Background: Elvucitabine (ACH123,446)(ELV) is a cytosine NRTI analog with potent in-vitro activity against wild type HIV-1 virus Methods: A Phase II, prospective, randomized, blinded, comparison of ELV 10 mg versus lamivudine (LAM) 300 mg both administered daily in combination with efavirenz 600 mg and tenofovir DF 300 mg in HIV-1-infected, treatment-naïve subjects. Results: 77 subjects were randomized with 76 subjects receiving at least one dose of study medication. Seventy-four subjects (37 per treatment group) had both baseline and post-baseline HIV-1 RNA measurements.Fifty-five subjects completed 48 weeks of treatment. The reasons for not completing 48 weeks were: physician decision (n=5), voluntary withdrawal (n=5), adverse event (n=4), lost to follow-up (n=4), sponsor decision (n=3), and death (n=1). Baseline characteristics were similar between treatment groups. The proportion of subjects at week 48 with HIV-1 levels of less than 50 copies/mL in the ITT patient population was : 65% in the ELV and 78% in the LAM treatment group (95% CI for the difference = -0.34, 0.07)( as-treated patient population was 96% for ELV and 97% for LAM). At week 48, the ELV treatment group experienced a mean (SD) change in percent CD4 of +9.9 (6.3) versus +9.1 (7.2) with LAM. The incidence, frequency, type, and severity of adverse events were similar between treatment groups. Conclusions: ELV administered in combination with tenofovir and efavirenz demonstrates substantial anti-viral activity.

Dushyantha T. Jayaweera MD, MRCOG (UK) FACP
I am an Associate Professor in Medicine, at the Division of Infectious Diseases, in the Department of Medicine at University of Miami School of Medicine. I am investigator for several ongoing clinical studies evaluating the safety and efficacy of various antiviral treatment regimens for HIV and Hepatitis/HIV coinfection.
After graduating from University of Sri Lanka in Colombo, I completed training in OBGYN in Sri Lanka and in England. Following this training I changed my specialty to medicine and completed a residency program in internal medicine in Chicago (Loyola/Hines VA program) and returned to England for further training in HIV and Sexually Transmitted Diseases. In 1992 I joined the University of Miami as an Assistant Professor in Medicine and have been working at the University since then. I was promoted to Associate Professor in 1997. I have been the director for the HIV fellowship program for the last 7 years.
I am a fellow in the American College of Physicians and a Member of the Royal College of OBGYN. I am a member of the ethics committee at the university of Miami and have also worked as ad hoc member in NIH review panels. I have been a visiting professor to many countries which include, Si Lanka, Nigeria, Jamaica and China. I have published many articles in peer reviewed journals and most of this work has been in HIV and hepatitis B.
