About us


Founded in 2005 by Prof. Esteban Cvitkovic, Oncology Therapeutic Development (OTD) is a Paris-based boutique CRO spin-off from a former oncology-specialist CRO. The two major axes of our small and highly experienced team overseen by Prof. Cvitkovic, are the Clinical and Consulting groups, with an infrastructure of medical oncologists, project managers, and CRAs, supported by medical writing and admin staff. The team collaborates actively with data management, statistics, and PK/PD groups, as well as regulatory experts. Our strength lies in our diverse backgrounds, extensive oncology experience and high-level training.
