Abstract:Background: To investigate the impact of switching from stable Combined Antiretroviral
Therapy (cART) to single-tablet regimen (RPV/FTC/TDF=EVIPLERA®
/COMPLERA®) on patient-
reported outcomes in HIV-infected adults who cannot tolerate previous cART, in a real-world
setting.
Methods: PRO-STR is a 48-week observational, prospective, multicenter study. Presence and magnitude
of symptoms (main endpoint), health-related quality-of-life (HRQoL), adherence, satisfaction
with treatment and patient preferences were assessed.
Results: Three hundred patients with 48-week follow-up, who switched to EVIPLERA® (mean age:
46.6 years; male: 74.0%; 74.7% switched from a non-nucleoside reverse-transcriptase-inhibitor,
25.3% from a protease inhibitor + ritonavir) were included. There was no statistical difference in
median CD4+ cell count (baseline: 678.5 cells/mm3; 48-week: 683.0 cells/mm3) neither in virological
suppression (≤50 copies/mL) (baseline: 98.3%; 48-week: 95.3%). The most frequent reasons for
switching were neuropsychiatric (62.3%), gastrointestinal (19.3%) and biochemical/metabolic
(19.3%) events. Only 7.7% of patients permanently discontinued therapy. At 48-week, all outcomes
showed an improvement compared to baseline. Overall, there was a significant decrease (pvalue≤
0.05) in number and magnitude of symptoms, while HRQoL, satisfaction and adherence
improved significantly. Most patients prefered EVIPLERA® than previous cART. According to the
type of intolerance, HRQoL was improved, but only significantly in patients with neuropsychiatric
and gastrointestinal symptoms. Adherence improved significantly in patients with metabolic
disturbances and satisfaction with EVIPLERA® was higher in the three groups.
Conclusion: Switching to EVIPLERA® from non-nucleoside reverse-transcriptase-inhibitor or protease
inhibitor-based regimens due to toxicity, improved the presence/magnitude of symptoms,
HRQoL, and preference with treatment. EVIPLERA® maintained a virological response, CD4+ cell
count and maintained or improved adherence.
