We used cash of $17.9 million and $14.4 million for our operating activities in the quarters ended March 31, 2002 and 2001, respectively. Investing activities used $35.6 million in the quarter ended March 31, 2002 and provided $18.7 million in the quarter ended March 31, 2001. Investing activities in both periods consisted primarily of purchases and sales of short-term investments, purchases of laboratory and office equipment and increases in patents. Financing activities provided $92.2 million and $0.2 million in the quarters ended March 31, 2002 and 2001, respectively. These amounts consist of proceeds from the sale of common stock, offset by payments on capital leases and notes payable. The majority of the cash provided from financing activities in the quarter ended March 31, 2002 was the public offering of common stock for net proceeds of approximately $90.7 million. Our use of cash for our operating activities in the quarter ended March 31, 2002 was $17.9 million, and is approximately $4.2 million less than our net loss of $22.1 million. This is due primarily to an increase in our current liabilities of approximately $3.2 million and non-cash expenses of approximately $1.9 million, partially offset by inventory purchases of approximately $0.9 million. The increase in current liabilities reflects the timing of cash payments for services rendered in connection with our ongoing clinical studies, primarily the Phase 3 studies for AC2993. We do not expect our current liabilities to continue to grow at this same rate in the subsequent quarterly periods in 2002. Additionally, we expect that our cash expenditures to conduct clinical trials will increase during the remainder of 2002, due primarily to the AC2993 Phase 3 program. We also expect to increase our expenditures for AC2993 LAR, which is planned to enter Phase 2 evaluation in the second quarter of 2002. Until the timing of the FDA’s determination regarding the approval of SYMLIN becomes more certain, we do not expect expenditures for general and administrative expenses to change materially. We do intend to continue with certain pre-marketing activities related to the planned commercialization of SYMLIN, however, the larger cash expenditures associated with the hiring and deployment of a SYMLIN sales force and increased costs for marketing activities are dependent upon the approval of SYMLIN by the FDA. If it appears that FDA approval will be delayed significantly or not received at all, we expect to further re-evaluate our level of activity and cash expenditures associated with the planned commercialization of SYMLIN. At March 31, 2002, we are committed to purchase approximately $4.0 million of commercial grade bulk drug material in the subsequent twelve-month period. If FDA approval for SYMLIN is received, our expenditures to secure commercial grade bulk drug material will increase substantially, including a commitment to purchase approximately $9.2 million of additional material pursuant to an agreement with Johnson & Johnson. We are also obligated to purchase this material if we enter into a collaboration agreement for SYMLIN or if there is a change in control of the Company. If none of these events occur, we have no obligation to purchase this material from Johnson & Johnson. In 2001, several class action lawsuits were filed against us and certain of our officers and directors alleging securities fraud in connection with various statements and alleged omissions relating to the development of SYMLIN. These lawsuits were consolidated into a single action. If we are not successful in our defense of this lawsuit, we may be required to make significant payments to our stockholders. The lawsuit is at an early stage and the extent or range of possible damages, if any, cannot yet be reasonably estimated. We do not expect to generate a positive internal cash flow for at least the next few years due to additional research and development costs, including costs related to research, preclinical testing, clinical trials, manufacturing costs, and general administrative expenses necessary to support such activities. We intend to use our existing financial resources for continuing costs associated with preparing for the planned commercialization of SYMLIN, the continuation and potential expansion of our other research and development programs, including the clinical development of SYMLIN, AC2993, AC2993 LAR and AC3056, and related general and administrative support. Research and development expenses will include costs of supplying materials for and/or conducting clinical trials. The amounts actually expended for each purpose may vary significantly depending upon numerous factors, including the progress of our research and development programs, the results of preclinical and clinical studies, the timing of regulatory submissions and approvals, and, if approvals are received, time to market thereafter, technological advances, determination as to the commercial potential of our product candidates and other preclinical compounds currently under development, and the status of competitive products. Expenditures will also depend upon the availability of additional sources of funds, the establishment of commercial or collaborative arrangements with other companies, and other factors. 10 |
