(Unaudited)

1.     Organization and business

Incyte Corporation (“Incyte,” “we,” “us,” or “our”) is a drug discovery and development company focused on developing proprietary small molecule drugs to treat serious unmet medical needs. We have a pipeline with programs focused primarily in the areas of oncology, inflammation, and diabetes.

2.     Summary of significant accounting policies

Basis of presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X.  The condensed consolidated balance sheet as of March 31, 2009 and the condensed consolidated statements of operations, comprehensive loss, and cash flows for the three months ended March 31, 2009 and 2008 are unaudited, but include all adjustments, consisting only of normal recurring adjustments, which we consider necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented.  The condensed consolidated balance sheet at December 31, 2008 has been derived from audited financial statements.

Although we believe that the disclosures in these financial statements are adequate to make the information presented not misleading, certain information and footnote information normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission.

Results for any interim period are not necessarily indicative of results for any future interim period or for the entire year. The accompanying financial statements should be read in conjunction with the financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2008.

Recent Accounting Pronouncements

Effective January 1, 2009, we adopted Staff Position No. Accounting Principles Board 14-1, Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion (Including Partial Cash Settlement) (“FSP No. APB 14-1”). FSP No. APB 14-1 requires that the liability and equity components of convertible debt instruments that may be settled in cash upon conversion (including partial cash settlement) be separately accounted for in a manner that reflects an issuer’s nonconvertible debt borrowing rate. FSP No. APB 14-1 was effective for us as of January 1, 2009. The adoption of APB 14-1 had no impact on our consolidated financial statements.

Effective January 1, 2009, we adopted Emerging Issues Task Force (“EITF”) Issue No. 07-5, Determining Whether an Instrument (or Embedded Feature) Is Indexed to an Entity’s Own Stock (“EITF 07-5”). EITF 07-5 provides guidance in assessing whether an equity-linked financial instrument (or embedded feature) is indexed to an entity’s own stock for purposes of determining whether the appropriate accounting treatment falls under the scope of Statement of Financial Accounting Standards (“SFAS”) No. 133, Accounting For Derivative Instruments and Hedging Activities and/or EITF 00-19, Accounting For Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock. EITF 07-5 is effective for financial statements issued for fiscal years beginning after December 15, 2008 and early application is not permitted. The adoption of EITF 07-5 had no impact on our consolidated financial statements.

In April 2009, the Financial Accounting Standards Board (“FASB”) issued FASB Staff Position (“FSP”) FAS 157-4, Determining Fair Value when the Volume and Level of Activity for the Asset or Liability have Significantly Decreased and Identifying Transactions that are not Orderly (“FSP 157-4”), which is effective for our interim and annual periods commencing with our June 30, 2009 consolidated financial statements and will be applied on a prospective basis. FSP 157-4 affirms that the objective of fair value when the market for an asset is not active is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. The FSP provides guidance for estimating fair value when the volume and level of market activity for an asset or liability have significantly decreased and determining whether a transaction was orderly. This FSP applies to all fair value measurements when appropriate. We are currently evaluating the impact of the adoption of this statement on our financial statements based on current market conditions.

In April 2009, the FASB issued FSP FAS 115-2, Recognition and Presentation of Other-Than-Temporary Impairments (“FSP 115-2”), which is effective for us for the quarterly period beginning April 1, 2009. FSP 115-2 amends existing guidance for determining whether an other than temporary impairment of debt securities has occurred. Among other changes, the FASB replaced the existing

7

Table of Contents

requirement that an entity’s management assert it has the positive intent and ability to hold an impaired security until recovery with a requirement that management assert (a) it does not have the intent to sell the security, and (b) it is not more likely than not it will be required to sell the security before recovery of its amortized cost basis. FAS 115-2 may require a cumulative effect adjustment upon adoption for the non-credit related component of previously recognized other-than-temporary impairments. We are currently evaluating the impact of the adoption of FSP 115-2 on our financial statements.

In April 2009, the FASB issued FSP FAS 107-1 and APB 28-1, Interim Disclosures about Fair Value of Financial Instruments (“FSP 107-1”), which is effective for us for the quarterly period beginning April 1, 2009. FSP 107-1 requires an entity to provide the annual disclosures required by FASB Statement No. 107, Disclosures about Fair Value of Financial Instruments, in its interim financial statements. We are currently evaluating the impact of the adoption of FSP 107-1 on our financial statements.

3.     Marketable securities

We adopted Statement of Financial Accounting Standards No. 157, Fair Value Measurements (“SFAS 157”) effective January 1, 2008.  SFAS 157 defines fair value as the price that would be received to sell an asset or paid to transfer a liability (“the exit price”) in an orderly transaction between market participants at the measurement date.  The standard outlines a valuation framework and creates a fair value hierarchy in order to increase the consistency and comparability of fair value measurements and the related disclosures.  In determining fair value we use quoted prices and observable inputs. Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of us. The fair value hierarchy is broken down into three levels based on the source of inputs as follows:

Level 1 — Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 — Valuations based on observable inputs and quoted prices in active markets for similar assets and liabilities.

Level 3 — Valuations based on inputs that are unobservable and models that are significant to the overall fair value measurement.

We have determined that our fair value requirements are in accordance with the requirements of SFAS 157, therefore, the implementation of SFAS 157 did not have any impact on our consolidated financial condition or results of operations.  Our marketable securities consist of investments in corporate debt securities, mortgage and asset-backed securities, U.S. Treasury notes, and other U.S. government agency securities that are classified as available-for-sale. We classify marketable securities available to fund current operations as current assets on the condensed consolidated balance sheet. Marketable securities are classified as long-term assets on the consolidated balance sheets if (i) they have been in an unrealized loss position for longer than six months and (ii) we have the ability to hold them until the carrying value is recovered and such holding period may be longer than one year.

The following fair value hierarchy table presents information about each major category of our financial assets and liabilities measured at fair value on a recurring basis as of March 31, 2009 (in thousands):

4.     Revenues

For the three months ended March 31, 2009, one customer contributed 48% of revenues.  For the three months ended March 31, 2008, one customer contributed 45% of revenues.

Three customers comprised 82% of the accounts receivable balance at March 31, 2009. Three customers comprised 78% of the accounts receivable balance at December 31, 2008.

Contract revenues related to the upfront consideration received, research services provided to Pfizer Inc. (“Pfizer”) under our collaborative research and license agreement with Pfizer, and the difference between the cash received and the present value of convertible subordinated notes issued to Pfizer (the “Pfizer Notes”), of approximately $0.0 million and $0.6 million, respectively, were recognized for the three months ended March 31, 2009 and 2008.

5.     Stock compensation

Under the provisions of Statement of Financial Accounting Standards No. 123 (revised 2004) (“SFAS 123R”), we recorded $3.4 million and $3.3 million of stock compensation expense on our unaudited condensed consolidated statement of operations for the three months ended March 31, 2009 and 2008, respectively. We utilized the Black-Scholes valuation model for estimating the fair value of the stock compensation granted, with the following weighted-average assumptions:

The risk-free interest rate is derived from the U.S. Federal Reserve rate in effect at the time of grant. The expected life calculation is based on the observed and expected time to the exercise of options by our employees based on historical exercise patterns for similar type options. Expected volatility is based on the historical volatility of our common stock over the period commensurate with the expected life of the options. A dividend yield of zero is assumed based on the fact that we have never paid cash dividends and have no present intention to pay cash dividends.

Based on our historical experience, we have assumed an annualized forfeiture rate of 5% for our options. Under the true-up provisions of SFAS 123R, we will record additional expense if the actual forfeiture rate is lower than we estimated, and will record a recovery of prior expense if the actual forfeiture is higher than we estimated.

The amortization of stock compensation under SFAS 123R for the period after its adoption was calculated in accordance with FASB Interpretation (“FIN”) No. 28. Total compensation cost of options granted but not yet vested, as of March 31, 2009, was $9.1 million, which is expected to be recognized over the weighted average period of 2.99 years.

The following table summarizes activity under all stock option plans:

6.     Net loss per share

For all periods presented, both basic and diluted net loss per common share are computed by dividing the net loss by the number of weighted average common shares outstanding during the period. Stock options and potential common shares issuable upon conversion of our 3 1/2% convertible senior notes due 2011 (the “3 1/2% Senior Notes”), 3 1/2% convertible subordinated notes due 2011 (the “3 1/2% Subordinated Notes”) and the Pfizer Notes were excluded from the computation of diluted net loss per share, as their share effect was anti-dilutive for all periods presented. The potential common shares that were excluded from the diluted net loss per share computation are as follows:

Overview

Incyte is a drug discovery and development company focused on developing proprietary small molecule drugs to treat serious unmet medical needs. We have a broad pipeline with programs focused primarily in the areas of oncology, inflammation, and diabetes.

Our wholly-owned pipeline includes the following compounds:

In early 2009, we announced that due to the challenging economic environment, we intend to focus our efforts on clinical programs that we believe have a greater likelihood of creating near-term value.  We do not intend to initiate clinical trials in 2009 for our c-MET inhibitor or our selective inhibitor of the enzyme IDO unless we are successful in securing additional funding.  We also intend to move INCB28050 forward as our lead oral anti-inflammatory compound and have discontinued the development of INCB18424 in rheumatoid arthritis.  Programs that will not receive funding in 2009 include: our JAK inhibitor programs for hormone refractory prostate cancer and multiple myeloma; our HM74a agonist for type 2 diabetes; our CCR2 receptor antagonist for multiple sclerosis; and our CCR5 receptor antagonist for HIV.

Table of Contents

We anticipate incurring additional losses for several years as we expand our drug discovery and development programs. We also expect that losses will fluctuate from quarter to quarter and that such fluctuations may be substantial. Conducting clinical trials for our drug candidates in development is a lengthy, time-consuming and expensive process. We do not expect to generate product sales from our drug discovery and development efforts for several years, if at all. If we are unable to successfully develop and market pharmaceutical products over the next several years, our business, financial condition and results of operations would be adversely impacted.

Critical Accounting Policies and Significant Estimates

The preparation of financial statements requires us to make estimates, assumptions and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. On an on-going basis, we evaluate our estimates. We base our estimates on historical experience and various other assumptions that we believe to be reasonable under the circumstances, the results of which form our basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from those estimates under different assumptions or conditions.

We believe the following critical accounting policies affect the more significant judgments and estimates used in the preparation of our consolidated financial statements:

·      Investments;

·      Revenue recognition;

·      Research and development costs;

·      Valuation of long-lived assets;

·      Restructuring charges; and

·      Stock compensation.

Investments. We account for investments in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 115, Accounting for Certain Investments in Debt and Equity Securities. We carry our investments at their respective fair values. We periodically evaluate the fair values of our investments to determine whether any declines in the fair value of investments represent an other-than-temporary impairment. This evaluation consists of a review of several factors, including the length of time and extent that a security has been in an unrealized loss position, the existence of an event that would impair the issuer’s future repayment potential, the near term prospects for recovery of the market value of a security and our intent and ability to hold the security until the market values recover, which may be maturity. If management determines that such an impairment exists, we would recognize an impairment charge. Because we may determine that market or business conditions may lead us to sell a short-term investment or marketable security prior to maturity, we classify our short-term investments and marketable securities as “available-for-sale.” Investments in securities that are classified as available-for-sale and have readily determinable fair values are measured at fair market value in the balance sheets, and unrealized holding gains and losses for these investments are reported as a separate component of stockholders’ equity until realized. We classify those marketable securities that may be used in operations within one year as short-term investments. Those marketable securities in which we have both the ability to hold until maturity and have a maturity date beyond one year from our most recent consolidated balance sheet date are classified as long-term marketable securities.

Revenue Recognition. Revenues are recognized when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price is fixed and determinable and collectibility is reasonably assured. We have entered into various types of agreements for access to our information databases and use of our intellectual property. Revenues are deferred for fees received before earned or until no further obligations exist. We exercise judgment in determining that collectibility is reasonably assured or that services have been delivered in accordance with the arrangement. We assess whether the fee is fixed or determinable based on the payment terms associated with the transaction and whether the sales price is subject to refund or adjustment. We assess collectibility based primarily on the customer’s payment history and on the creditworthiness of the customer.

Revenues from ongoing database agreements are recognized evenly over the access period. Revenues from licenses to our intellectual property are recognized when earned under the terms of the related agreements. Royalty revenues are recognized upon the sale of products or services to third parties by the licensee or other agreed upon terms. We estimate royalty revenues based on previous period royalties received and information provided by the third party licensee. We exercise judgment in determining whether the information provided by licensees is sufficiently reliable for us to base our royalty revenue recognition thereon.

15

Table of Contents

Under agreements involving multiple products, services and/or rights to use assets, the multiple elements are divided into separate units of accounting when certain criteria are met, including whether the delivered items have stand alone value to the customer and whether there is objective and reliable evidence of the fair value of the undelivered items. When separate units of accounting exist, consideration is allocated among the separate elements based on their respective fair values. The determination of fair value of each element is based on objective evidence from historical sales of the individual elements by us to other customers. If such evidence of fair value for each undelivered element of the arrangement does not exist, all revenue from the arrangement is deferred until such time that evidence of fair value for each undelivered element does exist or until all elements of the arrangement are delivered. When elements are specifically tied to a separate earnings process, revenue is recognized when the specific performance obligation tied to the element is completed. When revenues for an element are not specifically tied to a separate earnings process, they are recognized ratably over the term of the agreement.

Research and Development Costs. In accordance with SFAS No. 2, Accounting for Research and Development Costs, it is our policy to expense research and development costs as incurred. We often contract with clinical research organizations (“CROs”) to facilitate, coordinate and perform agreed upon research and development of a new drug. To ensure that research and development costs are expensed as incurred, we record monthly accruals for clinical trials and preclinical testing costs based on the work performed under the contract.

These CRO contracts typically call for the payment of fees for services at the initiation of the contract and/or upon the achievement of certain clinical trial milestones. In the event that we prepay CRO fees, we record the prepayment as a prepaid asset and amortize the asset into research and development expense over the period of time the contracted research and development services are performed in accordance with Emerging Issues Task Force (“EITF”) Issue No. 07-3, Accounting for Nonrefundable Advance Payments for Goods or Services to Be Used in Future Research and Development Activities. Most professional fees, including project and clinical management, data management, monitoring, and medical writing fees are incurred throughout the contract period. These professional fees are expensed based on their percentage of completion at a particular date.

Our CRO contracts generally include pass through fees. Pass through fees include, but are not limited to, regulatory expenses, investigator fees, travel costs, and other miscellaneous costs, including shipping and printing fees. We expense the costs of pass through fees under our CRO contracts as they are incurred, based on the best information available to us at the time. The estimates of the pass through fees incurred are based on the amount of work completed for the clinical trial and are monitored through correspondence with the CROs, internal reviews and a review of contractual terms. The factors utilized to derive the estimates include the number of patients enrolled, duration of the clinical trial, estimated patient attrition, screening rate and length of the dosing regimen. CRO fees incurred to set up the clinical trial are expensed during the setup period.

Valuation of Long-Lived Assets. We assess the impairment of long-lived assets, which includes property and equipment as well as intangible and other assets, whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors we consider important that could indicate the need for an impairment review include the following:

·      Significant changes in the strategy of our overall business;

·      Significant underperformance relative to expected historical or projected future operating results;

·      Significant changes in the manner of use of the acquired assets;

·      Significant negative industry or economic trends;

·      Significant decline in our stock price for a sustained period; and

·      Our market capitalization relative to net book value.

When we determine that the carrying value of long-lived assets may not be recoverable based upon the existence of one or more of the above indicators of impairment, in accordance with SFAS No. 144, Accounting for the Impairment or Disposal of Long Lived Assets, we perform an undiscounted cash flow analysis to determine if impairment exists. If impairment exists, we measure the impairment based on the difference between the asset’s carrying amount and its fair value.

Restructuring Charges. Costs associated with restructuring activities initiated after December 31, 2002, are accounted for in accordance with SFAS No. 146, Accounting for Costs Associated with Exit or Disposal Activities (“SFAS 146”). Costs associated with restructuring activities initiated prior to December 31, 2002 have been recorded in accordance with EITF Issue No. 94-3, Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring) and Staff Accounting Bulletin No. 100, Restructuring and Impairment Charges. Restructuring costs resulting from the acquisition of Maxia Pharmaceuticals, Inc. (“Maxia”) have been recorded in accordance with EITF Issue No. 95-3, Recognition of Liabilities in Connection with a Purchase Business Combination. The restructuring charges are comprised primarily of costs to exit facilities, reduce our workforce, write-off fixed assets, and pay for outside services incurred in the restructuring. The workforce reduction charge is determined based on the estimated severance and fringe benefit charge for identified employees. In calculating the

16

Table of Contents

cost to exit the facilities, we estimate for each location the amount to be paid in lease termination payments, the future lease and operating costs to be paid until the lease is terminated, the amount, if any, of sublease receipts and real estate broker fees. This requires us to estimate the timing and costs of each lease to be terminated, the amount of operating costs, and the timing and rate at which we might be able to sublease the site. To form our estimates for these costs, we perform an assessment of the affected facilities and consider the current market conditions for each site. We also estimate our credit adjusted risk free interest rate in order to discount our projected lease payments in accordance with SFAS 146. Estimates are also used in our calculation of the estimated realizable value on equipment that is being held for sale. These estimates are formed based on recent history of sales of similar equipment and market conditions. Our assumptions on either the lease termination payments, operating costs until terminated, the offsetting sublease receipts and estimated realizable value of fixed assets held for sale may turn out to be incorrect and our actual cost may be materially different from our estimates. Our estimates of future liabilities may change, requiring us to record additional restructuring charges or reduce the amount of liabilities recorded.

At the end of each reporting period, we evaluate the remaining accrued balances to ensure their adequacy, that no excess accruals are retained and the utilization of the provisions are for their intended purposes in accordance with developed exit plans. We periodically evaluate current available information and adjust our restructuring reserve as necessary. We also make adjustments related to accrued professional fees to adjust estimated amounts to actual.

Stock Compensation.  Effective January 1, 2006, we adopted SFAS No. 123 (revised 2004) (“SFAS 123R”), Share-Based Payment, which revised SFAS No. 123, Accounting for Stock-Based Compensation. SFAS 123R requires all share-based payment transactions with employees, including grants of employee stock options, to be recognized as compensation expense over the requisite service period based on their relative fair values. SFAS 123R requires significant judgment and the use of estimates, particularly surrounding Black-Scholes assumptions such as stock price volatility and expected option lives, as well as expected option forfeiture rates, to value equity-based compensation. SFAS 123R requires the recognition of the fair value of stock compensation in the statement of operations. Under the provisions of SFAS 123R, we recorded $3.4 million and $3.3 million of stock compensation expense for the three months ended March 31, 2009 and 2008, respectively.

Results of Operations

We recorded a net loss of $40.0 million and basic and diluted net loss per share of $0.41 for the three months ended March 31, 2009 as compared to a net loss of $40.2 million and basic and diluted net loss per share of $0.47 in the corresponding period in 2008.

Revenues.

Our contract revenues for the three months ended March 31, 2009 decreased to $0.0 million from $0.6 million for the three months ended March 31, 2008, as, by June 30, 2008, we had fully recognized contract revenues associated with the Pfizer $40.0 million upfront fee, the debt discount and beneficial conversion feature related to the Pfizer Notes and the reimbursement of certain expenses by Pfizer for research and development expenses pursuant to the collaborative research and license agreement.

Our license and royalty revenues for the three months ended March 31, 2009 and 2008 were the same, $0.7 million.  License and royalty revenues were derived from the licensing of our gene- and genomic-related intellectual property.   We expect that revenues generated from information products, including licensing of gene- and genomic-related intellectual property, will decline as we focus on our drug discovery and development programs.

Operating Expenses.

Research and development expenses.

17

Table of Contents

We currently track research and development costs by natural expense line and not costs by project.  For salary and benefit related costs, the increase from the three months ended March 31, 2008 to the three months ended March 31, 2009 was primarily the result of increased headcount to sustain our development pipeline.  Stock compensation was essentially flat for the three months ended March 31, 2009 as compared to the three months ended March 31, 2008.  Stock compensation expense may fluctuate from period to period based on the number of options granted, stock price volatility and expected option lives, as well as expected option forfeiture rates which are used to value equity-based compensation.  For clinical research and outside services, the decrease from the three months ended March 31, 2008 to the three months ended March 31, 2009 is due to prioritization of our pipeline to focus on products we believe have a greater likelihood of creating near-term value.  The decrease in occupancy and all other costs for the three months ended March 31, 2009 as compared to the three months ended March 31, 2008 was due to a decrease in depreciation and patent expense.

Research and development expenses may fluctuate from period to period depending upon the stage of certain projects and the level of pre-clinical and clinical trial-related activities.  Many factors can affect the cost and timing of our clinical trials, including requests by regulatory agencies for more information, inconclusive results requiring additional clinical trials, slow patient enrollment, adverse side effects among patients, insufficient supplies for our clinical trials and real or perceived lack of effectiveness or safety of our investigational drugs in our clinical trials.  In addition, the development of all of our products will be subject to extensive governmental regulation. These factors make it difficult for us to predict the timing and costs of the further development and approval of our products.

Selling, general and administrative expenses.

For salary and benefit related costs, the increase from the three months ended March 31, 2008 to the three months ended March 31, 2009 was primarily the result of increased headcount.  The increased headcount was due to initial sales and marketing preparations for the potential commercialization of INCB18424 for myeloproliferative disorders.  Stock compensation expense and other contract service and outside costs were essentially flat for the three months ended March 31, 2009 as compared to the corresponding period in 2008.

Other expenses.     Total other expenses for the three months ended March 31, 2009 were $0.5 million compared to $0.1 million for the corresponding period in 2008, and represent charges recorded in connection with previously announced restructuring programs.

Interest and Other Income, Net.     Interest and other income, net, for the three months ended March 31, 2009 was $0.5 million compared to $2.1 million for the corresponding period in 2008.   The decrease is due primarily to a lower average cash balance and yield for the three months ended March 31, 2009 as compared to the corresponding period in 2008.

Interest Expense.    Interest expense for the three months ended March 31, 2009 was $6.3 million compared to $6.2 million for the corresponding period in 2008.

Liquidity and Capital Resources

Due to our significant research and development expenditures, we have not been profitable and have generated operating losses since we were incorporated in 1991 through 1996 and in 1999 through March 31, 2009.  As such, we have funded our research and development operations through sales of equity securities, the issuance of convertible notes, cash received from customers, and collaborative arrangements. As of March 31, 2009, approximately $17.9 million of marketable securities were classified as long-term assets on the consolidated balance sheet as they had been in an unrealized loss position for longer than six months and we have the intent and ability to hold them until the carrying value recovers, which may be longer than one year. At March 31, 2009, we had available cash, cash equivalents, and short-term and long-term marketable securities of $175.6 million. Our cash and marketable securities balances are held in a variety of interest- bearing instruments including money market accounts, obligations of U.S. government agencies, high-grade corporate bonds, and asset backed and mortgage backed securities. Available cash is invested in accordance with our investment policy’s primary objectives of liquidity, safety of principal and diversity of investments. Recent

distress in the financial markets has had an adverse impact on financial market activities including, among other things, extreme volatility in security prices, severely diminished liquidity and credit availability, rating downgrades of certain investments and declining valuations of others. We have assessed the implications of these factors on our current business and determined that there had not been a significant impact to our financial position, results of operations or liquidity for the period ended March 31, 2009.

Net cash used in operating activities was $42.7 million for the three months ended March 31, 2009, compared to $37.4 million for the three months ended March 31, 2008.  The $5.3 million increase was due primarily to changes in working capital.

Our investing activities, other than purchases, sales and maturities of marketable securities, have consisted predominantly of capital expenditures.  Net cash provided by investing activities was $3.1 million for the three months ended March 31, 2009, which represented primarily sales and maturities of marketable securities of $3.2 million.  In the future, net cash used by investing activities may fluctuate significantly from period to period due to the timing of capital expenditures, maturities/sales and purchases of marketable securities, and acquisitions, including possible earn-out payments to former stockholders of Maxia.

Net cash provided by financing activities was $0.0 million and $0.5 million for the three months ended March 31, 2009 and 2008, respectively.  For the three months ended March 31, 2008, we received $0.5 million from issuance of common stock under our stock plans and employee stock purchase plan.

The following summarizes our significant contractual obligations as of March 31, 2009 and the effect those obligations are expected to have on our liquidity and cash flow in future periods:

The amounts and timing of payments related to vacated facilities may vary based on negotiated timing of lease terminations.  We have entered into sublease agreements for our vacated space with scheduled payments to us of $2.7 million (less than 1 year) and $2.3 million (years 1-3); these scheduled payments are not reflected in the above table.

The table above excludes certain commitments that are contingent upon future events. The most significant of these contractual commitments that we consider to be contingent obligations are summarized below.

Commitments related to Maxia are considered contingent commitments as future events must occur to cause these commitments to be enforceable.  In February 2003, we completed our acquisition of Maxia.  Under the merger agreement, former Maxia stockholders have the right to receive certain earn out amounts of up to a potential aggregate amount of $14.0 million upon the occurrence of certain research and development milestones set forth in the merger agreement.  Twenty percent of each earn out payment, if earned, will be paid in cash and the remaining eighty percent will be paid in shares of our common stock such that an aggregate of $2.8 million in cash and $11.2 million in our common stock (based upon the then fair value) could potentially be paid pursuant to the earn out milestones.  The milestones are set to occur as Maxia products enter various stages of human clinical trials and may be earned at any time prior to the tenth anniversary of the consummation of the merger.  In any event, no more than 13,531,138 shares of our common stock may be issued to former Maxia stockholders in the aggregate pursuant to the merger agreement.  None of these milestones has been achieved as of March 31, 2009.

We have entered into and may in the future seek to license additional rights relating to technologies in connection with our drug discovery and development programs.  Under these licenses, we may be required to pay up-front fees, milestone payments, and royalties on sales of future products.

We believe that our cash, cash equivalents and marketable securities will be adequate to satisfy our capital needs for at least the next twelve months. Our cash requirements depend on numerous factors, including our expenditures in connection with potential repayments of our 31/2% convertible senior notes due 2011, 31/2% convertible subordinated notes due 2011, and the Pfizer Notes; expenditures in connection with our drug discovery and development programs; expenditures in connection with litigation or other legal proceedings; competing technological and market developments; the cost of filing, prosecuting, defending and enforcing patent

claims and other intellectual property rights; our receipt of any milestone or other payments under any collaborative agreements we may enter into, including the agreement with Pfizer; and expenditures in connection with alliances and license agreements. Changes in our research and development plans or other changes affecting our operating expenses may result in changes in the timing and amount of expenditures of our capital resources. We expect that future revenues generated from information products, including licensing of intellectual property, will continue to decline as we focus on drug discovery and development programs and, in 2009, will not represent a significant source of cash inflow for us. We intend to continue to evaluate options to repurchase or refinance our outstanding convertible notes that mature in February 2011. Repurchases might occur through cash purchases and/or exchanges for other securities in open market transactions, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved in any such transactions, individually or in the aggregate, may be material. Any issuance of equity securities in exchange for our outstanding convertible notes may be dilutive to our stockholders.

Until we can generate a sufficient amount of product revenues to finance our cash requirements, which we may never do, we expect to finance future cash needs primarily through public or private equity offerings, debt financings, borrowings or strategic collaborations. The sale of equity or additional convertible debt securities in the future may be dilutive to our stockholders, and may provide for rights, preferences or privileges senior to those of our holders of common stock. Debt financing arrangements may require us to pledge certain assets or enter into covenants that could restrict our operations or our ability to incur further indebtedness. We do not know whether additional funding will be available on acceptable terms, if at all. Recently, the credit markets and the financial services industry have been experiencing a period of unprecedented turmoil and upheaval characterized by the bankruptcy, failure, collapse or sale of various financial institutions and an unprecedented level of intervention from the United States federal government. These events have generally made equity and debt financing difficult to obtain. If we are not able to secure additional funding when needed, we may have to scale back our operations, delay or eliminate one or more of our research or development programs, or attempt to obtain funds by entering into an agreement with a collaborative partner that would result in terms that are not favorable to us or relinquishing our rights in certain of our proprietary technologies or drug candidates.

Off Balance Sheet Arrangements

We have no off-balance sheet arrangements other than those that are discussed above.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

Our investments in marketable securities, which are composed primarily of investment-grade corporate bonds, U.S. government agency debt securities, mortgage and asset-backed securities and money market funds, are subject to default, changes in credit rating and changes in market value.  These investments are also subject to interest rate risk and will decrease in value if market rate interest rates increase.  As of March 31, 2009, cash, cash equivalents and short-term and long-term marketable securities were $175.6 million.  Due to the nature of these investments, if market interest rates were to increase immediately and uniformly by 10% from levels as of March 31, 2009 the decline in fair value would not be material.

Item 4.    Controls and Procedures

Evaluation of disclosure controls and procedures.    We maintain “disclosure controls and procedures,” as such term is defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”), that are designed 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, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.  In designing and evaluating our disclosure controls and procedures, management recognized that disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met.  Our disclosure controls and procedures have been designed to meet reasonable assurance standards.  Additionally, in designing disclosure controls and procedures, our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures.  The design of any disclosure controls and procedures also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Based on their evaluation as of the end of the period covered by this Quarterly Report on Form 10-Q, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in internal control over financial reporting.    There was no change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during our last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II:    OTHER INFORMATION

Item 1A.   Risk Factors

RISKS RELATING TO OUR BUSINESS

We are at the early stage of our drug discovery and development efforts and we may be unsuccessful in our efforts.

We are in the early stage of building our drug discovery and development operations. Our ability to discover, develop and commercialize pharmaceutical products will depend on our ability to:

·                  hire and retain key scientific employees;

·                  identify high quality therapeutic targets;

·                  identify potential drug candidates;

·                  develop products internally or license drug candidates from others;

·                  identify and enroll suitable human subjects, either in the United States or abroad, for our clinical trials;

·                  complete laboratory testing and clinical trials on humans;

·                  obtain and maintain necessary intellectual property rights to our products;

·                  obtain and maintain necessary regulatory approvals for our products, both in the United States and abroad;

·                  enter into arrangements with third parties to provide services or to manufacture our products on our behalf;

·                  deploy sales and marketing resources effectively or enter into arrangements with third parties to provide these functions;

·                  lease facilities at reasonable rates to support our growth; and

·                  enter into arrangements with third parties to license and commercialize our products.

We have limited experience with the activities listed above and may not be successful in discovering, developing, or commercializing drug products.

Our efforts to discover and develop potential drug candidates may not lead to the discovery, development, commercialization or marketing of drug products.

Our drug candidates in clinical trials are in Phase I and Phase II trials. Our other drug candidates are still undergoing preclinical testing. We have also licensed to Pfizer our portfolio of CCR2 antagonist compounds. We have no control over the further clinical development of any compounds we licensed to Pfizer. Discovery and development of potential drug candidates are expensive and time-consuming, and we do not know if our efforts will lead to discovery of any drug candidates that can be successfully developed and marketed. If our efforts do not lead to the discovery of a suitable drug candidate, we may be unable to grow our clinical pipeline or we may be unable to enter into agreements with collaborators who are willing to develop our drug candidates. Of the compounds that we identify as potential drug products or that we in-license from other companies, only a few, if any, are likely to lead to successful drug development programs. For example, in 2006, we discontinued the development of DFC, which was at the time our most advanced drug candidate and was in Phase IIb clinical trials. Prior to discontinuation of the DFC program, we expended a significant amount of effort and money on that program.

The success of our drug discovery and development efforts may depend on our ability to find suitable collaborators to fully exploit our capabilities. If we are unable to establish collaborations or if these future collaborations are unsuccessful, our research and development efforts may be unsuccessful, which could adversely affect our results of operations and financial condition.

An important element of our business strategy will be to enter into collaborative or license arrangements with other parties, such as our collaboration with Pfizer, under which we license our drug candidates to those parties for development and commercialization. We expect that while we plan to conduct initial clinical trials on our drug candidates, we may need to seek collaborators for our drug candidates such as our chemokine receptor antagonists because of the expense, effort and expertise required to continue additional clinical trials and further develop those drug candidates. We may also seek collaborators for our drug candidates that target large primary care indications such as diabetes because of the expense involved in further clinical development of these indications and in establishing a sales and marketing organization to address these indications. Because collaboration arrangements are complex to

21

Table of Contents

negotiate, we may not be successful in our attempts to establish these arrangements. Also, we may not have drug compounds that are desirable to other parties, or we may be unwilling to license a drug compound because the party interested in it is a competitor. The terms of any such arrangements that we establish may not be favorable to us. Alternatively, potential collaborators may decide against entering into an agreement with us because of our financial, regulatory or intellectual property position or for scientific, commercial or other reasons. If we are not able to establish collaborative agreements, we may not be able to develop and commercialize a drug product, which would adversely affect our business and our revenues.

In order for any of these collaboration or license arrangements to be successful, we must first identify potential collaborators or licensees whose capabilities complement and integrate well with ours. We may rely on these arrangements for not only financial resources, but also for expertise or economies of scale that we expect to need in the future relating to clinical trials, manufacturing, sales and marketing, and for licenses to technology rights. However, it is likely that we will not be able to control the amount and timing of resources that our collaborators or licensees devote to our programs or potential products. If our collaborators or licensees prove difficult to work with, are less skilled than we originally expected or do not devote adequate resources to the program, the relationship will not be successful. If a business combination involving a collaborator or licensees and a third party were to occur, the effect could be to diminish, terminate or cause delays in development of a potential product.

We face significant competition for our drug discovery and development efforts, and if we do not compete effectively, our commercial opportunities will be reduced or eliminated.

The biotechnology and pharmaceutical industries are intensely competitive and subject to rapid and significant technological change. Our drug discovery and development efforts may target diseases and conditions that are already subject to existing therapies or that are being developed by our competitors, many of which have substantially greater resources, larger research and development staffs and facilities, more experience in completing preclinical testing and clinical trials, and formulation, marketing and manufacturing capabilities. As a result of these resources, our competitors may develop drug products that render our products obsolete or noncompetitive by developing more effective drugs or by developing their products more efficiently. Our ability to develop competitive products would be limited if our competitors succeeded in obtaining regulatory approvals for drug candidates more rapidly than we were able to or in obtaining patent protection or other intellectual property rights that limited our drug development efforts. Any drugs resulting from our research and development efforts, or from our joint efforts with collaborators or licensees, might not be able to compete successfully with our competitors’ existing and future products, or obtain regulatory approval in the United States or elsewhere.

We depend on our collaboration with Pfizer for the development and commercialization of CCR2 antagonist compounds.

Under our collaborative research and license agreement with Pfizer, Pfizer gained worldwide development and commercialization rights to our portfolio of CCR2 antagonist compounds. Pfizer’s rights extend to the full scope of potential indications, with the exception of multiple sclerosis and autoimmune nephritides.

Although Pfizer is required to use commercially reasonable efforts to develop and commercialize CCR2 antagonists for the indications for which they are responsible, we cannot control the amount and timing of resources Pfizer may devote to the development of CCR2 antagonists. Any failure of Pfizer to perform its obligations under our agreement could negatively impact the development of CCR2 antagonists, lead to our loss of potential revenues from product sales and milestones and delay our achievement, if any, of profitability.

Pfizer has certain rights to terminate the license agreement, including the right to terminate upon 90 days’ notice for any reason. Pfizer also has the right to terminate its rights and obligations with respect to certain indications and licensed compounds. If Pfizer terminates the license agreement or its rights with respect to certain indications, we may not be able to find a new collaborator to replace Pfizer, and our business could be adversely affected.

If conflicts arise between our collaborators, including Pfizer, licensees, or advisors and us, our collaborators, licensees, or advisors may act in their self-interest, which may adversely affect our business.

If conflicts arise between us and our collaborators or licensees, including Pfizer, or our scientific advisors, the other party may act in its self-interest and not in the interest of our stockholders. Conflicts may arise with our collaborators or licensees if they pursue alternative technologies or develop alternative products either on their own or in collaboration with others as a means for developing treatments for the diseases that we have targeted. Competing products, either developed by these future collaborators or licensees or to which these future collaborators or licensees have rights, may result in their withdrawal of support for our product candidates.

Additionally, conflicts may arise if there is a dispute about the achievement and payment of a milestone amount or the ownership of intellectual property that is developed during the course of the relationship. Similarly, the parties to a collaboration or license agreement may disagree as to which party owns newly developed products. Should an agreement be terminated as a result of a dispute and before we have realized the benefits of the collaboration or license, our reputation could be harmed and we may not obtain revenues that we anticipated receiving.

Table of Contents

We have limited expertise with and capacity to conduct preclinical testing and clinical trials, and our resulting dependence on other parties could result in delays in and additional costs for our drug development efforts.

We have only limited experience with clinical trials, formulation, manufacturing and commercialization of drug products. We also have limited internal resources and capacity to perform preclinical testing and clinical trials. As a result, we intend to continue to hire clinical research organizations, or CROs, to perform preclinical testing and clinical trials for drug candidates. If the CROs that we hire to perform our preclinical testing and clinical trials or our collaborators or licensees do not meet deadlines, do not follow proper procedures, or a conflict arises between us and our CROs, our preclinical testing and clinical trials may take longer than expected, may be delayed or may be terminated. If we were forced to find a replacement entity to perform any of our preclinical testing or clinical trials, we may not be able to find a suitable entity on favorable terms, or at all. Even if we were able to find another company to perform a preclinical test or clinical trial, the delay in the test or trial may result in significant additional expenditures. Events such as these may result in delays in our obtaining regulatory approval for our drug candidates or our ability to commercialize our products and could result in increased expenditures that would adversely affect our operating results.

In addition, for some of our drug candidates, we plan to contract with collaborators or licensees to advance those candidates through later-stage, more expensive clinical trials, rather than invest our own resources to perform these clinical trials. Depending on the terms of our agreements with these collaborators or licensees, we may not have any control over the conduct of these clinical trials, and in any event we would be subject to the risks associated with depending on collaborators or licensees to develop these drug candidates.

If we are unable to obtain regulatory approval to develop and market products in the United States and foreign jurisdictions, we will not be permitted to manufacture or commercialize products resulting from our research.

In order to manufacture and commercialize drug products in the United States, our drug candidates will have to obtain regulatory approval from the Food and Drug Administration, or the FDA. Satisfaction of regulatory requirements typically takes many years. To obtain regulatory approval, we must first show that our drug products are safe and effective for target indications through preclinical testing (animal testing) and clinical trials (human testing). Preclinical testing and clinical development are long, expensive and uncertain processes, and we do not know whether the FDA will allow us to undertake clinical trials of any potential drug products in addition to our compounds currently in clinical trials.

Completion of clinical trials may take several years and failure may occur at any stage of testing. The length of time required varies substantially according to the type, complexity, novelty and intended use of the product candidate. Interim results of a preclinical test or clinical trial do not necessarily predict final results, and acceptable results in early clinical trials may not be repeated in later clinical trials. For example, a drug candidate that is successful at the preclinical level may cause harmful or dangerous side effects when tested at the clinical level. Our rate of commencement and completion of clinical trials may be delayed by many factors, including:

·      the high degree of risk associated with drug development;

·      our inability to formulate or manufacture sufficient quantities of materials for use in clinical trials;

·      variability in the number and types of patients available for each study;

·      difficulty in maintaining contact with patients after treatment, resulting in incomplete data;

·      unforeseen safety issues or side effects;

·      poor or unanticipated effectiveness of drug candidates during the clinical trials; or

·      government or regulatory delays.

Regulatory authorities may delay or prevent the initiation of clinical trials for our drug candidates. For example, we may be unable to successfully complete discussions with the FDA regarding trial design, including agreement on appropriate dosing and specific endpoints, for the registration trials for our JAK inhibitor for myelofibrosis.

Data obtained from clinical trials are susceptible to varying interpretation, which may delay, limit or prevent regulatory approval. A number of companies in the pharmaceutical industry, including biotechnology companies, have suffered significant setbacks in advanced clinical trials, even after achieving promising results in earlier clinical trials. In addition, regulatory authorities may refuse or delay approval as a result of other factors, such as changes in regulatory policy during the period of product development and regulatory agency review. For example, the FDA has in the past required and could in the future require that we conduct additional trials of any of our product candidates, which would result in delays.

Due, in part, to the early stage of our drug candidate research and development process, we cannot predict whether regulatory approval will be obtained for any product we develop. Our drug candidates in clinical trials are in Phase I and Phase II trials. Our other drug candidates are still undergoing preclinical testing. We have also licensed to Pfizer our portfolio of CCR2 antagonist compounds. We have no control over the further clinical development of any compounds we licensed to Pfizer. Compounds developed by us, alone or with other parties, may not prove to be safe and effective in clinical trials and may not meet all of the applicable regulatory

23

Table of Contents

requirements needed to receive marketing approval. If regulatory approval of a product is granted, this approval will be limited to those disease states and conditions for which the product is demonstrated through clinical trials to be safe and effective. Failure to obtain regulatory approval would delay or prevent us from commercializing products.

Outside the United States, our ability to market a product is contingent upon receiving a marketing authorization from the appropriate regulatory authorities. This foreign regulatory approval process typically includes all of the risks associated with the FDA approval process described above and may also include additional risks. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly from country to country and may require us to perform additional testing and expend additional resources. Approval by the FDA does not ensure approval by regulatory authorities in other countries, and approval by one foreign regulatory authority does not ensure approval by regulatory authorities in other countries or by the FDA.

We may not obtain a special protocol assessment for our JAK inhibitor for myelofibrosis. A special protocol assessment does not guarantee any particular outcome from regulatory review, including any regulatory approval.

We have filed a request with the FDA for a special protocol assessment, or SPA, for the registration trials for our JAK inhibitor for myelofibrosis. The SPA process allows for FDA evaluation of a clinical trial protocol intended to form the primary basis of an efficacy claim in support of a new drug application, or NDA, and provides a product sponsor with an agreement confirming that the design and size of the trial will be appropriate to form the primary basis of an efficacy claim for an NDA if the trial is performed according to the SPA. However, an SPA must be agreed to by the FDA before a trial conducted under an SPA can be initiated, and there is no guarantee that an SPA would be agreed to on a timely basis. Accordingly, if we submit a request for an SPA, the initiation of this trial may be delayed. If we believe that the submission of a request for an SPA or the failure to reach agreement on an SPA will significantly delay the initiation of this trial, we may determine not to revise an SPA request in an attempt to reach agreement with the FDA or to proceed with the trial and not to wait for agreement on an SPA. Without the FDA’s concurrence on an SPA, we cannot be certain that the design, conduct and data analysis approach for this clinical trial will be sufficient to allow us to submit or receive approval of a JAK inhibitor for the treatment of myelofibrosis.

An SPA is not a guarantee of approval, and we cannot be certain that the design of, or data collected from, the trial will be adequate to demonstrate safety and efficacy, or otherwise be sufficient to support regulatory approval. There can be no assurance that the terms of an SPA will ultimately be binding on the FDA, and the FDA is not obligated to approve an NDA, if any, even if the clinical outcome is positive. The FDA retains significant latitude and discretion in interpreting the terms of an SPA and the data and results from a clinical trial, and can require trial design changes if issues arise essential to determining safety or efficacy. In addition, data may subsequently become available that causes the FDA to reconsider the previously agreed upon scope of review and the FDA may have subsequent safety or efficacy concerns that override an SPA, and we can give no assurance that as clinical trials proceed or as part of an NDA review process, if any, the FDA will determine that a previously approved SPA is still valid.

Additionally, an SPA may be changed only with written agreement of the FDA, and any further changes we may propose to the protocol will remain subject to the FDA’s approval. The FDA may not agree to any such an amendment and, even if they agree, they may request other amendments to the trial design that could require additional cost and time, as well as increase the degree of difficulty in reaching clinical endpoints. As a result, even with an SPA, we cannot be certain that the trial results will be found to be adequate to support an efficacy claim and product approval.

Our reliance on other parties to manufacture our drug candidates could result in a short supply of the drugs, delays in clinical trials or drug development, increased costs and withdrawal or denial of the regulatory authority’s approval.

We do not currently operate manufacturing facilities for clinical or commercial production of our drug candidates. We expect to continue to rely on third parties for the manufacture of our drug candidates and any drug products that we may develop. The FDA requires that drug products be manufactured according to its current Good Manufacturing Practices, or cGMP, regulations and a limited number of manufacturers comply with these requirements. If the other parties that we choose to manufacture our drug products are not compliant with cGMP, the FDA may not approve our application to manufacture our drug products. We may not be able to arrange for our drug candidates or any drug products that we may develop to be manufactured by one of these parties on reasonable terms, if at all. Failure to comply with cGMP in the manufacture of our products could result in the FDA withdrawing or denying regulatory approval of our drug product or other enforcement actions.
