Mexico City (ots/PRNewswire) - - HIV-Infected Women and Non-Whites New to Antiretroviral Therapy Respond Similarly to Men and Whites
Initial treatment regimens containing once-daily or twice-daily dosing of Abbott's (NYSE: ABT) protease inhibitor Kaletra(R) (lopinavir/ritonavir) tablet provided similar results for controlling the virus (reducing the amount of HIV-1) and improving the immune system (increasing CD4 cells) in women compared to men and in non-whites compared to whites, according to 48-week data presented by Abbott today at the XVII International AIDS Conference (AIDS 2008).
A retrospective sub-analysis of study M05-730 at week 48 of 96 weeks offered data on the impact of gender and race on a Kaletra-based regimen. Women and non-whites have traditionally been underrepresented in HIV studies, although these patient groups increasingly account for the vast majority of HIV infections. According to the World Health Organization, by the end of 2007, 22.5 million of the total 33.2 million people infected with HIV lived in sub-Saharan Africa. Additionally, 15.4 million of the total number of HIV-infected patients worldwide are women.
"The results showed that regardless of gender or race, Kaletra dosed once-daily or twice-daily as part of a treatment regimen achieved consistent virologic suppression in patients new to antiretroviral therapy," said Scott Brun, M.D., divisional vice president, Infectious Diseases and Immunology Development, Global Pharmaceutical Research and Development, Abbott. "Additionally, the Kaletra tablet formulation is a convenient HIV treatment option that can be taken with or without food and does not require refrigeration, which is particularly important to patients in the developing world who are disproportionately affected by HIV."
M05-730 Analysis Results
Through 48 weeks, the proportions of males and females who achieved an undetectable HIV viral load were similar. In addition, the proportions of whites and non-whites who achieved an undetectable HIV viral load were similar. Specifically, 72 percent of women and 78 percent of men, and 75 percent of non-whites and 77 percent of whites had undetectable HIV viral loads (less than 50 copies/mL) at 48 weeks.
CD4+ cell count mean increases over 48 weeks were similar for females and males, independent of baseline CD4+ cell count, except among women with baseline CD4+ cell counts of fewer than 50 cells/mm3, who experienced statistically significant greater mean increases in CD4+ cell counts than males. In addition, CD4+ cell count mean increases over 48 weeks were similar for whites and non-whites. At 48 weeks, the overall rate of moderate to severe and related adverse events of diarrhea was 15.8 percent. A similar rate of diarrhea was observed in whites (17.8 percent), while non-whites experienced a rate of 9.7 percent.
"This sub-analysis of M05-730 provides additional clinical information on race and gender response with Kaletra," said Joseph Gathe, Jr., M.D., clinical instructor, Department of Internal Medicine, Baylor College of Medicine. "The information can help physicians in making treatment decisions for the patient populations most affected by HIV."
About the M05-730 Study -- 48-week Data
Design and Primary Endpoints:
-- M05-730 study is a 96-week Phase III open-label, randomized, multi-center, multi-country study that enrolled 664 ARV-naive patients with HIV-1 RNA >1000 copies/mL and any CD4+ T-cell count. Patients were randomized equally to lopinavir/ritonavir 800/200 mg once-daily soft gel capsule (SGC), 400/100 mg twice-daily (BID) SGC, 800 mg/200 mg once-daily tablet or 400/100 mg twice-daily tablet for eight weeks. All patients also received emtricitabine (FTC) 200 mg once-daily and tenofovir disoproxil fumarate 300 mg once-daily. At week eight, all patients receiving SGC were switched to the tablet formulation of Kaletra, matching their previous dosing schedule of once- or twice-daily.
-- The primary efficacy endpoint was the proportion of patients with HIV-1 RNA <50 copies/mL at week 48, using an intent to treat noncompleter equals failure approach comparing once-daily and twice-daily groups. A secondary efficacy endpoint was mean change from baseline in CD4+ T-cell count.
-- The primary safety endpoint was the proportion of patients reporting a treatment-emergent adverse event of diarrhea during the first eight weeks of dosing. Additional safety analyses included the proportion of subjects reporting treatment-emergent adverse events, grade 3+ lab abnormalities, and mean changes from baseline for lab determinations through 48 weeks.
Primary Efficacy Results:
-- At week 48, the primary efficacy analysis showed that 77 percent of the once-daily-treated patients and 76 percent of the twice-daily treated patients achieved a viral load <50 copies/mL. The once-daily regimen was determined to be non-inferior to the twice-daily regimen.
-- Through week 48, 14.7 percent and 16.6 percent of the patients discontinued treatment on the once-daily and twice-daily regimens, respectively. A similar percentage of patients on the once-daily regimen discontinued due to adverse events, as on the twice-daily regimen (4.8 percent and 3 percent, respectively).
-- With respect to the comparison of the SGC to the tablet formulation through week eight, there were no statistically significant differences in the following areas: the number of patients discontinuing due to gastrointestinal adverse events or other adverse events; the incidence of treatment-emergent adverse events of diarrhea of any severity and of moderate or greater severity and related to the study drug; the proportion of patients with Grade 3+ lab abnormalities; or the mean change from baseline for total cholesterol or triglycerides at any time point during the first eight weeks of treatment.
-- The most common moderate/severe related adverse events in the once-daily and twice-daily groups respectively were: diarrhea (17 percent versus 15 percent), nausea (seven percent versus five percent), vomiting (three percent versus four percent), and increased triglycerides (two percent in both groups). There was no statistical difference between the groups.
-- At week 48, the overall impact of Kaletra, dosed once-daily or twice-daily, on grade 3-4 lab abnormalities, including cholesterol and triglycerides, the liver enzymes, SGOT/AST, and creatinine clearance was similar.
-- At week 48, there was a statistically significant difference in the increase of total cholesterol between the once-daily and twice-daily group.
