Largest in the UK

Richmond Pharmacology is renowned for our recruitment capabilities. We maintain the largest early phase participant database in the UK with over 250,000 registered and pre-qualified volunteers willing to participate in clinical trials. We have pioneered the use of marketing and recruitment methods, our systems and long standing expertise. This allows us to adapt our recruitment efforts to efficiently screen in excess of 500 volunteers in a month to place up to 150 healthy volunteers and patients into the trials ongoing at Richmond.

Up for the challenge

Our extensive metrics and feasibility assessments offer Sponsors invaluable insight into study acceptability and suitability of the target population. This ensures accurate predictions of recruitment time and attrition rates which benefits the overall timeline planning for the trials we run. As a result, we are able to determine the recruitment effort and identify any potential challenges the study may present at an early stage development, thereby allowing time to address these challenges in a manner that will facilitate study conduct without compromising the scientific quality.

Tried and tested

Our dedicated in-house recruitment teams and personal touch ensure that volunteers are engaged from the first contact to the last appointment. Our strategic and efficient management, complemented with the ability to modify standard strategies due to the unique demands of individual trials, allows us to:

  • Gather homogeneous data with statistical significance in reduced sample size
  • Limit participant exposure to what is essential
  • Maintain a high (99%) completion rate for volunteers included in trials we run
