Glaxo's Ziagen, Combivir Drug Combination Effective In Study
Dow Jones Newswires
SAN DIEGO -- A small study showed Glaxo Wellcome PLC's (GLX) investigational anti-HIV drug Ziagen combined with Combivir appears effective in reducing viral load and increasing CD4 cell counts in patients who previously received certain treatments.
In a press release Monday, Glaxo Wellcome said 28 of 39 patients, or 72%, had undetectable virus after undergoing 16 weeks of treatment with Ziagen and Combivir.
The patients had previously received treatment only with monotherapy or combinations of certain nucleoside analogue drugs, and in a few cases with certain nonnucleoside inhibitors.
The median viral load of the 87 patients enrolled in the study was initially 1,259 and median CD4 cell count was 506.
After 16 weeks of treatment with Ziagen and Combivir, 72% of patients had less than 400 viral copies and 54% had less than 50 copies, Glaxo Wellcome said.
Glaxo Wellcome said median CD4 cell counts among the patients rose to 536.
The preliminary data provides promise that the combination of Combivir and Ziagen may effectively supress HIV replication in patients who received nucleoside analogues and may allow patients to preserve future treatment options.
Nausea, malaise and fatigue, headache, vomiting and diarrhea are the most commonly reported side effects associated with Ziagen.
In a separate release Monday, Glaxo Wellcome and Vertex Pharmaceuticals Inc. (VRTX) also reported a triple therapy of Agenerase, Epivir and Retrovir appeared effective in reducing viral load level below the limit of detection of standard assays, of 400 copies/ml.
Glaxo Wellcome develops and markets pharmaceuticals.
