Abstract:
STAR/STELLA is a prospective[TS1] cohort of HIV patients initiated on LPV/r‐based ART in routine clinical practice. Here, virologic/immunologic outcomes and safety data of LPV/r‐based first‐line ART over a period of 144 weeks are presented. Methods Analysis included ART‐naïve patients who started on LPV/r before July 2011 (i.e. patients with ≥144 weeks since ART initiation). Safety evaluation included adverse events (AEs), discontinuations (disc.) due to AEs, and symptoms assessed with the self‐report ACTG Symptom Distress Module (ASDM; high score=high distress). Results 1409 patients were included (84% men; 76% on TDF+FTC), with a large proportion in advanced stages of HIV disease at ART initiation: 48% had a CD4 count 〈 200/µL, 55% had HIV RNA levels 〉 100,000 c/mL. 53% of patients (n=746) remained on LPV/r for at least 144 weeks. Time on drug was longer for patients initiated before 2008 than in subsequent years (HRadj, 1.2; 95% CI, 1.0–1.4; p=0.04; hazard ratio adjusted for CD4 〈 200/µL and HIV RNA 〉 100,000 c/mL). Main reasons for d/c were: AEs (19.3%), patient wish (9.2%), virologic/immunologic failure (4.1%), and noncompliance (2.8%); 1.6% of patients died. By week 144, 33% of patients had 〉 750 CD4/µL (Kaplan–Meier estimate): time to CD4 count 〉 750 c/ µL, stratified by BL CD4 count, is shown in Figure 1 . ITT snapshot analysis of HIV RNA 〈 50 c/mL at week 144 showed 51% responders (failure=d/c due to virologic/immunologic failure, AEs, noncompliance, death). In patients on LPV/r for 144 weeks, median CD4 change was +314/µL (IQR, 205–440/µL), 87% had HIV RNA levels 〈 50 c/mL. In patients who discontinued therapy prior to week 144, 56% had an HIV RNA level 〈 50 c/mL. In 51% of patients, ≥1 AE was reported (most commonly diarrhoea, 35%); 11% of patients had ≥1 AE of grade 3 or 4 (diarrhoea, 4.5%). In patients who remained on LPV/r based ART through 144 weeks, median ASDM score decreased significantly from 9 at BL (IQR, 3–21) to 2.5 at Week 144 (IQR, 0–8.5, p 〈 0.001). Conclusion In the STAR/STELLA observational cohort, LPV/r‐based ART demonstrated good virologic outcomes and immune recovery in ART‐naïve patients over 144 weeks, with significant improvements in symptom distress. Over three years, 〈 5% of patients discontinued LPV/r due to virologic/immunologic failure, and 19% of patients discontinued for tolerability reasons.
