Actin exposure upon tissue injury is a targetable wound site-specific protein marker.

Background: Identification of wound-specific markers would represent an important step toward damaged tissue detection and targeted delivery of biologically important materials to injured sites. Such delivery could minimize the amount of therapeutic materials that must be administered and limit potential collateral damage on nearby normal tissues. Yet, biological markers that are specific for injured tissue sites remain elusive.

Benchmarking safety pharmacology regulatory packages and best practice.

Introduction: The objectives of this survey were to obtain a global information update regarding current industry perspectives that describe Safety Pharmacology programs as they relate to the ICH S7A and S7B regulatory guidelines but also to obtain a broader perspective of other practises practices in the field currently used by companies. Preliminary findings were presented at the 7th Annual Meeting of the Safety Pharmacology Society (SPS) (Edinburgh, Scotland, Sept 19-21, 2007).

Methods: The survey was distributed by the SPS to 125 pharmaceutical companies.

International Life Sciences Institute (Health and Environmental Sciences Institute, HESI) initiative on moving towards better predictors of drug-induced torsades de pointes.

Knowledge of the cardiac safety of emerging new drugs is an important aspect of assuring the expeditious advancement of the best candidates targeted at unmet medical needs while also assuring the safety of clinical trial subjects or patients. Present methodologies for assessing drug-induced torsades de pointes (TdP) are woefully inadequate in terms of their specificity to select pharmaceutical agents, which are human arrhythmia toxicants. Thus, the critical challenge in the pharmaceutical industry today is to identify experimental models, composite strategies, or biomarkers of cardiac risk that can distinguish a drug, which prolongs cardiac ventricular repolarization, but is not proarrhythmic, from one that prolongs the QT interval and leads to TdP.
