    (Springer Nature, 2022) Quintanilha, Julia C.F.; Wang, Jin; Sibley, Alexander B.; Jiang, Chen; Etheridge, Amy S.; Shen, Fei; Jiang, Guanglong; Mulkey, Flora; Patel, Jai N.; Hertz, Daniel L.; Dees, Elizabeth Claire; McLeod, Howard L.; Bertagnolli, Monica; Rugo, Hope; Kindler, Hedy L.; Kelly, William Kevin; Ratain, Mark J.; Kroetz, Deanna L.; Owzar, Kouros; Schneider, Bryan P.; Lin, Danyu; Innocenti, Federico; Medicine, School of Medicine
    Background: Hypertension and proteinuria are common bevacizumab-induced toxicities. No validated biomarkers are available for identifying patients at risk of these toxicities. Methods: A genome-wide association study (GWAS) meta-analysis was performed in 1039 bevacizumab-treated patients of European ancestry in four clinical trials (CALGB 40502, 40503, 80303, 90401). Grade ≥2 hypertension and proteinuria were recorded (CTCAE v.3.0). Single-nucleotide polymorphism (SNP)-toxicity associations were determined using a cause-specific Cox model adjusting for age and sex. Results: The most significant SNP associated with hypertension with concordant effect in three out of the four studies (p-value <0.05 for each study) was rs6770663 (A > G) in KCNAB1, with the G allele increasing the risk of hypertension (p-value = 4.16 × 10-6). The effect of the G allele was replicated in ECOG-ACRIN E5103 in 582 patients (p-value = 0.005). The meta-analysis of all five studies for rs6770663 led to p-value = 7.73 × 10-8, close to genome-wide significance. The most significant SNP associated with proteinuria was rs339947 (C > A, between DNAH5 and TRIO), with the A allele increasing the risk of proteinuria (p-value = 1.58 × 10-7). Conclusions: The results from the largest study of bevacizumab toxicity provide new markers of drug safety for further evaluations. SNP in KCNAB1 validated in an independent dataset provides evidence toward its clinical applicability to predict bevacizumab-induced hypertension.

    Identification of Reduced ERAP2 Expression and a Novel HLA Allele as Components of a Risk Score for Susceptibility to Liver Injury Due to Amoxicillin-Clavulanate
    (Elsevier, 2023) Nicoletti, Paola; Dellinger, Andrew; Li, Yi Ju; Barnhart, Huiman X.; Chalasani, Naga; Fontana, Robert J.; Odin, Joseph A.; Serrano, Jose; Stolz, Andrew; Etheridge, Amy S.; Innocenti, Federico; Govaere, Olivier; Grove, Jane I.; Stephens, Camilla; Aithal, Guruprasad P.; Andrade, Raul J.; Bjornsson, Einar S.; Daly, Ann K.; Lucena, M. Isabel; Watkins, Paul B.; Drug-Induced Liver Injury Network (DILIN); International Drug-Induced Liver Injury Consortium (iDILIC); Prospective European Drug-Induced Liver Injury (Pro-Euro DILI) Investigators; Medicine, School of Medicine
    Background & aims: Drug-induced liver injury (DILI) due to amoxicillin-clavulanate (AC) has been associated with HLA-A∗02:01, HLA-DRB1∗15:01, and rs2476601, a missense variant in PTPN22. The aim of this study was to identify novel risk factors for AC-DILI and to construct a genetic risk score (GRS). Methods: Transcriptome-wide association study and genome-wide association study analyses were performed on 444 AC-DILI cases and 10,397 population-based controls of European descent. Associations were confirmed in a validation cohort (n = 133 cases and 17,836 population-based controls). Discovery and validation AC-DILI cases were also compared with 1358 and 403 non-AC-DILI cases. Results: Transcriptome-wide association study revealed a significant association of AC-DILI risk with reduced liver expression of ERAP2 (P = 3.7 × 10-7), coding for an aminopeptidase involved in antigen presentation. The lead eQTL single nucleotide polymorphism, rs1363907 (G), was associated with AC-DILI risk in the discovery (odds ratio [OR], 1.68; 95% CI, 1.23-1.66; P = 1.7 × 10-7) and validation cohorts (OR, 1.2; 95% CI, 1.04-2.05; P = .03), following a recessive model. We also identified HLA-B∗15:18 as a novel AC-DILI risk factor in both discovery (OR, 4.19; 95% CI, 2.09-8.36; P = 4.9 × 10-5) and validation (OR, 7.78; 95% CI, 2.75-21.99; P = .0001) cohorts. GRS, incorporating rs1363907, rs2476601, HLA-B∗15:18, HLA-A∗02:01, and HLA-DRB1∗15:01, was highly predictive of AC-DILI risk when cases were analyzed against both general population and non-AC-DILI control cohorts. GRS was the most significant predictor in a regression model containing known AC-DILI clinical risk characteristics and significantly improved the predictive model. Conclusions: We identified novel associations of AC-DILI risk with ERAP2 low expression and with HLA-B∗15:18. GRS based on the 5 risk variants may assist AC-DILI causality assessment and risk management.
