The broad, long-term objectives of the Clinical Pharmacology and Analytical Chemistry Core are to provide a full spectrum of pharmacologic support for HIV/AIDS-related research of the UNC CFAR. Members of the Clinical Pharmacology and Analytical Chemistry Core proactively engage UNC CFAR investigators to identify and deliver services essential for highly productive design, management, analysis and publication of HIV/AIDS research. The Core contributes to the framing of hypotheses, development of study designs, preparation of grant applications, selection or creation of best analytical chemistry and pharmacometric methods, facilitating multidisciplinary and translational approaches to the design of and conduct of clinical studies, and delivery of preclinical or clinical analyses.
Investigators new to HIV/AIDS research receive highest priority for Core services. Strong institutional support from the School of Pharmacy allows the Core to take full advantage of existing infrastructure, resources and contacts with faculty renowned for their expertise in specialized fields of pharmacology. The Core supports drug quantification in a variety of matrices with 6 AB Sciex 5000 Triple Quadrupole Mass connected to Shimadzu HPLC systems running on Analyst software and an infrared matrix assisted laser desorption electrospray ionization (IR-MALDESI) imaging source coupled to a Thermo QExactive/H-ESI II Bundle mass spectrometer similar to that housed in the inventor of this technology’s laboratory (David Muddiman, North Carolina State University).
CPAC Laboratory Aims
Aim 1: Provide access to a diverse array of cost-effective services for pharmacology research.
Aim 2: Stimulate, develop and disseminate new innovative technologies and services to enhance HIV/AIDS research.
Aim 3: Support priority CFAR initiatives and goals and collaborative research.
Aim 4: Develop and promote synergistic relationships between the UNC CFAR Cores and Working Groups, and other CFAR.
Aim 5: Provide clinical pharmacology, pharmacometric, and analytical chemistry training, mentoring, and education, and outreach.
Aim 6: Engage in evaluation and strategic planning.
CPAC Validates Novel Assay to Measure Antiretrovirals in Dried Blood Spot for Adherence Monitoring
The Clinical Pharmacology Core has recently developed and validated a sensitive, multiplex LC-MS/MS assay to measure the intracellular metabolites of the 3 most commonly prescribed NRTIs (tenofovir, emtricitabine, and lamivudine) in dried blood spots collected from patients on therapy. This assay allows investigators to monitor adherence in clinical trials with the convenience of dried blood spot sampling, storage and shipping. The addition of lamivudine, which is generically available, opens up opportunity for international investigations. Our methods and findings are in press in the Journal of Pharmaceutical and Biomedical Analysis (Schauer et al. Validation of an LC-MS/MS Assay to Simultaneously Monitor the Intracellular Active Metabolites of Tenofovir, Emtricitabine, and Lamivudine in Dried Blood Spots. JPBA. In press).
Acknowledgment, Recognition and Future Service
All work provided by the UNC CFAR Clinical Pharmacology and Analytical Chemistry Core which is included in a publication should acknowledge the contribution of the Core. Proper acknowledgment enables us to obtain financial and other support so that we can continue to provide essential services in the best ways possible. It would be appreciated if you sent a copy of the accepted manuscript, published paper, or title of grant application to firstname.lastname@example.org. This will allow us to demonstrate our impact to the research community.

Kashuba received her Pharm.D. from the State University of New York at Buffalo and completed postdoctoral pharmacology training at the Clinical Pharmacology Research Center at Bassett Healthcare in Cooperstown, New York.
Kashuba joined the UNC-Chapel Hill faculty in 1997. She was named the John and Deborah McNeill, Jr. Distinguished Professor in 2013 and appointed chair of the Division of Pharmacotherapy and Experimental Therapeutics in 2015. She serves as director of the UNC Center for AIDS Research Clinical Pharmacology and Analytical Chemistry Core, and director of the Analytical Chemistry Laboratory for the Verne S. Caviness General Clinical Research Center. She is a diplomat of the American Board of Clinical Pharmacology. Research Kashuba’s research interests focus on the clinical pharmacology of antiretroviral agents used in the treatment of HIV infection. Specifically, she is investigating the role of antiretroviral therapy in preventing the transmission of HIV, determining optimal dosing and drug combinations for the treatment of HIV infection, understanding and predicting drug-drug and drug-cytokine interactions and adverse effects, and role of sex and ethnicity in drug disposition.

3. Tier 3 – Validated (clinical studies for FDA submission, TDM, PT, method fully validated according to FDA guidelines)
The samples the CPAC laboratory analyzes come in a variety of human and animal matrices, including, but not limited to:
• peripheral blood mononuclear cells (PBMCs)
• red blood cells (RBCs)
• cervical tissue*
• rectal tissue*
• vaginal tissue*
• adipose tissue*
• rectal fluid
• cerebrospinal fluid (CSF)
• breast milk
• cervicovaginal fluid (CVF)
• dried blood spots (DBS)
Analysis costs start at $80 per sample. *Tissue analysis costs start at $100 per sample. If weights of tissues samples are not provided by the investigator, tissues can be weighed in the CPAC lab for an additional fee. QA/QC charges are calculated based on the service level (Tier 1-3) and added to the base sample analysis costs. Contact Mlcottre@email.unc.edu for budgeting inquiries.
If any facility personnel makes a substantial intellectual and/or experimental contribution to a publication they deserve recognition just as any other co-author. This is essential for the professional development of our staff. We recommend scientists follow the “ABRF Recommended Guidelines for Authorship on Manuscripts.” Services provided on a fee-for-service basis does not diminish the importance of our scientists impacting your research.
