There are a lot of factors that can influence whether clinical trials should be outsourced or insourced. One could be the size of the company. Say a small company wanted to perform clinical trials, it wouldn’t be reasonable for them to do it on their own if they don’t have the capabilities. Rather it would be more cost-effective if it was outsourced and have other people who are more capable and effective to do the work. It is also important to ensure that the organization running the clinical trials are well certified. It is first important to figure out whether the depth of the clinical trials require the participation of external companies or if it’s okay to simply do it in-site. it is important to remember the capabilities of your clinical trial division and the cost that it can handle, otherwise, it would be a better idea to outsource such trials if they save more money and time.
