Clinical Trials Office

The Clinical Trials Office (CTO) supports the design and conduct of oncology clinical trials. The CTO is responsible for patient and study coordination-related activities, including subject evaluation and registration, toxicity assessment and safety monitoring of novel therapeutics and patient education.

The CTO works to assure patient eligibility and safety, regulatory compliance, and quality, reproducible data.
