This press release contains forward-looking statements regarding the progress of the Company's clinical trials, including its Phase 2 trial with ARQ 197 in non-small cell lung cancer (NSCLC) and trials which may be conducted by Daiichi Sankyo and/or Kyowa Hakko Kirin under their agreements with the Company. These statements are based on the Company's current beliefs and expectations, and are subject to risks and uncertainties that could cause actual results to differ materially. Positive information about early stage clinical trial results is not necessarily indicative of clinical efficacy and does not ensure that later stage or larger scale clinical trials will be successful. For example, ARQ 197 may not demonstrate promising therapeutic effect; in addition, this compound may not demonstrate an appropriate safety profile in further pre-clinical testing and in current, later stage or larger scale clinical trials as a result of known or as yet unanticipated side effects. The results achieved in later stage trials may not be sufficient to meet applicable regulatory standards. Problems or delays may arise during clinical trials or in the course of developing, testing or manufacturing these compounds that could lead the Company or its partner to discontinue development. Even if later stage clinical trials are successful, the risk exists that unexpected concerns may arise from analysis of data or from additional data or that obstacles may arise or issues be identified in connection with review of clinical data with regulatory authorities or that regulatory authorities may disagree with the Company's view of the data or require additional data, information or studies. In addition, the planned timing of initiation and completion of clinical trials for ARQ 197 are subject to the ability of the Company or Daiichi Sankyo, its partner, and Kyowa Hakko Kirin, a licensee of ARQ 197, to enroll patients, enter into agreements with clinical trial sites and investigators, and other technical hurdles and issues that may not be resolved. Moreover, Daiichi Sankyo has certain rights to unilaterally terminate the ARQ 197 license, co-development and co-commercialization agreement. Drug development involves a high degree of risk. Only a small number of research and development programs result in the commercialization of a product. Furthermore, ArQule may not have the financial or human resources to pursue drug discovery successfully in the future. For more detailed information on the risks and uncertainties associated with the Company's drug development and other activities see the Company's periodic reports filed with the Securities and Exchange Commission. The Company does not undertake any obligation to publicly update any forward-looking statements.
