, 2016.

Summary Of Significant Accounting Policies [Abstract]	'
Summary Of Significant Accounting Policies	'
	2. Summary of Significant Accounting Policies
	Use of Estimates
	The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. Actual results could differ from those estimates.
	Cash and Cash Equivalents
	In 2013, the Company held no overnight reverse repurchase agreements. Beginning in 2014, the Company accounts for its overnight reverse repurchase agreements as cash equivalents.
	Revenue Recognition
	During 2013, the Company’s principal revenue streams were product sales and licensing revenue. Beginning in 2014, as a result of the Okapi Sciences, NV (“Okapi Sciences”) acquisition (Note 4), the Company generates revenue from research and development services. Revenues from the performance of research and development services are recorded as Licensing and collaboration revenue in the consolidated statements of operations and are recognized on a proportional basis as costs are incurred.
	Accounting for Stock Based Compensation
	In 2013, the Company used expected volatility based on the historical volatility of publicly-traded peer companies. Beginning in the first quarter of 2014, expected volatility is based on historical volatility of the Company’s stock as adequate historical data regarding the volatility of the Company’s common stock price became available.
	Reverse Repurchase Agreements
	In 2013, the Company held no reverse repurchase agreements. Beginning in 2014, the Company accounts for its reverse repurchase agreements with maturities greater than overnight as short-term investments and classifies them as available-for-sale.
	Derivative Financial Instruments
	In 2013, the Company held no derivative financial instruments. Beginning in 2014, the Company accounts for its derivative instruments as either assets or liabilities and carries them at fair value. The Company’s sole derivative (Note 6) has not been designated as a hedging instrument and is adjusted to fair value through current income.
	Foreign Currency
	During 2013, the Company had limited foreign currency exposure. With the acquisition of Okapi Sciences (Note 4) in 2014, the Company is exposed to effects of foreign currency from translation. Transactions in foreign currencies are translated into the relevant functional currency at the rate of exchange at the date of the transaction. Transaction gains and losses are recognized in arriving at loss from operations. The results of operations for subsidiaries, whose functional currency is not the U.S. Dollar, are translated into the U.S. Dollar at the average rates of exchange during the period, with the subsidiaries’ balance sheets translated at the rates accumulated at the balance sheet date. The cumulative effect of exchange rate movements is included in a separate component of other comprehensive income (loss) in the consolidated balance sheet. Gains and losses arising from intercompany foreign currency transactions are included in loss from operations unless the gains and losses arise from permanent differences in intercompany accounts. Gains and losses from permanent differences in intercompany accounts are included in a separate component of other comprehensive income (loss).
	Comprehensive Loss
	For the year ended December 31, 2013, there was no difference between net loss and comprehensive loss. During the first nine months of 2014, there were differences between net loss and comprehensive loss. The Company includes foreign currency translation adjustments related to the translation of foreign subsidiaries’ balance sheets, permanent differences in intercompany accounts and unrealized holding gains and losses on available-for-sale securities in comprehensive loss.
	Goodwill
	The Company completed its annual goodwill impairment testing during the third quarter of 2014.  The Company elected to bypass the qualitative assessment. The Company determined as of the testing date that it still consisted of one operating segment which is comprised of one reporting unit. In performing step one of the assessment,  the Company determined that its fair value, determined to be its market capitalization, was greater than its carrying value, determined to be stockholder’s equity. Based on this result, step two of the assessment was not required to be performed, and the Company determined there was no impairment of goodwill as of the testing date.
	New Accounting Pronouncements
	Revenue from Contracts with Customers
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued guidance on recognizing revenue in contracts with customers. The guidance affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards (e.g., insurance contracts or lease contracts). This guidance will supersede the revenue recognition requirements in topic, Revenue Recognition, and most industry-specific guidance. This guidance also supersedes some cost guidance included in subtopic, Revenue Recognition – Construction-Type and Production-Type Contracts. In addition, the existing requirements for the recognition of a gain or loss on the transfer of nonfinancial assets that are not in a contract with a customer (e.g., assets within the scope of topic, Property, Plant, and Equipment, and tangible assets within the scope of topic, Intangibles – Goodwill and Other) are amended to be consistent with the guidance on recognition and measurement (including the constraint on revenue) in this guidance.
	The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.
	These changes become effective for the Company on January 1, 2017 and early adoption is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is currently assessing the impact, if any, this new guidance will have on the Company’s financial condition, results of operations or cash flows.
	Development Stage Entities — Elimination of Certain Financial Reporting Requirements, Including an Amendment to Variable Interest Entities Guidance, Consolidations
	In June 2014, the FASB issued guidance that removes all incremental reporting requirements from GAAP for development stage entities, including the removal of the topic development stage entities. These changes eliminate the requirement to report inception-to-date information in the statements of income, cash flows, and shareholder equity. These changes become effective for the Company on January 1, 2015 and early adoption is permitted. The Company opted to adopt this guidance as of June 30, 2014. The adoption of this guidance resulted in decreased financial statement disclosures, but did not impact the Company’s financial condition, results of operations or cash flows.
	Disclosure of Uncertainties about an Entities Ability to Continue as a Going Concern
	In August 2014, the FASB issued guidance which requires management to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide disclosure in the footnotes under certain circumstances. This guidance is effective for fiscal years ending after December 15, 2016 with early adoption permitted. The Company does not expect that this guidance will have a material impact on its consolidated financial statements.

		-1		Contingent consideration consists of a current portion of $2,572 and long-term portion of $1,543 on the consolidated balance sheet.
	Certain estimates and judgments are required to develop the fair value amounts shown above. The fair value amounts shown above are not necessarily indicative of the amounts that the Company would realize upon disposition, nor do they indicate the Company’s intent or ability to dispose of the financial instrument.
	The following methods and assumptions were used to estimate the fair value of each material class of financial instrument:
		·		Cash equivalents – the fair value of the cash equivalents has been determined to be amortized cost.
		·		Reverse repurchase agreements – the fair value of the reverse repurchase agreements has been determined to be amortized cost.
		·		Marketable securities (long-term) – the fair value of marketable securities has been based on quoted prices in active markets or exchanges for identical assets.
		·		Marketable securities (short-term) – the fair value of marketable securities has been estimated based on quoted prices in active markets prices for identical assets or for similar assets in markets that are not active
		·		Derivative financial instruments – the fair value of the derivative instruments has been estimated using a modified Black-Scholes model. Inputs into the Black-Scholes model include interest rates, stock volatilities and dividends data.
		·		Contingent consideration – the fair value of the contingent consideration payable has been estimated using the income approach using a probability weighted discounted cash flow method. Inputs into the discounted cash flow method include the probability of and period in which the relevant milestone event is expected to be achieved and the discount rate to be applied in calculating the present values of the relevant milestones.
	Transfers Between Levels of the Fair Value Hierarchy
	Transfers between levels of the fair value hierarchy are reported at the beginning of the reporting period in which they occur. During the three and nine months ended September 30, 2014, transfer of investments between Level 1 and Level 2 were $1,029. In the third quarter of 2014, the Company re-classified its investment in Advaxis (Note 13) to a Level 1 investment from Level 2, because the Company is no longer precluded from selling shares due to restrictions imposed by Rule 144 of the Securities Act of 1933. Previously, the Company calculated a lack of marketability discount on the fair value of the Advaxis common stock because of trading restrictions on the shares. The Company considered the inputs used to calculate the lack of marketability discount Level 2 inputs and, as a result, the Company classified this investment as Level 2. The Company determined the lack of marketability discount by using a Black-Scholes model to value a hypothetical put option to approximate the cost of hedging the stock until the restriction ended.
	During the year ended December 31, 2013, there were no transfers between levels of the fair value hierarchy.
	Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis Using Significant Unobservable Inputs (Level 3)
	The change in the fair value of the Company’s contingent consideration payable, which is measured at fair value on a recurring basis using significant unobservable inputs (Level 3), is as follows:
	Contingent consideration
			2014
	As of January 1		$	4,115
	Initial recognition of contingent consideration payable			15,166
	Settlement of contingent consideration payable			-15,235
	Expense recognized in the consolidated statement of operations (within general and administrative) due to change in fair value			123
	As of the end of the period		$	4,169
	Quantitative Information about Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis Using Significant Unobservable Inputs (Level 3)
	Quantitative information about the Company’s recurring Level 3 fair value measurements is included below:
	Financial liabilities:
			FAIR VALUE AT MEASUREMENT DATE
					Valuation		Significant			(Weighted
	At September 30, 2014		Fair value		technique		unobservable inputs		Range	Average)
	Contingent consideration		$	4,169	Income approach (probability weighted discounted cash flow)		Probability of milestones being achieved		47.50% to 95.00%	-75.55%
							Assumed market participant discount rate		5.50%
							Periods in which milestones are expected to be achieved		2014 to 2015
	Contingent consideration payable represents the future amount the Company may be required to pay in conjunction with the Vet Therapeutics, Inc. (“Vet Therapeutics”) acquisition in October 2013. The amount of contingent consideration which may ultimately be payable by the Company in relation to the Vet Therapeutics acquisition is dependent upon the achievement of specified future milestones, such as certain regulatory and manufacturing milestones for AT-004. The Company assesses the probability, and estimated timing, of these milestones being achieved and re-measures the related amounts of contingent consideration at each balance sheet date.
	The fair value of the Company’s contingent consideration payable could significantly increase or decrease due to changes in certain assumptions which underpin the fair value measurements. Each set of assumptions and milestones are specific to the contingent consideration payable. The assumptions include, among other things, the probability and expected timing of certain milestones being achieved. The Company regularly reviews these assumptions, and makes adjustments to the fair value measurements as required by facts and circumstances.
	Financial Assets and Liabilities that are not Measured at Fair Value on a Recurring Basis
	The carrying amounts and estimated fair value as at September 30, 2014 and December 31, 2013 of the Company’s financial assets and liabilities which are not measured at fair value on a recurring basis are as follows:
		30-Sep-14
		Carrying Amount		Fair Value
Financial liabilities:
Loan payable (Level 2)		$	14,957	$	16,358
		31-Dec-13
		Carrying Amount		Fair Value
Financial liabilities:

Certain estimates and judgments were required to develop the fair value amounts. The fair value amount shown above is not necessarily indicative of the amounts that the Company would realize upon disposition, nor do they indicate the Company’s intent or ability to dispose of the financial instrument.

	Acquisition of Okapi Sciences
	On January 6, 2014, the Company acquired Okapi Sciences, a Leuven, Belgium based company with a proprietary antiviral platform and three clinical/development stage product candidates. This acquisition further expanded the existing Company pipeline. The aggregate purchase price was approximately $44,439, which consisted of $14,139 in cash, a promissory note in the principal amount of $15,134 with a maturity date of December 31, 2014, and a contingent consideration of up to $16,308 with an acquisition fair value of $15,166. The promissory note bore interest at a rate of 7% per annum, payable quarterly in arrears, and was subject to mandatory prepayment in the event of a specified equity financing by the Company. On February 4, 2014, the promissory note and accrued interest was paid in cash in the amount of $15,158. On March 17, 2014, the contingent consideration was settled in cash in the amount of $15,235.
	Included in the Company’s consolidated statements of operations for the three and nine months ended September 30, 2014 is revenue totaling approximately $0 and $452, respectively, related to Okapi Sciences.
	The acquisition-date fair value of the consideration transferred to the sellers of Okapi Sciences, less cash acquired, was $43,376, which consisted of the following:
	Cash consideration	$	14,139
	Fair value of promissory note		15,134
	Fair value of contingent consideration		15,166
	Fair value of total consideration		44,439
	Less cash acquired		-1,063
	Total consideration transferred, net of cash acquired	$	43,376
	Fair Value of Contingent Consideration: The Company agreed to pay up to $16,308 on or prior to April 7, 2014, subject to mandatory prepayment in cash in the event of a specified future equity financing, provided that if not paid in cash by April 7, 2014, payment was to be made in the form of shares of the Company’s common stock based on the average closing price of the Company’s common stock during the 10-trading day period ending April 4, 2014, subject to a maximum of 1,060,740 shares and a minimum of 707,160 shares. This contingent consideration was recorded as a liability and measured at fair value using a probability-weighted model utilizing significant observable and unobservable inputs, including the volatility in the market price of the Company’s common stock, the expected probability of settling the contingent consideration in either cash or shares and an estimated discount rate commensurate with the risks of these outcomes. The analysis resulted in an estimated fair value of contingent consideration of $15,166. The contingent consideration was settled March 17, 2014 for $15,235 and the difference between the initial fair value amount and settlement amount was $69 which is reflected as a charge to general and administrative expenses in the consolidated statement of operations.
	The acquisition of Okapi Sciences was accounted for as a business combination under the acquisition method of accounting. Accordingly, the assets acquired and liabilities assumed were recorded at fair value with the remaining purchase price recorded as goodwill. The assets acquired and the liabilities assumed from Okapi Sciences have been recorded at their fair values at the date of acquisition, being January 6, 2014. The Company’s consolidated financial statements and results of operations include the results of Okapi Sciences from January 6, 2014.
	In the nine months ended September 30, 2014 the Company incurred expenses totaling $161 relating to the Okapi Sciences acquisition, which were recorded within General and administrative expenses in the Company’s consolidated statement of operations.
	The Company has preliminarily valued the acquired assets and assumed liabilities based on their estimated fair values. These estimates are subject to change as additional information becomes available, including finalization of certain tax matters and finalization of the working capital adjustment. The preliminary fair values included in the consolidated balance sheet as of September 30, 2014 are based on the best estimates of management. The completion of the valuation may result in adjustments to the carrying value of Okapi Sciences’ assets and liabilities, revision of useful lives of intangibles assets, the determination of any residual amount that will be allocated to goodwill and the related tax effects. The related amortization of acquired assets is also subject to revision based on the final valuation. Any adjustments to the preliminary fair values will be made as soon as practicable but no later than one year from the January 6, 2014 acquisition date.
	The Company’s allocation of the purchase price to the assets acquired and liabilities assumed was as follows:
	Cash	$	1,063
	Accounts receivable		149
	Other receivables		60
	Prepaid expenses and other current assets		82
	Property and equipment		217
	Other long-term assets		18
	Identifiable intangible assets		29,400
	Accounts payable and accrued expenses		-586
	Deferred revenue		-83
	Deferred tax liabilities, net		-3,588
	Long-term debt		-4
	Total identifiable net assets		26,728
	Goodwill		17,711
	Total net assets acquired		44,439
	Less:
	Promissory note		15,134
	Contingent consideration		15,166
	Cash paid	$	14,139
	The following are the intangible assets acquired by drug program and their estimated useful lives as of the date of the acquisition:
		FAIR VALUE		USEFUL LIFE
	AT-006	$	3,400	13 years
	AT-007		13,500	15 years
	AT-008		5,300	13 years
	AT-011		7,200	14 years
	Total intangible assets subject to amortization	$	29,400
	The identifiable intangible assets recognized by the Company as a result of the Okapi Sciences acquisition relate to Okapi Sciences technology, and consist primarily of its intellectual property related to Okapi Sciences AT-006, AT-007, AT-008 and AT-011 programs, and the estimated net present value of future cash flows from commercial agreements related to the AT-006 program.
	All Okapi Sciences programs, which were considered in-process research and development (“IPR&D”) at the acquisition date, were valued using a multi-period excess earnings method, a form of the income approach, which incorporates the estimated future cash flows to be generated from this technology. Excess earnings are the earnings remaining after deducting the market rates of return on the estimated values of contributory assets, including debt-free net working capital, tangible, and intangible assets. The excess earnings are thereby calculated for each year of a multi-year projection period and discounted to present value. Accordingly, the primary components of this method consist of the determination of excess earnings and an appropriate rate of return.
	The Company will not amortize the assets related to the Okapi Sciences programs until commercialization has been achieved.
	The preliminary valuation analysis conducted by the Company determined that the aggregate fair value of identifiable assets acquired less the aggregate fair value of identifiable liabilities assumed by the Company is less than the purchase price. As the purchase price exceeds the fair value of assets and liabilities acquired or assumed, goodwill will be recognized. Goodwill is calculated as the difference between the Okapi Sciences acquisition date fair value of the consideration transferred and the fair values of the assets acquired and liabilities assumed. The goodwill is not expected to be deductible for income tax purposes. Goodwill is recorded as an indefinite-lived asset and is not amortized but tested for impairment on an annual basis or when indications of impairment exist.
	The difference between the total consideration and the fair value of the net assets acquired of $17,711 was recorded as Goodwill in the consolidated balance sheet. This goodwill represents the excess of the purchase price over the fair value of the tangible and identifiable intangible assets acquired and liabilities assumed, principally representing the tax attributes of the acquisition and certain operational and strategic synergies such as advancement toward becoming a commercial company and acquiring a proprietary antiviral platform.
	Pro Forma Financial Information
	The following pro forma financial information summarizes the combined results of operations for the Company as though the acquisition of Okapi Sciences occurred on January 1, 2013. The unaudited pro forma financial information is as follows:
		THREE MONTHS ENDED		NINE MONTHS ENDED

	Net loss per share attributable to common stockholders—basic and diluted	$	-0.24	$	-1.89
	The pro forma financial information for all periods presented has been calculated after adjusting the results of the Company and Okapi Sciences to reflect the business combination accounting effects resulting from these acquisitions including the amortization expenses from acquired intangible assets, the depreciation expenses from acquired tangible assets, the stock-based compensation expense for unvested stock options and restricted stock units assumed and the related tax effects as though the acquisition occurred as of January 1, 2013. The pro forma financial information is for informational purposes only and is not indicative of the results of operations that would have been achieved if the acquisition had taken place at the beginning of the Company’s 2013 fiscal year.

	At September 30, 2014, unrealized losses in the amount of $171 were recorded as a component of other comprehensive loss. As of September 30, 2014, no gross unrealized losses related to individual securities had been in a continuous loss position for 12 months or longer.
	As of September 30, 2014, the Company considers the declines in market value of its marketable securities investment portfolio to be temporary in nature and does not consider any of its investments other-than-temporarily impaired. Fair values were determined for each individual security in the investment portfolio. When evaluating an investment for other-than-temporary impairment, the Company reviews factors such as the length of time and extent to which fair value has been below its cost basis, the financial condition of the issuer and any changes thereto, and the Company’s intent to sell, or whether it is more likely than not it will be required to sell the investment before recovery of the investment’s cost basis. During the three months and nine months ended September 30, 2014, the Company did not recognize any impairment charges.
	Reverse Repurchase Agreements
	The Company, as part of its cash management strategy, may invest excess cash in reverse repurchase agreements. All reverse repurchase agreements are tri-party and have maturities of 90 days or less at time of investment. The underlying collateral is U.S. government securities including U.S. treasuries, agency debt and agency mortgage securities. The underlying collateral posted by each counterparty is required to cover 102% of the principal amount and accrued interest after the application of a discount to fair value. The Company classifies overnight reverse repurchase agreements and term reverse repurchase agreements as cash equivalents and short-term investments, respectively on the consolidated balance sheet.

In January 2014, the Company completed its acquisition of Okapi Sciences. The fair value of consideration exceeded the fair value of assets and liabilities acquired which resulted in goodwill of $17,711.
	Goodwill is recorded as an indefinite-lived asset and is not amortized for financial reporting purposes but is tested for impairment on an annual basis or when indications of impairment exist. No goodwill impairment losses have been recognized. Goodwill is not expected to be deductible for income tax purposes. The Company performs its annual impairment test of the carrying value of the Company’s goodwill during the third quarter of each year.

Debt	'
	11. Debt
	Converted Loans
	On March 4, 2013, the Company entered into a credit facility (the “Credit Facility”) with Square 1 Bank (“Square 1”) as lender. The Credit Facility provided for an initial term loan of $5,000 in principal (the “Initial Term Loan”) and additional term loans not to exceed $5,000 in principal, with total borrowings not to exceed $10,000.  On October 11, 2013, the Company and Vet Therapeutics entered into an amendment of the Credit Facility (the “Credit Facility Amendment”), which, among other things, increased the amount that remained available for the Company to draw by an additional $5,000, to a total of $10,000 (the “Additional Term Loan”). Simultaneously with the closing of the Credit Facility Amendment on October 11, 2013, the Company borrowed the total $10,000 available, and upon consummation of the merger with Vet Therapeutics, Vet Therapeutics became a co-borrower under the Credit Facility.
	On June 13, 2014, the Company and Vet Therapeutics entered into an additional amendment of the Credit Facility (the “Second Credit Facility Amendment”), which, among other things, converted $15,000 in outstanding term loans under the Credit Facility into non-revolving loans (the “Converted Loans”) and modified certain terms and conditions of the loans, including fixing the interest rate at a fixed annual rate of 5.50%. The Company is obligated to make interest-only payments on any loans funded under the Credit Facility until June 13, 2016, on which date such non-revolving term loans will be due. If the Company and Vet Therapeutics remain in compliance with the terms of the Credit Facility through June 13, 2016 and Square 1, the Company and Vet Therapeutics mutually agree to new financial covenants, the Company and Vet Therapeutics shall have the option (subject to Square 1’s agreement to such new financial covenants) to amortize the principal amount of the loans under the Credit Facility starting on June 13, 2016. If the Company and Vet Therapeutics elect to amortize the principal amount of the loans under the Credit Facility on June 13, 2016 (subject to Square 1’s agreement to new financial covenants), the principal amount of the loans shall be payable in 24 equal monthly installments of principal, plus all accrued but unpaid interest, beginning on the date that is one month immediately following June 13, 2016.
	Simultaneously with the closing of the Second Credit Facility Amendment on June 13, 2014, the Company entered into a pledge and security agreement with Square 1, pursuant to which the Company pledged 65% of the issued and outstanding shares of Wildcat Acquisition BVBA, a private limited liability company formed in Belgium and a wholly owned subsidiary of the Company, to Square 1 as collateral under the Credit Facility.
	On the issuance date of March 4, 2013, the Initial Term Loan was recorded in the consolidated balance sheet, net of discount of $73, related to fees assessed by the lender at the time of borrowing. The additional $11 of fees assessed by Square 1 in connection with the Second Credit Facility Agreement were capitalized and will be recognized over the term of the loan as the amendment was determined to be a debt modification. The carrying value of this debt is being accreted to the principal amount of the debt by charges to interest expense using the effective-interest method over the two-year term of the term to the maturity date of June 13, 2016. At September 30, 2014, the debt discount balance totaled $43. Accretion amounts recognized as interest expense for the three months and nine months ended September 30, 2014 were $6 and $21, respectively.
	Estimated future principal payments under the Credit Facility, as amended are as follows:
	YEARS ENDING DECEMBER 31,

	2015		—
	2016		15,000
	2017		—

	Total	$	15,000
	During the three months and nine months ended September 30, 2014, the Company recognized $222 and $654 of interest expense related to the Credit Facility, respectively.
	Promissory Note
	In connection with the acquisition of Vet Therapeutics, the Company executed a promissory note in the principal amount of $3,000 with a maturity date of December 31, 2014. The promissory note bore interest at a rate of 7% per annum, payable quarterly in arrears, and was subject to prepayment in the event of specified future equity financings by the Company. On February 4, 2014, the promissory note and accrued interest of $20 was paid by the Company.

	During the three and nine months ended September 30, 2014, the Company recognized $0 and $452, respectively, of research and development services revenue related to the NAH AT-006 Agreement. As of September 30, 2014, the Company had not accrued or received any milestone or royalty payments since execution of the NAH AT-006 Agreement.
	Advaxis Inc. (“Advaxis”)
	On March 19, 2014, the Company entered into an Exclusive License Agreement with Advaxis (the “Advaxis Agreement”) that granted the Company global rights for development and commercialization of licensed animal health products for Advaxis’ ADXS-cHER2 for the treatment of osteosarcoma in dogs (“AT-014”) and three additional cancer immunotherapy products for the treatment of three other types of cancer. Under the terms of the Advaxis Agreement, the Company paid $2,500 in exchange for the license, 306,122 shares of common stock, and a warrant to purchase 153,061 shares of common stock. The consideration was allocated to the common stock and warrant based on their fair values on the date of issuance of $1,200 and $643, respectively. The remaining consideration of $657 was allocated to the licensed technology. On the date of acquisition, the licensed technology had not reached technological feasibility in animal health indications and had no alternative future use in the field of animal health. Accordingly, in-process research and development of $657 was expensed upon acquisition. The Company will be required to pay Advaxis milestone payments of up to an additional $6,000 in clinical and regulatory milestones for each of the four products, assuming approvals in both cats and dogs, in both the United States and the European Union. In addition, the Company agreed to pay up to $28,500 in commercial milestones, as well as tiered royalties ranging from mid-single digit to 10% on the Company’s product sales, if any.

	Under the terms of the subscription agreement, the Company acquired 306,122 shares of common stock and a warrant to purchase another 153,061 shares of common stock for $1,843. The warrant is exercisable through March 19, 2024, at an exercise price of $4.90 per share of common stock and is to be settled through physical share issuance or net share settlement where the total number of issued shares is based on the amount the market price of common stock exceeds the exercise price of $4.90 on date of exercise. Neither the common stock nor warrant have registration rights. The Company allocated the consideration of $1,843 to Advaxis common stock ($1,200) and the Advaxis warrant ($643) based on their respective fair values and recorded the purchase in marketable securities and other long-term assets, respectively. See Note 3 for subsequent fair value matters related to the Advaxis common stock and warrant.
	Vet-Stem, Inc. (“Vet-Stem”)
	On June 12, 2014, the Company entered into an Exclusive License Agreement with Vet-Stem (the “Vet-Stem Agreement”) that granted the Company the exclusive United States rights for commercialization and development of Vet-Stem’s allogeneic stem cells being developed for the treatment of pain and inflammation of canine osteoarthritis (“AT-016”). Vet-Stem is responsible for the development and obtaining regulatory approval of AT-016 and the Company is responsible for the commercialization. Under the terms of the Vet-Stem Agreement, the Company paid an initial license fee of $500. On the date of acquisition, the licensed technology had not reached technological feasibility in animal health indications and had no alternative future use in the field of animal health. Accordingly, in-process research and development of $500 was expensed upon acquisition. The Company will be required to pay Vet-Stem milestone payments of up to $4,500 upon Vet-Stem’s achievement of certain development and regulatory milestones, as well as tiered royalties on the Company’s product sales, if any. The Company could be required to pay to Vet-Stem up to $3,600 in reimbursement for development expenses, unless additional monies are approved by the joint steering committee.
	The Company expects Vet-Stem to achieve multiple development and regulatory milestones related to the Vet-Stem Agreement within the next twelve months.
	Atopix Therapeutics Ltd.
	On October 10, 2014, the Company entered into an Exclusive License Agreement with Atopix (the “Atopix Agreement”) that granted the Company the exclusive global rights for development and commercialization of licensed animal health products for Atopix’s CRTH2 antagonist for the treatment of atopic dermatitis (“AT-018”). Under the terms of the Atopix Agreement, the Company paid an initial license fee of $1,000. On the date of acquisition, the licensed technology had not reached technological feasibility in animal health indications and had no alternative future use in the field of animal health. Accordingly, in-process research and development of $1,000 will be expensed upon acquisition in the fourth quarter of 2014. The Company will be required to pay Atopix milestone payments of up to an additional $4,500 in clinical and regulatory milestones, assuming approvals in both cats and dogs, in both the United States and the European Union, as well as tiered royalties in the mid-single digits on the Company’s product sales, if any.
	The Company does not expect to achieve additional milestones related to the Atopix Agreement within the next twelve months.
	RaQualia Pharma Inc. (“RaQualia”)
	In October 2014, the Company received notice that Active Pharmaceutical Ingredient (“API”) delivered to RaQualia was accepted. Per the terms of the AT-001 RaQualia API Development Agreement, the Company was entitled to an $800 payment for the successful development and delivery of the API to RaQualia.

	In February 2013, the board of directors of the Company approved an amendment of the Company’s Certificate of Incorporation and increased the number of authorized shares of common stock to 25,041,667. On July 2, 2013, the Company increased the number of authorized shares of its common stock from 25,041,667 to 100,000,000, par value $0.001 per share.
	Treasury Stock
	As part of the Company’s stock plans, the Company offers employees the opportunity to make required tax payments with cash or through a net share settlement. For employees choosing net share settlement, the Company makes required tax payments on behalf of employees as their stock awards vest and then withholds a number of vested shares having a value on the date of vesting equal to the tax obligation. The shares withheld are recorded as treasury shares. During the three and nine months ended September 30, 2014, the Company repurchased 576 and 5,449 shares, respectively, in settlement of employees’ tax obligations for a total of $7 and $95, respectively or an  average of $12.31 and $17.44 per share, respectively. The Company accounts for treasury stock using the cost method.
	On April 15, 2014, the Company purchased 71,918 shares from a former stockholder of a subsidiary of the Company in a non-recurring private transaction for $986 or $13.71 per share.
	Reverse Stock Split
	On May 22, 2013, the Company effected a 1-for-1.662 reverse stock split of its issued and outstanding shares of common stock. No fractional shares were issued in connection with the reverse stock split. Accordingly, all share and per share amounts for all periods presented in these consolidated financial statements and notes thereto have been adjusted retroactively, where applicable, to reflect the reverse stock split.
	Stock-Based Awards
	The Company issued common stock pursuant to the 2010 Equity Incentive Plan during the year ended December 31, 2013, and both 2010 Equity Incentive Plan and 2013 Incentive Award Plan for the nine months ended September 30, 2014, and year ended December 31, 2013 (Note 15).

	On May 7, 2014 the Company amended its corporate office lease in Kansas City, Kansas with MPM Heartland House, LLC, a company in which the current Chief Executive Officer and President of the Company, also a director of the Company, is the principal owner. The amendment was made effective May 1, 2014. Under the terms of the amendment, the Company expanded leased office space, shared access areas and parking spaces for a total rent of $115 per year. All other lease terms remain unaltered. The Company believes the terms of the lease agreement, as amended, are no less favorable than those that the Company could have obtained from an unaffiliated third party.

Summary of Significant Accounting Policies (Policy)	9 Months Ended
	Sep. 30, 2014
Summary Of Significant Accounting Policies [Abstract]	'
Use Of Estimates	'
	Use of Estimates
	The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. Actual results could differ from those estimates.
Cash And Cash Equivalents	'
	Cash and Cash Equivalents
	In 2013, the Company held no overnight reverse repurchase agreements. Beginning in 2014, the Company accounts for its overnight reverse repurchase agreements as cash equivalents.
Revenue Recognition	'
	Revenue Recognition
	During 2013, the Company’s principal revenue streams were product sales and licensing revenue. Beginning in 2014, as a result of the Okapi Sciences, NV (“Okapi Sciences”) acquisition (Note 4), the Company generates revenue from research and development services. Revenues from the performance of research and development services are recorded as Licensing and collaboration revenue in the consolidated statements of operations and are recognized on a proportional basis as costs are incurred.
Accounting For Stock Based Compensation	'
	Accounting for Stock Based Compensation
	In 2013, the Company used expected volatility based on the historical volatility of publicly-traded peer companies. Beginning in the first quarter of 2014, expected volatility is based on historical volatility of the Company’s stock as adequate historical data regarding the volatility of the Company’s common stock price became available.
Reverse Repurchase Agreements	'
	Reverse Repurchase Agreements
	In 2013, the Company held no reverse repurchase agreements. Beginning in 2014, the Company accounts for its reverse repurchase agreements with maturities greater than overnight as short-term investments and classifies them as available-for-sale.
Derivative Financial Instruments	'
	Derivative Financial Instruments
	In 2013, the Company held no derivative financial instruments. Beginning in 2014, the Company accounts for its derivative instruments as either assets or liabilities and carries them at fair value. The Company’s sole derivative (Note 6) has not been designated as a hedging instrument and is adjusted to fair value through current income.
Foreign Currency	'
	Foreign Currency
	During 2013, the Company had limited foreign currency exposure. With the acquisition of Okapi Sciences (Note 4) in 2014, the Company is exposed to effects of foreign currency from translation. Transactions in foreign currencies are translated into the relevant functional currency at the rate of exchange at the date of the transaction. Transaction gains and losses are recognized in arriving at loss from operations. The results of operations for subsidiaries, whose functional currency is not the U.S. Dollar, are translated into the U.S. Dollar at the average rates of exchange during the period, with the subsidiaries’ balance sheets translated at the rates accumulated at the balance sheet date. The cumulative effect of exchange rate movements is included in a separate component of other comprehensive income (loss) in the consolidated balance sheet. Gains and losses arising from intercompany foreign currency transactions are included in loss from operations unless the gains and losses arise from permanent differences in intercompany accounts. Gains and losses from permanent differences in intercompany accounts are included in a separate component of other comprehensive income (loss).
Comprehensive Loss	'
	Comprehensive Loss
	For the year ended December 31, 2013, there was no difference between net loss and comprehensive loss. During the first nine months of 2014, there were differences between net loss and comprehensive loss. The Company includes foreign currency translation adjustments related to the translation of foreign subsidiaries’ balance sheets, permanent differences in intercompany accounts and unrealized holding gains and losses on available-for-sale securities in comprehensive loss.
Goodwill	'
	Goodwill
	The Company completed its annual goodwill impairment testing during the third quarter of 2014.  The Company elected to bypass the qualitative assessment. The Company determined as of the testing date that it still consisted of one operating segment which is comprised of one reporting unit. In performing step one of the assessment,  the Company determined that its fair value, determined to be its market capitalization, was greater than its carrying value, determined to be stockholder’s equity. Based on this result, step two of the assessment was not required to be performed, and the Company determined there was no impairment of goodwill as of the testing date.
New Accounting Pronouncements	'
	New Accounting Pronouncements
	Revenue from Contracts with Customers
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued guidance on recognizing revenue in contracts with customers. The guidance affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards (e.g., insurance contracts or lease contracts). This guidance will supersede the revenue recognition requirements in topic, Revenue Recognition, and most industry-specific guidance. This guidance also supersedes some cost guidance included in subtopic, Revenue Recognition – Construction-Type and Production-Type Contracts. In addition, the existing requirements for the recognition of a gain or loss on the transfer of nonfinancial assets that are not in a contract with a customer (e.g., assets within the scope of topic, Property, Plant, and Equipment, and tangible assets within the scope of topic, Intangibles – Goodwill and Other) are amended to be consistent with the guidance on recognition and measurement (including the constraint on revenue) in this guidance.
	The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.
	These changes become effective for the Company on January 1, 2017 and early adoption is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is currently assessing the impact, if any, this new guidance will have on the Company’s financial condition, results of operations or cash flows.
	Development Stage Entities — Elimination of Certain Financial Reporting Requirements, Including an Amendment to Variable Interest Entities Guidance, Consolidations
	In June 2014, the FASB issued guidance that removes all incremental reporting requirements from GAAP for development stage entities, including the removal of the topic development stage entities. These changes eliminate the requirement to report inception-to-date information in the statements of income, cash flows, and shareholder equity. These changes become effective for the Company on January 1, 2015 and early adoption is permitted. The Company opted to adopt this guidance as of June 30, 2014. The adoption of this guidance resulted in decreased financial statement disclosures, but did not impact the Company’s financial condition, results of operations or cash flows.
	Disclosure of Uncertainties about an Entities Ability to Continue as a Going Concern
	In August 2014, the FASB issued guidance which requires management to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide disclosure in the footnotes under certain circumstances. This guidance is effective for fiscal years ending after December 15, 2016 with early adoption permitted. The Company does not expect that this guidance will have a material impact on its consolidated financial statements.
