Don Berry, Ph.D. / Founder & Senior Statistical Scientist
Donald Berry is Founder of Berry Consultants, LLC, and a professor in the Department of Biostatistics of the University of Texas M.D. Anderson Cancer Center. He was founding Chair of this department in 1999. Dr. Berry received his Ph.D. in statistics from Yale University, and previously served on the faculty at the University of Minnesota and at Duke University. He has held endowed faculty positions at Duke University and M.D. Anderson.
Dr. Berry is a well known developer of statistical theory and methodology. He has designed and supervised the conduct of hundreds of innovative clinical trials, including Bayesian adaptive trials in cancer and other diseases. He has developed Bayesian adaptive designs that efficiently use information that accrues over the course of the trial. These trials minimize sample size while increasing the likelihood of detecting therapeutic activity. A principal focus of his research is the use of biomarkers for learning which patients benefit from which therapies, based on molecular markers and phenotype. In particular, he designed and is a co-PI of I-SPY 2 in high-risk early breast cancer, a trial that was the focus of the two lead articles with two editorials in the July 2016 NEJM. He has designed Phase 3 Bayesian adaptive platform clinical trials in glioblastoma, GBM-AGILE and pancreatic cancer.
Scott Berry, Ph.D. / President & Senior Statistical Scientist
Scott Berry is President and a Senior Statistical Scientist at Berry Consultants. He earned his MS and PhD in statistics from Carnegie Mellon University and was an Assistant Professor at Texas A&M University before co-founding Berry Consultants in 2000. He has led Berry Consultants to be widely regarded as the premier Bayesian consulting company in the world. Since 2000, he has been involved in the design of hundreds of Bayesian adaptive clinical trials of pharmaceuticals and medical devices and has become an opinion leader in the field of Bayesian adaptive clinical trials. Some of these trials have been groundbreaking trial designs, setting new standards for innovation and flexibility in trial design. These include the trials supporting the first fully Bayesian approval by the center for drug evaluation of the United States FDA (Pravastatin-Aspirin combination) and the statistical design for Time Magazine’s #2 Medical Breakthrough of 2007 (Veridex’s GeneSearch BLN Assay).
