Referral fee

The condition for a referrer to get their referral fee is that the referee is included in a Biotrial study with in-house stays. The referee shall have started a study and been dosed (randomized) for payment to the referrer to occur.

Since the referee may not qualify for the original study for which they were referred, the referral stipend will still be paid if the participant doses on any study within 12 months of the referral date.

Biotrial regularly updates a referral follow-up list with the name of referrers, referees, studies, and randomization dates. Within four weeks after each first dosing date, Biotrial will pay the referrers by check. Referrers can pick up their check or request it to be mailed.

Confidentiality and regulatory responsibilities

The referee's medical information will be securely kept and will remain confidential. Biotrial recruitment team never shares any PHI (Personal Protected Information); both personal or medical information remains confidential and is not shared with referrers.

The referee will be made aware that their referrer will receive payment of a referral fee based on the referee’s participation and may incidentally receive information about the status of the referee's participation in our studies.

Biotrial has the right to change, amend, or terminate this referral program at any time and will update all related communications accordingly. Biotrial Refer-a-Friend program and any change or amendment of this program requires IRB approval.
