Dr. Cong Chen is Executive Director of Early Oncology Development Statistics at Merck & Co., Inc. He joined Merck in 1999 after graduating from Iowa State University with a Ph.D. in Statistics. He also holds an MS degree in Mathematics from Indiana University at Bloomington and a BS degree in Probability and Statistics from Peking University, PR China.
As head of the group, he oversees the statistical support of oncology early clinical development and translational biomarker research at Merck. Prior to taking the role in March 2016, he led the statistical support for the development of pembrolizumab (KEYTRUDA), a paradigm changing anti-PD-1 immunotherapy, and played a key role in accelerating its regulatory approvals.
He is a Fellow of American Statistical Association, an Associate Editor of Statistics in Biopharmaceutical Research, a member of Cancer Clinical Research Editorial Board and a leader of the DIA Innovative Design Working Group. He has published over 100 papers and 10 book chapters on design and analysis of clinical trials, has given multiple short courses on the subject at statistical conferences and was invited to give oral presentations at multiple medical conferences on design strategies for oncology drug development.
Dr. Eric (Pingye) Zhang is an associate director of Biostatistics at BeiGene supporting Hematology clinical trials. Before joining BeiGene, he worked as a statistician at Merck supporting late-stage Oncology trials for pembrolizumab (KEYTRUDA) in renal cell carcinoma, NSCLC and Head & Neck cancer. He obtained a PhD degree in Biostatistics from University of Southern California in 2016. His research interests include adaptive design, subgroup analysis and basket trial design and analysis. He is leading a sub-team in the DIA Innovative Design Working Group for research on 2-in-1 adaptive design with dose selection.
The 2-in-1 adaptive design [Chen et al. 2018] is an adaptive design strategy that allows a study to choose the optimal path to success based on interim trial data, often without any need to pay the penalty for adaptation. In particular, when it is applied to an adaptive randomized-controlled Phase 2/3 oncology trial, the data at end of Phase 2 can be analyzed at the full alpha level in case of no expansion to Phase 3, or at end of Phase 3 at the full alpha level in case of expansion. As FDA has repeatedly expressed growing interest in relying more on randomized-controlled trial data for regulatory decisions, a positive Phase 2 outcome may be used to justify for accelerated approval, while a positive Phase 3 outcome can be naturally used to justify for regular approval. This new perspective provides a much-needed safety net in case of a false No-Go decision to Phase 3. The endpoint used for expansion decision can be the same as or different from the primary endpoints, and there is no restriction on the expansion bar. Due to its flexibility and robustness, the design has drawn tremendous attention to academic researchers and industry practitioners.
In this short course, we will review the history of the 2-in-1 design in the context of evolving oncology drug development paradigm, survey the current landscape of the research field, and shed light on its future directions. We will also present case studies of its applications and discuss practical issues.

Drug development is a long and costly process. Developing a new prescription drug that gains marketing approval can take many years and is estimated to cost drugmakers $2.6 billion according to recent studies. Advanced statistical analysis and machine learning hold great promise to significantly accelerate the process of drug discovery, by analyzing data generated in the biomedical domain such as bioassays, chemical experiments, and biomedical literature. Real world data (RWD), such as electronic health records (EHR), contain routinely collected practice based evidence for real world patients and thus encode insights about efficacy and safety of treatments which are invaluable for drug development. However, RWD are really massive, which poses great challenges for computational analysis. In this short course, we will provide an overview to where and how RWD can help with drug development, key techniques and methodological advancements for analyzing RWD, as well as challenges and future directions. This short course can serve as introduction materials for data scientists interested in RWD analysis for drug development as well as drug development practitioners interested in relevant machine learning techniques.

Students will learn concepts and methods for
In this course, we will introduce transportability methods for extending inferences about causal effects from a randomized trial to a target population (e.g., the population for which approval is sought for the experimental treatment in the trial). We will also show how the methods can be extended to conduct rigorous external comparisons between the experimental treatment in the trial and other treatments not evaluated in the trial, and indirect comparisons of two experimental treatments evaluated in two separate trials against a common control treatment. We will first discuss study designs and data structures for these analyses using examples from diverse clinical areas. We will then discuss the assumptions required to estimate causal effects in the target population and perform external/indirect comparisons. We will cover different statistical methods for estimating causal effects in transportability analyses, including weighting, outcome modeling (g-formula), and doubly robust methods. We will discuss how doubly robust estimators can incorporate machine learning methods to reduce model misspecification.

Based in part on the recently published co-edited volume Statistical Topics in Health Economics and Outcomes Research (Alemayehu et al.), this short course recognizes that, with ever-rising healthcare costs, evidence generation through health economics and outcomes research (HEOR) plays an increasingly important role in decision-making about the allocation of resources. This course highlights three major topics related to HEOR, with objectives to learn about 1) patient-reported outcomes, 2) analysis of aggregate data, and 3) methodological issues in health economic analysis. Key themes on patient-reported outcomes are presented regarding their development and validation: content validity, construct validity, and reliability. Regarding analysis of aggregate data, several areas are elucidated: traditional meta-analysis, network meta-analysis, assumptions, and best practices for the conduct and reporting of aggregated data. For methodological issues on health economic analysis, cost-effectiveness criteria are covered: traditional measures of cost-effectiveness, the cost-effectiveness acceptability curve, statistical inference for cost-effectiveness measures, the fiducial approach (or generalized pivotal quantity approach), and a probabilistic measure of cost-effectiveness. Illustrative examples are used throughout the course to complement the concepts. Attendees are expected to have taken at least one graduate level course in statistics.
To understand and critique the major methodological issues in outcomes research on the development and validation of patient-reported outcomes, traditional meta-analysis and network meta-analysis, and health economic analysis.

Pediatric drug development often faces substantial challenges, including economic, logistical, technical, and ethical barriers, among others. Pediatric drug development lags adult development by about 8 years and often faces infeasibility of trials, resulting in children being a large, underserved population of "therapeutic orphans," as an estimated 80% of children are treated off-label (Mulugeta et al. in Pediatr Clin 64(6):1185-1196, 2017). Among many efforts to mitigate these feasibility barriers and as an ethical approach to minimizing exposing pediatric patients to the research risks, increased attention has been given to extrapolation; that is, the leveraging of available data from adults or older age groups to draw conclusions for the pediatric population. Recent ICH E11A harmonization on a pediatric extrapolation framework provides a clearer path forward for pediatric drug development programs leveraging some degree of extrapolation despite uncertainties. In this framework, the degree to which extrapolation can be used lies along a continuum representing the uncertainties to be addressed through generation of new pediatric evidence (Gamalo et al. 2021).
Recognizing the challenges in pediatric drug development, in 2018, the ASA Biopharmaceutical Section Pediatric Working Group (SPDPx) was chartered to serve as a forum for development, education and dissemination of statistical research and innovation, and a forum for interchange of meaningful scientific opinion across multiple disciplines to accelerate development of medicines for children. Within the SPDPx, a sub-team on pediatric extrapolation was formed to specifically focus on scientific necessity through efficient and robust innovative trial designs and analytic strategies. In this short-course, instructors from the SPDPx will provide a combination of pediatric drug development process and statistical methodologies in both efficacy and safety evaluations.
