London. Europe’s Hub for Global Early-Phase Trials
Purpose-designed unit in north-west London, close to Central Middlesex Hospital, our facility specialises in early-phase trials requiring large-scale inpatient capacity, complex study designs, and integrated hospital-grade services.
A Centre of Excellence in Early-Phase Research Across the UK and Europe
With more than 30 years of continuous operation, our London site is the oldest and one of the most respected early-phase clinical pharmacology units in Europe. Since opening in 1993, we have delivered over 1,000 studies, from first-in-human trials to complex adaptive designs, for more than 100 sponsors worldwide ranging from emerging biotechs to leading global pharmaceutical companies.
34 percent of our sponsors return for additional studies, a testament to our scientific excellence, participant safety, and dependable delivery.
From London to the World: Part of the Only Unified, Global Early-Phase Network
Now part of the Nucleus Network unified, global network, HMR offers sponsors a 145-bed, purpose-built clinical pharmacology unit with integrated pharmacy, laboratory, outpatient clinic, and ward facilities. Harmonised processes, shared best practices, and coordinated project delivery across our UK, Australian, and US sites enable sponsors to start, expand, or run studies in parallel across three major regulatory regions with consistent quality and seamless execution.
