Design and Interpretation of Stability Studies for Product Development
Developing a Line-of-Sight for Product Stability – Forced Stress Testing Through ICH Stability Requirements
Robert A. Reed, Ph.D., Vice President, CMC & Technical Operations, Celsion Corp.
Best practices have been established for forced stressed degradation studies that allow an accurate prediction of chemical “potential” for a reaction to occur. Furthermore, in-silico prediction software is emerging as a useful tool to fully consider likely reactive pathways that may play an important role in the drug stability. This talk will attempt to provide a high level introduction for best practices to establish degradation potential for a drug substance and some of the pit falls that one may encounter in bridging to ICH stability studies. Case examples will be presented to highlight some of the presented concepts. Overall, the goal is to develop confidence in the predictability and interpretation of early drug development product stability studies for the commercial market.
Controlling Reactive Components in Polymeric Pharmaceutical Excipients for Improving the Stability of APIs
Shaukat Ali, Ph.D., Technical Sales Manager, BASF Corp.
Excipients play important roles in the stability of APIs in the drug development. The key attributes leading to instability of a drug could vary from the nature of an API and the excipients used in the formulation dosages. Most importantly, the drugs sensitive to peroxides may have direct implication on the stability of product development. This presentation will cover the understanding of underlying mechanisms for oxidation of drugs and identifying the appropriate measures or safe guards to improve the stability of an API from the excipients’ perspectives.
Integrating Mechanistic Drug Degradation Pathways and Mathematical Modeling in Stability Assessment and Prediction
Ajit S. Narang, Ph.D., Sr. Research Investigator, Drug Product Science & Technology, Bristol-Myers Squibb, Co.
Predicting the kinetics of drug degradation on storage stability can be challenging. Integrating mechanistic understanding of the drug degradation pathway along with kinetic mathematical modeling of the degradation rate can not only help predict drug product stability, but also quantify the effect of underlying variables and identify mitigation strategies. In this talk, case studies would be presented where mechanistic understanding was combined with mathematical modeling to understand and mitigate stability risks during the manufacturing and stability of an oral solid dosage form.

Roadmap for Outsourcing of Preclinical Imaging
This complimentary workshop is designed as a one stop shop event for individuals from industry to get a sense of the preclinical imaging CRO landscape. With the recent trend of outsourcing more and more preclinical imaging to CROs, pharma companies are often missing the critical information of imaging and scientific capacities of various imaging CROs.
Participants include: Maccine, InviCRO, Molecular Imaging, Inc.
Processing, Analyzing, Reporting and Archiving Images in Drug Discovery and Development
Matthew Silva, Ph.D., Director, Imaging Research, inviCRO, LLC
Improvements in pre-clinical imaging instrumentation over the past decade enabled an increase in novel, translational in vivo imaging applications. While molecular probes and image acquisition protocols have translated well, however, there has not been an analogous translation of image processing protocols. Using case studies, this talk will focus on improving the reproducibility and throughput of pre-clinical image processing protocols across a broad spectrum of applications.
Application of Imaging Technologies to Drug Discovery and Development Studies in Nonhuman Primates
Mahesh Mistry, Ph.D., Executive Director, Preclinical Development, Maccine Pte Ltd
The wider application of imaging technologies to preclinical drug efficacy and safety research has the potential to greatly improve prediction of clinical success; especially when applied to non-human primate studies. Herein we describe how PET, CT and MRI imaging modalities are being applied to nonhuman primate efficacy, ADME/PK and safety studies.

Dinner Short Courses | 6:00 pm—9:00 pm*
»Advances in Imaging Quantitation
Scientific Advisor and Course Moderator
James Gee, PhD, Professor and Director, Penn Image and Computing Science Laboratory, University of Pennsylvania
The short course includes three lectures:
I. Image Segmentation I
Instructor: Paul Yushkevich, Ph.D., Assistant Professor, Department of Radiology, University of Pennsylvania
Overview In a multitude of image analysis applications, segmentation plays a crucial supporting role. It is a necessary first step for measuring the volume, thickness, and shape of anatomical structures. It is equally necessary for measuring physiological properties of tissues and organs. After decades of research, fully automatic segmentation remains elusive for many applications. Furthermore, some of the most effective automatic segmentation methods are highly application-specific, require extensive training data in the form of expert manual segmentations of example images, and thus very difficult for end-users to implement. Despite these challenges, more and more general-purpose software tools for image segmentation are becoming available, making accurate automatic segmentation more broadly available to imaging researchers. In this lecture, we will discuss effective automatic, semi-automatic and manual segmentation approaches that can be practically implemented using freely available software.
- A decision tree for segmentation approaches and software;
- Manual segmentation: tools, protocols, reliability analysis;
- Semi-automatic segmentation with active contours using ITK-SNAP;
- Atlas-based segmentation and multi-atlas label fusion using ANTS;
- Automatic brain segmentation using complex, multi-algorithmic packages FSL and FreeSurfer;
- Validation of automatic segmentation.
II. Image Registration
Instructor: Brian Avants, Ph.D., Postdoctoral Researcher., Department of Radiology, University of Pennsylvania
Overview Biomedical image registration maps a known coordinate system onto unstructured data. This tool is useful in several application areas: medical diagnostics, planning and following radiation therapy, tracking pharmaceutical efficacy during longitudinal studies and in brain mapping. Tremendous algorithmic progress over the last 10 years extends the types of problems that may be studied successfully with this powerful analysis technology. Furthermore, several advanced image registration tools are now freely available to the public. We will introduce basic concepts in image registration and illustrate its application within application areas at the cutting-edge of translational biomedical science.
- Build a population-specific template coordinate system;
- Map this coordinate system to new subjects or within a subject over time;
- Evaluate the success of longitudinal and cross-sectional transformations;
- Collect population information within the template coordinate system;
- Do a basic statistical analysis in a template space.
III. Image Segmentation II
Instructor: Kevin Zhou, Ph.D., Research Group Head, Siemens Corporate Research
Overview Efficient, effective, and fully automatic segmentation of anatomical structures is highly desired for many high-throughput 3D imaging applications but still remains elusive. Recently, context learning methods offer promising solutions. They are based on machine learning principles, such as classification and regression, to learn the statistical relationships between the anatomical structures of interest and 3D images from an annotated database consisting of both images and their corresponding annotations. In this lecture, we will present approaches that leverage anatomical context embedded in the medical images and illustrate the efficiency and effectiveness of these approaches using real examples.
- Challenges and opportunities for efficient and effective image segmentation;
- Anatomical context and its categorization;
- Context learning: Classification vs Regression;
- Context integration;
- Rapid multi-organ segmentation from human and animal images.
