proof of concept trials

ARENSIA delivers high degree of scientific and logistical expertise for Phase I/Ib/IIa and PROOF OF CONCEPT patient studies.



phase i special populations

ARENSIA offers exceptional fast recruitment rates for renal and hepatic impaired patients.



regulatory process

ARENSIA has the know-how to successfully manage the regulatory process in various Eastern European countries.



The healthcare system in Eastern Europe is highly centralized with well-documented patient files. Efficient networking and an in-depth understanding of the healthcare systems in the countries we work in is a key factor for rapid recruitment.

At our Exploratory Medicine Units we recruit patients through the following channels:

  • Patients in the database of the hospitals where our units are located in
  • New patients, which come on daily basis as seen by the investigators in our teams
  • Patients managed by a trusted network of collaborating physicians (from other hospital & clinics in a radius of up to 200 km)

Each ARENSIA unit has a dedicated team of recruitment managers, overseeing a large network of collaborating physicians.

The success of our recruitment is guaranteed by a very close collaboration with these well selected collaborating physicians. This network is consistently and continuously being built up enlarged across therapeutic areas such as immunology, oncology, cardiovascular, metabolic, respiratory, GI, dermatology, nephrology, viral diseases, hepatology, neurology, enabling us to deliver exceptional fast recruitment rates incl. biological/treatment naïve patients.

The basis for reliable recruitment commitments at ARENSIA originates from a very thorough feasibility process. This process is performed by a detailed analysis of the available patient pools by our dedicated medical teams, closely involving the network of collaborating physicians. For each trial ARENSIA establishes a tailor-made recruitment strategy which depends on the particularities and design of the trial. This ensures that every trial is performed within the timelines initially estimated and agreed with the Sponsor.

Healthy volunteers (as control groups to Phase I studies in renal/hepatic impaired patients) usually are recruited by word of mouth.

Based on specific in/exclusion criteria, we are glad to offer our Sponsors concrete and reliable estimations on recruitment rates within a trial feasibility process.

ARENSIA rejects a project if our feasibility results that the trial design or patient population cannot be performed, respectively enrolled at our sites. ARENSIA's reputation is based on reliability: we give realistic planning which we fulfill.
