According to GCP, whilst the Sponsor is responsible for supplying trial materials in accordance with Good Manufacturing Practice, the Investigator is actually made responsible for the control of trial drugs.
Where however, the trial location is in a hospital, it is usual for the hospital Pharmacist to take responsibility for the storage, dispensing and reconciliation of all clinical trial supplies, and keeping up to date and accurate records.
When the trial is conducted with physicians in office
practice (general practitioners etc.), it is the Investigator who
fulfills the Pharmacist's role.
