Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Nature Of Business Organization and Going Concern Disclosure [Text Block] | Cellectar Biosciences, Inc. (the “Company”) is a clinical stage biopharmaceutical company focused on the discovery, development and commercialization of drugs for the treatment of cancer. The Company’s core objective is to leverage its proprietary phospholipid drug conjugate TM TM The Company is subject to a number of risks similar to those of other small pharmaceutical companies. Principal among these risks are the need to obtain additional financing necessary to fund future operations, dependence on key individuals, competition from substitute products and larger companies and the successful development and marketing of its products in a highly regulated environment. 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 its efforts toward research and development and has, during the three months ended March 31, 2018, generated an operating loss of approximately $ 3,454,000 The Company believes that its cash balance at March 31, 2018 is adequate to fund operations into early first quarter 2019. The Company’s ability to execute its operating plan beyond early first quarter 2019 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 to actively pursue 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, 2017 has been derived from audited financial statements. The accompanying unaudited condensed consolidated balance sheet as of March 31, 2018, the condensed consolidated statements of operations for the three months ended March 31, 2018 and 2017, the condensed consolidated statements of cash flows for the three months ended March 31, 2018 and 2017 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 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 March 31, 2018 and consolidated results of its operations and cash flows for the three months ended March 31, 2018 and 2017. The results for the three months ended March 31, 2018 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, 2017, which was filed with the SEC on March 21, 2018. 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. The Company accounts for cash that is restricted for other than current operations as restricted cash. Restricted cash at March 31, 2018 and December 31, 2017 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 three months ended March 31, 2018 and 2017. 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 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 494,315 and 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 in a similar fashion 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 July 2017, the FASB issued Accounting Standards Update (“ASU”) No. 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), Derivatives and Hedging (Topic 815). |

Fair Value Disclosures [Abstract] | |
Fair Value Disclosures [Text Block] | 2. FAIR VALUE In accordance with 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 February 20, 2018 In August 2014, as part of an underwritten public offering, the Company issued 494,315 March 31, 2018 Level 1 Level 2 Level 3 Fair Value Liabilities: August 2014 Warrants $ $ 132,000 $ $ 132,000 Total $ $ 132,000 $ $ 132,000 December 31, 2017 Level 1 Level 2 Level 3 Fair Value Liabilities: February 2013 Public Offering Warrants $ $ $ 5,050 $ 5,050 August 2014 Warrants 100,000 100,000 Total $ $ 100,000 $ 5,050 $ 105,050 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. These warrants are classified within the Level 3 hierarchy because of the nature of the inputs and the valuation technique utilized. Three Months Twelve Months Volatility N/A 76-118 % Risk-free interest rate N/A 1.03-1.39 % Expected life (years) N/A 0.14-0.89 Dividend N/A 0 % Three Months Twelve Months Beginning balance Fair value $ 5,050 $ 27,125 (Gain) on derivatives resulting from change in fair value or extinguishment (5,050) (22,075) Ending balance Fair value $ $ 5,050 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. |

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 three months ended March 31, 2018 or 2017 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 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 [Text Block] | 7. NET LOSS PER SHARE Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period. Diluted net income per share for the three months ended March 31, 2018 is computed by dividing net income 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, non-vested restricted stock and warrants. Since there is a net loss attributable to common stockholders for the three months ended March 31, 2018, the inclusion of common stock equivalents in the computation for that period would be antidilutive.

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 494,315 and 533,065 |
Lessor, 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 in a similar fashion 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. |
New Accounting Pronouncements, Policy [Policy Text Block] | Recent Accounting Pronouncements - In July 2017, the FASB issued Accounting Standards Update (“ASU”) No. 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), Derivatives and Hedging (Topic 815). |
