Pharmacokinetics & Investigational Chemotherapy
Beth McLendon-Arvik, PharmD
Director, Investigational Drug Services
The primary purpose of the Pharmacokinetics & Investigational Chemotherapy Shared Resource is to provide a broad spectrum of pharmacological and pharmaceutical services essential to the conduct of preclinical and clinical research in oncology, drug discovery, drug evaluation, and related areas by members of the Duke Cancer Institute (DCI). It is composed of two services: the Investigational Chemotherapy Service and the Pharmacokinetics/Pharmacodynamics (PK/PD) service.
The Investigational Chemotherapy Service (ICS) is available to all DCI investigators for the purpose of preparing investigational drug products, maintaining drug accountability records and investigational drug inventories according to FDA and Cancer Therapy Evaluation Program (CTEP) guidelines. In addition, this service provides design consultation, professional staff education, and implementation services for clinical research studies. The ICS is managed by the Department of Pharmacy under the leadership of Paul Bush, PharmD, Chief Pharmacy Officer. Beth McLendon-Arvik, PharmD is the Manager of Duke University Hospital Investigational Drug Services and the ICS. The ICS is staffed by a clinical pharmacist, a clinical research coordinator and clinical research specialist. The ICS utilizes a software program, Vestigo, to automate and streamline many aspects of its daily workflow.
The PK/PD Core is available to all DCI investigators for pharmacokinetics, pharmacodynamics, and small molecule research in general providing the following services: study feasibility assessment and design of Phase I/II clinical studies and comprehensive pre-preclinical PK/PD studies for candidate drugs, analytical assay development and analysis of drugs and metabolites in bodily fluids and tissues, PK/PD modeling, data interpretation, publishing, and help with funding applications. The facility is managed by DCI under the leadership of Ivan Spasojevic, PhD, an Assistant Professor in the Department of Medicine. It is staffed by research analysts and is equipped with state-of-the-art analytical and computational equipment.
