As a consequence, it was proposed that treatment and follow-up in the monotherapy arm should be continued, for those patients with a completely satisfactory virological response (<50 copies/mL). This amendment was approved by the Ethics Committees, and all patients on LPV/r

monotherapy who remained on follow-up in the study signed an additional informed consent stating that they were informed of the cessation of the follow-up of the Rucaparib order triple-drug arm. The results presented herein focus on a noncomparative outcome description of patients initially randomized to receive LPV/r monotherapy, and who continued with LPV/r post week 48. A total of 83 subjects were initially randomized to the monotherapy arm of the study. Overall, 48 of the 83 patients initially randomized to LPV/r monotherapy were still

on LPV/r monotherapy at week 96 (Fig. 1). At week 96, by intent-to-treat (ITT) analysis, 39 of 83 patients (47%) had a plasma HIV RNA <50 copies/mL. Considering the 56 patients on LPV/r monotherapy with buy Forskolin HIV RNA <50 copies/mL at week 48, 46 of these patients remained on LPV/r monotherapy at week 96 and 10 patients discontinued before week 96. Among these 56 patients, virological response was sustained for 38 patients (68%), five (9%) had HIV RNA between 50 and 400 copies/mL, and three (5%) had HIV RNA >400 copies/mL (Table 1). Considering the 11 patients on LPV monotherapy with HIV RNA >50 copies/mL at week 48, one patient had a sustained virological response on LPV monotherapy, five patients discontinued the treatment, four patients had treatment alterations and one patient had a missing HIV RNA value at week 96 (Table 1 and Fig. 1). The median increase (interquartile range) in CD4 cell count from baseline was 165 (100–248) cells/μL (n=47 patients). In addition, the allocated treatment was changed 4-Aminobutyrate aminotransferase for seven patients (8%): six patients underwent treatment intensification with zidovudine/lamivudine (ZDV/3TC) (3 before

week 48, and 3 after week 48) and the remaining patient discontinued treatment after week 48 (Fig. 1). During the entire 96-week treatment period, PI-associated major resistance mutations were evident in five of 83 patients (6%): mutations M46I and L63P in one patient at week 40 (concomitant HIV RNA 2.9 log10 copies/mL), L76V in one patient at week 44 (concomitant HIV RNA 2.8 log10 copies/mL), I13V, M46I and L76V in one patient at week 62 (concomitant HIV RNA 2.6 log10 copies/mL), L10F and V82A in one patient at week 76 (concomitant HIV RNA 3.1 log10 copies/mL), and L76V in one patient at week 90 (concomitant HIV RNA 2.5 log10 copies/mL). These mutations did not result in any significant phenotypic or genotypic resistance to LPV/r [15].
