Summary of Significant Accounting Policies [Abstract] |
Use of Estimates | Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and related disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Critical estimates include inputs used to determine clinical trial accruals and stock-based compensation expense. Cyclacel reviews its estimates on an ongoing basis. The estimates are based on historical experience and on various other assumptions that the Company believes to be reasonable under the circumstances. Actual results may differ from these estimates. Cyclacel believes the judgments and estimates required by the following accounting policies to be significant in the preparation of the Company’s consolidated financial statements.
Foreign Currency and Currency Translation | Foreign Currency and Currency Translation Transactions that are denominated in a foreign currency are remeasured into the functional currency at the current exchange rate on the date of the transaction. Any foreign currency-denominated monetary assets and liabilities are subsequently remeasured at current exchange rates, with gains or losses recognized as foreign exchange (losses) gains in the statement of operations. The assets and liabilities of the Company’s international subsidiary are translated from its functional currency into United States dollars at exchange rates prevailing at the balance sheet date. Average rates of exchange during the period are used to translate the statement of operations, while historical rates of exchange are used to translate any equity transactions. Translation adjustments arising on consolidation due to differences between average rates and balance sheet rates, as well as unrealized foreign exchange gains or losses arising from translation of intercompany loans that are of a long-term-investment nature, are recorded in other comprehensive loss.
Cash and Cash Equivalents | Cash and Cash Equivalents Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents. The Company considers all highly liquid investments with an original maturity of three months or less at the time of initial purchase to be cash equivalents. The objectives of the Company’s cash management policy are to safeguard and preserve funds, to maintain liquidity sufficient to meet Cyclacel’s cash flow requirements and to attain a market rate of return. The Company deposits its cash in financial institutions that it believes have high credit quality and has not experienced any losses on such accounts and does not believe it is exposed to any significant credit risk on cash and cash equivalents. The Company’s cash and cash equivalents balance at December 31, 2022 was $18.6 million and it maintains its cash accounts in several entities both within the United States and the United Kingdom. The cash balances for amounts held in the United States are insured by the Federal Deposit Insurance Corporation, or FDIC up to $250,000 per account. The Company has cash balances exceeding the balance insured by the FDIC that totaled approximately $17.8 million at December 31, 2022. The cash balances for amounts held in the United Kingdom are insured by the UK Government Financial Services Compensation Scheme, or FSCS up to £85,000 per account. The Company has cash balances exceeding the balance insured by the FSCS that totaled approximately $0.2 million at December 31, 2022.
Property and Equipment | Property and Equipment The components of property and equipment are stated at cost and depreciated on a straight-line basis over the estimated useful lives of the related assets, which are generally three to five years. Amortization of leasehold improvements is performed using the straight-line method over the shorter of the remaining lease term or the estimated useful life of the related assets, currently less than one year. Upon sale or retirement of assets, the costs and related accumulated depreciation and amortization are removed from the balance sheet and the resulting gain or loss on sale is reflected as a component of operating income or loss. Expenditures for maintenance and repairs are charged to operating expenses as incurred.
Impairment of Long-lived Assets | Impairment of Long-lived Assets The Company reviews property and equipment for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. The Company assesses the recoverability of the potentially affected long-lived assets by determining whether the carrying value of such assets can be recovered through undiscounted future operating cash flows. Impairment, if any, is measured as the amount by which the carrying amount of a long-lived asset or asset group exceeds its fair value.
Fair Value of Financial Instruments | Fair Value of Financial Instruments Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Assets and liabilities measured at fair value are classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable:
| ● | Level 1 — Quoted prices in active markets for identical assets or liabilities.
| ● | Level 2 — Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data.
| ● | Level 3 — Unobservable inputs that are supported by little or no market activity that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques.
The carrying values of cash and cash equivalents, other receivables, accounts payable and accrued expenses approximate their fair values due to the short-term nature of these assets and liabilities.
Segments | Segments The Company is managed and operated as one business which is focused on using cell cycle, transcriptional regulation and mitosis control biology to develop innovative, targeted medicines for cancer and other proliferative diseases. The entire business is managed by a single management team that reports to the Chief Executive Officer. The Company does not operate separate lines of business with respect to any of its products or product candidates and the Company does not prepare discrete financial information with respect to separate products or product candidates or by location. Accordingly, the Company views its business as one reportable operating segment with development operations in two geographic areas, namely the United States and the United Kingdom.
Revenue recognition | Revenue Recognition The Company recognizes revenue in accordance with Accounting Standards Codification (ASC) 606, Revenue from Contracts with Customers. The Company had no revenue in 2021 or 2022 under such contracts. Royalty income, if any, is recognized when the licensee sells the underlying product to which the royalty relates.
Other Income | Other Income Other income is primarily related to royalty income received under a historical Asset Purchase Agreement for activities which are not part of the Company’s ongoing operations and activities.
Research and Development Costs | Research and Development Costs Research and development expenses consist primarily of costs associated with the development of the Company’s product candidates, including upfront fees, milestones, compensation and other expenses for research and development personnel, supplies and development materials, costs for consultants and related contract research, facility costs and depreciation. Expenditures relating to research and development are expensed as incurred.
Clinical Trial Accounting | Clinical Trial Accounting Data management and monitoring of the Company’s clinical trials are performed with the assistance of contract research organizations, or CROs or clinical research associates, or CRAs in accordance with the Company’s standard operating procedures. Typically, CROs and CRAs bill monthly for services performed, and others bill based upon milestones achieved. The Company accrues unbilled clinical trial expenses based on estimates of the level of services performed each period. Clinical trial costs related to patient enrollment are accrued as patients are entered into and progress through the trial.
Patent Costs | Patent Costs Patent prosecution costs are charged to general and administrative expenses as incurred as recoverability of such expenditure is uncertain.
Leases | Leases The Company accounts for lease contracts in accordance with ASC 842. As of December 31, 2021 and 2022, all of the Company’s leases are classified as operating leases. The Company recognizes an asset for the right to use an underlying leased asset for the lease term and records lease liabilities based on the present value of the Company’s obligation to make lease payments under the lease. As the Company’s leases do not indicate an implicit rate, the Company uses a best estimate of its incremental borrowing rate to discount the future lease payments. The Company estimates its incremental borrowing rate based on observable information about risk-free interest rates that are the same tenure as the lease term, adjusted for various factors, including the effects of assumed collateral, the nature of how a loan would be repaid (e.g., amortizing versus bullet), and the Company’s credit risk. The Company evaluates options included in its lease agreements to extend or terminate the lease. The Company will reflect the effects of exercising those options in the lease term when it is reasonably certain that the Company will exercise that option. In assessing whether it is reasonably certain that the Company will exercise an option, the Company considers factors such as:
| ● | The lease payments due in any optional period;
| ● | Penalties for failure to exercise (or not exercise) the option;
| ● | Market factors, such as the availability of similar assets and current rental rates for such assets;
| ● | The nature of the underlying leased asset and its importance to the Company’s operations; and
| ● | The remaining useful lives of any related leasehold improvements.
Lease expense for the Company’s operating leases is recognized on a straight-line basis over the lease term and is reported as a component of general and administrative expense. Variable lease payments, if any, are recognized in the period when the obligation to make those payments is incurred. Lease incentives received prior to lease commencement are recorded as a reduction in the right-of-use asset. Fixed lease incentives received after lease commencement reduce both the lease liability and the right-of-use asset. The Company has elected an accounting policy to account for the lease and non-lease components as a single lease component.
Stock-based Compensation | Stock-based Compensation The Company measures all stock options and other stock-based awards granted to employees and directors based on the fair value on the date of the grant and recognizes compensation expense of those awards over the requisite service period, which for the Company is the period between the grant date and the date the award vests or becomes exercisable. Many awards granted by the Company vest ratably over three or four years. However, certain awards granted to members of the Company’s Board of Directors vest in their entirety on the one-year anniversary following the date of grant. Generally, the Company issues stock options and restricted stock awards to employees with only service-based vesting conditions and records the expense for these awards using the straight-line method. However, in certain years, the Company will grant share-based payment awards to employees that are dependent upon the fulfillment of certain clinical and financial conditions. In such instances where the performance condition must be met for the award to vest, the company only recognizes compensation expense when the award is probable of vesting (See Note 12 — Stock-Based Compensation). The Company classifies stock-based compensation expenses in its statement of operations in the same manner in which the award recipient’s payroll costs are classified. The Company accounts for forfeitures as they occur. The fair value of restricted stock and restricted stock units is determined based on the number of shares granted and the quoted price of the Company’s common stock on the date of grant. The determination of grant-date fair value for stock option awards is estimated using the Black-Scholes model, which includes variables such as the expected volatility of the Company’s share price, expected term of the award, interest rates, and dividend yields. The Company relies on its historical volatility as an input to the option pricing model as management believes that this rate will be representative of future volatility over the expected term of the options. The expected term assumption is estimated using past history of early exercise behavior and expectations about future behaviors. The weighted average risk-free interest rate represents the interest rate for treasury constant maturities published by the Federal Reserve Board. If the term of available treasury constant maturity instruments is not equal to the expected term of an employee option, Cyclacel interpolates a discount rate based on the two Federal Reserve securities closest to the expected term of the employee option. The expected dividend yield is zero, as the Company has never paid cash dividends on common stock and does not expect to pay any cash dividends on common stock in the foreseeable future.
Income Taxes | Income Taxes The Company accounts for income taxes using the liability method. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized. The Company accounts for uncertainty in income taxes recognized in the financial statements by applying a two-step process to determine the amount of tax benefit to be recognized. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination by the taxing authorities. If the tax position is deemed more-likely-than-not-to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. The provision for income taxes includes the effects of any resulting tax reserves for unrecognized tax benefits that are considered appropriate as well as the related net interest and penalties. Credit is taken in the accounting period for research and development tax credits, which will be claimed from H.M. Revenue & Customs, or HMRC, the United Kingdom’s taxation and customs authority, in respect of qualifying research and development costs incurred in the same accounting period.
Net Loss Per Common Share | Net Loss Per Common Share The Company calculates net loss per common share in accordance with ASC 260 “Earnings Per Share”. Basic and diluted net loss per common share was determined by dividing the net loss applicable to common stockholders by the weighted average number of common shares outstanding during the period. Beginning in the second quarter of 2022, the Company began calculating loss per share using the two-class method. The two-class method is an allocation formula that determines loss per share for each share of common stock and redeemable common stock (see note 15), a participating security, according to dividends declared and participation rights in undistributed earnings. The reconciliation showing the loss per share attributable to common and redeemable common stockholders is discussed in Note 15 of the Notes to the Consolidated Financial Statements accompanying this Annual Report on Form 10-K. In periods in which the Company reports a net loss attributable to common stockholders, diluted net loss per share attributable to common stockholders is the same as basic net loss per share attributable to common stockholders since potentially dilutive common shares are not assumed to have been issued if their effect is anti-dilutive. The Company reported a net loss attributable to common stockholders for the years ended December 31, 2021 and 2022.
Comprehensive Income (Loss) | Comprehensive Income (Loss) All components of comprehensive income (loss), including net income (loss), are reported in the financial statements in the period in which they are recognized. Comprehensive income (loss) is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources. Net income (loss) and other comprehensive income (loss), including foreign currency translation adjustments, are reported, net of any related tax effect as applicable, to arrive at comprehensive income (loss). No taxes were recorded on items of other comprehensive income (loss). There were no reclassifications out of other comprehensive income (loss) during the years ended December 31, 2021 and 2022.
Recently Issued Accounting Pronouncements | Recently Issued Accounting Pronouncements The Financial Accounting Standards Board (“FASB”) has issued Accounting Standards Update (“ASU”) 2020-04, “Reference Rate Reform (Topic 848)”. This standard provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform initiatives that would replace interbank offered rates, including the London Interbank Offered Rate (LIBOR). For example, modifications of lease contracts within the scope of ASC 842 solely for changes in reference rates would be accounted for as a continuation of the existing contracts with no reassessments of the lease classification and the discount rate. Following the issuance of ASU 2022-06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848”, the relief remains effective for all entities as of March 12, 2020 through December 31, 2024. The Company does not currently have any contracts affected by this guidance. In November 2021, the FASB issued ASU No. 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance. This ASU requires business entities to make annual disclosures about transactions with a government they account for by analogizing to a grant or contribution accounting model under ASC 958-605 or based on International Accounting Standard No. 20. ASU 2021-10 which became effective for us on January 1, 2022. The Company has evaluated the effect that this guidance has on its Consolidated Financial Statements and has determined it does not have a material impact. In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt-Modifications and Extinguishments (Subtopic 470-50), Compensation-Stock Compensation (Topic 718), and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40). The new ASU addresses issuer’s accounting for certain modifications or exchanges of freestanding equity-classified written call options. This amendment became effective for the Company on January 1, 2022. This new guidance does not have a material impact on our financial statements for any past transactions, but it could change the way that the Company accounts for subsequent amendments to its outstanding warrants, if any.
