In Croatia, the Pliva research team in Zagreb developed azithromycin (Sumamed) in 1980, now one of the most widely used antibiotics worldwide.

Excellence in Medical Care
Croatia consistently ranks among the world’s leaders in organ donation and transplantation per capita, demonstrating exceptional medical organisation, outcomes, and donor participation.

Strong centralised healthcare systems with specialised or referral centres enable efficient access to well-defined patient populations, making recruitment faster and more organised.

Motivated Patients & Study Teams
Inspired by public health pioneers such as Andrija Štampar, Croatia and Slovenia foster high patient trust and participation. Study teams are equally committed, bringing expertise and dedication to support medical innovation and better treatment outcomes.

Experienced Investigators
Clinical trials are conducted by experienced physician investigators and highly skilled study teams. Many bring international exposure through education and collaboration, contributing to high scientific standards and smooth execution of global clinical trials.
