minimum volume requirements, exclusivity arrangements or other restrictions. We may not be able to enter into long-term agreements on commercially reasonable terms, or at all. If we change to other manufacturers, the FDA and comparable foreign regulators must approve these manufacturers’ facilities and processes prior to use, which would require new testing and compliance inspections, and the new manufacturers would have to be educated in or independently develop the processes necessary for the production of our product candidates.
 
The manufacture of pharmaceutical products requires significant expertise and capital investment, including the development of advanced manufacturing techniques and process controls. Manufacturers of pharmaceutical products often encounter difficulties in production, particularly in scaling up initial production. These problems include difficulties with production costs and yields, quality control, including stability of the product candidate and quality assurance testing, shortages of qualified personnel, as well as compliance with strictly enforced federal, state and foreign regulations. If our manufacturers were to encounter any of these difficulties or otherwise fail to comply with their obligations to us, our ability to provide product candidates to patients in our clinical trials would be jeopardized. Any delay or interruption in the supply of clinical trial supplies could delay the completion of our clinical trials, increase the costs associated with maintaining our clinical trial program and, depending upon the period of delay, require us to commence new trials at significant additional expense or terminate the trials completely.
 
In addition, all manufacturers of our products must comply with cGMP requirements enforced by the FDA through its facilities inspection program. These requirements include, among other things, quality control, quality assurance and the maintenance of records and documentation. Manufacturers of our products may be unable to comply with these cGMP requirements and with other FDA, state and foreign regulatory requirements. We have little control over our manufacturers’ compliance with these regulations and standards. A failure to comply with these requirements may result in fines and civil penalties, suspension of production, suspension or delay in product approval, product seizure or recall, or withdrawal of product approval. If the safety of any product supplied is compromised due to our manufacturers’ failure to adhere to applicable laws or for other reasons, we may not be able to obtain regulatory approval for or successfully commercialize our products, and we may be held liable for any injuries sustained as a result. Any of these factors could cause a delay of clinical trials, regulatory submissions, approvals or commercialization of our product candidates, entail higher costs or result in our being unable to effectively commercialize our products. Furthermore, if our manufacturers fail to deliver the required commercial quantities on a timely basis and at commercially reasonable prices, we may be unable to meet demand for our products and would lose potential revenues.
 
We are combining drugs in novel combinations and cannot be sure that the combined drugs can co-exist for extended periods in close proximity.
 
Bupropion, which is an API in both Contrave and Excalia, is known to have issues with stability that require manufacturing processes which minimize exposure to moisture. In addition, bupropion is formulated with ingredients that are designed to limit oxidation. Naltrexone, which is an API in our Contrave product candidate, contains water within its crystal structure. We are performing stability testing to ensure that our combination tablet of Contrave has sufficient stability to provide the customary two-year stability characteristics and shelf life expected of a conventional pharmaceutical product. Although we are currently conducting stability studies, we cannot be sure that either Contrave or Excalia will be stable, and we may not be able to demonstrate sufficient long term stability to provide at least two years of shelf life for these product candidates, which could jeopardize our ability to bring such product candidates to market.
 
We face potential product liability exposure, and, if successful claims are brought against us, we may incur substantial liability.
 
The use of our product candidates in clinical trials and the sale of any products for which we obtain marketing approval expose us to the risk of product liability claims. Product liability claims might be brought against us by consumers, health care providers, pharmaceutical companies or others selling or otherwise coming into contact with our products. If we cannot successfully defend ourselves against product liability
