我們可能需要額外的資金，以繼續我們的研究和產品開發計劃，進行臨床前研究，臨床試驗中，都需要操作基金的費用，這些都需要為我們的產品的候選人尋求監管部門的批準，文件和起訴的專利申請，以及執行或保護專利的權利要求，如果可能的話，還有產品基金的許可和任何可能的收購。

   Based on assumed achievement of milestones covered under each agreement, the timing and payment of which is highly uncertain.

    

  We periodically assess the scientific progress and merits of each of our programs to determine if continued research and development

is commercially and economically viable. Certain of our programs have been terminated due to the lack of scientific progress and prospects for ultimate commercialization. Because of the uncertainties associated with research and development in these programs, the duration and completion costs of our research and development projects are difficult to estimate and are subject to considerable variation.
Our inability to complete research and development projects in a timely manner or failure to enter into collaborative agreements could significantly increase capital requirements and adversely affect our liquidity.我們無法及時或未能訂立的合作協議，在完成研究和開發項目中，可能會有增加資本的要求，這對我們的資本的流動性會產生不利影響。

 

          Our cash requirements may vary materially from those now planned because of results of research and development and product#p#分頁標題#e#

testing, changes in existing relationships or new relationships with licensees, licensors or other collaborators, changes in the focus and direction of our research and development programs, competitive and technological advances, the cost of filing, prosecuting, defending and enforcing patent claims, the regulatory approval process, manufacturing and marketing and other costs associated with the commercialization of products following receipt of regulatory approvals and other factors.

 

        The above discussion contains forward-looking statements based on our current operating plan and the assumptions on which it relies. There could be deviations from that plan that would consume our assets earlier than planned.Off-Balance Sheet Arrangements and Guarantees

 

           We have no obligations under off-balance sheet arrangements and do not guarantee the obligations of any other unconsolidated entity.我們沒有義務保持債務平衡，不保證承擔任何其他未合并實體的義務。
