What Illingworth Research does

Illingworth Research Group Ltd is a UK-headquartered Contract Research Organisation (CRO) that delivers patient- and site-facing clinical trial services to pharmaceutical, biotechnology, medical device and clinical research site customers. The company, founded in 2004 (firmographic data lists 1988) and operating from Farnborough with a Macclesfield-listed address, has grown organically over 20+ years to deliver in more than 45 countries and is a wholly owned subsidiary of Syneos Health.

Its offering is structured around three integrated core services: (1) Mobile Research Nursing Services, where GCP-trained nurses conduct trial visits in patients' homes, workplaces, schools, or vacation locations; (2) PatientGO Patient Concierge Services, a proprietary multi-language web and smart-device platform that coordinates participant travel, tracks out-of-pocket expenses and shortens reimbursement cycles, with de-identified usage data feeding back into sponsor cost-of-patient-burden reports; and (3) Clinical Trial Site Support, which augments site staffing with CRCs, data entry clerks, research nurses and pre-screening/recruitment specialists. PatientGO is a registered trademark and represents the company's principal proprietary technology asset.

Commercially, Illingworth runs a quote-based enterprise sales motion: services are bespoke, priced per protocol, and procured via a Request for Proposal process. Revenue is generated as professional services fees under multi-year contracts with study sponsors and clinical trial sites. Distribution is global, with delivery executed through a network of GCP-trained nurses and logistics partners. The company employs 11–50 staff per firmographic data and operates a small senior leadership team responsible for business strategy, global operations and site augmentation.
