NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. NATURE OF BUSINESS, ORGANIZATION AND GOING CONCERN

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 (PDCs^TM) delivery platform to develop PDCs that specifically target cancer cells to deliver improved efficacy and better safety as a result of fewer off-target effects.

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 and suppliers, competition from substitute products and larger companies and the successful development and marketing of its products in a highly regulated environment.

The Company believes that it has sufficient liquidity to fund operations through 12 months from the filing of these financial statements, therefore, 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. However, its future results of operations and ability to obtain additional capital involve significant risks and uncertainties. The Company has devoted substantially all of its efforts toward research and development and has, during the nine months ended September 30, 2018, generated an operating loss of approximately $9,446,000. The Company expects that it will continue to generate operating losses for the foreseeable future.

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 September 30, 2018, the condensed consolidated statements of operations for the three months and nine months ended September 30, 2018 and 2017, the condensed consolidated statements of stockholders’ equity for the nine months ended September 30, 2018 and 2017 and the condensed consolidated statements of cash flows for the nine months ended September 30, 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 of the information and the notes required by U.S. GAAP for complete financial statements, although the company believes that the disclosures made are adequate to make the information not misleading. 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 September 30, 2018 and consolidated results of its operations for the three months and nine months ended September 30, 2018 and 2017, the consolidated changes in its stockholders’ equity for the nine months ended September 30, 2018 and 2017 and its cash flows for the nine months ended September 30, 2018 and 2017. The results for the nine months ended September 30, 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.

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.

Reclassifications — Certain amounts in prior periods have been reclassified to conform to the current year presentation. Such classifications did not have a material effect on the Company’s financial condition or results of operations as previously reported.

Restricted Cash — The Company accounts for cash that is restricted for other than current operations as restricted cash. Restricted cash at September 30, 2018 and December 31, 2017 consisted of a certificate of deposit of $55,000 required under the Company’s lease agreement for its Madison, Wisconsin facility.

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 nine months ended September 30, 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.

Impairment of Long-Lived Assets — Long-lived assets other than goodwill consist primarily of fixed assets, which we periodically evaluate for potential impairment. Whenever events or circumstances change, an assessment is made as to whether there has been an impairment in the value of long-lived assets by determining whether projected undiscounted cash flows generated by the applicable asset exceed its net book value as of the assessment date. No such event or change in circumstances occurred; therefore, no such impairment occurred during the nine months ended September 30, 2018 and 2017.

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. As such, the Company recognizes expense based on the estimated fair value of options granted to non-employees over their vesting period, which is generally the period during which services are rendered and deemed completed by such non-employees.

Fair Value of Financial Instruments — The guidance under FASB ASC Topic 825, Financial Instruments, requires disclosure of the fair value of certain financial instruments. Financial instruments in the accompanying financial statements consist of cash equivalents, accounts payable and long-term obligations. The carrying amount of cash equivalents and accounts payable approximate their fair value due to their short-term nature. The carrying value of remaining long-term obligations, including the current portion, approximates fair value because the fixed interest rate approximates current market interest rates available on similar instruments.

Derivative Instruments — The Company 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 49,425 and 53,306 at September 30, 2018 and December 31, 2017, respectively. The primary underlying risk exposure pertaining to the warrants is the change in fair value of the underlying common stock. Such financial instruments are initially recorded at fair value with subsequent changes in fair value recorded as a component of gain or loss on derivatives on the consolidated statements of operations in each reporting period. If these instruments subsequently meet the requirements for equity classification, the Company reclassifies the fair value to equity. At September 30, 2018 and December 31, 2017, these warrants represented the only outstanding derivative instruments issued or held by the Company.

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.

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). The amendments in Part I of this update change the classification analysis of certain equity-linked financial instruments (or embedded features) with down round features. When determining whether certain financial instruments should be classified as liabilities or equity instruments, a down round feature no longer precludes equity classification when assessing whether the instrument is indexed to an entity’s own stock. The amendments also clarify existing disclosure requirements for equity-classified instruments. As a result, a freestanding equity-linked financial instrument (or embedded conversion option) no longer would be accounted for as a derivative liability at fair value as a result of the existence of a down round feature. 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 2017-11 on its results of operations, cash flows and financial position.

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.

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 8,250 common shares in a February 2013 public offering (the “February 2013 Public Offering Warrants”). On February 20, 2014, 2,750 of the February 2013 Public Offering Warrants expired. On May 20, 2016, 1,625 warrants were exercised. The remaining 3,875 warrants expired on February 20, 2018.

In August 2014, as part of an underwritten public offering, the Company issued 49,425 warrants to purchase common stock (the “August 2014 Warrants”). The August 2014 Warrants are listed on the Nasdaq Capital Market under the symbol “CLRBW,” however, there are certain periods where trading volume is low; therefore, they are classified as Level 2 within the hierarchy.

The following tables set forth the Company’s financial instruments carried at fair value using the lowest level of input applicable to each financial instrument as of September 30, 2018 and December 31, 2017:

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. As a result of the nature of these inputs and the valuation technique utilized, these warrants are classified within the Level 3 hierarchy.

The following table summarizes the modified option-pricing assumptions used:

The following table summarizes the changes in the fair market value of the Company’s warrants which are classified within the Level 3 fair value hierarchy:

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.

3. STOCKHOLDERS’ EQUITY

July 2018 Public Offering

On July 31, 2018, the Company sold 1,355,000 shares of common stock, 1,114 shares of Series C Convertible Preferred Stock (the “Series C Preferred Stock”) convertible into 2,785,000 shares of common stock and Series E warrants to purchase 4,140,000 shares of common stock. The public offering price of a share of common stock together with a Series E warrant to purchase one share of common stock was $4.00. The public offering price of a share of Series C Preferred Stock, each of which is convertible into 2,500 shares of Common Stock, together with a Series E warrant to purchase 2,500 shares of common stock was $10,000. The Series E warrants have an exercise price of $4.00 per share and are exercisable until July 31, 2023. Gross offering proceeds to the Company were $16.56 million, with net proceeds to the Company of approximately $15.03 million after deducting underwriting discounts and commissions and related offering expenses.

In order to account for the July 2018 public offering, the Company allocated the proceeds to the common stock, the Series C Preferred Stock and the Series E warrants on a relative fair value basis. Then using the effective conversion price of the Series C Preferred Stock, the Company determined that there was a beneficial conversion feature (“BCF”) of $2,241,795. The BCF did not impact total Stockholders’ Equity but is reflected as a deemed dividend in arriving at net loss attributable to common stockholders.

The Series C Preferred Stock includes a beneficial ownership blocker but has no dividend rights (except to the extent that dividends are also paid on the common stock), liquidation preference or other preferences over common stock, and subject to limited exceptions, has no voting rights. As of September 30, 2018, 456 shares of Series C Preferred Stock were converted into 1,140,000 shares of common stock.

Reverse Stock Split

At a special meeting held on July 12, 2018, our stockholders approved an amendment to our certificate of incorporation to affect a reverse split of our common stock at a ratio between 1:5 to 1:10 and authorized the Board to determine the ratio at which the reverse split would be. The Board authorized the ratio of the reverse split, and effective at the close of business on July 16, 2018, the Company implemented a 1-for-10 reverse stock split of its outstanding common stock. The accompanying condensed consolidated financial statements and accompanying notes to the condensed consolidated financial statements give retroactive effect to the reverse stock split for all periods presented. The shares of common stock that the Company is authorized to issue remains unchanged at 80,000,000 and the par value remains at $0.00001 per share. Accordingly, stockholders’ equity reflects the reverse stock split by reclassifying from common stock to additional paid-in capital an amount equal to the par value of the decreased shares resulting from the reverse stock split.

Authorized Share Increase

At a special meeting held on September 12, 2017, the Company’s stockholders approved the ratification of the approval of the Certificate of Amendment to our Certificate of Incorporation to increase the number of authorized shares by 40,000,000 to 80,000,000 which was previously approved by the Company’s stockholders at our annual meeting of stockholders held on May 31, 2017.

October 2017 Registered Direct Offering

On October 12, 2017, the Company closed on a registered direct offering (the “October 2017 Registered Direct Offering”), priced at-the-market, of 195,438 shares of its common stock and 41.0412949 shares of its Series B Preferred Stock. The Series B Preferred Stock was offered at $100,000 per share and is immediately convertible into approximately 5,337 shares of common stock for a total of 219,037 shares upon conversion at a price of $18.7375 per share. The common stock was offered at $18.7375 per share. Gross offering proceeds to the Company were $7.76 million. In a concurrent private placement, the Company offered purchasers in the registered direct offering Series D warrants to purchase an aggregate of 310,856 shares of common stock, or 0.75 shares of common stock for each share of common stock purchased directly or issuable upon conversion of shares of preferred stock. The Series B Preferred Stock is non-voting, has no dividend rights (except to the extent dividends are also paid on common stock), liquidation preference, or other preferences over common stock. The Series D warrants are immediately exercisable at an exercise price of $17.80 per share and expire seven years from the closing. The Series D warrants, which are callable by the Company under certain circumstances, will not trade. Gross proceeds were approximately $7.8 million with net proceeds to the Company of approximately $7.1 million.

In order to account for the October 2017 Registered Direct Offering, the Company allocated the proceeds to the common stock, the Series B Preferred Stock and the Series D warrants on a relative fair value basis. Then using the effective conversion price of the Series B Preferred Stock, the Company determined that there was a beneficial conversion feature of $1,448,945.

On or prior to December 31, 2017, 23 shares of Series B Preferred Stock issued in the October 2017 Registered Direct Offering were converted into 122,751 shares of common stock. During the nine months ended September 30, 2018 the remaining 18 shares of Series B Preferred Stock were converted into 96,284 shares of common stock.

Common Stock Warrants

The following table summarizes information with regard to outstanding warrants to purchase common stock as of September 30, 2018.

4. STOCK-BASED COMPENSATION

Accounting for Stock-Based Compensation

The following table summarizes amounts charged to expense for stock-based compensation related to employee and director stock grants and stock option grants and recorded in connection with stock options granted to non-employee consultants:

Assumptions Used In Determining Fair Value for Stock Options

Valuation and amortization method. 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.  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% was applied to all unvested options for the nine months ended September 30, 2018 and for the year ended December 31, 2017. Ultimately, the actual expense recognized over the vesting period will be for only those shares that vest.

Dividends. The Company has not historically recorded dividends related to stock options.

Exercise prices for all grants made during the nine months ended September 30, 2018 and 2017 were equal to the market value of the Company’s common stock on the date of grant.

Stock Option Activity

A summary of stock option activity is as follows:

The aggregate intrinsic value of options outstanding is calculated based on the positive difference between the estimated per-share fair value of common stock at the end of the respective period and the exercise price of the underlying options. There have been no options exercised during 2018. Shares of common stock issued upon the exercise of options are from authorized but unissued shares.

As of September 30, 2018, there was approximately $753,000 of total unrecognized compensation cost related to unvested stock-based compensation arrangements. Of this total amount, the Company expects to recognize approximately $170,000, $480,000, $96,000 and $7,000 during 2018, 2019, 2020 and 2021 respectively. The Company’s expense estimates are based upon the expectation that all unvested stock grants and stock options will vest in the future, less the forfeiture rate discussed above. The weighted-average grant-date fair value of vested and unvested stock grants and stock options outstanding at September 30, 2018 was $45.67 and $21.34, respectively.

During the nine months ended September 30, 2018, the Company granted a total of 8,000 options.

Restricted Stock Grants. During 2017, the Company granted 46,000 shares of restricted common stock with a weighted average grant date fair value of $21.00. The shares vest annually over a three year period. As of December 31, 2017, 38,000 shares of restricted common stock were outstanding. There were no restricted stock grants issued during the nine months ended September 30, 2018. A summary of restricted stock activity is as follows:

5. NOTES PAYABLE

During the three months ended March 31, 2017, the two loans with initial principal amounts totaling $450,000 from the Wisconsin Economic Development Corporation, dated September 15, 2010, were paid in full.

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 nine months ended September 30, 2018 or 2017 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 de-recognition, 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.

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 nine months ended September 30, 2018 and 2017, 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.

The following potentially dilutive securities have been excluded from the computation of diluted net loss per share since their inclusion would be antidilutive:

8. COMMITMENTS AND CONTINGENCIES

Leases - On June 4, 2018, the Company entered into an Agreement of Lease. The Company will lease 3,983 square feet commencing on the date on which the tenant improvements being conducted have been substantially completed and for a term of 64 months from the commencement date. The Company also has an option to extend the term of the lease for one additional 60-month period. The landlord has agreed to provide the Company a contribution of up to $179,235 to the total cost of the tenant improvements. The anticipated completion date is expected during fourth quarter 2018 upon the Company taking possession and control of the physical use of the space.

Under the terms of the lease, the Company must pay a security deposit of $75,000 and the aggregate rent due over the term of the lease is approximately $828,000, which will be reduced to approximately $783,000 after certain rent abatements. The Company will also be required to pay its proportionate share of certain operating expenses and real estate taxes applicable to the leased premises.

The Company has agreed to extend its lease payments for its Madison, Wisconsin facility from September 14, 2018 to January 14, 2019. This additional time is needed for the Company to remove certain alterations, additions, and improvements required upon termination of the lease. Since this facility is no longer used by the Company, as of September 30, 2018 the company has recorded a liability of approximately $267,000 needed to meet its remaining obligations under the lease.

Supply of CLR 131 - On August 7, 2018, the Company was informed by Centre for Probe Development and Commercialization (“CPDC”), the Company’s sole supplier of CLR 131, that CPDC is subject to an Import Alert 66-40 (the “Import Alert”) by the United States Food and Drug Administration (“FDA”). While the basis for the Import Alert was not related to CLR 131, or CPDC’s production facility associated with CLR 131, CPDC informed the Company on August 8, 2018 that CPDC would not be able to supply CLR 131 to the Company until the Import Alert is lifted or alternative agreements are reached with the FDA. On September 24, 2018 the Company announced that the FDA had initiated direct talks with the Company concerning a possible exemption for CLR 131 from the Import Alert.

On November 8, 2018, the FDA notified the Company that it has completed its initial review concerning a possible exemption for CLR 131 from the Import Alert placed on CPDC. The FDA authorized CPDC to send shipments to the investigator sites participating in the Company’s ongoing hematology focused clinical trials, including our Phase 2 clinical study for relapsed or refractory multiple myeloma and a range of other B-cell malignancies, and its Phase 1 clinical study for relapsed or refractory multiple myeloma. As a result, the Company plans to resume patient enrollment in those clinical studies.

The Company awaits authorization from the FDA for any future shipments in connection with its Phase 1 study of pediatric patients with neuroblastoma, sarcomas, lymphomas (including Hodgkin’s lymphoma) and malignant brain tumors. As a result of the supply disruption, the Company is experiencing delays in patient enrollment for this clinical trial. At this time, the Company is not able to assess the extent of the delays or what impact the supply disruption will have on the Company, but the inability of CPDC to supply CLR 131 for this trial on a prolonged basis would result in further delayed patient enrollment. The Company intends to continue to work with CPDC and the FDA to resolve this issue as soon as practical.

Legal - The Company is involved in legal matters and disputes in the ordinary course of business. We do not anticipate that the outcome of such matters and disputes will materially affect the Company’s financial statements.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

We are a clinical stage biopharmaceutical company focused on the discovery, development and commercialization of drugs for the treatment of cancer. Our core objective is to leverage our proprietary phospholipid drug conjugate^TM (“PDCs^TM”) delivery platform to develop PDCs that specifically target cancer cells to deliver improved efficacy and better safety as a result of fewer off-target effects. The PDC platform possesses the potential for the discovery and development of the next generation of cancer-targeting treatments, and we plan to develop PDCs independently and through research and development collaborations.

Supply of CLR 131

On August 7, 2018, we were informed by Centre for Probe Development and Commercialization (“CPDC”), our sole supplier of CLR 131, that CPDC is subject to an Import Alert 66-40 (the “Import Alert”) by the United States Food and Drug Administration (“FDA”). While the basis for the Import Alert was not related to CLR 131, or CPDC’s production facility associated with CLR 131, CPDC informed us on August 8, 2018 that CPDC would not be able to supply CLR 131 to us until the Import Alert is lifted or alternative agreements are reached with the FDA. On September 24, 2018 we announced that the FDA had initiated direct talks with us concerning a possible exemption for CLR 131 from the Import Alert.

On November 8, 2018, the FDA notified us that it has completed its initial review concerning a possible exemption for CLR 131 from the Import Alert placed on CPDC. The FDA authorized CPDC to send shipments to the investigator sites participating in our ongoing hematology focused clinical trials, including our Phase 2 clinical study for relapsed or refractory multiple myeloma and a range of other B-cell malignancies, and our Phase 1 clinical study for relapsed or refractory multiple myeloma. As a result, we plan to resume patient enrollment in those clinical studies.

We await authorization from the FDA for any future shipments in connection with our Phase 1 study of pediatric patients with neuroblastoma, sarcomas, lymphomas (including Hodgkin’s lymphoma) and malignant brain tumors. As a result of the supply disruption, we are experiencing delays in patient enrollment for this clinical trial. At this time, we are not able to assess the extent of the delays or what impact the supply disruption will have on us, but the inability of CPDC to supply CLR 131 for this trial on a prolonged basis would result in further delayed patient enrollment. We intend to continue to work with CPDC and the FDA to resolve this issue as soon as practical.

CLR 131 and PDC Platform

Our lead PDC candidate, CLR 131, provides targeted delivery of the cytotoxic (cell-killing) radioisotope iodine 131. CLR 131 is in a Phase 2 study in relapsed or refractory (“R/R”) multiple myeloma (“R/RMM”) and a range of other B-cell malignancies, and a Phase 1 clinical study for R/RMM. We plan to initiate a Phase 1 study for pediatric solid tumors and lymphomas and are planning a second Phase 1 study of CLR 131 in combination with external beam radiation for head and neck cancer (“HNC”) at the University of Wisconsin Madison. Our pipeline also includes a PDC chemotherapeutic program in drug discovery, CLR 1900. CLR 1900 is being targeted for solid tumors with a payload that inhibits mitosis (cell division), which is a validated pathway for cell apoptosis.

We have leveraged our PDC platform to establish five active collaborations featuring five unique payloads and mechanisms of action. Through research and development collaborations, our strategy is to generate near-term capital, supplement internal resources, gain access to novel molecules or payloads, accelerate product candidate development and broaden our proprietary and partnered product pipelines.

Our PDC platform provides selective delivery of a diverse range of oncologic payloads to cancerous cells, whether a hematologic cancer or solid tumor, the primary tumor, or a metastatic tumor and cancer stem cells. Our PDC platform takes advantage of a metabolic pathway utilized by all currently identified tumor cell types in all currently identified stages of the tumor “cycle.” This allows the PDC molecules to gain access to the intracellular compartment of the tumor cells and for the PDCs to continue to accumulate over time, which enhances drug efficacy. The PDC platform’s mechanism of entry does not rely upon specific cell surface epitopes or antigens as are required by other targeted delivery platforms. Specific cell surface epitopes are limited in number on the cell surface, undergo internalization and cycling upon binding, and are not present on all tumor cells of a particular cancer type. This means a subpopulation of tumor cells will always remain. In addition to the benefits provided by the mechanism of entry, we believe PDCs offer the potential advantage of having the ability to be conjugated to molecules in numerous ways, thereby increasing the types of molecules selectively delivered via the PDC.

The PDC platform features include the capacity to link with almost any molecule and provide a significant increase in targeted oncologic payload delivery and the ability to target all tumor cells. As a result, we believe that we can generate PDCs to treat a broad range of cancers with the potential to improve the therapeutic index of oncologic drug payloads, enhance or maintain efficacy while reducing adverse events by minimizing drug delivery to healthy cells, and increasing delivery to cancerous cells and cancer stem cells.

We employ a drug discovery and development approach that allows us to efficiently design, research and advance drug candidates. We believe our iterative process allows us to systematically produce multiple generations of incrementally improved targeted drug candidates.

Clinical Pipeline

CLR 131 is a small-molecule, cancer-targeting radiotherapeutic PDC designed to deliver cytotoxic radiation directly and selectively to cancer cells and cancer stem cells. CLR 131 is our lead therapeutic PDC product candidate and is currently being evaluated in both Phase 2 and Phase 1 clinical studies. The Investigational New Drug (“IND”) application was accepted by the FDA in March 2014. The Phase 2 study is evaluating CLR 131 as a potential therapy for R/RMM and was initiated in November of 2017. The primary goal of the study is to assess the compound’s efficacy in a broad range of hematologic cancers. The Phase 1 study is designed to assess the compound’s safety and tolerability in patients with R/RMM and was initiated in April 2015. This clinical study is a standard three-by-three dose escalation safety study. Multiple myeloma is an incurable cancer of the plasma cells and is the second most common form of hematologic cancers. This cancer type was selected for clinical, regulatory and commercial rationales, including multiple myeloma’s highly radiosensitive nature and continued unmet medical need in the relapse/refractory setting, and has been determined to be a rare disease by the FDA based upon the current definition within the Orphan Drug Act. Secondary objectives include the evaluation of therapeutic activity by assessing surrogate efficacy markers, which include M protein, free light chain (“FLC”), progression free survival (“PFS”) and overall survival (“OS”).

In December 2014, the FDA granted orphan drug designation for CLR 131 for the treatment of multiple myeloma. In 2018, the FDA granted orphan drug and rare pediatric disease designations for CLR 131 for the treatment of neuroblastoma, rhabdomyosarcoma, Ewing’s sarcoma and osteosarcoma. The FDA previously accepted our IND application for a Phase 1 open-label, dose-escalating study to evaluate the safety and tolerability of a single intravenous administration of CLR 131 in up to 30 children and adolescents with cancers including neuroblastoma, sarcomas, lymphomas (including Hodgkin’s lymphoma) and malignant brain tumors. We plan to initiate this Phase 1 study.

Phase 2 Study in Patients with R/R select B-Cell Malignancies

In July 2016, we were awarded a $2,000,000 National Cancer Institute (NCI) Fast-Track Small Business Innovation Research grant to further advance the clinical development of CLR 131. The funds are supporting the Phase 2 study initiated in March 2017 to define the clinical benefits of CLR 131 in R/RMM and other niche hematologic malignancies with unmet clinical need. These niche hematologic malignancies include Chronic Lymphocytic Leukemia, Small Lymphocytic Lymphoma, Marginal Zone Lymphoma, Lymphoplasmacytic Lymphoma and Diffuse Large B-Cell Lymphoma (“DLBCL”). The study is being conducted in approximately 10 top U.S. cancer centers in patients with orphan-designated relapse or refractory hematologic cancers. The study’s primary endpoint is clinical benefit response, with additional endpoints of PFS, median OS and other markers of efficacy following a single 25.0 mCi/m² dose of CLR 131, with the option for a second 25.0 mCi/m² dose approximately 75-180 days later. Based on the performance results from Cohort 5 of our Phase 1 study in patients with R/RMM, reviewed below, we intend to modify the dosing regimen of this trial to a fractionated dose of 15.625 mCi/m² administered on day 1 and day 8.

In July 2018, we announced that after a single 25mCi/m² IV administration of CLR 131, patients with relapsed/refractory aggressive DLBCL were assessed for response. These interim data show a 33% overall response rate (ORR) and a 50% clinical benefit response (CBR). In addition, the observed responses to date show overall tumor reduction ranged from 60% to greater than 90%. As a result of these favorable outcomes, we have expanded this cohort to include up to 30 additional patients. We also announced that a patient in the lymphoplasmacytic lymphoma (LPL) arm with advanced Waldenstrom macroglobulinema showed a 94% reduction in tumor burden and complete resolution in four of five targeted masses after two doses of CLR 131 separated by 123 days.

Phase 1 Study in Patients with R/R Multiple Myeloma

CLR 131 in combination with dexamethasone is currently under investigation in a Phase 1 trial in adult patients with R/RMM following treatment with both a proteasome inhibitor and an immunomodulatory agent. All patients have been heavily pretreated with an average of 5 prior lines of therapy. To date, four single dose cohorts have been examined: 12.5 mCi/m², 18.75 mCi/m², 25 mCi/m², and 31.25 mCi/m², all in combination with 40 mg dexamethasone weekly. An independent Data Monitoring Committee has deemed all four single dose levels safe and tolerable. Of the five patients in the first cohort, four achieved stable disease and one patient progressed at Day 15 after administration and was taken off the study. Of the five patients that have been admitted to the second cohort, four achieved stable disease and one patient progressed at Day 41 after administration and was taken off the study. Four patients were enrolled to the third cohort and all achieved stable disease. In September 2017, we announced results for Cohort 4 results, showing that a single 30-minute infusion of 31.25mCi/m² of CLR 131 was safe and well tolerated by the three patients in the cohort. Additionally, all three patients experienced clinical benefit with one patient achieving a partial response (“PR”). We are monitoring response rates via surrogate markers of efficacy including M protein and FLC. The International Myeloma Working Group defines a PR as a greater than or equal to 50% decrease in FLC levels (for patients in whom M protein is unmeasurable) or 50% decrease in M protein. The patient experiencing a PR had an 82% reduction in FLC. This patient did not produce M protein, received seven prior lines of treatment including radiation, stem cell transplantation and multiple triple combination treatments including one with daratumumab that was not tolerated. One patient experiencing stable disease attained a 44% reduction in M protein. We have recently converted the Phase 1a clinical data (single CLR 131 dose) to pooled data for presentation of the total performance of the results to date. This is beneficial as it is a compilation of all the data and results in an N of 15, which gives the data more weight and a sense of maturity compared to reporting on individual cohorts with an N of 3-4 in each. As of October 2, 2018, the preliminary pooled OS data from the first four cohorts was 19.4 months.

Based on the safety observed to date as well as various efficacy signals, including reductions in M protein and FLC and a pooled median OS that has not yet been reached, the study protocol was modified for cohort 5 to introduce a fractionated dose of 15.625 mCi/m² administered on day 1 and day 8 to further determine the optimal dose-range for CLR 131. Results from Cohort 5 indicate enhanced tolerability and safety in comparison to Cohort 4 despite an 18% increase in total average dose from 55.29 mCi to 65.15 mCi of CLR 131. Patients in Cohort 5 required less supportive care such as transfusions of platelets or packed red blood cells than seen in previous cohorts. Furthermore, a review of surrogate efficacy markers demonstrated that patients in Cohort 5 monitored by M-protein showed a nearly 50% further reduction in M-Protein than seen in Cohort 4. Based on the results and an independent Data Monitoring Committee recommendation, the company plans to initiate a sixth cohort using a fractionated two dose regimen of 18.75 mCi/m² administered one week apart.

Phase 1 Study in R/R Pediatric Patients with Select Solid Tumors, Lymphomas and Malignant Brain Tumors.

On December 14, 2017, we filed an IND application with the Division of Oncology at the FDA for a proposed Phase 1 study of CLR 131 in children and adolescents with select rare and orphan designated cancers. The Phase 1 clinical trial of CLR 131 is an open-label, sequential-group, dose-escalation study to evaluate the safety and tolerability of a single intravenous administration of CLR 131 in up to 30 children and adolescents with cancers including neuroblastoma, sarcomas, lymphomas (including Hodgkin's lymphoma) and malignant brain tumors. Secondary objectives of the study are to identify the recommended Phase 2 dose of CLR 131 and to determine preliminary antitumor activity (treatment response) of CLR 131 in children and adolescents. Over the period of time from March 2018 to September 2018, the FDA granted orphan drug designation and rare pediatric disease designations for CLR 131 for the treatment of neuroblastoma, rhabdomyosarcoma, Ewing’s sarcoma and pediatric osteosarcoma. We plan to initiate this Phase 1 study at 3-5 pediatric cancer centers across the US.

Phase 1 Study in R/R Head and Neck Cancer

In August 2016, the University of Wisconsin Carbone Cancer Center (“UWCCC”) was awarded a five-year Specialized Programs of Research Excellence (SPORE) grant from the National Cancer Institute and the National Institute of Dental and Craniofacial Research to improve treatments and outcomes for head and neck cancer, HNC, patients. HNC is the sixth most common cancer across the world with approximately 56,000 new patients diagnosed every year in the U.S. As a key component of this grant, the UWCCC researchers will test CLR 131 in various animal HNC models as well as initiating the first human clinical trial combining CLR 131 and external beam radiation in patients with recurrent HNC. The UWCCC is currently anticipated to initiate this clinical trial in the second half of 2019. 

Preclinical Pipeline

We believe our PDC platform has potential to provide targeted delivery of a diverse range of oncologic payloads, as exemplified by the product candidates listed above, that may result in improvements upon current standard of care for the treatment of a broad range of human cancers.

Results of Operations

Research and development expense.  Research and development expense consists of costs incurred in identifying, developing and testing, and manufacturing product candidates, which primarily include salaries and related expenses for personnel, costs of our research and manufacturing facility, cost of manufacturing materials and contract manufacturing fees paid to contract research organizations, fees paid to medical institutions for clinical trials, and costs to secure intellectual property. The Company analyzes its research and development expenses based on four categories as follows: clinical project costs, pre-clinical project costs, manufacturing and related costs, and general research and development costs that are not allocated to the functional project costs, including personnel costs, facility costs, related overhead costs and patent costs.

General and administrative expense.  General and administrative expense consists primarily of salaries and other related costs for personnel in executive, finance and administrative functions.  Other costs include insurance, costs for public company activities, investor relations, directors’ fees and professional fees for legal and accounting services.

Three Months Ended September 30, 2018 and 2017

Research and Development. Research and development expense for the three months ended September 30, 2018 was approximately $1,996,000 compared to approximately $2,333,000 for the three months ended September 30, 2017.

The following table is a comparison summary of research and development costs for the three months ended September 30, 2018 and September 30, 2017:

The overall decrease in research and development expense of $337,000, or 14%, was primarily a result of a decrease in clinical project costs because of increased NCI contract reimbursements. Manufacturing and related costs decreased as a result of the Import Alert to CPDC by the FDA creating a supply interruption of CLR 131 during the months of August and September 2018. Pre-clinical studies increased because of additional expenditures for outsourced services. The increase in general research and development costs was primarily a result of the recording of a charge of approximately $267,000 in connection with the decommissioning of our manufacturing facility.

General and Administrative. General and administrative expense for the three months ended September 30, 2018 was approximately $1,092,000, compared to approximately $1,151,000 in the three months ended September 30, 2017. The $59,000 or 5% decrease resulted from a decrease in legal fees of $207,000 offset by an increase of $74,000 in personnel related costs and an increase of $81,000 in purchased services

Nine Months Ended September 30, 2018 and 2017

Research and Development. Research and development expense for the nine months ended September 30, 2018 was approximately $5,799,000 compared to approximately $6,366,000 for the nine months ended September 30, 2017.

The following table is a comparison summary of research and development costs for the nine months ended September 30, 2018 and September 30, 2017:

The overall decrease in research and development expense of approximately $567,000, or 9%, was due primarily to a decrease in general research and development which consists primarily of research and development personnel and related costs. Pre-clinical project costs increased due to additional expenditures for outsourced services and clinical project costs decreased as a result of increased NCI contract reimbursements which are recorded as an offset against expense.

General and Administrative. General and administrative expense for the nine months ended September 30, 2018 was approximately $3,647,000, compared to approximately $3,147,000 in the nine months ended September 30, 2017. The increase of approximately $500,000, or 16%, was due to an increase of approximately $311,000 in purchased services, primarily consulting, accounting and investor relations and an increase of approximately $138,000 in personnel related costs. In connection with the decision to outsource our manufacturing, we incurred approximately $81,000 of one-time personnel related costs in the nine months ended September 30, 2018.

Our combined research and development and general and administrative headcount decreased from 15 at December 31, 2017 to 7 at September 30, 2018.

Liquidity and Capital Resources

As of September 30, 2018, we had cash and cash equivalents of approximately $16,373,000 compared to $10,006,000 as of December 31, 2017. This increase was due to the approximately $15,000,000 of net proceeds received in connection with the July 2018 public offering. Cash used in operating activities was approximately $8,699,000 during the nine months ended September 30, 2018. Net cash used in operating activities during the nine months ended September 30, 2017 was approximately $8,194,000.

Our cash requirements have historically been for our research and development activities, finance and administrative costs, capital expenditures and overall working capital. We have experienced negative operating cash flows since inception and have funded our operations primarily from sales of common stock and other securities. As of September 30, 2018, we had an accumulated deficit of approximately $93,761,000.

We believe our cash on hand is adequate to fund operations into first quarter of 2020. However, our future results of operations involve significant risks and uncertainties.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures. Based on our management’s evaluation (with the participation of our principal executive officer and principal financial officer), as of September 30, 2018, our management has concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) were effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms.

Changes in internal control over financial reporting. There have not been any significant changes in the Company’s internal control over financial reporting.

The Chief Executive Officer and the Audit Committee perform significant roles in ensuring the accuracy and completeness of our financial reporting and the effectiveness of our disclosure controls and procedures. We have not identified any changes that occurred during the Company’s fiscal quarter ended September 30, 2018 that materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Important Considerations. Any system of controls, however well designed and operated, can provide only reasonable, and not absolute assurance that the objectives of the system are met. In addition, the design of any control system is based in part on certain assumptions about the likelihood of future events. The effectiveness of our disclosure controls and procedures is subject to various inherent limitations, including cost limitations, judgments used in decision making, assumptions about the likelihood of future events, the soundness of our systems, the possibility of human error, and the risk of fraud. Because of these and other inherent limitations of control systems, there can be no assurance that any system of disclosure controls and procedures will be successful in achieving its stated goals, including but not limited to preventing all errors or fraud or in making all material information known in a timely manner to the appropriate levels of management, under all potential future conditions, regardless of how remote.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

None.

Item 1A. Risk Factors

Factors that could materially adversely affect our business and our equity securities are described in the Risk Factors previously disclosed in the prospectus filed with the SEC on July 27, 2018 pursuant to Rule 424(b) of the Securities Act (the “Prospectus”). This information should be considered carefully, together with other information in this report and other reports and materials we file with the SEC. In addition, the following risk factor included substantive changes from those disclosed in the Prospectus:

We rely on a collaborative outsourced business model, and disruptions with these third-party collaborators, including potential disruptions at our sole source supplier of CLR 131, Centre for Probe Development and Commercialization (“CPDC”), may impede our ability to gain FDA approval and delay or impair commercialization of any products.

We are in the preclinical and clinical trial phases of product development and commercialization. We have closed manufacturing operations located at our corporate headquarters, and are implementing a collaboration outsourcing model to more efficiently manage costs. We rely, and will increasingly rely, on contracts with third parties to use their facilities to conduct our research, development and manufacturing.

We have engaged CPDC, which has been a validated Current Good Manufacturing Practices (“cGMPs”) manufacturing organization specializing in radiopharmaceuticals, as our exclusive source to supply drug product for our ongoing research and clinical trials, including our Phase 1 and Phase 2 studies of CLR 131. On August 7, 2018, we were notified by CPDC, our sole supplier of CLR 131, that it is subject to an Import Alert 66-40 (the “Import Alert”) by the FDA. While the basis for the Import Alert was not related to CLR 131, or CPDC’s production facility associated with CLR 131, CPDC informed us on August 8, 2018 that CPDC would not be able to supply CLR 131 to us until the Import Alert is lifted or alternative agreements are reached with the FDA. On September 24, 2018, we announced that the FDA had initiated direct talks with us concerning a possible exemption for CLR 131 from the Import Alert. On November 8, 2018, the FDA notified us that it has completed its initial review concerning a possible exemption for CLR 131 from the Import Alert placed on CPDC. The FDA authorized CPDC to send shipments to the investigator sites participating in our ongoing hematology focused clinical trials, including our Phase 2 clinical study for relapsed or refractory multiple myeloma and a range of other B-cell malignancies, and our Phase 1 clinical study for relapsed or refractory multiple myeloma. As a result, we plan to resume patient enrollment in those clinical studies.

We continue to await authorization from the FDA for any future shipments in connection with our Phase 1 study of pediatric patients with neuroblastoma, sarcomas, lymphomas (including Hodgkin’s lymphoma) and malignant brain tumors. As a result of the supply disruption, we are experiencing delays in enrollment in this clinical trial. At this time, we are not able to assess the extent of the delays or what impact the supply disruption will have on us, but the inability of CPDC to supply CLR 131 for this trial on a prolonged basis would result in further delayed patient enrollment. We intend to continue to work with CPDC and the FDA to resolve this issue as soon as practical.

In addition, we rely exclusively on contract research organizations to conduct research and development. Any inability of these organizations to fulfill the requirements of their agreements with us may delay or impair our ability to gain FDA approval and commercialization of our drug delivery technology and products.

Our reliance on third-party collaborators may expose us to the risk of not being able to directly oversee the activities of these parties. Furthermore, these collaborators, whether foreign or domestic, may experience regulatory compliance difficulties, mechanical shutdowns, employee strikes, or other unforeseeable acts that may delay fulfillment of their agreements with us. Failure of any of these collaborators to provide the required services in a timely manner or on commercially reasonable terms could materially delay the development and approval of our products, increase our expenses, and materially harm our business, prospects, financial condition and results of operations.

We believe that we have a good working relationship with our third-party collaborators. However, should the situation change, we may be required to relocate these activities on short notice, and we do not currently have access to alternate facilities to which we could relocate our research, development and/or manufacturing activities. The cost and time to establish or locate an alternate research, development and/or manufacturing facility to develop our technology would be substantial and would delay obtaining FDA approval and commercializing our products.

Furthermore, if our products are approved for commercial sale, we will need to work with our existing third-party collaborators to ensure sufficient capacity, or engage additional parties with the capacity, to commercially manufacture our products in accordance with FDA and other regulatory requirements. There can be no assurance that we would be able to successfully establish any such capacity or identify suitable manufacturing partners on acceptable terms.
