Description of Business and Development Stage Activities	3 Months Ended
	Mar. 31, 2012
Development Stage Enterprises [Abstract]
Development Stage Enterprise General Disclosures [Text Block]	Description of Business and Development Stage Activities On June 4, 1999, NewLink Genetics Corporation (“NewLink”) was incorporated as a Delaware corporation. NewLink was formed for the purpose of developing treatments for cancer and other diseases. NewLink initiated operations in April of 2000, which primarily consist of research and development. In 2005, NewLink created a wholly owned subsidiary, BioProtection Systems Corporation (“BPS”). NewLink contributed certain licensing agreements and other intangible assets for BPS to create vaccines against potential biological terror threats. NewLink and BPS (together referred to herein as the “Company”) are development stage enterprises and are devoting substantially all of their efforts toward research and development. The Company has never earned revenue from sales of its drugs under development. The Company has, from June 4, 1999 (inception) through March 31, 2012 generated a cumulative deficit of $86.3 million. The accompanying financial statements have been prepared assuming the Company will continue as a going concern. The Company received $37.6 million as a result of the closing of the initial public offering of the Company's common stock (“IPO”) on November 16, 2011, which is expected to fund operations through 2013. The generation of additional financing may be necessary for the Company to continue operations in the future. There can be no assurance, however, that such financing will be available on terms acceptable to the Company or at all.

- Definition

The entire disclosure for all or part of the detailed information required for development stage enterprises. The information may also be disclosed on an element-by-element basis. Information may include an identification of the current or prior year financial statements of the entity, its development stage subsidiaries, or its investees as those of one or more development stage enterprises; a description of the nature of the development stage activities in which each enterprise is engaged; and in the first fiscal year in which each enterprise is no longer considered a development stage enterprise, a statement that in prior years the enterprise had been in the development stage.

Significant Accounting Policies

3 Months Ended

Mar. 31, 2012

Accounting Policies [Abstract]

Significant Accounting Policies [Text Block]

Significant Accounting Policies


(a)	Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (U.S. 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.


(b)	Principles of Consolidation

The consolidated financial statements include the financial statements of NewLink and BPS. All significant intercompany balances and transactions have been eliminated in consolidation.


(c)	Financial Instruments and Concentrations of Credit Risk

The fair values of cash and cash equivalents, certificates of deposit, prepaid expenses, receivables, accounts payable, and accrued liabilities, which are recorded at cost, approximate fair value based on the short-term nature of these financial instruments. Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, and certificates of deposit. Cash and cash equivalents are held by financial institutions and are federally insured up to certain limits. At times, the Company’s cash and cash equivalents balance exceeds the federally insured limits. To limit the credit risk, the Company invests its excess cash primarily in high quality securities such as money market funds. The fair value and carrying value of notes payable, capital lease obligations, and the royalty obligation payable was $7.1 million and $7.2 million as of March 31, 2012 and December 31, 2011, respectively.


(d)	Recently Adopted Accounting Pronouncements

In June 2011, the Financial Accounting Standards Board (FASB) issued new accounting guidance which revised the manner in which companies present comprehensive income in their financial statements. The new guidance removed the presentation options previously allowed and requires companies to report components of comprehensive income as part of the consolidated statement of income or as a separate consolidated statement of comprehensive income. The revised guidance did not change the items that must be reported in other comprehensive income. The guidance was effective for the Company on January 1, 2012. Comprehensive income consists of net income and other comprehensive income (loss). Other comprehensive income (loss) refers to revenues, expenses, gains and losses that are not included in net income, but rather are recorded directly in stockholders’ equity. The Company adopted this guidance on January 1, 2012. During the three months ended March 31, 2012 and 2011 there were no amounts recorded directly in stockholders’ equity and therefore there was no difference between net income and comprehensive income for these two respective periods.

Long-Term Debt Conversion to Royalty Obligation [Abstract]
Long-term Debt [Text Block]	Long-Term Debt Conversion to Royalty Obligation March 2005 Iowa Department of Economic Development Loan In March 2005, the Company entered into a $6.0 million forgivable loan agreement with the Iowa Department of Economic Development, or the IDED. Under the agreement, in the absence of default, there were no principal or interest payments due until the completion date for the project. The balance outstanding under the loan agreement was $6.0 million as of December 31, 2011. The agreement provided the Company with financial assistance for research and product development activities at its Iowa State University Research Park facility. Additionally, under the agreement, the Company was obligated to pay a minimum of 0.25% royalties on all gross revenues of any products the Company brings to market with a cumulative maximum royalty amount due of $3.2 million. Substantially all of the Company's assets were pledged to secure this loan. On March 27, 2012 the Company entered into a settlement agreement with the Iowa Economic Development Authority ("IEDA") as the successor organization to IDED. Under the terms of the settlement agreement the Company agreed to pay a 0.5% royalty on future product sales up to a cap of $6.8 million in exchange for IEDA’s release of the Company's job creation and project expenditure obligations and their release of the security interest in substantially all of the Company's assets. As no payments are expected in the next 12 months, the entire accrued royalty obligation of $6.0 million is considered long-term. There were no other changes in the terms of the Company's other long-term debt agreements since December 31, 2011 as reported in the Company's Annual Report on Form 10-K as amended.

Common Stock Equity Incentive Plan

Share-based employee compensation expense for the three months ended March 31, 2012 and 2011 and since inception was $736,000, $368,000 and $5.8 million, respectively, and is allocated between research and development and general and administrative expenses within the consolidated statements of operations. As of March 31, 2012, the total compensation cost related to non-vested option awards not yet recognized was $5.2 million and the weighted average period over which it is expected to be recognized was 1.9 years.

The following table summarizes the stock option activity for the three months ended March 31, 2012:



	Number of options		Weighted average exercise price		Weighted average remaining contractual term (years)
Outstanding at beginning of period	3,515,051		$	3.51
Options granted	534,281		6.87
Options exercised	(70,789	)	1.90
Options forfeited	(8,654	)	5.91

Outstanding at end of period	3,969,889		$	3.98	7.8
Options exercisable at end of period	2,383,389		$	2.96	7.1

As of March 31, 2012, there were an additional 597,027 shares reserved for future issuance under the Company's employee benefit plans.

During the three months ending March 31, 2012 the Company issued stock awards of 10,000 shares of common stock with a fair value of $68,700.

The following table summarizes the assumptions used to estimate the fair value of those stock options granted during the three months ended March 31, 2012 using a Black-Scholes valuation model:

Income Taxes	3 Months Ended
Income Taxes	Mar. 31, 2012
Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes The Company incurred no income tax expense for the three months ended March 31, 2012 and 2011 or since inception. Income tax expense differs from the amount that would be expected after applying the statutory U.S. federal income tax rate primarily due to changes in the valuation allowance for deferred taxes. The valuation allowance for deferred tax assets as of March 31, 2012 and December 31, 2011 was $19.8 million and $18.9 million, respectively. The net change in the total valuation allowance for the three months ended March 31, 2012 and 2011 was an increase of $961,000 and $1.1 million, respectively. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected taxable income, and tax planning strategies in making this assessment. Valuation allowances have been established for the entire amount of the net deferred tax assets as of March 31, 2012 and December 31, 2011, due to the uncertainty of future recoverability.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Net Loss per Common Share

Earnings Per Share [Abstract]

Earnings Per Share [Text Block]

Net Loss per Common Share

Basic net loss per share is calculated by dividing the net loss attributable to common stockholders by the weighted average number of common shares outstanding for the period, without consideration of common stock equivalents. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted average number of common share equivalents outstanding for the period determined using the treasury-stock method. For purposes of this calculation, preferred stock, stock options and warrants are considered to be common stock equivalents and are only included in the calculation of diluted net loss per share when their effect is dilutive.

The following table presents the computation of basic and diluted net loss per common share (in thousands, except per share data):



	Three Months Ended March 31,
	2012			2011
Numerator
Net loss attributable to common stockholders	$	(4,842	)	$	(3,897	)
Denominator
Weighted-average common shares outstanding	20,613			3,636
Basic and diluted net loss per common share	$	(0.23	)	$	(1.07	)

The numerator was not adjusted for the stock dividend paid on the Company’s Series AA preferred stock as the impact is not material. Potentially dilutive securities not included in the calculation of diluted net loss per common share because to do so would be anti-dilutive are as follows (in common equivalent shares):



	As of March 31,
	2012	2011
Preferred stock (1)	—	9,870,527
Common stock options	3,969,889	2,992,810
	3,969,889	12,863,337

_________________________________

(1) Amounts for the Company’s Series BB, C, D and E conversions are computed based on the IPO price of $7.00 per share.
