8:30 Chairperson’s RemarksOrn Almarsson, Ph.D., Vice President of Pharmaceutical Chemistry, Alkermes Inc.
8:35 Supercritical Fluid Chromatography (SFC) as an Isolation Tool for By-Product and Impurity IdentificationTodd Zelesky, Scientist, Development Analytical Department, Pfizer Inc.As a drug moves successfully through the development stages of the pipeline it becomes increasingly important to identify drug related impurities. By-product structural information can be instrumental to the process chemists in moving forward with key reaction optimization decisions. Supercritical Fluid Chromatography (SFC) is an isolation and purification tool that allows for targeted impurities to be isolated quickly. SFC has many notable advantages over HPLC for the isolation of reaction impurities, including cost effectiveness and speed.
9:05 Case Studies of Analytical Challenges in API Process Research & DevelopmentYong Chen, Ph.D., Research Investigator, Process Analytical Chemistry, Process R&D, Global Pharmaceutical R&D, Abbott LaboratoriesAnalytical strategies for the investigation and control of process-related impurities during the development of scaled-up API processes will be discussed. Emphasis will be focused on orthogonal method development and innovative chromatographic approaches coupled with modern detection technologies. Case studies will demonstrate efficient approaches toward understanding and tracking the origin, fate, and rejection of critical impurities in the entire scale-up processes.
9:40 Networking Coffee Break, Poster and Exhibit Viewing
10:15 Pharmaceutical Co-Crystals: History and Relevance to Drug DevelopmentOrn Almarsson, Ph.D., Vice President of Pharmaceutical Chemistry, Alkermes Inc.The aim of this presentation will be to provide perspective on the recent development of the field of pharmaceutical co-crystals. Prior to 2002, this field was dormant, with a few examples of pharmaceutically relevant co-crystals scattered in the literature. A surge of interest ensued in 2002, spurred in part by productivity concerns and demand for innovation in pharmaceutical R&D. Areas of impact of pharmaceutical co-crystal technology will be discussed, including tailoring materials for improved product performance, processing and separations.

2:15 PAT for Product Quality and Batch-to-Batch Consistency in API CrystallizationReginald Tan, Ph.D., Principal Scientist and Program Manager, Crystallization and Particle Science Group, Institute of Chemical and Engineering Sciences-SingaporeCrystallization is the most important unit operation for the separation and purification of chemicals in the pharmaceutical industries. Crystallization processes in pharmaceutical active ingredient manufacturing have been traditionally a recipe-based operations, offering little scope for dynamic process control and improvement. With the change in regulatory climate from Quality-by-Testing (QbT) to Quality-by-Design (QbD) and with the advent of the Process Analytical Technology (PAT) initiative, it is timely to examine the impact of such quality-based emphasis on crystallization control. In this presentation, we will discuss the use of PAT for control of crystallization. Case studies will be presented to demonstrate the new control strategies employing ATR-FTIR and FBRM in achieving the desired particle size distribution and batch-to-batch consistency in cooling and anti-solvent crystallization processes.
2:45 Networking Refreshment Break, Poster and Exhibit Viewing
3:30 Controlling Crystal Properties for FormulationHelen P. Jones, Ph.D., Crystallization Specialist, AstraZeneca Process EngineeringThe aim of crystallization process design is to develop robust processes to deliver crystalline material with consistent particle properties for formulation. Here a methodology for design of robust crystallization processes will be described. The effects of seeding, temperature cycling and pharmaceutically acceptable additives on particle size and morphology will be considered.
4:00 Crystal Engineering of Pharmaceutical Co-CrystalsMichael Zawarotco, Ph.D., Professor and Chair, Chemistry Department, University of South FloridaThe range of crystal forms available for a given API has traditionally been limited to salts, polymorphs and hydrates/solvates. The field of crystal engineering focuses upon self-assembly of existing molecules or ions and it has evolved in such a manner that a wide range of new compounds can be generated using rational design strategies. APIs are particularly amenable to crystal engineering studies as exemplified by an emerging class of crystal forms that have been termed pharmaceutical co-crystals, i.e. co-crystals involving an API and a stoichiometric amount of a pharmaceutically acceptable co-crystal former. This presentation will address the history, design, preparation and properties of pharmaceutical co-crystals.
