A Pilot Study of LTB4 in HIV-1 Infected Adults

This is a pilot study to assess the safety and antiretroviral activity of a naturally occuring substance known as Leukotriene B4(LTB4). The aim of the study is to determine the effect of LTB4 on viral load during a period of 6 weeks, 4 weeks of active treatment and 2 additional weeks after the end of active treatment for safety follow-up. 40 patients in seven clinics in Canada will be randomized into three treatment arms, either of two doses of LTB4 or placebo. Study drug is administered intravenously once daily. LTB4 can activate and stimulate various white blood cells and by the activation release natural substances in the body and this process is an important part of the body\'s defense against infections.
