Accelsiors is a leading global and scientifically driven CRO, with 20 years of experience in the field of clinical research. We assist emerging biotech companies in overcoming the challenges a drug developer would face and support them in propelling their therapies toward the path of success.

We support and accelerate each step of the clinical drug development, from the preclinical consultation stage, throughout the whole clinical development, until regulatory submission for marketing authorization. We successfully combine our experience, the flexibility, and the agility of a mid-sized CRO, with wide patient access and global service operations.

With headquarters in Switzerland and established presence in 24 countries, through subsidiaries and with operational capabilities in over 40 countries, Accelsiors covers a broad range of therapeutic areas throughout all the phases of a trial.

We are driven by science and guided by our experience to effectively support our clients in managing the complexity of clinical research. We bring together, tomorrow’s life-changing treatments.
