Cleveland Clinic's Center for Therapeutics Discovery (C3TD) aids in the identification of promising hypotheses and targets with potential to address unmet medical need and shift the standard of care. To accomplish this task, Dr. Stauffer and C3TD teams partner with investigators to identify gaps and barriers preventing forward progress towards illuminating and redirecting translational research. The most promising C3TD projects progress into a development pipeline to support IND enabling studies that can be funded through multiple models, including accelerator partnership support, startup company initiated funding, or industry sponsored research agreements.

C3TD provides expertise and services in medicinal chemistry, protein science/structural biology, screening/target validation, and drug metabolism/pharmacokinetics. We employ a number of industrially proven technologies and approaches to obtain selective, potent, and patentable chemical entities, in addition to the preparation of prior art reference compounds to investigators. These activities aid to pave the path towards in vivo proof-of-concept in accepted preclinical models and add value through various gated risk reduction studies that inform the path towards development.

Dr. Stauffer has drug discovery experience leading industry and academic teams in several therapeutic areas, including neurodegenerative disease, cancer, and cardiovascular disease. He is a co-author on over 80 peer reviewed publications and has 28 issued US patents. His chemistry interests lie in the areas of catalysis and reaction discovery as tools for problem solving in medicinal chemistry and late lead optimization. His therapeutic and research interests are broad and include protein-protein interactions, epigenetic and metabolic drug targets, allosteric modulation, and structure-based design.
