Probandeninfo is the participant and patient information service for CRS, which is a clinical research company. We run studies in Mannheim, Kiel and Berlin. For over 40 years, we've conducted clinical studies for pharmaceutical companies, medical device makers, and academic partners. We clearly inform you, guide you through the process, and ensure you are well cared for before, during, and after you take part.

A clinical study tests new or existing medications and medical procedures in a controlled way. The main goal is to understand how well they work and how safe they are. You are essential: without participants, new treatments cannot be approved or improved. Every study is reviewed by an independent ethics committee and government regulators before it can start.

• Healthy volunteers are people without major medical conditions who usually don’t take regular medication. They often join early studies to see how a new medicine acts in the body.
• Patient participants take part in studies focused on treating or understanding a specific medical condition they already have.
• Every study page clearly lists the criteria (the rules) for who can and cannot join.

Yes. We're happy to speak with a trusted relative or your family doctor to explain the study and answer any questions. You are free to discuss all the materials with them before you decide to join.

• The first visit is the information session. This may take place online or on-site and lasts approximately one hour.
• The screening visit (medical examination) may take up to three hours, depending on the study, as it may include blood tests, ECGs, and additional examinations.
• We'll inform you about these visits in advance so you can plan your time.
