| Bayesian Hierarchical Models for Subgroup Analysis | In conventional subgroup analyses, subgroup treatment effects are estimated using data from each subgroup separately without considering data from other subgroups in the same study. The subgroup treatment effects estimated this way may be heterogenous with high variability due to small sample sizes in some subgroups and much different from the treatment effect in the overall population. A Bayesian hierarchical model (BHM) can be used to derive more precise, and less heterogenous estimates of subgroup treatment effects that are closer to the treatment effect in the overall population. BHM assumes exchangeability in treatment effect across subgroups after adjusting for effect modifiers and other relevant covariates. In this article, we will discuss the technical details for applying one-way and multi-way BHM using summary-level statistics, and patient-level data for subgroup analysis. Four case studies based on four new drug applications are used to illustrate the application of these models in subgroup analyses for continuous, dichotomous, time-to-event, and count endpoints. | Bayesian Approaches | Journal Articles |
| The Whys, Whens, and Hows of Futility Monitoring | There are different reasons to include futility monitoring in clinical trials. We often think of futility monitoring as being planned for business decisions, to limit time and money in a trial that will likely fail its primary objective. But there are also public health and ethical reasons for conducting, or not conducting, futility monitoring in clinical trials. Important considerations in futility monitoring include maintenance of trial integrity, the methods used and their operating characteristics, and the interplay with safety monitoring. This article will discuss some of the whys, whens, and hows of futility monitoring. | Bayesian Approaches | Journal Articles |
| Application of Bayesian Borrowing Methods in Clinical Trials for Children with Type II Diabetes Mellitus | Clinical trials for children with type II diabetes mellitus (T2DM) pose challenges often due to recruitment issues. The variability in the treatment effect for pediatrics with T2DM tends to be much larger than that for adults, therefore, a larger pediatric study is needed to independently detect a similar treatment effect. If leveraging adult information to a pediatric population can be appropriately justified, and scientific rational has been given for the relevancy of the adult information, then Bayesian borrowing methods can aid in reducing the number of patients needed for a pediatric study and therefore increase feasibility and efficiency. We introduce Bayesian borrowing methods to obtain scientifically sound and conclusive results with adequate study power in anti-diabetic products development for children with T2DM. | Bayesian Approaches | Journal Articles |
| Bayesian Methods in Human Drug and Biological Products Development in CDER and CBER | The Center for Drug Evaluation and Research (CDER) and the Center for Biologics Evaluation and Research (CBER) of the U.S. Food and Drug Administration (FDA) have been leaders in protecting and promoting the U.S. public health by helping to ensure that safe and effective drugs and biological products are available in the United States for those who need them. The null hypothesis significance testing approach, along with other considerations, is typically used to demonstrate the effectiveness of a drug or biological product. The Bayesian framework presents an alternative approach to demonstrate the effectiveness of a treatment. This article discusses the Bayesian framework for drug and biological product development, highlights key settings in which Bayesian approaches may be appropriate, and provides recent examples of the use of Bayesian approaches within CDER and CBER. | Bayesian Approaches | Journal Articles |
| Why are not There More Bayesian Clinical Trials? Perceived Barriers and Educational Preferences Among Medical Researchers Involved in Drug Development | Objective and Background: The clinical trials community has been hesitant to adopt Bayesian statistical methods, which are often more flexible and efficient with more naturally interpretable results than frequentist methods. We aimed to identify self-reported barriers to implementing Bayesian methods and preferences for becoming comfortable with them. Methods: We developed a 22-question survey submitted to medical researchers (non-statisticians) from industry, academia, and regulatory agencies. Question areas included demographics, experience, comfort levels with Bayesian analyses, perceived barriers to these analyses, and preferences for increasing familiarity with Bayesian methods. | Bayesian Approaches | Journal Articles |
| Clustering Plasma Concentration-Time Curves Applications of Unsupervised Learning in Pharmacogenomics | Pharmaceutical researchers are continually searching for techniques to improve both drug development processes and patient outcomes. An area of recent interest is the potential for machine learning (ML) applications within pharmacology. One such application not yet given close study is the unsupervised clustering of plasma concentration-time curves, hereafter, pharmacokinetic (PK) curves. In this paper, we present our findings on how to cluster PK curves by their similarity. Specifically, we find clustering to be effective at identifying similar-shaped PK curves and informative for understanding patterns within each cluster of PK curves. Because PK curves are time series data objects, our approach utilizes the extensive body of research related to the clustering of time series data as a starting point. As such, we examine many dissimilarity measures between time series data objects to find those most suitable for PK curves. We identify Euclidean distance as generally most appropriate for clustering PK curves, and we further show that dynamic time warping, Fréchet, and structure-based measures of dissimilarity like correlation may produce unexpected results. As an illustration, we apply these methods in a case study with 250 PK curves used in a previous pharmacogenomic study. Our case study finds that an unsupervised ML clustering with Euclidean distance, without any subject genetic information, is able to independently validate the same conclusions as the reference pharmacogenomic results. To our knowledge, this is the first such demonstration. Further, the case study demonstrates how the clustering of PK curves may generate insights that could be difficult to perceive solely with population level summary statistics of PK metrics. | Artificial Intelligence/Machine Learning | Journal Articles |
| Multiplicity Adjustment Methods for a Three-Way Crossover Bioequivalence Study | For generic drugs, a three-way crossover bioequivalence (BE) study is often used to compare two generic (T) formulations against the common brand-name (R) formulation. Adjustment for multiplicity in equivalence testing, however, is little researched. The new ICH M13A guidance mentioned multiplicity control for equivalence but did not recommend any specific methods. In this paper, we evaluate the applicability of traditional multiplicity adjustment methods in equivalence testing. We propose three revised methods (Bonferroni, Holm, and Hochberg) which are applied on not only p-values but also the more commonly used confidence intervals in equivalence testing. We also apply the 'two-at-a-time' rule as recommended by regulatory agencies and incorporate the correlation among test statistics in simulation. All of these are advances compared to current multiplicity control methods for equivalence. Simulation shows that our proposed methods in a three-way crossover study greatly improve power and reduce needed sample size compared to conducting two two-way crossover studies, control the family-wise error rate at a desired level, and only slightly increase the required sample size compared to no alpha adjustment. Therefore, we recommend our revised Bonferroni, Holm, or Hochberg method in a three-way crossover design when assessing the BE of 2 Ts to 1 R. | Complex Innovative Trial Designs | Journal Articles |

| Perspectives on Informative Bayesian Methods in Pediatrics | Bayesian methods have been proposed as a natural fit for pediatric extrapolation, as they allow the incorporation of relevant external data to reduce the required sample size and hence trial burden for the pediatric patient population. In this paper we will discuss our experience and perspectives with these methods in pediatric trials. We will present some of the background and thinking underlying pediatric extrapolation and discuss the use of Bayesian methods within this context. We will present two recent case examples illustrating the value of a Bayesian approach in this setting and present perspectives on some of the issues that we have encountered in these and other cases. | Bayesian Approaches | Journal Articles |
| Application of Bayesian Statistics to Support Approval of Intravenous Belimumab in Children with Systemic Lupus Erythematosus in the United States | Objective: Due to the rarity of childhood-onset systemic lupus erythematosus (cSLE), the pediatric study (NCT01649765) conducted to support approval of intravenous (IV) belimumab in that population could not be designed with adequate power for efficacy to make statistical inferences based solely on the pediatric data. Bayesian analyses have been proposed to implement more flexible pediatric extrapolation approaches in similar situations. Here we discuss a post-hoc Bayesian analysis the FDA employed which borrowed information from the phase 3 IV belimumab studies in adults to supplement the efficacy information collected in the pediatric population. | Bayesian Approaches | Journal Articles |

| Example Statistical Analysis Plan for a Supplemental Bayesian Analysis: Unification of Evidence | This is an example statistical analysis plan derived from the C3TI Bayesian Statistical Analysis (BSA) Demonstration Project. The hypothetical study design is a double-blind, parallel-group, two-treatment, randomized controlled trial of drug (group B) vs. placebo (group A). The primary analysis is intent-to-treat and the outcomes are survival time (with follow-up up to three years), infection (within 90 days), and patient Performance Status (within 30 days; PS). The disease setting is a high mortality one, and infections and PS are frequently not assessable as a result. So, death is counted in both outcomes by making it the highest level of the ordinal outcome. The infection outcome thus has 3 levels (alive and infection-free for 90 days, alive and infection within 90 days, death), and PS has 6 levels. One could say that these outcomes are infection penalized for death and PS penalized for death. | Bayesian Approaches | Case Studies |
| Example Statistical Analysis Plan for Bayesian Subgroup Analysis: Sharing of Information Across Subgroups | This is an example statistical analysis plan derived from the C3TI Bayesian Statistical Analysis (BSA) Demonstration Project.

| Mitigating Limited Data Challenges to Improve Artificial Intelligence (AI) Integration in Rare Disease Drug Development | The Orphan Drug Act defines a rare disease as a condition affecting fewer than 200,000 people in the United States. However, most rare diseases are categorized as ultrarare or hyper-rare, impacting fewer than 100 individuals worldwide. Developing drugs for these conditions involves multiple challenges, such as geographically dispersed and small patient populations, limited natural history data, and poor disease characterization. Issues related to small patient numbers, scarce natural history information, and clinical heterogeneity within rare diseases can be addressed by various strategies, including using Artificial Intelligence (AI) and advanced analytical methods, leveraging detailed individual-level data, and exploring synthetic data generation to overcome the limitations of small datasets. Moreover, establishing centralized databases and promoting public–private partnerships can help build a more comprehensive repository of available data. | Artificial Intelligence / Machine Learning | Journal Articles |

| Real-World Data (RWD) as External Controls Case Study: BALVERSA (erdafitinib) | Erdafitinib is a New Molecular Entity (NME) approved for the treatment of adult patients with locally advanced or metastatic Urothelial Carcinoma (UC) that included patient-level Real-World Data (RWD) as an external control. However, the FDA review concluded that the RWD submitted were uninterpretable due to data quality and completeness issues (such as the lack of standardized approach in assessing tumor response, a small sample size, differential selection of comparison groups, and missing data) and deemed the results inconclusive. Therefore, there is no discussion of the Real-World Evidence (RWE) in the BALVERSA US Prescribing Information. These conclusions raise awareness around challenges and issues when using external control data to potentially aid in making submissions using RWD of better quality (pp. 1-27). | Real World Evidence/Data | Case Studies |
| Real-World Data (RWD) as External Controls Case Study: BRINEURA (cerliponase alfa) | Cerliponase alfa is a biologics New Molecular Entity (NME) approved for the treatment of neuronal Ceroid Lipofuscinosis type 2 (CLN2 disease) that included patient-level Real-World Data (RWD) as an external control. The FDA requested multiple comparative analyses between the clinical trial and the historical control. Despite finding some differences in patient characteristics between the two cohorts and the use of a different version of the clinician-reported outcomes (ClinROs) than the one used in the clinical trial, the BRINEURA US Prescribing Information includes the comparative analysis results on the motor domain of the CLN2 rating scale. These conclusions raise awareness around challenges and issues when using external control data to potentially aid in making submissions using RWD of better quality (pp. 9-27). | Real World Evidence/Data | Case Studies |
| Real-World Data (RWD) as External Controls Case Study: XPOVIO (selinexor) | Selinexor is a is a New Molecular Entity (NME) approved to treat patients with relapsed refractory multiple myeloma that included patient-level Real-World Data (RWD) as an external control. However, the FDA review concluded that the evidence generated from the RWD was inadequate to provide context or comparison for the overall survival observed in the single-arm trial. Therefore, there is no discussion of the Real-World Evidence (RWE) in the XPOVIO US Prescribing Information. These conclusions raise awareness around challenges and issues when using external control data to potentially aid in making submissions using RWD of better quality (pp. 83-91). | Real World Evidence/Data | Case Studies |
