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 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 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, 2017, generated an operating loss of approximately $ 6,029,000 The Company believes that its cash balance at June 30, 2017 is adequate to fund operations at budgeted levels into second quarter 2018. The Company’s ability to execute its operating plan beyond second quarter 2018 depends on its ability to obtain additional funding via the sale of equity and/or debt securities, a strategic transaction or otherwise. The Company plans to continue actively pursuing financing alternatives, but there can be no assurance that it will obtain the necessary funding, raising substantial doubt about the Company’s ability to continue as a going concern within one year of the date these financial statements are issued. The accompanying financial statements do not include any adjustments that might result from the outcome of this uncertainty. The accompanying condensed consolidated balance sheet as of December 31, 2016 has been derived from audited financial statements. The accompanying unaudited condensed consolidated balance sheet as of June 30, 2017, the condensed consolidated statements of operations for the three months and six months ended June 30, 2017 and 2016, the condensed consolidated statements of cash flows for the six months ended June 30, 2017 and 2016 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, 2017 and consolidated results of its operations for the three months and six months ended June 30, 2017 and 2016, and its cash flows for the six months ended June 30, 2017 and 2016. The results for the six months ended June 30, 2017 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, 2016, which was filed with the SEC on March 15, 2017. 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. 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, 2017 and 2016. In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill. The standard streamlines the methodology for calculating whether goodwill is impaired based upon whether the carrying amount of goodwill exceeds the reporting unit’s fair value. ASU 2017-04 applies to public business entities and those other entities that have goodwill reported in their financial statements and have not elected the private company alternative for the subsequent measurement of goodwill and is effective for annual and interim reporting periods beginning after December 15, 2019, with early adoption permitted. The Company does not expect that the adoption of this standard will have a material effect on its financial statements. - 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. Awards of stock that are not performance-based are valued at the fair market value on the date of the grant and are amortized over the service period of the award. 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 533,065 In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) which supersedes FASB ASC Topic 840, Leases (Topic 840) and provides principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than twelve months regardless of classification. Leases with a term of twelve months or less will be accounted for similar to existing guidance for operating leases. The standard is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted upon issuance. The Company is currently evaluating the method of adoption and the impact of adopting ASU 2016-02 on its results of operations, cash flows and financial position. |

Fair Value Disclosures [Abstract] | |
Fair Value Disclosures [Text Block] | 2. FAIR VALUE 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 issued warrants to purchase an aggregate of 82,500 27,500 16,250 38,750 In August 2014, as part of an underwritten public offering, the Company issued 494,315 June 30, 2017 Level 1 Level 2 Level 3 Fair Value Liabilities: February 2013 Public Offering Warrants $ $ $ 18,600 $ 18,600 August 2014 Warrants 101,000 101,000 Total $ $ 101,000 $ 18,600 $ 119,600 December 31, 2016 Level 1 Level 2 Level 3 Fair Value Liabilities: February 2013 Public Offering Warrants $ $ $ 27,125 $ 27,125 August 2014 Warrants 100,000 100,000 Total $ $ 100,000 $ 27,125 $ 127,125 In order to estimate the value of the February 2013 Public Offering Warrants considered to be derivative instruments, 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 rates, volatility, the contractual term of the warrants, future financing requirements and dividend rates. The future financing estimates are based on the Company’s estimates of anticipated cash requirements over the term of the warrants as well as the frequency of required financings based on its assessment of its historical financing trends and anticipated future events. Due to the nature of these inputs and the valuation technique utilized, these warrants are classified within the Level 3 hierarchy. Six Months Twelve Months June 30, December 31, Volatility 76 % 92.72-134 % Risk-free interest rate 1.21 % 0.53-1.15 % Expected life (years) 0.64 1.14-1.89 Dividend 0 % 0 % During fiscal year 2016, the Company had warrants outstanding for part of the year that were considered financial instruments. Those warrants were either extinguished or amended such that they were no longer considered financial instruments as of December 31, 2016, and were, therefore, not financial instruments during the three or six months ended June 30, 2017. Twelve Months Volatility 89.73 % Risk-free interest rate 1.65 % Expected life (years) 4.50 Dividend 0 % Six Months Twelve Months June 30, December 31, Beginning balance Fair value $ 27,125 $ 2,067,000 Reclassification to equity for warrants that are no longer derivative liabilities (1,392,429) Gain on derivatives resulting from change in fair value or extinguishment (8,525) (647,446) Ending balance Fair value $ 18,600 $ 27,125 In order to estimate the fair value of the August 2014 Warrants, the Company calculated the weighted average closing price for the trailing 10 day period with trades that ended on the balance sheet date. |

Pursuant to the Warrant Restructuring Agreement, the Company agreed with the holders of 2015 Series A warrants that upon the consummation of the 2016 Underwritten Offering, the exercise price of the 2015 Series A warrants would be reduced to the public offering price per share of the shares of common stock sold in this offering and that the warrants would be amended such that the exercise price would no longer be subject to adjustment in connection with future equity offerings we may undertake. In consideration of this amendment, the Company agreed to issue to each of those holders a new warrant to purchase an additional number of shares of common stock equal to twice the number of shares of common stock underlying the 2015 Series A Warrants held by them (the “Incremental Series A Warrants”). As a result, the 2015 Series A warrants and the Incremental Series A Warrants have an exercise price equal to $ 2.13 2016 Reverse Stock Split and Recapitalization At a special meeting held on February 8, 2016, the Company’s stockholders approved an amendment to the Company’s certificate of incorporation to effect a reverse split of the Company’s common stock at a ratio between 1:5 to 1:10 in order to ensure that adequate authorized but unissued shares would be available for anticipated future financings, and to satisfy requirements for the continued listing of the Company’s common stock on the NASDAQ Capital Market. In addition, the proposal approved by the stockholders provided that if the reverse split was effected, the number of shares of common stock that the Company is authorized to issue remained unchanged at 40,000,000 1-for-10 reverse split Common Stock Warrants Number of Shares Exercise Offering Outstanding Price Expiration Date November 2016 Public Offering Series C 4,172,850 $ 1.50 November 29, 2021 April 2016 Underwritten Registered Series A 3,626,942 $ 3.04 April 20,2021 October 2015 Incremental Series A 300,006 $ 2.13 October 20,2021 October 2015 Private Placement Series A 86,365 $ 2.13 April 1, 2021 October 2015 Offering Placement Agent 3,750 $ 28.30 October 1, 2020 August 2014 Public Offering (1) 504,019 $ 46.80 August 20, 2019 February 2013 Public Offering (1) 38,750 $ 1.50 (2) February 20, 2018 February 2013 Public Offering Placement Agents 3,854 $ 125.00 February 4, 2018 November 2012 Private Placement 5,000 $ 250.00 November 2, 2017 Total 8,741,536 (1) These warrants have a certain type of cash settlement feature or the exercise price for which the warrant may be exercised is subject to adjustment for “down-rounds” and the warrants have been accounted for as derivative instruments as described in Note 3, with the exception of 9,704 (2) Due to the issuance of common stock at $1.50 per share as part of the November 2016 Underwritten Offering, the remaining outstanding warrants issued as part of the February 2013 Public Offering were adjusted to reflect the revised exercise price of $1.50 each.

The fair value of each stock option 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. 2 Exercise prices for all grants made during the six months ended June 30, 2017 and 2016 were equal to the market value of the Company’s common stock on the date of grant.

There have been no options exercised during 2017. Shares of common stock issued upon the exercise of options are from authorized but unissued shares. Stock Grants During the three months ended June 30, 2017, the Company issued a total of 460,000 2.08 2.10 The unvested portion of the restricted stock grants is not considered to be outstanding for accounting purposes; therefore, the related shares are not included in the earnings per share calculation or the shares reported as outstanding on the balance sheet, as of or for the periods ended June 30, 2017. Note that such shares are considered outstanding from a legal perspective as of the date of grant. Unrecognized Compensation Cost As of June 30, 2017, there was approximately $ 1,740,000 408,000 736,000 524,000 72,000 12.42 2.37 |

Income Tax Disclosure [Abstract] | |
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, 2017 or 2016 because the Company has experienced losses on a tax basis since inception. Because of the 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 assets. 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 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 grants, stock options and warrants. Since there is a net loss attributable to common stockholders for the three months and six months ended June 30, 2017 and 2016, 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. Six Months Ended June 30, 2017 2016 Warrants 8,741,536 4,629,842 Stock options and grants 1,018,733 397,882 |

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 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, 2017 and 2016. In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill. The standard streamlines the methodology for calculating whether goodwill is impaired based upon whether the carrying amount of goodwill exceeds the reporting unit’s fair value. ASU 2017-04 applies to public business entities and those other entities that have goodwill reported in their financial statements and have not elected the private company alternative for the subsequent measurement of goodwill and is effective for annual and interim reporting periods beginning after December 15, 2019, with early adoption permitted. The Company does not expect that the adoption of this standard will have a material effect on its financial statements. |
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block] | Impairment of 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. Awards of stock that are not performance-based are valued at the fair market value on the date of the grant and are amortized over the service period of the award. 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. |

Lessee, Leases [Policy Text Block] | Leases In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) which supersedes FASB ASC Topic 840, Leases (Topic 840) and provides principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than twelve months regardless of classification. Leases with a term of twelve months or less will be accounted for similar to existing guidance for operating leases. The standard is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted upon issuance. The Company is currently evaluating the method of adoption and the impact of adopting ASU 2016-02 on its results of operations, cash flows and financial position. |

In addition, the proposal approved by the stockholders provided that if the reverse split was effected, the number of shares of common stock that the Company is authorized to issue remained unchanged at 40,000,000. The Company’s stockholders further authorized the board of directors to determine the ratio at which the reverse split would be effected by filing an appropriate amendment to the Company’s certificate of incorporation. The board of directors authorized the ratio of the reverse split and corresponding reduction in authorized shares on February 24, 2016, and effective at the close of business on March 4, 2016, the Company’s certificate of incorporation was amended to effect a 1-for-10 reverse split of the Company’s common stock (the “2016 Reverse Split”). All share and per share numbers included in these consolidated financial statements give effect to the 2016 Reverse Split. | |||||||
