These statements are based upon management's current expectations and are subject to risks and uncertainties, known and unknown, which could cause actual results and developments to differ materially from those expressed or implied in such statements. Such known risks and uncertainties relate to, among other factors: the risk that Adolor may not obtain FDA approval for the NDA for Entereg(R) in POI, whether due to the risk that: Adolor is not able to provide additional data satisfactory to the FDA to obtain approval for the NDA; Adolor is not able to justify that the median reduction in time to gastrointestinal (GI) recovery seen in bowel resection patients treated with Entereg(R) is clinically meaningful; the adequacy of the results of the Studies 14CL302, 14CL306, 14CL308, 14CL313 and 14CL314 to support FDA approval of Entereg(R), the results from other clinical trials of Entereg(R), including the Glaxo Phase 3 Study 001, the adequacy of the development program, the conduct of the clinical trials, changing regulatory requirements, different methods of evaluating and interpreting data, reliance on third party manufacturers, adverse safety findings or otherwise; the risk that the FDA may not agree with Adolor's analyses of Studies 14CL302, 14CL306, 14CL308, 14CL313 and 14CL314 and may evaluate the results of these studies by different methods or conclude that the results from the studies are not statistically significant, clinically meaningful or do not support safety or that there were human errors in the conduct of the studies or otherwise; the risk that the results of any one or all of the Entereg(R)(alvimopan) clinical studies SB-767905/012, SB-767905/013, SB-767905/014 and SB-767905/008 are not positive; the risk that regulatory approvals for the use of alvimopan in patients taking opioids for persistent pain are not achieved; the risk that the results of Study 001 do not support a submission of a marketing approval application for alvimopan in Europe for POI; the risk of unfavorable results of trials in other indications; the risk that filing targets for regulatory submissions are not met; the risk that FDA does not remove the clinical hold on the Delta IND; the costs, delays and uncertainties inherent in scientific research, drug development, clinical trials and the regulatory approval process; Adolor's history of operating losses since inception and its need for additional funds to operate its business; Adolor's reliance on its collaborators, including Glaxo, in connection with the development and commercialization of Entereg(R); market acceptance of Adolor's products, if regulatory approval is achieved; competition; and securities litigation.
