the progress of the development efforts of third parties with whom we have entered into license and collaboration agreements;
•
our ability to maintain our current research and development programs and to establish new research and development, license or collaboration arrangements;
•
our ability and success in securing manufacturing relationships with third parties or, in the future, in establishing and operating a manufacturing facility;
•
the costs involved in prosecuting, defending and enforcing patent claims and other intellectual property claims;
•
the cost and timing of regulatory approvals;
•
our efforts to enhance operational, financial and information management systems and hire additional personnel, including personnel to support development of our product candidates; and
•
the costs and ongoing investments to in-license and/or acquire additional technologies.
A change in the outcome of any of these or other variables with respect to the development of any of our product candidates could significantly change the costs and timing associated with the development of that product candidate. Furthermore, our operating plans may change in the future, and we may need additional funds to meet operational needs and capital requirements associated with such operating plans.
