FAQs for Sponsors

Which studies are the best fit for PR?

Outpatient studies are best suited for PR's network. Our network sites are community practices including  both general and special  practices ( diabetes, dermatology, sleep, COPD, etc) . This provides access to rich database of patients. Participation is higher due to vicinity of sites to patients' homes and continuity of care. If capacity is not available, a bespoke network for your study can be built in approximately six months.

How does PR accurately forecast enrolment?

We have partnered with UK based Clinical trials platform, TriNetx. TriNetX is a machine learning platform that accesses each network site's EHR and queries it based on your inclusion/exclusion criteria. By using real practice data, we deliver accurate enrolment estimates and tailored recruitment strategies.

Our patient recruitment team partners closely with site coordinators and practice managers through the recruitment window to execute on these strategies and achieve projections.

How does Plexus Research streamline site operations?

PR signs a master contract with each network site and provides training to the staff as well. All sites operate under the same contract, budget, IRB and set of SOPs. By removing negotiations and reducing variability across sites, we are able to take sites from selection to activation ~2-3x faster than industry average.


Once activated, all sites are supported by a centrally-managed research coordinator team. The team develops focused expertise in your protocol and executes activities consistently across all trial sites. By matching sites' geographic spread to the number of coordinator staffed, we are able to smooth patient visits and supporting activities across a team. This unlocks scheduling flexibility and de-risks dependencies on single individuals.


We are using a USA based, industry leading, end-to-end integrated CTMS which provides CTMS capabilities, documentation storage, Social media based recruitment and engagement , e-consenting, all in one place.

How does PR prioritize the patient experience?

PR puts the patient at the centre of our trials. Our mission of bringing new treatments to patients faster and more efficiently starts by bringing trials to community practices, where patients can access investigational treatments close to home with the support of their current provider.

Once we have the right sites, we conduct in-depth patient research to align our recruitment strategy with patient motivators and detractors. This approach helps us engage the right patients- those who are a good fit for the protocol and who can commit to full participation.

PR provides centralized recruitment support to all sites in a study. Doing so allows us to optimize digital recruitment campaigns within a geography, apply patient engagement best practices across sites, and smoothly coordinate patient logistics.

What is the profile of a typical PR investigator?

Most of our investigators are community practitioners based in small-to-midsize practices. All are interested in research - and some have served as investigators in the past. PR has provided GCP training to these practitioners to work as Sub-Investigators.

PR breaks down barriers by providing practices with the necessary training, equipment, staff and recruitment support. If selected for a study, the site receives centralized team support so that they are fully equipped to meet the quality and performance expectations.
