HIV Clinical Pharmacology and ImplementationResearch in YRG CARE, India

S. Saravanan, PhD

4th Annual Workshop on

• 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.

• 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.

Background

• 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.

• 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.

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.

• Completed Instrumentation & Application training

• Process of NIH Fogarty Application: UB AIDS Clinical Trials Group PSL & YRG CARE Planning Grant for Fogarty HIV Research Training Program for Low- and Middle- Income Country Institutions (D71)

• 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.

Anticipated contribution of establishing Clinical Pharmacology at YRG CARE:
