Trusted Partners

We work with a trusted, select group of partners for their experience, their reliability and most importantly because they offer the same quality of service and commitment to client satisfaction as ESMS Global.

“ESMS, a spin-out from Guy’s Hospital Poisons Unit, provides a unique service to clinical trials that goes beyond a simple unblinding service of the type that an NHS on-call pharmacist might provide.
This service is designed to prevent inappropriate unblinding as in most cases, the A&E doctor is confident to proceed with the patient`s treatment without unblinding, thus improving patient retention and reducing the need for higher patient recruitment.
Retaining patients on study is also crucial to the success of the grant.”
