NOTES TO CONDENSED FINANCIAL STATEMENTS MARCH 31, 2000 (UNAUDITED) NOTE 1. BASIS OF PRESENTATION The accompanying unaudited condensed financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2000, are not necessarily indicative of the results that may be expected for the year ending December 31, 2000, or for any other future operating periods. The balance sheet at December 31, 1999 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. For further information, refer to the financial statements and footnotes thereto included in the Onyx Pharmaceuticals, Inc. (the "Company" or "Onyx") Annual Report on Form 10-K for the year ended December 31, 1999. NOTE 2. NET LOSS PER SHARE Basic net loss per share and diluted net loss per share are presented in conformity with Financial Accounting Standards Board ("FASB") Statement of Financial Accounting Standards (SFAS) No. 128, "Earnings Per Share," for all periods presented. In accordance with SFAS No. 128, basic and diluted net loss per share have been computed using the weighted-average number of shares of common stock outstanding during the period. NOTE 3. COMPREHENSIVE LOSS As of January 1, 1998, the Company adopted FASB Statement No. 130 ("SFAS 130"), "Reporting Comprehensive Income." SFAS 130 establishes new rules for the reporting and display of comprehensive income and its components; however, the adoption of SFAS 130 had no impact on the Company's net loss or stockholders' equity. SFAS 130 requires unrealized gains or losses on available-for-sale securities, which prior to adoption were reported separately in stockholders' equity, to be included in other comprehensive loss. During the three-month periods ended March 31, 2000 and March 31, 1999, total comprehensive loss equaled net loss. NOTE 4. RECENTLY ISSUED ACCOUNTING STANDARDS In June 1998, the FASB issued Statement of Financial Reporting Standards No. 133, "Accounting for Derivative Instruments and Hedging Activities" ("SFAS 133"). SFAS 133 requires that all derivative instruments be recorded on the balance sheet at their fair value. Change in the fair value of derivatives are recorded each period in current earnings or other comprehensive income, depending on whether a derivative is designed as part of a hedge transaction, and, if so, the type of hedge transaction. In June 1999, the FASB issued SFAS 137, "Accounting for Derivative Instruments and Hedging Activities--Deferral of the Effective Date of FASB Statement No. 133" ("SFAS 137"), which amends SFAS 133 to be effective for all fiscal quarters or all fiscal years beginning after June 15, 2000. Management does not currently expect that adoption of SFAS 137 will have a material impact on the Company's financial position or results of operations. On March 31, 2000, the FASB issued Interpretation No. 44, "Accounting for Certain Transactions Involving Stock Compensation," which provides guidance on several implementation issues related to Accounting Principles Board Opinion No. 25. The most significant are clarification of the definition of employee for purposes of applying Opinion No. 25 and the accounting for stock options that have been repriced. Under the interpretation, the employer-employee relationship would be based on case law and Internal Revenue Service regulations. The FASB granted an exception to this definition for outside directors. Under the interpretation, 6 ONYX PHARMACEUTICALS, INC. repriced stock options effectively changed the terms of the plan, which would make it a variable plan subject to compensation expense. The impact of the interpretation on the Company's financial position and results of operations is not expected to be material. In March 2000, the Securities and Exchange Commission delayed the implementation date of Staff Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in Financial Statements," for companies with fiscal years that begin between December 16, 1999 and March 15, 2000, to the second quarter of 2000. SAB 101 provides guidance on applying generally accepted accounting principles to revenue recognition issues in financial statements. The Company will adopt SAB 101 as required in the second quarter of 2000. The impact of the bulletin on the Company's financial position and results of operations is not expected to be material. NOTE 5. SALE OF EQUITY SECURITIES On January 18, 2000, the Company issued and sold 2,000,000 shares of its common stock at a purchase price of $9.00 per share in a private placement to four institutional investors. The Company received $18,000,000 from the private placement. On February 25, 2000, the Company issued and sold 279,470 shares of its common stock at a purchase price of $17.89 per share as the first of two stock issuances in connection with the collaboration agreement with Warner-Lambert dated October 13, 1999 and effective September 1, 1999. The Company received proceeds of $5,000,000 from the exercise of its right to require Warner-Lambert to purchase additional equity in 2000. NOTE 6. FACILITY LEASE On February 24, 2000, the Company signed a Third Amendment to its facility lease. The amendment extended the lease term to April 30, 2005. Minimum rental commitments under this amendment include a construction allowance of $568,128. 7 ONYX PHARMACEUTICALS, INC. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS EXCEPT FOR THE HISTORICAL INFORMATION CONTAINED HEREIN, THIS OVERVIEW AND THE FOLLOWING DISCUSSION CONTAIN FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS AND UNCERTAINTIES. OUR ACTUAL RESULTS COULD DIFFER MATERIALLY FROM THOSE DISCUSSED HERE. FACTORS THAT COULD CAUSE OR CONTRIBUTE TO SUCH DIFFERENCES INCLUDE, BUT ARE NOT LIMITED TO, THOSE DISCUSSED IN THE ANNUAL REPORT ON FORM 10-K FOR THE YEAR ENDED DECEMBER 31, 1999. OVERVIEW We are engaged in the discovery and development of innovative therapeutics for treatment of cancer based on our proprietary virus technology platform. We believe our technology platform represents a novel approach in developing therapeutics that selectively kill cancer cells in the body, leaving healthy, non-cancerous tissues unharmed. Our lead product candidate, ONYX-015, is genetically engineered to selectively replicate in and destroy human tumors based on the loss of p53 tumor suppressor gene function in cancer cells. We have now completed Phase II clinical trials using ONYX-015 for the treatment of head and neck cancer. Based on these results, and in collaboration with Warner-Lambert, we expect to begin a pivotal Phase III clinical trial of ONYX-015 by the middle of 2000. We are also evaluating ONYX-015 in clinical trials for a number of other cancer indications. Other potential products from our technology platform include viruses that replicate in and destroy human tumors based on defects in the RB tumor suppressor gene function in cancer cells. Additionally, we are developing armed viruses that increase the cancer killing power of the virus and expand the range of human cancers sensitive to the therapy. Further, we are working with Bayer and Warner-Lambert to identify and develop small molecule therapeutic compounds for a number of cancers. Together with Bayer, we have selected an anticancer compound for clinical development. We expect Bayer to file an IND with the FDA for this compound by the middle of 2000. We have not been profitable since inception and expect to incur substantial and increasing losses for the foreseeable future, primarily due to expenses associated with the expansion of our self-funded virus research and development programs. We expect that losses will fluctuate from quarter to quarter and that such fluctuations may be substantial. As of March 31, 2000, our accumulated deficit was approximately $79.8 million. In January 2000, we sold and issued 2,000,000 shares of common stock to four institutional investors in a private placement, at a price of $9.00 per share, for aggregate proceeds of $18,000,000. In February 2000, we sold and issued 279,470 shares of common stock to Warner-Lambert in a private placement, at a price of $17.89 per share, for aggregate proceeds of $5,000,000. Our business is subject to significant risks, including the risks inherent in our research and development efforts, the results of the ONYX-015 clinical trials, uncertainties associated with obtaining and enforcing patents, the lengthy and expensive regulatory approval process and competition from other products. We do not expect to generate revenues from the sale of proposed products in the foreseeable future. We expect that all of our revenues in the foreseeable future will be generated from collaboration agreements. 8 ONYX PHARMACEUTICALS, INC. RESULTS OF OPERATIONS THREE MONTHS ENDED MARCH 31, 2000 AND 1999. REVENUE Total revenues increased 81 percent to $5,837,000 for the three months ended March 31, 2000 as compared to $3,219,000 for the three months ended March 31, 1999. Revenues for both periods were primarily attributable to amounts earned under collaboration agreements with Warner-Lambert. Total revenue also included a $500,000 license payment from Warner-Lambert for the inflammation collaboration. The increase in revenues for the three months ended March 31, 2000 as compared to the same period in 1999 is due primarily to revenue recognized from our agreement with Warner-Lambert to develop and commercialize ONYX-015 as well as two armed therapeutic viruses. We did not have this agreement during the first three months of 1999. RESEARCH AND DEVELOPMENT EXPENSES Research and development expenses increased 15 percent to $6,070,000 for the three months ended March 31, 2000 as compared to $5,291,000 for the three months ended March 31, 1999. The increase was primarily due to contract manufacturing expenses as we scale-up production to provide ONYX-015 for our upcoming Phase III clinical trials. We expect to continue to expand the scope of our self-funded virus research and development programs in future periods, which may result in substantial increases in research and development expenses. Collaborative parties may not fund these research and development expenses. GENERAL AND ADMINISTRATIVE EXPENSES General and administrative expenses increased 39 percent to $1,842,000 for the three months ended March 31, 2000 as compared to $1,321,000 for the three months ended March 31, 1999. The increase was primarily due to employee-related expenses for hiring of additional staff and a severance agreement. We anticipate that general and administrative expenses may increase modestly in future periods in order to support increases in research and development activities. NET INTEREST INCOME We had net interest income of $395,000 and $285,000 for the three months ended March 31, 2000 and 1999, respectively. The increase in interest income was principally due to increased cash and investment balances from the $18,000,000 private placement financing in January 2000 and the $5,000,000 stock issuance to Warner-Lambert in February 2000, resulting in more interest income for the current period. LIQUIDITY AND CAPITAL RESOURCES Since our inception, our cash expenditures have substantially exceeded our revenues, and we have relied primarily on the proceeds from the sale of equity securities, revenue from collaborative research and development agreements and bank loans to fund our operations. At March 31, 2000, we had cash and investments of $37,157,000 compared with $14,463,000 at December 31, 1999. The increase in cash and investments of $22,694,000 at March 31, 2000, compared with December 31, 1999, is due to the private placement financing completed on January 18, 2000, which raised $18,000,000 and the stock issuance to Warner-Lambert on February 25, 2000, which raised $5,000,000. In addition, 9 ONYX PHARMACEUTICALS, INC. $2,317,000 of cash was received from the exercise of stock options. These increases were partially offset by cash used in operations of $1,465,000 and the repayment of debt of $550,000. We expect that cash used in operations will continue at approximately the current rate as research activities and clinical development for our virus programs progress. Total capital expenditures for equipment and leasehold improvements for the three-month period ended March 31, 2000, were $366,000. We currently expect to make expenditures for capital equipment of approximately $2,500,000 for the remainder of 2000. We believe that our existing capital resources and interest thereon and anticipated revenues from existing collaborations will be sufficient to fund our current and planned operations through at least March 2001. There can be no assurance, however, that changes in our research and development plans or other changes affecting our operating expenses will not result in the expenditure of such resources before such time, and in any event, we will need to raise substantial additional capital to fund our operations in future periods. We intend to seek such additional funding through collaborations, public and private equity or debt financings, capital lease transactions or other financing sources that may be available. However, there can be no assurance that additional financing will be available on acceptable terms or at all. If additional funds are raised by issuing equity securities, substantial dilution to existing stockholders may result. If adequate funds are not available, we may be required to delay, reduce the scope of or eliminate one or more of our research or development programs or to obtain funds through collaborations with others that are on unfavorable terms or that may require us to relinquish rights to certain of our technologies, product candidates or products that we would otherwise seek to develop on our own. BUSINESS RISKS THE RESULTS OF CLINICAL TRIALS OF ONYX-015 ARE UNCERTAIN. We have completed Phase II clinical trials of ONYX-015 for the treatment of head and neck cancer, both as a single agent and in combination with chemotherapy. Based on data from the Phase II clinical trials, we expect to initiate a Phase III clinical trial for ONYX-015 for the treatment of head and neck cancer in the middle of 2000. Historically, many pharmaceutical products have failed in Phase III testing notwithstanding favorable results in Phase II clinical trials. The results of the Phase III trials of ONYX-015 may fail to achieve primary endpoints and may demonstrate previously unforeseen side effects. The results also may not extend the findings of previous clinical trials, including response rates, duration of response or safety. There can be no assurance that the FDA will accept the results of the Phase III trials, or accept other elements of the biologics license application that we may file for ONYX-015, as being sufficient for market approval. The FDA may require additional clinical trials. Additional clinical trials will be extensive, expensive and time-consuming. If ONYX-015 fails to receive regulatory approval or regulatory approval is delayed, our business, financial condition and results of operations will be seriously harmed. In addition, our clinical trials are being conducted with patients who have failed conventional treatments and who are in the most advanced stages of cancer. During the course of treatment, these patients can die or suffer adverse medical effects for reasons that may not be related to ONYX-015. These adverse effects may impact the interpretation of clinical trial results. IF WE ARE UNSUCCESSFUL IN DEVELOPING AND COMMERCIALIZING OUR PRODUCTS, OUR BUSINESS, FINANCIAL CONDITION AND RESULTS OF OPERATIONS WOULD BE SERIOUSLY HARMED. 10 ONYX PHARMACEUTICALS, INC. None of our products has received regulatory approval, and only ONYX-015 has entered clinical trials. Accordingly, all of our products will require the commitment of substantial resources, extensive research and development, preclinical or animal testing, clinical or human trials, manufacturing scale-up and regulatory approval prior to being ready for commercial sale. There can be no assurance that commercially viable products will result from our efforts and those of parties collaborating with us. If any of our products, even if developed and approved, cannot be successfully commercialized, our business, financial condition and results of operations would be seriously harmed. WE MAY FAIL TO DEMONSTRATE THAT ONYX-015 IS EFFECTIVE FOR THE TREATMENT OF OTHER TYPES OF CANCER EVEN IF ONYX-015 IS PROVEN EFFECTIVE FOR THE TREATMENT OF HEAD AND NECK CANCER. ONYX-015 is being developed initially for treatment of head and neck cancer, using direct intratumoral injection. Even if ONYX-015 is developed successfully for this type of cancer, there can be no assurance that we will be able to demonstrate that it is effective in the treatment of a broader array of cancer types. We are in the process of completing Phase I/II clinical trials for ONYX-015 for treatment of liver metastases of colorectal cancer and for the treatment of pancreatic cancer, both as a single agent and in combination with chemotherapy. Clinical trial results are inherently uncertain. In addition, there is no assurance that we will succeed in our efforts to deliver ONYX-015 to tumors through routes of administration which are more practical for certain cancer types and less costly than direct intratumoral injection. If we are not successful in developing additional routes of administration of ONYX-015, or the drug is otherwise ineffective in the treatment of additional types of cancer, the commercial potential of this product will be reduced, even if it does receive marketing approval. THE BIOLOGICAL CHARACTERISTICS OF OUR THERAPEUTIC VIRUSES AND THEIR INTERACTIONS WITH OTHER DRUGS AND THE HUMAN IMMUNE AND OTHER DEFENSE SYSTEMS ARE NOT FULLY UNDERSTOOD. The use of therapeutic replicating viruses is novel, and we are still determining the biological characteristics of these viruses. For example, in our clinical trials to date, we have achieved the best results when ONYX-015 is used in combination with standard chemotherapy drugs, but the reasons for and the nature of the interaction of the virus with these other drugs is still uncertain. In addition, the response of the human immune system to the viral infection is still being investigated, and the immune system may play a role in limiting the tumor-killing effect of our therapeutic viruses. It is also not known to what extent the filtering organs of the body may clear our therapeutic viruses from circulation and limit the tumor-killing activity of our therapeutic viruses. Further, there is some scientific uncertainty as to whether the killing activity of ONYX-015 is specific to cells with p53 mutations. Moreover, the large number of factors that contribute to the formation of each individual patient's cancer, as well as each individual's response to treatment, is largely unknown, and each tumor is unique. These factors include not only the cancer type, but also the pressures within the tumor, the presence of interspersed normal cells and fibrous tissue, and other factors. These are among the reasons why only some cancer patients respond to a particular type of cancer therapy while others do not, even among patients with the same cancer type. The novelty and scientific uncertainties regarding our therapeutic viruses and the uniqueness of human cancers from patient-to-patient increases the risk that our product candidates will not be successfully developed, or if developed will not have a therapeutic effect in a broad patient population. WE ARE DEPENDENT UPON COLLABORATIVE RELATIONSHIPS TO DEVELOP, MANUFACTURE AND COMMERCIALIZE OUR PRODUCTS AND TO OBTAIN REGULATORY APPROVAL. Our strategy for developing, manufacturing and commercializing our products and obtaining regulatory approval depends in large part upon maintaining and entering into collaboration agreements with pharmaceutical companies or other collaborative parties. We have entered into a number of collaboration agreements with 11 ONYX PHARMACEUTICALS, INC. different collaborative parties, including research, development and marketing agreements with Warner-Lambert and Bayer. If we fail to maintain these relationships or establish new collaborative relationships, we would be required to undertake these activities at our own expense, which would significantly increase our capital requirements and limit the programs we are able to pursue, and we would be subject to significant delays with the development, manufacture or sale of our products. We are subject to a number of risks associated with our dependence upon collaborative relationships, including: - the amount and timing of expenditure of resources can vary for reasons outside our control; - business combinations and changes in a collaborative party's business strategy may adversely affect such party's willingness or ability to complete its obligations under the collaboration agreement with us; - the right of the collaborative party to terminate its collaboration agreement with us on limited notice and for reasons outside our control; - loss of significant rights to our collaborative parties if we fail to meet our obligations under these agreements; - disagreements as to ownership of clinical trial results or regulatory approvals, and the refusal of the FDA to recognize us as holding the regulatory approvals necessary to commercialize our products; - the collaborative party may develop or have rights to competing products and withdraw support of our products; and - disagreements may arise with a collaborative party regarding breach of the collaboration agreement or ownership of proprietary rights. These factors and other possible disagreements with collaborative parties could lead to delays in the research, development or commercialization of our products or could require or result in litigation or arbitration, which would be time consuming and expensive. If we fail to maintain these relationships or establish new collaborative relationships, our business, financial condition and results of operations would be seriously harmed. CHIRON MAY HAVE PREFERENTIAL RIGHTS TO ESTABLISH COLLABORATIONS WITH US. We were established in April 1992 by means of a transfer from Chiron Corporation to us of the drug discovery program being conducted at Chiron by Dr. Frank McCormick, our scientific founder, and his research team. Under the agreement executed at that time, we granted Chiron preferential rights to receive product licenses in the fields of diagnostics and vaccines, and also established a mechanism for our making proposals to Chiron for future collaborations. Chiron has advised us that it believes that this mechanism requires us to offer gene therapy programs to Chiron before licensing any such program to a third party. We and Chiron have different interpretations of this agreement as it relates to the scope of Chiron's rights. Chiron delivered a letter to us, under which Chiron waived any rights it has under the agreement with respect to collaborative arrangements that we may enter into with others until the end of July 2000, based on our selectively-replicating virus technology. During the period of time covered by this letter, we executed our agreement with Warner-Lambert for the development of ONYX-015 and two armed virus products. If Chiron does not grant us further waivers and asserts 12 ONYX PHARMACEUTICALS, INC. rights under the April 1992 agreement, or if disputes arise, our ability to enter into future collaborations for other product candidates would be complicated and might be delayed or interfered with. If we are unable to establish new collaborative relationships, or if our ability to enter into future collaborative arrangements are complicated, delayed or interfered with, our business, financial condition and results of operations would be seriously harmed. WARNER-LAMBERT HAS AGREED TO BE ACQUIRED BY PFIZER, INC. We have entered into multiple research and development and marketing collaboration agreements with Warner-Lambert, including a collaboration agreement related to ONYX-015. As part of our collaboration with Warner-Lambert related to ONYX-015, Warner-Lambert has agreed to manufacture ONYX-015 for commercial use. In February 2000, Warner-Lambert agreed to be acquired by Pfizer, Inc. We cannot assure you that Pfizer will be interested in continuing these collaborative relationships with us, because these collaborations address smaller markets than Pfizer generally seeks to address. We also cannot assure you that Pfizer is interested in the development of a virus technology platform or the products we seek to develop. If the acquisition of Warner-Lambert by Pfizer is consummated, then Pfizer could modify, disrupt or terminate our collaboration agreements with Warner-Lambert currently in effect, subject to the terms of such agreements. Pursuant to our agreement with Warner-Lambert relating to ONYX-015, Warner-Lambert has the right to terminate this agreement for any reason with 90 days notice, in which case they would be required to return all rights to ONYX-015 to us royalty-free. We cannot assure you that Pfizer will not modify, disrupt or terminate one or more of our collaboration agreements with Warner-Lambert pursuant to the terms of these agreements. If Pfizer terminates our agreement relating to ONYX-015, a significant portion of the $40 million Warner-Lambert is obligated to fund for the development of ONYX-015, including the cost of clinical trials, would be lost. In addition, because we do not have any sales and marketing capability, we are relying on Warner-Lambert's sales and marketing expertise to commercialize ONYX-015. Further, if Pfizer terminates our agreement relating to ONYX-015 and does not agree to continue to manufacture ONYX-015 for commercial use, we would have to establish an alternate-manufacturing source for ONYX-015, which would cause a delay in the commercial sale of ONYX-015. Such a delay, or the modification, disruption or termination of any of our current collaboration agreements with Warner-Lambert, especially our collaboration related to ONYX-015, would seriously harm our business, financial condition and results of operations. WE DO NOT HAVE CLINICAL OR COMMERCIAL SCALE MANUFACTURING EXPERTISE OR CAPABILITIES AND ARE DEPENDENT ON THIRD PARTIES TO FULFILL OUR MANUFACTURING NEEDS. We lack the resources and capabilities to manufacture our products on our own for clinical trials or in commercial quantities, and we have no experience in such manufacturing. It would require substantial funds to establish these capabilities. We have generally granted our collaborative parties the exclusive right to manufacture products resulting from our collaborations, and we expect to grant similar manufacturing rights in future collaborations. Consequently, we are dependent on third parties, including collaborative parties and contract manufacturers, to manufacture our products and product candidates. These parties may encounter difficulties in production scale-up, including problems involving production yields, quality control and quality assurance and shortage of qualified personnel. These third parties may not perform as agreed or may not continue to manufacture our products for the time required by us to successfully market our products. If these third parties fail to deliver the required quantities of our products or product candidates for clinical or commercial use on a timely basis and at commercially reasonable prices, and we fail to find a replacement manufacturer or obtain resources to develop our own manufacturing capabilities, our business will be seriously harmed. 13 ONYX PHARMACEUTICALS, INC. WE CURRENTLY RELY ON A SOLE SOURCE OR LIMITED NUMBER OF SOURCES FOR THE MANUFACTURING OF ONYX-015. We currently rely on a sole source contract manufacturer for the supply of ONYX-015 for Phase III clinical trials. This contract manufacturer has not produced materials for Phase III clinical trials for us or any other parties. In addition, there are a limited number of parties who could manufacture ONYX-015 for commercial use. If either our contract manufacturer or Warner-Lambert is unable to deliver the required quantities of ONYX-015 or either of them terminates our relationship, we may not be able to find a replacement manufacturer within a reasonable amount of time or at commercially reasonable rates. If we fail to find a replacement manufacturer or develop our own manufacturing capabilities, our business, financial condition and results of operations will be seriously harmed. WE NEED TO SCALE-UP THE MANUFACTURING PROCESS OF ONYX-015 FOR COMMERCIAL USE. To obtain regulatory approval for ONYX-015, our contract manufacturer will need to be able to produce commercial quantities of ONYX-015. To do so, we need to modify the manufacturing process to produce large quantities of ONYX-015 and obtain access to a larger manufacturing facility. This could require a significant amount of time and experimentation to meet our quality standards for ONYX-015. This will also require a significant capital investment on our part. In addition, if we do not treat patients in our Phase III pivotal trial with product from the new process manufactured at the larger facility, the FDA will most likely require a bridging study to show that the ONYX-015 produced from the new process at the larger facility is comparable to ONYX-015 produced from our existing manufacturing process at our contract manufacturer's existing facility. If we encounter difficulties in modifying the manufacturing process in time to conduct a bridging study prior to FDA review of our Phase III pivotal clinical trial, commercial sales of ONYX-015 could be delayed and our business, financial condition or results of operation could be seriously harmed. MARKET ACCEPTANCE OF OUR PRODUCTS IS UNCERTAIN. Even if our product development efforts are successful and even if the requisite regulatory approvals are obtained, our products may not gain market acceptance among physicians, patients, healthcare payers and the medical community. A number of additional factors may limit the market acceptance of products including the following: - rate of adoption by healthcare practitioners; - indications for which the product is approved; - rate of the products' acceptance by the target population; - timing of market entry relative to competitive products; - availability of alternative therapies; - price of our product relative to alternative therapies; - availability of third-party reimbursement; - extent of marketing efforts by us and third-party distributors or agents retained by us; and 14 ONYX PHARMACEUTICALS, INC. - side effects or unfavorable publicity concerning our products or similar products. WE DO NOT HAVE MARKETING OR SALES EXPERIENCE OR CAPABILITIES. We intend to enter into agreements with third parties to market and sell most of our products. We may not be able to enter into marketing and sales agreements with others on acceptable terms, if at all. To the extent that we enter into marketing and sales agreements with other companies, our revenues, if any, will depend on the efforts of others. We also have the right under our collaboration agreements to co-promote our products in conjunction with our collaborative parties. If we are unable to enter into third-party agreements or if we are exercising our rights to co-promote a product, then we will be required to develop marketing and sales capabilities. We may not successfully establish marketing and sales capabilities or have sufficient resources to do so. If we do not develop marketing and sales capabilities, we may not be able to meet our co-promotion obligations under our collaboration agreements, which could result in our losing these co-promotion rights. If we do develop such capabilities, we will compete with other companies that have experienced and well-funded marketing and sales operations. Failure to establish marketing and sales capabilities or failure to enter into marketing agreements with third parties will seriously harm our business, financial condition and results of operations. ADVERSE EVENTS IN THE FIELD OF GENE THERAPY MAY NEGATIVELY AFFECT REGULATORY APPROVAL OR PUBLIC PERCEPTION OF OUR PRODUCTS. The recent death of a patient at the University of Pennsylvania undergoing gene therapy using an adenoviral vector to deliver a therapeutic gene has been widely publicized. This death and any other adverse events in the field of gene therapy that may occur in the future may result in greater governmental regulation of our product candidates and potential regulatory delays relating to the testing or approval of our product candidates. As a result of this death, the United States Senate has commenced hearings to determine whether additional legislation is required to protect volunteers and patients who participate in gene therapy clinical trials. Based on the adverse events reported by investigators using adenoviral vectors, the Recombinant DNA Advisory Committee, or RAC, which acts as an advisory body to the National Institutes of Health, or NIH, has extensively discussed the use of adenoviral vectors in gene therapy clinical trials. Any increased scrutiny or new government regulation could delay or increase the costs of our product development efforts or clinical trials. In this regard, the patient in the University of Pennsylvania trial was receiving therapy by delivery through the hepatic artery of the liver. This route of administration is the same as the one we are using in our current Phase I/II clinical trial of ONYX-015 for liver metastases of colorectal cancer. Concern about this route of adenovirus administration could be a source of delay in further clinical trials or regulatory approvals for this type of cancer treatment. Our commercial success will depend in part on public acceptance of the use of gene therapies for the prevention or treatment of human diseases. Public attitudes may be influenced by claims that gene therapy is unsafe, and gene therapy may not gain acceptance of the public or the media. Negative public reaction to gene therapy could result in greater governmental regulation and stricter clinical trial oversight and commercial product labeling requirements of gene therapies and could cause a decrease in the demand for products we may develop. WE HAVE A HISTORY OF LOSSES AND OUR FUTURE PROFITABILITY IS UNCERTAIN. To date, we have engaged primarily in research and development. Our research and development and general and administrative expenses have resulted in substantial losses from operations. As of March 31, 2000, we had an accumulated deficit of approximately $79.8 million. We expect to incur significant and increasing operating losses over the next several years as our research and development efforts and preclinical testing and clinical trial 15 ONYX PHARMACEUTICALS, INC. activities expand. We expect that the amount of operating losses will fluctuate significantly from quarter to quarter as a result of increases or decreases in our research and development efforts, the establishment or termination of collaborations, the timing and amount of collaboration payments under the terms of our collaborative agreements, or the initiation, success or failure of clinical trials. We do not expect to generate revenues from the sale of products for the foreseeable future. We expect that substantially all of our revenues for the foreseeable future will result from payments under our collaborative agreements. Our ability to achieve profitability depends upon our success in completing development of our potential products, obtaining required regulatory approvals and manufacturing and marketing our products. WE WILL NEED SUBSTANTIAL ADDITIONAL FUNDS. We will require substantial additional funds to conduct the costly and time-consuming research, preclinical testing and clinical trials necessary to develop our technology and proposed products, and to establish or maintain relationships with collaborative parties to bring our products to market. Our future capital requirements will depend upon a number of factors, including continued scientific progress in the research and development of our technology programs, the size and complexity of these programs, our ability to establish and maintain collaboration agreements, progress with preclinical testing and clinical trials, the time and costs involved in obtaining regulatory approvals, the cost involved in preparing, filing, prosecuting, maintaining and enforcing patent claims, competing technological and market developments and product commercialization activities. If we are unable to obtain additional funds, we may be forced to delay or terminate clinical trials, curtail operations or obtain funds through collaborative and licensing arrangements that may require us to relinquish commercial rights or potential markets or grant licenses that are not favorable to us. FAILURE TO ATTRACT AND RETAIN KEY EMPLOYEES AND CONSULTANTS WILL SERIOUSLY HARM OUR BUSINESS, FINANCIAL CONDITION AND RESULTS OF OPERATIONS. Our success depends on our continued ability to attract, retain and motivate highly qualified management and scientific personnel. Because of the scientific nature of our business, we are highly dependent on principal members of our scientific and management staff. To pursue our product development plans, we will need to hire additional qualified scientific personnel to perform research and development, as well as personnel with expertise in clinical testing, government regulation and manufacturing. These requirements are also expected to require additional management personnel and the development of additional expertise by existing management personnel. We face competition for qualified individuals from numerous pharmaceutical and biotechnology companies, universities, and other research institutions. The failure to maintain our management and scientific staff and to attract additional key personnel could seriously harm our business, financial condition and results of operations. WE FACE INTENSE COMPETITION AND RAPID TECHNOLOGICAL CHANGE. We are engaged in a rapidly changing and highly competitive field. Other products and therapies that currently exist or are being developed will compete with the products we are seeking to develop and market. Many other companies are actively seeking to develop products that have disease targets similar to those we are pursuing. Some of these competitive products are in clinical trials. In particular, among other trials, Schering-Plough Corporation is conducting a Phase II clinical trial of its p53 gene therapy product in liver metastases of colorectal cancer. Aventis, Inc./Introgen Therapeutics, Inc. are also initiating a Phase III clinical trial in head and neck cancer with their p53 gene therapy products. If approved, the products of these and other competitors now in clinical trials will compete directly with ONYX-015. Other companies are developing small molecule drugs that may compete with product candidates identified in our small molecule drug programs. 16 ONYX PHARMACEUTICALS, INC. Many of our competitors, either alone or together with collaborative parties, have substantially greater financial resources and larger research and development staffs than we do. In addition, many of these competitors, either alone or together with their collaborative parties, have significantly greater experience than we do in: - developing products; - undertaking preclinical testing and human clinical trials; - obtaining FDA and other regulatory approvals of products; and - manufacturing and marketing products. Accordingly, our competitors may succeed in obtaining patent protection, receiving FDA approval or commercializing products before we do. If we commence commercial product sales, we will be competing against companies with greater marketing and manufacturing capabilities, areas in which we have limited or no experience. We also face, and will continue to face, competition from academic institutions, government agencies and research institutions. There are numerous competitors working on products to treat each of the diseases for which we are seeking to develop therapeutic products. In addition, any product candidate that we successfully develop may compete with existing therapies that have long histories of safe and effective use. Competition may also arise from: - other drug development technologies and methods of preventing or reducing the incidence of disease; - new small molecule drugs; or - other classes of therapeutic agents. Developments by competitors may render our product candidates or technologies obsolete or noncompetitive. We face and will continue to face intense competition from other companies for collaborations with pharmaceutical and biotechnology companies for establishing relationships with academic and research institutions, and for licenses to proprietary technology. These competitors, either alone or with collaborative parties, may succeed with technologies or products that are more effective than ours. WE ARE SUBJECT TO EXTENSIVE GOVERNMENT REGULATION, AND WE MAY NOT BE ABLE TO OBTAIN REGULATORY APPROVALS. Our product candidates under development are subject to extensive and rigorous domestic regulation. The FDA regulates, among other things, the development, testing, manufacture, safety, efficacy, record keeping, labeling, storage, approval, advertising, promotion, sale and distribution of biopharmaceutical products. If we market our products abroad, they also are subject to extensive regulation by foreign governments. None of our products has been approved for sale in the United States or any foreign market. Because our products involve the application of new technologies and will be based on new therapeutic approaches, our products are subject to substantial additional review by various governmental regulatory authorities, and as a result, regulatory approvals may be obtained more slowly than for products using more conventional technologies. 17 ONYX PHARMACEUTICALS, INC. The regulatory review and approval process takes many years, requires the expenditure of substantial resources, involves post-marketing surveillance, and may involve ongoing requirements for post-marketing studies. Additional or more rigorous governmental regulations may be promulgated that could delay regulatory approval of our or a collaborative party's product candidates. Delays in obtaining regulatory approvals may: - adversely affect the successful commercialization of any products that we or collaborative parties develop; - impose costly procedures on us or our collaborative parties; - diminish any competitive advantages that we or collaborative parties may attain; and - adversely affect our receipt of revenues or royalties. We expect to rely on the parties with which we collaborate to file investigational new drug applications and generally direct the regulatory approval process for many of our product candidates. Such collaborative parties may not be able to conduct clinical testing or obtain necessary approvals from the FDA or other regulatory authorities for any product candidates. If we fail to obtain required governmental approvals, we or our collaborative parties will experience delays in or be precluded from marketing products developed through our research. In addition, the commercial use of our products will be limited. If we have disagreements as to ownership of clinical trial results or regulatory approvals, and the FDA refuses to recognize us as holding the regulatory approvals necessary to commercialize our products, we may experience delays in or be precluded from marketing products developed through our research. Delays and limitations may materially adversely affect our business, financial condition and results of operations. Any required approvals, once obtained, may be withdrawn. Further, if we fail to comply with applicable FDA and other domestic or foreign regulatory requirements at any stage during the regulatory process, we, our contract manufacturers or our collaborative parties may be subject to sanctions, including: - delays; - warning letters; - fines; - product recalls or seizures; - injunctions; - refusal of the FDA or its foreign counterparts to review pending market approval applications or supplements to approval applications; - total or partial suspension of production; - civil penalties; - withdrawals of previously approved marketing applications, and 18 ONYX PHARMACEUTICALS, INC. - criminal prosecutions. We and our contract manufacturers also are required to comply with the applicable FDA current good manufacturing practice regulations, which include requirements relating to quality control and quality assurance as well as the corresponding maintenance of records and documentation. Further, manufacturing facilities must be approved by the FDA before they can be used to manufacture our products, and are subject to additional FDA inspection. We or our contract manufacturers may not be able to comply with the applicable good manufacturing practice requirements and other FDA regulatory requirements. After a product has received approval from the FDA, we cannot guarantee the FDA will permit us to market the product for applications beyond those for which approval was granted, or that the FDA will grant us approval for separate product applications which represent extensions of our basic technology, or that existing approvals will not be withdrawn or modified in a significant manner. Further, it is possible that the FDA will promulgate additional regulations restricting the sale of our products. Labeling and promotional activities are subject to scrutiny by the FDA and state regulatory agencies and, in some circumstances, by the Federal Trade Commission. FDA enforcement policy prohibits the marketing of approved products for unapproved, or off-label, uses. These regulations, and the FDA's interpretation of them, may impair our ability to effectively market products for which we gain approval. Failure to comply with these requirements can result in regulatory enforcement action by the FDA. In addition, problems or failures with the products of others, including our competitors, could have an adverse effect on our ability to obtain or maintain regulatory approval for any of our product candidates or products. CLINICAL TRIALS ARE EXPENSIVE, AND THEIR OUTCOMES ARE UNCERTAIN. Conducting clinical trials is a lengthy, time-consuming and expensive process. Before obtaining regulatory approvals for the commercial sale of any of our product candidates, we or collaborative parties must demonstrate through preclinical testing and clinical trials that the product is safe and effective for use in humans. We will incur substantial expense for, and devote a significant amount of time to, preclinical and clinical testing and clinical trials. Historically, the results from preclinical testing and early clinical trials have not been predictive of results obtained in later clinical trials involving large-scale testing of patients in comparison to control groups. Clinical trials may require the enrollment of large numbers of patients and suitable patients may be difficult to identify and recruit. A number of companies in the pharmaceutical industry have suffered significant setbacks in every stage of clinical trials, even in advanced clinical trials after promising results in earlier trials. The length of time of a clinical trial generally varies substantially according to the type, complexity, novelty and intended use of the product candidate. Our commencement and rate of completion of clinical trials may be delayed by many factors, including: - inability to acquire sufficient quantities of materials for use in clinical trials; - competition for and inability to enroll a sufficient number of suitable patients for testing and inability to adequately follow patients after treatment; - variations in interpretation of data obtained from trials; 19 ONYX PHARMACEUTICALS, INC. - failure to meet or comply with efficacy, safety or quality applicable standards; or - government or regulatory delays. Our product candidates may fail to demonstrate safety and efficacy in clinical trials. This failure may delay development of our other product candidates, and hinder our ability to conduct related preclinical testing and clinical trials. Failure to obtain regulatory approval for our product candidates may also create difficulties in obtaining additional financing. These failures will seriously harm our business, financial condition and results of operations. WE MAY NOT BE ABLE TO PROTECT OUR INTELLECTUAL PROPERTY OR OPERATE OUR BUSINESS WITHOUT INFRINGING UPON THE INTELLECTUAL PROPERTY RIGHTS OF OTHERS. Our technology will be protected from unauthorized use by others only to the extent that it is covered by valid and enforceable patents or effectively maintained as trade secrets. As a result, our success depends in part on our ability to: - obtain patents; - license technology rights from others; - protect trade secrets; - operate without infringing upon the proprietary rights of others; and - prevent others from infringing on our proprietary rights. We cannot be certain that our patents or patents that we license from others will be enforceable and afford protection against competitors. The patent positions of biotechnology and pharmaceutical companies are highly uncertain and involve complex legal and factual questions. Therefore, we cannot predict the breadth of claims that will be allowed under our patent applications or their enforceability. Our patents or patent applications, issued or pending, respectively, may be challenged, invalidated or circumvented. Our patent rights may not provide us with proprietary protection or competitive advantages against competitors with similar technologies. Others may independently develop technologies similar to ours or independently duplicate our technologies. Due to the extensive time required for development, testing and regulatory review of our potential products, our patents may expire or remain in existence for only a short period following commercialization. This would reduce or eliminate any advantage the patents may give us. We cannot be certain that we were the first to make the inventions covered by each of our issued or pending patent applications or that we were the first to file patent applications for such inventions. We may need to license the right to use third-party patents and intellectual property to continue development and marketing of our products. We may not be able to acquire such required licenses on acceptable terms, if at all. If we do not obtain such licenses, we may need to design around other parties' patents, or we may not be able to proceed with the development, manufacture or sale of our products. We may face litigation to defend against claims of 20 ONYX PHARMACEUTICALS, INC. infringement, assert claims of infringement, enforce our patents, protect our trade secrets or know-how, or determine the scope and validity of others' proprietary rights. Patent litigation is costly. In addition, we may require interference proceedings declared by the United States Patent and Trademark Office to determine the priority of inventions relating to our patent applications. Litigation or interference proceedings could have a material adverse effect on our business, financial condition and results of operations, and we could be unsuccessful in our efforts to enforce our intellectual property rights. Specifically, we are aware of patent applications filed in the United States and abroad that, if they were to issue, would cover ONYX-015 and other selectively-replicating viruses, and we are aware of patent applications that claim enzymes for converting prodrugs to their active forms for treating disease, including cancers, and methods of delivering the enzymes using a virus. If any of these patents are issued and we are unable to successfully challenge any claims asserting that our product candidates or products infringe the patent, or design around the patent or negotiate a reasonable license under the patent, our business, financial condition and results of operations would be seriously harmed. WE FACE PRODUCT LIABILITY RISKS AND MAY NOT BE ABLE TO OBTAIN ADEQUATE INSURANCE. The use of any of our product candidates in clinical trials and the sale of any approved products, may expose us to liability claims resulting from such use or sale of our products. These claims might be made directly by consumers, healthcare providers or by pharmaceutical companies or others selling such products. We may experience financial losses in the future due to product liability claims. We have obtained limited product liability insurance coverage for our clinical trials. We intend to expand our insurance coverage to include the sale of commercial products if marketing approval is obtained for product candidates in development. However, insurance coverage is becoming increasingly expensive. We may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses. If a successful product liability claim or series of claims is brought against us for uninsured liabilities or in excess of insured liabilities, our business, financial condition and results of operations would be seriously harmed. OUR OPERATIONS INVOLVE HAZARDOUS MATERIALS. Our research and process development activities involve the controlled use of hazardous materials. We cannot eliminate the risk of accidental contamination or injury from these materials. In the event of an accident or environmental discharge, we may be held liable for any resulting damages, which may exceed our financial resources and may seriously harm our business. In addition, if we develop a manufacturing capacity, we may incur substantial costs to comply with environmental regulations and would be subject to the risk of accidental contamination or injury from the use of hazardous materials in our manufacturing process. ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Our exposure to market rate risk for changes in interest rates relates primarily to our investment portfolio. We do not use derivative financial instruments in our investment portfolio. By policy, we place our investments with high quality debt security issuers, limit the amount of credit exposure to any one issuer, limit duration by restricting the term, and hold investments to maturity except under rare circumstances. We classify our cash equivalents or short-term investments as fixed rate if the rate of return on an instrument remains fixed over its term. As of March 31, 2000, all of our cash equivalents and short-term investments are classified as fixed rate. There were no significant changes in our market risk exposures during the three months ended March 31, 2000. For further discussion of our market risk exposures, refer to Part II, Item 7A., "Quantitative and Qualitative Disclosures About Market Risk" in our Annual Report on Form 10-K for the year ended December 31, 1999. 21 ONYX PHARMACEUTICALS, INC.
