A team of specialists allocated to your study - entirely committed to finding accurately characterised, eligible patients.
MAC clinical trials volunteer dedicated  recruitment

Located in our own Dedicated Research Sites, MAC EnVision® - our Recruitment Centre uses MAC's proprietary engagement software suite to work seamlessly with all other departments ensuring that all patients and healthy volunteers are expertly pre-screened by study criteria. Working as an integrated part of the company, MAC EnVision® also facilitates the close monitoring of patients throughout the study, providing benefit to overall patient focus, understanding, care and across the planning and implementation of retention strategies. 


It is common industry knowledge that the most problematic area in conducting clinical trials is accessing, recruiting and retaining patients. Across 70% of all clinical studies independent research has shown that recruitment targets are not achieved and studies are not completed ‘on time’ and often outside estimated budgets. These failings then drive inefficiencies and issues across development strategies including protocol changes, budget extensions, and lengthy wait times for clinical data. The sponsor and patient experience significant negative knock-on effects because of these delays.

De-Risking studies with Science Driven oversight

MAC provides solutions to these problems and issues. MAC owns and operates Research Sites conducting Late Phase studies (Phase II-IV) which are able to recruit more patients, across fewer sites than studies conducted in hospitals and care trusts by individual physicians/consultants. This ‘traditional approach’ to clinical research generates few patients at a time, at each site, meaning that many more sites are needed to fulfil patient enrolment numbers.

MAC is dedicated and solely focused on the recruitment and conducting of clinical trials at our own Dedicated Research Sites. As a result, MAC will often reach recruitment targets for studies weeks before the deadline, providing Sponsors with a chance to bring their products to market and patients faster. With a potential reach of over 20 million patients  across the region where MAC’s sites are located, MAC is the largest and leading company in the UK for patient recruitment and study conduct services.

MAC's Recruitment Process:

Based on many years of patient outreach and study specific recruitment experience, patient feedback and industry analysis, the MAC EnVision®  recruitment process brings together innovative and world leading techniques, harnessing the power of the very latest proprietary digital technologies that cumulatively set MAC apart from other clinical trials companies. 

The value and importance of this process is highlighted by the continued investment and development of current strategies and the operational teams within MAC. Innovative outreach and recruitment techniques are integrated to ensure the effective identification & reach to specific patients with our streamlined process allows these patients to be recruited very quickly onto small or large scale studies (see a small selection of our Case Studies).

Well proven methods of outreach and recruitment are still used; including direct to patient correspondence, radio and print advertising. Targeted recruitment and carefully selected media determined by study criteria ensure that these traditional methods are successful. Whilst advertising does create much interest, MAC reaches our accurately characterised eligible patients through a combination of strong and long established relationships, our thorough work ethic, and years of experience.

The philosophy of the MAC clinical trial recruitment specialists allocated to your study is two-fold. To focus on patients and to deliver your clinical trial successfully.
