Sunday March 16, 2008 8:15 AM CE Session - AM03Session Title: Stem Cells and Their Multipotential Uses and Potential DangersPO/PL Chairperson: David LawrencePO/PL Co-Chair: Marc PallardyLocation: Room 605 (Convention Center)

Stem cells can theoretically divide without limit to replenish cells and each daughter cell has the potential to remain a stem cell or develop into a fully functional differentiated cell. Therefore, stem cells have the potential to develop into many cell types that could benefit the health status of many individuals but the types of cells that could differentiate from stem cells must be considered in that certain growth and differentiation factors could give rise to conditions that could be harmful including development of a cancer stem cell. Additionally, environmental factors can skew the developmental patterns of stem cells leading to harmful deficiencies or expansions of certain types of progenitors. This course is designed as a basic level course to provide an overview of the field of stem cell biology, touch upon the differences of adult versus embryonic stem cells and provide a foundation for understanding the implications of the use of stem cells in toxicological research. Presentations will cover in vitro and in vivo proliferation and differentiation of stem cells and the influences of toxicants on these processes. Quantification of normal and aberrant immunophenotypic changes with development, mechanisms that influence proliferation, differentiation, and functional changes, and in vivo control of progenitors in their developmental niche will be discussed. The effect of environmental toxicants on a single molecular pathway controlling cell signaling and development of the CNS will be presented. Finally, the challenges in pharmacologically regulated cell therapy including the ability to regulate the fate of engineered cells will be deliberated.

Wednesday March 19, 2008 4:30 PM Informational SessionSession Title: Implementation of the ICH S8 Immunotoxicity Testing GuidelinePO/PL Chairperson: Thomas KawabataPO/PL Co-Chair: Pramila SinghLocation: Room 615 (Convention Center)

The ICH S8 Guideline, “Immunotoxicity Studies for Human Pharmaceuticals” provides recommendations for nonclinical safety testing of low molecular weight drugs for potential to induce harmful effects via suppression of the immune system. It applies to new drugs; existing drugs in which intended indication or label changes may result in unaddressed toxicological issues; and drugs in which signs of immunosuppression arise during clinical trials or following market approval. Preparation of the S8 guidance document progressed through the combined efforts of pharmaceutical industry representatives (PhRMA, JPMA, EFPIA) and members from tripartite government regulatory agencies (FDA, MHLW, CHMP) who recognized the need for globally harmonized regulatory guidance on immunotoxicological testing in drug development. Over the years leading up to the adoption of the S8 Guideline by regional regulatory agencies (2005-2006), there was significant debate and even some confusion over the compulsory versus voluntary nature of the testing recommendations and on how to apply the guidance in concert with pharmaceutical industry objectives. The purpose of this informational seminar is to provide a forum for the discussion of the practical implementation of the S8 Guideline including industry case examples and questions that remain unanswered. A panel consisting of members of the ICH S8 Expert Working Group responsible for creating the S8 Guideline and representing the U.S., Europe, and Japan will be available to answer questions from the audience. This session is intended to be an interactive forum with the expert panel, audience, and selected speakers from industry who have comments or questions on the scope and application of the S8 Guideline in current industry practice. The session will begin with a brief introduction followed by an overview of the development of the S8 Guideline and the rationale for the recommendations made. This will be followed by two individual oral presentations by industry professionals with key opinions to consider about the practical application of the Guideline, an open question and answer session, and concluding thoughts.4:30 - 4:35 PM#2042a.
