Experienced team

OCT is a team of over 200 clinical trial services professionals. Our clinical department consists of highly qualified specialists with medical, pharmaceutical
and chemical backgrounds. OCT is
managed by experienced clinical research experts who have contributed to the company’s development and growth
since its beginning.

Support and communication

The OCT team is always easy to reach:
we are an email or a phone call away and always respond within 24 hours. We
provide consulting on clinical trial strategy and design, site management and patient engagement solutions, regulatory and logistics support and timely updates on clinical trial progress.

Global Standards Compliant Studies

OCT works in full compliance with international standards (ICH GCP) and FDA/EMA requirements. Since 2005, we
have been guiding our sponsors through
the intricacies of conducting clinical trials
in Eastern Europe, both when dealing with the Ministry of Health of Russia and FDA or EMA. We have also developed our own
set of SOPs, which are regularly updated
by our Quality Assurance department.

Risk-management Approach

Our goal is to provide sponsors with full transparency from the first inquiry to the final step of the study. Prior to the project’s start, we conduct a thorough analysis and weigh of all the potential risks that might arise during the study, and prepare a risk management plan. In case risks occur, all the parties concerned are immediately informed and actions are taken in accordance with the plan.
