For Theorem, offering truly global reach means more than establishing a presence — we have localized expertise you need to conduct trials of all sizes and complexity worldwide. Whether it’s scaling up your staff to accommodate a global undertaking, enhancing patient recruitment in targeted areas, providing region-specific regulatory expertise or anything else, the solutions we offer are never compromised for lack of local understanding. All Theorem employees are fluent in English and are equipped with powerful communication and collaboration tools that work in real time, which means your trial can advance regardless of time zone and language barriers.

  • Staff in 40+ Countries
  • Offices in 30+ Countries
  • Access to 22,000+ Investigator Sites
  • Strategic Alliances With Industry Leaders

Vendor Partners

Theorem is a full-service CRO; however, we also partner with subcontractors and vendors on an as-needed basis to deliver solutions in the most effective and efficient manner possible. Theorem has relationships with vendors specializing in interactive voice response systems (IVRS), central laboratory services, electronic data capture (EDC), translation services, drug and product development services, patient recruitment services, electrocardiogram (ECG) measurements, international investigator meeting coordination and many other areas. We’ve established a cross-departmental vendor management committee to direct the selection, qualification and oversight of selected vendors and maintain our network.

Strategic Alliances

Theorem has established strategic alliances with the best in the industry. With every alliance we forge, we put the infrastructure in place to make the work happen effectively and efficiently as possible to deliver what’s best for your budget, timelines and outcomes.
