Abstract
BACKGROUND
Doravirine is a non-nucleoside reverse transcriptase inhibitor with demonstrated efficacy as a third agent in treatment-naive and treatment-experienced people living with HIV (PLWH) in registration studies. However, limited real-world data are available.
METHODS
By searching electronic health care records, PLWH using doravirine-based regimens were selected with at least 1 year of follow-up after their first prescription. All stable PLWH who were switched to a doravirine-based regimen were included in the analysis. The primary outcome was the durability of a doravirine-based regimen 1 year after prescription. Reasons for stopping were also collected. Secondary outcomes for PLWH continuing a doravirine-based regimen after 1 year were routine laboratory assessment, body mass index, and differences in medication costs compared with their previous cART.
RESULTS
A total of 687 patients (92% men) were included from September 2019 to August 2022: 97.7% switched to doravirine/tenofovir/lamivudine (DOR/TDF/3TC). After 1 year, 94/687 (13.6%) PLWH stopped this therapy. The main reason for discontinuation was patient-reported adverse events in 70/687 (10.2%). Medical reasons for discontinuation included increased alanine tranaminase levels in 6/687 (0.9%), decreased estimated glomerular filtration rate in 3/687 (0.4%), and precautions after diagnosis of osteoporosis in 2/687 (0.3%) patients. Virologic failure occurred in 4/687 cases (0.6%), and 1 case demonstrated resistance mutations. The secondary outcomes demonstrated a statistically significant increase in alanine tranaminase levels and decrease in LDL-c levels. The switch to a doravirine-based regimen in the Netherlands reduced medication costs by 27%.
CONCLUSIONS
This study demonstrated that switching to a doravirine-based regimen, mostly DOR/TDF/3TC, was highly effective and generally well tolerated, with substantial cost savings.
