Book Description
This dissertation investigates production and inventory decisions made within clinical trial supply chains in order to reduce drug supply costs. By investigating the SEC filings of public companies, we find that drug supply costs frequently account for a significant portion of pharmaceutical companies' R & D spending. To unlock value tied up in clinical trial supply chains, three unique aspects of clinical trial supply chains are explored and associated supply chain decisions are optimized. The first unique factor that differentiates the supply chains for clinical trials is the risk of failure, meaning that the investigational drug is proven unsafe or ineffective during human testing. Upon failure, any unused inventory is essentially wasted and needs to be destroyed. We explore the effect of this failure on production planning decisions and find the planner's decision to be a balancing act between waste and destruction costs versus production inefficiency. To optimally achieve this balance, we generalize the Wagner-Whitin model to incorporate the risk of failure. A second unique aspect of clinical trials is that demand can go from being quite unpredictable to fully predictable during the course of a trial. To take advantage of this demand learning, intra-trial batches can be produced, but at the expense of scale economies. Using various learning curves, we study this balance between learning and economies of scale in a finite horizon inventory model with fixed production costs and two production options: the pre-trial batch and the intra-trial batch. We characterize the optimal policy for both production batches in regards to optimally scheduling and sizing production. Lastly, we analyze the distribution networks of global clinical trial supply chains. Unique to these networks is their temporary existence; trials are ceased after patient enrollment goals are met. To manage these networks, we present a new class of multi-echelon inventory models to make stock positioning decisions, develop algorithms to identify lower and upper bounds on the optimal objective function for this new class, and leverage those algorithms to provide insights into optimal supply chain configurations.

Book Description
Ensure your clinical trial supply chain is running smoothly with this practical guide Clinical trials are a critical part of the pharmaceutical development process. These trials cannot proceed without timely and regular receipt of the drugs being tested, which can prove a challenge for drug manufacturers who have not yet established the structures required to produce quality-controlled specimens of the drug at scale. Managing supply chains of pre-production drugs for clinical trials is therefore an essential component of drug development. Supply Chain Planning for Clinical Trials offers a practical introduction to this process for researchers and industry professionals. Beginning with the basics of clinical trial supply chain management, it proceeds step by step through all aspects of demand and supply planning for clinical trials. The result is a thorough overview that also offers practical examples of how to plan supply for clinical trials. Supply Chain Planning for Clinical Trials readers will also find: Tools for minimizing risk and expense by optimizing the relationship between supply and demand Detailed discussion of topics including quality and regulatory considerations and the business processes that support clinical trial supply chain management Spreadsheet-based models to illustrate key concepts, adaptable to the readers’ specific scenarios Supply Chain Planning for Clinical Trails is ideal for pharmaceutical industry professionals involved in clinical trial supply planning, as well as academics and researchers interested in the pharmaceutical industry and its logistics.

Book Description
Until recently, academic and practitioner research on clinical trial supply chains focused on identifying innovative models and solutions in providing comparator and study drugs to global clinical sites. Due to the expansion of outsourcing efforts by pharmaceutical organizations, newly enacted global laws and regulations, and the continued push to increase the speed at which new drugs gain market approval, a new and extremely complex global "ancillary" supply chain has emerged. This manuscript focuses on the clinical trial ancillary supply chain: a supply chain that develops the end-to-end process resulting in the distribution and quality management of medical products and devices, consumable supplies, and patient giveaways to global clinical trial sites. Based on a series of quantitative analyses, this research assesses the influence of the customer, country, and product on the overall success of the supply chain. Three factors emerged from these analyses as having a direct influence on the clinical trial ancillary supply chain; product characteristics, magnitude (components of size), and stability (components of changes in scope). Part II of this research sought to understand the success of the supply chain by evaluating the moderating effects of knowledge management, organizational culture, therapeutic area, and type of shipment. Assessments of 444 customer and server surveys yielded components of a sense of shared culture, shared communication and transparency, and feeling educated and supported. Quantitative data analysis supported that these components had a moderating influence on success during the pre-trial phase of the supply chain. These research findings provide insight into the internal and external drivers of success within the complex and emergent clinical trial supply chain - a supply chain that helps pharmaceutical organizations bring innovative therapies to market and most important, those patients in need of such therapies to improve or even save their lives.

Book Description
This book bridges the gap between practitioners of supply-chain management and pharmaceutical industry experts. It aims to help both these groups understand the different worlds they live in and how to jointly contribute to meaningful improvements in supply-chains within the globally important pharmaceutical sector. Scientific and technical staff must work closely with supply-chain practitioners and other relevant parties to help secure responsive, cost effective and risk mitigated supply chains to compete on a world stage. This should not wait until a drug has been registered, but should start as early as possible in the development process and before registration or clinical trials. The author suggests that CMC (chemistry manufacturing controls) drug development must reset the line of sight – from supply of drug to the clinic and gaining a registration, to the building of a patient value stream. Capable processes and suppliers, streamlined logistics, flexible plant and equipment, shorter cycle times, effective flow of information and reduced waste. All these factors can and should be addressed at the CMC development stage.

Book Description
As a result of slow patient recruitment and high patient costs in the United States, clinical trials are increasingly going global. While recruitment efforts benefit from a larger global footprint, the supply chain has to work harder at getting the right drug supply, to the right place, at the right time. Certain clinical trial supply chains, especially those supplying biologics, have a combination of unique attributes that have yet to be addressed by existing supply chain models. These attributes include a fixed patient horizon, an inflexible supply process, a unique set of service-level requirements, and an inability to transfer drug supplies among testing sites. In this paper, we provide a new class of multi-echelon inventory models to address these unique aspects. The resulting mathematical program is a nonlinear integer programming problem with chance constraints. Despite this complexity, we develop a solution method that transforms the original formulation into a linear integer equivalent. By analyzing special cases and through numerical study of both real-life and simulated examples, we develop novel insights into inventory positioning and the cost drivers in clinical trial supply chains.

Book Description
Over the past several decades, supply chain disruptions have repeatedly plagued the U.S. health care system, costing health care systems millions of dollars per year, threatening the clinical research enterprise, and most importantly, imperiling the health and lives of patients. The Committee on Security of America's Medical Supply Chain, convened by the National Academies of Sciences, Engineering, and Medicine, was charged with addressing this important issue by examining the root causes of medical product shortages and identifying ways to enhance their resilience - both in so-called normal times and during public health emergencies. Building Resilience into the Nation's Medical Product Supply Chains outlines the committee's seven recommendations and presents a framework of protection comprising awareness, mitigation, preparedness, and response measures.

Book Description
Remote clinical trials present the new approach of revolutionizing traditional clinical trials in order to decrease costs, accelerate the processes and improve the experience for participants and trial's staff. The Covid-19 pandemic has significantly encouraged the implementation of remote clinical trials, since it became harder to reach participants and patients. The Tufts Medical Center aims to adopt remote clinical trial practices for their future clinical trials. The future trials include (1) a phase 2b a clinical trial testing the effectiveness of niclosamide in the shortening the Covid-19 contagious period in children and adolescents and (2) a data collection trial with participants suffering from Long Covid symptoms. Although clinical trials can have different parameters and processes, this thesis suggests a general framework that can guide Tufts Medical center in their planning of the future remote trials including the design of the trial, the participant's recruiting, the trial's supplies' inventory management and the data collection during and at the end of the trial. The thesis also includes limitations and points of failure of the generalized framework.

Book Description
Despite significant achievements, the discipline of supply chain management is still unable to satisfactorily handle many practical real-world challenges. The authors of Networks Against Time claim that a unified supply chain network analytics framework is needed which should be able to handle optimization and competitive behavior while also maintain relevance to many industrial sectors in which perishable products are prominent, from healthcare to food and from fashion apparel to technology. This Brief provides a wide range of critical supply chain problems which are modeled as generalized networks. Guidelines are provided to determine the arc multipliers that capture perish ability of the product whether food, radioisotopes, or even highly perishable blood in healthcare over space and time. Through case studies the authors portray the application of the models and algorithms to real-world sectors which illustrate the power of the framework in practice. The models and algorithms are fully described along with the input and output data in the case studies. This level of transparency is useful pedagogically as well as for future research and for applications in practice. Researchers and practitioners in mathematics, in operations research and management science, operations management, as well as in economics and computer science will find this book useful to gain a broader appreciation of the richness of network supply chain structures, processes, and applications. This book can also be used by advanced undergraduate students and graduate students in the disciplines noted above to familiarize themselves with methodologies and supply chain network models and applications.
