Russia
According to the FDA Report, Russia placed in the top 10 and ranked 2nd after the U.S. in terms of the number of subjects recruited. Russia is the world's 9th country by population (146 mln people), making it a patient pool more than sufficient for a study in almost any indication.
Spain
Today 145,000 patients are involved in 3,400 clinical trials in progress in Spain. While one out of three trials carried out in Europe already has Spanish participation, the country accounts for a 4.3% share of the global clinical trials activity with oncology as the leading therapeutic area.
Bulgaria
In 2014-2019 Bulgaria was placed in the top 10 and ranked 8th in terms of the number of subjects recruited for studies according to the recent US FDA Report. 13 out of 50 novel drugs approved by the FDA in 2021 underwent studies in Bulgaria.
Poland
Poland is 10th place in the world by number of research sites (over 1,400). With a population of 38.5 mln people, it boasts successful recruitment rates, reasonable grants, and lower costs per patient than in the U.S., though higher than in Ukraine, Russia or Georgia.
Latvia
Being an EU member since 2004, Latvia boasts a harmonized regulatory and legislative environment for international clinical trials. The majority of studies fall within the therapeutic areas of oncology, neurology, psychiatry, and endocrinology.
Belarus
Belarus is a promising new player. Clinical research professionals are very particular about adhering to GCP standards. Local rules and standards are very close to those mandated by FDA and EMA.
Ukraine
Recruitment shows a significant number of eligible patients, including treatment-naïve ones. According to the MoH of Ukraine, leading therapeutic areas in 2020 are Oncology, Psychiatry, Neurology, Gastroenterology, and Hematology. The RA process takes up to 60 calendar days.
Turkey
Turkey is gaining recognition as a notable clinical research hub. The 2020 EFPIA report placed the country at 26th worldwide for its volume of clinical trials. Turkey played a key role in the development of 4 out of 37 drugs that received FDA approval in 2022.

James Barder
CEO, Futura Medical

The study has been going on during challenging times, and I am proud of our joint recruitment efforts with OCT Clinical. Without their resilience, energy, amazing control, efficiency and cooperative approach we wouldn’t have got here so soon.
