BACKGROUND: Doravirine (DOR) is a non-nucleoside reverse transcriptase inhibitor (NNRTI) approved for HIV-1 infection treatment. Because of its genetic barrier, DOR appears to be a good alternative in switch strategies compared to other NNRTI. Our aim was to evaluate the percentage of people living with HIV (PLWHIV) followed in our center who could be eligible to a DOR-based regimen. METHODS: We collected data from all treatment-experienced PLWHIV, never exposed to DOR and with a demonstrated virological suppression. We analyzed previous genotypic analyses, clinical history, and previous exposure to NNRTIs. RESULTS: We analyzed data from 653 patients, whose characteristics are shown in Table 1. 59% of them presented no resistance mutation (RAM) at genotypic analysis. The most common DOR-related RAM were V106A, Y181V, and Y188L. We also analyzed RAM that can possibly interfere with combination therapy (mostly K65R and M184V). In the end, 81.8% of our patients results to be eligible for a DOR-based therapy regimen. CONCLUSIONS: DOR represents a good option for switch strategies in virological suppressed PLWHIV. It seems to have a higher genetic barrier and a lower risk for resistance mutation development compared to other NNRTI. In our cohort, we found 81.8% of patients who could be eligible for a regimen containing DOR and almost 2/3 of patients who can be treated with the fixed-dose combination DOR/3TC/TDF.

Abstract

BACKGROUND: Doravirine (DOR) is a non-nucleoside reverse transcriptase inhibitor (NNRTI) approved for HIV-1 infection treatment. Because of its genetic barrier, DOR appears to be a good alternative in switch strategies compared to other NNRTI. Our aim was to evaluate the percentage of people living with HIV (PLWHIV) followed in our center who could be eligible to a DOR-based regimen. METHODS: We collected data from all treatment-experienced PLWHIV, never exposed to DOR and with a demonstrated virological suppression. We analyzed previous genotypic analyses, clinical history, and previous exposure to NNRTIs. RESULTS: We analyzed data from 653 patients, whose characteristics are shown in Table 1. 59% of them presented no resistance mutation (RAM) at genotypic analysis. The most common DOR-related RAM were V106A, Y181V, and Y188L. We also analyzed RAM that can possibly interfere with combination therapy (mostly K65R and M184V). In the end, 81.8% of our patients results to be eligible for a DOR-based therapy regimen. CONCLUSIONS: DOR represents a good option for switch strategies in virological suppressed PLWHIV. It seems to have a higher genetic barrier and a lower risk for resistance mutation development compared to other NNRTI. In our cohort, we found 81.8% of patients who could be eligible for a regimen containing DOR and almost 2/3 of patients who can be treated with the fixed-dose combination DOR/3TC/TDF.
