  1. 4th Annual Workshop on HIV Clinical Pharmacology and Implementation Research in YRG CARE, India S. Saravanan, PhD

  2. Background • YR Gaitonde Centre for AIDS Research and Education (YRGCARE) in Chennai, India is a non-profit medical and research institution. Established in 1993, the activities are organized around four core areas - Education, Care & Support, Research and Training. YRGCARE Medical Center is a 20- bed clinical facility with an intensive care unit, an outpatient unit, counseling and nutritional services, a subsidized pharmacy with adherence program. YRGCARE has a well developed Hospital Management System (HMS) database which integrates the clinic, laboratory and pharmacy. The Natural History Database (NHD), a subset of the HMS, provides valuable insight about the progression of HIV disease in India.

  3. YRG CARE Infectious Diseases Laboratory is quality assured by the College of American Pathologists (USA) and UK-NEQAS (UK), quality controlled by the Johns Hopkins University, USA and Virology Quality Assurance Program, Rush, USA • YRG CARE (Site ID: 11701 & Lab ID: 316) is one of the international multi site of NIH multi-centric clinical trials sponsored by DAIDS through HPTN and ACTG programs from the year 2000. • YRG CARE performs all the protocol assays, which include HIV-RNA & DNA PCR, CD4, blood chemistries, CBC, infectious diseases serology, clinical pathology and diagnosis of opportunistic infections including TB.

  4. Affiliated to the University of Madras, Chennai for conducting Ph.D. degree program in Medical Microbiology. • Biochemistry, Clinical Pathology, HIV Genotyping Lab, Hematology & Immunology, Microbiology, Serology, Virology & Molecular biology • Accredited by National Accreditation Board for Testing and Calibration Laboratories (NABL, New Delhi) and the NABL accreditation is assessed in accordance with ISO 15189:2007 standards for medical laboratories. • YRG CARE Laboratory is the very first HIV specialty laboratory got accredited by the NABL in India.

  5. HIV Clinical Pharmacology and Implementation • Objectives • Development and validation of analytical procedures for the • quantification of antiretroviral agents. • Participation in the DAIDS HIV Clinical Pharmacology Quality • Assurance (CPQA) program. • Implementation of DAIDS mandated requirements eventually • to become Pharmacology Specialty Laboratory to support the • scientific agenda of the DAIDS.

  7. Waters Alliance Training at YRG • Orientation about Alliance e2695 • 2998/PDA • Preventive maintenance • Priming the Solvent Management System • Dry Priming & Wet Priming • Priming the Needle-Wash Pump • Priming the Plunger Seal-Wash Pump • Purging the Injector

  8. Priming • Fixing column • Conditioning the Column

  9. Sample preparation • Mobile phase preparation • Loading Carousels • Empower software & utility

  10. 1. Configure system 2. Creating instrument method 3. Creating method set 4. Processing method 5. Reporting format

  11. NVP estimation using Xanthine as IS • Reverse Phase HPLC • Liquid Extraction – Ethyl Acetate • Mobile Phase: KH2PO4:ACN(90:10)

  12. Calibration Curve

  13. Peak Summary Peak Summary Report Retention Time: 6.75 mins for Xanthine; 8.02 mins for NVP

  14. Estimation of Stavudine and Lamivudine using Didanosine as the Internal Standard Solid Phase Extraction Method Oasis HLB cartridges 3TC : 8.30 mins DDI(IS): 10.23 mins D4T : 11.98 mins

  15. Current Status • Alliance e2695 /2998 PDA – Installed • Completed Instrumentation & Application training • Process of NIH Fogarty Application: • UB AIDS Clinical Trials Group PSL & YRG CARE • PlanningGrant for Fogarty HIV Research Training • Program for Low- and Middle- Income Country • Institutions (D71)

  16. Anticipated contribution of establishing Clinical Pharmacology at YRG CARE: • Upon the completion of technology transfer from UB, the assays will be standardized and will complete the CPQA panels. Eventually the PSL would support the scientific agenda of the ACTG/HPTN. • The established PSL would carry out protocol-required pharmacologic assays - analysis of PK/PD data from both primary protocols and sub-studies. • Develop concept proposal and integrate pharmacologic research questions with the ACTG/HPTN scientific agenda.

  17. Thanks
