Traditional clinical trials can present challenges and risks around patient engagement and retention, and site costs including:   

• Patient drop-outs due to site travel challenges;
• Patient drop-out rates can result in additional expenses associated with recruitment timeline extensions or new site activations; and 
• Cost and time impacts around transfer of data from on-site documents to electronic databases.

Virtual trials, also known as decentralized, remote or site-less clinical trials, offer an alternative, cost efficient and patient centric solution, alleviating the abovementioned potential risks and challenges.
