Our objective is to discover, develop and commercialize new medicines with superior efficacy, convenience, tolerability and/or safety.

Apply our expertise in multivalency primarily to validated targets to efficiently discover and develop superior medicines in areas of significant unmet medical need. Our drug discovery efforts are based on our expertise in multivalency. Multivalency involves the simultaneous attachment of a single molecule to multiple binding sites on one or more biological targets. We believe that by applying our expertise in multivalency we can discover medicines that will be superior to many market-leading medicines by substantially improving potency, duration of action and/or selectivity.

Identify at least two structurally different product candidates in each therapeutic program whenever practicable. We believe that this can increase the likelihood of successfully bringing superior medicines to market.

Partner with global pharmaceutical companies to accelerate development and commercialization of our product candidates. Our strategy is to seek collaborations with leading global pharmaceutical companies, such as GlaxoSmithKline plc and Astellas Pharma Inc., to accelerate development and commercialization of our product candidate pipeline at the strategically appropriate time.

Leverage the extensive experience of our people. We have an experienced senior management team with many years of experience discovering, developing and commercializing new medicines with companies such as Bristol-Myers Squibb Company, Merck & Co., Gilead Sciences, Pfizer, and ICOS Corporation.

Improve, expand and protect our technical capabilities. We have created a substantial body of know-how and trade secrets in the application of our multivalency approach to drug discovery. We believe this is a significant asset that distinguishes us from our competitors. We expect to continue to make substantial investments in multivalency and other technologies to maintain what we believe are our competitive advantages in drug discovery.
