Dr. Brian Hobbs joined Cleveland Clinic as Associate Staff and Section Head of Cancer Biostatistics in the Lerner Research Institute in 2017. He holds a joint appointment in Cleveland Clinic’s Taussig Cancer Institute. He also serves as Co-Director of the Biostatistics and Bioinformatics Core for the Case Comprehensive Cancer Center. His methodological expertise comprises Bayesian inference, subtyping, prediction, and trial design as well as cancer radiomics. Before joining Cleveland Clinic, Dr. Hobbs was a tenured Associate Professor in the Department of Biostatistics at The University of Texas MD Anderson Cancer Center in Houston, Texas. In 2010, he completed a doctoral degree in biostatistics at the University of Minnesota and then joined MD Anderson as a postdoctoral fellow. Eastern North American Region of International Biometric Society selected his thesis paper for the John Van Ryzin Award in 2010. In 2016, Dr. Hobbs was selected by The University of Minnesota for the Emerging Leader Award, an honor bestowed on alumni on the basis of impactful contributions within 10 years of graduating from one of The School of Public Health’s 20 programs. In 2017, Dr. Hobbs was invited to lead the publication of National Cancer Institute’s Clinical Trials Design Task Force with the goal of providing national, consensus recommendations for first-in-human cancer drug trials that use seamless designs.

Statistics Expert Leads National Clinical Trials Task Force

Breakthroughs in cancer biology have defined new research programs emphasizing the development of therapies that target specific pathways in tumor cells or promote anti-cancer immunity. Innovations in clinical trials have followed with statistical designs devised to consolidate traditional phases of oncologic drug development as well as facilitate inclusive eligibility and evaluations of multiple indications. These so-called “seamless” trial designs have many potential benefits but have not yet been objectively considered.
