Abstract: APOBEC3G/F-associated E138K, M184I and M230I appeared within clonal sequences containing in-frame STOP codons in 2/3 (66%), 5/5 (100%) and 4/4 (100%) of the samples.
Abstract: In a large pan-European case-control study investigating the clinical relevance of pre-existing DRMVs using 454 pyrosequencing, the six most prevalent plasma DRMVs detected corresponded to G-to-A nucleotide mutations (V90I, V106I, V108I, E138K, M184I and M230I).
Abstract: Mutations E138K, M184I and M230I co-occurred in the same sequence as APOBEC3G/F signatures in 3/9 (33%), 5/11 (

Method: Major RPV resistance-associated mutations (RPV-RAMs) were defined based on data from the clinical trials, phenotypic RPV resistance analyses, and package inserts: K101E/P, E138A/G/K/Q/R, V179L, Y181C/I/V, Y188L, H221Y, F227C, M230I/L, and the mutational combination of L100I+K103N.
Systematic review to determine the prevalence of transmitted drug resistance mutations to rilpivirine in HIV-infected treatment-naive persons.
Abstract: Pooled results from the Stanford database (n=52,680) correlated with these findings indicating a low prevalence of 8/9 rilpivirine mutations (<0.1%), except for E138A/G/K/Q/R (2.9%, 95% CI 1.8, 4.4).
Abstract: The prevalence of E138A/G/K/Q/R mutations is higher (0.7%) and varies according to geographical region and HIV subtype.
Abstract: Two mutations were mo
Clinical Outcomes of Virologically-Suppressed Patients with Pre-existing HIV-1 Drug Resistance Mutations Switching to Rilpivirine/Emtricitabine/Tenofovir Disoproxil Fumarate in the SPIRIT Study.
Abstract: Mutations potentially affecting RPV activity, including E138A/G/K/Q, Y181C, and H221Y, were detected in isolates from 11 patients by one or both assays.

Abstract: Compounds 6a, 14c, and 14d showed high potency against the 1b-resistant E138K mutated viral strain as well as good balance between anti-HIV-1 activity and desirable druglike properties.
Abstract: From the perspective of optimizing future NNRTI compounds as clinical trial candidates, computational modeling results provided valuable information about how the R(1) group might provide greater efficacy against the E138K mutant.
Abstract: Three series (6, 13, and 14) of new diarylaniline (DAAN) analogues were designed, synthesized, and evaluated for anti-HIV potency, especially against the E138K viral strain with a major mutation conferring resistance to the new-generation non-nucleoside reverse transcriptase inhibitor drug rilpivirine (1b).
Introduction: Guided by the prior SAR results, we
Role of Rilpivirine and Etravirine in Efavirenz and Nevirapine-Based Regimens Failure in a Resource-Limited Country: A Cross- Sectional Study.
Introduction: According to the ECHO and THRIVE studies, E138K was the most frequently selected mutation (45%) detected in ARVnaive patients who
Result: Interestingly, the most prevalent NNRTI-RAM E138K reported in the ECHO and THRIVE studies were rarely detected in this study.
Result: The authors observed only 2 patients (0.4%) that failed EFV-based regimen had the E138K mutation and none from the failed NVP-based regimen (p = 0.03).
Discussion: Another mutation that was investigated was the E138K because it was reported to be 77% prevalent in RPV-failed patients from the ECHO and THRIVE studies.
Discussion: Likewise, our study detected only 0.4% of patients that have failed the first-line NNRTI regimen with E138K.

Introduction: A partial list of NNRTI resistance mutations include: L100I, K103N, V106A, E138K, Y181C, Y188L, and H221Y; these mutations can occur singly, or in combinations.
Introduction: DOR loses potency against a number of NNRTI-resistant mutants; however, DOR is generally effective against mutants that reduce the potency of RPV, although DOR did lose some potency against E138K.
Introduction: In addition, viruses that grew out in an in vitro selection with RPV or a compound closely related to RPV had the RT mutations K101E or
Effect on HIV-1 viral replication capacity of DTG-resistance mutations in NRTI/NNRTI resistant viruses.

Figure: d E138K series including NL4.3E138K, NL4.3R263K-E138K, and NL4.3H51Y/R263K-E138K.
Discussion: Given that the R263K substitution has been reported in some INSTI-naive patients in the SAILING study and in tissue culture selections, we aimed to investigate the effects of R263K and its secondary mutation H51Y toge
