6% (n = 8) vs. 11.8% (n = 63), respectively]. However, the severity of rash was similar between genders, with low proportions of male and female patients in the etravirine group reporting grade 3 rash (1.1% vs. 3.3%, respectively), and no patients reporting grade 4 rash. In total, 7.7% and 13.6% of etravirine and placebo patients had a previous history of NNRTI-related rash; prior history of NNRTI-related rash had no effect on the frequency of rash in either treatment group. Thus, in the etravirine group, the occurrence of rash in patients with an NNRTI-related rash history was

21.7% (n = 10) vs. 20.4% (n = 113) for those without a prior history, and in the placebo group the frequencies were AZD2281 datasheet 14.6% (n = 12) vs. 11.3% (n = 59), respectively. Regardless of severity or causality,

the frequency of hepatic AEs (from all system order classes combined) was low and similar between the treatment groups (8.7% vs. 7.1% in the etravirine and placebo groups, respectively; difference = 1.6%: 95% CI −1.5 to 4.6; P = 0.3370, Fisher’s exact test). Etoposide purchase The frequency of grade 3 or 4 hepatic AEs (all system order classes combined) was similar between the treatment groups; 4.2% (n = 21) and 3.0% (n = 18) in the etravirine and placebo groups, respectively. Permanent discontinuation because of hepatic AEs was infrequent in both arms (1.3% for etravirine and 0.7% for placebo). acetylcholine The most commonly reported hepatic AEs occurred in the system order class ‘investigations’

and were related to increases in liver enzymes (4.8% vs. 4.3% in the etravirine and placebo groups, respectively; P = 0.6808) and there were three cases of hepatitis reported (one in the etravirine group and two in the placebo group). Grade 3 or 4 ALT and AST increases were low in each treatment group; 4.4% vs. 2.3% (P = 0.0540) and 3.9% vs. 2.5% (P = 0.1899) in the etravirine and placebo groups, respectively. No increase over time was observed in ALT or AST levels (Fig. 2). Grade 3 or 4 increases from baseline in fasted lipid-related laboratory abnormalities [triglycerides, total cholesterol, LDL-cholesterol and high-density lipoprotein (HDL)-cholesterol] generally occurred at a similar frequency in the etravirine and placebo groups; however, a tendency for a higher frequency of grade 3 or 4 elevated triglycerides and total cholesterol with etravirine vs. placebo was observed (triglycerides: 11.3% vs. 7.0%, P = 0.0117; total cholesterol: 9.2% vs. 6.0%, P = 0.0379; LDL-cholesterol: 9.4% vs. 8.1%, P = 0.4704). Changes from baseline over time in mean lipid levels were comparable between treatment groups (Fig. 3). Small increases compared with baseline were observed for total cholesterol (0.5 mmol/L for both groups), HDL-cholesterol (0.1 mmol/L for both groups) and LDL-cholesterol (0.5 mmol/L for both groups) (Fig. 3).
