Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Nature Of Business Organization and Going Concern Disclosure [Text Block] | 1. NATURE OF BUSINESS, ORGANIZATION AND GOING CONCERN Cellectar Biosciences, Inc. (the “Company”) is a biopharmaceutical company developing compounds for the treatment, diagnosis and imaging of cancer. The Company’s headquarters are located in Madison, Wisconsin. The Company is subject to a number of risks similar to those of other small pharmaceutical companies. Principal among these risks are dependence on key individuals, competition from substitute products and larger companies, the successful development and marketing of its products in a highly regulated environment and the need to obtain additional financing necessary to fund future operations. The accompanying financial statements have been prepared on a basis that assumes that the Company will continue as a going concern and that contemplates the continuity of operations, realization of assets and the satisfaction of liabilities and commitments in the normal course of business. The Company has devoted substantially all of its efforts toward research and development and has, during the six months ended June 30, 2015, generated a net loss of approximately $ 4,588,000 The accompanying condensed consolidated balance sheet as of December 31, 2014 has been derived from audited financial statements. The accompanying unaudited condensed consolidated balance sheet as of June 30, 2015, the condensed consolidated statements of operations for the three months and six months ended June 30, 2015 and 2014, the condensed consolidated statements of cash flows for the six months ended June 30, 2015 and 2014 and the related interim information contained within the notes to the condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions, rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, they do not include all of the information and the notes required by U.S. GAAP for complete financial statements. In the opinion of management, the unaudited interim condensed consolidated financial statements reflect all adjustments which are of a nature necessary for the fair presentation of the Company’s consolidated financial position at June 30, 2015 and consolidated results of its operations for the three months and six months ended June 30, 2015 and 2014, and its cash flows for the six months ended June 30, 2015 and 2014. The results for the six months ended June 30, 2015 are not necessarily indicative of future results. These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and related notes thereto included in the Company’s Form 10-K for the fiscal year ended December 31, 2014, which was filed with the SEC on March 24, 2015, as amended by Form 10-K/A filed with the SEC on May 20, 2015. The consolidated financial statements include the accounts of the Company and the accounts of its wholly-owned subsidiary. All significant intercompany accounts and transactions have been eliminated in consolidation. The Company accounts for cash that is restricted for other than current operations as restricted cash. Restricted cash at June 30, 2015 and December 31, 2014 consisted of a certificate of deposit of $ 55,000 Goodwill is not amortized, but is required to be evaluated for impairment annually or whenever events or changes in circumstances suggest that the carrying value of an asset may not be recoverable. The Company evaluates goodwill for impairment annually in the fourth fiscal quarter and additionally on an interim basis if an event occurs or there is a change in circumstances, such as a decline in the Company’s stock price or a material adverse change in the business climate, which would more likely than not reduce the fair value of the reporting unit below its carrying amount. No such event or change in circumstances occurred; therefore no changes in goodwill were made during the six months ended June 30, 2015 and 2014. - Lived Assets The Company uses the Black-Scholes option-pricing model to calculate the grant-date fair value of stock option awards. The resulting compensation expense, net of expected forfeitures, for awards that are not performance-based is recognized on a straight-line basis over the service period of the award, which is generally three years for stock options. For stock options with performance-based vesting provisions, recognition of compensation expense, net of expected forfeitures, commences if and when the achievement of the performance criteria is deemed probable. The compensation expense, net of expected forfeitures, for performance-based stock options is recognized over the relevant performance period. Non-employee stock-based compensation is accounted for in accordance with the guidance of Financial Accounting Standards Board Accounting Standards Codification (“FASB ASC”) Topic 505, Equity. The guidance under FASB ASC Topic 825, Financial Instruments The Company generally does not use derivative instruments to hedge exposures to cash flow or market risks. However, certain warrants to purchase common stock that do not meet the requirements for classification as equity, in accordance with the Derivatives and Hedging Topic of the FASB ASC, are classified as liabilities. In such instances, net-cash settlement is assumed for financial reporting purposes, even when the terms of the underlying contracts do not provide for a net-cash settlement. These warrants are considered derivative instruments because the agreements contain a certain type of cash settlement feature, “down-round” provisions whereby the number of shares for which the warrants are exercisable and/or the exercise price of the warrants is subject to change in the event of certain issuances of stock at prices below the then-effective exercise price of the warrants. The number of shares issuable under such warrants was 5,494,388 In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern ASU 2014-15 applies to all entities and is effective for annual and interim reporting periods ending after December 15, 2016, with early adoption permitted. The Company does not expect that the adoption of this standard will have a material effect on its financial statements. |

Fair Value Disclosures [Abstract] | |
Fair Value Disclosures [Text Block] | In accordance with the Fair Value Measurements and Disclosures Topic of the FASB ASC 820, the Company groups its financial assets and financial liabilities generally measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. · Level 1: Input prices quoted in an active market for identical financial assets or liabilities. · Level 2: Inputs other than prices quoted in Level 1, such as prices quoted for similar financial assets and liabilities in active markets, prices for identical assets and liabilities in markets that are not active or other inputs that are observable or can be corroborated by observable market data. · Level 3: Input prices quoted that are significant to the fair value of the financial assets or liabilities which are not observable or supported by an active market. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The Company had issued warrants to purchase 1,365 550,000 4,943,023 June 30, 2015 Level 1 Level 2 Level 3 Fair Value Liabilities: July 2010 Warrants $ $ 100 $ $ 100 February 2013 Public Offering Warrants 935,000 935,000 August 2014 Warrants 3,949,440 3,949,440 Total $ $ 3,949,540 $ 935,000 $ 4,884,540 December 31, 2014 Level 1 Level 2 Level 3 Fair Value Liabilities: July 2010 Warrants $ $ 999 $ $ 999 February 2013 Public Offering Warrants 1,127,500 1,127,500 August 2014 Warrants 4,048,416 4,048,416 Total $ $ 4,049,415 $ 1,127,500 $ 5,176,915 In order to estimate the fair value of the July 2010 Warrants, the Company uses the Black-Scholes option pricing model and assumptions that consider, among other variables, the fair value of the underlying stock, risk-free interest rate, volatility, expected life and dividend rates. Assumptions used are generally consistent with those disclosed for stock-based compensation (see Note 5). In order to estimate the value of the February 2013 Public Offering Warrants considered to be derivative instruments as of June 30, 2015, the Company uses a modified option-pricing model together with assumptions that consider, among other variables, the fair value of the underlying stock, risk-free interest rate of .88%, volatility of 90 2.64 The assumptions used to estimate the value of the February 2013 Public Offering Warrants as of December 31, 2014 include the fair value of the underlying stock, risk free interest rates ranging from 1.07 2.63 100 115 3.14 3.89 Twelve Months Six Months Ended Ended June 30, December 31, 2015 2014 Beginning balance Fair value $ 1,127,500 $ 3,355,000 Gain on derivatives resulting from change in fair value (192,500) (2,227,500) Ending balance Fair value $ 935,000 $ 1,127,500 To estimate the fair value of the August 2014 Warrants, the Company calculated the weighted average closing price of the August 2014 Warrants for the 10 trading day period that ended on the balance sheet date. |

These warrants are considered derivative instruments because the agreements contain a certain type of cash settlement feature; therefore, the Company determined that these warrants meet the requirements for classification as a liability. In conjunction with the August 2014 Underwritten Offering, the Company’s common stock and the warrants issued in the offering were listed on the NASDAQ Capital Market.

The fair value of each stock award is estimated on the grant date using the Black-Scholes option-pricing model. The estimated fair value of employee stock options is amortized to expense using the straight-line method over the vesting period. The estimated fair value of the non-employee options is amortized to expense over the period during which a non-employee is required to provide services for the award (usually the vesting period). Volatility. The Company estimates volatility based on an average of (1) the Company’s historical volatility since its common stock has been publicly traded and (2) review of volatility estimates of publicly held drug development companies with similar market capitalizations. Risk-free interest rate . The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant commensurate with the expected term assumption. Expected term . The expected term of stock options granted is based on an estimate of when options will be exercised in the future. The Company applied the simplified method of estimating the expected term of the options, as described in the SEC’s Staff Accounting Bulletins 107 and 110, as the historical experience is not indicative of the expected behavior in the future. The expected term, calculated under the simplified method, is applied to groups of stock options that have similar contractual terms. Using this method, the expected term is determined using the average of the vesting period and the contractual life of the stock options granted. The Company applied the simplified method to non-employees who have a truncation of term based on termination of service and utilizes the contractual life of the stock options granted for those non-employee grants which do not have a truncation of service. Forfeitures. The Company records stock-based compensation expense only for those awards that are expected to vest. A forfeiture rate is estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from initial estimates. An annual forfeiture rate of 2 0 Six Months Six Months Ended Ended June 30, 2015 June 30, 2014 Volatility 105-107 % 108 % Risk-free interest rate 1.70-1.95 % 1.76 % Expected life (years) 6.0 6.0 Dividend 0 % 0 % Weighted-average exercise price $ 2.65-2.69 $ 7.40 Weighted-average grant-date fair value $ 2.17-2.20 $ 6.20 Exercise prices for all grants made during the six months ended June 30, 2015 were equal to the market value of the Company’s common stock on the date of grant.

Income Tax Disclosure [Text Block] | 6. INCOME TAXES The Company accounts for income taxes in accordance with the liability method of accounting. Deferred tax assets or liabilities are computed based on the difference between the financial statement and income tax basis of assets and liabilities, and net operating loss carryforwards, (NOLs) using the enacted tax rates. Deferred income tax expense or benefit is based on changes in the asset or liability from period to period. The Company did not record a provision or benefit for federal, state or foreign income taxes for the six months ended June 30, 2015 or 2014 because the Company has experienced losses on a tax basis since inception. Because of the limited operating history, continuing losses and uncertainty associated with the utilization of the NOLs in the future, management has provided a full allowance against the value of its gross deferred tax asset. The Company also accounts for the uncertainty in income taxes related to the recognition and measurement of a tax position taken or expected to be taken in an income tax return. The Company follows the applicable accounting guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition related to the uncertainty in income tax positions. No uncertain tax positions have been identified. |

Earnings Per Share [Abstract] | |
Earnings Per Share [Text Block] | 7. NET LOSS PER SHARE Basic net loss per share is computed by dividing net loss by the weighted average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by dividing net loss, as adjusted, by the sum of the weighted average number of shares of common stock and the dilutive potential common stock equivalents then outstanding. Potential common stock equivalents consist of stock options and warrants. Since there is a net loss attributable to common stockholders for the three and six months ended June 30, 2015 and 2014, the inclusion of common stock equivalents in the computation for those periods would be antidilutive. Accordingly, basic and diluted net loss per share is the same for all periods presented.

NATURE OF BUSINESS, ORGANIZAT15
NATURE OF BUSINESS, ORGANIZATION AND GOING CONCERN (Policies) | 6 Months Ended |
Jun. 30, 2015 | |
Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Consolidation, Policy [Policy Text Block] | Principles of Consolidation The consolidated financial statements include the accounts of the Company and the accounts of its wholly-owned subsidiary. All significant intercompany accounts and transactions have been eliminated in consolidation. |
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block] | Restricted Cash The Company accounts for cash that is restricted for other than current operations as restricted cash. Restricted cash at June 30, 2015 and December 31, 2014 consisted of a certificate of deposit of $ 55,000 |
Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block] | Goodwill Goodwill is not amortized, but is required to be evaluated for impairment annually or whenever events or changes in circumstances suggest that the carrying value of an asset may not be recoverable. The Company evaluates goodwill for impairment annually in the fourth fiscal quarter and additionally on an interim basis if an event occurs or there is a change in circumstances, such as a decline in the Company’s stock price or a material adverse change in the business climate, which would more likely than not reduce the fair value of the reporting unit below its carrying amount. No such event or change in circumstances occurred; therefore no changes in goodwill were made during the six months ended June 30, 2015 and 2014. |
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block] | Long - Lived Assets |
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block] | Stock-Based Compensation The Company uses the Black-Scholes option-pricing model to calculate the grant-date fair value of stock option awards. The resulting compensation expense, net of expected forfeitures, for awards that are not performance-based is recognized on a straight-line basis over the service period of the award, which is generally three years for stock options. For stock options with performance-based vesting provisions, recognition of compensation expense, net of expected forfeitures, commences if and when the achievement of the performance criteria is deemed probable. The compensation expense, net of expected forfeitures, for performance-based stock options is recognized over the relevant performance period. Non-employee stock-based compensation is accounted for in accordance with the guidance of Financial Accounting Standards Board Accounting Standards Codification (“FASB ASC”) Topic 505, Equity. |
Fair Value of Financial Instruments, Policy [Policy Text Block] | Fair Value of Financial Instruments The guidance under FASB ASC Topic 825, Financial Instruments |
Derivatives, Policy [Policy Text Block] | Derivative Instruments The Company generally does not use derivative instruments to hedge exposures to cash flow or market risks. However, certain warrants to purchase common stock that do not meet the requirements for classification as equity, in accordance with the Derivatives and Hedging Topic of the FASB ASC, are classified as liabilities. In such instances, net-cash settlement is assumed for financial reporting purposes, even when the terms of the underlying contracts do not provide for a net-cash settlement. These warrants are considered derivative instruments because the agreements contain a certain type of cash settlement feature, “down-round” provisions whereby the number of shares for which the warrants are exercisable and/or the exercise price of the warrants is subject to change in the event of certain issuances of stock at prices below the then-effective exercise price of the warrants. The number of shares issuable under such warrants was 5,494,388 |
Going Concern Disclosure [Policy Text Block] | In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern ASU 2014-15 applies to all entities and is effective for annual and interim reporting periods ending after December 15, 2016, with early adoption permitted. The Company does not expect that the adoption of this standard will have a material effect on its financial statements. |
