History

Simbec Research Ltd. is a United Kingdom clinical research organisation based in Merthyr Tydfil, Wales. According to its own corporate communications, the company has been delivering clinical trial management services for almost five decades, placing its origins in the late 1970s or early 1980s. Over that period it developed into a full-service contract research organisation (CRO) capable of running studies from first-in-human and Phase I through to Phase III. The company built its reputation on clinical pharmacology and early-phase research, operating a purpose-built facility where it conducts all types of studies, with the majority of its work involving investigational medicinal products across all drug delivery routes. Its service range expanded to include central laboratory services, bioanalytical laboratory services, routine safety testing, immunoassays, clinical and medical writing, and early regulatory support, alongside full clinical trial management. Simbec-Orion developed particular expertise in challenging therapeutic areas, including oncology, rare and orphan diseases, respiratory medicine, dermatology, vaccines and anti-infectives. It positioned itself as a specialist partner for small and mid-size drug developers, offering tailor-made and scalable solutions with a centralised leadership team. At some point the business became part of the Caidya group, a global clinical research organisation, and now operates under the Simbec-Orion name as a Caidya® company. Under this ownership, Simbec-Orion continues to deliver early- to late-phase clinical trials globally, maintaining its specialist focus on rare diseases and oncology while benefiting from the broader capabilities of the Caidya group. The company emphasises stable teams, reporting an attrition rate of under 10% and noting that many colleagues have spent much of their careers with the organisation.
