When you think of a pathologist, you may picture a scientist peering through a microscope, viewing slides and making notes about a disease state, then moving on to the next sample. Indeed, the classic role of many contract pathologists is to evaluate large numbers of tissue slides and author pathology reports. However at Covance, the Lead Optimization Pathology group plays a much greater role in drug development.
The Lead Optimization Pathology group offers Project Pathologists—a staff pathologist with therapeutic area expertise who is assigned to a project and intimately involved in supporting the early drug development in both efficacy and non-GLP toxicity studies. As ACVP board certified veterinary pathologists with Ph.D. degrees and past experience working in large pharmaceutical companies, the staff can offer in-depth pathology support for both small and big clients.

Cardiovascular safety remains a leading cause of drug attrition during preclinical and clinical development, accounting for discontinuation of approximately one third of marketed drugs.
These liabilities, which pertain to both cardiovascular- and non-cardiovascular-targeted drugs, can be identified during early development by addressing cardiovascular safety endpoints prior to the selection of a drug candidate, a process known as ‘frontloading’. Although not mandated by the key regulatory guidance for safety pharmacology (ICH S7A; US FDA, 2001), an increasing number of companies choose to conduct early non-GLP cardiovascular safety studies in support of decisions on the progression of their compounds.

Lead optimization (LO) is one of the most expensive and time-consuming stages of the drug development process due to the number of programs running simultaneously and the number of molecules within each of those programs. Covance’s Lead Optimization Pharmacology & Toxicology services are designed to help you select the best molecule for candidate selection and further development. Our ability to integrate service lines, such as pharmacology, biomarkers, imaging and safety, and thoughtfully add endpoints to studies, maximizes the number of questions being answered in each study leading to improved probability of technical success. The following video gives an overview of our Lead Optimization Pharmacology & Toxicology services and the benefits of choosing Covance as your LO partner.
Identifying clinically useful compounds and developing a novel drug treatment to improve human health has many rewards. But with increasing press about the growing abuse of prescription medications and potentials for physiological or physical dependence, regulatory agencies around the world have taken note.
Called abuse liability testing, this stage of drug development was first officially recognized in 1970 with the U.S. Controlled Substances Act. Since then, many iterations and guidelines have been developed to determine a compound’s potential for abuse.
Abuse liability studies are very important because they are required by the regulatory agencies in U.S., Europe, and even Asia for setting the scheduling of new chemical entities that come into the marketplace. Continue reading
Successful drug development is increasingly dependent on a robust “fail fast” strategy that includes incorporation of safety / toxicology endpoints into lead optimization pharmacology studies. This early marriage of pharmacology and toxicology will provide insight into the margin of safety that is critical for advancing the molecule, the design of the GLP studies and the clinical plan. Biopharmaceutical companies that employ a “fail fast” strategy can make safety decisions from the integration of toxicology into pharmacology studies, which markedly reduces lead optimization cycle times and overall spend during this phase.
