Regional and Global CNS Feasibility Expertise

Timely CNS study delivery depends on precise site selection. PSI enhances decision-making with access to site historical performance, operational capacity, and recruitment potential by indication through SYNETIC™, part of PSI’s INTELIA™ clinical trial planning platform. SYNETIC™ helps find the best mix of high-performing sites for your protocol.

Our feasibility assessments go beyond the basics to provide a full picture of site performance and landscape, including:

  • Target population availability and limiting factors
  • Standards of care
  • Competitive studies
  • Regulatory climate
  • Access to Key Opinion Leaders

With a database of proven neurology sites offering significantly higher enrollment rates and the advanced VISIONAL™ study modeling solution, PSI makes it easier than ever to select the optimal sites and geographies for your program. Our unique combination of data-driven site selection and predictive modeling maximizes your study’s visibility and potential for success.

Strong Site Relationships and Support

It’s not enough simply to identify the right sites — you need to know how to work with them as well. This includes investing in training and dedicated support for successful patient enrollment and retention. PSI’s approach centers on long-term partnership, consistent support, and shared goals, ensuring that sites view your study as a priority and are committed to its success. Our full-service site support includes:

  • Providing integrated rater training
  • Regular onsite and remote training on study protocols and patient interaction to efficiently meet study requirements
  • Comprehensive study manuals and quick-reference guides for consistent execution
  • Digital communication tools for real-time updates and speedy problem-solving
  • 24/7 dedicated support teams to quickly address urgent issues and avoid delays
  • Advanced data systems for seamless data management, reducing errors and ensuring real-time accuracy
  • Recruitment strategies refined through demographic and site-specific analysis to boost enrollment and retention
  • Tailored imaging assistance for high-quality operations
  • Optimizing patient pathways for each site and patient group
  • Assisting with site-specific startup activities, including reviews, approvals, and contract negotiations
  • Coordination with central and local labs for clear guidance and investigator training on storage and logistics

A Forward-Thinking Approach to Neurology Research

Technological advances, evolving patient needs, and increasing competition are driving significant changes in the neurology research landscape. Each requires careful attention to trial design, geography, and patient enrollment; a trial for a biosimilar is very different from that for a novel gene therapy drug, but delivering it can be just as challenging.

Your study deserves a CRO committed to understanding and navigating these complexities. PSI stands out with expertise spanning global 10-year CNS programs, biosimilar studies, and specialized teams dedicated to cell and gene therapy and radiopharmaceutical studies. Our neurology experts have the answers to help you enroll your study as quickly and efficiently as possible while ensuring quality and consistency.
