A Network of Early-Phase Clinical Research Environments
Accelsiors works with closely collaborating early-phase clinical research units across Europe. These environments are selected and maintained for their scientific capability, regulatory track record, investigator expertise, and operational reliability.
Each unit offers a distinct profile — in terms of infrastructure, therapeutic focus, participant access, and integration with broader clinical and academic ecosystems. This allows Accelsiors to match each programme to the setting that best supports its specific requirements.
A key feature of several of our collaborating environments is their integration within tertiary healthcare institutions. This hospital-embedded model provides advantages that are difficult to replicate in standalone Phase I units:
- Direct access to both healthy volunteer and patient populations
- Proximity to specialist clinical departments — including pediatric, oncology, cardiology, neurology, and metabolic medicine — enabling patient referral and investigator collaboration within the same institution
- Hospital-grade infrastructure for safety monitoring, including overnight stays, intensive PK/PD sampling, and medical emergency response
- Pediatric clinical departments and pediatric investigators within the same institution, supporting early-phase pediatric studies with the oversight, ethical governance, and clinical expertise that these programmes require
Regulatory and ethics pathways established within European frameworks, including experience with pediatric-specific regulatory submissions
Hospital-integrated clinical research in Thessaloniki, Greece
One of our closely collaborating environments is embedded within a public tertiary hospital in Thessaloniki, Greece. This setting provides:
- Direct access to both healthy volunteer and patient populations
- Hospital-grade infrastructure for safety monitoring, including overnight stays and intensive PK/PD sampling
- Proximity to specialist clinical departments, including pediatric departments, for patient-based and pediatric early-phase studies
- A research team with deep experience in Phase I and early Phase II execution
- Regulatory and ethics pathways established within the Greek and European frameworks
This environment is particularly well-suited for FIH studies requiring close medical oversight, biomarker-intensive protocols, studies bridging healthy volunteer and patient populations, and, notably, pediatric early-phase studies where hospital-integrated pediatric expertise is essential.
It is one example of how Accelsiors connects sponsors with the right research environment, not as a referral, but as an integrated part of the clinical development program.
