Brief summary
Following the initiation of Doravirine (DOR) regimen among people living with HIV (PLWH), the study will aim to assess effectiveness, discontinuation, and resistance over the 12-month period. Retrospective data from 500 patients is planned to be collected from 6 - 10 European sites. Cohort 1 : 400 patients, 100 treatment naïve and 300 virally suppressed patients switching from a 1st or second line treatment, Cohort 2: 50 patients with NNRTI mutations (other than DOR), Cohort 3: 50 patients with NNRTI mutations (including DOR). The study will be conducted through collaboration with the NEAT ID Network, a well-established network of clinical sites across Europe.

Eligibility
Inclusion criteria
* are HIV positive male or female * are aged ≥18 years * were prescribed and received at least one dose of DOR (without initial dose adjustment). * have started/been switched to DOR for at least 12 months at time of data collection * had a resistance genotype available before starting DOR Cohort 1 Specific Inclusion Criteria * had no evidence of DOR-associated resistance mutation * were on DOR containing ART regimen that also contained 2 fully active nucleos(t)ides and patient had no documented NRTI resistance mutations to the two NRTIs in the combination. * Patients who, at the time of initiation, were: 1. Category 1: HIV treatment naïve OR 2. Category 2: Virologically suppressed (HIV-1 RNA \<50 copies/mL) for at least 6 months with no evidence of prior virological failure with agents of the NNRTI class Patients in category 1 and 2 above who have NNRTI mutations that do not impact on DOR (K103N, Y181C, and G190A) using the Stanford algorithm (https://hivdb.stanford.edu/hivdb/by-mutations) can be included in this study. Cohort 2 Specific Inclusion Criteria * must have evidence of NNRTI associated resistance mutations (other than DOR) according to Stanford algorithm * their DOR-containing ART will contain 2 NRTIs but will not include an INSTI and/or a bPI. * had no documented resistance to the other drugs in the combination. * Patients who, at the time of initiation, were: 1. Category 1: HIV treatment naïve OR 2. Category 2: Virologically suppressed (HIV-1 RNA \<50 copies/mL) for at least 6 months Cohort 3 Specific Inclusion Criteria * ART naïve or virologically suppressed (HIV-1 RNA \<50 copies/mL) for at least 6 months at the time of DOR initiation
Exclusion criteria
* Patients with no documented resistance testing. * Patients with no genotype available at DOR initiation * Patients enrolled in DOR trials Cohort 1 specific
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Proportion virologically suppressed patients at week 48 who have remained on DOR. | Week 48 after DOR initiation | Proportion of patients, virologically suppressed/undetectable (\<50 copies/mL) at week 48 who have remained on DOR. |
| Proportion of patients with virologic failure (Cohort 1 - treatment naive) | on or after week 48 after DOR initiation | i. Two consecutive HIV RNA VL levels ≥50 copies/mL after reaching at HIV RNA \< 50 copies/mL or ii. One HIV RNA VL level ≥50 copies/mL and DOR regimen is discontinued immediately or at next hospital visit, after reaching HIV RNA \< 50 copies/mL |
| Proportion of patients with virologic failure (Cohort 2 - treatment suppressed) | up to 12 months after initiation of DOR | i. Two consecutive HIV RNA VL levels ≥50 copies/mL after reaching at HIV RNA \< 50 copies/mL or ii. One HIV RNA VL level ≥50 copies/mL and DOR regimen is discontinued immediately or at next hospital visit, after reaching HIV RNA \< 50 copies/mL |
| Proportion of patients switched for reasons other than virological failure. | up to 12 months after initiation of DOR | Proportion of patients switched at any time point for reasons other than virological failure. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of patients with confirmed virologic failure, commonly used to make treatment related clinical decisions (Cohort 1 - treatment naive) | on or after week 48 after DOR initiation | i. Two consecutive HIV RNA VL levels ≥200 copies/mL after reaching HIV RNA \< 200 copies/mL or ii. One HIV RNA VL level ≥200 copies/mL and DOR regimen is discontinued immediately or at next hospital visit, after reaching HIV RNA \< 200 copies/mL. |
| Estimated proportion of patients with low level viremia | up to 12 months after initiation of DOR | Estimated proportion of patients with low level viremia (≥50-\<200 copies/mL) |
| HIV resistance subtypes for patients with virologic failure | during the 12-month data collection period. | HIV resistance mutations subtypes for all DOR treated patients with virologic failure |
